SEP-IRA 2026: Contribution Limits, Tax Benefits & How to Open

Important: The contribution limit is the lesser of $70,000 or 25% of your net self-employment compensation. Because of how SE compensation is calculated, most self-employed filers hit an effective ceiling around 18.587% of their Schedule C net profit.

How to Calculate Your Maximum SEP-IRA Contribution

The calculation for self-employed individuals involves a circular reference — your SEP-IRA contribution reduces your net SE income, which in turn reduces the maximum allowable contribution. Here's the step-by-step IRS-approved method:

Step-by-Step Calculation (Example: $100,000 Net Profit)

1
Net Schedule C profit: $100,000
2
Calculate SE tax: $100,000 × 92.35% × 15.3% = $14,130
3
SE tax deduction (half): $14,130 ÷ 2 = $7,065
4
Net SE income after deduction: $100,000 − $7,065 = $92,935
5
Max SEP-IRA: $92,935 × 25% = $23,234

Quick shortcut: Multiply your net Schedule C profit by 18.587% for a close estimate.

Tax Benefits of a SEP-IRA

  • 100% tax-deductible: Contributions reduce your federal and state taxable income — not just federal.
  • Does not reduce self-employment tax: The deduction only applies to income tax. Your SE tax (Social Security + Medicare) is calculated on net profit before the SEP-IRA deduction.
  • Tax-deferred growth: Investments grow without annual capital gains or dividend taxes until withdrawal.
  • Withdrawals taxed as ordinary income in retirement — ideally at a lower tax rate than your working years.

SEP-IRA Rules You Must Know

  • Must include eligible employees: If you have employees who meet the eligibility criteria (age 21+, worked 3 of last 5 years, earned $750+), you must contribute the same percentage of their compensation as your own.
  • Immediate 100% vesting: All contributions vest immediately — unlike many 401(k) plans with multi-year vesting schedules.
  • Required Minimum Distributions (RMDs) begin at age 73 under the SECURE 2.0 Act.
  • No Roth SEP-IRA option: All contributions are pre-tax. There is no after-tax Roth version.
  • Can contribute after age 73 if you are still earning self-employment income — RMDs and contributions can run simultaneously.
  • 10% early withdrawal penalty applies to distributions taken before age 59½, with standard exceptions (disability, first-home purchase up to $10,000, substantially equal payments, etc.).

SEP-IRA Contribution Deadline

Most Flexible
Open & fund after Dec 31
  • You can open AND fund a SEP-IRA up to the tax filing deadline — no need to open the account by December 31.
  • This is more flexible than a Solo 401(k), which must be established by December 31 of the tax year (though funding can come later).
  • There is no penalty for waiting until April to open and fund — just don't miss the deadline.

How to Open a SEP-IRA

  1. Get an EIN (Employer Identification Number) at IRS.gov — takes 5 minutes online. Sole proprietors can use their SSN instead, but an EIN keeps business and personal finances cleaner.
  2. Choose a brokerage — all of the major online brokers offer free SEP-IRA accounts with no annual fees (see comparison below).
  3. Complete Form 5305-SEP — this is the IRS model plan document that officially establishes your SEP. Keep it in your records; you do not file it with the IRS.
  4. Fund the account by your contribution deadline. You can make multiple contributions throughout the year, or a single lump-sum.
  5. Report on your tax return: Deduct your SEP-IRA contribution on Schedule 1, Line 16 of Form 1040.

SEP-IRA vs. Solo 401(k): Which Is Better?

SEP-IRA Advantages

  • Simpler to set up — no annual IRS filings
  • Can include W-2 employees
  • Can open and fund after December 31
  • No loan provisions needed

Solo 401(k) Advantages

  • Higher contributions at lower income levels
  • Employee elective deferrals (up to $23,500)
  • Roth option available
  • Loan provisions available
Bottom line: Solo 401(k) generally surpasses the SEP-IRA at income levels of $20,000–$30,000 and below. Above $100,000, both plans allow substantial contributions. If you have employees or prefer simplicity, choose SEP-IRA.

Frequently Asked Questions

The 2026 SEP-IRA contribution limit is $70,000, increased from $69,000 in 2025. The contribution is the lesser of $70,000 or 25% of your net self-employment compensation. Due to the SE tax deduction calculation, most self-employed individuals hit an effective ceiling of approximately 18.587% of their net Schedule C profit. You need a net profit of at least $280,700 to reach the full $70,000 limit.

Yes, but you must contribute the same percentage of compensation for all eligible employees as you contribute for yourself. Eligible employees are those who are at least 21, have worked for you in at least 3 of the last 5 years, and earned at least $750 during 2026. If you contribute 15% of your own compensation, you must put 15% of each eligible employee's salary into their SEP-IRA. This makes SEP-IRAs expensive for businesses with several employees — Solo 401(k) is only for owner-only businesses.

Yes — you can contribute to both in the same tax year. However, because a SEP-IRA is classified as a workplace retirement plan, it may phase out the deductibility of your Traditional IRA contribution based on your modified AGI. For 2026, the phase-out for single filers covered by a workplace plan starts at $79,000; for married filing jointly, it begins at $126,000. You can still contribute to a Traditional IRA (non-deductibly) or a Roth IRA regardless of SEP-IRA participation, subject to income limits.

It depends on your income and complexity tolerance. A Solo 401(k) outperforms the SEP-IRA at lower income levels (under ~$30,000) because it allows an employee elective deferral of up to $23,500 regardless of profit percentage. The SEP-IRA wins in simplicity — no annual IRS filings (no Form 5500), can include employees, and allows post-December 31 account opening. At higher income levels ($100,000+), both plans allow large contributions. See our full retirement account comparison guide for a detailed analysis.

You can open and fund a SEP-IRA for the 2026 tax year up to your tax filing deadline, including any extension. The standard deadline is April 15, 2027. If you file a tax extension (Form 4868), you have until October 15, 2027 to contribute. Unlike Solo 401(k), which must be established by December 31, 2026, a SEP-IRA can be opened at any point up to the filing deadline — making it ideal for those who decide late in the tax season to reduce their tax bill.
