Calculators
Miami-Dade Property Tax Calculator
I built this calculator for buyers pricing a purchase in southwest Miami-Dade. Enter a price and it estimates the first-year property tax bill across the eight neighborhoods I cover, using the 2025-26 adopted millage rates verified against the Miami-Dade Property Appraiser's chart.
Rates last verified August 2026 against the Miami-Dade Property Appraiser's 2025-26 adopted millage chart.
How this works
Enter a purchase price and the calculator estimates an assessed value at 85% of it, because Florida law (F.S. 193.011(8)) requires just value to be measured net of the usual costs of sale, and in practice that lands near 85% of a recent sale price. If the home will be your primary residence, the homestead toggle subtracts the 2026 exemption of $51,411 before any tax math runs.
The table then multiplies that taxable value by the 2025-26 combined millage for each area, from 16.9317 mills in unincorporated Miami-Dade up to 19.9878 mills in Coconut Grove, which sits inside the City of Miami. On $1,000,000 of taxable value the spread between those two rates is about $3,056 a year, which is why the same budget carries differently from one neighborhood to the next.
The calculator is free and runs entirely in your browser, and nothing you type is sent anywhere or stored. If you want to see what actually sits inside a combined millage rate, the companion article below breaks the stack down levy by levy.
