401(k) Contribution Limits 2025 and 2026: The Complete IRS Guide
2026 limits officially confirmed (IRS Notice 2025-67): The IRS announced 2026 401(k) limits on November 13, 2025. The employee deferral limit rises to $24,500 (up $1,000 from 2025). The standard catch-up for ages 50–59 and 64+ increases to $8,000. The SECURE 2.0 super catch-up for ages 60–63 holds at $11,250. A new 2026 rule requires high earners ($150K+ in 2025 FICA wages) to designate all catch-up contributions as Roth. See IRS.gov for official source documents.
The IRS 401(k) contribution limits for 2025 are officially updated, affecting traditional 401(k), Roth 401(k), and Solo 401(k) retirement plans. Whether you want to maximize your retirement savings, understand employer match rules, or prepare for the projected 2026 limits, this complete guide explains everything you need to know. We cover annual contribution limits, catch-up contributions, employer contributions, withholding rules, and the latest IRS updates that impact employees, self-employed professionals, and business owners.

What Is the Maximum 401(k) Contribution for 2025?
The IRS sets two separate limits every American worker needs to understand.
Limit 1 — Employee Elective Deferrals: The cap on how much you personally can contribute from your paycheck — whether pre-tax (traditional) or after-tax (Roth). For 2025, that number is $23,500. Pre-tax contributions reduce your taxable income today; if you want a full breakdown of how 401(k) contributions are treated at tax time, see our 401(k) tax form guide.
Limit 2 — Total Annual Additions: The combined ceiling for everything going into your account — your contributions, your employer’s match, profit-sharing, and any after-tax contributions. For 2025, the total cap is $70,000 (or 100% of your compensation, whichever is lower).
Most employees only need to track the first number. The second becomes relevant for business owners, the self-employed, and those with unusually generous employer profit-sharing plans.
2025 401(k) Contribution Limits — Official IRS Reference Table
Source: IRS Notice 2024-80 (2025 limits) & IRS Notice 2025-67 (2026 limits)
Pre-tax & Roth employee deferrals: $23,500 (2025) → $24,500 (2026)
Employee + employer combined ceiling: $70,000 (2025) → $72,000 (2026)
Standard catch-up (50–59 or 64+): $7,500 (2025) → $8,000 (2026)
Super catch-up (60–63): $11,250 (2025) → $11,250 (2026, no change)
IRA contribution limit (under 50): $7,000 (2025) → $7,500 (2026)
IRA contribution limit (50+): $8,000 (2025) → $8,600 (2026) — catch-up increases from $1,000 to $1,100 in 2026
401(k) Catch-Up Contribution Limits 2025 (Age 50+)
If you turn 50 at any point during 2025, you are immediately eligible for catch-up contributions. The 401(k) catch-up 2025 amount is an additional $7,500 on top of the $23,500 standard limit — bringing your personal ceiling to $31,000. So what is the 401(k) limit for 2025 if you’re over 50? It’s $31,000 — not the standard $23,500. Many participants search for “401k catch up 2025” rules specifically — this additional $7,500 is available the calendar year you turn 50.
Congress created catch-up contributions specifically so workers approaching retirement can accelerate savings during their peak earning years. This applies equally to both traditional (pre-tax) and Roth 401(k) contributions, or any combination of the two.
401(k) Contribution Limits 2025 Over 50
Workers aged 50–59 or 64 and older can contribute a total of $31,000 to their 401(k) in 2025 — the $23,500 base limit plus the $7,500 catch-up. In 2026, this rises to $32,500 ($24,500 + $8,000). You become eligible the calendar year you turn 50, even if your birthday falls on December 31.
The SECURE 2.0 “Super Catch-Up”: Ages 60–63
This is one of the most important recent changes that most workers haven’t heard about yet. The The SECURE 2.0 Act of 2022 created an enhanced catch-up contribution exclusively for a four-year age window.
