A SEP-IRA can help self-employed people reduce taxable income while saving for retirement. Here's how it works and how to estimate your maximum contribution.
A SEP-IRA, short for Simplified Employee Pension IRA, is a retirement plan used by many self-employed people and small business owners. It is popular because it is easier to administer than many employer plans and can allow larger deductible contributions than a regular traditional IRA. For profitable freelancers, consultants, designers, developers, real estate professionals, and solo business owners, a SEP-IRA can turn part of today's business profit into long-term retirement savings.
SEP-IRA rules are detailed, and the annual dollar cap can change. Because we could not confirm a final IRS 2026 SEP dollar limit from an official IRS page while preparing this article, verify the current limit in IRS Publication 560 and the IRS SEP resources before funding. The general structure is that employer SEP contributions are limited by a percentage of compensation and an annual dollar cap. For self-employed people, the calculation is not simply 25% of Schedule C profit because the contribution itself and the self-employment tax deduction affect the formula.
Who qualifies for a SEP-IRA?
Sole proprietors, independent contractors, partnerships, LLC owners taxed as sole proprietors or partnerships, and corporations can use SEP plans when they meet the rules. If you have employees, you must pay close attention to eligibility and equal-percentage contribution requirements. A solo freelancer with no employees has a simpler situation, but still needs to calculate the maximum contribution correctly.
How the deduction works
SEP contributions are generally deductible for income tax purposes, which can reduce taxable income dollar for dollar. A key nuance: retirement plan contributions usually reduce income tax, but they do not directly reduce self-employment tax for the year. Self-employment tax is calculated from net earnings from self-employment before the SEP contribution deduction. This is one reason quarterly estimates should separate income tax planning from self-employment tax planning.
Example contribution calculation
Suppose a freelancer has $120,000 of gross income and $15,000 of deductible business expenses. Net profit starts at $105,000. The freelancer calculates self-employment tax and the deduction for one-half of self-employment tax. The maximum SEP contribution is then based on the self-employed retirement plan formula, commonly approximated around 20% of adjusted net earnings, subject to the IRS annual dollar cap. The final number should be checked with tax software, a tax professional, or the worksheet in Publication 560.
When using the MyTaxQuarter calculator, enter income and expenses first to estimate quarterly tax before retirement contributions. Then model SEP contributions as other deductions only for income tax planning. Do not double-count the automatic self-employment tax deduction. For additional estimated-tax context, see our quarterly tax FAQ.
Deadline for 2026 contributions
SEP-IRA contributions can generally be made by the tax filing deadline for the business, including extensions. For many individual sole proprietors, that can mean as late as October 15, 2027 for the 2026 tax year if a valid extension is filed. The ability to decide after year-end is one reason SEP-IRAs are useful for freelancers with variable income.
