Understanding SEP IRA Plans
A Simplified Employee Pension (SEP) IRA is a retirement savings plan designed for small business owners and self-employed individuals. SEP IRAs offer high contribution limits with minimal administrative requirements, making them ideal for businesses with few or no employees.
How SEP IRAs Work
- Business Setup: Employer establishes the SEP plan
- Individual Accounts: Each participant has their own IRA
- Employer Contributions: Only employer makes contributions
- Equal Treatment: Same contribution percentage for everyone
- Immediate Vesting: Employees own contributions immediately
2025 Contribution Limits
- Maximum Annual Contribution: $70,000
- Maximum Percentage: 25% of compensation
- Maximum Compensation Considered: $345,000
- Self-Employed Adjustment: Contribution rate/(1 + contribution rate)
Employee Eligibility Requirements
All employees must be included if they meet ALL of the following criteria:
- Age 21 or older
- Worked for the business in at least 3 of the last 5 years
- Received at least $750 in compensation during the year (2025 limit)
Self-Employed Contribution Calculation
The contribution calculation for self-employed individuals is more complex than for employees. You must first reduce your net self-employment earnings by half of your self-employment tax, then apply a modified contribution rate.
Step-by-Step Calculation:
- Start with net profit from Schedule C
- Subtract one-half of self-employment tax
- Apply the adjusted contribution rate: Rate ÷ (1 + Rate)
- Result cannot exceed annual maximum ($70,000 for 2025)
Advantages of SEP IRAs
- High Contribution Limits: Much higher than traditional IRAs
- Easy Setup: Minimal paperwork and administration
- Flexible Contributions: Not required to contribute every year
- Tax Deductible: Contributions reduce current taxable income
- No Required Minimums: Until age 73
- Employee Control: Participants manage their own investments
Disadvantages of SEP IRAs
- Employee Coverage: Must include all eligible employees
- Equal Contributions: Same percentage for everyone
- No Employee Contributions: Only employer can contribute
- No Loans: Cannot borrow from SEP IRA
- Limited Flexibility: Fewer options than 401(k) plans
