SEP-IRA (Simplified Employee Pension)

A SEP-IRA is a tax-deferred retirement account for self-employed individuals and small business owners. Contribution limits are far higher than a traditional IRA — up to 25% of net self-employment income, capped at $70,000 in 2025.

Formula
Max contribution = min(25% × net self-employment income, $70,000)
Example

Freelancer earning $120,000 net can contribute up to $30,000 to a SEP-IRA in 2025, reducing taxable income by the same amount.

SEP-IRAs are one of the best retirement tools for sole proprietors and freelancers because of the high contribution limit. Unlike a 401(k), there is no Roth option and no employee contribution — only employer contributions (made by the business owner on behalf of themselves).

Contributions are tax-deductible as a business expense, reducing both income tax and self-employment tax. Investments grow tax-deferred; withdrawals in retirement are taxed as ordinary income (same as traditional IRA).

Setup is simple — no annual filing with the IRS (unlike a 401(k)), and you can open one as late as the tax filing deadline (including extensions) for the prior tax year.
