For self-employed individuals and small business owners, SEP IRAs and Solo 401(k)s offer powerful, tax-advantaged retirement savings beyond traditional IRAs. SEP IRAs are simpler to set up and ideal for businesses with employees, while Solo 401(k)s allow higher contributions and catch-up options for owners with no employees. Each has unique rules and benefits—consult a Whitaker-Myers advisor to choose the best fit for your retirement goals.