If you are age 60, 61, 62, or 63 at any point during 2025, and your plan allows it, your catch-up contribution is $11,250 — not $7,500 — making your total employee contribution ceiling $34,750.
401(k) Contribution Limits 2025 Over 60
For workers aged 60, 61, 62, or 63 specifically, the SECURE 2.0 “super catch-up” provision allows a total employee contribution of $34,750 in 2025 and $35,750 in 2026 — significantly more than the standard catch-up available to those over 64. At age 64, you revert to the standard catch-up amount ($7,500 in 2025, $8,000 in 2026). This makes the 60–63 window one of the most valuable savings opportunities in the tax code.
⚠️ Super Catch-Up Key Details — Confirm with Your Plan
The super catch-up is the greater of $10,000 or 150% of the regular catch-up. For 2025: 150% × $7,500 = $11,250.
This applies only to ages 60–63. At age 64, you revert to the standard $7,500 catch-up.
Your employer plan must opt in — not all plans have adopted this provision yet. Always confirm with your HR or plan documents before relying on this limit.
This benefit is available for both traditional and Roth 401(k) contributions.
✎ Example: Ages 60–63 Super Catch-Up Opportunity
The ages 60–63 window is a narrow but meaningful opportunity — an extra $3,750 per year compared to the standard catch-up.
Over four years at a 7% average return, that additional $15,000 in contributions could compound to over $22,000 by traditional retirement age.
At age 64 the super catch-up window closes and you revert to $7,500 — making 60–63 a particularly valuable savings opportunity that should not be missed.
Does the 401(k) Limit Include Employer Match?
No. The most common question we hear is: does 401(k) limit include employer match? Or more fully: does the 401(k) limit include employer match contributions from your company? The answer is no — your $23,500 employee deferral limit is entirely separate from anything your employer contributes. The two are tracked independently. Similarly, do employer contributions affect 401(k) limit calculations for your personal deferrals? They do not reduce your personal deferral room at all.
Your employer’s match counts toward the broader $70,000 combined limit — but it does not reduce how much you can personally put in.
✎ Worked Example (2025)
Your salary: $100,000
Your contribution: $23,500 (full employee limit)
Employer match: 4% of salary = $4,000
Total account additions: $27,500
Remaining room under $70,000 cap: $42,500 (for after-tax contributions, if your plan allows)
Employer contributions count toward the $70,000 combined ceiling but leave your $23,500 personal deferral room completely intact. The only scenario where employer contributions create a problem is if combined contributions somehow approach the $70,000 cap — which typically only occurs in high profit-sharing arrangements.
Roth 401(k) Contribution Limits 2025 and 2026
The Roth 401(k) follows identical contribution limits to the traditional 401(k). There is no separate, lower limit.
Roth 401(k) limit for 2025: $23,500 (or $31,000 / $34,750 with applicable catch-up). Roth 401(k) limit for 2026: $24,500 (or $32,500 / $35,750 with catch-up). If you have access to both a traditional 401(k) and a Roth 401(k) through your employer, you can split contributions between them freely — but the combined total across both cannot exceed your applicable annual limit.
| Traditional 401(k) | Roth 401(k) | |
|---|---|---|
| Contributions | Pre-tax — reduces taxable income today | After-tax — no deduction now |
| Investment growth | Tax-deferred | Tax-free |
| Withdrawals in retirement | Taxed as ordinary income | Tax-free |
| Best suited for | Expect lower tax rate in retirement | Expect higher tax rate in retirement |
| Income limits | None | None (unlike Roth IRA) |
| Required Minimum Distributions | Yes, starting age 73 | No longer required (post-SECURE 2.0) |
The biggest advantage of the Roth 401(k) over a Roth IRA: no income limits. Even if you earn $300,000 a year, you can still contribute to a Roth 401(k). In 2025, the Roth IRA phases out for singles above $150,000 and married filers above $236,000 — making the Roth 401(k) the primary Roth vehicle for high earners.
