25d — Total Federal Income Tax Withheld Updated for tax year 2025

What this line means

The sum of all federal income tax withheld from all sources — W-2 withholding (25a), 1099 withholding (25b), and other withholding (25c). This is the total amount of federal tax already paid to the IRS on your behalf during the year through paycheck deductions and other withholding. It is the first component of your total payments on line 33.

Does this apply to you?

• Every filer who had federal income tax withheld from any source completes this line
• This is a simple addition: line 25a + 25b + 25c
• If you only have W-2 withholding, this equals line 25a

Easy to overlook

Your withholding is not your tax bill Many filers treat their total withholding as if it represents their actual tax. In reality, withholding is an estimate your employer made based on your W-4. If you changed jobs, got married, had a child, or took on freelance work, your withholding may be too high or too low. The difference shows up as a refund or balance due. ¹ [SOURCE: General filing pattern — withholding shortfall detection]

Withholding from all sources counts Line 25d is not just W-2 withholding. Tax withheld from pensions, Social Security, unemployment, and investment accounts all count as payments. Retirees who have withholding from multiple sources (pension, Social Security, IRA distributions) sometimes miss one and end up owing more than expected. ² [SOURCE: IRS Form 1040 instructions — Line 25d computation]

Watch out for this

Entering your total withholding on this line without verifying it against your actual W-2s and 1099s. The IRS matches every withholding claim against the forms they received from your employers and payers. If you claim more withholding than what was reported, the IRS will reduce your refund and send a notice explaining the adjustment.
