As with the cities and towns, the size of the change depends mostly on how much of the taxable value comes from homesteads. Property without a homestead exemption, such as rentals, businesses, second homes and vacant land, keeps its taxable value under the amendment.
Countywide, homesteads make up 46.7% of the taxable value for the countywide levies in 2026. Within the fire rescue MSTU area, they make up 49.2%, so the estimated percentage change for that levy is larger. Among the five cities and towns that levy a property tax, the homestead share ranges from 12.0% to 66.8%.
The table below shows where the change in the countywide taxable value comes from. Unincorporated Martin County has 73.9% of the county's taxable value and accounts for an estimated 91.4% of the change. The Town of Jupiter Island has 11.6% of the county's taxable value and accounts for an estimated −0.8% of the change.

Estimates use homestead assessed values rising by up to 3% a year, capped at just value. Areas are based on each parcel's tax district.
Florida counties also receive money from other sources. Depending on the county, these can include state revenue sharing, the local government half-cent sales tax, local option sales and fuel taxes, communications services taxes, non-ad valorem assessments, franchise fees, charges for services, and state and federal grants. The mix differs from county to county. Martin County's adopted budget shows its full set of revenue sources and how much each provides.
The Children's Services Council of Martin County, the Florida Inland Navigation District, the water management district and the School Board levy their own property taxes. They are separate taxing authorities and are not included on this page.
Property values and exemptions: The Martin County Property Appraiser's 2026 final tax roll, as published by the Florida Department of Revenue. Tax rates: the Property Appraiser's 2026 final millage codes and tax rates. Parcel tax districts: the millage codes on the same tax roll.
For each homestead, the estimated taxable value is its assessed value minus the new homestead exemption ($150,000 in 2027, $250,000 in 2028) and any other exemptions, but not less than zero. The gross levy is total taxable value times the millage rate, for the parcels where each levy applies. The budget basis is 95% of the gross levy.
