What Is a SEP IRA?
A SEP IRA (Simplified Employee Pension Individual Retirement Account) is a tax-deferred retirement account designed specifically for self-employed individuals and small business owners. It works like a Traditional IRA — contributions are pre-tax and tax-deductible, growth is tax-deferred, and withdrawals in retirement are taxed as ordinary income.
The key difference from a Roth or Traditional IRA: the contribution limit is dramatically higher. While a Roth IRA caps at $7,000/year, a SEP IRA allows contributions of up to $69,000/year — making it the single most powerful tax-advantaged retirement vehicle for high-income self-employed individuals.
$69,000 Max Contribution
Nearly 10x the Roth IRA limit. A self-employed person earning $200,000+ can shelter up to $42,525 per year in pre-tax contributions.
100% Tax Deductible
SEP IRA contributions are fully deductible as a business expense on Schedule 1. A $25,000 contribution in the 24% bracket saves $6,000 in federal taxes.
April 15 Deadline (With Extension)
Unlike Solo 401(k) deferrals (Dec 31 deadline), SEP IRA contributions can be made until your tax filing deadline — October 15 with an extension.
Who Can Open a SEP IRA?
Sole Proprietors & Freelancers
Any self-employed individual with Schedule C income. Contribute up to 20% of net self-employment income (after SE tax deduction), capped at $69,000.
S-Corporation Owner-Employees
S-corp owners who pay themselves a W-2 salary can contribute 25% of their W-2 compensation from the S-corp into a SEP IRA, up to $69,000.
Employers with Employees
If you have employees who worked 3 of the last 5 years, are 21+, and earned $750+, you must contribute the same percentage of compensation to their SEP IRAs as you contribute to your own.
Side Hustle + W-2 Job
You can have a SEP IRA based on self-employment income even if you also have a W-2 job with a 401(k). The 401(k) employee limit is separate from the SEP IRA employer contribution limit.
The Real Dollar Math: SEP IRA vs Roth IRA
The contribution gap between a SEP IRA and a Roth IRA is enormous for high-income self-employed investors. Below are the realistic SEP IRA maximums by income level for a sole proprietor in 2026, compared to the Roth IRA cap. Note: The SEP IRA formula for sole proprietors is approximately 18.587% of gross self-employment income — your CPA can calculate your exact maximum.
| Gross SE Income | Max SEP Contribution | Max Roth IRA | SEP Advantage | Tax Savings (24%) |
|---|---|---|---|---|
| $50,000 | $10,706 | $7,000 | +$3,706 | $2,677 |
| $75,000 | $15,947 | $7,000 | +$8,947 | $3,987 |
| $100,000 | $21,263 | $7,000 | +$14,263 | $5,316 |
| $150,000 | $31,894 | $7,000 | +$24,894 | $7,974 |
| $200,000 | $42,525 | $7,000 | +$35,525 | $10,631 |
| $275,000+ | $69,000 (cap) | $7,000 | +$62,000 | $17,250 (at 25%) |
The SEP IRA is massively underused. A freelance consultant earning $150,000 can shelter $31,894 in pre-tax SEP IRA contributions — saving approximately $7,974 in federal taxes at the 25% marginal rate. That same person can only contribute $7,000 to a Roth IRA. Opening a SEP IRA at Fidelity takes 15 minutes online and could save you $6,000–$17,000+ in taxes this year alone.

SEP IRA vs Solo 401(k): Which Is Right for You?
