Understanding Your SEP IRA Contributions

A Simplified Employee Pension (SEP) IRA is a retirement plan designed for self-employed individuals and small business owners. It allows employers to contribute to traditional IRAs set up for themselves and their eligible employees. Unlike a traditional IRA, contributions to a SEP IRA are made solely by the employer, and they are tax-deductible for the business.

Who Can Use a SEP IRA?

SEP IRAs are particularly attractive for:

  • Self-employed individuals: Freelancers, independent contractors, and sole proprietors.
  • Small business owners: Businesses with one or more employees, including S-Corps and C-Corps.

They offer a simpler alternative to more complex plans like 401(k)s, with lower administrative costs and fewer reporting requirements.

How SEP IRA Contributions Work

The amount an employer can contribute to a SEP IRA is flexible and can vary from year to year. The maximum contribution is generally the lesser of:

  1. 25% of an employee's compensation (or 20% of net self-employment earnings for self-employed individuals).
  2. A dollar limit set by the IRS for the tax year (e.g., $69,000 for 2024).

For self-employed individuals, calculating "compensation" can be a bit tricky. The IRS defines it as your net earnings from self-employment minus one-half of your self-employment taxes, and minus the SEP contribution itself. To simplify this circular calculation, the effective contribution rate for self-employed individuals is often considered to be 20% of your net self-employment earnings (before deducting the SEP contribution).

Using the Calculator

This calculator helps self-employed individuals determine their maximum allowable SEP IRA contribution. Here's what each input means:

  • Net Self-Employment Income: This is your business's profit after all business expenses but before deducting your SEP IRA contribution. For sole proprietors, this is typically your net profit from Schedule C, Line 31.
  • Employer Contribution Rate: This is the percentage you, as the employer, choose to contribute. The maximum allowed by the IRS is 25% of an employee's compensation. For self-employed, this 25% rate effectively translates to 20% of your net self-employment income due to the calculation methodology.
  • IRS Annual Contribution Limit: The IRS sets a maximum dollar amount that can be contributed to a SEP IRA each year. This limit changes periodically (e.g., $69,000 for 2024).

Example Calculation:

Let's say you are a self-employed individual with:

  • Net Self-Employment Income: $100,000
  • Desired Employer Contribution Rate: 20%
  • IRS Annual Contribution Limit: $69,000 (for 2024)

Using the calculator:

  1. Convert desired rate to decimal: 20% = 0.20
  2. Calculate effective rate for self-employed: 0.20 / (1 + 0.20) = 0.20 / 1.20 = 0.16666… (or if using the 20% of net earnings rule, it's simply 0.20)
  3. Potential Contribution: $100,000 * 0.16666… = $16,666.67 (using the 25% of compensation rule) OR $100,000 * 0.20 = $20,000 (using the simplified 20% of net earnings rule). Our calculator uses the former, which is more precise for the "25% of compensation" rule.
  4. Compare with IRS Annual Limit: $16,666.67 vs $69,000.
  5. Your Maximum SEP IRA Contribution: $16,666.67

This calculator simplifies the process, ensuring you stay within IRS guidelines while maximizing your retirement savings.
