How Many Allowances Should I Claim When Married Filing Jointly?

If you’re wondering how many allowances to claim on your W-4 as a married couple filing jointly, the short answer is none: allowances were removed from Form W-4 starting in 2020, and the form no longer has a place to enter a number.¹ Instead of counting allowances, each spouse fills out a redesigned W-4 that asks for filing status, dollar amounts for dependent credits, and adjustments for a second income or other deductions. The aim is the same as before: match what your employer withholds to what you’ll actually owe, so you don’t get hit with a balance due at filing time.

Why Allowances Are Gone

Each allowance on the old W-4 reduced taxable wages by a dollar figure tied to the personal exemption. When Congress eliminated personal exemptions through tax reform, the allowance concept lost its basis, and the IRS rebuilt the form around direct dollar inputs.¹ Employers are still required by law to withhold federal income tax from wages, but the calculation now works from the answers you give on the current form rather than a claimed number.²

Old advice about claiming “2 allowances” or “0 allowances” as a married couple no longer maps onto anything on the form. What follows is what to do instead.

Filling Out the W-4 as a Married Couple

Each spouse gives a separate W-4 to their own employer.³ The form has five steps. Steps 1 and 5 are required; Steps 2, 3, and 4 are where the real choices happen.

Step 1: Check Married Filing Jointly

Check the “Married filing jointly” box. That single choice tells the payroll system to apply the joint standard deduction and the wider joint brackets. For 2026, the standard deduction for a joint return is $32,200, and the 10 percent bracket runs to $24,800 of taxable income before 12 percent takes over.⁴

Step 2: Handle the Second Income

This is the step married couples skip most often, and it’s the most common reason a joint return ends up with a balance due. When both of you work, each employer withholds as if its paycheck were the household’s only income. Combined on your return, the wages can land in a higher bracket than either job’s withholding assumed. Step 2 fixes that in one of three ways:

The IRS Tax Withholding Estimator at irs.gov/W4App is the most accurate option. It pulls in both incomes, credits, deductions, and paychecks remaining in the year, and returns a specific dollar figure to put on line 4(c).⁵
The Multiple Jobs Worksheet on page 3 of the W-4 instructions estimates the extra withholding from income ranges. The result also goes on line 4(c).³
Step 2(c) is a checkbox each of you can mark when the household has exactly two jobs at roughly similar pay. Checking it splits the standard deduction and brackets between the two jobs. It’s the simplest method but less precise when incomes are uneven.³

The estimator and the worksheet both feed a plain dollar figure into line 4(c), so nothing on your form tells your employer what your spouse earns. The 2(c) checkbox doesn’t disclose income either, though it does signal that a second job exists in the household.

Step 3: Enter Credits for Dependents

Step 3 replaces what used to be an allowance for each child. It reduces withholding by the credits you expect to claim. For 2026, if your joint income is $400,000 or less:

Enter $2,200 per qualifying child under 17 on line 3(a).³
Enter $500 per other dependent on line 3(b) — older teens, college students, or elderly relatives you support.³

Only one spouse should enter these amounts. If both W-4s claim the same children, the combined withholding will run short and you’ll owe at filing. Credits begin to phase out once joint income passes $400,000.³

Step 4: Fine-Tune With Dollar Amounts

Step 4 has three optional lines:

Line 4(a) is for non-wage income you expect that won’t have tax withheld, such as interest, dividends, or retirement distributions. Entering an annual amount here raises your paycheck withholding to cover it, which can replace quarterly estimated payments.³
Line 4(b) is for deductions above the $32,200 standard deduction. If you plan to itemize, or you have above-the-line deductions like student loan interest (up to $2,500), use the Deductions Worksheet in the W-4 instructions and put the result here.⁴
Line 4(c) is any flat extra dollar amount you want withheld each paycheck, and it’s where the Step 2 estimator or worksheet result belongs.

Step 5: Sign and Turn It In

Sign and date the form. The signature affirms under penalty of perjury that the information is correct.³ Submit it to payroll or HR; some employers take paper, others use a digital portal. An employer cannot reject a properly completed W-4 or push you toward particular options.

When to Submit a New W-4

A W-4 stays on file until you replace it, so there’s no annual filing requirement if nothing has changed. Certain events do call for an update:

Getting married. The IRS says newlyweds should file a new W-4 within 10 days of the change in filing status.⁶
Having or adopting a child, which adds up to $2,200 in credits on Step 3.
A spouse starting or leaving a job, which changes whether Step 2 applies.
Divorce or separation, which changes both filing status and dependents.
Large income shifts — a raise, a new bonus structure, or new investment income that pushes you into a higher bracket or triggers credit phaseouts.

After any of these, the IRS recommends running the Tax Withholding Estimator to recalculate.⁷

How to Know You’re Withholding Enough

If withholding falls short over the year, the IRS can add an underpayment penalty on top of the balance owed. You avoid the penalty entirely by meeting any one of these safe harbors:

You owe less than $1,000 after withholding and credits.⁸
Your withholding and estimated payments cover at least 90 percent of the current year’s tax.⁹
Your withholding covers at least 100 percent of last year’s total tax, or 110 percent if your adjusted gross income last year was over $150,000.⁹

The 110 percent rule catches many joint filers, since two incomes often push a household past the $150,000 line. If last year was a high-income year, aim withholding at 110 percent of that prior-year tax to stay safe. The IRS may also waive the penalty when the underpayment resulted from a casualty, disaster, or retirement after age 62.¹⁰

Claiming Exemption From Withholding

A married couple can claim complete exemption from federal income tax withholding only if you had zero federal income tax liability last year and expect zero liability this year.³ In practice, that describes very low-income households whose standard deduction and credits wipe out the entire bill. An exemption expires on February 15 of the following year, so it has to be renewed on a new W-4 each year to stay in effect.

Checking the Paycheck After You Submit

Updated withholding usually shows up within one or two pay cycles. Look at the federal income tax line on your pay stub and confirm the amount moved the direction you expected. Mid-year changes deserve a second look, because the remaining paychecks have to absorb an adjustment that ideally would have spread across all 12 months. The IRS estimator handles this when you enter your year-to-date withholding, producing a per-paycheck figure for the rest of the year.⁵ Running it again in late fall catches anything still off before the year closes.
