401(k) Contribution Limits 2026: What Changed and What Didn't

Every January, the IRS adjusts retirement account limits for inflation. For 2026, the numbers shifted — the base deferral limit increased by $1,000, catch-up contributions went up as well, and a brand-new super catch-up provision for workers aged 60–63 continues to change the game for those in the final sprint to retirement.

If you contribute to a 401(k), 403(b), or similar employer-sponsored plan, here's everything you need to know about the 2026 limits — and how to make the most of them.

The 2026 limits at a glance

Let's start with the numbers. The table below covers all the key limits for employer-sponsored retirement plans in 2026.

The base deferral limit increased by $1,000 — from $23,500 to $24,500. The 50+ catch-up increased by $500, from $7,500 to $8,000. IRA limits also rose by $500.

The super catch-up for ages 60–63 holds at $11,250, unchanged from its 2025 introduction.

The super catch-up: a game-changer for ages 60–63

The SECURE 2.0 Act, signed into law in December 2022, included a provision that took effect in 2025: workers aged 60 through 63 can make an enhanced catch-up contribution of $11,250 — up from the standard $8,000 catch-up available to those 50 and older.

This means a 61-year-old worker can defer up to $35,750 in 2026: the $24,500 standard limit plus the $11,250 super catch-up. Including employer contributions, the total could reach $83,250 — an extraordinary amount of tax-advantaged savings in a single year.

Why does this matter? Because the years between 60 and 63 are often peak earning years. The kids are out of the house. The mortgage might be paid off. Expenses are lower. And retirement is close enough that every dollar saved has an immediate, tangible impact on your retirement income.

Consider Margaret, 61, a senior project manager earning $145,000. Her employer matches 4% of salary — about $5,800 per year. If Margaret maxes out her super catch-up in 2026, her total 401(k) contribution is:

• Employee deferral: $24,500
• Super catch-up: $11,250
• Employer match: $5,800
• Total: $41,550

That's $41,550 sheltered from taxes in a single year. If Margaret does this for the four years she's eligible (ages 60–63), she adds over $143,000 in employee contributions to her retirement accounts — potentially $175,000 or more including investment growth. You can model scenarios like Margaret's with our 401(k) calculator to see how contributions, employer match, and growth compound over time.

There's one important nuance: under SECURE 2.0, high earners (those who earned more than $150,000 from their employer in the prior year) must make catch-up contributions on a Roth basis starting in 2026. If you earned over $150,000 in 2025, your catch-up contributions — whether the standard $8,000 or the super $11,250 — must go into a Roth 401(k), not a Traditional 401(k). The standard $24,500 deferral can still be pre-tax or Roth — your choice.

Traditional vs. Roth 401(k): the 2026 decision

Every dollar you contribute to a 401(k) is either Traditional (pre-tax) or Roth (after-tax). The choice has meaningful long-term implications, and the new Roth catch-up requirement makes it more relevant than ever.

Traditional 401(k) contributions reduce your taxable income today. If you're in the 24% bracket and contribute $24,500, you save roughly $5,880 in federal taxes this year. The money grows tax-deferred, and you pay income tax when you withdraw in retirement.

Roth 401(k) contributions don't reduce your current taxes. You pay full tax on the $24,500 now. But the money grows tax-free, and qualified withdrawals in retirement are completely tax-free — no income tax, no impact on Social Security taxation, no Medicare IRMAA surcharges.

The general rule of thumb: if you expect to be in a lower tax bracket in retirement, Traditional makes more sense — you defer taxes from a high-rate year to a low-rate year. If you expect the same or higher bracket in retirement — perhaps because of large RMDs, or because you believe tax rates will rise — Roth is the better bet.

For many workers in their 50s and 60s, a split approach works well. Make your base deferral in Traditional to get the current tax break, and direct catch-up contributions to Roth for tax-free income later. This creates a diversified tax portfolio: some retirement income will be taxable (Traditional), some will be tax-free (Roth), giving you flexibility to manage your bracket year by year.

