What’s the difference between a Solo 401(k) and a SEP IRA?
A SEP IRA contribution is employer-only (about 20% of net self-employment earnings). A Solo 401(k) adds an employee elective deferral on top of the employer portion, so at lower-to-moderate incomes it usually allows a larger total contribution. Both are capped at the overall limit ($72,000 for 2026), with catch-up contributions on top for a Solo 401(k) at 50+.
Which is better for a gig worker?
It depends on your income and goals. Solo 401(k)s often allow more at moderate incomes and offer a Roth option and loans; SEP IRAs are simpler to open. This calculator compares the limits, consult a tax professional for your situation.
What is the 2026 Solo 401(k) contribution limit?
$72,000 combined employee and employer contributions, up from $70,000 in 2025. The employee deferral is $24,500. At 50 and over you can add an $8,000 catch-up, or $11,250 at ages 60 to 63. Source: IRS Notice 2025-67.
How much profit do I need to max out a Solo 401(k) in 2026?
As a sole proprietor, the employer side is about 20% of net self-employment earnings (profit minus half of self-employment tax). To reach $72,000 you need the $24,500 deferral plus $47,500 of employer contribution, which takes roughly $255,000 of net profit. This calculator shows your exact number.
I'm a consultant earning $150,000. How much can I contribute?
On about $150,000 of net profit, a Solo 401(k) allows roughly $52,400 (the $24,500 deferral plus about $27,900 employer contribution), versus about $27,900 in a SEP IRA. Enter your own profit above for your figure.
Can I have a Solo 401(k) if I also have a W-2 job with a 401(k)?
Yes, but the $24,500 employee deferral is shared across every 401(k) you contribute to in the year. The employer profit-sharing side of your Solo 401(k) is separate and still available.
