In a word, yes. A limited liability company (LLC) is eligible to establish a simplified employee pension (SEP). Keep in mind that plan contributions (including SEPs) are usually based on W-2 wages if the business is a corporation. This means that you may need to pay yourself W-2 wages in order to be eligible to receive an SEP contribution from the business. Check with your tax professional to be sure.
Contributions may be as much as 25% of your compensation, and they may not exceed $41,000 (for 2004). For unincorporated businesses such as sole proprietorships, partnerships and limited liability partnerships (LLPs), plan contributions may be up to 20% of the business owner's modified net profit. Should you decide to hire employees, they must also be covered under the plan if they meet the eligibility requirements.
