401kEmployer Match & Vesting: The Tax Rules
Employer contributions aren't taxed when they're made — but vesting determines whether that money is actually yours to keep.
Reviewed January 2026 against current IRS guidance.
Employer contributions aren't taxed to you when made
Unlike your salary, an employer's matching or profit-sharing contribution to your 401(k) is not included in your taxable wages for the year it's contributed (unless it's specifically designated as a Roth employer contribution under a SECURE 2.0 plan option — see below). It grows tax-deferred, alongside your own traditional contributions, and is taxed as ordinary income when eventually withdrawn.
Vesting: the money can be conditional
Vesting is the schedule by which employer contributions become permanently yours. Your own contributions are always 100% vested immediately; it's the employer's money that can be subject to a waiting period.
Two common vesting schedule structures:
- Cliff vesting: 0% vested until a specific point (commonly 2 or 3 years of service), then 100% vested all at once.
- Graded vesting: an increasing percentage vests each year of service (for example, 20% per year over 5 years) until you're fully vested.
If you leave before you're fully vested, the unvested portion is forfeited back to the plan — it's simply not yours, and there's no tax consequence to you personally from the forfeiture since you never had a taxable claim to it.
Roth employer contributions (a SECURE 2.0 option)
SECURE 2.0 permits (but does not require) plans to let employees elect to have employer matching or non-elective contributions treated as Roth contributions instead of pre-tax. If your plan offers this and you elect it:
- The employer contribution amount is included in your taxable income for the year it's made, since you're choosing Roth tax treatment on money you didn't personally take home.
- Roth employer contributions must be fully vested immediately — a plan cannot subject a Roth-designated employer contribution to a vesting schedule.
- Once vested and aged appropriately, withdrawals of this money follow the same tax-free treatment as your own Roth contributions.
Does the match count toward your contribution limit?
No. Your personal elective deferral limit only counts money you choose to defer from your own pay. Employer contributions, including matching, count toward the separate and much higher overall (Section 415) limit described on the contribution limits page — they don't reduce how much you personally can contribute.
