How self-employed retirement contributions work in Florida for 2026

Florida has no state income tax. Retirement contributions save federal income tax only. The state savings shown are $0.
Solo 401(k) vs SEP-IRA comparison
The Solo 401(k) allows a larger contribution at most income levels because it adds an employee elective deferral ($24,500) before the employer profit-sharing portion. The SEP-IRA has only the employer portion (20% of net SE compensation, capped at $72,000). At very high incomes where the Solo 401(k) base also hits $72,000, the plans become equal unless you qualify for a catch-up contribution (Solo 401(k) only).
Catch-up contributions (Solo 401(k) only)
Filers age 50-59 or 64+ add $8,000 in catch-up above the §415(c) cap. Filers age 60-63 add $11,250 (SECURE 2.0 enhanced catch-up). SEP-IRA has no catch-up at any age.

Frequently asked questions
Do retirement contributions reduce self-employment tax?+
No. Solo 401(k) and SEP-IRA contributions are above-the-line deductions on Form 1040 Schedule 1, not Schedule C deductions. SE tax is calculated on Schedule C net profit before contributions. Contributions reduce federal AGI, which lowers federal income tax and most state income taxes, but SE tax is unchanged.
What is the maximum Solo 401(k) contribution for self-employed in 2026?+
The 2026 Solo 401(k) base maximum is $72,000 (§415(c)) plus catch-up: $8,000 for ages 50-59 or 64+ and $11,250 for ages 60-63 (SECURE 2.0). The employee elective deferral is $24,500. The employer portion is 20% of net SE compensation (IRS Pub 560 formula). The elective deferral plus employer contribution cannot exceed $72,000.
What is the maximum SEP-IRA contribution for 2026?+
The 2026 SEP-IRA maximum is 20% of net SE compensation (net profit minus the deductible half of SE tax), capped at $72,000. Net SE compensation is also capped at the §401(a)(17) compensation limit of $360,000. SEP-IRA has no employee deferral and no catch-up option.
Does Florida have a state income tax on retirement contributions?+
No. Florida has no individual income tax. Retirement contributions save federal income tax only. The Solo 401(k) and SEP-IRA state savings shown for Florida are $0. The federal savings (at your marginal federal bracket) remain the same as in any other state.
Should Florida freelancers still use a Solo 401(k) or SEP-IRA?+
Yes. Even without state income tax savings, the federal income tax savings from retirement contributions are substantial. At the 22% marginal bracket, a $46,000 Solo 401(k) contribution saves approximately $10,000 in federal income tax. The tax-deferred growth on the contributions is also a major benefit regardless of state.
