Monitor Contributions and Tax Treatment
Our platform allows you to monitor your contributions, broken down by type. For example pre-tax contributions are tax-deductible, but withdrawals in retirement are taxed as income.
Roth Solo 401(k) contributions are made in after-tax dollars and are not tax deductible. However, withdrawals in retirement are completely tax-free. Proper recordkeeping is important to make sure you get the tax break at retirement.
Solo 401(k) Contribution Limits
2025 - 2026 Employer Contribution Limits
Total contributions to a participant’s account, not counting catch-up contributions (50 or older), may not exceed the maximum allowed for the tax year. The maximum is the lesser of 25% of an employee's compensation up to the maximum limit of $70,000 in 2025 and $72,000 in 2026. Employees and employer contributions combined may not exceed this limit.
2025 - 2026 Employee Elective Deferrals / Employee Contributions
The maximum an employee can contribute to a Solo 401(k) from employment income is $23,500 in 2025 and $24,500 in 2026 with an additional catch-up of $7,500 if over age 50 in 2025 and $8,000 in 2026. If age 60-63 additional catch up contribution is $11,250 for both 2025 and 2026. This is all tracked and calculated by our platform.
