Connecticut

What you are buying: a collector's deed, subject to redemption

There is no tax lien certificate at a Connecticut tax sale. Every real estate tax is a lien on the property from the assessment date (§ 12-172, Conn. Gen. Stat.), and when the owner does not pay after demand, the collector can levy on the real estate and sell it (§ 12-155(b)). At the auction the collector sells all of the real property to the highest bidder to pay the taxes, interest, fees and other charges (§ 12-157(c)(1)).

Within two weeks of the sale the collector executes a deed to the purchaser and lodges it with the town clerk, where it remains unrecorded for six months from the date of the sale (§ 12-157(e)). That is the whole investment in one sentence: you pay the price of the property up front, and you either get that money back with interest or the deed is recorded in your name.

Sales are run town by town, by each municipality's own tax collector, not by a county or the state. Connecticut towns decide when to sell and what gets sold: Enfield, for example, sends a residential property to tax sale when more than $5,000 is owed or it is more than two grand list years in arrears, and commercial, industrial or abandoned land with no dwelling after one year (Town of Enfield, Tax Sale – 2026). Another town will draw that line somewhere else.

How the auction works: up from the amount owed

Bidding runs upward. At the sale, the collector must post a written notice of all taxes, interest, fees and other charges due on each property (§ 12-157(d)), and that figure is the opening bid. Investors compete on price, not on the interest rate, because the rate is fixed by statute and nobody bids it down.

The collector may publish rules for the auction and hire auctioneers and clerks, and their cost is added to the taxes due from the delinquent taxpayer; when several properties are sold, shared costs are split equally among them (§ 12-157(d)). The same goes for advertising, title searches, attorney's fees and drafting the deed (§ 12-140). All of it is in the minimum bid you see on the day.

The practical rules are local. Southbury's 2026 bidder package is typical: register in person between 9:15 and 9:45 a.m. with a photo ID and a Social Security or federal ID number for whoever will take title; bring a $1,000 deposit for each property you want to win, by certified, bank or cashier's check only, no cash; the deposit is non-refundable if you win and then fail to pay; and the balance is due four days later by 2 p.m. (Town of Southbury, Bidder Information Package). If the winner defaults, the collector may go to the second-highest bidder at that bidder's price.

Southbury also posts final minimum bids the day before the auction, refuses bids below the minimum in the first round, and bars anyone who owes the town taxes or fines from bidding. The collector may adjourn any sale by announcement or posted notice, with written notice to the owner and lienholders if the new date is more than three days away (§ 12-157(b)), and a property can be withdrawn right up to the sale if the owner pays.

What the 18% actually pays

To redeem, the owner, a mortgagee or another lienholder pays the collector the taxes, interest and charges that were due at the time of the sale together with interest on the total purchase price paid by the purchaser at 18% per annum from the date of the sale, plus any other municipal debts the sale did not recover and the charges under § 12-140 (§ 12-157(f)).

Two words in that sentence do the work. Total purchase price: the 18% runs on your whole bid, not just on the taxes. And the overbid is protected. Anything the sale brings in above what is owed goes into a separate interest-bearing escrow account, and if the property is redeemed it is turned over to the purchaser within ten days of the collector receiving notice of redemption (§ 12-157(i)(1)(A)). The collector must notify you by certified mail within ten days of receiving the redemption money and tender the payment to you (§ 12-157(f)). The interest earned by the escrow account itself belongs to the town.

The return is 18% a year, but the year is short. On a $40,000 winning bid redeemed at the end of the six months, that is about $3,600, or 9% on your money for half a year. On a sixty-day redemption it is closer to $1,200. Southbury tells bidders that interest for the first month accrues when the winner pays the full bid to the town (Southbury, Bidder Information Package), so the clock starts on your payment, not on the auction day.

There is no lump-sum floor and no penalty tier: a quick redemption pays little. Connecticut's own delinquent-tax interest is also 18% a year, charged to the owner by the month (§ 12-146), which is why the arrears on a property that reaches tax sale are often large relative to its value.

Six months, or sixty days

The standard redemption period is six months from the date of the sale. It is cut to sixty days if the property was abandoned or meets other conditions established by an ordinance adopted by the town's legislative body (§ 12-157(f)). Towns use it: Southbury's June 25, 2026 sale ran on a sixty-day redemption period for abandoned properties under its own code of ordinances, and its June 4, 2026 sale set a redemption deadline of August 4, 2026, with deeds to be filed on August 5 (Southbury, Notice of Sale of Real Estate for Taxes).

Within sixty days after the sale, the collector must publish in a newspaper with daily circulation in the town, and send by certified mail to the owner and each affected mortgagee and lienholder, a notice with the date of the sale, the purchaser's name and address, the amount paid and the date the redemption period expires (§ 12-157(f)). Your name and your bid are public. Southbury confirms it will publish both, though not your phone number.

Until the deadline passes, the property is not yours. You may not enter it: Southbury's rules warn that trespassing on tax sale properties is a crime, before or after the sale, and that there are no inspections. What the statute does give you is a sufficient insurable interest to insure the buildings against fire and other loss, and the right to petition the Superior Court for a receiver or other relief if the property is in imminent danger of damage or of injuring someone (§ 12-157(g)). You are not liable for conditions on the property during the redemption period simply because you hold the tax deed, and a receiver's costs are added to what the redeeming party must pay you.

If nobody redeems: the deed, and what it does not clear

If the money is not paid within the redemption period, the deed shall be recorded and have full effect (§ 12-157(f)). The post-sale notice is what gives it teeth: it must warn that the owner's title and the mortgages, liens, restraints on alienation and other encumbrances of everyone who received actual or constructive notice of the sale will be extinguished.

