2026 Federal Income Tax Brackets
The United States utilizes a progressive tax system. You only pay your highest marginal tax rate on the portion of your income that falls strictly within that specific structural bracket.
Single Filers
| Tax Rate | Taxable Income Bracket (2026) |
| 10% | $0 to $12,400 |
| 12% | $12,401 to $50,400 |
| 22% | $50,401 to $105,700 |
| 24% | $105,701 to $201,775 |
| 32% | $201,776 to $256,225 |
| 35% | $256,226 to $640,600 |
| 37% | $640,601 or more |
Married Filing Jointly
| Tax Rate | Taxable Income Bracket (2026) |
| 10% | $0 to $24,800 |
| 12% | $24,801 to $100,800 |
| 22% | $100,801 to $211,400 |
| 24% | $211,401 to $403,550 |
| 32% | $403,551 to $512,450 |
| 35% | $512,451 to $768,700 |
| 37% | $768,701 or more |
Head of Household
| Tax Rate | Taxable Income Bracket (2026) |
| 10% | $0 to $17,700 |
| 12% | $17,701 to $67,450 |
| 22% | $67,451 to $105,700 |
| 24% | $105,701 to $201,775 |
| 32% | $201,776 to $256,200 |
| 35% | $256,201 to $640,600 |
| 37% | $640,601 or more |
Marginal vs. Effective Note: If you are single with $80,000 in taxable income, you are in the 22% marginal bracket. However, your effective tax rate is only 15.39% because your income is taxed progressively across the 10%, 12%, and 22% tiers sequentially.
How Your Gross Pay Becomes Net Pay
Your paycheck starts with gross pay and ends with net pay. Gross pay is your total earnings before taxes and deductions. Net pay is the final amount you actually receive after federal tax, state tax, FICA taxes, retirement contributions, health insurance, and other deductions are subtracted.
For salaried employees, gross pay is usually calculated by dividing annual salary by the number of pay periods in the year. For hourly employees, gross pay is usually calculated by multiplying hourly rate by hours worked, including overtime when applicable.
Gross Pay vs Net Pay
| Paycheck Term | Meaning | Example |
|---|---|---|
| Gross Pay | Total earnings before taxes and deductions | Salary, hourly wages, overtime, bonuses, or commissions |
| Taxable Pay | Income left after eligible pre-tax deductions are removed | Gross pay minus traditional 401(k), HSA, FSA, or qualifying health premiums |
| Net Pay | Final take-home pay after taxes and deductions | The amount deposited into your bank account |
What Usually Comes Out of Gross Pay?
Common paycheck deductions may include:
- Federal income tax
- State income tax
- Social Security tax
- Medicare tax
- Traditional 401(k), HSA, or FSA contributions
- Health, dental, or vision insurance premiums
- Roth retirement contributions or other post-tax deductions
Social Security and Medicare are part of FICA taxes. These payroll taxes are calculated separately from federal income tax and are explained in detail below.
Simple Paycheck Formula
Gross Pay − Pre-Tax Deductions − Taxes − Post-Tax Deductions = Net Pay
This is the basic formula behind most paycheck calculations. Your final take-home pay may change based on your filing status, Form W-4 settings, pay frequency, state, local taxes, benefits, and retirement contributions.
Pre-Tax, Post-Tax and Common Paycheck Deductions
Understanding paycheck deductions is important because your gross pay is not the same as your take-home pay. Before your salary reaches your bank account, your employer may withhold federal income tax, state income tax, Social Security, Medicare, retirement contributions, health insurance premiums, and other benefit deductions.
Some deductions reduce your taxable income before taxes are calculated. Others are taken out after taxes have already been applied. Knowing the difference between pre-tax deductions, post-tax deductions, and mandatory payroll taxes can help you better estimate your net paycheck.
What Are Pre-Tax Deductions?
Pre-tax deductions are taken out of your gross pay before certain taxes are calculated. This can lower your taxable income and may reduce your federal and state income tax withholding.
Common pre-tax deductions include:
Traditional 401(k) / 403(b) retirement contributions
Health insurance premiums under a qualifying Section 125 plan
HSA (Health Savings Account) contributions
FSA (Flexible Spending Account) contributions
Dental and vision insurance premiums
Example: If you earn $65,000 per year and contribute $5,000 to a traditional 401(k), your federal taxable income may be reduced to $60,000 before the standard deduction and tax brackets are applied. This lowers your current federal income tax withholding.
Note on Tax Behavior: Not every pre-tax deduction affects every tax the same way. Traditional 401(k) contributions reduce federal income tax, but they do not reduce Social Security or Medicare wages. Qualifying Section 125 health insurance premiums are highly tax-efficient because they reduce federal income tax, state income tax, Social Security, and Medicare wage bases.
What Are Post-Tax Deductions?
