Yes, you can have a SEP IRA and a Traditional IRA at the same time and contribute to both in the same year. The IRS treats them as separate accounts with independent contribution limits, so funding one does not shrink what you can put into the other. The catch isn’t whether you’re allowed to hold both. It’s that being in a SEP can reduce or eliminate the tax deduction you’d otherwise get on your Traditional IRA contributions.
Separate Limits on Separate Tracks
The Traditional IRA contribution limit for 2026 is $7,500, or your total taxable compensation for the year if that’s lower.1Internal Revenue Service. Retirement Topics – IRA Contribution Limits If you’re 50 or older by year end, you can add $1,100 as a catch-up, bringing the ceiling to $8,600. That cap applies across all your Traditional and Roth IRAs combined, not per account.
SEP IRA contributions come from the employer side, even when the employer and the employee are the same person. For 2026, the employer can put in the lesser of 25% of the employee’s compensation or $69,000, with only the first $360,000 of compensation counting toward the calculation.2Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs) Depositing $69,000 into a SEP doesn’t touch the $7,500 you can still put into a Traditional IRA.
The Self-Employment Wrinkle
If you’re self-employed, the 25% rate doesn’t work as cleanly as it does for a W-2 employee. You have to reduce your net self-employment income by half of your self-employment tax and by the SEP contribution itself before applying the rate. That creates a circular calculation: the contribution depends on the deduction, and the deduction depends on the contribution.3Internal Revenue Service. Self-Employed Individuals: Calculating Your Own Retirement Plan Contribution and Deduction The IRS publishes a rate table in Publication 560 to solve it, and the effective maximum for a self-employed person works out to roughly 20% of net self-employment earnings rather than 25%. If you assume you can set aside a full quarter of your freelance income, you’ll overshoot.
How a SEP Changes Your Traditional IRA Deduction
Being in a SEP makes you an “active participant” in a workplace retirement plan. You can still contribute to a Traditional IRA at any income level, but the tax deduction phases out as your Modified Adjusted Gross Income rises.
For 2026, the phase-out ranges are:4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single or head of household: full deduction at $81,000 or less, partial between $81,000 and $91,000, none above $91,000.
- Married filing jointly, contributor covered by a plan: full deduction at $129,000 or less, partial between $129,000 and $149,000, none above $149,000.
- Married filing jointly, contributor not covered but spouse is: full deduction at $242,000 or less, partial between $242,000 and $252,000, none above $252,000.
- Married filing separately, covered by a plan: partial deduction between $0 and $10,000, none above $10,000.
That last category catches people off guard. If you’re married, file separately, and participate in a SEP, the deduction disappears almost immediately.
What to Do When the Contribution Is Not Deductible
Above these thresholds, your Traditional IRA contributions become non-deductible. You can still make them, but you have to report the after-tax basis on IRS Form 8606.5Internal Revenue Service. About Form 8606, Nondeductible IRAs Skipping the form is a common mistake with a real consequence: without it, the IRS has no record that you already paid tax on those dollars, and you risk being taxed on them again when you withdraw in retirement. If you’re in this situation across multiple years, keep those 8606 filings indefinitely.
Different Deadlines for Each Account
Traditional IRA contributions for a given tax year must be made by the tax filing deadline, which is typically April 15 of the following year. Extending your return does not extend the IRA contribution deadline.
SEP contributions run on a more generous timeline. You have until the due date of your federal income tax return, including extensions, to deposit them for that year.6Internal Revenue Service. Retirement Plans FAQs Regarding SEPs File for a six-month extension and you have until October 15 to fund the SEP. For a self-employed person, that gap is a real planning advantage: you can finish the tax picture before deciding how much the SEP should absorb.
The Excess Contribution Risk of Running Two Accounts
Contributing more than the allowed amount to either account triggers a 6% excise tax on the excess for every year it stays in the account.1Internal Revenue Service. Retirement Topics – IRA Contribution Limits Two accounts double the chances of tripping this. If you lose track and exceed the $7,500 Traditional IRA limit, or if you miscalculate the SEP contribution against net self-employment income, the 6% tax compounds annually until you fix it.
To avoid the penalty, withdraw the excess and any earnings on it before your tax return due date, including extensions. On the SEP side, if the employer overcontributes, the excess can be distributed back to the employer and reported on Form 1099-R with a taxable amount of zero.7Internal Revenue Service. Contributions to the SEP-IRA Exceeded the Maximum Legal Limits The correction is straightforward if you catch it before filing and more expensive after.
Who Qualifies for Each
A Traditional IRA is open to anyone with taxable compensation: wages, salary, tips, self-employment income, or similar earnings. There is no age limit as long as you have earned income. Passive income like interest, dividends, or rent doesn’t count.
A SEP requires self-employment income or business ownership. If you have employees, you generally must include anyone who meets all three of these conditions:6Internal Revenue Service. Retirement Plans FAQs Regarding SEPs
- At least 21 years old.
- Worked for your business in at least three of the last five years.
- Received at least $800 in compensation from your business during the year.
You can set less restrictive requirements, such as covering employees after one year of service, but you cannot make the criteria stricter. Whatever contribution percentage you choose for yourself, you have to apply the same rate to every eligible employee. That equal-treatment rule is the hidden cost of a SEP for a business with staff: a 25% contribution for you means 25% for each qualifying employee as well.
