Miami-Dade County Library District
An estimate of how Amendment 3's larger homestead exemption could change ad valorem property tax revenue for the Miami-Dade County Library District, based on 2026 property values and the final 2026 tax rate of 0.2812 mills.
These are estimates, not forecasts. They hold today's values and tax rate constant to show the effect of the new exemption by itself. Property values, the number of homesteads and tax rates will all change. Property taxes are also not the only source of revenue for the Miami-Dade County Library District.

Estimated revenue by year
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 tax rate stays at its final 2026 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.

What drives the estimate
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. Within the district, homesteads make up 28.8% of taxable value in 2026.
Property taxes are one of several revenue sources
Taxing authorities like the Miami-Dade County Library District can also receive money from other sources, such as state and federal grants, fees, partnerships and contributions. The Miami-Dade County Library District's adopted budget shows its full set of revenue sources and how much each provides.
Miami-Dade County government, the cities and towns, the The Children's Trust, the water management district and the School Board levy their own property taxes and are not included on this page.
Limitations of these estimates
- Values will change. Market values, new construction and demolitions will all change taxable value. Here, property without a homestead exemption stays at its 2026 value, and homestead assessed values either stay flat or rise by up to 3% a year, but not above each home's 2026 just value. Homes already assessed at their just value don't rise at all, and just values will themselves change with the market. The Save Our Homes cap for 2026 was 2.7%.
- The number of homesteads will change. When a homestead sells, its assessed value resets to market value for the new owner. New owners may or may not apply for a homestead exemption. Owners who were not Florida residents on Dec. 31, 2026, receive a $50,000 non-school exemption instead of the larger amounts. None of these changes are modeled.
- Tax rates may change. The Miami-Dade County Library District's governing board sets its millage rate each year. These estimates hold the final 2026 rate of 0.2812 mills constant to show the effect of the exemption alone.
- Other parts of Amendment 3 are not modeled, including the new 5% annual cap on non-school assessment increases for property without a homestead exemption.
- Discounts and unpaid taxes. Property owners who pay early get a discount under section 197.162, Florida Statutes: 4% in November, 3% in December, 2% in January and 1% in February, with no discount in March. Some taxes are paid late or not at all, and value adjustment board decisions can lower a property's value after the roll is certified. Section 200.065, Florida Statutes, requires taxing authorities to use at least 95% of their taxable value when setting tax rates, and the Florida Department of Revenue's 2026 TRIM Compliance Workbook says each millage rate must include at least 95% of ad valorem proceeds in the budget. This page shows both the gross levy and 95% of it, called the budget basis. Actual collections vary from year to year and can be above or below 95%.
- Real property only. These figures cover land and buildings on the tax roll. Taxes on tangible personal property, such as business equipment, and on centrally assessed property, such as railroads, are not included. That property has no homestead exemption, so including it would add revenue that Amendment 3 does not change.
- Collection and assessment costs are not subtracted. Fees or commissions that may be paid to the tax collector or property appraiser are not included.
- Operating millage only. Any voter-approved debt service millage is not included.
- This page does not predict budgets, services or how the Miami-Dade County Library District may respond. For official figures, see its budget documents and the Miami-Dade County Property Appraiser.
Sources and method
Property values and exemptions: The Miami-Dade County Property Appraiser's 2026 final tax roll, as published by the Florida Department of Revenue. Tax rates: the Property Appraiser's 2026 adopted millage 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 0.2812 mills. The budget basis is 95% of the gross levy.
