What happens to property taxes when you buy a home in Unincorporated Pinellas County, FL

It depends on the tax district. A residential parcel in Unincorporated Pinellas County can fall in 23 of them, and the 2025 certified rates run from 15.3229 mills (AA, County) to 22.9198 mills (LFPW, Lealman Fire). The property appraiser's record for the address names the district. The full table is on this page.

Because the number on the listing was computed under a cap that ends when you buy. Save Our Homes limits a homestead assessment to the lesser of 3% or CPI a year while one owner holds it (s. 193.155(1), Fla. Stat.), so a long-held home can sit far below what it is worth. Homestead property is assessed at just value as of January 1 of the year following a change of ownership. A change of ownership means any sale, foreclosure, or transfer of legal or beneficial title in equity. (s. 193.155(3)(a), Fla. Stat.) Your bill is then computed from just value, not from the seller's capped figure.

March 1. An exemption application must be filed with the county property appraiser on or before March 1. Failure to apply by March 1 constitutes a waiver of the exemption privilege for that year. (s. 196.011(1)(a), Fla. Stat.) An application filed without a required social security number is incomplete and must be cured by April 1 (s. 196.011(1)(b), Fla. Stat.). If you see a homestead exemption on the parcel record after you buy, that is the seller's exemption for the current year; it does not transfer to you.

As an arithmetic illustration on the published rate, not a statistic about local prices: if the assessment resets to $450,000 of just value and you file the homestead exemption on time, taxable value is $425,000 for the school levy and $398,589 for the rest, and at 15.3229 mills in district AA the annual bill computes to $6,274. With no exemption — an investor buyer, or an owner-occupant who missed March 1 — the same home computes to $6,895.

On a home that resets to $450,000 of just value in district AA, $622 a year. The exemption is $25,000 against all levies plus a further $26,411 against the non-school levies only, and the second amount applies only to assessed value above $50,000 (s. 196.031(1)(a)-(b), Fla. Stat.). The $26,411 figure is the 2026 amount, the latest the Department of Revenue has published; it is indexed to CPI and changes each year.

Yes, and it reaches further than most buyers expect. Non-homestead residential property has its own 10% annual cap for 2026, and that cap applies only to the non-school levies — the school portion is assessed at just value every year (s. 193.1554(2)-(3), Fla. Stat.). The cap also ends on a change of ownership or control, and that includes the cumulative transfer of control or of more than half the ownership of the entity that held the property (s. 193.1554(5), Fla. Stat.). Selling the LLC rather than the deed does not avoid it.

If you held a Florida homestead exemption as of January 1 in any of the three immediately preceding years, you may transfer up to $500,000 of accumulated Save Our Homes benefit to the new home (s. 193.155(8), Fla. Stat.). It is claimed as an attachment to the homestead application, so it rides the same March 1 deadline, and refunds of tax may not be made for previous years. Portability is specific to your history, so the figures on this page show the reset as the statutory default and do not assume it.
