Key Takeaways
- Your town collects the tax, not a county: the municipal tax collector runs the sale under Conn. Gen. Stat. § 12-157.
- Interest runs at 18% a year: delinquent tax accrues 1.5% per month under § 12-146, and part of a month counts as a whole month.
- Notice arrives 9 to 12 weeks out: the collector posts, files, and mails the levy notice, plus three weeks of newspaper publication.
- The deed sits unrecorded for six months: it is lodged with the town clerk within two weeks of the sale, and title does not move meanwhile.
- Redemption is costly: it takes everything owed at the time of the sale, plus 18% a year on the buyer's full purchase price.
- Selling first is the clean exit: delinquent taxes are normally paid off at closing from the proceeds, with no redemption interest.
A Connecticut property tax sale is run by your town or city, not by a county. There is no county treasurer to call. The municipal tax collector handles the bill, the lien, the notice, and the sale itself. If you are behind on property taxes in Connecticut, the document that matters most usually arrives nine to twelve weeks before a scheduled sale date.
This guide covers the statute that governs the process, Conn. Gen. Stat. § 12-157, and the two other remedies a municipality can use instead. It also covers what undoing a completed sale costs, and why the months before the sale date are the practical window to sell.
What Is a Connecticut Property Tax Sale?
A Connecticut property tax sale is a public sale of the real estate itself, run by the municipal tax collector under Conn. Gen. Stat. § 12-157 to satisfy unpaid property taxes. The collector levies a tax warrant, gives statutory notice, and sells the property publicly to whoever offers the most. If nobody offers enough to cover the amount due, the collector may sell it to the municipality instead.
Connecticut sells the deed, not a certificate. One feature works in the owner's favor: the sale does not move title on the day it happens. A federal court put it plainly. "In Connecticut, unlike in other jurisdictions, title to the property does not pass until after the sale has taken place and the redemption period has expired." That is In re Jacobson, 523 B.R. 13, 21 (2014), quoted in the Connecticut Judicial Branch law library pathfinder on municipal tax sales.
No judge signs off on a § 12-157 sale. The same pathfinder calls the process "entirely extra-judicial." The tradeoff is strict procedure. Connecticut courts hold that the power to sell land for taxes is strictly construed, and that the collector must comply with every statutory provision (Associates Financial Services of America, Inc. v. Sorenson, 46 Conn. App. 721 (1997)).
Why There Is No County Tax Office to Call
Connecticut property tax is assessed and collected by each town and city, so the office that can stop a sale is your local tax collector. Tax equals assessment times the mill rate, divided by 1,000, and one mill equals $1.00 per $1,000 of assessment (Connecticut Office of Policy and Management, Mill Rates). Assessments are set at 70% of market value statewide.
Rates differ sharply between cities, and a revaluation can cut the rate while assessments climb, so the headline number alone does not tell you the burden. Hartford's real property rate is 69.95 mills for FY2027 (City of Hartford, September 2026). New Haven's is 39.962 mills on the 2025 Grand List (City of New Haven Tax Collector Division, 2026). Bridgeport's is 27.95 mills for FY2026-2027 (City of Bridgeport Tax Collector).
A $300,000 Bridgeport house is assessed at $210,000, which at 27.95 mills produces about $5,870 a year. Bridgeport taxes are assessed as of October 1, levied the following July 1, due in two installments, and liens are filed on June 30. Most Connecticut towns run a similar calendar.
Municipalities publish sale dates well ahead. Hartford has announced a tax sale for November 6, 2026 at 10:00 a.m. at the Hartford Public Library's downtown branch, 500 Main Street (City of Hartford, September 2026). If your town has scheduled one, the date and property list are usually posted in advance.
How Fast Does a Tax Lien in Connecticut Build?
A tax lien in Connecticut grows at eighteen per cent per annum, or 1.5% per month, from the date the installment became due under Conn. Gen. Stat. § 12-146. It is the most important number in the process, and it applies whether or not a sale is ever scheduled.
Three details make the effective cost higher than the stated rate:
- Each fractional part of a month counts as a whole month, so a payment one day late accrues a full month of interest.
- A minimum charge of two dollars per installment applies, unless the municipality's legislative body has voted not to impose it.
- The collector applies each partial payment to interest first, before any of it reduces principal. Interest also keeps accruing after a judgment.
The lien is created by statute, not by a filing. Under § 12-172 it exists from the October 1 assessment date in the year before the tax became due. It lasts two years after the tax or first installment became due, and takes precedence over all transfers and encumbrances. A collector can extend that life by filing a certificate continuing the lien in the land records under § 12-173.
