We found no Port St. Lucie ordinance for gig, app-based, or freelance workers. No official state list of jurisdictions without a local income tax exists; this is confirmed via Tax Foundation's 2023 local income tax primer (secondary source, https://files.taxfoundation.org/20230222173518/Local-Income-Taxes-A-Primer-2023.pdf), which does not list this state among the 16 states whose localities levy income taxes, and we found no 2026 change.

Florida rules for consultants

State income tax (2026): Florida has no state income tax on wages or self-employment income. The Florida Constitution (Art. VII, s. 5) bars a state tax on the income of natural persons who are residents or citizens, beyond amounts creditable against a similar federal or state tax.
Rideshare (TNC) driver classification and state preemption: Under Fla. Stat. 627.748(9), a TNC driver is an independent contractor if the company does not set required log-on hours, does not bar other apps or other work, and both sides agree in writing. Subsection (17) makes state law the exclusive regulator of TNCs and their drivers, preempting local rules.
Marketplace contractor law (Fla. Stat. 451.02): A worker who finds jobs through a marketplace platform app must be treated as an independent contractor, not an employee, under all state and local laws (including workers' compensation and reemployment assistance) if six conditions are met: no hours set by the platform, freedom to use other platforms, freedom to do other work, a written contractor agreement, the worker bears substantially all expenses, and the worker pays their own income taxes.

Federal rules for 2026

Solo 401(k) up to $72,000

A one-person consultancy can contribute a $24,500 employee deferral plus an employer share of about 20% of net self-employment earnings, up to $72,000 in 2026, plus an $8,000 catch-up at 50 or older ($11,250 at ages 60 to 63).

The S-corp trade-off

Electing S-corp status can cut payroll tax, but the salary you pay yourself also sets your Solo 401(k) room. Run both sides before you elect.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

A worked example

A consultant with $150,000 of net profit in 2026
Self-employment tax (sole proprietor)	$21,194
Solo 401(k) maximum	$52,381
SEP IRA maximum	$27,881
Payroll tax saved as an S-corp on a $75,000 salary	$9,719
Solo 401(k) maximum as that S-corp	$43,250

Federal figures only, before state and local taxes. Simplified: excludes the QBI deduction and the 0.9% Additional Medicare Tax. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
