Miami-Dade County
property tax, explained.

The Property Appraiser’s value guide distinguishes market, assessed and taxable values. Assessment limits and exemptions affect these stages differently, and not every benefit applies to school taxes.

Make one row per taxing authority with its taxable value, millage and resulting tax. Only combine rates when their taxable bases are identical. Keep the folio number and year with your worksheet so a nearby property or different year does not slip into the comparison.

The Save Our Homes explanation describes why taxes can change after a purchase. A protected assessment on a long-held home is not a promise of the buyer’s next bill.

Use the official tax estimator for a purchase scenario and read its assumptions. Its explanation says it uses previous-year adopted millage, so the estimate is a planning figure rather than a confirmed future bill. Record the purchase scenario and rate year alongside the result.

The portability guidance explains the application and approval process. The worked examples show why the calculation can differ when moving to a less valuable home or sharing a benefit among owners.

Keep the old homestead record, ownership shares and new property details available when reviewing eligibility. Enter the resulting approved taxable value here; do not subtract a guessed portability amount from a record that already includes it.

The TRIM non-ad valorem guidance explains the separately listed benefit assessments. They belong in the final budget but are outside this one-authority millage calculation.

Compare the proposed notice and final bill by authority, checking whether rates or values changed. Keep non-ad valorem charges on separate rows. For a question about a particular assessment, use its issuing authority’s contact information rather than assuming the Property Appraiser controls every charge.
