For tax year 2026, most traditional and safe-harbor 401(k) participants can defer up to $24,500 from their pay, before any age-based catch-up. An employer match is a separate contribution: it does not use up that $24,500 employee limit, but it does count toward the account’s separate annual-additions limit. Your own salary deferrals are always fully vested; employer contributions may be subject to a vesting schedule, depending on the plan.
The key to understanding your personal maximum and match is to keep three things separate: the amount you defer, the total added to your account, and the portion of employer contributions you own if you leave. The figures below are for U.S. plans and tax year 2026. Your plan documents control the match formula and details such as eligible pay and credited service.

How much can I contribute to my 401(k) in 2026?
The basic employee elective-deferral limit is $24,500 for 2026 for most traditional and safe-harbor 401(k) plans. This is the limit on your own salary deferrals, not the total that can be deposited into your account. A plan can impose a lower limit, and IRS rules or plan testing can also restrict what a particular participant may defer.
The $24,500 limit applies across your traditional and Roth 401(k) salary deferrals combined. Choosing Roth treatment does not give you a second employee limit. If you defer money to more than one employer’s plan during the year, those deferrals are generally aggregated for the limit rather than receiving a fresh $24,500 allowance at each job. The Internal Revenue Service explains the current limits in its Retirement topics – 401(k) and profit-sharing plan contribution limits guidance.

2026 employee deferral and annual-additions limits
| Limit or contribution | 2026 amount | What it covers |
|---|---|---|
| Basic employee elective deferrals | $24,500 | Your traditional and Roth salary deferrals combined, subject to plan terms. |
| Regular age-50 catch-up | Additional $8,000 | For an eligible participant age 50 or older when the plan permits catch-ups. |
| Higher catch-up for ages 60–63 | Additional $11,250 | For a participant who turns 60, 61, 62, or 63 during 2026, in most traditional and safe-harbor 401(k) plans. |
| General annual-additions limit | $72,000 | Employee deferrals other than catch-ups, employer contributions, and forfeiture allocations; also limited to 100% of compensation. |
The table’s catch-up amounts are additional to the basic employee limit, if the plan allows them. The IRS lists an overall limit of $80,000 including the regular catch-up, or up to $83,250 for participants in the age-60-through-63 higher catch-up group. Catch-up contributions are excluded from the general $72,000 annual-additions cap. These limits are separate tests, not competing descriptions of one cap.
What is the difference between the employee limit and the account limit?
The employee limit caps your salary deferrals; the annual-additions limit caps a broader set of contributions credited to your account. That distinction matters when your employer contributes as well as when you do.

For 2026, the general annual-additions cap is the lesser of 100% of your compensation or $72,000, before catch-ups. It includes your employee deferrals other than catch-up contributions, employer matching contributions, employer nonelective contributions, and forfeiture allocations. A match therefore does not reduce the amount you may defer under the $24,500 employee limit, but it is part of the employer-inclusive account calculation.
Example: Suppose you defer $20,000 and your employer contributes $5,000 in matching and other employer contributions. The total of those amounts is $25,000 for the annual-additions calculation, while your own deferral remains $20,000 against the $24,500 employee limit. This illustration assumes no other additions and enough compensation; your plan’s actual contributions and eligibility rules may differ.

Someone who contributes the full $24,500 and also receives employer contributions should not assume the match is unlimited simply because the employee limit has not changed. The $72,000 overall cap and compensation ceiling still apply to annual additions. Catch-up contributions are handled separately under the applicable catch-up limit.
How does a 401(k) employer match work?
An employer match is a contribution made under a plan formula in connection with your deferrals. There is no universal match percentage or legal default formula that applies to every participant: the plan’s terms determine whether a match is offered, who qualifies, which pay counts, and how the contribution is calculated.
A traditional 401(k) plan may provide matching contributions, nonelective contributions, both, or neither; a traditional-plan match can be discretionary. Safe-harbor and SIMPLE 401(k) plans have required employer-contribution features, but the exact feature still depends on the plan type and its terms. Do not treat a familiar example such as “50% of the first 6%” as your employer’s promise unless your own plan documents say so.
What to check before estimating your match
- Match formula: Find the rate and the portion of your deferrals or pay to which it applies.
- Eligible compensation: The plan may define compensation differently from your headline salary. Check which pay items are included.
- Eligibility: Confirm when you can participate and when you become eligible for employer contributions.
- Calculation timing: Determine whether the plan calculates the match each paycheck or reconciles it over the year.
- Year-end true-up: Check whether the plan makes a year-end adjustment if your contributions varied during the year. Do not assume one is provided.
- Vesting: A deposit to the account and ownership of that deposit are not always the same thing in a traditional plan.
These details affect the practical value of the match. For example, a per-paycheck calculation and a year-end reconciliation can produce different results for someone who stops contributing early or reaches the annual deferral limit before the final pay period. The plan documents determine whether and how that reconciliation occurs. The IRS’s 401(k) plan overview and Operating a 401(k) plan guidance explain the broad plan categories, not an individual employer’s formula.