The § 12-157 Timeline, Step by Step
The sequence starts with a demand and a levy and ends with a recorded deed roughly nine months later. Every stage below is set by § 12-157 or the sections it references, and every stage but the last leaves the owner something to do.
| Stage | Timing | What the owner can still do |
|---|---|---|
| Demand, then levy on the real estate (§ 12-155) | After 30 days past the due date | Pay in full, or ask what payment arrangements the town offers. |
| Notice posted, filed with the town clerk, and mailed certified to the taxpayer and every choate lienholder | Not more than 12, not less than 9 weeks before the sale | The filed notice records as constructive notice equivalent to a lis pendens. Paying, or closing a sale, ends it here. |
| Newspaper publication weekly for three weeks, plus certified mail sent twice more | First run 9 to 12 weeks out; mailings 5 to 8, then 2 to 4 weeks out | Confirm the payoff with the collector; interest and § 12-140 charges keep moving. |
| Public sale (§ 12-157(c)) | The posted date, unless adjourned | The collector may adjourn. If nobody offers enough, the municipality may take the property. |
| Collector executes a deed and lodges it with the town clerk | Within 2 weeks after the sale | The deed stays unrecorded six months. Title has not moved, and redemption is open. |
| Post-sale notice published and mailed certified | Within 60 days after the sale | It names the sale date, the buyer, the price paid, and the expiration date. Keep it. |
| Redemption deadline (§ 12-157(f)) | 6 months after the sale, or 60 days if abandoned or covered by ordinance | Pay the full redemption amount and the deed is cancelled. |
| Deed recorded and takes full effect | After the redemption period expires unpaid | The window has closed. A claim for excess proceeds may remain. |
How Does the Six-Month Redemption Period Work?
The redemption period runs no later than six months after the date of the sale, and shortens to sixty days if the property was abandoned or meets conditions set by municipal ordinance (§ 12-157(f)). Redemption is not limited to the owner. The delinquent taxpayer, a mortgagee, a lienholder, or another affected encumbrancer may all pay. Payment goes to the tax collector, and the statute is specific about what it covers:
- The taxes, interest, and charges due and owing at the time of the sale.
- Interest on the total purchase price paid by the buyer, at eighteen per cent per annum from the date of the sale.
- Any taxes and debts owed the municipality that the sale did not recover.
- Additional charges under § 12-140: advertising, postage, record searches, deed drafting, attorney's fees, and land record filings.
The interest runs on the full purchase price, not on the tax balance. That is where redemption gets expensive. To illustrate the arithmetic only: say a house brought $90,000 at the sale and the owner redeems five months later. Interest on the purchase price alone is roughly $6,750, on top of everything owed at the sale.
Once the money is paid, the deed goes back to the collector for cancellation and a certificate of satisfaction is issued. The collector then has ten days to notify the buyer and tender the payment. A mortgagee or lienholder who redeems gains a claim against the person who owed the tax, with the lien's precedence.
If the property was abandoned, or meets conditions in a municipal ordinance, the window is sixty days. Owners of empty houses should confirm which clock applies before assuming they have half a year. Carrying costs on a vacant house keep compounding at 18% either way.
What Happens to Money Left Over?
Money above the delinquent taxes, interest, penalties, fees, and costs goes into an interest-bearing escrow account the municipality must keep separate from its other accounts (§ 12-157(i)). Interest earned there belongs to the municipality. What happens to the principal depends on whether anyone redeems.
If the property is redeemed, the escrow goes to the buyer within ten days. If it is not redeemed, the collector may apply the escrow to the taxpayer's other delinquent taxes owed that municipality, including on personal property and motor vehicles. Whatever remains goes to the clerk of the Superior Court within ten days of the redemption period expiring.
Within five days, the collector must notify the taxpayer and each affected lienholder by certified mail, naming the court, the amount, and the right to apply. Those parties then have ninety days from the date the collector paid the money in to file an application. The court may appoint a state referee to determine the equities. If nobody applies, the money escheats to the state under part III of chapter 32.
Tax Sale, Court Foreclosure, or an Assigned Lien
A Connecticut municipality has three separate ways to collect a delinquent property tax, and each runs on a different clock. Knowing which road your town took tells you what deadline you actually face.
| Remedy | Statute | Who runs it | The owner's window |
|---|---|---|---|
| Levy and public sale | § 12-157 | Town tax collector, no court | Before the sale date, then six months of redemption (or 60 days) |
| Tax lien foreclosure | § 12-181 | Superior Court, on suit by the collector | Until the redemption date the court sets |
| Assignment of the tax lien | § 12-195h | A private party that buys the lien | At least one year before the assignee may sue, then the court timeline |
Court foreclosure under § 12-181
The tax collector may sue to foreclose tax liens in the municipality's name under Conn. Gen. Stat. § 12-181. Municipalities holding liens on the same parcel may join in one complaint. The court may limit the time for redemption, order the real estate sold, or pass any other decree it judges equitable.
Assigned liens under § 12-195h
A municipality may assign its tax liens for negotiated consideration by resolution of its legislative body under Conn. Gen. Stat. § 12-195h. The assignee gets the same lien rights the municipality had and can foreclose or sue on the debt like any private lienholder. Assignments executed on or after July 1, 2022 carry real protections:
- A written contract is required, and the assignee cannot start a foreclosure suit until one year has passed since it bought the lien.
