Frequently Asked Questions

Generally no โ€” you can only have one or the other (not both) for the same business. However, you can have a Solo 401(k) for your self-employment income AND contribute to a regular IRA or Roth IRA separately. If you have multiple businesses, the rules get more complex โ€” consult a tax advisor.
SEP-IRA and traditional Solo 401(k) contributions are tax-deductible โ€” they reduce your AGI directly. However, they do NOT reduce your SE tax base (SE tax is calculated before these deductions). A $10,000 SEP-IRA contribution at a 30% total tax rate saves you about $3,000 in income taxes. They do NOT save on SE tax.
A common rule of thumb is 15% of gross income. But freelancers have no employer match and may have higher tax burdens โ€” many financial advisors recommend 20โ€“25% for self-employed. Use the calculator above to work backward: decide what monthly income you want in retirement, estimate a safe withdrawal rate (4% rule), and calculate the portfolio size you need.
