SECURE 2.0 Act Changes
New for 2026: High earners (those earning $145,000+ in the prior year) must make catch-up contributions as Roth only. This applies to both the standard catch-up ($8,000) and the new super catch-up ($11,250) for ages 60-63.
The SECURE 2.0 Act of 2022 introduced several changes phasing in over multiple years. The super catch-up contribution for ages 60-63 took effect in 2025, allowing workers in their peak earning years to accelerate savings before retirement. Starting in 2026, the mandatory Roth catch-up rule applies to employees who earned over $145,000 from the same employer in the prior year - these workers must direct all catch-up contributions to a designated Roth account. Employers that do not offer a Roth 401(k) option must add one to keep catch-up contributions available.
How Limits Are Adjusted Each Year
The IRS adjusts 401(k) contribution limits annually based on cost-of-living increases tied to the Consumer Price Index (CPI-U). Adjustments are rounded to the nearest $500. In years with low inflation, limits may stay flat. The IRS publishes COLA adjustments each October for the following calendar year.
Strategies to Maximize Your Contributions
- Front-load contributions early in the year. Contributing 50-75% of pay in January through March means your money is invested longer. Check if your plan has a true-up provision so you don't lose employer match.
- Use auto-escalation. Set your plan to automatically increase your contribution rate by 1% each year. Most workers don't notice the difference in take-home pay.
- Combine Traditional and Roth. The $24,500 limit applies to the combined total. Splitting lets you diversify your tax exposure in retirement.
- Don't forget after-tax contributions. Some plans allow after-tax (non-Roth) contributions up to the $72,000 415(c) limit. Combined with an in-plan Roth conversion, this is the mega backdoor Roth strategy.
- Coordinate with IRA contributions. You can contribute to both a 401(k) ($24,500) and IRA ($7,000) in the same year. The IRA deduction may phase out if covered by a workplace plan.
Employer Contribution Limits
Employer contributions (match + profit-sharing) are separate from your employee deferral limit. The combined employee + employer total cannot exceed the lesser of $72,000 or 100% of compensation. Employer contributions are always pre-tax regardless of whether your deferrals are Roth. The compensation cap ($350,000) limits the salary used to calculate employer contributions.
| Salary | Max Employee | Max Employer (6% match) | Max Total |
|---|---|---|---|
| $60,000 | $24,500 | $3,600 | $28,100 |
| $100,000 | $24,500 | $6,000 | $30,500 |
| $150,000 | $24,500 | $9,000 | $33,500 |
| $200,000 | $24,500 | $12,000 | $36,500 |
| $350,000+ | $24,500 | $21,000 (capped) | $45,500 |
What Happens If You Over-Contribute
If your total employee deferrals across all 401(k) plans exceed the annual limit, you must withdraw the excess by April 15 of the following year. Excess deferrals left in the plan are taxed twice - once in the year contributed and again when withdrawn. Contact your plan administrator as soon as you notice an over-contribution. Workers with multiple jobs are especially at risk since each employer tracks only their own plan.
Paycheck Impact by Contribution Rate
Understanding how 401(k) contributions affect your take-home pay helps you plan your budget. Traditional 401(k) contributions reduce your taxable income, so the actual cost is less than the contribution amount. Here is the approximate paycheck impact for different salary levels contributing enough to max out in 2026:
| Salary | Rate to Max Out | Monthly 401(k) | Monthly Tax Savings (24%) | Net Paycheck Reduction |
|---|---|---|---|---|
| $60,000 | 40.8% | $2,042 | $490 | $1,552 |
| $80,000 | 30.6% | $2,042 | $490 | $1,552 |
| $100,000 | 24.5% | $2,042 | $490 | $1,552 |
| $150,000 | 16.3% | $2,042 | $490 | $1,552 |
| $200,000 | 12.3% | $2,042 | $654 (32%) | $1,388 |
Tax savings assume single filer with standard deduction. Actual savings depend on your marginal bracket and state taxes. Roth contributions do not reduce taxable income.
