TL;DR
Florida collects delinquent property taxes through a two-step system in Chapter 197 of the Florida Statutes: the tax certificate sale and, later, the tax deed sale. Property taxes become a first lien on the property on January 1 of the tax year, superior to almost all other liens, and they are due by March 31, becoming delinquent on April 1. When taxes go unpaid, the county tax collector sells a tax certificate on the property — an interest-bearing lien that an investor buys by paying the delinquent taxes, bidding down the interest rate they are willing to accept. The certificate does not transfer ownership; it is a claim for repayment with interest. The owner can redeem after the certificate is issued and before a tax deed is issued — unless full payment for the tax deed has already been made to the clerk of court, including documentary stamps and recording fees — by paying the face amount plus interest, costs, and charges under §197.472. If the taxes remain unpaid, the certificate holder may apply for a tax deed after two years from April 1 of the year the certificate was issued, which triggers a public auction of the property itself conducted by the clerk of court. Only at the tax deed sale does ownership actually change hands. This is entirely separate from mortgage foreclosure: a tax certificate and tax deed enforce the government's tax lien, not a lender's mortgage, and the tax lien's superior priority means a tax deed can wipe out most other interests in the property.
How the tax lien arises
Florida funds local government substantially through ad valorem property taxes, and Chapter 197 gives those taxes powerful collection teeth. Under §197.122, all property taxes are a first lien on the property, superior to all other liens, running from January 1 of the year the taxes are levied until they are paid. This priority is what makes the system work: because the tax lien outranks mortgages and most other claims, the state can ultimately force a sale that clears those junior interests.
Taxes are payable starting in November and become delinquent on April 1 of the following year if unpaid. Every property owner is charged by law with knowing that taxes are due annually — there is no excuse of lack of notice. Once taxes are delinquent, the collection machinery of Chapter 197 begins, moving first to the tax certificate sale. For how the underlying tax amount is set in the first place, see our guide to the property tax assessment process.
The tax certificate sale
The first enforcement step is the sale of a tax certificate, not the property. By around June 1, the tax collector must advertise the delinquent parcels and sell tax certificates on them, typically through an online auction. A tax certificate is a legal document representing the unpaid delinquent taxes, interest, and costs — essentially a transferable lien against the specific parcel.
The auction runs on a reverse-bid basis: investors bid down the interest rate they are willing to accept, starting from a statutory maximum of 18% and going lower, and the certificate is awarded to the bidder accepting the lowest rate. The investor pays the delinquent taxes, and in exchange holds a certificate that earns that bid rate of interest. Critically, buying a certificate does not make the investor the owner and gives no right to possess or enter the property; it is purely a financial lien that will either be redeemed for a return or, eventually, converted toward a tax deed. Certificates on homestead property below a small statutory threshold are struck to the county rather than sold.
| Stage | What happens |
|---|
| January 1 | Property taxes become a first lien (§197.122) |
| April 1 | Unpaid taxes become delinquent |
| By ~June 1 | Tax collector sells tax certificates (interest bid down from 18%) |
| After 2 years | Certificate holder may apply for a tax deed (§197.502) |
| Tax deed sale | Clerk auctions the property; ownership transfers |
Redemption: the owner's escape
Between the certificate sale and the issuance of a tax deed, the property owner retains the right to redeem. Under Chapter 197, redemption means paying the delinquent taxes, the accrued interest at the certificate's rate, and the associated costs and fees. When the owner redeems, the certificate holder gets their investment back plus the earned interest, and the lien is cleared.
Under §197.472, redemption is available after the certificate is issued and until a tax deed is issued, unless full payment for the tax deed has already been made to the clerk — the owner does not lose the property the moment a certificate is sold. This long redemption window is why a tax certificate is often described as an investment in the interest rate rather than in the property: most certificates are redeemed, and the investor's return is the interest, not the real estate. Only when the taxes stay unpaid long enough for the certificate holder to force a tax deed sale does the property itself come into play.
The tax deed sale
If a certificate remains unredeemed, the holder may move to collect by forcing a sale of the property. Under §197.502, a certificate holder may apply for a tax deed once two years have passed from April 1 of the year the certificate was issued. To apply, the holder must pay off any other outstanding certificates, plus current taxes and the costs of bringing the property to sale.
