Florida Non-Homestead Assessment Cap Calculator

Florida caps how fast the assessed value of non-homestead property can rise each year. The cap is 10 percent today. Amendment 3, on the November 3, 2026 ballot, proposes lowering it to 5 percent. This tool shows what that difference looks like on a second home, rental, or investment property over time.

Status as of August 2026: Amendment 3 (CS/HJR 1F) is a proposed constitutional amendment, not current law. It appears on the November 3, 2026 general election ballot and needs 60 percent voter approval to pass. If approved, the 5 percent cap would take effect January 1, 2027 and would first show up on August 2027 TRIM notices and the tax bills mailed in November 2027. The ballot language has been subject to court-ordered revision, so confirm current status with your county property appraiser or the Florida Division of Elections before relying on it.

Property assumptions

Use assessed value from your TRIM notice, not purchase price or market value.
One mill equals $1 of tax per $1,000 of taxable value. Exclude school millage, the cap does not apply to school taxes.

Educational scenario tool only. This does not calculate an official tax bill, determine eligibility, or account for every exemption, reassessment event, ownership change, special assessment, taxing district, school tax, or portability rule. A lower assessment cap slows assessed-value growth, it does not by itself lower a tax bill, because millage rates are set annually by local taxing authorities. Amendment 3 is proposed and is not current law unless approved by voters and implemented. Confirm all figures with the applicable county property appraiser and tax collector, and consult a CPA or attorney for tax advice. This is not a commitment to lend or a quote of loan terms.
Common Questions

Florida Assessment Cap Questions, Answered

What the cap does, what Amendment 3 would change, and why it matters when you finance.

What is Florida Amendment 3?

Amendment 3 (CS/HJR 1F) is a proposed amendment to the Florida Constitution on the November 3, 2026 general election ballot. Among other property tax changes, it would lower the annual assessment growth cap on non-homestead property from 10 percent to 5 percent. Like all Florida constitutional amendments, it requires 60 percent voter approval to pass. If approved, this provision would take effect January 1, 2027 and would first appear on August 2027 TRIM notices and the tax bills mailed in November 2027. Verify current status before relying on this, since the ballot language has been subject to litigation.

What is the non-homestead assessment cap?

Florida limits how much the assessed value of non-homestead property can rise each year, regardless of how fast market value climbs. Non-homestead means property that is not your primary residence with a homestead exemption, so second homes, vacation properties, rental and investment property, and certain non-residential property. The cap is currently 10 percent per year. It applies to non-school taxes only.

Does the cap apply to school taxes?

No. This is the detail most people miss. The non-homestead assessment cap applies only to the non-school portion of your tax bill. School district taxes continue to be calculated on full just or market value with no cap. That is why this calculator asks for your non-school millage rate specifically, and why the result is not your total tax bill.

Would a 5 percent cap lower my property taxes?

Not necessarily, and this is an important distinction. The cap limits how fast your assessed value grows, not what you pay. Your actual bill is assessed value multiplied by the millage rates set each year by your county, city, and other taxing authorities. If those authorities raise millage rates, your bill can still rise even with a slower-growing assessed value. What a lower cap does reliably is reduce how quickly the taxable value climbs in a fast appreciating market.

When does the assessment cap reset?

The cap protection resets when the property changes ownership or control. On a qualifying change, the property is reassessed at full just value the following January 1, and the cap starts over from that new base. This is why a buyer cannot assume the seller's capped assessed value carries over. Budgeting from the seller's current tax bill is one of the most common and most expensive mistakes buyers make on Florida investment property.

Why does this matter for a mortgage?

Property taxes are escrowed into your monthly payment, so an assessment reset after purchase directly raises PITI. On coastal Florida investment property, where a reset can move assessed value substantially and insurance is already heavy, an underwriter using the seller's old tax figure produces a payment that does not survive the first tax bill. Financing on non-homestead coastal property should be modeled on post-reset taxes plus realistic wind and flood insurance, not the current owner's numbers.

Is this calculator my actual tax bill?

No. It is an educational scenario tool. It does not calculate an official tax bill, determine eligibility, or account for every exemption, reassessment event, ownership change, special assessment, taxing district, school tax, or portability rule. Confirm all figures with your county property appraiser and tax collector, and with a CPA or attorney for tax advice.

The assessment resets when the property changes hands. Financing modeled on the seller's old tax bill breaks at the first bill. Send the address and get the real payment.