Post-tax deductions are taken out after federal, state, Social Security, and Medicare taxes have already been calculated. These deductions do not reduce your current taxable income, but they provide future benefits or fulfill legal mandates.
Common post-tax deductions include:
Roth 401(k) / Roth 403(b) contributions
Roth IRA payroll deductions (if offered by employer)
Union dues
Charitable payroll contributions
Wage garnishments / Court-ordered payments
Example: A Roth 401(k) does not reduce your taxable income today. You pay taxes on that money now, but your qualified withdrawals during retirement grow and come out completely tax-free.
Common Paycheck Deductions and How They Affect Net Pay
| Deduction | Pre-Tax or Post-Tax? | How It Affects Your Paycheck (2026 Rules) |
|---|---|---|
| Federal Income Tax | Tax Withholding | Based on taxable income, filing status, W-4 settings, pay frequency, and federal tax brackets. |
| State Income Tax | Tax Withholding | Varies by state. 9 states have no state income tax, while others use flat or progressive tax rates. |
| Social Security Tax | Payroll Tax | Employee rate is a flat 6.2% calculated on gross wages up to the 2026 annual wage base cap of $184,500. |
| Medicare Tax | Payroll Tax | Employee rate is a flat 1.45% on all gross wages with no annual ceiling or wage limit. |
| Additional Medicare Tax | Payroll Tax (High Earners) | An extra 0.9% applies automatically once an employee's single-employer wages clear $200,000 (Filing thresholds: $200k Single / $250k Joint). |
| Traditional 401(k) / 403(b) | Pre-Tax (Income Tax only) | Reduces current federal taxable income, but does not reduce Social Security or Medicare wages. |
| Health Insurance Premiums | Pre-Tax (If Qualified) | Reduces federal, state, Social Security, and Medicare taxable wages if paid through a qualifying Section 125 plan. |
| HSA / FSA Contributions | Pre-Tax | Reduces taxable income and helps pay for eligible out-of-pocket medical expenses. |
| Roth 401(k) | Post-Tax | Does not reduce current taxable income, but allows qualified tax-free withdrawals later. |
| Union Dues | Post-Tax | Reduces net take-home pay after all taxes have already been calculated. |
| Wage Garnishments | Post-Tax | Withheld from net wages according to legal or court-ordered requirements. |
2026 Retirement Contribution Limits
The IRS annual contribution parameters for retirement accounts are set to the following limits:
Employee Elective Deferrals: For 401(k), 403(b), most 457 plans, and the federal Thrift Savings Plan, the baseline maximum is $24,500.
Standard Catch-Up (Age 50+): Workers age 50 or older can contribute an additional $8,000, making their total limit $32,500.
SECURE 2.0 “Super” Catch-Up (Ages 60–63): Workers who fall within the age bracket of 60 to 63 qualify for an increased catch-up limit of $11,250, bringing their maximum potential elective deferral to $35,750.
High-Earner Catch-Up Mandate: Under SECURE 2.0 rules, if your prior-year FICA wages from your employer exceeded $150,000, all age-50+ catch-up contributions must be made as post-tax Roth contributions (pre-tax catch-up is disabled for these individuals).
Pre-Tax vs Post-Tax: Which Is Better?
Pre-tax deductions are highly beneficial if your primary goal is to lower your current year tax liability and maximize your immediate take-home pay structure. This is common with traditional 401(k) accounts, HSAs, FSAs, and group health premiums.
Post-tax deductions are better when long-term tax optimization matters more than an immediate tax break. Roth 401(k) options allow you to secure tax obligations at today’s rates so your future retirement growth is fully insulated from taxes.
Quick Takeaway
Pre-tax deductions can reduce your current taxable income, while post-tax deductions usually reduce only your final net pay. Use the calculator above to compare how 401(k), HSA, health insurance, and Roth contributions affect your paycheck.
How State and Local Taxes Affect Your Paycheck
Your take-home pay can change significantly depending on where you live and work. Federal income tax, Social Security tax, and Medicare tax apply to most U.S. employees, but state and local income taxes vary by location.
This is why two workers with the same $65,000 salary can receive different net pay depending on their state, city, filing status, deductions, and payroll settings.
Our paycheck calculator estimates your federal tax, state income tax, Social Security, Medicare, and common deductions to help you understand your expected net pay. However, some local taxes may not be included because city and municipal payroll taxes often depend on your exact home or work address.
$65,000 Salary Take-Home Pay Comparison by State
The table below shows how a $65,000 annual salary may translate into estimated take-home pay across different states. These examples assume a single filer with no dependents and no special deductions.
| State / State Group | Estimated State Income Tax | Approx. Annual Take-Home Pay |
|---|---|---|
| Texas, Florida, Washington, Nevada, Wyoming, South Dakota, Tennessee, New Hampshire, Alaska | $0 | About $53,500 |
| Pennsylvania | About $1,600 | About $52,000 |
| Illinois | About $2,600 | About $51,000 |
| New York | About $3,000 | About $50,500 |
| California | About $3,500 | About $50,000 |
These estimates show why state income tax matters when comparing job offers or planning a move. A salary that looks high before taxes may result in a lower paycheck after state and local taxes are withheld.
