Short answer: When a Sebastian property tax bill goes unpaid, the Indian River County Tax Collector sells a tax certificate on the parcel by June 1, and bidders compete on interest under an 18 percent yearly cap. The owner can redeem by paying the Tax Collector the face amount plus interest. Two years after April 1 of the issuance year, the holder can apply for a tax deed, and the Clerk of the Circuit Court then auctions the parcel online.

How does an unpaid Sebastian tax bill turn into a tax certificate?
A Sebastian property tax bill still unpaid on April 1 is delinquent, and the Indian River County Tax Collector must sell a tax certificate against the parcel on or before June 1.
A tax certificate is not a sale of the house or lot. It is a lien that a bidder buys by paying the overdue bill. Florida law makes property taxes a first lien, superior to all other liens (F.S. 197.122), and the Tax Collector describes the certificate as a first lien against real property (Indian River County Tax Collector). The same county calendar applies to every parcel in Sebastian, from a lot in the Sebastian Highlands to a house on Indian River Drive.
The steps before the sale are fixed. On April 1 a 3% penalty is added to the gross tax. Accounts that remain unpaid in May are charged an advertising fee and are advertised weekly in a local newspaper for three consecutive weeks (Tax Collector). For the Indian River County certificate sale itself, the Tax Collector points bidders to its Tax Certificate Sale website at LienHub.
The city's own charges ride on the same bill. The Tax Collector's list of levying authorities includes the Sebastian Stormwater Services Assessment, the Sebastian Waste Collection Assessment, the Sebastian River Improvement District, the Roseland Road Street Light District and the Vero Lake Estates MSBU (Non-Ad Valorem Taxes). The Sebastian Waste Collection assessment has applied since tax year 2024. Florida law makes non-ad valorem assessments on the bill subject to the issuance and sale of tax certificates and tax deeds for nonpayment (F.S. 197.3632), so an unpaid stormwater or garbage line on a Sebastian parcel is enforced the same way as unpaid millage.
One alternative exists before delinquency. Under the Tax Deferral Plan, a Sebastian homestead owner who meets age and household income conditions may defer part or all of the taxes and assessments, and the application must be submitted on or before March 31 (Tax Deferral Plan). The deferred portion becomes a priority lien that is paid on sale or change of ownership. The Tax Collector's Sebastian Office sits in Sebastian Corners on US 1, at 1921 U.S. Highway #1, and lists Property Tax among its services (Sebastian Office).
How does the Indian River County certificate sale set the interest rate?
At the Indian River County sale, bidders compete on interest, and each Sebastian certificate goes to the bidder asking the lowest rate, never above the 18 percent yearly cap in Florida law.
The rule is in section 197.432. Each certificate shall be awarded to the person who will pay the taxes, interest, costs, and charges and will demand the lowest rate of interest (F.S. 197.432). Bids move in fractional interest rate bids of one-quarter of 1 percent only, so competition on a Sebastian parcel can push the rate well below the ceiling. The ceiling is set in section 197.172: the maximum rate of interest on a tax certificate is 18 percent per year (F.S. 197.172). The same section blocks certificate interest during the 60-day period following the date of delinquency, apart from the 3 percent mandatory charge.
Not every Sebastian certificate goes to an investor. If a certificate is not purchased, it is struck to the county at the maximum rate of interest. A tax certificate representing less than $250 in delinquent taxes on homestead property may not be sold at auction and must be issued to Indian River County at the maximum rate (F.S. 197.432). The Tax Collector earns a commission of 5 percent on the delinquent taxes and interest, and that commission is built into the face value of the certificate.
