Florida's Save Our Homes Cap: How Homestead Protects You from Tax Spikes

The Save Our Homes cap is the most underrated financial gift Florida gives you. File for homestead the day you close. Most buyers understand the $50,000 homestead exemption — fewer understand the compounding benefit that stacks on top of it and protects you from tax spikes for as long as you own the home.

What Save Our Homes Actually Does

Florida's Amendment 10 (1992) limits how much your assessed value can increase each year once homestead is in place. The cap is 3% or the change in the Consumer Price Index, whichever is lower. In 2025, the cap rate was 2.9% — the CPI came in slightly under the 3% ceiling.

Here's the practical effect: if you buy a home in St. Petersburg for $450,000 and the market appreciates 12% the following year, your neighbor's new purchase gets reassessed to $504,000. Your assessed value goes up no more than $13,500. Your tax bill stays manageable. Their tax bill jumps by whatever the full $54,000 increase triggers at your millage rate.

The cap doesn't kick in on day one. It takes effect the January 1 after your homestead exemption is granted. That means year one, you're exposed. Year two and every year after, you're protected.

The $50,000 Homestead Exemption

Before the cap, there's the exemption. Florida gives every primary-residence owner a $50,000 reduction in taxable assessed value. The mechanics split into two parts:

• First $25,000: reduces assessed value dollar-for-dollar across all millage rates, including school taxes.
• Second $25,000 (for assessed values between $50,001 and $75,000): applies to all millage rates except school district taxes.

For most buyers in the Tampa Bay area, the effective savings translate to several hundred dollars per year depending on your county's millage rate. Pinellas County combined millage runs around 18–22 mills depending on the city. A $50,000 reduction at 20 mills saves you $1,000 per year on its own — before the SOH cap's compounding effect.

How to File for Homestead

You apply with your county property appraiser's office, not the state. The deadline is March 1 of the tax year. You must own and occupy the home as your permanent Florida residence as of January 1 of that year.

1. Go to your county property appraiser's website. Pinellas County: pcpao.gov. Hillsborough County: hcpafl.org.
2. Complete Form DR-501 (the original homestead application) online or in person.
3. Provide proof of Florida residency as of January 1 — Florida driver's license or ID, Florida vehicle registration, and voter registration in the state all qualify.
4. Submit by March 1. Most county offices also accept applications online.
5. You only file once. The exemption renews automatically each year as long as the property remains your primary residence.

Miss the March 1 deadline and you lose that full tax year's benefit. Some counties allow a late application in limited circumstances, but don't count on it. If you close in December, get the application in before you unpack.

The Year-Two Tax Bill: Where Buyers Get Blindsided

I see this every year with out-of-state buyers. They close, they get the first tax bill — and it looks fine. Sometimes it looks great. Then the year-two bill arrives and it's $4,000, $6,000, $10,000 higher than what they expected.

Here's why it happens. Florida collects property taxes in arrears. When you close, the seller's old tax bill — capped and exempted for however many years they owned the home — is what gets pro-rated at closing. That number can be far below what the property will actually be assessed at once it's in your name.

A sale triggers a full reassessment. The county looks at what you paid and sets the new assessed value at or near that purchase price. If the previous owner bought in 2015 at $200,000 and the cap kept their assessed value at $280,000 while the market went to $480,000, their tax bill was calculated on $280,000 minus exemptions. Yours will be calculated on $480,000 minus your exemptions — at full market value.

“Always estimate your taxes based on your purchase price, not the seller's tax bill. Your lender's pre-closing estimate is the one to use for budgeting.”

What triggers a full reset: any sale of the property, a title transfer that constitutes a change in ownership, the home ceasing to be your primary Florida residence, or substantial improvements. Refinancing, adding a spouse to title in certain circumstances, and transferring to a revocable living trust typically do not trigger a reset — but verify with a real estate attorney for your specific situation.

Portability: Taking Your SOH Savings to the Next Home

This is the provision that changes how long-time Florida homeowners think about selling. If you've owned a homesteaded property for several years, your assessed value may be $100,000, $200,000, or more below market value. That gap is called your SOH benefit. When you sell and buy another Florida home, you can transfer up to $500,000 of that accumulated benefit to the new property.

The rules: you must establish your new homestead within three calendar years of abandoning the prior one. You file Form DR-501T (the portability application) along with your new homestead application — both due by March 1.

• Upsizing: if the new home's just/market value is equal to or greater than the old home's just/market value, you transfer the full SOH benefit (up to the $500,000 cap).
• Downsizing: if the new home's just/market value is less than the old home's, you transfer a proportional share of the benefit.
• The $500,000 cap: Florida voters may see HJR 211 on the November 2026 ballot, which would remove this ceiling entirely. As of April 2026 that bill has not been enacted — plan around the current $500k limit.

Portability is why many Floridians feel locked into their homes. A couple who bought in South Tampa in 2008 might have $300,000 in accumulated SOH savings. If they sell without buying another Florida home within three years, they lose that benefit permanently. If they downsize to a smaller home in St. Pete, they can port it and keep their taxes manageable.

The Senior Exemption

Homeowners who are 65 or older as of January 1 and meet an income threshold qualify for an additional $50,000 exemption on top of the standard one. For 2026, the household adjusted gross income limit is $38,686. This exemption does not apply to school district taxes and is a county-option benefit — most major Florida counties, including Pinellas and Hillsborough, have adopted it. Check with your county property appraiser to confirm availability and filing requirements.

What Homestead Does Not Cover

Investment properties, rental properties, second homes, and commercial real estate are ineligible for homestead exemption and the SOH cap. Those properties can be reassessed to full market value annually. This is one reason investment property taxes in Florida can run significantly higher than owner-occupied taxes in the same neighborhood. If you're buying a property with any intent to rent it out — including short-term rentals on Airbnb — you cannot claim homestead on that property.

Common Questions

How do I file for homestead?

File with your county property appraiser by March 1 using Form DR-501. You must own and occupy the home as your permanent Florida residence as of January 1 of that year. Most counties accept online applications — go to pcpao.gov (Pinellas) or hcpafl.org (Hillsborough).

What is portability?

Portability lets you transfer up to $500,000 of your accumulated Save Our Homes benefit to a new Florida homestead. You have three calendar years from when you abandon the prior homestead to establish the new one. File Form DR-501T alongside your new homestead application.

When does my assessed value reset?

The reset happens when there is a change in ownership — typically a sale. The county reassesses the property to full market value the following January 1. Once you've filed for homestead on the new purchase, the 3% cap starts protecting you from the year after that.

Does homestead cover investment properties?

No. Homestead exemption and the Save Our Homes cap are available only for your primary Florida residence. You can only have one homestead at a time.