Why No-Income-Tax States Can Increase Take-Home Pay
States with no income tax may increase take-home pay because no state wage income tax is withheld. However, no-income-tax states are not always cheaper overall because property taxes, sales taxes, housing, insurance, and salary levels can also affect disposable income.
Local Taxes That May Reduce Your Paycheck
In some cities and local areas, you may owe additional local income taxes on top of federal and state taxes. These local payroll taxes can reduce your net pay, even if your state tax estimate looks manageable.
Examples of places with local income taxes include:
| City / Area | Local Tax Note |
|---|---|
| New York City | May charge additional city income tax |
| Philadelphia | Local wage tax may apply |
| St. Louis | Local earnings tax may apply |
| Cincinnati | Municipal income tax may apply |
| Ohio, Pennsylvania, and Michigan cities | Many local areas may have separate city taxes |
Because local taxes can depend on your exact work location, home address, employer setup, or city rules, your actual paycheck may differ from a general state-only estimate. If you live or work in a city with local payroll taxes, review your pay stub or ask your payroll department for confirmation.
Quick State Income Tax Reference
Here is a simple reference to understand how different state tax levels may affect your paycheck:
| State Tax Category | Example States |
|---|---|
| No state income tax | Texas, Florida, Washington, Nevada, Wyoming, South Dakota, Tennessee, New Hampshire, Alaska |
| Lower income tax states | Pennsylvania, Indiana, Arizona, Colorado, Utah, North Dakota |
| Medium income tax states | Illinois, New York, Virginia, Georgia, North Carolina, Michigan |
| Higher income tax states | California, Oregon, Minnesota, New Jersey, Hawaii, Maine |
This reference is useful for quick comparison, but your actual take-home pay depends on more than state tax alone. Filing status, dependents, pre-tax deductions, local taxes, health insurance, retirement contributions, and W-4 settings can all change your final net paycheck.
How to Use This Information
Use the paycheck calculator above to compare your salary in different states before accepting a job offer, moving to a new city, or adjusting your payroll deductions. For the most accurate estimate, enter your gross pay, pay frequency, state, filing status, dependents, and any pre-tax deductions such as 401(k), HSA, or health insurance premiums.
Key takeaway: State and local taxes can make a major difference in your take-home pay, but they are only one part of the full paycheck picture. Always compare net pay, cost of living, benefits, and local tax rules before making a financial decision.
Real Example Calculation — See Exactly How It Works
Let us walk through a real example step by step. You will see exactly how your gross pay becomes net pay after all federal taxes, state taxes, and payroll deductions are applied.
The Example Scenario: Meet Sarah
To understand the math, let’s look at Sarah’s financial profile for the 2026 tax year:
Annual Salary: $65,000
Pay Frequency: Biweekly (26 paychecks per year)
Filing Status: Single (0 dependents)
Location: Texas (No state income tax)
Pre-Tax Deductions: 5% 401(k) contribution + $120 health insurance per paycheck
Sarah’s Paycheck At A Glance
If you are in a hurry, here is the quick breakdown of Sarah’s biweekly paycheck stub:
Gross Pay: $2,500.00
Pre-Tax Deductions: -$245.00
Federal Income Tax: -$186.75
FICA Taxes (Social Security & Medicare): -$191.25
State Income Tax: -$0.00
Take-Home Net Pay: $1,877.00
Detailed Step-by-Step Breakdown
Step 1: Calculate Gross Pay Per Paycheck
Sarah earns a flat $65,000 per year and gets paid every two weeks. To find her base gross pay per paycheck, we divide her annual salary by her total yearly pay periods.
The Math: $65,000 annual salary ÷ 26 pay periods
Sarah’s Gross Pay: $2,500.00
Step 2: Deduct Pre-Tax Benefits
Sarah contributes to a traditional 401(k) and pays for health insurance. Because these are pre-tax deductions, they are subtracted directly from her gross pay before federal income taxes are calculated.
401(k) Contribution (5% of Gross): $2,500 × 0.05 = $125.00
Health Insurance Premium: $120.00
Total Pre-Tax Deductions: $125 + $120 = $245.00
Step 3: Determine Taxable Gross Pay
Taxable gross pay is the actual amount of income subject to federal tax withholding. We find this by removing the pre-tax deductions from her initial gross pay.
