The SEP IRA contribution limit is the lesser of 25% of eligible compensation or $70,000 for the 2025 tax year and $72,000 for 2026. For self-employed individuals filing Schedule C, the effective contribution ceiling is roughly 20% of net self-employment earnings after subtracting half of self-employment tax. All contributions must be funded strictly by the employer, with equal percentages provided for all eligible employees.
SEP IRA contribution limits are the IRS annual cap on employer-funded contributions to a Simplified Employee Pension account, restricted to the lesser of 25% of eligible compensation or $70,000 in 2025 and $72,000 in 2026.
If you earn self-employment income or run a small business, sheltering profits in a tax-deferred wrapper allows your portfolio to compound without annual tax drag. Selecting the wrong calculation method or ignoring employee eligibility, however, can trigger severe IRS penalties. Below is a breakdown of maximum annual caps, self-employed deduction mechanics, and long-term cost trade-offs.
Quick Takeaways
01The maximum dollar limit for SEP IRA contributions is $70,000 for 2025 and $72,000 for 2026.
02Standard employer contributions are capped at 25% of W-2 gross pay or an effective 20% of net self-employment earnings.
03SEP IRAs are funded exclusively by employers; employees cannot make elective salary deferrals into a traditional SEP IRA.
04Business owners who contribute for themselves must contribute an equal percentage of compensation for all eligible employees.
05Unlike traditional or Roth IRAs, SEP IRAs do not allow catch-up contributions at age 50 or older.
What Is a SEP IRA and How Do Contribution Caps Work?
A Simplified Employee Pension (SEP IRA) is an employer-sponsored retirement account wrapper that allows business owners and self-employed individuals to make tax-deductible contributions into individual retirement accounts.
Under IRS guidelines, funding for a traditional SEP IRA is strictly employer-paid. Employees do not make voluntary paycheck deductions or elective deferrals into the plan. Instead, the business funds the entire contribution out of business revenue, deducting the expense from corporate or sole proprietorship taxes.
One of the defining advantages of a SEP IRA is flexibility. Employers aren't locked into a fixed annual funding obligation. You can adjust your contribution rate anywhere from 0% to 25% of eligible compensation each tax year based on business cash flow. In high-profit years, you can max out the account to reduce tax exposure; during lean years, you can pause contributions entirely without terminating the plan. If you hold funds in older employer plans like a 401(k) from prior corporate employment, managing those assets alongside your business accounts often involves initiating a 401(k) rollover to an IRA to keep tax-advantaged savings consolidated.
SEP IRA Contribution Limits for 2025 and 2026
Annual SEP IRA contribution limits are determined by two ceiling figures set by the IRS: a percentage cap of eligible compensation and an absolute dollar ceiling. Your maximum permitted contribution is always whichever of these two amounts is smaller.
For the 2025 tax year, the maximum contribution limit is 25% of eligible compensation or $70,000. The IRS caps the maximum eligible compensation that can be factored into this math at $350,000.
For the 2026 tax year, inflation adjustments raise the dollar ceiling: the maximum limit is 25% of eligible compensation or $72,000. The maximum compensation base considered for calculations rises to $360,000.

How these limits apply depends directly on your legal business entity. If your business operates as an S-Corporation or C-Corporation, compensation means W-2 salaries. Shareholder distributions and dividend payouts do not count toward your compensation base. For example, if an S-Corp owner pays themselves a $100,000 W-2 salary in 2026, the company's maximum SEP contribution for that owner is $25,000 (25% of $100,000).
Calculating Self-Employed Limits: The Net Profit Formula
Self-employed sole proprietors and single-member LLCs calculate SEP IRA limits using net self-employment earnings rather than gross business profits or W-2 wages.
Because the IRS requires you to deduct your SEP contribution from your business income before calculating the final allowed percentage, applying a flat 25% multiplier to gross Schedule C income leads to an over-contribution error. To account for this circular reduction, the effective percentage cap for self-employed net earnings drops to 20% (0.20).
The step-by-step formula for a sole proprietor works as follows:
Calculate Net Income: Take your net profit from IRS Schedule C.
Subtract Half of Self-Employment Tax: Deduct the 50% portion of your self-employment tax deduction (from Schedule 1) to find your modified net business income.
Apply the 20% Rate: Multiply that modified income figure by 20% to reach your maximum permitted contribution.
For example, if a sole proprietor earns $100,000 in Schedule C net income in 2026 and has $7,100 in deductible self-employment tax:
Modified Net Income Base: $100,000 - $7,100 = $92,900
Max SEP IRA Contribution (20%): $92,900 × 0.20 = $18,580
10-Year Tax Compounding vs. The Employee Parity Obligation
Evaluating a SEP IRA requires looking at the long-term compounding benefits of pre-tax investing alongside the potential cost obligations of hiring staff.
