The IRS is reminding taxpayers that checking tax withholding early in 2025 can help prevent costly surprises when filing their return in 2026. The agency recommends using its free online Tax Withholding Estimator, especially for those who recently filed their 2024 tax return.
What Is the IRS Tax Withholding Estimator?

The IRS Tax Withholding Estimator is a digital tool that helps employees, contractors, and retirees determine if they are having the right amount of federal income tax withheld from their paychecks. It accounts for all income sources, including:
- Wages
- Side jobs
- Retirement income
- 1099-K payments for goods or services
Using the tool can help avoid both a large tax bill and a large refund, aligning tax payments more closely with actual liability.
Why Use the Estimator in 2025?
The U.S. tax system is pay-as-you-go, meaning federal income taxes are due as income is earned. If too little is withheld, taxpayers may owe the IRS and face penalties. If too much is withheld, they’re giving the government an interest-free loan.
Reasons to use the estimator now:
- Adjust your Form W-4 before it’s too late in the year
- Increase take-home pay instead of waiting for a refund
- Prevent tax debt or penalties when filing in 2026
- Update withholding after life changes, like marriage, a new job, or having a child
What You’ll Need to Use It
Before using the IRS Tax Withholding Estimator, gather the following:
- Most recent pay stubs
- Last year’s federal tax return
- Information on all income sources, including a spouse’s if filing jointly
When to Update Your Withholding
The IRS recommends checking withholding at least once a year, ideally after filing a return or experiencing a significant life event. Updates can be made at any time by submitting a revised Form W-4 to your employer or adjusting estimated payments if self-employed.
Special Cases: When the Estimator Isn’t Enough
For taxpayers with complex financial situations—such as those subject to the alternative minimum tax, or those earning income through capital gains or qualified dividends—the IRS suggests reviewing Publication 505: Tax Withholding and Estimated Tax.
