What Should I Claim on My W-2 If Married? Status and Withholding

If you got married and want to update your paycheck tax withholding, the form to change is the W-4, not the W-2. The W-2 is the year-end statement your employer sends you; you don’t claim anything on it. What to claim on a W-2 if married is really a question about the W-4, the withholding certificate you give your employer so payroll knows how much federal income tax to take out of each check.¹ After the wedding, both spouses should sit down with a fresh W-4 and work through it together, because filing status, combined income, and any dependents all change the math.

Before you start, pull recent pay stubs for both spouses, last year’s tax return, and a rough figure for any non-wage income (interest, dividends, freelance work, retirement distributions). You can download the current form from the IRS or get it through your employer’s payroll portal.

Step 1: Pick Your Filing Status

Step 1(c) asks you to check a box for the filing status you expect to use on your return. That single choice tells payroll which standard deduction and which tax brackets to apply.²

Married Filing Jointly

Most married couples check this box. Filing jointly usually produces the lowest combined tax because it gives you the widest brackets and the largest standard deduction: $32,200 for 2026.³ The 10% bracket runs through the first $24,800 of taxable income for joint filers in 2026, and the top 37% rate only kicks in above $768,700. Both spouses share responsibility for a joint return, so the status you check on the W-4 should match what you actually plan to file.

Married Filing Separately

This status uses narrower brackets and a smaller standard deduction of $16,100 for 2026, so combined taxes are generally higher.³ It can still make sense in specific situations: one spouse has large medical expenses, one spouse is on an income-driven student loan repayment plan, or you want to keep tax liabilities separate. Filing separately also disqualifies you from several credits and deductions, so weigh the trade-offs before checking it.

Head of Household

A married person can only check “Head of household” if they lived apart from their spouse for the last six months of the year and paid more than half the cost of keeping up a home for a qualifying dependent.² It doesn’t apply to a typical newly married couple living together.

Step 2: Handle Two Incomes

This is the step that trips up most married couples. When both spouses work, each employer withholds as if that job were the household’s only income. Combined, your earnings can land in a higher bracket than either paycheck reflects, and you end up owing at tax time. The W-4 gives you three ways to fix that.

Option (a) — IRS Tax Withholding Estimator. The online tool at irs.gov/W4App is the most accurate of the three. It pulls in both spouses’ wages, other income, deductions, and credits, then produces a pre-filled W-4. The IRS recommends this option when one spouse is self-employed, when any job pays more than $120,000, when there are more than three jobs in the household, or when you receive dividends, capital gains, or bonuses.⁴²
Option (b) — Multiple Jobs Worksheet. A paper worksheet on page 3 of the W-4. You use a table to look up the extra withholding based on the higher- and lower-paying jobs, then put that amount on line 4(c) of the W-4 for the highest-paying job only.²
Option (c) — The checkbox. If there are exactly two jobs in the household, both spouses can check the box in Step 2(c) on their own W-4s. This splits the standard deduction and brackets between the two jobs. It works well when both salaries are similar, but it can over-withhold when pay is very uneven.²

Skipping Step 2 is the most common reason married couples end up under-withheld. Even if one spouse earns much less, the combined income can still push the household into a higher bracket than either employer accounts for on its own.

Step 3: Dependents and Credits

Step 3 reduces your withholding to reflect credits you expect to claim. If your combined income is $400,000 or less on a joint return, you can claim the full Child Tax Credit of up to $2,200 for each qualifying child under age 17. Other qualifying dependents who don’t meet the child credit rules are worth a $500 credit each.⁵

Add up your expected credits and enter the total on the Step 3 line. That figure comes straight off your annual withholding. Above $400,000 of joint income, the credit phases out by $50 for each $1,000 of income over the threshold, so higher earners should scale back the Step 3 amount. The instructions on the current W-4 list the exact per-child and per-dependent figures; use those rather than a prior year’s numbers.

Step 4: Other Income, Deductions, and Extra Withholding

Step 4 is optional, but it’s where you fine-tune. Line 4(a) is for annual income you expect from sources with no withholding of their own — interest, dividends, capital gains, rental income, retirement distributions. Reporting it here lets your employer withhold enough to cover the tax on it.

Line 4(b) is for deductions. If your combined itemized deductions will exceed the $32,200 standard deduction for joint filers in 2026, enter the excess to reduce withholding.³ Most joint filers take the standard deduction, so this line often stays blank.

Line 4(c) is for a flat extra dollar amount you want withheld from every paycheck. If you used the Multiple Jobs Worksheet in Step 2, that result goes here. You can also use it to cover taxes on freelance income or to build in a refund cushion.

Submitting the New W-4

Sign and date the form, then send it to your employer’s HR or payroll department. An unsigned form isn’t valid. If your marriage reduces your withholding allowance, the IRS expects a new W-4 within 10 days.⁶ If switching to married filing jointly increases your allowance instead, a new W-4 is optional but still worth filing so you’re not over-withheld.

Your employer has to put the new withholding in place no later than the start of the first payroll period ending on or after 30 days from when they got the form.⁷ In practice, most process it for the next pay cycle. Check your next couple of paychecks to confirm the federal withholding figure changed, and keep a copy of the form you submitted.

Making Sure You Don’t Owe a Penalty

If your combined withholding falls too far short of what you owe, the IRS charges an underpayment penalty. You avoid it by meeting any one of these tests:⁸

Your balance due after withholding and estimated payments is under $1,000.
Your total payments cover at least 90% of the tax on your current-year return.
Your total payments equal at least 100% of the tax on your prior-year return, if that return covered a full 12 months. For couples whose prior-year adjusted gross income was above $150,000, the threshold rises to 110%.⁹

For a newly married couple, the practical target is straightforward: at minimum, make sure your combined withholding covers last year’s tax (or 110% of it above $150,000). Run the IRS Tax Withholding Estimator once mid-year to check whether you’re on track and adjust before any shortfall builds.⁴
