You can’t claim allowances on a W-4 anymore. The IRS eliminated allowances starting with the 2020 redesign, so if you’re looking at a current W-4 and hunting for the line where you write “1” or “2” or “0,” it isn’t there. In its place, the form asks for actual dollar amounts: the tax credits you expect for dependents, income from sources your employer doesn’t see, deductions above the standard amount, and any extra withholding you want taken from each paycheck. The result is the same goal the allowance system was built for — matching your withholding to your tax bill — reached through more direct math.
Why Allowances Are Gone
Each allowance used to reduce 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 floor out from under the allowance concept.1Internal Revenue Service. FAQs on the 2020 Form W-4 The redesigned W-4 skips the abstract middle step and asks for the underlying numbers directly.
If you filed a W-4 before 2020 and haven’t touched it since, your employer is still using those old allowances to calculate withholding. You don’t have to submit a new form, but if your life or income has shifted, the old numbers may no longer produce accurate withholding.
What the New Form Asks Instead
The current W-4 has five steps. Steps 1 and 5 — personal information and your signature — are required. Steps 2, 3, and 4 are where the old allowance decisions have been rebuilt as specific questions about your situation. A single filer with one job and no dependents can fill in Step 1, sign Step 5, and be done; the employer will withhold using the standard deduction and single-filer brackets. Anyone with a working spouse, a second job, dependents, or significant non-wage income needs the middle steps to get close to the right number.
Step 1: Filing Status
Your filing status sets the standard deduction and bracket structure your employer’s payroll system applies to your wages. For 2026:2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill
- Single or Married Filing Separately: $16,100
- Married Filing Jointly: $32,200
- Head of Household: $24,150
The common mistake here is selecting Married Filing Jointly when your spouse also works, without doing anything else. The withholding tables assume the full joint standard deduction and brackets apply to your wages alone, which under-counts your tax when a second income is in the picture. That’s what Step 2 is for.
Step 2: A Second Job or a Working Spouse
Combined income from more than one source can push your earnings into higher brackets that no single employer sees. Skip this step in a two-earner household and you’ll almost certainly owe at tax time. The form gives you three ways to handle it, and you pick one:3Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate
- Option (a), the IRS Tax Withholding Estimator at irs.gov/W4app, is the most accurate. It walks through your full picture and tells you what to write on each W-4.
- Option (b) is the Multiple Jobs Worksheet included with the W-4 instructions. You look up your wages in a table and put the result on line 4(c) as extra withholding per paycheck.
- Option (c) is a checkbox for households with exactly two jobs at roughly similar pay. Both W-4s check the box. It works best when the lower-paying job pays more than half of the higher-paying one.
If you’d rather not signal to one employer that you hold a second job, use the estimator. It will calculate extra withholding to enter on just one W-4, so neither employer sees the other job’s details.1Internal Revenue Service. FAQs on the 2020 Form W-4
Step 3: Dependents and Credits
This is where the old dependent allowances now live, expressed as the actual dollar value of your expected credits rather than a count. Two amounts apply on the 2026 form:3Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate
- $2,200 for each qualifying child under 17 (the Child Tax Credit)
- $500 for each other dependent (the Credit for Other Dependents)
Multiply, add the two totals, and put the sum on the Step 3 line. Payroll spreads the credit across your paychecks, so you feel the benefit through the year instead of waiting on a refund.
Qualifying Child vs. Other Dependent
A qualifying child for the $2,200 credit must be under 17 at year-end, live with you for more than half the year, and be a U.S. citizen or resident. Full-time students under 24 and permanently disabled children can be dependents, but because they don’t meet the under-17 rule, they fall into the $500 category. A qualifying relative — an elderly parent you support, for example — also counts for the $500 credit if their gross income is under $5,050 and they meet the residency and support tests.4Internal Revenue Service. Dependents
Income Phase-Outs
Both credits start phasing out at $200,000 of adjusted gross income for single filers and $400,000 for married filing jointly, dropping by $50 for every $1,000 of income above those thresholds.5Internal Revenue Service. Child Tax Credit If your income is near or above the threshold and you enter the full credit on Step 3, you’ll be under-withheld because the credit you actually claim on your return will be smaller. Use the estimator or reduce the Step 3 amount to match the credit you’ll really get.
Step 4: Other Income, Deductions, and Extra Withholding
Step 4 is optional and does the fine-tuning work the old allowance system tried to do indirectly. It has three lines.
Line 4(a): Other Income
Enter the expected annual total of income your employer doesn’t withhold on — interest, dividends, capital gains, rental income, retirement distributions. Your employer will withhold extra from your wages to cover the tax on it, which saves you from making quarterly estimated payments.
Line 4(b): Deductions Above the Standard
If you’ll itemize and your itemized deductions will top the standard deduction for your status, enter the excess here. 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.
Line 4(c): Extra Withholding
The simplest lever on the form. Enter a flat dollar amount and your employer adds it to every paycheck. People use this line to cover a side gig they’d rather not put on 4(a), to build in a refund buffer, or to plug the gap the Multiple Jobs Worksheet identified. Twenty-five or fifty dollars per biweekly check is often enough to close a small shortfall.
Claiming Exempt from Withholding
If you had zero federal income tax liability last year and expect zero this year, you can claim exempt. Check the box above Step 5, complete Steps 1(a), 1(b), and 5, and skip everything else. Your employer will withhold no federal income tax.3Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate
Exempt status expires. You have to submit a new W-4 claiming exempt by February 15 each year, or your employer must start withholding as if you filed as single with no adjustments.6Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate The option is mainly useful for people with very low income — a part-time student, for instance. Claim it when you don’t qualify and you’ll face the balance due plus a potential underpayment penalty.
Turning It In and Updating It Later
Sign Step 5 and submit the form to your employer’s payroll or HR department, or through their online portal. The employer completes its own section and keeps the form on file; it doesn’t go to the IRS unless the agency asks for it.3Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate Check your next pay stub or two to confirm the withholding looks right. If it’s off, rerun the estimator with your actual year-to-date numbers and submit a corrected form.
You can update a W-4 as often as you want. Revisit it after a marriage or divorce, a new child, a second job, or the loss of a spouse’s income. Any of those changes shifts your tax picture enough that a form left in place from last year can leave you well over or well under where you should be.
