To calculate your year-to-date income from a pay stub, look at the “YTD” or “Year-to-Date” column and find the gross pay line: that figure is your total earnings from January 1 through the current pay period, before any deductions. If you want to check it yourself, multiply your gross pay per period by the number of paychecks with check dates falling in the current calendar year. The two numbers should match within a few dollars.
That is the whole calculation when your pay is steady. Most of the work in getting an accurate figure is knowing which number on the stub to trust, what to add when your earnings vary, and why the gross on your stub will not match the wages that eventually show up on your W-2.
The Numbers to Pull Off the Stub
A standard pay stub runs two parallel columns. “Current” (sometimes “This Period”) shows what you earned and what was withheld for the single pay period in front of you. “YTD” shows the running totals since January 1. Both columns break out the same line items, so current-period gross sits alongside cumulative gross, current federal tax withheld sits alongside total federal tax withheld, and so on.
Four fields matter for the calculation:
- Current gross pay: your earnings for the pay period before any deductions.
- YTD gross pay: the running total your employer has already calculated.
- Pay period end date: the last day of the work period the paycheck covers.
- Check date (or pay date): the date the payment is actually issued.
The last two fields matter more than they look at year-end. Under IRS rules, income is taxable in the year you “actually or constructively receive” it, meaning the year the check is made available to you, not the year you performed the work.1Internal Revenue Service. Publication 17 (2025), Your Federal Income Tax A paycheck for work done December 16–31 that isn’t issued until January 5 counts as next year’s income. If your employer made the check available on December 31 but you didn’t pick it up until January, it still counts as the earlier year.2Office of the Law Revision Counsel. 26 USC 451 – General Rule for Taxable Year of Inclusion Use the check date, not the pay period end date, to decide whether a given paycheck belongs in this year’s YTD.
The Basic Calculation
If your gross pay is the same every period, multiply that gross by the number of paychecks received so far this year. The number of pay periods in a full year depends on your employer’s schedule:
- Weekly: 52 per year
- Biweekly (every two weeks): 26 per year
- Semimonthly (twice a month): 24 per year
- Monthly: 12 per year
Count the paychecks with check dates between January 1 and today. Paid biweekly at $2,500 gross per check, with 14 checks received, your YTD gross is $35,000. Compare that to the YTD gross field on your latest stub. If they match, you have your number.
When they don’t, one of the situations below usually explains the gap.
When Your Earnings Vary
Simple multiplication breaks down as soon as overtime, bonuses, or commissions enter the picture, because those pieces don’t appear in every paycheck.
Overtime
Federal law requires employers to pay non-exempt workers at least one and a half times their regular hourly rate for every hour beyond 40 in a workweek.3U.S. Department of Labor. Fact Sheet 23 – Overtime Pay Requirements of the FLSA If your overtime hours vary from week to week, no single paycheck represents your average, and multiplying one stub by the number of periods will miss. Add up gross pay from each stub individually, or just use the YTD gross printed on your most recent one. Employer payroll portals usually keep a full history if you’re missing stubs.
Bonuses
A one-time bonus counts toward your YTD gross regardless of how it was withheld. Employers typically withhold federal income tax on bonuses at a flat 22%, and at 37% on supplemental wages exceeding $1 million in the calendar year.4Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide The higher withholding rate affects only the net amount deposited in your account. Use the pre-withholding bonus figure when calculating YTD income.
Bonuses your employer promises in advance or ties to production targets are “non-discretionary” and must be included in your regular rate for overtime purposes.5eCFR. 29 CFR 778.211 – Discretionary Bonuses If you worked overtime during a period that also carried a non-discretionary bonus, your overtime pay for that period should be slightly higher than plain time-and-a-half.
Commissions
Commissions appear as part of gross pay, often on their own line. Some employers pay them on a different cycle from base salary, so a commission can arrive a month or two after the sale closed. For YTD purposes, a commission counts when the check is issued, not when the deal was closed.
Why Gross YTD and Taxable YTD Are Different Numbers
The YTD gross on your stub is everything your employer paid you. The wages that will eventually appear in Box 1 of your W-2 are that gross minus certain pre-tax deductions. Lenders usually want the gross. The IRS cares about Box 1.6Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) Knowing which one is being asked for prevents a lot of confusion.
