Florida property taxes start with the county assessor's estimate of your home's value, then multiply that by your local tax rate

Your property tax bill in Florida is the result of two separate numbers: what your county assessor says your property is worth, and the millage rate set by your county and local taxing authorities. The assessor determines value; the tax rate is set by elected officials. You pay tax on the assessed value, not the market price you paid or could sell for. The formula is straightforward — assessed value times the millage rate equals your annual tax — but understanding each piece helps you know where to challenge if the number seems wrong.

Florida law caps how much the assessed value can rise each year, even if your home's market value climbs faster. This is called the Save Our Homes amendment, and it limits annual increases to 3 percent or the rate of inflation, whichever is lower. The cap resets to market value if you sell the property or transfer it to someone outside your when ready family. This rule is one reason Florida property taxes can feel lower than in other states — but only if you have owned your home for years.

Key Takeaways

  • The county assessor estimates your property's market value each year, and your tax is calculated on that assessed value multiplied by the local millage rate.
  • Florida's Save Our Homes amendment limits how much your assessed value can increase annually, capping it at 3 percent or the inflation rate, whichever is lower.
  • Homestead exemption reduces your assessed value by a set amount (usually $50,000), which directly lowers your tax bill if you own and occupy the home as your primary residence.
  • Millage rates vary by county and by the specific taxing districts that serve your property, so two homes with the same assessed value can have different tax bills.
  • You can challenge your assessed value through the county's value adjustment board if you believe the assessor's estimate is too high.

How the county assessor determines your home's value

The county assessor's office estimates the market value of every property in the county, usually once per year. They use sales data from comparable homes, the condition and age of your structure, lot size, and features like square footage and number of bedrooms. They do not always inspect every home — many assessments rely on public records and previous valuations. If your home is new or recently sold, the assessor has recent market data. If you have owned it for decades, the assessment may be based on older sales or a formula applied to similar homes in your area.

The assessed value is not the same as the appraised value a bank uses for a mortgage, and it is not the same as what you could sell your home for today. It is the assessor's estimate of fair market value for tax purposes. In some years, especially after a real estate boom, the assessed value can lag behind actual market prices. In other years, it can exceed what buyers are willing to pay. This gap is why homeowners sometimes challenge assessments — if comparable homes sold for less than the assessor's estimate, you have grounds to dispute it.

The homestead exemption and other reductions to assessed value

If you own your home and live in it as your primary residence, you may be may have access to to a homestead exemption. This exemption reduces your assessed value by a set amount before the tax rate is applied. The first $50,000 of assessed value is exempt from school property taxes for all homeowners. An additional $25,000 exemption applies to non-school taxes (county, municipal, and special district taxes) for homeowners who meet the residency requirement. Together, these can reduce your assessed value by up to $75,000, which translates directly to lower taxes.

You must file for homestead exemption with your county property appraiser's office, usually by March 1 of the year you want it to take effect. You will need proof of residency, such as a driver's license or utility bill, and proof of ownership. Once granted, the exemption carries forward each year unless you move or sell. If you transfer the property to a family member, the exemption may transfer as well under Florida's portability rules, but the rules are specific — consult your county appraiser's office to confirm your situation.

Other exemptions exist for veterans, disabled persons, and agricultural land, but they have their own requirements and process processes. The homestead exemption is the most common and the one most owner-occupied homes use.

Understanding millage rates and how they vary by location

The millage rate is the tax rate applied to your assessed value. It is expressed in mills — one mill equals $1 of tax per $1,000 of assessed value. If your assessed value is $200,000 and the millage rate is 10 mills, your tax is $2,000. Millage rates are set by county commissions, city councils, school boards, and special taxing districts. Your property may fall within multiple districts, each with its own rate, and all of them add together to create your total millage rate.

