The SECURE 2.0 Act of 2022 introduced a higher catch-up limit specifically for workers aged 60, 61, 62, or 63. Instead of $8,000, they can contribute $11,250 extra in 2026 — for a total of $35,750. At age 64 this drops back to the standard $8,000 catch-up. Plan your contributions carefully around this window if you're approaching this age range.
How Employer Matching Works With the Limits
Employer contributions — matching or profit-sharing — count toward the §415 total limit ($72,000) but not the employee elective deferral limit ($24,500). This means your employer's match never reduces how much you personally can contribute.
| Scenario | Your Contribution | Employer Match | Total | §415 Remaining |
|---|---|---|---|---|
| Max employee only (under 50) | $24,500 | $0 | $24,500 | $47,500 for employer |
| Employee + 4% match on $100K salary | $24,500 | $4,000 | $28,500 | $43,500 |
| Employee + 6% match on $150K salary | $24,500 | $9,000 | $33,500 | $38,500 |
| Max employee + max employer match | $24,500 | $47,500 | $72,000 | $0 |
If your employer matches 100% of contributions up to 4% of salary, and you earn $80,000, that's a free $3,200 per year. Not contributing enough to capture the full match is leaving guaranteed 100% return on the table. This should be your first financial priority — before paying off low-interest debt, before investing in a taxable account.
Traditional 401k vs Roth 401k — Which to Choose in 2026?
Most employers now offer both a traditional and Roth 401k option. The contribution limits are identical — $24,500 total across both. The difference is when you pay tax.
| Traditional 401k | Roth 401k | |
|---|---|---|
| Tax on contribution | Pre-tax — reduces taxable income now | After-tax — no deduction |
| Tax on withdrawals | Taxed as ordinary income | Tax-free (if rules met) |
| 2026 income limit | None | None (unlike Roth IRA) |
| Required Minimum Distributions | Yes, starting age 73 | No RMDs (from 2024 onwards) |
| Best for | High earners expecting lower tax bracket in retirement | Younger workers, those expecting higher future rates |
Many financial planners recommend splitting contributions between traditional and Roth — e.g., $12,000 traditional + $11,500 Roth — to diversify your tax exposure in retirement. You won't know what tax rates will be in 20–30 years, so having both pre-tax and after-tax buckets gives you flexibility to manage your tax bill in any environment.
Solo 401k Limits 2026 (Self-Employed)
If you're self-employed — freelancer, sole proprietor, or single-member LLC — a Solo 401k lets you contribute as both employer and employee, significantly increasing what you can shelter.
Solo 401k Example — $120,000 Net Self-Employment Income
Employer contribution (25% × $120,000): $30,000
Total Solo 401k contribution: $54,500
§415 limit: $72,000 — still $17,500 under the cap
| Net Self-Emp Income | Employee | Employer (25%) | Total |
|---|---|---|---|
| $60,000 | $24,500 | $15,000 | $39,500 |
| $100,000 | $24,500 | $25,000 | $49,500 |
| $150,000 | $24,500 | $37,500 | $62,000 |
| $190,000+ | $24,500 | $47,500 | $72,000 (max) |
What Happens If You Over-Contribute?
Exceeding the $24,500 elective deferral limit — most commonly when changing jobs and contributing to two plans in the same year — has serious tax consequences:
- The excess must be withdrawn by April 15 of the following year (with earnings)
- If not corrected in time, the excess is taxed twice — once in the year contributed, and again when eventually withdrawn
- Contact your plan administrator immediately if you suspect an over-contribution
- The §415 total limit ($72,000) can only be exceeded by the plan itself correcting it — excess employer contributions are returned
If you change jobs mid-year, both plan administrators are unaware of each other's contributions. You could inadvertently contribute $24,500 to Plan A and another $10,000 to Plan B — a $10,000 excess. Track your year-to-date contributions carefully when switching employers. The IRS does not automatically flag this for you.
How Much Should You Actually Contribute?
The answer depends on your situation, but a practical priority order:
- Contribute enough to get 100% of the employer match — this is a guaranteed 50–100% immediate return
- Max your HSA if eligible ($4,300 single / $8,550 family in 2026) — triple tax advantage beats even a Roth IRA
- Max your IRA ($7,500 Roth or Traditional in 2026)
- Max your 401k — contribute the full $24,500 if cash flow allows
- Taxable brokerage account — once all tax-advantaged space is used
