How to Actually Read Your Pay Stub : Every Deduction Explained for 2026
Hello, I'm Jenie!
Most people look at one number on their pay stub : the deposit amount at the bottom. Everything above it is a blur of abbreviations like FITW, OASDI, and YTD that nobody explains when you start a new job. Here's the thing nobody tells you : those abbreviations are taking a meaningful chunk of your paycheck, and understanding exactly what they are is the first step to making smarter decisions about your withholding, your benefits, and your tax return.
This guide walks through every line on a standard U.S. pay stub, using 2026 rates and real numbers, so the next time you open yours it takes 90 seconds to verify everything looks right.

1. The Three Numbers That Matter Most
Before getting into the detail of every line, start with three numbers every time you open your pay stub.
Gross pay : The total you earned this period before anything is taken out. Verify it matches your salary divided by your number of pay periods, plus any overtime, bonuses, or commissions.
Total taxes : The sum of everything withheld for federal, state, and FICA taxes. Does it feel roughly right based on your W-4 and income level?
Net pay : The actual deposit. Does this match what hit your bank account?
If all three look right, the rest is detail work. If any one of them is off, that's where to start investigating.
2. Gross Pay : Where It All Starts
Gross pay is your total compensation before any deductions. For salaried employees, it's your annual salary divided by the number of pay periods. A $60,000 annual salary paid biweekly yields a gross pay of $2,307.69 per check (26 pay periods per year).
What gets added to gross pay : ◦ Regular wages or salary ◦ Overtime pay (typically 1.5x your regular rate) ◦ Bonuses and commissions ◦ Tips (if applicable)
What to verify : Multiply your per-check gross by the number of paychecks you've received this year. Does it match your year-to-date gross? If not, your employer may have underpaid you at some point and it's worth flagging to HR.
3. Federal Income Tax (FITW) : The Big One
You'll see this labeled as FITW, FIT, FED W/H, FWT, or Federal Withholding depending on your employer's payroll software. They all mean the same thing : the federal income tax your employer withholds each pay period and sends directly to the IRS on your behalf.
How it's calculated : Your employer uses the information from your W-4 form combined with the 2026 IRS tax tables. The 2026 federal income tax system uses seven progressive brackets : 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Only the portion of your income that falls within each bracket is taxed at that rate.
2026 quick example : An employee earning $50,000 annually who files single with standard deduction might see around $625 withheld per month in federal tax, roughly 15% of gross pay. The actual rate varies based on their specific W-4 elections.
W PayStub Directhy your withholding might be wrong : ◦ You got married, had a child, or got divorced and didn't update your W-4 ◦ You started a side business with additional income not covered by payroll withholding ◦ You're working two jobs and neither employer knows about the other
If you owed a large amount at tax time last year, or received a large refund, your withholding is probably miscalibrated. Use the IRS Withholding Estimator at irs.gov to recalculate and submit a new W-4 to your employer.
4. FICA : Social Security and Medicare
FICA stands for Federal Insurance Contributions Act. It funds two programs : Social Security retirement and disability benefits, and Medicare health coverage. Unlike federal income tax, FICA is not based on your W-4. It applies at a fixed rate to everyone.
2026 FICA rates :
- Social Security (labeled OASDI or SS on your stub) : 6.2% of gross wages up to the wage base limit of $184,500 for 2026. Once OnPay your year-to-date earnings hit that threshold, Social Security withholding stops for the rest of the year. High earners notice a sudden increase in take-home pay when this happens, usually around mid to late year.
- Medicare (labeled MED or Medicare) : 1.45% of all wages with no cap. Every dollar you earn is subject to Medicare tax. Earn over $200,000 as a single filer ($250,000 married filing jointly) and an additional 0.9% Medicare surtax applies above that threshold.
- Your employer's contribution : Your employer matches your FICA contribution dollar for dollar : 6.2% Social Security and 1.45% Medicare. This employer contribution doesn't appear on your pay stub because it never comes from your paycheck. It's an additional cost your employer pays on your behalf.
Total FICA for most employees : 7.65% of every paycheck.
The self-employment comparison : If you have a side business, you pay both the employee and employer portions of FICA, which is 15.3% total, through self-employment tax. This is why having self-employment income on top of a salaried job significantly increases your overall tax burden.
5. State and Local Income Tax
State tax withholding depends entirely on where you work, not where you live (though reciprocal agreements between states complicate this for some employees).