A property in one county can have a very different millage rate than an identical property in another county, or even a different rate than a home a few blocks away in a different school district or municipality. This is why two homes with the same assessed value can have significantly different tax bills. You can find your property's specific millage rate on your property tax bill or by contacting your county property appraiser's office. The rate can change year to year if local governments adjust their budgets.

The Save Our Homes amendment and the assessment cap

Florida's Save Our Homes amendment, passed in 1992, prevents assessed values from rising more than 3 percent per year or the inflation rate, whichever is lower. This cap applies only to homesteaded properties — homes where the owner lives and has filed for homestead exemption. The cap means your assessed value can grow much slower than your home's actual market value, especially in a rising market. Over time, this creates a significant tax advantage for long-term homeowners.

The cap resets to current market value if you sell the property or if you transfer it to someone outside your when ready family. If you transfer it to a spouse, child, or grandchild, the cap may transfer as well, but the rules are complex and depend on the relationship and the timing of the transfer. When you buy a home, your first assessed value is based on the purchase price or the appraiser's estimate of market value, whichever is lower. From that point forward, the 3 percent cap applies until you sell or transfer outside the family.

How to find and understand your property tax bill

Your property tax bill is mailed by the county tax collector, usually in November for taxes due by March 31 of the following year. The bill shows your assessed value, the homestead exemption amount (if you have one), the taxable value after exemptions, the millage rate or rates, and the total tax owed. It also lists the different taxing authorities — school board, county, city, special districts — and how much each one is collecting from your payment.

If you do not receive a bill, contact your county tax collector's office. You can also view your property record and assessment online through your county appraiser's website, which usually has a searchable database. This is where you can see the assessed value, the exemptions applied, and sometimes the comparable sales data the assessor used. Reviewing this information before you receive your bill gives you time to gather evidence if you plan to challenge the assessment.

Challenging your assessed value through the value adjustment board

If you believe your assessed value is too high, you can file a petition with your county's value adjustment board (VAB). The important date is usually 25 days after your property tax bill is mailed. You do not need a lawyer, and there is no fee to file. You will need to show that the assessor's value is higher than the fair market value of your property. Evidence includes recent sales of comparable homes, a professional appraisal, or documentation that your home has physical defects the assessor did not account for.

The VAB is made up of county officials and citizens, and they hold hearings where you can present your case. If you win, your assessed value is reduced, which lowers your tax bill for that year and potentially future years (subject to the 3 percent cap). If you lose, you can appeal to the Florida Department of Revenue, though this is less common. Many homeowners successfully challenge assessments by straightforward showing the VAB that comparable homes in their neighborhood sold for less than the assessor's estimate.

Frequently Asked Questions

Can I lower my property taxes by appealing my assessment?

Yes, if you can show the county value adjustment board that your assessed value is higher than the fair market value of your home. You have 25 days after your tax bill is mailed to file. Bring evidence such as recent sales of similar homes in your neighborhood or a professional appraisal. Many successful appeals are based on comparable sales data alone.

What happens to my property taxes if I sell my home?

Your assessed value resets to the sale price or the appraiser's estimate of market value, whichever is lower. The Save Our Homes cap does not carry over to the new owner unless they are your spouse or child and meet specific transfer requirements. The new owner's assessed value will then be capped at 3 percent annual increases until they sell.

Do I have to file for homestead exemption every year?

No. Once you file and are approved, the exemption carries forward automatically each year as long as you continue to own and occupy the home as your primary residence. You only need to file once, unless you move or sell the property.

Why is my property tax bill higher than my neighbor's if our homes look the same?

Your assessed values may differ based on when each home was last sold, the condition noted in the assessment, or differences in lot size or features. You may also live in different taxing districts with different millage rates. Request your neighbor's millage rate and assessed value to compare, then contact your county appraiser if the difference seems unjustified.

How often does the county assessor update property values?

Most Florida counties reassess all properties annually, though some use a longer cycle. The assessed value is typically updated once per year, and you receive notice of any change before your tax bill is mailed. You can challenge the new value through the value adjustment board if you disagree with it.