The employer match: free money with strings

Your employer's matching contribution doesn't count toward the $24,500 employee limit. It counts toward the overall $72,000 annual limit (or $80,000/$83,250 with catch-up). Most employers match 3–6% of salary, though formulas vary widely.

Common match structures include:

• Dollar-for-dollar up to 3% — you contribute 3% of salary, employer adds 3%
• 50 cents on the dollar up to 6% — you contribute 6%, employer adds 3%
• Tiered match — 100% on first 3%, then 50% on next 2%

The critical rule: if you're not contributing enough to capture the full employer match, you're leaving free money on the table. Before optimizing anything else — Roth conversions, backdoor strategies, tax-loss harvesting — make sure you're getting every dollar of employer match available to you.

One important change: under SECURE 2.0, employer matching contributions can now be designated as Roth. Previously, all employer matches went into the Traditional side of your 401(k) regardless of your election. Starting in 2023, employers can offer Roth matching — though you'll owe income tax on the match in the year it's contributed. Not all plans have adopted this option yet. Check with your HR department.

Strategies to maximize your 2026 contributions

Front-load vs. spread evenly. Some savers prefer to max out contributions early in the year — contributing heavily from January through June and then dropping to a lower rate. The advantage: your money is invested sooner, which historically produces slightly better returns. The risk: if your employer match is calculated per-paycheck rather than annually, you might miss matching contributions in the months after you've maxed out. Many — but not all — plans have a "true-up" provision that corrects for this at year-end. Verify with your plan administrator before front-loading.

Coordinate with your spouse. If both you and your spouse have access to employer plans, maximize both. Two workers under 50 can defer $49,000 combined. Two workers aged 60–63 can defer $71,500 combined — nearly $72,000 sheltered from taxes in a single year. Add employer matches, and total contributions could well exceed $100,000.

Don't forget the IRA. Your 401(k) contribution doesn't prevent you from also contributing to an IRA. In 2026, you can contribute $7,500 to a Traditional or Roth IRA ($8,500 if 50+), subject to income limits for Roth and deductibility limits for Traditional. If your income exceeds the Roth IRA phase-out thresholds, consider a backdoor Roth IRA.

Consider the mega backdoor Roth. If your plan allows after-tax (non-Roth) contributions and in-service distributions or in-plan Roth conversions, you can contribute up to the $72,000 total limit and convert the after-tax portion to Roth. This mega backdoor strategy lets you get far more money into Roth accounts than the standard contribution limits allow. Not all plans support this — it requires specific plan features.

Other 2026 limit updates

IRA limits. The IRA contribution limit increased to $7,500 in 2026 ($8,500 for those 50+). The $1,000 catch-up for IRA remains flat — it hasn't been indexed to inflation yet despite SECURE 2.0's intent.

Roth IRA income limits. Direct Roth IRA contributions phase out above certain MAGI thresholds (check IRS.gov for the exact 2026 figures). If your income exceeds those thresholds, the backdoor Roth IRA remains available regardless of income.

No RMDs from Roth 401(k). Starting in 2024, Roth 401(k) accounts are no longer subject to Required Minimum Distributions during the owner's lifetime. This makes Roth 401(k) contributions significantly more attractive for high earners who want tax-free growth without the RMD pressure — a key advantage over Traditional 401(k) balances that will eventually force taxable distributions.

The bottom line

The 2026 contribution limits reflect meaningful increases — $1,000 more in the base deferral, $500 more in the standard catch-up, and an extra $500 in IRA room. The super catch-up provision for workers aged 60–63 remains at $11,250, unchanged from its 2025 introduction.

If you're in that 60–63 window, you have a four-year opportunity to turbocharge your retirement savings in a way that wasn't possible before SECURE 2.0. Don't let it pass.

For everyone else, the fundamentals haven't changed: contribute enough to capture your full employer match. Increase contributions when you get raises. Consider the Traditional vs. Roth decision based on your current and expected future tax brackets. And if you can max out the $24,500 limit, do it — your 70-year-old self will thank you.