The statutory form of the collector's deed says what survives. You take the property subject to taxes of the town that were not yet due when notice of the levy was first published, other liens in favour of the town, easements and restrictions benefiting other parcels, and interests exempt from levy and sale under federal law (§ 12-158(a)). Southbury adds that blight and environmental liens may remain, and that taxes falling due after the sale keep priority over the purchaser and may be a personal liability.

The deed is prima facie evidence of valid title (§ 12-159). A sale can only be undone on procedure if the challenger shows the collector neglected to give the notice required by § 12-157 to someone entitled to it, and that the person did not actually know of the sale within six months. Any action alleging the deed is invalid, other than for fraud, must be brought within one year from the date the deed was recorded (§ 12-159b). If you ask within ninety days of recording, the collector must give you an affidavit of the steps taken, which the town clerk records (§ 12-159).

The town's warranty is thin. The deed binds the municipality to defend the title against defects from the collector's own acts, but its liability is limited to what you paid plus reasonable amounts spent after recording to improve and operate the property, where those cannot be recovered from the true owner (§ 12-158(b)).

The excess goes to court, not to the town

If the property is not redeemed, the escrowed excess may first be used to pay the delinquent taxpayer's other debts to the town, on this or any other property, including motor vehicles. Within ten days after the redemption period ends, the collector pays the rest to the clerk of the Superior Court for the judicial district, and within five more days notifies the former owner and affected lienholders by certified mail (§ 12-157(i)(1)(B)).

They then have ninety days from the date of the payment into court to apply for it. A state referee may be appointed to decide who is entitled to what; neither the purchaser nor the town is a party unless it consents. Money nobody applies for escheats to the state (§ 12-157(i)(2)–(3)). For the former owner's side of that process, see Connecticut tax sale excess proceeds.

Where the sale is published, and what happens if nobody bids

The levy itself is made by notice. The collector posts a notice on a bulletin board in or near the collector's office, files one with the town clerk, who records it in the land records, where it works as a lis pendens, and sends one by certified mail to the owner and each affected mortgagee and lienholder, all nine to twelve weeks before the sale (§ 12-157(a)). The notice gives the owner's name, a description or map reference, the street address, the amount due and the date, time and place of sale.

The sale is also advertised in a newspaper at least once a week for three weeks, the first notice nine to twelve weeks out and the last two to four weeks before the sale, and the owner and lienholders get two more certified letters in the final weeks (§ 12-157(a)). In practice each town also posts the list online: Enfield's 2026 page lists every property, owner and amount owed, and points bidders to cttaxsales.com for the current list and the process; Southbury posts its legal notice, bidder package and past results.

If there is no bidder, or the bid is too low to pay what is due, the collector may sell the property to the town (§ 12-157(c)(2)), and another municipality holding a tax lien on the same property may also buy it (§ 12-157(h)). Southbury's June 4, 2026 results show both outcomes side by side: most parcels went to private bidders for $400 to $9,000, and two went to the Town of Southbury itself, for $15,867.41 and $690.72. Under its rules the collector may also re-offer an unsold property at the end of the auction and, at the collector's discretion, accept a bid below the minimum.

The other route: towns can sell their liens in bulk

A tax sale is not the only way a Connecticut town collects. By resolution of its legislative body, a town may assign its tax liens for consideration, at a price negotiated between the town and the assignee (§ 12-195h(a)). That is a private negotiated deal, usually for a portfolio, not an auction you can walk into, and it is why you may read about Connecticut “tax lien sales” that have nothing to do with a collector's auction.

The assignee steps into the town's shoes on priority, interest and collection costs, and may foreclose or sue on the debt (§ 12-195h(b)). Since July 1, 2022, an assignment is only valid if a written contract sets, among other things, the assignee's contact details, its attorney's fee rates, and a rule that no foreclosure may start until one year after the assignee bought the lien; the owner is a third-party beneficiary of that contract (§ 12-195h(c)). The assignee must notify the owner and mortgage holders within sixty days of the assignment, give sixty days' notice to first and second mortgage holders before foreclosing, and act in a commercially reasonable way throughout (§ 12-195h(d)–(g)).

A town can also foreclose its liens in court itself (§ 12-181). A continued tax lien that has sat in the land records for more than fifteen years from the tax's due date is invalid unless a foreclosure was started and a lis pendens recorded in that time (§ 12-175) — worth knowing if an old lien shows up in a title search on a property you are bidding on.

Six ways people lose money here

1. 1. Calling it a lien and pricing it like one

   You pay the full price of the property on the day, for 18% a year on that price only for as long as the owner takes to redeem (§ 12-157(f)).

2. 2. Counting on six months

   Towns can cut redemption to sixty days for abandoned property by ordinance (§ 12-157(f)). Two months at 18% is about 3%.

3. 3. Walking the property

   You have no right to enter during redemption; Southbury warns bidders that trespassing is a crime and there are no inspections.

4. 4. Bidding while you hold a mortgage on it

   Southbury bars lienholders from bidding: if one wins, the sale is cancelled, the minimum bid pays the taxes and only the overbid is returned, without interest.

5. 5. Forgetting a deposit per property

   In Southbury it is $1,000 by certified or bank check for each property you want to win, forfeited if you then fail to pay the balance.

6. 6. Assuming the deed clears everything

   Taxes not yet due at the first notice, other town liens, easements and federally protected interests survive (§ 12-158(a)), and the deed can be challenged for a year (§ 12-159b).