Individual 401(k) / Solo 401(k) Contribution Limits 2025 and 2026
If you’re self-employed — sole proprietor, independent contractor, freelancer, or single-member LLC — the Solo 401(k) (also called an Individual 401(k) or Self-Employed 401(k)) is the most powerful retirement savings vehicle available to you. The individual 401(k) contribution limits mirror the standard 401(k) rules, but with an added employer profit-sharing layer since you’re both employer and employee.
Solo 401(k) / Individual 401(k) Contribution Rules — 2025 & 2026
As the “employee”: Defer up to $23,500 (2025) or $24,500 (2026) from your business income (or up to $31,000 / $32,500 with standard catch-up, or $34,750 / $35,750 with super catch-up) — identical to any W-2 employee’s limit.
As the “employer”: Make profit-sharing contributions of up to 25% of your net self-employment income (after deducting half of your self-employment tax and the contribution itself from net earnings).
Combined maximum 2025: $70,000 (or $77,500 / $81,250 with catch-up, depending on age).
Combined maximum 2026: $72,000 (or $80,000 / $83,250 with catch-up, depending on age).
IRS compensation cap: The IRS limits the amount of compensation that counts toward retirement contribution calculations — $350,000 in 2025 and $360,000 in 2026. Even if you earn more, only this amount is used to determine your profit-sharing contribution.
Tax note: Use IRS Publication 560 or a tax professional for the precise net SE income calculation — it is more nuanced than it appears.
✎ Solo 401(k) 2025 Contribution Example
Net self-employment income: $150,000
Employee deferral: $23,500
Employer profit-sharing (approx. 20% of net SE income after adjustments): ~$28,000
Total: ~$51,500 — comfortably under the $70,000 cap. For self-employed earners above $200,000, it is possible to hit the $70,000 ceiling entirely within a Solo 401(k). No other retirement account offers this capacity for the self-employed.
How Much Can I Contribute to My 401(k)?
Your limit depends on three factors: your age, your compensation, and your plan’s specific rules.
| Situation | Your 2025 Limit |
|---|---|
| Under age 50 | Up to $23,500 (or total compensation, whichever is less) |
| Age 50–59 or 64+ | Up to $31,000 |
| Age 60–63 (if plan allows) | Up to $34,750 |
| Multiple 401(k)s at different employers | Total employee deferrals still capped at $23,500 across all plans |
⚠️ Multiple Employer Plans: Important Rule
If you work two jobs simultaneously and both offer 401(k)s, your personal $23,500 deferral limit applies in total across all plans combined — not per plan.
However, the $70,000 combined limit (employee + employer) applies separately to each plan. This distinction matters most if you have a Solo 401(k) alongside an employer plan.
What Happens If You Contribute Too Much to a 401(k)?
Overcontributing is called an excess deferral, and the IRS handles it with a double-tax penalty.
⚠️ Excess Deferral Consequences — Avoid This
The consequence: Excess contributions are taxed as ordinary income in the year they were made — and then taxed again when you withdraw them in retirement. This double taxation is entirely avoidable.
Common causes: switching jobs mid-year across two plans; holding both an employer 401(k) and a Solo 401(k); administrative error at your plan provider.
The fix: Request a corrective distribution of the excess (plus any earnings) by April 15 of the following tax year. Your plan administrator processes this and you’ll pay income tax on the earnings — but you avoid double taxation. The excess is reported on Form 1099-R. Miss the April 15 deadline and the excess is taxed in both the contribution year and the withdrawal year — with no exception.
How to Max Out Your 401(k) in 2025
Maxing out at $23,500 requires contributing roughly $1,958 per month, or about $904 per biweekly paycheck (26 pay periods).