The law also limits collection pressure on Sebastian owners. A certificate holder may not initiate contact with the owner to encourage or demand payment until 2 years after April 1 of the year of issuance, and unfair or deceptive contact is treated as an unfair and deceptive trade practice (F.S. 197.432). The timeline below follows one Indian River County certificate from delinquency to a possible deed sale.
| When | What happens | Office |
|---|---|---|
| April 1 after the tax year | Taxes delinquent, 3% penalty added | Tax Collector |
| May | Advertised weekly for three consecutive weeks | Tax Collector |
| On or before June 1 | Tax certificate sold, interest capped at 18 percent per year | Tax Collector |
| 2 years after April 1 of the issuance year | Holder may apply for a tax deed ($75 application fee allowed) | Tax Collector |
| Four consecutive weeks before the auction | Sale advertised once a week | Clerk of the Circuit Court |
| At least 20 days before the auction | Certified mail notice and sheriff notice to the titleholder | Clerk and Sheriff |
| 7 years after issuance | Certificate void if no tax deed was applied for | Tax Collector |
How does a Sebastian owner redeem a tax certificate?
A Sebastian owner redeems a certificate by paying the Indian River County Tax Collector the face amount plus all interest, costs and charges, at any time before the Clerk receives full payment for a tax deed.
Section 197.472 sets the window: a person may redeem a tax certificate at any time after the certificate is issued and before a tax deed is issued, unless full payment for a tax deed is made to the clerk, including documentary stamps and recording fees (F.S. 197.472). The Clerk's FAQ adds that the owner or mortgage holder may redeem the property from the tax deed sale by paying the amount owed, and the total redemption amount is collected by the office of the Tax Collector (Indian River County Clerk).
Redemption carries a floor. When the interest earned is less than 5 percent of the face amount, a mandatory minimum interest of an absolute 5 percent is levied on the face value, except on certificates bid at zero percent (F.S. 197.472). A certificate won at a 1 percent bid on a Sebastian parcel therefore still costs the owner at least 5 percent of the face amount in interest at redemption. The Tax Collector receives a fee of $6.25 for each tax certificate redeemed and pays the certificate holder within 15 business days.
Redemption is the usual outcome in Indian River County. The Clerk states that most of the properties advertised for sale will be redeemed and will not be auctioned (Clerk Tax Deed FAQ). Sebastian owners can handle property tax at the Tax Collector's Sebastian Office on US 1 or at the Main Office in the County Administration Complex, 1800 27th Street, Building B, Vero Beach (Tax Collector locations).
When can a tax deed be applied for on a Sebastian parcel?
A certificate holder can apply for a tax deed on a Sebastian parcel once 2 years have passed since April 1 of the issuance year, and the certificate dies if no application comes within 7 years.
The application goes to the Indian River County Tax Collector, which may charge a tax deed application fee of $75 (F.S. 197.502). A private applicant must also pay every other outstanding certificate on the parcel, any delinquent and current taxes, and the costs to bring the property to sale, including property information searches. If those costs are not paid within 30 days after notice from the Clerk, the application is canceled.
Indian River County has its own duty. The county shall apply for a tax deed on all county-held certificates on property valued at $5,000 or more on the Property Appraiser's most recent roll, and may apply on parcels valued below $5,000 (F.S. 197.502). Certificates that nobody pursues expire: seven years after the date of issuance, if a tax deed has not been applied for and no other proceeding exists of record, the tax certificate is null and void (F.S. 197.482).
Notice reaches Sebastian owners several ways. On receiving the application, the Clerk records a notice of tax deed application in the official records, effective for 1 year (F.S. 197.502). The Clerk then mails notice by certified mail at least 20 days prior to the date of sale, and the sheriff of the county where the titleholder lives also gives notice at least 20 days before the sale (F.S. 197.522). For an owner living in Sebastian, that is the Indian River County Sheriff.
How does the Clerk auction a Sebastian property for taxes?
The Indian River County Clerk of the Circuit Court auctions unredeemed Sebastian parcels online at indianriver.realtaxdeed.com, after advertising each sale once a week for four consecutive weeks.