When am I fully vested in my 401(k) match?
Vesting is the share of an account balance that you own under the plan’s rules. Your employee salary deferrals are always 100% vested immediately. Employer contributions in a traditional 401(k) may vest over time; safe-harbor and SIMPLE 401(k) employer contributions are fully vested when made.
For traditional-plan matching contributions subject to the general minimum standards, IRS guidance describes two schedules that satisfy the minimum: three-year cliff vesting or six-year graded vesting. A plan may be more generous, including immediate vesting. The schedule below shows the minimum vested percentages for those two examples.

| 4 | 100% | 60% |
| 5 | 100% | 80% |
| 6 | 100% | 100% |
Under cliff vesting, the employee has no vested share of the employer match until completing three years of service, then becomes fully vested. Under graded vesting, ownership increases in steps, reaching full vesting after six years. These are general minimum schedule examples, not a substitute for the terms governing your plan. The service definition and method used to credit service matter, so check the plan’s provisions rather than relying only on a calendar-year count.
What happens to my employer match if I leave my job?
Your own salary deferrals remain fully vested when you leave. The vested portion of employer contributions is yours under the plan’s vesting rules; any unvested portion may not be yours to keep. The exact amount depends on the plan schedule and your credited service on the relevant date.

For example, under a six-year graded schedule shown above, a participant with four completed years would be at least 60% vested in matching contributions subject to that schedule. That does not mean every plan uses this schedule, or that every contribution is treated identically. A plan may vest faster, and safe-harbor or SIMPLE employer contributions are fully vested when made.
Before making decisions around a departure, check the benefits statement for vested and unvested balances, then confirm the calculation with the plan administrator. Ask how the plan counts service, whether any service from an earlier period is credited, and which schedule applies to each type of employer contribution. The IRS’s Issue Snapshot – Vesting schedules for matching contributions and its retirement-plan disclosure guidance describe the general rules; the plan’s disclosure documents provide the participant-specific schedule.

Start with your Summary Plan Description (SPD) and current benefits statement. The SPD should explain the plan’s contribution features and vesting provisions; the statement can show your account balance and, where provided, vested balance. If either document is unclear, ask the employer or plan administrator for the controlling plan terms and an explanation of your individual calculation.
- Find the match section. Look for the match rate, deferral threshold, eligible compensation definition, eligibility date, and any annual or per-paycheck calculation rules.
- Find the vesting section. Identify the schedule for each employer contribution type and the plan’s service-crediting method.
- Check your own account data. Compare your contributions, employer deposits, and vested amount on the benefits statement; raise discrepancies with the administrator.
- Estimate your annual limits separately. Track your employee deferrals across employers against the $24,500 limit, and account for employer additions under the separate annual-additions limit.
- Confirm plan-specific restrictions. Ask whether the plan permits catch-ups and whether any plan or testing limit changes the amount you may defer.
The IRS says plan disclosure documents contain the specific vesting schedule. Its materials explain general statutory limits and plan rules, but cannot tell you whether your employer makes a discretionary match, how your pay is defined, or how your service is credited. Those answers come from your plan documents and administrator.

What are the most common 401(k) limit and match mistakes?
Most confusion comes from treating the employee deferral limit, employer match, annual-additions cap, and vesting percentage as if they were one number. Keeping them distinct avoids several common planning errors.
- Assuming an employer match is guaranteed: Traditional-plan matches may be discretionary, and an employer can have no match. Confirm what your plan actually provides.
- Counting each job as a fresh deferral allowance: The $24,500 employee limit generally aggregates deferrals across plans. A job change does not automatically create another full limit.
- Forgetting the employer-inclusive cap: A match does not consume the employee deferral limit, but it counts toward annual additions.
- Assuming every deposited employer dollar is already yours: Traditional-plan employer contributions may be subject to vesting, even though employee deferrals are immediately fully vested.
- Using salary instead of plan-defined compensation: Eligible compensation can be defined by the plan, so a simple percentage-of-salary estimate may be wrong.
- Assuming a year-end true-up: The existence and terms of any reconciliation depend on the plan; verify before relying on it.
Which IRS sources explain the 2026 rules?
The 2026 figures and general rules here come from IRS materials: Retirement topics – 401(k) and profit-sharing plan contribution limits, Retirement topics – Catch-up contributions, 401(k) plan overview, Operating a 401(k) plan, Issue Snapshot – Vesting schedules for matching contributions, and IRS guidance on retirement-plan vesting and disclosure documents. The limit figures are for tax year 2026 and should not be assumed to apply in later years; the IRS can adjust limits. Individual match formulas, eligible compensation, and service-crediting rules remain plan-specific.

Frequently Asked Questions
Do years at a previous employer count toward my new 401(k) vesting schedule?
There is no single answer for every plan. Ask the new plan administrator whether the plan credits any earlier service and how it defines a completed year; the SPD and plan provisions control.
Can my 401(k) plan set a lower contribution limit than $24,500?
Yes. The IRS limit is a ceiling, not a promise that every participant can defer that much. Plan terms or applicable nondiscrimination testing can limit an individual’s deferrals.
Does a safe-harbor 401(k) match have the same vesting rules as a traditional match?
No. Safe-harbor employer contributions are fully vested when made, while traditional-plan employer contributions may follow a vesting schedule. Confirm the plan type and contribution source in the plan disclosures.
Does the 2026 401(k) limit apply to money I contribute to an IRA?
The figures in this article are specifically for 401(k) salary deferrals and annual additions. IRA contribution rules have separate limits and eligibility rules, so the 401(k) amounts should not be used as an IRA limit.