The Math: $2,500 Gross Pay – $245 Pre-Tax Deductions
Sarah’s Taxable Gross Pay: $2,255.00
Step 4: Calculate 2026 Federal Income Tax Withholding
To find the exact federal withholding, the payroll system projects her paycheck over the entire year and applies the official 2026 IRS tax updates:
Annualized Taxable Income: Multiply her $2,255 taxable paycheck by 26 pay periods to get $58,630.
Apply 2026 Standard Deduction: Subtract the updated $16,100 standard deduction for single filers. This leaves her with an actual taxable income base of $42,530.
Apply Progressive Tax Brackets:
10% Bracket: 10% on the first $12,400 = $1,240.00
12% Bracket: 12% on the remaining income ($42,530 – $12,400 = $30,130) = $3,615.60
Total Annual Federal Tax: $1,240 + $3,615.60 = $4,855.60
Per Paycheck Federal Tax: Divide the annual tax by 26 pay periods ($4,855.60 ÷ 26) = $186.75
Step 5: Account for State Income Tax
Since Sarah lives and works in Texas, her state tax calculation is simple. Texas is one of the states that does not impose a local income tax.
Sarah’s State Income Tax: $0.00
Step 6: Calculate FICA Taxes Social Security & Medicare
FICA taxes are statutory payroll taxes. Unlike federal income tax, FICA is calculated using Sarah’s total gross pay ($2,500). Pre-tax deductions do not lower your FICA tax baseline.
Social Security (6.2% of Gross): $2,500 × 0.062 = $155.00
Medicare (1.45% of Gross): $2,500 × 0.0145 = $36.25
Total FICA Withholding: $155 + $36.25 = $191.25
Step 7: Calculate Final Net Take-Home Pay
To find Sarah’s final take-home pay, we take her initial gross paycheck and strip away all taxes and benefit costs.
The Formula: $2,500 Gross Pay – $245 Pre-Tax – $186.75 Federal Tax – $0 State Tax – $191.25 FICA Taxes
Sarah’s Final Net Pay: $1,877.00
Takeaway for Users: By optimizing your pre-tax retirement accounts (like Sarah’s 401k), you successfully lower your taxable gross income base, saving money on federal income taxes while building your future wealth. Use our automated paycheck calculator above to input your own deductions and instantly see your updated take-home pay.
Why Your Actual Paycheck May Not Match the Calculator
A paycheck calculator gives an estimate based on the information you enter, but your actual paycheck may be different because your employer’s payroll system uses exact payroll records, benefit settings, state registrations, local taxes, Form W-4 details, overtime rules, bonus treatment, and pay-period timing.
This does not always mean the calculator is wrong. In many cases, the difference happens because your pay stub includes employer-specific deductions, local payroll rules, or details that a general calculator may not know.
Common Reasons Your Paycheck May Be Different
| Paycheck Problem | Why It Happens | What to Check |
|---|---|---|
| Your paycheck is lower than expected | Local taxes, insurance premiums, benefit deductions, retirement contributions, or extra W-4 withholding may reduce your net pay. | Check your pay stub, Form W-4, benefit deductions, and local tax lines. |
| You moved or worked in another state | Payroll may need to withhold tax based on the state where you physically worked, not only your home address. | Check your work location, resident state, reciprocity rules, and payroll address. |
| Overtime looks taxed too high | A larger paycheck can cause higher withholding for that pay period, even though overtime is generally taxed as regular income overall. | Compare regular wages, overtime hours, taxable wages, and federal withholding. |
| Bonus withholding looks higher than expected | Bonuses may be treated as supplemental wages, so withholding can look different from your regular paycheck. | Check whether the bonus was paid separately or combined with regular wages. |
| Your 401(k) did not reduce FICA tax | Traditional 401(k) contributions usually reduce federal taxable income, but they generally do not reduce Social Security or Medicare wages. | Compare federal taxable wages with Social Security and Medicare wages on your pay stub. |
| Health benefits changed your paycheck more than expected | Some health insurance, HSA, FSA, dental, or vision deductions may reduce taxable wages depending on how the plan is set up. | Review your benefit elections and pre-tax deduction lines. |
| Direct deposit says paid, but money is missing | Wrong bank details, rejected deposits, bank delays, or payroll processing issues can affect when funds arrive. | Contact payroll and your bank immediately with the pay date and deposit details. |
| Your paycheck was adjusted after an overpayment | Employers may correct a previous overpayment or underpayment in a later payroll cycle. | Ask payroll for a written breakdown of the correction. |
| Your pay stub state does not match your real work state | Your employer may have updated your home address but not your worked-in state or payroll tax location. | Check state withholding, work location, SUI setup, and payroll records. |
| The calculator does not include your exact city tax | Some city, county, or local taxes depend on your exact home or work address. | Review your local tax line on your pay stub or ask payroll for confirmation. |
What to Do If Your Paycheck Does Not Match
If your actual paycheck is different from the calculator result, start by comparing your pay stub line by line. Look at your gross pay, taxable wages, federal withholding, state withholding, Social Security, Medicare, benefit deductions, retirement contributions, and net pay.
