What Does a 6% 401(k) Match Mean? Vesting, Taxes, and True-Up

A 6% 401(k) match means your employer will contribute to your retirement account based on up to 6% of your gross pay, but only if you put in enough of your own money to earn it. On a $60,000 salary, a full dollar-for-dollar match at 6% adds $3,600 a year to your account on top of what you contribute yourself. The exact dollar figure depends on the formula your plan uses, and you won’t fully own the employer’s money until you’ve worked there long enough to vest.

How Much Your Employer Actually Puts In

The “6%” is a ceiling tied to your salary, not a promise of 6% of your pay in free money. What lands in your account depends on which of three formulas your plan uses.

Dollar-for-Dollar Match

A dollar-for-dollar (or 100%) match up to 6% means the employer contributes the same amount you do, capped at 6% of your gross pay. Earn $60,000 and contribute 6% ($3,600), and your employer also contributes $3,600, for a combined $7,200 that year before any investment growth. Contribute only 4%, and the match also stops at 4%.

Partial Match

A partial match pays a fraction of each dollar you defer. A common version is 50 cents on the dollar up to 6% of salary. On $60,000, contributing the full 6% ($3,600) earns $1,800 from the employer. You still have to contribute the full 6% to collect the full match; anything less leaves money on the table.

Tiered Match

A tiered formula changes the match rate at different contribution levels. One example: 100% on the first 3% you contribute, then 50% on the next 3%. On a $60,000 salary, deferring the full 6% ($3,600) yields $1,800 from the first tier plus $900 from the second, for $2,700 total.

Whether Bonuses and Commissions Count

Some plans calculate the match on base pay only; others include bonuses, overtime, and commissions. The definition lives in your plan’s Summary Plan Description, and it directly changes how many dollars the “6%” turns into. If a big chunk of your income is variable, this detail matters.

You Have to Contribute to Get It

The match is not a flat gift. If you contribute 0%, you get 0% from the employer. If you contribute 3% under a dollar-for-dollar formula capped at 6%, you get 3%. To capture the full match, your own deferral has to meet or exceed the 6% threshold.

The Front-Loading Trap

If you set your deferral high enough to hit the annual IRS contribution limit before December, most payroll systems stop withholding from your paycheck for the rest of the year. No deferral means no match on those final paychecks. Someone earning $120,000 who contributes 20% per paycheck will hit the 2026 employee deferral limit of $24,500 around mid-year 1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 and forfeit matching dollars on every remaining pay period.

True-Up Provisions

Some plans fix this with a true-up. After year-end, the employer recalculates what your match should have been based on your full-year salary and total deferrals, then deposits any shortfall, usually in the first quarter of the following year. Not every plan has one. If yours doesn’t, the safest move is to spread your contributions evenly across every pay period so you earn the match on each paycheck.

When the Match Actually Becomes Yours

Your own contributions are 100% yours from the moment they go in. The employer match is different: it often comes with a vesting schedule, which is the length of service required before you fully own those dollars.

Cliff Vesting

Under cliff vesting, you own 0% of the match until you hit a set service milestone, then jump to 100%. Federal law caps this cliff at three years for 401(k) plans. 2Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards Leave at two years and eleven months, and you lose the entire match.

Graded Vesting

Graded vesting gives you ownership in steps. The maximum federal schedule for a 401(k) is:2Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards

  • 2 years: 20% vested
  • 3 years: 40% vested
  • 4 years: 60% vested
  • 5 years: 80% vested
  • 6 years: 100% vested

Leave after four years, and you keep 60% of the match and forfeit the rest.

Immediate Vesting

Safe Harbor 401(k) plans require the match to vest immediately: you own 100% from day one. The exception is a plan using a Qualified Automatic Contribution Arrangement (QACA), which can impose up to a two-year cliff on safe harbor matching contributions. If your employer advertises “immediate vesting,” the match is yours no matter when you leave.

When You Can Start Getting the Match

The match doesn’t start on your first day. Federal rules let employers require you to reach age 21 and complete up to one year of service before joining the plan.3Internal Revenue Service. 401(k) Plan Qualification Requirements Plans that vest everything 100% immediately can push the service requirement to two years. The match starts flowing once you’re enrolled and your own deferrals begin.4U.S. Department of Labor. FAQs About Retirement Plans and ERISA

Long-term part-time workers also become eligible to defer, and therefore to collect any match, after completing at least 500 hours of service in two consecutive years and reaching age 21.

Watch the Auto-Enrollment Default

Many plans now enroll you automatically at a default contribution rate, and plans established after December 29, 2022 generally must do so starting in 2025. A Qualified Automatic Contribution Arrangement starts you between 3% and 10%, then raises the rate by 1% a year until it reaches between 10% and 15%.5Internal Revenue Service. Retirement Topics – Automatic Enrollment If your plan’s default is 3% and your employer offers a 6% match, you’re collecting only half the available match until auto-escalation catches up, which can take years. Check your rate right after enrollment and move it to at least 6% if you want the full match now.

How the Match Is Taxed

For a traditional (pre-tax) 401(k), the employer match is not taxable income the year it’s deposited; it doesn’t appear on your W-2.6Internal Revenue Service. 401(k) Plan Overview The money grows tax-deferred and is taxed as ordinary income when you withdraw it in retirement.

SECURE 2.0 allows employers to deposit matching contributions into a designated Roth account if you elect it and the plan offers the option. A Roth match is included in your taxable income for the year it’s allocated, and no federal tax is withheld from the contribution itself, so you may need to adjust your withholding or make estimated payments. The payoff is tax-free qualified withdrawals later.

One figure worth knowing: the employer match does not count against the $24,500 employee deferral limit for 2026. It falls under a separate overall ceiling of $72,000 on all contributions to your account that year under Section 415(c).7Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living For most workers earning a 6% match, that combined ceiling is nowhere near binding.