After-Tax 401(k) Contributions and the Mega Backdoor Roth
Beyond the $23,500 employee deferral limit, some plans allow additional after-tax (non-Roth) contributions up to the $70,000 combined ceiling. This creates the opportunity for a powerful strategy called the Mega Backdoor Roth.
Mega Backdoor Roth: How It Works
Step 1: Make after-tax contributions to your 401(k) beyond the $23,500 pre-tax/Roth cap.
Step 2: Convert those after-tax contributions to Roth — either through an in-plan Roth rollover or by rolling them to a Roth IRA upon leaving the plan.
Result: Tax-free growth on a pool of money far larger than a standard Roth 401(k) or Roth IRA allows.
2025 Example: You contribute $23,500 (pre-tax/Roth) + employer contributes $10,000 + you add $36,500 in after-tax contributions = $70,000 total. You then convert the $36,500 after-tax portion to Roth.
2026 Example: You contribute $24,500 + employer contributes $10,000 + you add $37,500 in after-tax contributions = $72,000 combined limit. The $37,500 after-tax portion converts to Roth.
Not all plans permit after-tax contributions or in-plan conversions. Check your Summary Plan Description or ask HR directly.
401(k) Contribution Limits and IRAs: Are They Connected?
No — they are completely independent. Maxing your 401(k) has zero effect on your IRA contribution room.
| 2025 | 2026 | |
|---|---|---|
| Traditional or Roth IRA (under 50) | $7,000 | $7,500 |
| Traditional or Roth IRA (50+) | $8,000 | $8,600 |
In 2026, the IRA limit rises to $7,500 — the first increase since 2023. Note that the 50+ catch-up for IRAs also increases: from $1,000 additional in 2025 to $1,100 additional in 2026, bringing the total to $8,600. This means in 2026 you could potentially shelter $24,500 + $7,500 = $32,000 per year in tax-advantaged accounts if under 50, before factoring in employer contributions or catch-ups.
Roth IRA Income Phase-Out Limits: 2025 and 2026
2025 — Single filers: phase-out begins at $150,000, eliminated at $165,000.
2025 — Married filing jointly: phase-out begins at $236,000, eliminated at $246,000.
2026 — Single filers: phase-out begins at $153,000, eliminated at $168,000.
2026 — Married filing jointly: phase-out begins at $242,000, eliminated at $252,000.
If your income exceeds these thresholds, you cannot contribute directly to a Roth IRA — but you can still contribute to a Roth 401(k) with no income cap at all.
Max Employer Contribution to 401(k) and Employer Contribution Rules
Your employer’s contributions to your 401(k) are governed by separate rules from your own deferrals. Understanding these rules helps you maximize what you receive.
401(k) Employer Contribution Rules: Key Facts
Maximum employer contribution 2025: Employer contributions (match + profit-sharing) can bring the combined total up to $70,000 in 2025 and $72,000 in 2026 — but only your employee deferrals count toward those limits, not employer contributions alone.
Common match formulas: The most typical employer match is 50 cents per dollar up to 6% of salary, or dollar-for-dollar up to 3–4% of salary. These formulas vary widely by employer and plan.
Vesting schedules: Employer contributions are often subject to a vesting schedule — meaning you only keep the employer match if you stay employed for a set period. Common structures include cliff vesting (100% after 3 years) and graded vesting (20% per year over 6 years). Your own contributions are always 100% vested immediately.
Safe harbor plans: Some employers offer safe harbor 401(k) plans that require immediate 100% vesting on employer contributions in exchange for simplified IRS compliance testing.
Profit-sharing contributions: Beyond matching, employers can make discretionary profit-sharing contributions up to 25% of eligible payroll, subject to the $70,000 combined cap.
401(k) Income Limits: Does Your Salary Affect How Much You Can Contribute?
No — a 401(k) has no income limits for contributions. This is one of the most searched and most misunderstood questions about 401(k) plans. Unlike a Roth IRA (which phases out above $150,000 for singles in 2025), you can contribute the full $23,500 to a 401(k) whether you earn $40,000 or $400,000 a year. There are also no separate 401(k) withholding limits that cap your payroll deductions based on income — the only limit is the IRS annual deferral ceiling.