Then check whether your Form W-4, pay frequency, filing status, dependents, work state, local taxes, and deductions match what you entered into the calculator.
Key Takeaway
A paycheck calculator is a planning tool, while your employer’s payroll system uses your exact payroll profile. Your actual net pay may differ because of local taxes, W-4 settings, benefit deductions, overtime, bonuses, payroll corrections, or state-specific rules. For the most accurate review, compare the calculator result with your official pay stub.
Common Mistakes to Avoid When Calculating Your Paycheck
Estimating your paycheck seems simple, but small mistakes can lead to an inaccurate take-home pay estimate. Your net pay can change because of overtime, W-4 settings, pre-tax deductions, state taxes, local taxes, bonuses, and payroll timing. Avoiding these common paycheck calculation mistakes can help you plan your budget more accurately and reduce the chance of a surprise tax bill.
Mistake 1: Thinking Overtime Is Taxed at a Special Permanent Rate
Overtime is not taxed under a separate permanent tax rate. It is included in your total taxable wages for the year and taxed through the regular federal income tax system.
Your overtime paycheck may look like it was taxed more heavily because payroll systems often withhold more from a larger paycheck. However, your final tax liability is based on your total annual income, filing status, deductions, credits, and tax brackets. If too much was withheld, it may be adjusted when you file your tax return.
Mistake 2: Not Updating Your Form W-4 After Life Changes
Your Form W-4 tells your employer how much federal income tax to withhold from each paycheck. If your personal or financial situation changes, your old W-4 may no longer match your actual tax situation.
You should review your W-4 after major changes such as marriage, divorce, having a child, starting a second job, your spouse starting or leaving work, or a major income change. IRS Form W-4 guidance says employees should complete a new W-4 when personal or financial changes affect the entries on the form.
Mistake 3: Ignoring Pre-Tax Deductions
Pre-tax deductions can change your paycheck estimate because they may reduce your taxable income before federal and state income taxes are calculated.
Common pre-tax deductions include traditional 401(k) contributions, HSA contributions, FSA contributions, and qualifying health insurance premiums. If you leave these out of your estimate, your paycheck calculation may show higher taxes than your employer actually withholds.
However, not all pre-tax deductions affect every tax the same way. For example, traditional 401(k) contributions usually reduce federal taxable income, but they generally do not reduce Social Security or Medicare wages.
Mistake 4: Confusing Marginal Tax Rate With Effective Tax Rate
Your marginal tax rate is the rate applied to your next dollar of taxable income. Your effective tax rate is your average tax rate across all taxable income.
For example, being in the 22% federal tax bracket does not mean your entire income is taxed at 22%. Part of your income may be taxed at lower rates first. This is why your effective tax rate is usually lower than your top marginal tax rate.
Understanding this difference helps you avoid overestimating your paycheck taxes.
Mistake 5: Forgetting State and Local Taxes
Federal taxes are only one part of your paycheck. State and local income taxes can also reduce your take-home pay.
Some states have no state income tax, while others have flat or progressive income tax systems. Some cities and local areas may also charge local income taxes. If your paycheck calculator only estimates federal tax and FICA, your final take-home pay may be different.
Always check whether your state, city, or local area has additional payroll taxes before relying on a paycheck estimate.
Mistake 6: Assuming a 401(k) Contribution Reduces Net Pay Dollar-for-Dollar
A traditional 401(k) contribution usually reduces your taxable income for federal income tax purposes. Because of that tax benefit, your take-home pay may decrease by less than the actual contribution amount.
For example, if you contribute an extra $25 per paycheck to a traditional 401(k), your net pay may drop by less than $25 because part of the contribution may reduce your federal income tax withholding.
Roth 401(k) contributions work differently. They are usually post-tax, so they do not reduce your current taxable income.
Mistake 7: Not Reviewing Your Pay Stub Regularly
Your pay stub shows how your employer calculated your paycheck. It includes gross pay, federal tax, state tax, Social Security, Medicare, benefit deductions, retirement contributions, year-to-date totals, and net pay.
Review your pay stub after a raise, bonus, job change, benefits update, W-4 change, or new deduction. If your actual paycheck does not match your estimate, your pay stub can help you find the reason.
Mistake 8: Misunderstanding Bonus Pay Withholding
Bonuses are often treated as supplemental wages for withholding purposes. A bonus may have federal income tax withheld at a flat supplemental wage rate, which can make the withholding look higher than a regular paycheck.
For 2026, IRS Publication 15 states that the withholding rate on supplemental wages remains 22%, with a 37% rate applying when supplemental wages paid to an employee exceed $1 million during the calendar year.
