Homestead Assessment Cap Calculator (Florida & Texas)
In Florida and Texas, once your home has a homestead exemption, the law limits how fast its assessed (taxable) value can rise each year, even when market values jump. This calculator shows how that gap can grow and what it might save. Estimate only; your property appraiser or appraisal district sets the real values.
How the caps work
Florida: Save Our Homes
Starting the year after you first get the homestead exemption, your assessed value can't go up by more than 3% or the change in the Consumer Price Index (CPI) for the prior year, whichever is lower. The assessed value can never be higher than market (just) value, and it can still rise a little when market value falls, until the two meet. The cap is set each year by the Florida Department of Revenue. Recent caps: 2026: 2.7%, 2025: 2.9%, 2024: 3.0%, 2023: 3.0%, 2022: 3.0%. Future caps aren't known yet, so the calculator uses the cap you enter (2.7%, the 2026 cap, by default) for every year; the law never lets it go above 3%.

Texas: 10% homestead cap
Starting January 1 of the tax year after you first qualify for the residence homestead exemption, your home's appraised value can't rise more than 10% a year, plus the value of any new improvements (such as an addition), and never above market value. Repairs and ordinary maintenance don't count as new improvements. The cap ends when neither the owner nor the owner's spouse or surviving spouse qualifies any more. The calculator doesn't include new improvements.

What the calculator assumes
- Savings = (market value − capped value) × your tax rate, before any exemptions. Exemptions such as Florida's up to $50,000 or the Texas school exemption lower your bill further; use the savings estimator for those.
- Your tax rate stays the same every year. Real rates change.
- Market growth is your own guess. Nobody knows future home prices.
- Florida's cap stays at the rate you enter. Texas's cap is fixed at 10% by law.
Moving? Florida lets you carry part of your Save Our Homes benefit to a new homestead: see Florida portability. Texas: moving and your Texas homestead. State rules: Florida · Texas. If your market value itself looks too high, see how to protest your assessment.
How much can my Florida assessed value go up each year?
After your first homestead year, by no more than 3% or the prior year's CPI change, whichever is lower. The Florida Department of Revenue set the 2026 cap at 2.7%.
How much can my Texas homestead appraisal go up each year?
No more than 10% a year plus the value of new improvements, starting the tax year after you first qualify for the homestead exemption, and never above market value.
Does the cap lower my tax rate?
No. It limits the value your taxes are based on. Your tax rate is set by local taxing units and can change every year.
Do I need to apply for the cap?
The cap comes with the homestead exemption. File your homestead exemption by your state's deadline; there's no separate application for the cap itself.
