Why 20% (not 25%)?
The Self-Employed SEP IRA Math
The 25% rate applies to compensation AFTER the SEP IRA contribution is deducted. For a W-2 employee, this works naturally — the employer adds 25% on top of wages. For self-employed individuals, the contribution reduces your net earnings, creating a circular calculation.
The algebraic solution:
Contribution = 25% × (Net earnings − Contribution)
→ Contribution = Net earnings × 25%/125% = Net earnings × 20%
Bottom line: as a sole proprietor, you contribute ~20% of net SE earnings, capped at $72,000.
FAQ
Common Questions
Who can open a SEP IRA?
Any self-employed individual, sole proprietor, partnership, or small business owner can open a SEP IRA. There are no employee count restrictions. If you have employees who meet eligibility requirements (age 21, worked 3 of last 5 years, earned at least $750 in 2026), you must contribute the same percentage of pay for all eligible employees as for yourself.
SEP IRA vs Solo 401(k) — which is better?
For self-employed individuals with no employees, the Solo 401(k) usually allows higher contributions because you can contribute both as employee ($24,500) and employer (~20% of net SE). SEP IRA is simpler — no annual Form 5500 filing — and easier to set up. See full comparison →
When is the deadline to contribute to a SEP IRA?
You have until your business tax filing deadline (including extensions) to establish and fund a SEP IRA for the prior year. For most businesses, that's April 15 of the following year, or October 15 with an extension. This is one of the SEP IRA's biggest advantages — you can wait until you know your final profit.
Can SEP IRA contributions be Roth?
Under SECURE 2.0, SEP IRAs can now offer a Roth option (effective 2023+), but implementation depends on your plan provider. Most providers still only offer traditional (pre-tax) SEP contributions. Roth SEP contributions are made with after-tax dollars but grow tax-free.