This does not always mean your final tax rate on the bonus is exactly 22%. Your final tax is based on your full annual tax return.
Mistake 9: Not Using the IRS Tax Withholding Estimator for Complex Situations
A basic paycheck calculator is helpful for quick estimates, but complex situations may need a deeper review. This includes multiple jobs, spouse income, large bonuses, self-employment income, dependents, itemized deductions, or major tax credits.
The IRS Tax Withholding Estimator can help taxpayers decide whether they should adjust withholding and generate a pre-filled Form W-4 if changes are needed.
Quick Checklist to Avoid Paycheck Calculation Errors
Before relying on your paycheck estimate, check these items:
- Confirm your gross pay, hourly rate, salary, or overtime hours.
- Select the correct pay frequency.
- Use the correct filing status.
- Include dependents and tax credits if applicable.
- Add traditional 401(k), HSA, FSA, and health insurance deductions.
- Check whether your state or city has income tax.
- Review your W-4 after major life changes.
- Compare your estimate with your actual pay stub.
- Recalculate after a raise, bonus, job change, or benefits update.
Key Takeaway
A paycheck calculator is most useful when your inputs are accurate. Overtime, bonuses, W-4 settings, pre-tax deductions, state taxes, local taxes, and benefit deductions can all change your final take-home pay. Use the calculator above as a planning tool, then compare the result with your actual pay stub for the most accurate picture.
How to Read Your Pay Stub and Understand Your Paycheck
Your paycheck shows the money you receive, but your pay stub explains how that amount was calculated. Understanding your pay stub helps you verify your earnings, check tax withholding, review deductions, and catch payroll mistakes before they affect your budget.
A paycheck is the actual payment you receive from your employer. It may come as a paper check or direct deposit into your bank account. The main number most people look at is net pay, which is the amount you actually take home.
A pay stub is the detailed breakdown behind that payment. It shows your gross pay, taxes withheld, benefit deductions, retirement contributions, year-to-date totals, and final net pay. If your paycheck looks lower or higher than expected, your pay stub is the first place to check.
Pay Stub Line Items Explained
| Pay Stub Line Item | What It Means | Why It Matters |
|---|---|---|
| Gross Pay | Your total earnings before taxes and deductions. This may include salary, hourly wages, overtime, bonuses, commissions, or holiday pay. | This is the starting point for your paycheck calculation. |
| Federal Income Tax Withholding | The amount your employer withholds for federal income tax based on your Form W-4, taxable income, filing status, pay frequency, and federal tax brackets. | If this is too low, you may owe tax when filing. If it is too high, you may receive a larger refund but lower take-home pay during the year. |
| State Income Tax Withholding | The amount withheld for state income tax. This varies by state, and some states do not charge state income tax on wages. | State tax can significantly change your take-home pay depending on where you live or work. |
| Social Security Tax | A payroll tax withheld from wages to fund Social Security. For 2026, employees pay 6.2% on wages up to the $184,500 Social Security wage base. | Once your year-to-date wages pass the annual wage base, Social Security withholding usually stops for the rest of the year. |
| Medicare Tax | A payroll tax withheld from wages to help fund Medicare. Standard Medicare tax is 1.45% on covered wages, with no regular wage base limit. | Unlike Social Security, Medicare tax generally applies to all covered wages. Higher earners may also owe Additional Medicare Tax. |
| Additional Medicare Tax | An extra 0.9% Medicare tax may apply when wages exceed certain thresholds, such as $200,000 for single filers. | This can reduce take-home pay for high earners once income passes the threshold. |
| Pre-Tax Deductions | Deductions taken before certain taxes are calculated, such as traditional 401(k), HSA, FSA, or qualifying health insurance premiums. | These may lower taxable income and reduce current tax withholding. |
| Post-Tax Deductions | Deductions taken after taxes, such as Roth 401(k), union dues, charitable payroll deductions, or wage garnishments. | These reduce net pay but usually do not reduce current taxable income. |
| Year-to-Date Totals | Running totals from January 1 through the current paycheck for wages, taxes, and deductions. | YTD totals help you check whether annual limits, tax withholding, and benefit deductions are being tracked correctly. |
| Net Pay | The final amount you receive after taxes and deductions. | This is your actual take-home pay and the number you should use for budgeting. |
How to Check Your Pay Stub for Errors
Review your pay stub at least once a quarter, and always check it after a raise, bonus, job change, benefits change, or W-4 update. Make sure your gross pay, hours worked, overtime, tax filing status, retirement contribution, health insurance premium, and net pay look correct.
If your paycheck does not match your estimate from the paycheck calculator, the difference may come from W-4 settings, local taxes, employer benefits, insurance premiums, overtime, bonuses, post-tax deductions, or payroll timing.
Quick Pay Stub Checklist
Before you accept your paycheck as correct, check these items:
- Your gross pay matches your salary, hourly rate, or hours worked.
