Why Did My Property Taxes Jump After I Bought a House in Jacksonville?

It's one of the most common surprises for new Jacksonville homeowners. You looked up the home's property taxes before you bought it. Then your first bill arrives, and it's much higher.

Nothing went wrong. It's how Florida property taxes are designed. Once you understand it, you can plan for it and make sure you're getting every dollar of savings you're entitled to.

The previous owner had a cap. You don't. Yet.

Florida has a rule called Save Our Homes. Once an owner has a homestead exemption, the assessed value of the home can only go up by 3% or the rate of inflation, whichever is lower, each year.

If someone has lived in a home for ten years, their assessed value may be far below what the home is actually worth today. Their tax bill reflects that lower number.

When the home sells, the cap goes away. On January 1 of the year after the sale, the home is reassessed at its full market value. Your tax bill is then based on that new value, not the old capped one.

The takeaway: don't budget using the seller's tax bill. Ask your agent or lender to estimate taxes based on your purchase price.

File for homestead as soon as you can

If the home is your primary residence, the homestead exemption is the single biggest thing you can do to lower your bill:

• For 2026, the standard exemption includes up to $25,000 for all property taxes, plus an inflation-adjusted additional exemption of up to $26,411 for non-school taxes, applied to assessed value above $50,000. The maximum standard reduction for non-school taxes is $51,411, depending on assessed value.
• It starts your own Save Our Homes cap, so your assessed value can only rise 3% or by inflation each year from then on.

To qualify, you must own the home and live in it as your primary residence on January 1, and apply by March 1 of that year. In Duval County, you can apply online through the Property Appraiser's website.

Thousands of Jacksonville homeowners are missing out

In June 2026, a News4JAX investigation found more than 24,000 Duval County homeowners who appear to qualify for homestead but never filed. One expert estimated the missed savings at about $900 a year per home.

You can check your own status: look up your property on the Duval County Property Appraiser's website. If the value summary shows no homestead exemption, contact the Property Appraiser to check your eligibility and application status.

Moving within Florida? Bring your savings with you

If you already had a homestead in Florida, portability may let you transfer up to $500,000 of your Save Our Homes benefit to your new home. You generally need to establish the new homestead within three years. Ask the Property Appraiser's office about your situation when you apply.

What's on the November 2026 ballot

Florida voters will decide Amendment 3 in the November 2026 election. If approved, it would raise the homestead exemption for non-school taxes to $150,000 in 2027 and $250,000 in 2028, with inflation adjustments thereafter, and lower the annual assessment-increase cap for non-homestead property from 10% to 5%. People who are not Florida residents on December 31, 2026, would generally receive the increased exemption beginning with their fifth year of exemption, to the extent permitted by the U.S. Constitution. It needs 60% of the vote to pass. If it passes, we'll explain what it means for Jacksonville buyers.

The bottom line

Your first tax bill after buying will probably be higher than the seller's. Plan for it, file for homestead right after you move in, and your taxes will be far more predictable from then on.
