Many aspiring entrepreneurs dream of setting up the ultimate retirement plan – a solo 401k – even before they make their first dollar. But is it possible to open a solo 401k with zero income? This common question often trips up new business owners. Let’s break down the REAL minimum income requirements and eligibility criteria for a solo 401k.
The Top 3 Minimum Income Scenarios for a Solo 401k
- Making Contributions
To make solo 401k contributions, you need earned income. After all, you can’t contribute money you haven’t made! Specifically, you need self-employment income reported on your taxes:
- For sole proprietors – Schedule C
- For S-corp owners – W-2 wages
- For a self-employed business taxed as a partnership – income reported on Line 14 of the K-1
The more income you earn, the higher your contribution limits (up to $69,000 per year for 2024 plus an additional $7500 if age 50 or older).
- Taking a Loan
To take a solo 401k loan, you simply need to legitimately report self-employment income. Many entrepreneurs use 401k loans to help launch their startup before profits roll in. As long as you have verifiable earned self-employment income on your tax return and no full-time W-2 employees working for any business owned by you (or a spouse if any), you can tap up to 50% of your solo 401k balance (not to exceed $50,000) as a loan.
- Opening an Account
To open a solo 401k account, you need to be self-employed and report earned income — there are no technical dollar minimums to check the “self-employed” box (i.e. solo 401k plans are not just for high-earning self-employed individuals).
Busting Myths: You DO NOT Need…
- High Profits or Revenue
- A full-time business
- Minimum Solo 401k contributions
The Bottom Line
Solo 401k eligibility depends more on your employment and tax status rather than your income level. As long as you have verifiable self-employment income to report (with no full-time non-owner/non-spouse w-2 employees working for any business owned by you or a spouse (if any)), you can take advantage of the ultimate retirement account for self-employed individuals.
