The IRS updates retirement contribution limits every year for inflation. In 2026, you can defer significantly more into your 401(k) than most people realize-especially if you're over 50 or have access to employer match and mega backdoor Roth conversions. Here's what changed from 2025 and how to maximize your retirement savings.
2026 Contribution Limits at a Glance
| Account Type | 2026 Limit | Age 50+ Catch-Up |
|---|---|---|
| 401(k) Employee Deferral | $24,500 | +$8,000 = $32,500 |
| 401(k) Super Catch-Up (age 60-63) | - | $11,250 in place of the standard catch-up = $35,750 |
| 401(k) Total (employee + employer) | $72,000 | N/A |
| Traditional or Roth IRA | $7,500 | +$1,100 = $8,600 |
| SEP IRA (self-employed) | 25% of net income (max $72,000) | N/A |

How the Limits Work Together
Employee Deferral: $24,500 (or $32,500 at 50+)
This is your personal contribution-money taken directly from your paycheck. You decide how much to defer (up to the limit). If you earn $80,000/year, you could defer up to $24,500, leaving $55,500 as take-home pay (before other deductions and taxes).
Employer Contributions (Match & Profit-Sharing)
Your employer can also contribute via matching or profit-sharing. A common match is 3-5%. If you earn $100,000 and your employer matches 4%, they contribute $4,000. This counts toward the $72,000 total limit, not in addition to it.
The $72,000 Total Limit
Your contributions and your employer's contributions combined cannot exceed $72,000 for 2026. Examples:
- Scenario A: You defer $24,500 + employer match $5,000 = $29,500 total. You're well under the limit.
- Scenario B: You defer $24,500 + employer match $15,000 + employer profit-sharing $32,500 = $72,000. You've maxed it out.
- Scenario C: You defer $50,000 (if allowed) + employer match $25,000 = $75,000. You've exceeded the limit, so the employer must reduce their contribution.
Catch-Up Contributions for Ages 50+
Standard Catch-Up: Age 50+
If you're 50 or older, you can defer an extra $8,000 in 2026, for a total of $32,500. This applies once you reach 50 and lasts for the rest of your working life. Many employers automatically increase payroll deductions when you turn 50 if you opt in.
Super Catch-Up: Ages 60-63
Starting in 2025, SECURE 2.0 gives workers ages 60-63 a higher catch-up limit of $11,250 that applies in place of the standard $8,000 catch-up, for a total of $35,750 in 2026. This is a four-year window as you approach retirement. Once you turn 64, you fall back to the standard $32,500 total. This provision is valuable for late-career savers trying to catch up on retirement savings.
Super Catch-Up Example
You're 61 years old in 2026. You can defer:
$24,500 (standard) + $11,250 (the 60-63 catch-up, which replaces the $8,000 standard catch-up) = $35,750
This is a significant boost if your plan allows it.
Mega Backdoor Roth: After-Tax 401(k) Contributions
Some 401(k) plans allow "after-tax" contributions beyond the employee deferral limit. This is not a Roth contribution yet, but it can be converted to a Roth IRA.
How it works: You've deferred $24,500 in 2026. Your plan has a $72,000 total limit. That leaves $47,500 available for after-tax contributions (before subtracting any employer match). You contribute the remainder in after-tax dollars (not pre-tax, no tax deduction). Then you immediately convert it to a Roth IRA. The conversion is tax-free because you've already paid tax on the contribution.
Why do this? You're saving up to an extra $47,500 in a Roth account, with all future growth tax-free. This is only available if your employer plan offers after-tax contributions and in-service conversions. Check with your plan administrator.
IRA Contribution Limits
If you don't have access to a 401(k) or want additional retirement savings, an IRA is the next tier:
| Account Type | 2026 Limit | Age 50+ |
|---|---|---|
| Traditional IRA | $7,500 | $8,600 |
| Roth IRA | $7,500 | $8,600 |
| SEP IRA (self-employed) | 25% of net, max $72,000 | Same |
Note: You can contribute to both a 401(k) and an IRA in the same year. The limits are separate. If you max your 401(k) at $24,500, you can still contribute $7,500 to an IRA. However, deductibility of Traditional IRA contributions phases out if you have a 401(k) at work.
Health Savings Accounts (HSAs)
HSAs are triple-tax-advantaged retirement accounts, though they're officially for healthcare expenses. If you have a high-deductible health plan (HDHP), you can contribute:
- Self-only coverage: $4,400 in 2026
- Family coverage: $8,750 in 2026
- Age 55+ catch-up: Additional $1,000
HSA contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. If you're young and healthy, you can save the contributions for retirement (after age 65, non-medical withdrawals are taxed like a Traditional IRA, but without the 20% penalty).

Frequently Asked Questions
What happens if I exceed the contribution limit?
If you accidentally over-contribute, your plan administrator should catch it and remove the excess. The excess is subject to a 6% excise tax per year it remains in the account. To avoid this, monitor your contributions, especially if you have multiple employers. Self-employed individuals should track their own contributions closely.
Can I contribute to a 401(k) and an IRA in the same year?
Yes. Your 401(k) contributions are separate from IRA contributions. However, if you contribute to a 401(k) at work, your ability to deduct Traditional IRA contributions may be limited based on income. For Roth IRAs, high income can prevent contributions entirely. Consult a tax professional if you're in this situation.
Do I have to contribute to my 401(k)?
No. 401(k) contributions are voluntary (unless your plan is auto-enrollment). However, missing out on employer match is leaving free money on the table. Most financial advisors recommend contributing at least enough to get the full match.
Are these limits pre-tax or post-tax?
The $24,500 employee deferral limit applies to pre-tax contributions (Traditional 401k) or Roth contributions (Roth 401k). Both count toward the limit. Employer match and profit-sharing are always on top. Mega backdoor Roth uses after-tax money and counts toward the $72,000 total.