The Clerk is statutorily responsible for conducting tax deed sales and issues the deed in the name of the County to the high bidder; no case is filed in court and no court order is issued (Clerk Tax Deed Sales). For non-homestead property, the opening bid equals the unpaid taxes and interest plus the Tax Collector and Clerk fees. For a Sebastian homestead, one half of the assessed value from the tax roll is added to the opening bid (Clerk Tax Deed FAQ). The certificate holder's bid also carries interest at 1.5 percent per month from the month after the application through the month of sale (F.S. 197.542).
Bidders register on the Indian River County sale site and post a deposit. The high bidder posts a nonrefundable deposit of 5 percent of the bid or $200, whichever is greater, and full payment of the bid, documentary stamp tax and recording fees is due within 24 hours, excluding weekends and legal holidays, or the sale is readvertised (F.S. 197.542). The Clerk states that the tax deed should arrive within 7 to 10 days from the sale date (Clerk).
A tax deed does not clean up title. The Indian River County Clerk states that the purchase of a tax deed does not warrant or guarantee clear and marketable title, and that most title insurance companies require a quiet title action first (Clerk Tax Deed FAQ). Under section 197.562, quoted by the Clerk, the grantee is entitled to immediate possession, and if possession is refused the purchaser may apply to the circuit court for a writ of assistance on 5 days notice.
What happens to surplus money and unsold Sebastian parcels?
When a Sebastian parcel sells above the opening bid, the Indian River County Clerk holds the surplus, pays government liens first, and mails notices to owners and lienholders.
Section 197.582 directs the Clerk to distribute the surplus to the governmental units for the payment of any lien of record, and to hold any balance for owners, mortgagees and lienholders. The statutory notice states that the surplus will be held by this office for 120 days, with senior liens paid before junior liens or the former property owner (F.S. 197.582). On a Sebastian homestead, the added one-half of assessed value is treated as surplus as well. The Clerk adds that unclaimed funds are transferred to the State of Florida, Department of Revenue, and that interpleader costs come out of the surplus (Clerk Tax Deed FAQ).
Some parcels find no buyer. When a certificate holder fails to pay, the land goes on a list called lands available for taxes (F.S. 197.542). On October 11, 2026, the Clerk's list for Indian River County showed two parcels, with original sale dates of 3/5/2018 and 5/13/2019, and the Clerk directs buyers to the Tax Collector at 772-226-1338 for the purchase price (Land Available for Taxes).
Sebastian residents do not need to drive to Vero Beach for Clerk services: the Clerk's Sebastian Office at 1921 U.S. Highway 1 is open Monday, Wednesday, Friday 8:30 am to 5 pm, phone (772) 226-1147, while the Indian River County Courthouse is at 2000 16th Avenue in Vero Beach (Clerk contact).

Frequently asked questions
Does a tax certificate mean a Sebastian owner has lost the property?
No. A tax certificate is a first lien bought by paying the overdue Indian River County bill. The owner keeps title and can redeem through the Tax Collector until the Clerk receives full payment for a tax deed, which cannot be applied for until 2 years after April 1 of the issuance year.
What is the highest interest a Florida tax certificate can earn?
Section 197.172 of the Florida Statutes caps tax certificate interest at 18 percent per year. Bidding at the Indian River County sale usually pushes the rate lower, but redemption carries a 5 percent minimum on the face amount unless the certificate was bid at zero percent.
Can an unpaid Sebastian stormwater or garbage assessment lead to a tax certificate?
Yes. The Sebastian Stormwater Services Assessment and the Sebastian Waste Collection Assessment appear on the county tax bill, and section 197.3632 makes non-ad valorem assessments collected that way subject to tax certificates and tax deeds for nonpayment.
Where are Indian River County tax deed auctions held?
The Clerk of the Circuit Court holds them online at indianriver.realtaxdeed.com. Each sale is advertised once a week for four consecutive weeks, and the winning bidder posts a deposit of 5 percent or $200, whichever is greater.
Who gets the money if a Sebastian parcel sells for more than the opening bid?
The Clerk pays government liens first, then holds the balance for mortgagees, lienholders and the former owner, who are notified by mail. Funds left unclaimed after the claim period go to the Florida Department of Revenue.
