Why Is My Homestead Cap Zero? 5 Causes Explained

A homestead cap of zero on your property tax assessment means the Save Our Homes (SOH) benefit has not yet accumulated — most commonly because the property was recently purchased, a homestead exemption was newly applied, or the assessed value already equals the just (market) value.

What Is the Homestead Cap and Why Does It Show Zero?

The homestead cap — also called the Save Our Homes cap — limits how much the assessed value of a homestead property can increase annually. The cap is a calculated difference between your property's just value and its assessed value. When those two numbers are equal, the cap difference is zero — and that is completely normal in specific circumstances.

Florida's Save Our Homes (SOH) constitutional amendment, passed by voters in 1994 and effective in 1995, limits the annual increase in assessed value for properties with a homestead exemption to 3% or the Consumer Price Index (CPI) change, whichever is lower. Over time, in a rising market, this creates a growing gap between the property's market (just) value and its capped (assessed) value. This gap — the SOH benefit — reduces your taxable value and lowers your property tax bill.

The "cap" shown on your TRIM (Truth in Millage) notice or county property appraiser website shows the dollar amount of this benefit. When it shows $0, it means the assessed value is currently equal to the just value — the cap has not yet created a gap.

"The Save Our Homes benefit is the difference between the just value and the assessed value on properties with a homestead exemption. When the property is newly purchased, the assessed value is reset to just value as of January 1 of the year following the purchase, resulting in a cap benefit of zero until values diverge in subsequent years." — Florida Department of Revenue at floridarevenue.com

5 Reasons Your Homestead Cap Is Zero

Five scenarios produce a zero homestead cap. All of them are explained by the mechanics of how the SOH exemption calculates and accumulates.

Did You Purchase the Property Recently?

This is the most common reason for a zero cap. When you buy a home and apply for the homestead exemption, the assessed value is reset to the just (market) value as of January 1 of the year following your purchase. Since assessed value equals just value, the SOH cap starts at zero and only begins to diverge in subsequent years — but only if the market value increases faster than the 3% cap limit.

Example: You bought your home for $350,000 in June 2025. On January 1, 2026, the county sets your assessed value at $350,000 and your just value at $350,000. Cap benefit = $0. In 2027, if the market value rises to $380,000 (8.6% increase) but the cap limits the assessed value increase to 3%, your assessed value becomes $360,500 and your cap benefit becomes $19,500. The gap begins to grow.

Was the Homestead Exemption Newly Applied?

If the property previously lacked a homestead exemption (perhaps you recently moved in from out of state, or the property was an investment property and you are the new owner-occupant), the exemption is applied fresh. The assessed value resets to just value for the first year, producing a zero cap. Each subsequent year, the cap accumulates if market values rise faster than the 3% annual limit.

Has the Market Value Decreased or Stayed Flat?

The SOH cap only saves money when market values rise faster than the 3% annual limit. If the housing market declined or stayed flat, the county can actually increase the assessed value to catch up toward just value (but only up to 3% per year). In flat or declining markets, the gap between assessed and just value can narrow to zero even for long-held properties — there is simply no divergence to cap.

Did You Make a Qualifying Change That Triggered a Reset?

Certain ownership and use changes trigger a reassessment that resets the cap benefit to zero:
- The property was sold (new owner gets a reset)
- You changed the use from homestead to rental for more than one year
- You applied for homestead exemption on a new property after moving and applied the "portability" of your old SOH benefit

Portability is a related concept: when you move from one Florida homestead to another, you can transfer your accumulated SOH benefit to the new property. However, in the first year after portability is applied, the cap on the new property may still show reduced or zero until the new assessment is finalized.

Is There a Data Error on Your TRIM Notice?

While uncommon, errors do occur. A property appraiser's office may incorrectly fail to apply a homestead exemption, apply it to the wrong parcel, or calculate the SOH benefit incorrectly. If you have owned your home with a homestead exemption for several years in a rising market and your cap suddenly shows zero — check your county property appraiser's records online and contact the office directly if the numbers do not match expectations.

"Florida property owners with homestead exemption may transfer accumulated Save Our Homes benefits to a new Florida homestead. The portability amount is the difference between the just value and the assessed value on the previous homestead. The transferred benefit reduces the new property's assessed value, but in the first assessment year the benefit may appear partially applied or zero pending final calculation." — Florida Department of Revenue Property Tax Oversight at floridarevenue.com

How the Homestead Cap Accumulates Over Time

Note: The cap can never bring assessed value above just value — if market value falls, assessed value does not drop below just value via the SOH mechanism.

In Short

A homestead cap of zero is almost always expected — it means the property was recently purchased, the homestead exemption was newly applied, or the market has not risen enough to create a gap between assessed and just value. The cap begins to accumulate automatically in subsequent years as market values rise. If you believe there is an error and your cap should be nonzero, contact your county property appraiser's office directly.

What You Also May Want To Know

Does the homestead cap apply to all of Florida?

Yes. The Save Our Homes cap is a constitutional amendment that applies statewide to all Florida residential properties with a homestead exemption. Individual counties administer the property tax system but cannot change the SOH cap limit, which is set at the lesser of 3% or CPI increase annually.

What happens to my homestead cap when I sell my home?

When you sell, the SOH cap benefit transfers to the new owner only if they apply for and receive their own homestead exemption — and their cap resets to zero as described above. However, the seller can take the accumulated SOH benefit to a new Florida homestead via portability, transferring up to $500,000 of the benefit within three years of the sale.

Can I lose my homestead exemption?

Yes. If you move out and rent the property for more than a year, fail to re-file an exemption after moving, or fail to meet the Florida residency requirements (primary residence as of January 1), the exemption is removed and the assessed value reverts toward just value the following year.

How do I apply for homestead exemption in Florida?

File the application with your county property appraiser's office by March 1 of the tax year. Most counties accept applications online or in person. You will need proof of Florida residency (driver's license, voter registration) and documentation of ownership. First-time homestead exemption in Florida reduces the assessed value by $25,000 (and an additional $25,000 for assessed values between $50,000 and $75,000).