Both accounts have the same $69,000 maximum contribution in 2026, but they work very differently. A SEP IRA is simpler — open it online in 15 minutes. A Solo 401(k) is more flexible but requires a plan document and annual IRS Form 5500 filings once the balance exceeds $250,000.
| Comparison | SEP IRA | Solo 401(k) | Winner |
|---|---|---|---|
| Annual contribution limit (2026) | $69,000 / 25% of comp | $69,000 total (employee + employer) | Tied |
| Roth contribution option | No — pre-tax only | Yes — Roth Solo 401(k) available | Solo 401(k) |
| Employee contribution (salary deferral) | No — employer contribution only | Yes — up to $23,000 employee deferral | Solo 401(k) |
| Catch-up contributions (age 50+) | No catch-up provision | +$7,500 catch-up = $76,500 total | Solo 401(k) |
| Loan against account balance | No loans permitted | Yes — borrow up to 50% or $50K | Solo 401(k) |
| Setup complexity | Extremely simple — open online, contribute | Plan document required + annual IRS Form 5500 (once >$250K) | SEP IRA |
| Can have employees | Yes — must contribute same % for eligible employees | No — must be truly self-employed with no full-time employees | — |
| Contribution deadline | Tax filing deadline (April 15, or Oct 15 with extension) | Employee deferral by Dec 31; employer by tax filing deadline | SEP IRA |
| Multiple income sources (W-2 + self-employed) | SEP based only on self-employment income | Employee deferral applies to all W-2 + self-employment income | Solo 401(k) |
| Best for | High-income self-employed who want simplicity | Lower-income self-employed who want more flexibility | Tied |
Choose SEP IRA if:
- High income — you can max out at 25% of compensation
- You want simplicity — open online in 15 minutes
- You have eligible employees you're willing to fund
- You file for extensions (April–October deadline flexibility)
- You don't need Roth contributions or loans
Choose Solo 401(k) if:
- Lower income — employee deferral lets you contribute more
- You're age 50+ and want $7,500 in catch-up contributions
- You want a Roth Solo 401(k) option
- You also have a W-2 job and want to maximize contributions
- You want the option to take a loan against the account
How to Open and Fund a SEP IRA (6 Steps)
Opening a SEP IRA at Fidelity or Schwab is genuinely simple — 15–20 minutes online, no IRS paperwork to file, and contributions can be made up until your tax filing deadline. Here's the complete process.
Confirm you qualify
Any self-employed individual can open a SEP IRA — sole proprietors, freelancers, consultants, LLC owners, S-corp owner-employees, and partnerships. You can contribute to a SEP IRA even if you also have a W-2 job with a 401(k). The SEP IRA contribution is based only on your self-employment income.
Open the SEP IRA online
Open your SEP IRA at your chosen broker — Fidelity and Schwab both allow full online opening in 15 minutes. You'll fill out a Form 5305-SEP (the IRS model SEP plan document) — your broker generates this automatically. No IRS filing required to establish a SEP IRA.
Calculate your maximum contribution
For sole proprietors: 20% of net self-employment income (after the 50% SE tax deduction). For S-corp or partnership employees: 25% of W-2 compensation from the business. The 20% vs 25% distinction is critical — make sure to use the right formula for your business structure. Your accountant can verify the exact number.
Fund the account
Transfer funds from your business checking or personal checking account directly to the SEP IRA. You can make contributions in lump sums or throughout the year — there's no requirement to contribute monthly. Contributions must be in cash (not securities). You have until your tax filing deadline (April 15, or October 15 with an extension) to contribute for the prior tax year.
Invest the contribution immediately
Once funds appear as cash in your SEP IRA, invest them right away — cash earns almost nothing compared to the long-term market. For most investors, a simple allocation of FZROX (or VTI + VXUS) is appropriate. Set a recurring reminder to invest new contributions as they arrive rather than letting cash sit uninvested.
Report contributions on your tax return
SEP IRA contributions are deductible on Schedule 1 of Form 1040 (line 16 — Self-Employed SEP). You'll receive a Form 5498 from your broker confirming the contribution amount. Keep records of all contributions. If you have employees, you must contribute the same percentage of their compensation — this is the critical employee parity rule.
Need in-person help setting up your SEP IRA?
Schwab has 350+ branches nationwide where you can sit down with a financial consultant and walk through SEP IRA setup, contribution timing, and investment selection in person. The Schwab referral bonus may also apply when opening a new account.