- Your federal withholding matches your Form W-4 settings.
- Your state withholding matches your work or residence state rules.
- Your Social Security tax stops after the annual wage base is reached.
- Your Medicare tax continues because it has no regular wage cap.
- Your pre-tax and post-tax deductions are listed correctly.
- Your year-to-date totals look accurate.
- Your net pay matches what was deposited into your account.
Key Takeaway
Your paycheck tells you how much money you received, but your pay stub tells you why you received that amount. Use your pay stub with the paycheck calculator above to compare gross pay, taxes, deductions, and net pay. If something looks wrong, contact your payroll or HR department for clarification.
FICA, Social Security and Medicare Taxes in 2026
FICA taxes are mandatory U.S. payroll taxes that help fund Social Security and Medicare. Unlike federal income tax, which uses progressive tax brackets, FICA taxes are usually calculated as a fixed percentage of wages.
For most employees, FICA has two main parts:
- Social Security tax
- Medicare tax
Your employer withholds these taxes from each paycheck and also pays an employer share. If you are self-employed, you generally pay both the employee and employer portions through self-employment tax.
Social Security Tax in 2026
For the 2026 tax year, employees pay 6.2% Social Security tax on wages up to the annual Social Security wage base.
The 2026 Social Security wage base is $184,500. This means only the first $184,500 of covered wages is subject to Social Security tax. Once your year-to-date wages pass this limit, Social Security withholding usually stops for the rest of the year. The maximum employee Social Security tax for 2026 is $11,439.00.
Medicare Tax in 2026
Medicare tax works differently from Social Security tax. Employees generally pay 1.45% Medicare tax on covered wages, and there is no regular annual wage cap. This means Medicare tax continues even after your income passes the Social Security wage base.
For example, if you earn $250,000 in wages, Social Security tax applies only up to the 2026 wage base, but Medicare tax generally applies to the full covered wage amount.
Additional Medicare Tax for Higher Earners
Some higher earners may also owe an extra 0.9% Additional Medicare Tax. This tax applies only to income above certain thresholds.
| Filing Status | Additional Medicare Tax Threshold |
|---|---|
| Single | Over $200,000 |
| Married Filing Jointly | Over $250,000 |
| Married Filing Separately | Over $125,000 |
You only pay the additional 0.9% Medicare tax on income above the threshold, not on your full income.
Example: If you are single and earn $220,000, the extra 0.9% Medicare tax applies only to the $20,000 above $200,000. That equals $180 in Additional Medicare Tax.
Employers must begin withholding Additional Medicare Tax once an employee’s wages exceed $200,000 in a calendar year, regardless of filing status or spouse income.
Do Pre-Tax Deductions Reduce FICA Taxes?
Not all pre-tax deductions reduce FICA taxes in the same way.
Traditional 401(k) contributions generally reduce federal taxable income, but they usually do not reduce Social Security or Medicare wages.
Qualified health insurance premiums under a Section 125 cafeteria plan may reduce federal income tax, state income tax, Social Security tax, and Medicare tax wage bases. This is why two deductions with the same dollar amount can affect your paycheck differently.
FICA Tax Quick Reference for 2026
| Payroll Tax | Employee Rate | 2026 Wage Limit | Notes |
|---|---|---|---|
| Social Security Tax | 6.2% | $184,500 | Stops after wage base is reached |
| Medicare Tax | 1.45% | No regular wage cap | Applies to covered wages |
| Additional Medicare Tax | 0.9% | Applies above threshold | For higher earners |
| Self-Employment Social Security | 12.4% | $184,500 | Self-employed workers pay both shares |
| Self-Employment Medicare | 2.9% | No regular wage cap | Additional Medicare Tax may also apply |
How FICA Taxes Affect Your Paycheck
FICA taxes directly reduce your take-home pay. For a regular employee, Social Security and Medicare are withheld from each paycheck before you receive your net pay.
For example, if your gross paycheck is $2,500, your standard employee FICA withholding would be:
- Social Security: $2,500 × 6.2% = $155.00
- Medicare: $2,500 × 1.45% = $36.25
- Total FICA withholding: $191.25
This amount is separate from federal income tax, state income tax, retirement contributions, health insurance premiums, and other paycheck deductions.
Key Takeaway
FICA taxes are an important part of every paycheck calculation. Social Security tax applies at 6.2% up to the 2026 wage base of $184,500, while Medicare tax applies at 1.45% with no regular wage cap. Higher earners may also owe an extra 0.9% Additional Medicare Tax above the applicable income threshold.

W-4 Form Guide — How to Fill It Out Correctly
Your Form W-4 helps your employer estimate how much federal income tax to withhold from each paycheck. Filling it out with high precision prevents you from facing underpayment penalties or giving the government an unnecessary interest-free loan.
