Taxes in Port St. Lucie
Florida has no state income tax, which is the headline tax fact for anyone moving to Port St. Lucie from a state that does. Property taxes are the other side of that ledger: St. Lucie County's effective property tax rate runs above both the state and national medians, even as the city's own municipal millage rate has been falling for over a decade.

Learn moreNo state income tax
Florida levies no state personal income tax, a real and simple savings for anyone relocating from a state with a meaningful income tax rate (discussed with specific comparison rates on the Moving page). This is a state-level fact, not specific to Port St. Lucie, but it is one of the most-cited reasons people give for relocating here.
Property tax: falling millage rate, rising bills
Port St. Lucie's city (municipal) millage rate was cut for an 11th consecutive year, from 4.9750 mills in FY2025-26 to 4.8750 mills in FY2026-27, per Hometown News Treasure Coast -- the city cites this as giving it the third-lowest municipal tax rate among Florida's 20 largest cities and a roughly $2,000 cumulative homeowner savings since 2016. But a lower millage rate is not the whole property-tax picture: WFLX reported that St. Lucie County property taxes are rising overall despite the lower millage rate, because countywide taxable property values have more than doubled -- a real and disclosed tension between the city's rate-cut messaging and residents' actual bills.
Effective rate: sources disagree on the exact number
Ownwell's aggregate data puts St. Lucie County's median effective property tax rate at 1.31% (median bill about $3,869), above both the national median (about 1.02%) and the Florida median (about 1.10%); a separate aggregator cited 1.23% for the same geography, a real disclosed gap rather than a single settled figure. Effective rates vary meaningfully by location within the county depending on school-district and special-assessment overlays.
Sales tax
St. Lucie County's combined sales tax rate is 7% -- Florida's 6.0% state rate plus the county's 1.0% surtax, per Avalara's 2026 rate data. No additional city-level sales tax applies within Port St. Lucie.
Homestead exemption and Save Our Homes
Florida homeowners who make a property their primary residence and file with the St. Lucie County Property Appraiser by March 1 of the following tax year qualify for the homestead exemption (up to $51,411 off taxable assessed value in 2026) and the Save Our Homes cap, which limits future annual assessed-value increases to 3% or the CPI, whichever is lower -- see the Buying a Home page for the filing mechanics.
Key takeaways
- Florida has no state income tax -- the single biggest tax draw for movers from higher-tax states.
- St. Lucie County's effective property tax rate is estimated at 1.31% (Ownwell) or 1.23% (a second aggregator), above both the Florida median (~1.10%) and national median (~1.02%) either way.
- Port St. Lucie's city millage rate has fallen for 11 straight years (to 4.8750 mills for FY2026-27), but countywide tax bills are still rising overall because taxable property values have more than doubled -- a falling rate does not necessarily mean a falling bill.
- Combined sales tax is 7% (6.0% state + 1.0% county surtax).