The 10-Year Tax Compounding Effect
Sheltering high business income in a pre-tax wrapper creates significant long-term structural value compared to investing in a taxable brokerage account. Consider an illustrative case of a solo business owner who contributes $50,000 annually into long-term equity index funds:
In a Taxable Brokerage Account: If that $50,000 is taxed upfront at a 32% marginal rate, only $34,000 enters the market each year. Over 10 years, assuming a 7% nominal annual return, taxes on annual dividends and realized gains further drag compounding down. The portfolio grows to approximately $470,000.
In a SEP IRA Wrapper: The full $50,000 is invested tax-deferred every year. Assuming the same 7% annual return, the account grows to approximately $690,000 over 10 years.
Note: This is a hypothetical illustration only — actual market returns are not guaranteed and can vary significantly.
By deferring income taxes during your peak earning decade, you keep an extra ~$220,000 working inside your portfolio. Over long horizons, avoiding annual tax friction is one of the most powerful tools for accelerating wealth accumulation.
The Employee Parity Rule Trap
The financial math changes significantly if your business employs staff. Under IRS rules, if an employer contributes to a SEP IRA for themselves, they must provide equal contribution percentages for all eligible employees.
An eligible employee is generally someone who:
Is at least 21 years old.
Has worked for your business in at least 3 of the last 5 years.
Earned at least $750 in compensation for 2025 (rising to $800 for 2026).
If you decide to contribute 15% of your W-2 wage into your SEP IRA, you are legally obligated to contribute 15% of every eligible employee’s salary into their respective SEP IRAs out of company funds. If you have three staff members earning $60,000 each ($180,000 total payroll), a 15% contribution for yourself creates an additional mandatory employer outlay of $27,000 for your staff. For businesses with expanding staff counts, this parity rule can dramatically alter the true 10-year cost of maintaining a SEP plan compared to alternative structures like a Solo 401(k).
Common SEP IRA Pitfalls and Limits Misconceptions
Misinterpreting IRS account rules can lead to unexpected tax liabilities or missed savings opportunities.
No Catch-Up Contributions at Age 50+
Unlike personal IRAs or 401(k) plans, standard SEP IRAs do not allow catch-up contributions for individuals aged 50 or older. The overall percentage and dollar limits apply identically whether you are 30 or 60 years old. If you want to contribute additional retirement dollars as an individual, you can open and fund a separate individual retirement account, such as exploring what is a roth ira to build tax-free withdrawal streams alongside your pre-tax SEP balances.
Flexible Contribution Deadlines
A major administrative benefit of the SEP IRA is its funding deadline. Employers have until their federal income tax filing deadline—including official extensions—to establish and fund the account for the preceding tax year. For a sole proprietor or S-Corp on extension, you have until October 15 to calculate final net profits and deposit your SEP contributions, offering maximum cash-flow flexibility.
Combining SEP IRAs with Personal IRAs
Contributing to a SEP IRA as an employer does not prevent you from making personal contributions to a Traditional or Roth IRA in the same year. However, active participation in an employer-sponsored SEP IRA triggers IRS income-phaseout rules that may reduce or eliminate the tax deductibility of traditional IRA contributions on your personal return.
Conclusion
SEP IRA contribution limits offer business owners a high-ceiling retirement savings vehicle, capping out at $70,000 for 2025 and $72,000 for 2026. While W-2 wages allow a direct 25% contribution, self-employed sole proprietors must use the adjusted 20% net earnings calculation to avoid over-funding penalties. Sheltering tens of thousands of dollars each year creates substantial pre-tax compounding benefits over a 10-year horizon, but business owners with staff must carefully account for the mandatory employee parity rule.

FAQ
4 questions
What is a SEP IRA and what is the maximum contribution limit?
A SEP IRA is a retirement account designed for business owners and self-employed individuals. The contribution limit is capped at 25% of an employee's eligible compensation or $69,000 (for 2024), whichever amount is lower.
Can employees contribute their own money to a SEP IRA?
No. Only the employer can make deposits into a SEP IRA. Employees cannot add their own salary contributions, but they own 100% of the funds in the account as soon as the employer deposits them.
What is the annual deadline to make a SEP IRA contribution?
Employer contributions must be made by the business’s tax filing deadline, including any formal tax extensions. For most sole proprietors, this deadline is April 15 of the following year (or October 15 with an extension).
Are there catch-up contributions for people over 50 in a SEP IRA?
Traditional SEP IRAs do not allow catch-up contributions for investors aged 50 and older. This is because all contributions are made solely by the employer rather than through individual employee payroll deferrals.
