SEP IRA Contribution Limits 2025 — What Small Business Owners Need to Know

One of the most powerful tools for building retirement wealth and reducing taxable income is the SEP IRA (Simplified Employee Pension Individual Retirement Account).

The IRS recently released the updated contribution limits for 2025, and there are key changes every business owner should be aware of. In this article, the experts at Planit CPA in South Jersey explain how SEP IRAs work, the new limits for 2025, and strategies for maximizing your contributions while staying compliant.

What Is a SEP IRA and Who Can Use It?

A SEP IRA is a type of retirement plan designed specifically for small businesses, freelancers, and self-employed individuals.

Key benefits include:

  • High contribution limits: Much higher than traditional or Roth IRAs.

  • Flexible contributions: You don’t have to contribute every year, which is helpful if your income fluctuates.

  • Tax-deductible contributions: Contributions are tax-deductible for the business, reducing taxable income.

  • Easy administration: Fewer reporting and compliance requirements than 401(k) plans.

Eligibility:

  • Any business owner, including sole proprietors, partnerships, and corporations.

  • Must include all eligible employees in the plan, not just the owner.

 

 

2025 SEP IRA Contribution Limits

For 2025, the IRS has adjusted the contribution limits to reflect inflation.

Category

2024 Limit

2025 Limit

Maximum contribution (employer)

$69,000

$71,000

Percentage of compensation allowed

25% of compensation

25% of compensation

Compensation limit for calculations

$345,000

$350,000

What this means:

  • The maximum total contribution for 2025 is $71,000 per individual.

  • Contributions can be up to 25% of an employee’s compensation.

  • When calculating that percentage, you only consider up to $350,000 of an employee’s pay.

How to Calculate Your SEP Contribution

The math can get tricky for self-employed individuals because you must account for self-employment tax when determining net earnings.

Example: Sole Proprietor Earning $120,000

  1. Start with $120,000 net business income.

  2. Subtract half of self-employment tax (~$8,478).

  3. Resulting net earnings: $111,522.

  4. Multiply by 20% (because the effective contribution rate for self-employed is 20%, not 25%).

  5. Contribution limit = $22,304.

Tip: A CPA can run precise calculations and ensure you don’t over-contribute, which could lead to IRS penalties.

 

SEP IRA Deadlines for 2025 Contributions

One of the biggest advantages of a SEP IRA is its extended deadline flexibility:

  • You can set up and fund a SEP IRA up to the due date of your business tax return, including extensions.

  • Example: If you file for an extension and your new deadline is October 15, 2026, you have until then to make contributions for the 2025 tax year.

This makes SEP IRAs ideal for last-minute tax planning.

 

Advantages Over Other Retirement Plans

Many small business owners debate between a SEP IRA, SIMPLE IRA, or Solo 401(k). Here’s how a SEP stacks up:

Feature

SEP IRA

SIMPLE IRA

Solo 401(k)

Contribution limits

Up to $71,000

$16,000 base ($19,500 age 50+)

$23,000 employee + $46,000 employer

Admin complexity

Very low

Low

Moderate

Employee participation required?

Yes

Yes

No (owner only)

Annual filing with IRS?

No

No

Yes (Form 5500)

 

Bottom line:

  • SEP IRAs are perfect if you want high contribution limits without a lot of paperwork.

  • If you have employees, you must contribute equally for them — something to plan for carefully.

 

Strategies to Maximize SEP IRA Benefits

  1. Start contributions early in the year

  2. Don’t wait until tax time; spreading out contributions helps with cash flow.

  3. Integrate with other tax planning strategies

  4. Combine SEP contributions with deductions like Section 179 equipment write-offs for even greater savings.

  5. Review annually with your CPA

  6. Your business may grow or shrink — update contributions accordingly.

  7. Consider future growth

  8. If you anticipate hiring employees, plan ahead because you’ll need to include them in contributions.

Common SEP IRA Mistakes to Avoid

  • Missing eligible employees: Failing to include part-time workers can trigger penalties.

  • Over-contributing: Going above limits causes tax headaches.

  • Not coordinating with other retirement accounts: If you also have a 401(k) or IRA, ensure contributions align with IRS rules.
