Your year-to-date wages are your total earnings from January 1 through the date on the document you’re looking at, and the right figure to enter depends on whether the form is asking for gross wages or taxable wages. Those are two different numbers, and they live in different places on your pay stub and your W-2. Pick the wrong one and you can delay a refund, trigger an IRS notice, or throw off a mortgage application.
Gross Wages or Taxable Wages
Start by figuring out which one the form wants. Most requests fall into one of two camps.
Gross wages are your total compensation before anything is subtracted. Every dollar your employer paid you counts, including bonuses, overtime, and taxable fringe benefits. It’s the big number at the top of your pay stub.
Taxable wages are gross wages minus certain pre-tax deductions. If you pay for health insurance through a Section 125 cafeteria plan, those premiums come out of your paycheck before taxes are calculated, so they reduce your taxable total. Traditional 401(k) contributions do the same thing for federal income tax purposes, but they stay included in your Social Security and Medicare wage totals.
That split is what trips people up. A 401(k) deferral shrinks the federal taxable wage figure while leaving the Social Security and Medicare figures untouched. So if you contribute to a 401(k), you’ll have three different YTD wage numbers on the same document, and each one is correct for a different purpose.
Finding the YTD Number on a Pay Stub
When you need a current figure and it’s not year-end yet, your most recent pay stub is the source. Lenders, government benefits offices, and income verification forms all accept a recent stub.
Pay stubs display two columns for each earnings line: current period and YTD. The current column shows what you earned in that one paycheck. The YTD column is the running total from January 1 through that pay date. The YTD column is what you want.
Match the line to the request. If the form asks for gross income, use the “Gross Pay YTD” line. If it asks for federal taxable earnings, look for “Federal Taxable YTD” or a similarly labeled line, which already reflects the pre-tax adjustments taken so far this year.
For mortgage underwriting, Freddie Mac requires the pay stub to be dated no more than 30 days before the application, and most lenders follow similar standards. Pull a fresh stub from your payroll portal before you apply.
Finding the YTD Number on a W-2
Once the year is over, the W-2 is the definitive record. Employers must get it to you by January 31, and the same figures go to the Social Security Administration, so what you enter on your return needs to match.
Three boxes carry the wage numbers most forms and software ask about:
- Box 1, Wages, tips, other compensation, is your federal taxable wages: gross pay minus pre-tax items like cafeteria plan premiums and traditional 401(k) deferrals. Tax software uses this to calculate your federal income tax.
- Box 3, Social Security wages, is income subject to the 6.2% Social Security tax. It includes 401(k) deferrals that were excluded from Box 1, so it’s often higher. The total of Box 3 and Box 7 cannot exceed $184,500 for 2026.
- Box 5, Medicare wages and tips, has no annual cap, so it’s usually the highest wage figure on the form. All covered wages are subject to the 1.45% Medicare tax, plus an additional 0.9% on earnings above $200,000.
Two more boxes matter at the state and local level. Box 16 shows state wages and Box 18 shows local wages. These can differ from Box 1 because states and municipalities sometimes define taxable income differently than the federal government does.
Box 12 uses letter codes to report specific items. Code D is your total 401(k) elective deferrals; Code E covers 403(b) salary reduction contributions. Those amounts are already excluded from Box 1, so you don’t subtract them again. They’re reported separately so the IRS can verify contribution limits.
Which Number the Common Forms Want
Tax preparation software is the simplest case. Enter each W-2 box exactly as printed. Box 1 feeds your income calculation, Box 2 is federal tax already withheld, and Boxes 3 through 6 handle Social Security and Medicare. Don’t try to “fix” numbers that look off; enter what the W-2 says and deal with any discrepancies separately.
Mortgage and loan applications want current YTD gross income from a pay stub. Underwriters project your annual earnings from it and calculate your debt-to-income ratio. If your YTD gross through June is $45,000, the lender divides by the months worked and multiplies by 12 to estimate $90,000 annually. Overtime, bonuses, and commissions get more scrutiny; underwriters often average those over two years rather than projecting from a single stub.
Means-tested benefits programs, including Medicaid, SNAP, and health insurance marketplace subsidies, typically want gross income from your most recent pay stub. Because the projection is forward-looking, a mid-year raise or job change can shift eligibility. Update your application when your income changes.
If You Worked More Than One Job
Each employer issues a separate W-2, and you enter each one individually. Don’t combine them into a single total; tax software adds them together for you.
The wrinkle is Social Security tax. Each employer withholds 6.2% independently, with no visibility into what the other employer already took out. If your combined Social Security wages exceed the $184,500 wage base for 2026, you’ve overpaid. You claim the excess as a credit on Schedule 3, Line 11 of Form 1040. Medicare tax has no cap, so there’s no overpayment issue there no matter how many jobs you hold.
If Your W-2 Is Missing or Wrong
If January 31 passes and no W-2 has arrived, contact your employer. Payroll may have a stale address on file, and many employers post W-2s to a payroll portal rather than mailing them.
If you still can’t get one, file using Form 4852 as a substitute. You estimate your wages and withholding from your final pay stub of the year, and you explain on the form what you did to try to obtain the actual W-2. Skip this route if your pay stub only shows take-home pay with no breakdown of gross earnings and deductions; a prior-year W-2 from the same employer, adjusted for months worked, gives you more reliable numbers.
If the W-2 arrived but the numbers are wrong, ask your employer to issue a corrected Form W-2c. Employers use it to fix errors on W-2s already filed with the Social Security Administration. Don’t file a return with figures you know are wrong. An incorrect return can generate IRS matching notices months later, and those are harder to resolve than a corrected W-2 upfront.
The Cost of Entering the Wrong Figure
If a wrong wage entry causes you to understate your tax liability by more than the greater of 10% of the tax you actually owe or $5,000, the IRS treats it as a substantial understatement and adds a penalty equal to 20% of the underpaid amount. The penalty applies whether the mistake was intentional or not.
The most common trigger is entering Box 3 instead of Box 1, or the other way around. Forgetting a second W-2 from a part-time job does it too. The IRS gets copies of every W-2 your employers file, so the mismatch surfaces during automated matching.
If you catch the error after filing, amend the return with Form 1040-X as soon as you can. Fixing it before the IRS contacts you significantly reduces the chance of a penalty assessment.
