What does this withholding calculator estimate?
It estimates regular federal income tax for the year, compares that with withholding already taken and your current per-paycheck amount, then shows a simple target amount for the remaining paychecks.

How is the target calculated?
The target equals estimated annual regular federal income tax minus federal withholding already taken, divided by the number of paychecks remaining. A result of zero means the simplified model does not require additional regular federal withholding to cover the estimated tax.
Is this the same as the official IRS Tax Withholding Estimator?
No. The official IRS estimator collects more information, accounts for more tax provisions and can produce Form W-4 recommendations. This page is a faster planning estimate.
When should withholding be reviewed?
The IRS recommends checking withholding after major changes such as a new job, income changes, marriage, divorce, a new child or other events that affect tax liability.
Worked example: Tax Withholding
Enter the following values in the Tax Withholding Calculator and calculate to reproduce this result. This is an illustrative scenario, not a personalized recommendation or a current quote.
- Projected annual wages: 95000
- Filing status: Single
- Projected adjustments: 5000
- Deduction method: 2026 standard deduction
- Projected nonrefundable credits: 0
- Federal tax withheld to date: 7000
- Pay periods remaining: 10
- Current federal withholding per paycheck: 450
Example result: $397.00. Estimated amount to withhold per remaining paycheck to bring total federal withholding close to the calculated 2026 regular federal income tax.
Calculation used: ($10,970.00 estimated tax − $7,000.00 withheld to date) ÷ 10
How to interpret this example
This is a remaining-paycheck planning amount based on the entered tax estimate and withholding so far. Recalculate if income or the number of remaining checks changes. It is not a replacement for completing the applicable withholding form correctly.
