Year-to-date earnings on a paycheck are the running total of what your employer has paid you since January 1 of the current year, through the date on that stub. The figure appears twice: gross YTD, which is everything you’ve earned before deductions, and net YTD, which is what actually reached your bank account. Both numbers reset to zero on the next January 1, and both are the quickest way to catch a payroll mistake, stay under annual contribution limits, and check that your withholding is on track.
Gross YTD and Net YTD
Gross YTD is your total taxable compensation for the year so far: base wages, overtime, bonuses, commissions, and any other pay your employer owes you before anything is subtracted. This is the figure that drives your income tax and payroll tax liability.
Net YTD is what’s left after federal and state income tax, Social Security, Medicare, insurance premiums, retirement contributions, and any other deductions come out. The gap between the two lines is the fastest read on your effective tax and benefits burden. If your gross YTD is $60,000 and your net YTD is $42,000, roughly 30 cents of every dollar you earned went somewhere other than your checking account.
One nuance matters if you switched jobs. The YTD on your current stub reflects only what you’ve earned at that employer since your start date. Your calendar-year earnings for tax purposes include wages from every employer you worked for, which is why filing a return with multiple W-2s means adding those YTD figures together, not treating any one of them as your total.
What Sits Between Gross and Net
The deductions that separate your gross YTD from your net YTD fall into two groups.
Mandatory withholdings come first. Federal income tax comes out based on the information you gave your employer on Form W-4, including filing status, other jobs, dependents, and any extra withholding you requested.1Internal Revenue Service. Form W-4 Most states with an income tax use a similar process on their own forms. These amounts are prepayments toward your annual tax bill; too much withheld means a refund, and too little means you owe the difference, potentially with a penalty.
FICA taxes fund Social Security and Medicare. Social Security is 6.2% of wages, Medicare is 1.45%, and together they take 7.65% out of every paycheck.2Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Your employer matches those amounts, but only your share shows on the stub. High earners see a third FICA line kick in later in the year: an extra 0.9% Additional Medicare Tax that employers must start withholding once your wages pass $200,000, regardless of filing status.3Internal Revenue Service. Topic No. 560, Additional Medicare Tax Your actual liability threshold on your return may differ ($250,000 for married filing jointly, $200,000 for single, $125,000 for married filing separately), and any gap gets settled at filing.4Internal Revenue Service. Questions and Answers for the Additional Medicare Tax
Then there are voluntary deductions, which are the benefits you elected: health, dental, and vision premiums, 401(k) contributions, HSA and FSA contributions, life insurance, commuter benefits, and similar items. Many of these come out pre-tax. A 401(k) deferral reduces the wages subject to federal income tax, and benefits elected through a Section 125 cafeteria plan, including health premiums and FSA contributions, are excluded from your gross income entirely.5Office of the Law Revision Counsel. 26 USC 125 – Cafeteria Plans That’s why the wages in Box 1 of your W-2 end up lower than the gross YTD on your final pay stub of the year.
2026 Thresholds Your YTD Tells You You’re Approaching
Several annual limits are enforced against YTD totals, and crossing one changes your paycheck immediately or creates a tax problem at filing. For 2026:
- Social Security wage base — $184,500. Once your gross YTD crosses this figure, your employer stops withholding the 6.2% Social Security tax for the rest of the year, and your net pay bumps up on the paycheck where the cap hits. Medicare has no wage cap and keeps applying to every dollar.6Social Security Administration. Contribution and Benefit Base
- 401(k) elective deferral limit — $24,500. That’s the ceiling on your own paycheck contributions to a 401(k), 403(b), or similar plan. Employees 50 and older can add up to $8,000 in catch-up, and those aged 60 through 63 can contribute an enhanced catch-up of up to $11,250 under SECURE 2.0.7Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- HSA contribution limit — $4,400 self-only or $8,750 family. Maximum you can contribute to a Health Savings Account in 2026.8Internal Revenue Service. Expanded Availability of Health Savings Accounts Under the One, Big, Beautiful Bill Act
- Additional Medicare Tax trigger — $200,000. Employer withholding of the 0.9% surtax begins here.3Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Most payroll systems automatically stop 401(k) and HSA deductions when you hit the limit at that employer. The YTD contribution lines on your stub are how you verify that the automatic stop is working, and, more importantly, how you track your position when you have plans at more than one employer.
Two Jobs, Two Independent YTDs
Each employer keeps its own YTD records, and neither knows what the other is doing. Two problems follow from that.
You can accidentally exceed the 401(k) deferral limit by contributing at both employers. The IRS puts the burden on you to monitor combined deferrals across all plans.9Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits Excess contributions that aren’t distributed by mid-April of the following year get taxed twice: once in the year contributed, and again when eventually withdrawn.
You can also overpay Social Security. Both employers will withhold 6.2% on wages up to $184,500 each. If your combined wages exceed that base, you paid more Social Security tax than you owed, and you claim the excess as a credit against income tax when you file your Form 1040.10Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld You and your spouse calculate the excess separately, even on a joint return.
Reconciling Your Final Pay Stub to Your W-2
Your last pay stub of the year and your W-2 should tell the same story, because both are built from wages paid during the calendar year.11Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026) Three boxes are worth checking against your YTD figures:
- Box 1, Wages, Tips, Other Compensation. This is your gross YTD minus pre-tax deductions like 401(k) contributions and cafeteria plan benefits. Expect it to be lower than your gross YTD.
- Box 3, Social Security Wages. Total wages subject to Social Security tax, capped at $184,500.
- Box 5, Medicare Wages and Tips. Total wages subject to Medicare tax. With no cap, this is often higher than Box 3 for high earners.
If a box doesn’t line up with what your stub suggests, don’t file with numbers you suspect are wrong. Ask your employer for a corrected W-2 (Form W-2c) before the April filing deadline. The IRS receives your W-2 independently, and mismatched numbers on your return are one of the fastest ways to draw a notice.
When Your YTD Numbers Look Wrong
Payroll errors happen. A missed overtime shift, a duplicate deduction, a bonus coded to the wrong pay type — any of these can throw off a YTD line, and the sooner you catch it, the easier the fix. Checking each stub against your own records is the most reliable way to notice early.
Pull your prior stubs, your offer letter or contract, timesheets, and any written communication about pay rates or bonus terms. Work out what the YTD figure should be, find the pay period where the numbers diverge, and bring that to payroll or HR with your documentation. Federal regulations require employers to keep payroll records for at least three years, so the underlying data is there to verify.12eCFR. 29 CFR Part 516 – Records to Be Kept by Employers Get a timeline for the correction in writing, and check that it appears on the next stub. If your employer won’t fix a real error, you can file a complaint with your state labor agency or the U.S. Department of Labor’s Wage and Hour Division.
