Retirement Plans for Tutors: Solo 401(k) for Independent Tutors and Plans for Test Prep Companies
Independent tutors are well-positioned for the Solo 401(k) because most operate without employees. A tutor who works one-on-one with students (in person or online), manages their own schedule, and uses no assistants or employees can contribute the maximum to a Solo 401(k). Test prep companies that hire tutors as W-2 employees face the same multi-employee plan challenge as other small businesses.
An independent tutor with no employees (other than a spouse) uses the Solo 401(k): $23,500 employee deferral plus 20% of net SE income (or 25% of W-2 salary from an S-Corp). A tutor earning $70,000 in net profit can contribute approximately $36,500 ($23,500 deferral + $13,000 employer contribution). This shelters more than half of the tutor’s net income, dramatically reducing the current-year tax bill. Test prep company owners with W-2 tutors must use a plan that covers employees. The SIMPLE IRA is the most common choice because tutoring employees (often part-time, college students or graduate students) have high turnover and may not meet the eligibility requirements ($5,000 in any two prior years). The Safe Harbor 401(k) is better for established companies with longer-tenured tutors. Tutors who work as independent contractors for test prep companies have their OWN Solo 401(k) (their contract income is self-employment income), separate from any plan the company offers.
How much can an independent tutor contribute?
What about online tutors with course income?
An online tutor who also sells recorded courses (on Udemy, Teachable, or their own platform) has two income streams: live tutoring (active income) and course sales (still self-employment income, not passive). Both are included in QBI. Both are included in the net SE income calculation for the Solo 401(k) employer contribution.
The course income doesn’t change the plan structure. It simply increases the total net profit, which increases the available employer contribution (up to the $70,000 combined limit).

Can a tutor contribute to both an employer 401(k) and a solo 401(k)?
Yes, but with limits. If you have a W-2 job with a 401(k) and also earn self-employment income from tutoring, the $23,000 employee deferral limit (2024, $30,500 if age 50+) is a combined cap across all 401(k) plans. However, the employer profit-sharing contribution (up to 20% of net self-employment income, the effective self-employed rate) to your solo 401(k) is separate and does not count against the employee deferral limit. The total combined contribution across all plans cannot exceed $69,000 ($76,500 if 50+) for 2024. For tutors with modest side income, a SEP-IRA may be simpler because it avoids the combined-deferral tracking, though it limits you to employer-only contributions of up to 20% of net self-employment income.
What deadlines apply to a tutor’s Solo 401(k)?
An independent tutor with an existing Solo 401(k) elects employee deferrals by December 31 and can deposit them, plus the employer contribution, by the return due date with extensions: October 15, 2026 for a 2025 sole proprietor who files Form 4868. A tutor who works through an S corporation follows the S corp’s return due date instead.
A tutor with no employees, spouse included, who never opened a plan in 2025 can adopt one after year-end and make 2025 deferrals by April 15, 2026, with no extension. That option isn’t open to S corporations.
- A tutor who also has a W-2 job with a 401(k) shares one deferral limit across both plans: $23,500 for 2025 and $24,500 for 2026.
- A test prep company putting W-2 tutors on a SIMPLE IRA has to make it effective by October 1, and deposit tutors’ deferrals no later than 30 days after the end of the month they’re withheld.
When should a tutor start saving for retirement?
As soon as you have consistent net self-employment income, even if the amounts are small. The power of compounding means starting early with small contributions outperforms starting later with large ones. A Roth IRA requires no minimum contribution and is ideal for tutors in lower tax brackets: you pay tax on the contribution now (when your rate is low) and withdraw tax-free in retirement. If your tutoring income grows beyond $50,000 net, a solo 401(k) allows much larger contributions ($23,500 employee deferral for 2025 plus an employer contribution of about 20% of net SE income) and includes a Roth option. The contribution deadline for IRAs is April 15 of the following year for most people, even if you extend your return, which still gives you time to make a prior-year contribution based on actual income. Even $200 per month into a Roth IRA, growing at a historical 7% return, reaches approximately $120,000 in 20 years. Start small and increase as income allows.
