Treasure Coast Property Taxes: County-by-County Breakdown

Property tax rates in Brevard, Indian River, St. Lucie, and Martin counties — homestead exemptions, Save Our Homes cap, and how Florida compares to other states.

Florida has no state income tax, but property taxes vary meaningfully across the four Treasure Coast counties. New construction buyers should understand both the base millage rates and how the homestead exemption and Save Our Homes cap will impact their long-term costs.

Approximate millage rates by county

Combined county + city + school millage (approximate)

County-by-county millage rates (approximate)

Brevard: ~12–15 mills depending on city. Indian River: ~14–17 mills. St. Lucie: ~18–22 mills (highest on the Treasure Coast, partly offset by lower home prices). Martin: ~14–17 mills.

Millage = $1 of tax per $1,000 of assessed value. Always verify with the county property appraiser.

Homestead exemption

Florida residents who occupy their home as a primary residence by January 1 receive a $50,000 homestead exemption ($25,000 applies to all taxes; the second $25,000 applies to non-school taxes). File with the county property appraiser by March 1.

Save Our Homes cap

Once homesteaded, your assessed value can rise no more than 3% per year (or CPI, whichever is lower) regardless of market value. New homestead applies the cap on the second year — your first full tax year is based on the just/market value at January 1.

Homestead portability — transfer your Save Our Homes savings

If you already own a homesteaded Florida property and you're moving within Florida, portability lets you carry the gap between your old home's just (market) value and its capped assessed value over to your next homestead — up to $500,000 of benefit.

The window: you must establish the new homestead within three tax years of abandoning the prior one (the statute counts tax years, not calendar years, so plan the January 1 ownership and occupancy date carefully).

Upsizing (new home worth more than the old): you transfer the full Save Our Homes differential dollar-for-dollar, capped at $500,000.

Downsizing (new home worth less than or equal to the old): you transfer a proportional share, calculated as new just value × (old assessed value ÷ old just value).

Split households: spouses who previously shared a homestead can split the benefit when establishing separate homesteads, each claiming up to $500,000.

How to file: submit Form DR-501T ("Transfer of Homestead Assessment Difference") alongside your standard DR-501 homestead application with the new county's property appraiser by March 1. Out-of-state moves do not qualify — portability is Florida-to-Florida only.

Why the first tax bill on new construction can shock

Builders often quote taxes based on the LOT-only assessment. Once your home is built and assessed, your tax bill can triple year-two. Always budget using the post-construction estimate from the property appraiser, not the builder's pro-forma.

Frequently Asked Questions

Which Treasure Coast county has the lowest property taxes?

Brevard tends to have the lowest effective rate, followed by Indian River and Martin. St. Lucie has higher millage rates but lower home prices on average.

Can I transfer my homestead from another Florida county?

Yes — Florida's portability rule lets you carry up to $500,000 of your Save Our Homes savings to a new homestead anywhere in Florida. You have three tax years from abandoning your prior homestead to establish the new one, and you file Form DR-501T alongside your standard homestead application by March 1.

Does portability help if I'm moving from out of state?

No — portability only applies to Florida-to-Florida moves. Buyers relocating from another state start fresh with a new $50,000 homestead exemption and a new Save Our Homes baseline once they establish Florida residency and file by March 1.

How does the Save Our Homes 3% cap work in Vero Beach and Indian River County?

Once you establish homestead on a Vero Beach or Indian River County property, your assessed value can rise no more than 3% per year (or CPI, whichever is lower), even if market values jump 10–20%. The cap kicks in your second tax year — your first full year is assessed at January 1 just/market value.

How much homestead portability can I bring to a new Vero Beach home?

Up to $500,000 of Save Our Homes savings if you're upsizing from another Florida homestead. File Form DR-501T with the Indian River County Property Appraiser by March 1 of the year after you establish residency, alongside your standard DR-501 homestead application.

Why is my first property tax bill on a new construction home so much higher than the builder estimated?

Builders typically quote taxes based on the lot-only assessment from before the home was built. Once the finished home is on the tax roll the following January 1, your assessed value (and bill) often doubles or triples. Always budget using the property appraiser's post-construction estimate, not the builder's pro-forma.