- The property owner is a third-party beneficiary entitled to enforce the assignee's covenants under that contract.
- The assignee must notify the owner and any mortgage holder of record within sixty days of the assignment.
- Holders of first or second security interests get sixty days' written notice before a foreclosure suit.
Selling a Connecticut House With Delinquent Property Taxes
You can sell a Connecticut house with delinquent property taxes, and the unpaid tax is normally paid off at closing out of the proceeds. A closing attorney requests the payoff from the collector, the amount comes off the top at settlement, and the lien is released. Timing is what changes the math, and three windows exist.
Before the sale date
This is the clean window. You still hold title, no deed has been executed, and paying the taxes, interest, and charges ends the process. A cash sale closing inside the nine-to-twelve-week notice period funds the payoff from proceeds, with no redemption interest. Cash transactions need no bank financing or appraisal, and can close in as few as 7 days.
During the six-month redemption period
You still hold title, because the deed sits unrecorded at the town clerk's office, so a sale remains possible. It now has to fund the full redemption amount, including 18% a year on the buyer's entire purchase price. That is a second window, not an equivalent one.
After the deed records
Once the redemption period expires unpaid and the deed is recorded, the sale is done. What may remain is a claim on excess proceeds, on the ninety-day schedule described above. If a collector's deed has already recorded, a Connecticut real estate attorney is the right call.
Where a cash sale fits
Propcash is a direct cash homebuyer, so we buy houses in Connecticut ourselves rather than listing them. Sellers pay no fees or commissions, the house is bought as-is, and the seller picks the closing date. When the problem is a tax clock rather than the building, that date is usually the point. You can request a cash offer on your Connecticut house and weigh it against redeeming, holding, or listing.
A tax delinquency rarely shows up alone. If a mortgage is also in default, Connecticut's strict foreclosure process runs on court-set Law Days, covered in our guide to stopping a foreclosure in Connecticut. If the house came through an estate, a fiduciary generally needs full administration before signing a deed, as our guide to selling an inherited house in Connecticut explains. Review the Connecticut seller disclosure requirements before signing, and see how Propcash buys on our Connecticut cash buyer page.

Let's chatFrequently Asked Questions
How long do you have to redeem a house after a Connecticut tax sale?
The redemption period runs no later than six months after the date of the sale under Conn. Gen. Stat. § 12-157(f). It shortens to sixty days if the property was abandoned or meets conditions set by municipal ordinance. The collector's deed sits unrecorded with the town clerk during that window, so title has not yet moved.
What does it cost to redeem a property after a Connecticut tax sale?
Redemption takes the taxes, interest, and charges due at the time of the sale, under Conn. Gen. Stat. § 12-157(f). It also takes interest on the buyer's total purchase price at eighteen per cent per annum from the sale date, plus municipal debts the sale did not cover. Because that interest runs on the purchase price rather than the tax balance, redeeming often costs far more than the original bill.
Can you sell a Connecticut house that has delinquent property taxes?
Yes. Delinquent property taxes are normally paid off at closing out of the sale proceeds, the same way a mortgage payoff is handled. The municipal tax lien under Conn. Gen. Stat. § 12-172 takes precedence over transfers, so a closing attorney gets the payoff from the collector and clears it before the deed records. As long as no collector's deed has been recorded, the owner still holds title and can sell.
What interest does Connecticut charge on late property taxes?
Delinquent property tax carries interest at eighteen per cent per annum, or 1.5% per month, under Conn. Gen. Stat. § 12-146. Each fractional part of a month counts as a whole month, so a payment one day late accrues a full month of interest. A two dollar minimum per installment also applies unless the municipality voted not to impose it.
Does a Connecticut tax sale wipe out the mortgage?
If nobody redeems in time, the post-sale notice required by Conn. Gen. Stat. § 12-157(f) warns that the titles, mortgages, liens, and other encumbrances of everyone who received notice are extinguished. That is why mortgage servicers watch these notices and often pay the taxes themselves. A mortgagee or lienholder also has its own right to redeem.
What happens to the extra money if a tax sale brings more than the taxes owed?
Conn. Gen. Stat. § 12-157(i) requires the municipality to hold any excess in an interest-bearing escrow account separate from its other accounts. If the property is redeemed the escrow goes to the buyer. If it is not, the collector may apply it to the taxpayer's other municipal debts and must pay the remainder to the Superior Court clerk, where an application must be filed within ninety days.
Can a Connecticut town sell its tax lien to a private buyer?
Yes. Under Conn. Gen. Stat. § 12-195h a municipality may assign its tax liens for negotiated consideration by resolution of its legislative body, and the assignee gains the same lien rights the municipality had. For assignments executed on or after July 1, 2022, a written contract is required and the assignee cannot sue to foreclose until one year after buying the lien. That contract also makes the owner a third-party beneficiary entitled to enforce the assignee's obligations.
