How to Claim Allowances on a W-4: What Replaced Them

If you’re trying to figure out how to claim allowances on a W-4, the honest answer is that you can’t anymore. The IRS removed allowances from the form starting with the 2020 redesign, and the current W-4 doesn’t ask how many you want. Instead, it asks for dollar amounts: the tax credits you expect for dependents, deductions above the standard amount, and any other income your employer wouldn’t otherwise know about. Payroll uses those figures to calculate your withholding directly, without the allowance step in the middle.

Why Allowances Went Away

Each allowance under the old system reduced your taxable wages by a fixed amount tied to the personal exemption. The Tax Cuts and Jobs Act of 2017 set the personal exemption to zero, and that change has since been made permanent, which pulled the mathematical foundation out from under the allowance concept.¹ The redesigned W-4 replaced the abstract allowance count with plain questions about your situation, and the numbers you enter flow straight into the withholding calculation.

The form has five steps. Steps 1 and 5 (personal information and signature) apply to everyone. Steps 2, 3, and 4 are where the work of the old allowance worksheet now lives, and you fill them in only if they apply to you. A single filer with one job and no dependents can go straight from Step 1 to Step 5, and the employer will withhold based on the standard deduction for that filing status.

What Replaces Allowances on the New Form

Think of the new W-4 this way: everything the old allowance count was trying to approximate is now asked about directly. A dependent isn’t an allowance anymore; it’s a credit amount in Step 3. A working spouse isn’t a “minus two allowances” adjustment; it’s a specific calculation in Step 2. Extra withholding to cover a side income isn’t a negative allowance; it’s a flat dollar figure on line 4(c). The steps below walk through each replacement in the order they appear on the form.

Step 1: Filing Status

Your filing status sets which standard deduction and bracket schedule payroll applies to your wages. For 2026 the standard deduction amounts are:²

Single or Married Filing Separately: $16,100
Married Filing Jointly: $32,200
Head of Household: $24,150

Picking Married Filing Jointly when your spouse also works, without doing Step 2, is one of the fastest ways to under-withhold. The withholding tables assume the full joint standard deduction and bracket schedule are covering your wages alone, and they can’t see the other income.

Step 2: Two Jobs or a Working Spouse

Combined income from more than one source moves earnings into higher brackets that no single employer sees. Under the old form you would have cut your allowance count to compensate; the new form gives you three options, and you pick one:³

Option (a): the IRS Tax Withholding Estimator at irs.gov/W4app. This is the most accurate method and tells you exactly what to enter.
Option (b): the Multiple Jobs Worksheet packaged with the W-4 instructions. You look up your wages in a table, and the result goes on line 4(c) as extra per-paycheck withholding.
Option (c): the checkbox. If there are only two jobs total and the pay is roughly comparable, both W-4s check this box. It works best when the lower-paying job earns more than half of what the higher-paying job earns.

If you’d rather not signal a second job to one employer, use option (a). The estimator calculates a single extra-withholding figure for line 4(c) on one W-4, and the other employer sees nothing about the arrangement.¹

Step 3: Dependents and Credits

This is the closest thing on the new form to the old “dependent allowances.” Instead of counting people, you enter the dollar value of the credits those people generate. The 2026 W-4 uses two figures:³

$2,200 for each qualifying child under 17 (the Child Tax Credit)
$500 for each other dependent (the Credit for Other Dependents)

Multiply, add, and put the total on the Step 3 line. Payroll spreads the credit across your paychecks so you see it in take-home pay rather than at refund time.

Who Fits Each Category

A qualifying child for the $2,200 credit must be under 17 at year-end, live with you more than half the year, and be a U.S. citizen or resident. Full-time students under 24 and permanently disabled children of any age can be dependents, but they don’t meet the under-17 rule, so they land in the $500 “other dependent” category. A qualifying relative such as an elderly parent you support can also count for the $500 credit if their gross income is under $5,050 and they meet residency and support requirements.⁴

Higher Incomes: Watch the Phase-Out

Both credits phase out starting at $200,000 of adjusted gross income for single filers and $400,000 for married filing jointly, shrinking by $50 for every $1,000 above those thresholds.⁵ Entering the full credit amount when your income sits near or above the threshold will under-withhold you, because the actual credit on your return will be smaller than the W-4 assumed. The IRS estimator handles the reduction automatically; otherwise scale the Step 3 amount down by hand.

Step 4: Other Income, Deductions, and Extra Withholding

Step 4 is optional, and it’s where you fine-tune. It has three lines.

Line 4(a): Other Income

Enter the annual total of income no employer withholds on: interest, dividends, capital gains, rental income, retirement distributions. Your employer will withhold extra from your wages to cover the tax on it, which spares you from having to make quarterly estimated payments.

Line 4(b): Deductions Above the Standard Amount

If you’ll itemize and your itemized deductions exceed the standard deduction, enter the excess here — only the amount above the standard deduction, not the full itemized total. A single filer with $26,000 in itemized deductions would enter $9,900 ($26,000 minus $16,100). Common itemized deductions include state and local taxes (capped at $40,400 for most filers in 2026, up from the $10,000 cap that applied from 2018 through 2025), mortgage interest, and charitable contributions. The W-4 instructions include a Deductions Worksheet that walks the calculation.

Line 4(c): Extra Withholding

Enter any flat dollar amount and your employer adds it to every paycheck. This is the simplest lever on the form. People use it to cover side income they don’t want to itemize on 4(a), to build in a refund cushion, or to close the gap the Multiple Jobs Worksheet identified. An extra $25 or $50 per biweekly paycheck is often enough to keep April uneventful.

Claiming Exempt from Withholding

Exempt status is one piece of the old system that still works about the same way. If you had zero federal income tax liability last year and expect the same this year, you can claim exemption on the 2026 W-4 using the checkbox above Step 5.³ When you claim exempt, you complete only Steps 1(a), 1(b), and 5 and skip everything else, and your employer withholds no federal income tax.

Exempt status expires every year. You must submit a new W-4 claiming exempt by February 15 of the following year, or your employer must switch to withholding as if you were single with no adjustments.⁶ Set a January reminder if you’re going to use it. And if you claim exempt and end up owing tax, you’ll face both the balance and a potential underpayment penalty, so the option really only fits people with genuinely low income, such as part-time students.

Turning It In and Checking Your Work

Sign Step 5 and submit the form to HR or through your employer’s payroll portal. The employer completes their own section and keeps the form on file; it isn’t sent to the IRS unless specifically requested.³ New withholding usually takes effect on the first payroll run after processing. Look at your next pay stub or two and compare the federal withholding against what you expected. If the number is off, rerun the IRS Tax Withholding Estimator using your year-to-date figures and submit a corrected W-4.

You can update the form as often as you want. At a minimum, revisit it after a marriage, divorce, birth, adoption, a new second job, or the loss of a spouse’s income. Each of those shifts the numbers enough that last year’s W-4 could leave you badly over- or under-withheld. If under-withholding is what you’re worried about, aim your total year’s withholding at either 90% of this year’s tax or 100% of last year’s total tax (110% if your prior-year adjusted gross income was over $150,000, or $75,000 if married filing separately), which are the safe harbors that keep the underpayment penalty from applying.⁷
