The Property Tax You See Online Isn’t the Tax You’ll Pay When You Buy in Tampa

Quick answer: The tax amount you see on the Hillsborough County Property Appraiser’s website usually reflects the seller’s situation, including their homestead exemption and the cap on how fast their assessed value can rise. When you buy, that cap ends, the home is reassessed at full market value, and you have to apply for your own homestead exemption. Your bill can be quite different from the seller’s.

I am a real estate agent, not a tax advisor, so treat this as a guide to what to ask and where to look, and confirm numbers with the property appraiser or a tax professional. Here is how it works.

Why does the appraiser’s website show a lower number?

Florida’s Save Our Homes cap limits how much the assessed value of a homesteaded property can go up each year to 3% or the change in the Consumer Price Index, whichever is lower. A long-time owner’s assessed value can fall well below the home’s market value, and the tax they pay is based on that lower number.

What happens when I buy?

A sale is a change of ownership. The Hillsborough County Property Appraiser says the home is reassessed at full market value on January 1 of the following year, and the cap and the exemption both end on that date. The new owner has to apply for and receive their own homestead exemption.

Here is a made-up example to show the idea, not a real Tampa number. If a seller’s capped assessed value is $350,000 and the home’s market value is $600,000, your starting point is based on the market value, not on the seller’s $350,000.

Do I get homestead automatically?

No. You apply, and the deadline is March 1. The Property Appraiser’s office offers online filing. Your assessed value is set at full market value as of January 1 of the year the exemption is first granted, and the cap starts to apply the year after.

How much does the homestead exemption save?

According to the Florida Department of Revenue, the first $25,000 of assessed value is exempt from all property taxes, including school taxes. A second $25,000, on assessed value between $50,000 and $75,000, is exempt from non-school taxes only. If you qualify, the second one is applied automatically. These are the amounts through 2026. Amendment 3 raises the non-school exemption starting in 2027, as described below.

How do I estimate what I will actually pay?

1. Find the home’s market value, which the Property Appraiser sets as of January 1.
2. Subtract your exemptions to get the taxable value.
3. Multiply by the total millage rate for that address and divide by 1,000. One mill is $1 for each $1,000 of taxable value. Each taxing authority, such as the county, city, or school board, sets its own rate. The Property Appraiser does not.
4. Add any non-ad valorem assessments, which are set separately by taxing authorities.

The Property Appraiser also has a Tax Estimator tool. Use it, and ask your lender to include a realistic tax estimate in your payment, not the seller’s number.

What does Amendment 3 change?

Update, November 4, 2026: Florida voters approved Amendment 3 on November 3. The News Service of Florida reported 62% support, and the measure needed at least 60%. It takes effect January 1, 2027. For non-school property taxes, the homestead exemption rises to the first $150,000 of assessed value in 2027 and the first $250,000 in 2028, with inflation adjustments after that. The amendment also lowers the annual cap on assessment increases for non-homestead property, such as rentals and commercial property, from 10% to 5%. People who move to Florida starting in 2027 will face a five-year transition before they qualify for the higher exemption.

The main point of this post stays the same: do not rely on the seller’s tax bill to predict yours. Your bill will depend on your home’s value, your exemptions, and local millage rates, so check with the Property Appraiser. These results were reported on election night, so confirm the final details with the Property Appraiser’s office.

What if I am moving from another Florida homestead?

You may be able to carry over part of your accumulated Save Our Homes savings to your new home. That is called portability, and it has its own application and deadline. Ask the Property Appraiser’s office whether you qualify.
