What is a SEP IRA?
The IRS says a SEP plan allows employers to contribute to traditional IRAs (SEP-IRAs) set up for employees, and a business of any size, even self-employed, can establish a SEP. (Source: IRS.gov, page last reviewed or updated May 7, 2026, checked Oct 24, 2026.)
What is a Solo 401(k)?
The IRS calls it a one-participant 401(k) plan: a traditional 401(k) plan covering a business owner with no employees, or that person and his or her spouse. It has the same rules and requirements as any other 401(k) plan. (Source: IRS.gov, page last reviewed or updated Apr 9, 2026, checked Oct 24, 2026.)
