A 401(k) match is money your employer deposits into your retirement account based on how much you contribute from your own paycheck. If you don't contribute, you usually get no match, and the match itself never reduces your take-home pay.
This guide explains common 401k match formulas, how to figure out the contribution that gets you the full match, how vesting works, and what the match looks like next to your paycheck in 2026.
What a 401k match is
A match is an employer contribution tied to yours. Your plan sets a formula, such as "50% of what you contribute, up to 6% of your pay." Each payday, or sometimes once a year, the employer adds its share to your account.
Employer matching contributions:
- Don't come out of your paycheck, so your take-home pay is the same with or without them.
- Aren't included in your taxable wages for the year. You generally pay income tax on them when you withdraw the money.
- Don't count toward your $24,500 employee deferral limit for 2026.
Not every employer offers a match, and employers can change or suspend their formula. Your plan's summary plan description spells out the current rules.
Common match formulas
Here's how a few typical formulas work if you earn $2,666.67 per paycheck. The dollar amounts are per paycheck.
| Formula | You contribute to get full match | Employer adds |
|---|---|---|
| 100% of the first 3% of pay | 3% ($80.00) | 3% ($80.00) |
| 50% of contributions up to 6% of pay | 6% ($160.00) | 3% ($80.00) |
| 100% of the first 6% of pay | 6% ($160.00) | 6% ($160.00) |
Notice the first two formulas both give you 3% of pay in employer money, but the second one requires you to put in twice as much to get it. That's why reading the exact wording matters. Some employers use tiered formulas, such as 100% on the first few percent and 50% on the next few.
Worked example: 401k match on a $64,000 salary in North Carolina
A head of household filer in North Carolina earns $64,000 and is paid semimonthly (24 paychecks of $2,666.67). Her plan matches 50% of her contributions up to 6% of pay. Here are three choices, estimated with the PaycheckHubs paycheck calculator for 2026.
| Per paycheck | Contribute 0% | Contribute 3% | Contribute 6% |
|---|---|---|---|
| Her 401(k) contribution | $0.00 | $80.00 | $160.00 |
| Employer match | $0.00 | $40.00 | $80.00 |
| Total into account | $0.00 | $120.00 | $240.00 |
| Federal income tax | $184.50 | $174.90 | $165.30 |
| North Carolina income tax | $85.20 | $82.01 | $78.82 |
| Take-home pay | $2,192.97 | $2,125.76 | $2,058.55 |
At 6%, $240 goes into her account each payday, but her take-home pay is only $134.42 lower than if she contributed nothing. Over a year, that's $5,760 in total contributions ($3,840 from her and $1,920 from her employer) for about $3,226 less take-home pay.
Going from 3% to 6% costs her $67.21 per paycheck in take-home pay and adds $120 per paycheck to her account. Contributing less than 6% means leaving part of the match unclaimed.
Social Security and Medicare are the same in every column ($165.33 and $38.67), because traditional 401(k) contributions don't reduce FICA wages. See how a 401(k) affects take-home pay for the full breakdown.
Vesting: when the match is really yours
Your own contributions are always 100% yours. The employer's match may "vest" over time, meaning you earn ownership of it gradually or after a set period. If you leave before you're fully vested, you can lose the unvested part.
| Vesting type | How it works | Longest schedule allowed for matches |
|---|---|---|
| Immediate | Match is yours right away | Not applicable |
| Cliff | 0% until a set date, then 100% | 3 years of service |
| Graded | Ownership rises each year | Fully vested by 6 years of service |
If you're thinking about changing jobs, check your vesting status on your plan's website first. A few months can make a difference. Our guide to comparing job offers covers how to weigh a match and its vesting when you're choosing between employers.
Things that can cost you match money
Hitting the limit early
If you contribute a high percentage and reach the $24,500 limit before December, your contributions stop. If your employer matches per paycheck and has no year-end "true-up," you can miss the match on those final paychecks. Ask HR whether your plan does a true-up. More on the limit in 401(k) contribution limits for 2026.
Waiting periods
Some plans make new hires wait before they can contribute or before the match starts. Many plans now enroll new employees automatically at a default rate, which may be below the rate needed for the full match.
What counts as "pay"
Plans define the pay the match is based on. Some include bonuses and overtime, others use base salary only. The definition is in your plan documents.
Checking your match on your pay stub
Your contribution appears as a deduction on your pay stub. The employer match usually doesn't, or it shows as an informational line that doesn't change your net pay. The surest way to confirm the match is to look at your 401(k) account statement or website, where employer contributions are listed separately. Our guide on how to read your pay stub explains the other lines.
To see how a different contribution rate would change your own paycheck, use the paycheck calculator or the North Carolina paycheck calculator and compare results side by side. Workers in other states can find theirs in the state calculator directory.
Frequently Asked Questions
Is a 401k match taxed?
Not when it's deposited. Traditional matching contributions and their growth are taxed as income when you withdraw them. If your plan offers Roth matching contributions, those are taxable in the year they're made.
Does the employer match count toward my 401(k) limit?
No. The $24,500 limit for 2026 covers only your own deferrals. Employer contributions fall under a separate, higher combined limit.
What happens to my match if I quit?
You keep your own contributions and any vested portion of the match. Any unvested employer money is forfeited back to the plan.
Does the match show up in my take-home pay?
No. The match goes straight into your retirement account, so your take-home pay is the same whether your employer matches or not.
