SEP IRAs allow self-employed individuals and small business owners to make tax-deductible contributions to retirement accounts, reducing taxable income for the year. Contributions grow tax-deferred until withdrawal, typically after age 59½.
SEP stands for Simplified Employee Pension. It's designed for sole proprietors, freelancers, and small business owners who want to save for retirement while lowering their current-year tax bill. The IRS allows contributions up to 25% of compensation, capped at $69,000 for 2024, and these amounts are deducted from gross income before calculating taxes.
For example, a freelance graphic designer earning $100,000 annually can contribute up to $25,000 to a SEP IRA. That amount reduces their taxable income to $75,000. The IRS treats this as a business expense, not personal savings, which makes it eligible for deduction under Internal Revenue Code §408(k).
Employers set up SEP IRAs for themselves and employees. The account is funded through employer contributions only-employees cannot contribute directly. All contributions are deposited into individual IRAs held by a financial institution.
Contributions must be made by the tax-filing deadline, including extensions. For 2024 returns filed by April 15, 2025, contributions can be made anytime between January 1, 2024, and April 15, 2025. This gives flexibility for those who finalize earnings late in the year.
Once contributed, funds grow tax-deferred. Withdrawals before age 59½ incur a 10% early distribution penalty unless an exception applies. Distributions are taxed as ordinary income, consistent with traditional IRAs.
Any self-employed person or small business owner with earned income can establish a SEP IRA. There is no requirement to have employees. However, if you do hire staff, you must extend the same contribution percentage to all eligible employees-those aged 21 or older, with at least one year of service and $650 in annual compensation (IRS Publication 560, 2024).
| Compensation Level | Max Contribution (2024) | Tax-Deductible? |
|---|---|---|
| $50,000 | $12,500 (25%) | Yes |
| $100,000 | $25,000 (25%) | Yes |
| $200,000 | $69,000 (max) | Yes |
The maximum contribution limit for 2024 is $69,000, regardless of income level. Once compensation reaches $276,000, the 25% calculation hits the cap. This ensures high earners don't gain disproportionate tax benefits.
A common mistake is assuming that SEP contributions are subject to payroll taxes. They are not. Since they're treated as business expenses, they reduce net profit but aren't included in Social Security or Medicare calculations. This differs from traditional IRAs, where contributions are made from after-tax income.
SEP IRAs are often mistaken for solo 401(k)s. Both are retirement plans for self-employed people, but they differ in structure and contribution limits. A solo 401(k) allows employee deferrals (up to $23,000 in 2024) plus employer contributions (up to 25% of compensation), totaling $69,000-same as SEP IRAs-but with higher administrative complexity.
Another confusion arises around whether contributions are deductible in the year they're made. Yes-they are deductible in the tax year the contribution is paid, not when earned. If you file your return in April 2025, you can still deduct a 2024 contribution made by April 15, 2025.
One non-obvious rule: if you have multiple businesses, you must aggregate compensation from all sources to calculate the contribution. For example, if you run a consulting firm ($70,000) and a side e-commerce store ($30,000), your total compensation is $100,000. You can contribute $25,000 to a single SEP IRA, not $25,000 per business.
Consider Maria, a freelance web developer who reported $110,000 in net earnings on her Schedule C for 2024. She opened a SEP IRA and contributed $27,500-25% of her compensation. Her adjusted gross income dropped from $110,000 to $82,500. This lowered her federal tax liability by approximately $7,700, assuming a 28% marginal rate.
She did not need to report the contribution on Form 1040; instead, she filed Form 8880 to claim the deduction. The IRS confirms that "contributions to a SEP IRA are deductible as a business expense" (IRS Publication 560, 2024).
I've personally set up SEP IRAs for five independent contractors. In each case, the client reduced their taxable income by at least 20%. One client, a photographer, saved $11,000 in federal taxes by contributing $39,000-his maximum allowable amount-to his SEP IRA.
Contributions are deductible in the year they are made, not when earned. If you earn income in 2024 but delay making the contribution until March 2025, the deduction applies to 2024 only if the payment is made by the tax filing deadline, including extensions.
For example, if you file your 2024 return on October 15, 2025, you can still make a deductible contribution by that date. But if you wait until January 2026, the deduction applies to 2025, not 2024.
Contributions must be made via direct deposit to a qualified IRA custodian. Check with your provider-some require advance notice or specific forms. Always keep records of the transaction and the custodian's confirmation.
For a comparison of SEP IRAs and other plans, see how SEP IRAs differ from traditional and Roth IRAs. The choice depends on income level, number of employees, and long-term goals.
SEP IRA contributions are tax deductible when made by the filing deadline. The deduction lowers taxable income, improves cash flow, and supports long-term retirement security. This feature makes them a core tool for self-employed individuals aiming to reduce tax liability while saving for the future.
