What it means
When property tax goes unpaid, a local government still needs the money, so in places that use tax certificates it sells a claim against the property to an investor, who pays the unpaid tax, interest and costs. The government is paid at once, and the investor waits for the owner to repay.
A county tax collector in Florida describes the certificate as a first priority tax lien on real property that does not convey title to the land, so the sale is of the lien, not the property, and the buyer has no right to enter the property. The rules come from state and local law, so details differ, and Florida is the worked example here, so check the statute's current wording.
The owner can redeem the certificate: under Florida's statute, a person may redeem at any time after the certificate is issued and before a tax deed is issued, paying the face amount plus interest, costs and charges to the tax collector. The investor earns interest through that payment.
If the interest earned is under 5% of the face amount, the statute sets a mandatory minimum of 5%, and after redemption the tax collector pays the certificate holder within 15 business days, less a redemption fee. Not every owner pays.
In Florida, a holder can apply for a tax deed after two years have passed since April 1 of the year of issue, which starts a process that can end in a transfer of the property. There are protections for owners.
A holder may not contact the owner to encourage or demand payment until two years after April 1 of the year of issue, and one who does can be barred from future sales, while a certificate for under $250 in delinquent taxes on a homestead cannot be sold at auction. The risks are real.
Interest is paid only if the owner redeems, and the property may have other claims, so a buyer should research the parcel first.
In practice
Real-world examples.
Example
A fictional investor buys a certificate for 2,000 in unpaid tax. The owner redeems after one year, and the certificate rate was 3%. Interest of 3% on 2,000 is 60, which is less than 5% of 2,000, or 100, so the minimum applies and the payment is 2,100 before costs and fees.
Example
A fictional homeowner with a homestead exemption owes 200 in delinquent tax. Under the Florida statute, a certificate under 250 on a homestead cannot be sold at auction, and the tax collector issues it to the county instead. No outside investor can buy it.
Example
A fictional owner never pays, and the holder waits two years after April 1 of the issue year. The holder then files the certificate and an application for a tax deed. The owner can still redeem the certificate before the deed is issued.
Formula
Calculation
Redemption payment = Face amount + Interest earned + Costs and charges.
Floor rule in the Florida example: if interest is under 5% of face, use 5% of face. For a face amount of $2,000, 5% is $2,000 x 5% = $100, so the payment is at least $2,000 + $100 = $2,100 before costs and fees. If the bid rate would have produced only $60 of interest, the floor lifts it to $100, whereas $150 of interest above the floor is paid as bid, giving $2,150.Case study
Seen in the real world.
This case study is fictional and illustrative, and it follows Florida's statute as one example. Marcus buys a certificate on a small commercial lot for 3,000 in unpaid tax at a 2% bid rate. The owner redeems after eight months. Interest at 2% for part of a year is well under 5% of 3,000, so the floor of 150 applies and the payment is at least 3,150 before costs and fees. The tax collector pays Marcus within 15 business days, less the redemption fee.
Marcus earned 150 on 3,000 for eight months. He had no way to know when the owner would pay. The lesson is to read the local law. The floor, the timeline and the owner protections all come from the statute.
Watch out
Common mistakes.
- Believing a certificate buys the property, when it is a lien and the buyer has no right to enter or contact the owner early.
- Assuming the stated rate is the return, when a statutory minimum or the timing of redemption can change what is paid.
- Skipping research on the parcel, since other claims or a low property value can make the lien hard to collect.
Questions
People also ask.
Does buying a tax lien certificate make me the owner?
No. It gives a lien that earns interest if the owner redeems. Ownership can only change later through the tax deed process set by local law.
What happens if the owner pays?
The owner redeems by paying the tax collector the face amount, interest, costs and charges. The holder is then paid and the certificate ends.
Are the rules the same everywhere?
No. State and local law set how sales work, the interest rules and the timeline. The Florida rules here are one example, so check where the property is.
