Okaloosa County Property Tax Calculator

Where property data comes from

Address and parcel lookup uses the Okaloosa County Property Appraiser's public ArcGIS REST service:

gis.myokaloosa.com/arcgis/rest/services/BaseMap_Layers/MapServer/111

Optional enrichment may also read the Property Appraiser's per-parcel detail page and AssessmentInformation layer for district names and overlay detection. We are not affiliated with the Property Appraiser or Tax Collector.

Where millage rates come from

Millage rates come from the Okaloosa County Property Appraiser's 2025 Final Millage publication — the same certified rates that appear on your TRIM notice. We keep those line items in this site's data files and check them against real 2025 TRIM notices. These are the final adopted 2025 rates — the ones your 2025 tax bill was calculated from — not the prior-year rates.

Your tax notice also carries flat charges that are not based on your home's value — a stormwater fee, a solid-waste fee, or a street-lighting assessment, for example. These are called non-ad valorem assessments. We do not include them: they are set parcel by parcel and are not published in the county data we can read.

How calculations work

The calculator applies Florida homestead exemption rules to each millage line: $25,000 on school lines (unchanged in every scenario) and a scenario-specific amount on non-school lines. It models three Amendment 3 homestead exemption scenarios — current law plus Phase 1 and Phase 2.

How we check accuracy

We test the calculator line by line against real Okaloosa tax notices and confirm each rate and each line total matches. Separately, a nightly automated check confirms the county's property lookup is still responding — that catches outages and breaking schema changes, not subtle data errors. If your notice and our estimate disagree, email info@saveourhomescalculator.com with your parcel number.

Countywide fiscal impact (computed)

We compute projected ad valorem revenue reductions for Okaloosa County taxing districts by applying the Amendment 3 exemption phases to currently homesteaded parcels in the Florida Department of Revenue's certified 2025 NAL tax roll, using 2025 certified millage rates. Each parcel's reduction is capped at the value it is actually taxed on, since a taxing authority cannot lose more ad valorem than it levied.

• Phase 1 ($150,000 exemption): approximately 26.5 million in reduced ad valorem revenue (41.0% reduction on current homestead ad valorem)
• Phase 2 ($250,000 exemption): about $42.4 million a year less — a 65.6% reduction in what homesteaded properties pay today in non-school property tax. School taxes are not affected, and non-homestead property is not included in this figure.

These figures use the exemption levels Amendment 3 sets. They will be cross-checked against the County's own fiscal impact analysis when an Amendment 3-specific version is published. Methodology and district-level detail are available on request: info@saveourhomescalculator.com.

Renter and non-homestead sources

The renter and non-homestead path quotes the ballot summary's assessment-cap provision (10% to 5%, non-school) and the Florida Revenue Estimating Conference's statewide projection as recorded in this site's status file. It does not attribute a cost-shift projection to any outside analyst. What it says instead is arithmetic and conditional: the larger exemption reaches homesteaded property only, and if an authority keeps spending the same with less property tax revenue, the difference comes from somewhere else. Each elected board decides whether to cut, raise its rate, or use reserves.
