Homestead assessed values rise by up to 3% a year, the most Save Our Homes allows, but never above each home's 2026 just (market) value. All other property stays at its 2026 taxable value. The city's tax rate stays at its 2025 level. The gross levy is taxable value times the tax rate. The budget basis is 95% of the gross levy, which allows for early-payment discounts and unpaid taxes; see the limitations below.

Of Clay County's four cities and towns, the City of Keystone Heights has the largest estimated percentage change in city ad valorem revenue by 2028. The estimated change is −35.8%. Two things determine its size.
How much of the city's taxable value comes from homesteads. The amendment changes the exemption only for homesteads. Property without a homestead exemption, such as rentals, businesses, second homes and vacant land, keeps its taxable value. In the City of Keystone Heights, homesteads make up 39.2% of taxable value in 2026, the second-highest share of the four. Among the four, the share ranges from 10.5% to 48.2%.
How much of that homestead value the new exemption removes. Because the exemption is a flat dollar amount, it removes a larger share of value from homes with lower assessed values. The median homestead in the City of Keystone Heights has an assessed value of $137,330, the second-lowest of the four. By 2028, the new exemption is estimated to remove 91.2% of the city's homestead taxable value. Among the four, this ranges from 72.6% to 91.2%.
Across the county, places where homesteads make up a larger share of taxable value generally have larger estimated percentage changes. Home values also play a part. Keystone Heights has the lowest median homestead assessed value; the exemption removes 91.2% of its homestead taxable value, and its estimated percentage change is the largest of the four.
| City or town | Homestead share of taxable value, 2026 | Median homestead assessed value | Homestead taxable value removed by 2028 | Estimated revenue change by 2028 |
|---|---|---|---|---|
| City of Green Cove Springs | 48.2% | $216,790 | 72.6% | −34.9% |
| City of Keystone Heights | 39.2% | $137,330 | 91.2% | −35.8% |
| Town of Orange Park | 32.0% | $169,816 | 73.1% | −23.3% |
| Town of Penney Farms | 10.5% | $107,900 | 82.2% | −8.7% |
Sorted by homestead share of taxable value. Estimates use homestead assessed values rising by up to 3% a year, capped at just value and the 2025 municipal tax rates.
| Year | Homestead exemption | Homesteads with $0 city taxable value | Share of homesteads | Median city tax per homestead | Homestead share of city taxable value |
|---|---|---|---|---|---|
| 2026 | up to $51,411 | 19 | 4.8% | $299 | 39.2% |
| 2027 (estimate) | $150,000 | 225 | 57.1% | $0 | 17.3% |
| 2028 (estimate) | $250,000 | 351 | 89.1% | $0 | 5.4% |
Estimates use homestead assessed values rising by up to 3% a year, capped at just value. Median city tax counts only the city's own millage, not county, school or other taxes.
Florida cities and towns also receive money from other sources. Depending on the place, these can include state revenue sharing, the local government half-cent sales tax, local option sales and fuel taxes, public service taxes on utilities, the communications services tax, franchise fees, charges for services such as utilities and permits, and state and federal grants. The mix differs from place to place. The City of Keystone Heights' adopted budget shows its full set of revenue sources and how much each provides.
Property in the city also pays Clay County government's fire control MSTU and law enforcement MSTU. That money goes to the county, not the city, and is not included in these figures.

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 the city's total taxable value times 3.6073 mills. The budget basis is 95% of the gross levy, following section 200.065, Florida Statutes, and the Department of Revenue's 2026 TRIM Compliance Workbook. Early-payment discounts: section 197.162, Florida Statutes.