Key facts for 2026 : ◦ Nine states have no income tax : Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you work in one of these states, this line won't appear on your stub. ◦ State tax rates for 2026 range from 0% to over 13% depending on location and income level. Some states use flat rates (Illinois charges everyone 4.95%). Others use progressive brackets like the federal system. California tops out above 13% for high earners. ◦ Lo PayStub Directcal income taxes apply in some cities and counties (New York City, Philadelphia, certain Ohio municipalities). These appear as a separate line item labeled City Tax, Local Tax, or similar.
6. Pre-Tax Deductions : The Lines That Reduce Your Tax Bill
Pre-tax deductions are taken out of your gross pay before taxes are calculated. This means they reduce the income on which you're taxed, effectively giving you an immediate tax benefit.
Common pre-tax deductions :
- 401(k) contributions : Your retirement contributions come out before federal and state income tax is calculated. If you contribute $500 per paycheck and you're in the 22% federal bracket, you're saving approximately $110 in federal taxes on that contribution alone.
- Health insurance premiums : Employer-sponsored health insurance premiums are typically deducted pre-tax under a Section 125 cafeteria plan. You're paying for coverage before taxes touch that money.
- HSA contributions : Health Savings Account contributions are triple-tax advantaged : pre-tax going in, tax-free growth, tax-free withdrawals for qualified medical expenses.
- FSA contributions : Flexible Spending Account contributions work similarly to HSAs but with use-it-or-lose-it rules.
- Dental and vision premiums : Usually pre-tax under the same cafeteria plan structure as health insurance.
The practical impact : A $60,000 gross salary with $5,000 in annual 401(k) contributions and $3,000 in health insurance premiums means your federal income tax is calculated on $52,000, not $60,000. That difference is real money.
7. Post-Tax Deductions
Post-tax deductions come out after taxes are calculated. They don't reduce your taxable income, but they do reduce your net pay.
Common post-tax deductions : ◦ Roth 401(k) contributions (contributions are post-tax, but growth and qualified withdrawals are tax-free) ◦ Life insurance premiums above certain thresholds ◦ Garnishments (court-ordered wage deductions for debt repayment or child support) ◦ Union dues ◦ Some disability insurance premiums
8. Net Pay : What You Actually Take Home
Net pay is gross pay minus all deductions : federal tax, state tax, FICA, pre-tax benefits, and post-tax deductions. This is the number that hits your bank account.
A quick check : For a salaried employee earning $60,000 per year in a state with average taxes, gross pay per biweekly check is approximately $2,308. After federal and state income tax, FICA, and standard benefit deductions, a reasonable estimate for net pay might be $1,600 to $1,750 per check. If your net pay looks significantly lower, audit your pre-tax and post-tax deductions to make sure everything is correct and authorized.
9. Year-to-Date (YTD) : Why This Column Matters More Than You Think
The YTD column shows running totals for everything since January 1. Most people ignore it. That's a mistake.
What to check in your YTD column :
- YTD gross vs. expected : Multiply your per-check gross by the number of checks you've received. Does it match? A discrepancy could indicate a missed bonus, an incorrect salary adjustment, or a payroll error.
- YTD federal withholding : Divide your YTD federal withholding by your YTD gross. Is the effective rate reasonable for your income and filing status? If it's too low, you may owe at tax time. Too high means you're giving the IRS an interest-free loan.
- Social Security YTD : Once your YTD gross hits $184,500 in 2026, Social Security withholding should stop. If it continues past that point, your employer is over-withholding and you're entitled to a refund (through your tax return, not directly from your employer).
10. The Most Common Pay Stub Errors and How to Catch Them
Pay stub errors happen more frequently than most employees realize. Here are the ones worth checking for :
Wrong pay rate : After a raise, promotion, or job change, verify that your new rate is reflected in the first paycheck following the effective date. Payroll systems sometimes lag by a pay period.
Incorrect tax withholding : If you submitted a new W-4 after a life change, verify the updated withholding amount appears on the next check.
Missing or incorrect benefit deductions : When you enroll in or change health insurance during open enrollment, confirm the new premium amount shows up correctly.
Continued Social Security withholding above the wage cap : As noted above, once you hit $184,500 in 2026, Social Security should stop. If it doesn't, flag it with payroll.
Double deductions : Rare but it happens. If a deduction appears twice in one pay period, it's likely a payroll system error.
The habit that prevents most problems : Review your pay stub for five minutes once a month. Check gross, total taxes, and net against what you expect. Cross-reference your YTD gross against your own calculation every quarter. Most errors are caught quickly when you're looking for them and go undetected for months when you're not.
