Year-to-Date (YTD) Totals on a Pay Stub, Explained

Next to each line on a pay stub you will usually see two figures: one for the current period and one labeled YTD, for year-to-date. The YTD column is a running total, and it is one of the most useful parts of the stub for checking accuracy.

What YTD means

YTD is the total of a line from the first pay date of the calendar year through the current pay date. If gross pay YTD says $12,000, it means $12,000 in gross wages has been paid so far this year. Every line can have its own YTD figure: gross pay, overtime, federal income tax, Social Security, Medicare, state tax, 401(k), health premiums and net pay.

How it is calculated

The rule is simple: this stub's YTD = the previous stub's YTD + this period's current amount.

For example, a biweekly employee earns $2,000 gross each period. After the first pay date of the year, gross YTD is $2,000. After the second, $4,000. After the sixth, $12,000. The same logic applies to each tax and deduction. If Social Security of $124 is withheld each period, Social Security YTD after six periods is $744.

YTD follows the pay date, not the work dates

Payroll taxes are based on when wages are paid. A pay period that runs from December 20 to January 2 but is paid on January 7 belongs entirely to the new year. That paycheck starts the new year's YTD totals, even though most of the work happened in December. This is why the pay date on every stub has to be right.

Why YTD totals matter

Annual limits

Several amounts have yearly limits, and YTD is how payroll tracks them:

• Social Security wage base. Social Security tax applies only up to an annual amount of wages, which is $184,500 for 2026 according to the Social Security Administration. Once YTD Social Security wages reach it, withholding stops for the year.
• Additional Medicare tax. Employers start withholding the extra 0.9% once YTD wages from that employer pass $200,000.
• Retirement contribution limits. The IRS sets the 401(k) employee deferral limit at $24,500 for 2026, with higher catch-up amounts for people 50 and older, per IRS guidance. YTD contributions show how close you are.

Year-end reporting

At year end, employers report annual wages and withholding on Form W-2. The final pay stub's YTD figures should line up with the W-2 boxes, allowing for the fact that some boxes use adjusted wages. For example, Box 1 wages usually exclude pre-tax 401(k) contributions, while Box 3 and Box 5 (Social Security and Medicare wages) usually include them.

Spotting errors early

If a stub's YTD does not equal the previous YTD plus the current amounts, something went wrong: a missed paycheck, a double entry, or a correction that was not carried through. Catching it mid-year is far easier than untangling it in January.

A quick YTD check you can do

1. Put two consecutive stubs side by side.
2. For each line, subtract the earlier YTD from the later YTD.
3. The result should equal the later stub's current amount.
4. Repeat for gross pay, each tax and net pay.

For example, if the April 11 stub shows federal income tax YTD of $1,050 and the April 25 stub shows $1,200 with a current amount of $150, it checks out: $1,200 minus $1,050 is $150.

When YTD starts mid-year

YTD does not always start at zero on a stub. A new employee hired in June starts at zero with the new employer, because YTD is tracked per employer. But a business that switches payroll systems mid-year must carry the existing YTD totals into the new system, or the new stubs will understate the year and annual limits will be tracked wrong.

Note that the Social Security wage base applies per employer for withholding. Someone with two jobs may have Social Security withheld by both even after combined wages pass the limit; any excess is generally handled on the individual's tax return. The FICA guide explains more.

YTD in a pay stub series

When you create pay stubs in PayStubNest as a series, the calculator carries YTD totals forward from one stub to the next automatically, and you can enter starting YTD amounts if payroll began partway through the year. Make sure each stub in the series reflects a paycheck that was actually issued, in the right order, with the right pay dates.
