W-4 Tax Withholding Calculator
Will this year's paychecks withhold enough federal income tax? Enter your W-4 and pay to see the expected refund or balance due, and the Step 4(c) amount that would make it zero.
| Federal tax withheld per paycheck | $295.00 |
| Withheld over the full year | $7,670.00 |
| Estimated 2026 federal income tax | $7,670.00 |
| Difference | $0.00 |
Withholding follows IRS Publication 15-T for a 2020-or-later W-4 and assumes the same pay every period for the whole year. The tax estimate covers ordinary income and the Child Tax Credit only.
How Form W-4 controls your withholding
Since 2020 the W-4 has no "allowances". Instead, five steps feed the withholding formula in IRS Publication 15-T:
- Step 1 filing status picks the withholding table and the built-in standard deduction ($16,100 single, $32,200 joint, $24,150 head of household in 2026).
- Step 2(c) halves the bracket widths for households with two incomes.
- Step 3 subtracts a fixed annual credit amount from the tentative withholding.
- Step 4(a) adds other income to the annual wage; 4(b) subtracts deductions above the standard deduction; 4(c) adds a flat extra amount per paycheck.
annual withholding = table(annual wages + 4(a) − 4(b) − built-in amount) − Step 3 credits per paycheck = annual withholding ÷ pay periods + 4(c) refund (or due) = annual withholding − estimated income tax for the year
The built-in amount ($8,600, or $12,900 for married filing jointly, with the box in Step 2 unchecked) is how the tables incorporate the standard deduction; it is not a deduction you claim.
Frequently asked questions
How does this withholding calculator work?
It runs your pay and Form W-4 entries through the same IRS Publication 15-T percentage method your employer uses, multiplies by your pay periods to get a full year of withholding, then compares that with an estimate of your federal income tax for the year (standard deduction, brackets and the Child Tax Credit). The difference is your expected refund or balance due.
How do I increase my withholding?
Enter a dollar amount on Step 4(c) of a new Form W-4 and give it to your employer; that amount is withheld from every paycheck in addition to the table amount. The calculator suggests the Step 4(c) figure that would break even for the rest of a full year.
How do I reduce my withholding?
Claim your dependents on Step 3 (Child Tax Credit amounts), enter expected itemized deductions above the standard deduction on Step 4(b), or remove any extra amount on Step 4(c). Do not overstate deductions; underpayment penalties can apply if you withhold far too little.
Should I check the Step 2(c) box?
Check it if you have two jobs at once or you are married filing jointly and both spouses work with similar pay. It halves the withholding brackets so each job withholds as if it were half the household income. If the incomes are very different, the IRS Tax Withholding Estimator or the Multiple Jobs Worksheet gives a closer answer.
Why is my withholding higher than my tax?
Withholding tables assume the same pay every period and only know what is on your W-4. If you have credits or deductions not on the form, or you worked only part of the year, the table over-withholds and you get a refund. Enter them on the W-4 to bring withholding in line.
What does this calculator not cover?
Bonuses and supplemental wages (withheld at a flat 22% federal rate), self-employment income without withholding, capital gains, refundable credits and state tax. For a complete picture use the IRS Tax Withholding Estimator alongside this check.
