On the current federal Form W-4, there is no number of allowances to enter. The IRS removed withholding allowances from the federal W-4 starting in 2020 and replaced them with a five-step process that asks for specific dollar amounts for dependents, other income, and deductions.1Internal Revenue Service. FAQs on the 2020 Form W-4 If you are looking at an older form or a state withholding form that still asks for a number, that field works the way it always did: each allowance shields a set amount of your wages from withholding, so a higher number means less tax taken out per paycheck and a lower number means more.
What Allowances Used to Mean
Under the pre-2020 federal system, each allowance you claimed represented a fixed dollar amount of income your employer treated as not subject to withholding. Payroll subtracted the total value of your allowances from your gross wages before running the withholding calculation. Claim more, and less tax came out of each check. Claim fewer, and more came out.
The dollar value of each allowance was tied to the personal exemption amount set by Congress. When the Tax Cuts and Jobs Act suspended personal exemptions starting in 2018, that link broke, and the IRS redesigned the W-4 for 2020.1Internal Revenue Service. FAQs on the 2020 Form W-4 The term “withholding allowance” still exists in federal regulations as a figure determined by IRS computational procedures based on filing status, dependents, and expected credits.2eCFR. 26 CFR 31.3402(f)(1)-1 – Withholding Allowance But you no longer pick a number on the form itself.
What the Federal W-4 Asks For Now
The current W-4 uses five steps, and only two of them are required. If you complete Steps 1 and 5 and skip the rest, your employer withholds based on your filing status and the standard deduction alone.
- Step 1 — Personal information. Name, Social Security number, and filing status (single, married filing jointly, or head of household). Your filing status sets the standard deduction used in the withholding calculation. For 2026, the standard deduction is $16,100 for single filers, $32,200 for joint filers, and $24,150 for heads of household.3Internal Revenue Service.

- Step 2 — Multiple jobs or a working spouse. If you hold more than one job or your spouse also works and you file jointly, this step accounts for the combined income. You can use the IRS online estimator, the form’s worksheet, or simply check a box when there are exactly two jobs total.4Internal Revenue Service. Employee’s Withholding Certificate – Form W-4
- Step 3 — Dependents and credits. Multiply qualifying children under 17 by $2,200, other dependents by $500, and enter the total. This dollar figure reduces the tax withheld each pay period.4Internal Revenue Service. Employee’s Withholding Certificate – Form W-4
- Step 4 — Other adjustments. Enter non-job income you want covered by withholding, claim deductions beyond the standard deduction to lower withholding, or request a flat extra dollar amount withheld each pay period.4Internal Revenue Service. Employee’s Withholding Certificate – Form W-4
- Step 5 — Signature. Sign and date under penalties of perjury.4Internal Revenue Service. Employee’s Withholding Certificate – Form W-4
Step 3 is the closest thing on the new form to the old “allowances for dependents” question. Instead of picking a number, you enter the actual dollar value of the credits you expect to claim.
Qualifying Children Versus Other Dependents
The dollar amounts in Step 3 depend on which category each dependent falls into. A qualifying child for the child tax credit must be under 17 at the end of the tax year, and the credit is worth up to $2,200 per child for 2026.5Internal Revenue Service. Child Tax Credit Other dependents, including children who are 17 or 18, full-time students under 24, and qualifying relatives, are worth $500 each.
To count as a qualifying child at all, a dependent must meet relationship, age, and residency tests. The child must be your son, daughter, stepchild, sibling, or a descendant of one of these; must be under 19 at year-end (or under 24 if a full-time student, or any age if permanently and totally disabled); and must live with you for more than half the year.6Internal Revenue Service. Dependents A child who meets those tests but is 17 or older still gets counted, just at the $500 rate rather than $2,200.
State W-4 Forms May Still Use Allowances
The 2020 federal redesign did not change state withholding forms. Many states still ask you to enter a number of allowances for state income tax purposes, which means you may fill out two different forms when you start a job: the federal W-4 with dollar-based entries and a state form with a traditional allowance count.
On a state allowance form, the old logic applies. Each allowance lowers the state wages subject to withholding by a set amount. More allowances means less state tax withheld, fewer means more. State allowance values and rules vary, so check your state tax agency’s instructions rather than assuming the federal rules carry over.
Claiming Exempt Instead of Adjusting Allowances
One reason people used to zero out or maximize allowances was to eliminate withholding entirely. The current W-4 handles this through a specific exempt claim rather than through an allowance number. You can claim exemption from federal income tax withholding only if you had no federal income tax liability in the prior year and expect none in the current year.4Internal Revenue Service. Employee’s Withholding Certificate – Form W-4 “No tax liability” means your total tax was zero (or fully offset by credits) or your income was below the filing threshold for your status.
Exempt status expires every year on February 15. If you do not submit a new W-4 claiming exemption by that date, your employer must start withholding as if you are single with no adjustments, which is the highest default level. When February 15 falls on a weekend or holiday, the deadline moves to the next business day.7Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
When to Update Your W-4
The IRS recommends checking your withholding at least once a year.8Internal Revenue Service. Taxpayers Should Check Their Federal Withholding to Decide if They Need to Give Their Employer a New W-4 Certain events change your tax picture enough to warrant an immediate review:
- Getting married or divorced, which changes your filing status and standard deduction.
- Having or adopting a child, which can add up to $2,200 in Step 3 credits.
- Starting or losing a second job, which can push you into a higher bracket.
- A spouse starting or stopping work in a two-income household.
- Buying a home, if mortgage interest lets you itemize deductions you can reflect in Step 4(b).
- Retiring and shifting from wages to retirement income.
The IRS lists all of these as reasons to run a withholding check.9Internal Revenue Service.
