SEP IRA
SEP IRA
Quick Definition
A SEP IRA (Simplified Employee Pension Individual Retirement Account) is a retirement savings plan that allows self-employed individuals, freelancers, and small business owners to contribute significantly more than a standard IRA -- up to 25% of net self-employment income or $70,000 in 2025, whichever is less.
What It Means
The SEP IRA was designed to give small business owners and the self-employed a simple, high-contribution retirement savings option. The word "simplified" is accurate: there are no annual filing requirements with the IRS, no complex non-discrimination testing, and setup is straightforward at any major brokerage.
If you are a freelancer, consultant, sole proprietor, LLC owner, or run a small business, the SEP IRA is one of the most powerful tax tools available to you. A high-earning self-employed person can shelter tens of thousands of dollars from income tax each year.
How It Works
Contribution Limits (2025)
| Contributor Type | Contribution Rule | Maximum |
|---|---|---|
| Self-employed (sole proprietor) | 20% of net self-employment income* | $70,000 |
| S-Corp owner (W-2) | 25% of W-2 compensation | $70,000 |
| Employee of a small business | 25% of W-2 compensation | $70,000 |
*The 20% for sole proprietors (vs. 25% for employees) accounts for the self-employment tax deduction. The effective rate is 20% of net profit after deducting half of self-employment taxes.
Self-Employed Contribution Calculation
If you are a sole proprietor with $120,000 in net self-employment income:
- Calculate self-employment tax: $120,000 × 15.3% = $18,360 (but only half is deductible = $9,180)
- Adjusted net income: $120,000 - $9,180 = $110,820
- SEP IRA contribution: $110,820 × 20% = $22,164
| Net Self-Employment Income | Maximum SEP IRA Contribution |
|---|---|
| $50,000 | ~$9,293 |
| $100,000 | ~$18,587 |
| $150,000 | ~$27,880 |
| $200,000 | ~$37,174 |
| $280,000+ | $70,000 (maximum) |
Contribution Deadline
Unlike a 401(k) or standard IRA, SEP IRA contributions can be made up to the tax filing deadline including extensions. For sole proprietors filing a Schedule C, this means you can contribute as late as October 15 (with extension) for the prior tax year. This gives you flexibility to calculate your final profit and optimize contributions based on actual tax liability.
SEP IRA vs. Solo 401(k) vs. Traditional IRA
| Feature | SEP IRA | Solo 401(k) | Traditional IRA |
|---|---|---|---|
| 2025 max contribution | $70,000 | $70,000 ($77,500 with catch-up) | $7,000 ($8,000 if 50+) |
| Roth option? | No | Yes (Roth Solo 401k) | Traditional only (Roth is separate) |
| Loans allowed? | No | Yes | No |
| Employee plans required? | Yes (if you have employees) | No (self + spouse only) | N/A |
| Complexity | Very simple | Moderate | Very simple |
| Self-employed contribution rate | ~20% of net income | ~20% + up to $23,500 as employee | Unrelated to income % |
| Best for | Simple, high income | Income under ~$150k seeking maximum contribution | Supplemental savings |
The Solo 401(k) can actually allow higher contributions than a SEP IRA for self-employed people earning under roughly $140,000 per year, because it allows both an employee deferral ($23,500) and an employer contribution (25%). For higher earners, the SEP IRA and Solo 401(k) converge at the $70,000 cap.
Employing Others: The Catch
If you have employees other than yourself (and possibly a spouse), a SEP IRA requires you to contribute the same percentage of compensation for all eligible employees that you contribute for yourself. If you contribute 20% for yourself, you must contribute 20% for every eligible employee.
Eligible employees are those who:
- Are at least 21 years old
- Have worked for you in at least 3 of the last 5 years
- Have received at least $750 in compensation from you
This can make SEP IRAs expensive for employers with staff. Business owners with multiple full-time employees often switch to a SIMPLE IRA or 401(k) plan instead.
Tax Savings Example
Scenario: David is a freelance software engineer with $180,000 in net self-employment income. He is in the 32% federal tax bracket plus 6% state tax (38% combined marginal rate).
| Retirement Plan | Max Contribution | Tax Savings (38% rate) |
|---|---|---|
| No retirement plan | $0 | $0 |
| Traditional IRA only | $7,000 | $2,660 |
| SEP IRA | $33,450 | $12,711 |
| SEP IRA + Traditional IRA | $40,450 | $15,371 |
David saves over $15,000 in taxes per year compared to not using these accounts. That money remains invested rather than going to the IRS.
Investment Options
Like a standard IRA, a SEP IRA can hold:
- Individual stocks
- ETFs (including low-cost index ETFs)
- Mutual funds
- Bonds
- Certificates of deposit
- REITs
Open a SEP IRA at any major brokerage: Fidelity, Vanguard, Schwab, or TD Ameritrade. Vanguard and Fidelity offer the lowest-cost index funds.
Key Points to Remember
- Contribute up to 25% of compensation or $70,000 (20% of net self-employment income for sole proprietors)
- Contributions are 100% tax-deductible and reduce self-employment taxable income
- No Roth option -- SEP IRAs are always pre-tax (consider a Roth IRA alongside for after-tax savings)
- Contribution deadline extends to tax filing deadline including extensions (October 15 for most)
- Employees must receive the same contribution percentage as the owner
- SEP IRA assets are immediately 100% vested -- employees own contributions from day one
Common Mistakes to Avoid
- Not contributing for eligible employees: If you have staff, you are legally required to contribute the same percentage for them. Missing this can result in plan disqualification.
- Confusing net vs. gross income: The contribution calculation is based on net self-employment income after deducting half of self-employment taxes.
- Choosing SEP IRA when Solo 401(k) is better: For lower-earning self-employed individuals, the Solo 401(k) allows higher contributions. Run the math for your specific income level.
- Missing the extended deadline: Many self-employed people do not realize they can contribute after December 31 up to the filing extension date.
Frequently Asked Questions
Q: Can I have both a SEP IRA and a Roth IRA? A: Yes. You can contribute to a SEP IRA for the employer (self-employed) portion of your retirement savings and separately contribute up to $7,000 to a Roth IRA if your income is within the Roth limits.
Q: What if my self-employment income varies year to year? A: The SEP IRA is ideal for variable income because you are not committed to a fixed contribution. In a great year, contribute more. In a lean year, contribute less or nothing. There is no required minimum annual contribution.
Q: Can I roll a SEP IRA into a 401(k) if I get a job? A: Yes. SEP IRA balances can be rolled into a 401(k), 403(b), or other eligible employer plan, or kept in the SEP IRA or rolled to a traditional IRA at any time without taxes.
Q: Do SEP IRA contributions count toward the standard IRA limit? A: No. SEP IRA contributions are separate from the $7,000 traditional/Roth IRA limit. You can contribute to both a SEP IRA and a separate Roth IRA in the same year.