⚠️ 401(k) vs. Roth IRA: Income Limit Comparison
Traditional 401(k): No income limit to contribute. No income limit to deduct contributions (deduction is automatic for pre-tax deferrals).
Roth 401(k): No income limit to contribute — this is the primary advantage over a Roth IRA for high earners.
Roth IRA: Phase-out begins at $150,000 (single) / $236,000 (married filing jointly) in 2025. Above $165,000 / $246,000, you cannot contribute directly at all.
One caveat: Highly compensated employees (HCEs) — those earning over $155,000 in 2024 — may have their contributions limited if their plan fails nondiscrimination testing. Your plan administrator will notify you if this applies.
2025 Retirement Contribution Limits: 401(k), IRA, HSA and More
A 401(k) is one of several tax-advantaged accounts you can use simultaneously. Here is the complete picture of 2025 and 2026 retirement and savings contribution limits across all major account types.
| Account Type | 2025 Limit | 2026 Limit | Catch-Up (50+) |
|---|---|---|---|
| 401(k), 403(b), 457 — employee deferral | $23,500 | $24,500 | $7,500 (2025), $8,000 (2026) |
| 401(k) — ages 60–63 super catch-up | $11,250 | $11,250 | In place of standard catch-up |
| Traditional or Roth IRA | $7,000 | $7,500 | $1,000 extra (2025) / $1,100 extra (2026) |
| SEP-IRA (employer contribution) | $70,000 | $72,000 | No catch-up |
| SIMPLE IRA — employee deferral | $16,500 | $17,000 | $3,500 additional (50+) |
| HSA — individual | $4,300 | $4,400 | $1,000 additional (55+) |
| HSA — family | $8,550 | $8,750 | $1,000 additional (55+) |
Maximum tax-advantaged savings in 2025 (under age 50)
- Max out 401(k): $23,500
- Max out IRA: $7,000
- Max out HSA (family): $8,550
- Total: $39,050 per year in tax-advantaged accounts — before any employer match

| 2026 | $24,500 | $8,000 | $11,250 |
The employee deferral limit has increased by $5,500 over the last seven years. The introduction of the super catch-up in 2025 (under SECURE 2.0) represents the most significant structural change to 401(k) limits in over two decades.
401(k) Contribution Limits 2026: IRS Official Numbers
The IRS officially announced 2026 limits on November 13, 2025, via IRS Notice 2025-67 (IR-2025-111). Here is the complete 401k 2026 contribution limit breakdown. The max 401k contribution 2026 for employee deferrals rises to $24,500 — a $1,000 increase from 2025. The headline: the 401(k) limits 2026 represent a meaningful increase across every age group, and the 401(k) 2026 contribution limit IRS max for the combined ceiling rises to $72,000. If you are planning your 401(k) contribution 2026 elections, use the table below as your reference.

| Combined with super catch-up (60–63) | $81,250 | $83,250 | +$2,000 |
| IRA contribution limit (under 50) | $7,000 | $7,500 | +$500 |
⚠️ New 2026 Rule for High Earners: Roth Catch-Up Mandate
Starting January 1, 2026, the IRS implements a SECURE 2.0 mandate affecting catch-up contributions for high earners: if you earned more than $150,000 in FICA wages in 2025, your 2026 catch-up contributions must be made as Roth (after-tax) contributions, regardless of whether you typically use a traditional (pre-tax) 401(k).
This rule applies to ages 50+ and 60–63 catch-ups alike. It doesn’t change how much you can contribute — only which tax treatment applies to the catch-up portion.
Action item: If your 2025 W-2 wages exceeded $150,000, confirm with your plan administrator before January 2026 that your catch-up elections are designated as Roth.
