What does YTD mean on a pay stub?

YTD stands for year to date. On a pay stub, most lines have two amounts: what was paid or withheld this pay period, and the YTD total for that line from January 1 through this paycheck. Gross pay, each tax, each deduction and net pay all have their own YTD figure.

YTD = the YTD on your last stub + this paycheck. It starts over with the first paycheck of each calendar year.

How YTD adds up each pay period

Take an employee paid $2,000.00 every two weeks in 2026, filing single, working in Texas. Each paycheck has $156.15 of federal income tax, $124.00 of Social Security and $29.00 of Medicare, leaving $1,690.85 of net pay. Here's how the YTD column grows:

When pay is the same every period, YTD is simply this paycheck times the number of paychecks so far. Once there's a raise, overtime, a bonus or unpaid time off, it isn't: YTD is the actual total paid, which is why each stub builds on the one before it.

YTD follows the pay date, not the pay period. A paycheck for late-December work that's paid in January starts the new year's YTD, and it's reported on the new year's W-2.

Why YTD matters

YTD isn't just a running total. Payroll uses it to decide what to withhold, and other people use it to judge your income.

• Social Security stops at the wage base. The 6.2% tax applies only to the first $184,500 of wages in 2026. Payroll watches YTD wages and stops withholding once they reach that figure, so the most one employer withholds in 2026 is $11,439.00.
• Additional Medicare starts at $200,000. Employers must withhold an extra 0.9% of Medicare on wages over $200,000 in a calendar year, regardless of filing status. YTD is how they know when you cross that line.
• Some state programs have caps too. A few state disability and paid leave deductions stop once YTD wages reach a yearly limit, so their YTD stops growing.
• Loans and rentals. Lenders and landlords use YTD gross to check that your income is steady and matches what you've told them, and they compare it with your W-2s and tax records.
• Year-end checks. Your last stub of the year should line up with your W-2, so YTD is the easiest way to catch an error before tax time.

Worked example: when Social Security stops

A higher earner shows YTD at work. Say an employee is paid $10,000.00 every two weeks, or $260,000 a year.

On paycheck 19, YTD wages go from $180,000.00 to $190,000.00, but only $4,500.00 of that is under the $184,500 wage base, so Social Security is $4,500.00 × 6.2% = $279.00. From paycheck 20 on, there's no Social Security at all. Paycheck 20 brings YTD to exactly $200,000.00, so Additional Medicare starts with paycheck 21: 0.9% of $10,000.00 is $90.00. More on both taxes in FICA tax explained.

Each employer tracks its own YTD. If you have two jobs, or change jobs during the year, each employer withholds Social Security up to the wage base on its own, and you may be able to claim the excess as a credit on your tax return (IRS Topic 608).

Starting mid-year

A new job starts at zero. If you were hired in September, your YTD at that employer covers only the paychecks since then. Pay from your old job stays on your old employer's records and on the W-2 they send you. The same goes for a new business paying its first employee.

When you make pay stubs for someone who started this year, don't count pay periods back to January 1. Count only the periods they've actually been paid for, or enter what was really paid before the first stub. How year-to-date works shows both ways in the Paystub.biz builder.

What to do if YTD looks wrong

Start with one test: does this stub's YTD equal the last stub's YTD plus this period's amount? If it does, the totals are consistent, even if they look high or low. If it doesn't, look for these common causes:

• A new hire treated as if they'd worked since January. YTD should start with their first paycheck.
• This paycheck counted twice. Previous YTD should cover only earlier paychecks.
• The wrong pay frequency. Biweekly (26 paychecks) and semimonthly (24) give different counts by any given date.
• A January stub that didn't reset. The first paycheck dated in a new year starts YTD over.
• Social Security YTD below 6.2% of gross YTD. That's often correct: health insurance through a cafeteria plan isn't subject to Social Security, and the tax stops at the wage base.

On a stub from your employer, ask payroll to correct it; the fix usually shows up on the next paycheck. On a stub you're making yourself, my YTD totals look wrong explains how to fix each case. The paystub builder works out YTD from the pay date and frequency, and lets you enter previous YTD when the year so far hasn't been even.
