Will your Florida property-tax bill match the seller's?
Know before you close.
Why the seller’s tax bill may differ from yours.
Not necessarily. Several tax benefits are tied to the owner, not the house. The seller's exemptions and assessment benefits generally do not carry over to you after the sale year, so the seller's bill can be a poor guide to yours. Florida Department of Revenue homebuyer guide, Section 193.155
This page explains the buyer’s tax reset, gives a simple example, and lists questions to ask before closing.
Key takeaway: Treat the seller's bill as background, not a forecast.
The reset, in one example
Here is a hypothetical. The numbers are illustrative, not a Florida average or an estimate of any real bill. The example follows one property before and after a sale. It assumes just value and millage rates do not change, and it excludes portability, exemptions and separate assessments.
| Before the sale (seller's assessment) | Buyer's first full-year assessment | |
|---|---|---|
| Just value (market value for tax purposes) | $400,000 | $400,000 |
| Assessed value | $220,000 (held down by yearly limits) | $400,000 (reset after the sale) |
| Tax at 17 mills (no exemptions) | $3,740 | $6,800 |
In this example, the seller's assessed value grew slowly under a yearly limit. After a sale, the home is generally reassessed at just value as of January 1 of the following year, so the change usually shows up on a bill well after closing. The sale-year bill may still reflect the seller's benefits. Applicable exemptions reduce assessed value to taxable value before the tax rates are applied; they are not subtracted from the tax bill. Section 193.155, Section 193.1554, DOR homebuyer guide
General educational information, not individual tax, legal or financial advice. The example does not estimate any particular bill.
Key takeaway: The reset is why your first full-year bill can differ sharply from the seller's.

Why escrow can change after you buy
If taxes are paid through escrow, your mortgage servicer estimates the amount to collect each month. Higher taxes can increase your monthly payment, and an escrow analysis may identify a shortage that you need to make up. How a shortage can be repaid depends on its size and on federal servicing rules. Ask your mortgage servicer how and when it reviews your escrow account.

Questions to ask your property appraiser and local taxing authorities
Your county property appraiser handles valuation, exemptions and portability. Millage rates and the basis for non-ad-valorem charges come from the taxing authority that levies them.
- What will this property be assessed at after the sale? (appraiser)
- Which exemptions can I apply for, and what is the deadline? (appraiser)
- Do I qualify to transfer an earlier homestead benefit (portability)? (appraiser)
- Which taxing authorities cover this address, and what are their millage rates?
- Are there non-ad-valorem assessments (charges not based on property value, such as fire or stormwater) on this parcel, and how are they calculated? (taxing authority)

Common questions
What is a mill, and how is my tax calculated?
In words: just value → assessed value → taxable value. Then: taxable value ÷ 1,000 × rate in mills = tax for that levy
- Just value: the property's market value as determined for tax purposes. DOR homebuyer guide
- Assessed value: the value after applicable assessment limits.
- Taxable value: assessed value after applicable exemptions. A property can have different taxable values for different taxing authorities.
- Millage: the tax rate. One mill is one one-thousandth of a dollar, so $1 of tax for every $1,000 of taxable value.
For example, $200,000 of taxable value ÷ 1,000 × 10 mills = $2,000 of tax for that levy. That is an illustration, not a complete bill. Different authorities apply different rates and exemptions, and non-ad-valorem assessments are separate charges not based on property value. Statutory definitions, Department of Revenue explanation
An exemption reduces taxable value. An assessment cap limits growth in assessed value. Neither, by itself, guarantees the total bill stays flat.
Do I get the homestead exemption automatically?
No. You apply through your county property appraiser. Generally, you must hold qualifying title and establish the property as your permanent residence as of January 1 of the tax year, and you apply by March 1. After initial approval, annual reapplication may be waived. Check your county's renewal process and report changes affecting eligibility. Late-filing provisions and exceptions exist, so confirm the current rules and deadline with your county property appraiser. Section 196.031, Section 196.011, Section 196.015
What is Save Our Homes?
Approved by voters in 1992, it limits yearly increases in a homestead's assessed value to the lesser of 3% or the specified Consumer Price Index change. It limits assessed-value growth, not market prices or the whole tax bill. It can cause a long-time owner's assessed value to sit far below market value. Section 193.155
What is portability?
Adopted in 2008, it lets an eligible owner transfer part or all of that Save Our Homes assessment benefit to a new Florida homestead, within limits. It transfers an assessment benefit, not cash or a guaranteed tax saving. The owner generally must have held a homestead exemption as of January 1 in any of the three preceding years, and the transfer is capped at $500,000 and reduced proportionally in some downsizing cases. Chapter 2026-239 changes portability calculation provisions beginning with the 2027 tax roll, so confirm the rules that apply to you with your county property appraiser. Section 193.155, Florida Constitution, Article VII, section 4, Chapter 2026-239
Why can similar homes on one street have different bills?
Assessment limits and exemptions can produce different taxable values for homes with similar market values. The same millage applied to different taxable values produces different bills. Actual outcomes depend on values, budget decisions, overlapping taxing authorities and other rules. Statutory definitions, Department of Revenue explanation
