For 2026, the maximum salary your employer can use when calculating your 401(k) match is $360,000. That ceiling comes from Internal Revenue Code Section 401(a)(17), and it applies no matter what your total pay looks like: earn $450,000 and the matching formula still runs against $360,000, ignoring the last $90,000.1Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living The cap is one filter among several. Contribution ceilings, nondiscrimination rules for high earners, per-pay-period timing, and vesting schedules can all reduce the match that actually ends up in your account.
How the $360,000 Compensation Cap Works
The limit applies to compensation actually paid during the calendar year (or plan year, if the plan uses one). Your employment contract’s headline number doesn’t matter. What matters is the pay run through payroll. Once your year-to-date eligible compensation hits $360,000, the plan stops calculating matching contributions on anything you earn after that. If year-end bonuses push you over the line, matching stops mid-bonus.
The IRS adjusts this figure periodically for inflation, so it usually rises a bit each year. Employers police the cap tightly because the stakes are high: if a plan applies the match to compensation above the ceiling, the entire plan can lose its tax-qualified status, which harms every participant, not just the person over-matched.2Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans Most payroll systems shut off matching calculations automatically once the threshold is reached.
Which Pay Counts Toward the Cap
The $360,000 ceiling limits how much pay counts. Your plan document decides which types of pay count in the first place. Under the standard IRS-approved compensation definitions, salary, overtime, bonuses, commissions, shift differentials, and holiday pay are all included.3Fidelity. Plan Sponsor’s Guide to Compensation
Equity is where the surprises happen. Stock options, restricted stock units, and similar awards are almost always excluded from the compensation used for matching. Someone with a $200,000 base salary and $300,000 in equity may assume their package clears the cap, but the match typically runs against the $200,000 cash portion only. The Summary Plan Description your HR department can hand you spells out exactly which pay components your plan counts.4Charles Schwab. How Does a 401(k) Match Work?
One detail that trips people up: matching is calculated on gross pay, not take-home. Pre-tax deductions for health insurance and other benefits don’t reduce the compensation used in the matching formula. Gross salary of $150,000 with take-home of $130,000 after deductions still produces a match based on $150,000.
The Ceiling Above the Match: Total Contribution Limits
Even where the compensation cap allows a large match, a separate limit under Section 415(c) caps the combined total of your elective deferrals, employer matching, and any other employer contributions at $72,000 for 2026.5Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits Your own elective deferral limit is $24,500 for 2026.6Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 If you defer the full amount, $47,500 of room remains under the $72,000 ceiling for employer contributions. Most workers never approach this, but it matters if you have a generous profit-sharing plan on top of matching.
Catch-Up Contributions Raise the Ceiling
Workers age 50 and older can defer an extra $8,000 in 2026, lifting the personal deferral limit to $32,500 and the total additions limit to $80,000.1Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living
SECURE 2.0 added a higher catch-up tier for participants who turn 60, 61, 62, or 63 during the plan year. Those workers can contribute an extra $11,250 instead of $8,000, taking the personal deferral limit to $35,750 and the total additions ceiling to $83,250.6Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The higher amount disappears at 64, so the window is narrow.
Timing: Why Front-Loading Can Cost You Match Dollars
Most employers calculate and deposit matching contributions each pay period rather than once a year. That works fine unless you front-load your deferrals. If you hit the $24,500 personal limit by August and stop contributing for the rest of the year, your employer has nothing to match during those final months.
Here’s how the math breaks. Say your employer matches 50% of the first 6% you defer, and you earn $200,000. Your full-year match should be $6,000. But if you stop deferring in August because you’ve hit your personal cap, the match stops with you. Depending on how the per-period calculation runs, you could lose hundreds or thousands.
True-Up Contributions Fix the Timing Gap
Some plans include a true-up provision. At year-end, the employer recalculates the match using your full annual compensation and total annual deferrals, then deposits any shortfall.7Fidelity. How Does a 401(k) Match Work? Not every plan offers one. If yours doesn’t, spread deferrals evenly across pay periods so you’re always contributing enough to capture the full match.
The timing problem gets worse for people near the compensation cap. Once year-to-date pay crosses $360,000, additional compensation stops counting for matching. Front-load your deferrals on top of that and you can lose match money from two directions in the same year. A true-up reconciles both.
Extra Limits for Highly Compensated Employees
High earners face restrictions that can pull the effective match below what the compensation cap alone would suggest. The IRS treats you as a Highly Compensated Employee (HCE) if you earned more than $160,000 in the prior year, or if you owned more than 5% of the business at any point during the current or prior year.1Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living The $160,000 figure is the threshold for the 2026 plan year.8Internal Revenue Service. Identifying Highly Compensated Employees in an Initial or Short Plan Year
HCEs are subject to two annual nondiscrimination tests: the Actual Deferral Percentage (ADP) test and the Actual Contribution Percentage (ACP) test. Both compare average savings and matching rates of HCEs against everyone else. If rank-and-file participants don’t save enough as a group, the gap widens past IRS limits and the plan fails.
The most common fix is returning excess contributions to HCEs. Matched dollars you already saw in your account can be pulled back out. That’s how high earners sometimes discover the effective ceiling on their match sits below $360,000. Corrective distributions must go out within two and a half months after the plan year ends.9Internal Revenue Service. 401(k) Plan Fix-It Guide – The Plan Failed the 401(k) ADP and ACP Nondiscrimination Tests
Safe Harbor Plans Skip Nondiscrimination Testing
Many employers avoid the testing regime by adopting a safe harbor 401(k). Safe harbor plans are exempt from ADP and ACP testing, so HCEs can contribute and receive matches up to the statutory limits without worrying about corrective distributions.10Internal Revenue Service. Operating a 401(k) Plan
The tradeoff is a mandatory minimum employer contribution, in one of two forms:
- A safe harbor match of 100% on the first 3% you defer plus 50% on the next 2%, producing a 4% match if you defer at least 5%. An alternative version matches 100% of the first 4% deferred.
- A non-elective contribution of at least 3% of every eligible employee’s pay, whether or not the employee defers anything.
If your plan is a safe harbor design, the HCE restrictions don’t reach you. Check your Summary Plan Description or ask HR to confirm.
Vesting Decides What You Actually Keep
Receiving a match and owning a match are not the same. Your own contributions vest immediately. Employer matching contributions are subject to a vesting schedule that determines what you’d walk away with if you left. Federal law caps the longest schedules employers can use:11Internal Revenue Service. Issue Snapshot – Vesting Schedules for Matching Contributions
- Three-year cliff vesting: you own 0% of the employer match until you complete three years of service, then 100% at once.
- Six-year graded vesting: 20% after two years, then another 20% each year until you’re fully vested at six.
Many employers vest faster, and some vest matching contributions immediately. Safe harbor matching contributions must be 100% vested right away, another reason safe harbor plans favor employees.12Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards
Vesting deserves weight when you think about the “max” match. An employee earning $360,000 with a 6% match could pull in more than $21,000 in employer contributions in a single year. Leave at two years and eleven months under a cliff schedule and you forfeit all of it. When you’re weighing a job offer, the vesting terms on matching contributions matter as much as the percentage on the offer letter.