A tax certificate is not open-ended: under §197.482, it becomes null and void and is canceled seven years after issuance if no tax deed has been applied for and no other qualifying proceeding is of record. The application triggers a public auction conducted by the clerk of the circuit court, with statutory notice to the owner and other interested parties. At that tax deed sale, the property is sold to the highest bidder, and ownership finally transfers by tax deed. Because the tax lien was a first lien superior to most others, a properly conducted tax deed sale extinguishes most junior interests, including many mortgages — a key reason lenders monitor tax payment closely and often escrow taxes. For the parallel process by which a mortgage lender, rather than the government, forces a sale, see our guide to judicial foreclosure under Chapter 702.
How tax deeds differ from mortgage foreclosure
It is easy to confuse a tax deed sale with a mortgage foreclosure, but they are different mechanisms enforcing different debts. A mortgage foreclosure enforces a lender's contractual lien and, in Florida, proceeds judicially through the courts under Chapter 702. A tax deed sale enforces the government's statutory tax lien through the Chapter 197 certificate-and-deed process administered by the tax collector and clerk, not a mortgage lender.
The priority difference is decisive. A mortgage is generally junior to the tax lien, so unpaid property taxes can ultimately extinguish a mortgage through a tax deed sale, whereas a mortgage foreclosure does not eliminate the superior tax lien. For exam purposes, the key is to recognize which lien is being enforced and by whom: the tax collector and clerk under Chapter 197 for taxes, versus a court foreclosure for a mortgage.

Frequently Asked Questions
- What is a Florida tax certificate?
- A tax certificate is an interest-bearing lien the county tax collector sells when property taxes go unpaid, under Chapter 197. An investor buys it by paying the delinquent taxes and, through a reverse-bid auction, accepts an interest rate (bid down from a statutory maximum of 18%). The certificate does not transfer ownership or give any right to the property — it is a financial claim that is either redeemed with interest or later used to apply for a tax deed.
- When can a tax certificate holder get a tax deed?
- Under §197.502, a certificate holder may apply for a tax deed once two years have passed from April 1 of the year the certificate was issued, if the taxes remain unpaid. The holder must pay off other outstanding certificates, current taxes, and sale costs. The application triggers a public auction of the property conducted by the clerk of the circuit court, at which ownership finally transfers by tax deed.
- Can the owner get the property back after a tax certificate is sold?
- Yes. The owner may redeem after the certificate is issued and before a tax deed is issued — unless full payment for the tax deed has already been made to the clerk, including documentary stamps and recording fees — by paying the face amount plus interest, costs, and charges (§197.472). Selling a certificate does not transfer ownership, and most certificates are redeemed. Only if the taxes remain unpaid long enough for the certificate holder to apply for and complete a tax deed sale does the owner actually lose the property.
- Does a tax deed wipe out a mortgage?
- Often, yes. Property taxes are a first lien superior to most other liens under §197.122, so a properly conducted tax deed sale can extinguish junior interests, including many mortgages. This is why lenders monitor property-tax payment and frequently escrow taxes into the monthly payment. It is the opposite of a mortgage foreclosure, which does not eliminate the superior tax lien.
- How is a tax deed sale different from foreclosure?
- They enforce different debts. A tax deed sale enforces the government's statutory tax lien through the Chapter 197 certificate-and-deed process run by the tax collector and clerk. A mortgage foreclosure enforces a lender's contractual lien and proceeds through the courts under Chapter 702 in Florida. The tax lien's superior priority is the key difference: taxes can wipe out a mortgage, but a mortgage foreclosure cannot wipe out the taxes.
- What interest rate does a tax certificate earn?
- The rate is set by auction. Bidding starts at a statutory maximum of 18% and investors bid the rate down, with the certificate awarded to the bidder accepting the lowest interest rate. The winning investor then earns that bid rate on the amount paid until the certificate is redeemed. Because most certificates are redeemed before any tax deed, the interest is typically the investor's actual return rather than the property itself.
Bottom Line
Florida enforces delinquent property taxes through Chapter 197 in two steps. Taxes become a first lien on January 1 under §197.122, superior to most other liens, and go delinquent April 1. The tax collector then sells a tax certificate — an interest-bearing lien bid down from an 18% maximum — which does not transfer ownership but lets an investor collect the taxes plus interest. The owner may redeem after the certificate is issued and before a tax deed issues, unless full payment for the tax deed has already been made to the clerk, by paying taxes, interest, costs, and charges. If the taxes stay unpaid, the certificate holder may apply for a tax deed after two years under §197.502, triggering a clerk-run public auction at which ownership finally transfers. Because the tax lien is superior, a tax deed sale can extinguish junior interests such as mortgages — unlike a Chapter 702 mortgage foreclosure, which cannot wipe out the tax lien.
