Federal Withholding Calculator 2026 (Pub 15-T)
Your employer withholds federal income tax from every paycheck based on Form W-4. This calculator estimates that amount with the official 2026 Percentage Method Tables for Automated Payroll Systems from IRS Publication 15-T — the same tables payroll software uses.
Default hero example
| Input | Value |
|---|---|
| Filing status | Single |
| Pay frequency | Biweekly (26) |
| Gross wages / period | $2,000 |
| Pre-tax deductions | $0 |
| Step 2 checkbox | Off |
| Withheld this period | $195.85 |
| Withheld for the year | $5,092 |
taxable wages = gross wages − pre-tax deductions
adjusted annual wage = taxable wages × pay periods per year
tentative annual withholding = percentage-method table for your filing status
withholding per period = tentative annual withholding ÷ pay periods per year
What each input changes
| Input | Effect on withholding |
|---|---|
| Gross wages | Bigger paycheck → higher bracket → higher withholding |
| Pre-tax deductions (401(k), medical, HSA) | Lower taxable wages → less withheld now |
| Filing status (Step 1c) | Married Jointly and Head of Household have higher zero-tax bands → less withheld |
| Step 2 checkbox | Uses the lower-threshold table → more withheld, fewer April surprises |
Worked math ($2,000 biweekly, single)
- Adjusted annual wage: $2,000 × 26 = $52,000
- Standard Single table: $1,240 + 12% × ($52,000 − $19,900) = $5,092/yr
- Per period: $5,092 ÷ 26 = $195.85
If the same worker checks Step 2, the lookup moves to the Step 2 table: $2,900 + 22% × ($52,000 − $33,250) = $7,025/yr → $270.19/period (~$74 more on purpose).

| Single | $2,000 | Biweekly (26) | $52,000 | $195.85 | $5,092 |
| Married filing jointly | $5,000 | Monthly (12) | $60,000 | $365.67 | $4,388 |
| Single + $200 pretax | $2,000 | Biweekly (26) | $46,800 | $171.85 | $4,468 |

It uses the 2026 Percentage Method Tables from IRS Publication 15-T: annualize taxable wages (gross minus pre-tax deductions × pay periods), apply the table for your filing status, then divide by pay periods. Hero default: single $2,000 biweekly → $195.85 this period / $5,092 per year.
If you checked Step 2 (two jobs, or you and your spouse both work), your employer uses the lower-threshold table, which increases withholding so you don't owe a large balance at tax time. Same $2,000 biweekly single jumps from $195.85 to about $270.19 per period.
This version excludes the dependents credit (Step 3), other income (Step 4a), itemized deductions (Step 4b), extra withholding (Step 4c), nonresident alien rules, and state/local taxes. Educational estimate, not tax advice.