Catch-Up Contribution Strategy by Age
Workers over 50 can contribute beyond the standard limit. The SECURE 2.0 Act created a new super catch-up tier for ages 60-63. Here is the maximum you can defer at each age:
| Age Range | Standard Deferral | Catch-Up | Total Maximum | Strategy |
|---|---|---|---|---|
| Under 50 | $24,500 | $0 | $24,500 | Focus on reaching 15% savings rate including match |
| 50-59 | $24,500 | $8,000 | $32,500 | Use catch-up to accelerate savings in peak earning years |
| 60-63 | $24,500 | $11,250 | $35,750 | 4-year window for maximum contributions before retirement |
| 64+ | $24,500 | $8,000 | $32,500 | Reverts to standard catch-up after the 60-63 window |
The 60-63 super catch-up window is especially valuable. A worker who contributes $35,750 per year for four years (ages 60-63) defers $143,000 in those years alone. At 7% annual returns, that grows to approximately $195,000 by age 67.
401(k) vs Other Retirement Plan Limits
Different retirement plans have different contribution ceilings. If you have access to multiple plan types, coordinating across them can significantly increase your total tax-advantaged savings:
| Plan Type | 2026 Employee Limit | Catch-Up (50+) | Employer/Total Limit |
|---|---|---|---|
| 401(k) | $24,500 | $8,000 / $11,250 | $72,000 |
| 403(b) | $24,500 | $8,000 + $3,000 (15-yr rule) | $72,000 |
| 457(b) | $24,500 | $8,000 (separate limit) | $24,500 (no employer) |
| SIMPLE 401(k)/IRA | $16,500 | $3,500 / $5,250 (60-63) | $16,500 + match |
| Traditional/Roth IRA | $7,000 | $1,000 | $7,000 |
| SEP IRA | N/A (employer only) | None | 25% of comp, up to $72,000 |
| Solo 401(k) | $24,500 | $8,000 | $72,000 |
Key coordination rule: 401(k) and 403(b) limits are shared - you cannot contribute $24,500 to each. However, 457(b) limits are completely separate. A government employee with both a 403(b) and a 457(b) can defer up to $49,000 combined ($24,500 + $24,500) in 2026, not counting catch-up contributions.
How Much Will Your 401(k) Be Worth?
The power of 401(k) contributions compounds over decades. Here is what consistent annual contributions at 7% average returns grow to over different time horizons:
| Annual Contribution | 10 Years | 20 Years | 30 Years | 40 Years |
|---|---|---|---|---|
| $12,000 (10% of $120K) | $173,085 | $525,680 | $1,133,530 | $2,395,923 |
| $24,500 (max under 50) | $353,300 | $1,073,400 | $2,314,100 | $4,890,900 |
| $32,500 (max 50+) | $469,200 | $1,425,600 | $3,073,800 | N/A |

Nondiscrimination Testing and HCE Limits
Highly Compensated Employees (HCEs) - those earning over $160,000 in 2026 - may face additional contribution restrictions. The IRS requires 401(k) plans to pass nondiscrimination tests ensuring that HCEs do not benefit disproportionately compared to non-HCEs. If a plan fails testing, HCE contributions may be refunded or limited to as low as 2% of salary.
Safe Harbor 401(k) plans avoid this problem by committing to a minimum employer contribution (typically 3-4% of salary for all employees or a match formula). Most large employers use Safe Harbor plans specifically so all employees, including executives, can contribute the full $24,500.
Frequently Asked Questions
No. The $24,500 limit only applies to your employee elective deferrals. Employer contributions are separate and count toward the $72,000 total annual additions limit (IRS Section 415c).
The SECURE 2.0 Act created an enhanced catch-up for workers aged 60-63. Instead of the standard $8,000 catch-up, these workers can contribute an additional $11,250 (total $35,750) in 2026. This provision sunsets - workers who turn 64 revert to the standard catch-up amount.
Yes. You can contribute up to $24,500 to a 401(k) and up to $7,000 to an IRA in 2026. However, the IRA tax deduction may be reduced or eliminated if you are covered by a workplace plan and earn above certain income thresholds (IRS deduction limits).
The employee deferral limit increased from $23,500 (2025) to $24,500 (2026). Catch-up went from $7,500 to $8,000. The total annual additions limit rose from $70,000 to $72,000. The compensation cap increased from $345,000 to $350,000.
Per person, across all employers. If you work two jobs, your total employee deferrals across both 401(k) plans cannot exceed $24,500. However, each employer can make separate employer contributions up to their own 415(c) limit.
