## How the SEP IRA contribution limit is calculated

The IRS contribution limit for self-employed individuals is technically 25% of net earnings from self-employment, but the actual calculation involves an adjustment for the self-employment tax deduction.

**Formula:**
```
1. SE Tax = Net SE Income x 0.9235 x 15.3%
2. SE Tax Deduction = SE Tax / 2
3. Net Earnings for SEP = Net SE Income - SE Tax Deduction
4. Max SEP Contribution = min(Net Earnings x 25%, IRS Dollar Limit)
```

The result is effectively about 18.59% of net self-employment income (before the SE tax deduction). The IRS dollar limits are:
- **2025:** $70,000
- **2024:** $69,000
- **2023:** $66,000
- **2022:** $61,000

## Tax advantages of a SEP IRA

SEP IRA contributions are fully tax-deductible in the year they are made (up to the IRS limit). This reduces your adjusted gross income, which can lower your overall tax bill substantially for high earners.

For example, a self-employed person earning $200,000 with a 32% marginal tax rate could contribute up to approximately $37,180 to a SEP IRA, saving around $11,900 in federal income taxes in that year alone. The investments then grow tax-deferred until retirement.

Unlike a Roth IRA, SEP IRA contributions reduce current-year taxes, making them especially valuable for high-income self-employed individuals who expect to be in a lower tax bracket in retirement.

## SEP IRA vs. Solo 401(k)

Both are popular retirement accounts for self-employed individuals, but they work differently:

- **SEP IRA:** Employer-only contributions (no employee contribution). Simple to set up. Contributions are flexible year to year. No catch-up contributions for those 50+.
- **Solo 401(k):** Has both employee and employer contribution components. Allows higher contributions at lower income levels. Catch-up contributions allowed for those 50+. More complex to administer.

For high earners (above roughly $150,000), the maximum contribution amounts are often similar. At lower income levels, the Solo 401(k) often allows larger total contributions because of the employee deferral component.

## FAQs

**Q:** Can I contribute to a SEP IRA if I also have a W-2 job?


**A:** Yes. Having W-2 income does not prevent you from contributing to a SEP IRA based on your self-employment income. However, the combined contributions across all employer plans for one employer cannot exceed the IRS annual dollar limit.


**Q:** Is the SEP IRA contribution limit really 25%?


**A:** The stated limit is 25% of net earnings from self-employment, but net earnings are calculated after subtracting the deductible half of self-employment tax. This adjustment means the effective contribution rate is approximately 18.59% of gross self-employment income.


**Q:** What is the deadline to contribute to a SEP IRA?


**A:** You can make SEP IRA contributions for a tax year up to the due date of your tax return, including extensions. This can be as late as October 15 of the following year.


**Q:** Do SEP IRA contributions affect Social Security or Medicare taxes?


**A:** No. SEP IRA contributions reduce federal (and usually state) income taxes but do not reduce self-employment taxes.


**Q:** Can employees contribute to a SEP IRA?


**A:** No. Only the employer makes contributions to a SEP IRA. All contributions come from the business owner. If you have employees, you generally must contribute the same percentage of compensation for eligible employees as you do for yourself.
