No. A traditional employer 401(k) match does not count as taxable income in the year it’s deposited into your account. The money goes into a qualified trust that is exempt from current taxation, so it never shows up in your gross income for that year. You will owe ordinary income tax on the match later, when you withdraw it in retirement, at whatever rate applies to you in the year of the distribution.1Office of the Law Revision Counsel. 26 USC 402 Taxability of Beneficiary of Employees Trust
That “now versus later” split is the whole point of the deferral. The full match stays invested and compounds without being reduced by an immediate tax bill, and you don’t report any of it on your annual federal income tax return for the year it was contributed.
The Match Isn’t Hit by Payroll Taxes Either
The exclusion goes beyond federal income tax. Employer matching contributions are also exempt from Social Security and Medicare (FICA) withholding at the time of contribution.2Internal Revenue Service. Retirement Plan FAQs Regarding Contributions – Are Retirement Plan Contributions Subject to Withholding for FICA, Medicare or Federal Income Tax Your own pre-tax deferrals are treated differently: those still get hit with FICA even though they escape federal income tax.
The practical result is that a match costs you nothing in payroll taxes. Your take-home pay is the same whether or not your employer offers one, because the contribution is funded entirely by the employer and sits outside your taxable compensation.
Why the Match Isn’t on Your W-2
A lot of people go looking for the match on their W-2 at tax time and can’t find it. That’s expected. Your own pre-tax 401(k) deferrals appear in Box 12 with Code D, but because the employer match is not treated as taxable compensation, the IRS does not require employers to report it on the W-2 at all.2Internal Revenue Service. Retirement Plan FAQs Regarding Contributions – Are Retirement Plan Contributions Subject to Withholding for FICA, Medicare or Federal Income Tax
To find the exact amount your employer contributed, check two places:
- Your final pay stub of the year. Most employers include a year-to-date summary of employer-paid benefits, including 401(k) matching, on December pay stubs.
- Your quarterly retirement account statements. Your plan provider separates employee contributions from employer contributions, so you can see exactly what the company added under the matching formula.
How the Exclusion Affects AGI and Tax Benefits
Because a traditional match is left out of your gross income, it doesn’t raise your adjusted gross income (AGI). AGI and modified AGI (MAGI) are the gatekeepers for a range of tax benefits, and keeping the match out of that calculation has real downstream effects.
Roth IRA eligibility is one example. Your ability to contribute to a Roth IRA phases out based on MAGI, and for 2026 the phase-out runs from $153,000 to $168,000 for single filers and $242,000 to $252,000 for married couples filing jointly.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 A generous employer match will not push you across those thresholds, because the match isn’t in MAGI to begin with.
The Saver’s Credit works the same way. That credit is worth up to 50% of your own retirement contributions if you fall under the income limits, which for 2026 are $80,500 for married couples filing jointly, $60,375 for heads of household, and $40,250 for single filers.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The employer match doesn’t count against those income limits, and the credit itself is calculated on your own contributions, not the employer’s.
The same logic protects your position on the Earned Income Tax Credit and the student loan interest deduction, both of which use AGI or MAGI to phase out benefits.4Internal Revenue Service. Earned Income and Earned Income Tax Credit (EITC) Tables
The One Exception: Roth-Designated Matches
Starting in late 2022, the SECURE 2.0 Act gave plans the option of letting employees designate the employer match as a Roth contribution. If your plan offers this and you elect it, the tax treatment changes.
A Roth-designated match still isn’t subject to federal income tax withholding, and generally not to Social Security or Medicare withholding either. But it must be reported on Form 1099-R (not Form W-2) for the year it’s allocated to your account, and the amount is included in your income for tax purposes in that year even though no withholding is taken from your paycheck.5Internal Revenue Service. SECURE 2.0 Act Impacts How Businesses Complete Forms W-2 The trade-off is on the back end: qualified withdrawals from the Roth account are generally tax-free in retirement.
Not every plan offers Roth-designated matching. Ask your plan administrator whether this option is available before assuming it applies to you.
When a Match Can Become Taxable
The one situation where an employer match ends up in your taxable income sooner than retirement is a corrective distribution. Total annual additions to your 401(k) — your deferrals, the employer match, and any profit-sharing — cannot exceed $72,000 for 2026, or 100% of your compensation, whichever is less.6Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living If the total goes over, the plan must return the excess to bring the account back into compliance.7Office of the Law Revision Counsel. 26 USC 415 Limitations on Benefits and Contribution Under Qualified Plans
That corrective distribution gets reported on Form 1099-R and must be included in your income for the year of the distribution. It is not subject to the 10% additional tax that usually applies to withdrawals before age 59½, and it cannot be rolled into another retirement account.8Internal Revenue Service.

The risk is highest for people contributing to 401(k) plans at two different employers in the same year. Neither plan administrator can see what you’re doing at the other one, so tracking your combined contributions against both the $24,500 elective deferral limit and the $72,000 total additions limit is on you.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Barring that kind of overage, the match you see on your statement each year is money you won’t owe tax on until you withdraw it.
