Year-to-Date (YTD) — Payroll Definition
Running total of earnings and deductions from January 1st through the current pay period.
Running total of earnings and deductions from January 1st through the current pay period.
Year-to-Date (YTD) figures on your paystub show the cumulative total of each line item since January 1st. YTD Gross shows your total earnings for the year so far; YTD Federal Tax shows total federal tax withheld, and so on. Your final paystub of the year should closely match your W-2 form. If there's a significant discrepancy (more than $50), contact your payroll department before tax filing season.
Example: Biweekly $2,000 gross, 10th check of the year → YTD Gross $20,000.00
Common pay stub code: YTD
What the YTD Columns Cover
Most stubs print two columns for every line: "current" for this pay period and "YTD" for the calendar year so far. That means there is a YTD figure for each earnings type (regular, overtime, bonus), for each tax (federal, state, local, Social Security, Medicare), for each deduction (401(k), medical, HSA, garnishment), and for net pay. YTD is driven by the pay date, not by when the work was performed, so hours worked in late December but paid in January land in the new year. Every YTD total resets to zero on the first paycheck issued in January.
Why YTD Totals Get Checked First
YTD is the fastest arithmetic check on a pay stub because it has to be internally consistent. YTD gross should equal current gross multiplied by the number of pay periods already paid, adjusted for variable items such as overtime or a bonus. YTD Social Security should be 6.2% of YTD Social Security wages until those wages reach the $184,500 wage base for 2026, and YTD Medicare should be 1.45% of YTD Medicare wages with no cap. YTD gross minus all YTD taxes and deductions should equal YTD net. Anyone reviewing a stub — you, your payroll department, or a tax preparer — can spot a mistyped rate or a missing pay period in seconds from those relationships.
Checking YTD Against Your W-2
Your last stub of the year is the bridge to your W-2, but the numbers rarely match line for line. Box 1 (federal taxable wages) equals YTD gross minus pre-tax deductions such as traditional 401(k), medical premiums, HSA, and FSA. Box 3 (Social Security wages) equals YTD gross minus Section 125 pre-tax benefits, capped at $184,500 for 2026 — a 401(k) deferral does not reduce it. Box 5 (Medicare wages) is the same as Box 3 without the cap. Box 2 should match YTD federal income tax withheld exactly, Box 4 your YTD Social Security tax, Box 6 your YTD Medicare tax, and Box 17 your YTD state tax. Differences in Boxes 2, 4, 6, and 17 are worth raising with payroll before you file.
Frequently Asked Questions
- What does YTD mean on a pay stub?
- YTD stands for year-to-date: the running total of that line item from January 1st through the current pay date. YTD gross is everything you have earned so far this year, YTD federal tax is everything withheld so far, and so on for each earning and deduction.
- Does YTD reset every year?
- Yes. Every YTD total goes back to zero on the first paycheck with a pay date in January. Because YTD follows the pay date rather than the work date, hours worked in December but paid in January count toward the new year.
- How do I calculate YTD gross pay?
- Add the gross pay from every paycheck issued so far this calendar year, including overtime, bonuses, and commissions. With steady pay you can shortcut it: gross per period × number of periods already paid. Ten biweekly checks of $2,000 give $20,000.00 YTD gross.
- Why does my YTD gross not match Box 1 of my W-2?
- Because Box 1 reports taxable wages, not gross wages. Pre-tax deductions — traditional 401(k), medical and dental premiums, HSA, FSA — are subtracted from YTD gross before it reaches Box 1. Box 3 and Box 5 are calculated differently again, since 401(k) deferrals still count as Social Security and Medicare wages.
