Suppose you set your 401(k) contribution high in January. By late September, you’ve reached the annual limit. Paychecks get larger, and your retirement saving for the year is done.
Your employer’s match may not be done on the same schedule.
Two Clocks, One Account
The IRS measures what you contribute from your own pay on an annual clock. For 2026, the employee deferral limit is $24,500. Your employer’s match can run on a different clock. Some plans calculate it each pay period, based on what you contributed from that paycheck. Others calculate it once a year, on the full year’s pay and contributions.
Plans differ, and the answer is in the plan documents. If the match is calculated per paycheck, a paycheck with no employee contribution can carry no match.
What Finishing Early Can Cost
Take a hypothetical plan with these assumptions. Salary is $156,000, paid over 26 pay periods, so $6,000 gross per paycheck. The employer matches 100% of the first 4% you contribute, which is $240 per paycheck. The match is calculated separately each pay period, and the plan has no true-up.
To reach $24,500 in 20 paychecks, you would contribute $1,225 each time, or about 20.42% of pay. A flat 20% election would reach only $24,000. After paycheck 20, your contributions stop, and so does the match. Six paychecks at $240 is $1,440.
That figure is the difference between two contribution schedules under this one hypothetical plan, and it applies only to that plan. The example assumes no additional matching caps and excludes vesting, catch-up contributions, and bonuses.
When the Employer Makes Up the Difference
I don’t see anything inherently wrong with maxing out a 401(k) early. But I wouldn’t treat finishing early as an accomplishment in itself. What matters is whether the contribution schedule allows you to receive the full employer match available under the plan. Saving more aggressively shouldn’t mean leaving part of your compensation behind.
Two plan designs can protect you. The first calculates the match on your full-year pay and contributions, so finishing early does not necessarily reduce the annual match. The second calculates the match per paycheck but includes a true-up, which is a later contribution that closes the gap between what was deposited and what the annual calculation would have produced.
The two can produce similar results, but they are different mechanisms. A true-up may also be deposited after year-end, so a missing match in October is not necessarily a permanent shortfall.
What to Look For in the Plan Document
Start with the Summary Plan Description, which your plan administrator can provide. Find the exact matching formula, then look for four things:
- The period over which the match is computed: per paycheck, quarterly, or annually.
- Whether the plan includes a true-up, and when it is deposited.
- Any cap on the match, in dollars or as a percentage of pay.
- Any eligibility or employment conditions, such as being employed on the last day of the year.
What Can Still Change
For 2026, the question is whether your plan matches annually or provides a true-up. If it does either, the pattern may cost you nothing. If it does neither, contributions you’ve already missed may not be recoverable under the plan’s matching formula.
For 2027, you can test the schedule before the year begins. Using the same hypothetical and the 2026 contribution limit for illustration:
- Front-loaded: $24,500 over 20 paychecks, with up to $1,440 in matching contributions potentially missed.
- Spread across the year: $24,500 over 26 paychecks, roughly $942.31 each, which keeps all 26 matching opportunities under this formula.
Both schedules put the same $24,500 of your pay into the plan, but the employer contribution differs because of timing.
Match rules also matter when you change jobs, including waiting periods and forfeited employer contributions, which I covered in The Financial Question Behind the Career Question. Check what your payroll system accepts before planning around a number. Some accept whole percentages only, and others allow dollar amounts or fractional percentages. Bonuses and variable pay may also be treated differently for matching purposes.
Does your employer calculate its match on the same annual schedule you use to plan your contributions?
FAQ
Can I still receive an employer match after I’ve maxed out my 401(k)?
It depends on the plan. Some plans calculate the match on annual pay and contributions, and some add a true-up after year-end. In a per-paycheck plan with no true-up, matching generally stops when your contributions stop.
What is a true-up contribution?
A true-up is an additional employer contribution that brings your total match up to what an annual calculation would have produced. Not every plan offers one, and it may be deposited after the plan year ends.
Does the employer match count toward the $24,500 limit?
No. That limit applies to your own elective deferrals. Employer contributions fall under a separate overall limit on total additions to your account, which is $72,000 for 2026, excluding catch-up contributions.
Does my plan calculate the match per paycheck or annually?
Start with the Summary Plan Description and look for the matching formula and the period over which it is calculated. If the language is unclear, ask your plan administrator to confirm how the match works.