Retirement Contributions
Traditional 401(k) contributions are excluded from your taxable income, so they lower the wages reported in Box 1 of your W-2 but do not lower your YTD gross.7Internal Revenue Service. 401(k) Plans If you contribute $1,000 per biweekly paycheck, your YTD gross keeps its full value; your YTD taxable wages run $1,000 lower each period.
Health Insurance and HSA Contributions
Premiums for employer-sponsored health insurance paid through payroll are generally excluded from federal income tax, Social Security tax, and Medicare tax.8Internal Revenue Service. Employee Benefits Health Savings Account contributions work similarly. These reduce both taxable wages and Social Security and Medicare wages, unlike 401(k) contributions, which reduce only taxable wages.
Imputed Income
If your employer provides group-term life insurance coverage above $50,000, the cost of coverage over that threshold is added to your taxable income. On the stub it usually appears as “GTL,” “imputed income,” or “group life.”9Internal Revenue Service. Group-Term Life Insurance No cash hits your account, but your YTD gross and taxable wages both tick up. The amounts are typically small, and they explain why the W-2 wage figure can exceed the cash you actually received.
The Social Security Wage Cap
Social Security tax is withheld at 6.2% of wages, but only up to $184,500 in 2026.10Social Security Administration. Contribution and Benefit Base Once your YTD earnings pass that threshold, Social Security withholding stops for the rest of the year and your net paycheck grows noticeably, though your gross has not changed. Medicare tax at 1.45% has no cap, and an additional 0.9% Medicare tax applies once wages exceed $200,000.11Internal Revenue Service. Questions and Answers for the Additional Medicare Tax If you were reverse-engineering YTD gross from your take-home deposits, this jump can throw the estimate off.
When Your Math Doesn’t Match the Stub
Small differences of a few dollars are usually rounding. Larger gaps almost always trace back to one of these:
- A December paycheck that carried a January check date, moving that income into this year’s YTD rather than last year’s.
- Retroactive pay adjustments, where a raise applied to earlier periods produced a lump-sum back-pay entry on one stub.
- Imputed income added quietly to the gross total.
- A mid-year pay rate change, so different periods have different per-check gross amounts.
If none of those fit, add up the after-tax deposits from your employer in your bank history and compare the total to the YTD net pay on the stub. Federal law requires employers to keep accurate payroll records, and any discrepancy should go to payroll.12U.S. Department of Labor. Fact Sheet 21 – Recordkeeping Requirements Under the Fair Labor Standards Act (FLSA)
Multiple Employers or a Mid-Year Job Change
Your current stub reflects earnings from your current employer only. If you started a new job in March, the YTD field on your August stub captures roughly five months, not eight. Your true YTD is that figure plus the final stub (or eventual W-2) from your previous employer.
The same holds if you hold two jobs at once. Neither employer sees the other’s payroll, so each stub shows only its own portion. Add them for the full picture. This also affects withholding: if each employer withholds as if its wages were your only income, the combined total may push you into a higher bracket than either employer is withholding for. A revised Form W-4 filed with one or both employers fixes it. Once an employer receives the new W-4, the updated withholding must take effect no later than the first payroll period ending 30 or more days after receipt.13Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
What to Do With the Number
Two situations bring most people to this calculation.
For a mortgage application, lenders project annual income by taking your YTD gross and extrapolating. If your pay is steady salary, they divide YTD gross by the months elapsed and multiply by 12: a $60,000 YTD figure through the end of August projects to $90,000 for the year. Variable income like commissions and bonuses gets more scrutiny; lenders generally average earnings over at least 12 months using your current stub plus prior-year W-2s, and if variable income is declining they must confirm the current level has stabilized before counting it.14Fannie Mae. Bonus, Commission, Overtime, and Tip Income
For withholding, YTD lets you check whether you’re on track before April. The IRS imposes an underpayment penalty unless your total payments cover at least 90% of this year’s tax or 100% of last year’s, whichever is smaller. If your adjusted gross income last year was over $150,000 ($75,000 if married filing separately), the prior-year safe harbor rises to 110%. The penalty is waived entirely if you owe less than $1,000 on your return.15Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty Divide your YTD gross and YTD withholding by the periods elapsed, multiply each by the total periods in your year, and compare projected withholding to projected tax. If withholding is short, submit a new W-4; the adjustment spreads across the remaining paychecks instead of hitting all at once in April.
