Florida Save Our Homes cap calculator

The answer up front: homestead a Florida home and its assessed value can rise at most 3 percent a year (or CPI, if lower — Fla. Stat. §193.155) no matter what the market does. Start at $300,000 with the market growing 6 percent a year, and after 10 years the market value is $537,254 but your taxable assessed value is held to $403,175 — an untaxed gap of $134,079, worth about $2,011 a year at a typical 15-mill rate.

Reading the projection honestly

• The cap uses 3 percent as its ceiling — in low-inflation years the actual cap is the CPI change, so your real assessed growth can be slower than this projection. This page shows the statutory maximum path.
• Assessed value never exceeds market: if the market grows slower than the cap, assessed simply tracks market and the gap is zero — the calculator models that.
• The gap compounds quietly: the longer you hold the homestead, the bigger the wedge between what your home is worth and what you're taxed on — often worth more over time than the homestead exemption itself.

Moving within Florida? The portability calculator computes how much of this benefit you can carry. Buying a home with a big existing gap? It resets at sale — the buyer estimator shows your real bill, and the homestead calculator the exemptions that stack on top.

Quick answers

What is the Save Our Homes cap?

Once a Florida home is homesteaded, its ASSESSED value can rise at most 3 percent a year — or the CPI change, whichever is lower (Fla. Stat. §193.155) — no matter how fast market value climbs. The growing gap between market and assessed value is never taxed while you keep the homestead.

Does the cap transfer when I move?

Up to $500,000 of the accumulated benefit is portable to a new Florida homestead if you re-establish within three tax years — the portability calculator on this site computes exactly what you can carry.

What about rental and second homes?

Non-homestead property has its own 10 percent assessment cap (§193.1554), which does not apply to school levies. November 2026's Amendment 3 would tighten that cap to 5 percent if it passes.

What happens to the cap when a home sells?

It dies at closing — the buyer's assessed value resets to market as of the next January 1 (§193.155(3)). That's why a listing's current tax bill is the seller's bill, not the buyer's — the buyer estimator models the reset.