Step-by-Step Breakdown of Form W-4
Step 1 — Personal Information & Filing Status Log your exact legal name, matching address, Social Security Number (SSN), and true tax filing status (Single, Married Filing Jointly, or Head of Household). Ensure your name matches your physical Social Security card exactly to avoid processing delays.
Step 2 — Multiple Jobs or Working Spouse If you hold multiple jobs concurrently, or if you are married and your spouse works, you must account for this here. Check the checkbox in Step 2(c) on both W-4 forms, or use an advanced automated payroll calculator to cross-reference your household’s total progressive tax brackets.
Step 3 — Claiming Dependents & Credits For the 2026 tax year, you can claim direct tax credits to reduce your paycheck withholding:
Qualifying children under the age of 17: Multiply the number of children by $2,000.
Other eligible dependents: Multiply the number of dependents by $500.
Implementation: Tally the totals and enter the final dollar sum on Line 3 to directly lower your per-paycheck withholding footprint.
Step 4 — Custom Deductions & Adjustments
Line 4(a) (Other Income): Input outside, un-withheld income streams like investment dividends, interest earnings, or independent side jobs so you don’t face tax surprises.
Line 4(b) (Deductions): Enter estimated deductions here if you plan to bypass the standard deduction ($16,100 for Single / $32,200 for Joint filers in 2026) in favor of itemizing your write-offs.
Line 4(c) (Extra Withholding): Enter an extra dollar amount you want your employer to withhold from each paycheck.
Step 5 — Authorize & Sign Your Form W-4 is completely invalid without a physical or verified digital signature. Sign and date the document before delivering it directly to your company’s HR or payroll administrator.
When to Formally Update Your W-4
Do not file your W-4 just once and forget about it. To prevent major tax gaps, you are legally or strategically advised to update your withholding certificate within 30 days of encountering these life-change milestones:
Marital Status Shifts: Getting married or finalized updates following a divorce.
Family Infrastructure Updates: Having a baby, legally adopting a child, or losing a dependent credit.
Multi-Income Adjustments: Accepting a secondary job, launching a business, or your spouse starting/stopping a career.
Real Estate Assets: Purchasing a primary home if you intend to write off qualifying itemized mortgage interest rates.
Income Fluctuations: Experiencing a massive spike or drop in your standard annual base earnings.
Frequently Asked Questions
Here are answers to the most common questions about paycheck calculations, taxes, and deductions.
In 2026, these 9 states have zero state income tax on your paycheck:
Alaska
Florida
Nevada
New Hampshire
South Dakota
Tennessee
Texas
Washington
Wyoming
A good starting point is to contribute enough to receive your full employer match, if available. Many workers aim to save 10% to 15% of income for retirement, but the right amount depends on your budget, income, employer match, tax situation, and retirement goals.
The standard deduction reduces the amount of income you pay taxes on. For 2026, the amounts are:
Single: $16,100
Married Filing Jointly: $32,200
Head of Household: $24,150
Marginal Tax Rate: This is your tax bracket. It is the percentage of tax you pay on your very last dollar of income.
Effective Tax Rate: This is your actual average tax rate. It is the total tax you pay divided by your total income. It is always lower than your marginal rate because your first dollars are taxed at lower percentages.
Overtime pay is taxed as regular income.
When you work overtime, your paycheck is larger. The payroll system looks at that single large check and estimates your yearly income is higher, so it holds back a larger percentage of tax for that specific pay period.
You receive all extra tax withholdings back at the end of the year as a tax refund when you file your tax return.
Tax rules look at two specific locations: where you live and where you do the work.
The Work Location Rule: You owe income tax to the state where you physically perform the work. If you travel to a different state for work, you file a return there, and your home state gives you a tax credit to prevent you from paying twice.
State Agreements: Some neighboring states have agreements where you only pay tax to your home state.
The Remote Work Rule (Latest Update): If you work from home for a company located in states like New York, New Jersey, or Pennsylvania, that state can tax your income unless your company strictly requires you to work from home for business reasons.
Your actual paycheck may differ because of Form W-4 settings, local taxes, employer benefits, health insurance, retirement deductions, overtime, bonuses, garnishments, pay-period timing, or employer payroll rules.
Your paycheck may depend on where you physically perform the work, your resident state, employer registration, reciprocity rules, and local taxes. Remote workers should confirm their work location with payroll.
Overtime is not taxed at a special permanent rate. A larger paycheck may cause higher withholding for that pay period, but final tax depends on total annual income and your tax return.
Bonuses are often treated as supplemental wages. Federal withholding may be applied differently from regular wages, but your final tax depends on your annual income, deductions, credits, and filing status.
Check your pay stub first, then contact payroll or HR with the pay date, gross pay, net pay, deduction lines, and bank deposit issue. If direct deposit details are wrong, contact payroll and your bank immediately.
