Florida limits how fast the taxable value of a home can climb each year, and the limit depends on how you use the home. A second home, rental, or investment property is capped at 10% a year. A homesteaded primary residence is capped at 3%. Here is how the 10% cap works, the places it does nothing, and the reset at sale that catches buyers off guard.
A non-homestead property is anything that isn't your homesteaded primary residence: a second home, a vacation place, a long-term or short-term rental, raw investment property, most commercial buildings. Florida caps how fast the assessed value of those properties can climb. Florida put that cap in place in 2008, and it took effect on the 2009 tax roll. The number is 10% a year.
Assessed value is the figure your taxes are actually calculated on, and it isn't the same as market value. In a hot market, market value can jump 15% or 20% in a year, but the cap says the taxable assessment on a non-homestead property can only rise 10%. The gap between what the home is worth and what it's taxed on is the whole benefit of the cap. It builds slowly, and it belongs to you only while you own the property.
Save Our Homes is the cap on a homesteaded primary residence. It limits assessed value growth to 3% a year, or the change in inflation if that's lower, and it applies to every tax on the bill, school taxes included. A homestead also gets the homestead exemption, which takes up to roughly $50,000 off the taxable value.
Same idea, much tighter limit, different property. If you live in the home full time and file for homestead, you get the 3% cap. If it's a coastal second home or a rental, the 10% cap is the one that governs your assessment growth. That gap is one of the real numbers to weigh if you're deciding whether a Florida home will be your full-time residence. Our homestead timeline for snowbirds covers the dates and paperwork.
Drop in a price, an appreciation assumption, and your county's non-school millage. The tool shows year by year how a second home (10% cap) and a homestead (3% cap) pull apart, and tells you honestly when the gap is small.
Here's the part most coverage skips. A cap only does something when the market would otherwise outrun it. If your property's market value rises 4% a year, the 10% cap never kicks in, because assessed value is just tracking the market. The cap isn't binding.
The gap opens up only when appreciation runs above the cap rate. At 12% or 15% a year, market value pulls away from the capped assessment, and because assessment growth compounds, the gap widens every year you hold. In a flat market the cap is a rounding error. That's why the appreciation assumption is the most important input when you model this.
The non-homestead cap doesn't touch the school district portion of your bill. School levies are figured on full market value every year, cap or no cap. Only the non-school part of your millage, county, city, and special districts, uses the capped assessed value. Any estimate that applies the cap to your total millage overstates the benefit, which is why our calculator asks for non-school millage only.
It resets. When a property changes hands, the assessed value goes back to full market value the next January 1, and the cap starts over from there. A new buyer never inherits the seller's capped number.
That's the trap. The $9,000 tax bill a seller has been paying after years of capped growth isn't the bill you'll pay. A long-held Keys house can reassess to two or three times the seller's number in year one. Underwriters use the projected new tax figure, not the seller's, which is how a deal can look fine in a spreadsheet and then fail on debt-to-income. Budget from the post-sale assessment, not the listing sheet.
Treat the cap as one line in a bigger picture, not the reason to buy. Coastal carrying costs are driven far more by insurance and the loan structure than by the assessment cap. The right move is to model the tax reset alongside the real payment, the flood and wind premiums, and the rate, so you're deciding on the whole number. That's what I do on coastal files: run the tax scenario, price the insurance, and put the true monthly cost in front of you before you write the offer.
What is Florida's non-homestead assessment cap?
A limit on how much the assessed value of a non-homestead property can rise each year. Florida adopted a 10% cap in 2008, effective for the 2009 tax roll. It covers second homes, rentals, vacation homes, and most commercial and investment property. It does not apply to the school district portion of the tax bill.
Is the non-homestead cap the same as Save Our Homes?
No. Save Our Homes caps a homesteaded primary residence at 3% a year or the change in inflation, whichever is lower, and it applies to all taxes including school taxes. The non-homestead cap is 10% a year and applies to non-school taxes only.
Does the non-homestead cap apply to school taxes?
No. School district taxes are calculated on full market value every year. The cap only limits assessed value growth for county, city, and special district taxes.
When does the non-homestead cap reset?
When the property changes ownership, and in some cases after certain improvements or a change in use. The assessed value goes back to full market value the next January 1 and the cap starts over. A buyer never inherits the seller's capped value.
Does the 10% cap lower my property taxes?
It limits how fast assessed value grows, not what you pay. Your bill is taxable value times the millage rates set each year by local taxing authorities, so a bill can still rise. The cap only makes a difference when market values rise faster than 10% a year.
Why does the cap matter for a mortgage?
Property taxes are escrowed into your monthly payment. After a purchase the assessment resets to market value, so the tax line in your payment is based on the new assessment, not the seller's bill. That number affects your debt-to-income ratio and what you qualify for.
