How Massachusetts Tax Sales Work

Massachusetts runs no lien certificate sale and no outright deed auction. When property tax goes unpaid, the city or town usually takes the parcel into a tax title, which it holds as security for the debt under M.G.L. c. 60. Investors buy that title at a treasurer's auction, earn a fixed rate while they wait, and own the land only after they petition the Land Court and win a judgment. Since November 2024, even that judgment leaves the former owner a claim to any excess equity.

Municipal notices, auction venues and practices sit on the Massachusetts tax sales hub, and how to buy a Massachusetts tax title walks the buyer's sequence. If the redeemable model is new to you, tax liens compared to tax deeds explains where it sits, and the redeemable deed states table shows who else uses it.

Step 1: Find the city or town that holds the title

Massachusetts counties hold no tax sale. Each of the 351 cities and towns collects its own property tax and enforces it through its own collector and treasurer (ss. 43, 52, 53). The Massachusetts counties pages group municipalities by county for convenience, but every date and every parcel list belongs to one town.

No state office assigns or publishes dates. Many towns hire a licensed auctioneer, and one firm's municipal calendar can list dozens of Massachusetts towns side by side, often for town-owned or foreclosed land rather than tax titles. A date on that calendar belongs only to the town named beside it. Confirm it on that town's own notice.

Step 2: Know how a tax becomes a tax title

The tax is a lien on the land from January 1 of the assessment year. Bills are due July 1 for the fiscal year, though most towns bill quarterly or semi-annually, so due dates vary. Overdue tax bears interest at 14 percent a year (c. 59, s. 57).

Before acting, the collector mails a demand. If the tax is still unpaid 14 days later, the collector may either sell the parcel at a collector's sale or take it for the town after 14 days' notice. No statute sets a minimum delinquency age.

Here is the first trap. Towns take far more parcels than they sell, and a taking admits no bidder. The collector records an instrument of taking within 60 days and the town becomes the tax title holder. Newspaper lists headed "notice of tax taking" look like auction notices and are not.

Step 3: Pick the right auction

Several recorded steps look like sales and admit no investor: a taking under s. 53, the collector buying for the town when no bid covers the tax (s. 48), and a bulk transfer of tax receivables under s. 2C, which goes to the most responsible and responsive offeror judged on price, experience and a taxpayer-communication plan.

Three routes are open to an individual buyer:

• Treasurer's tax title auction (s. 52). The route investors actually use. The treasurer auctions titles the town already holds, individually or bundled, to the highest bidder for no less than the redemption amount. Notice runs 14 days published and posted, plus at least 10 days by mail to each owner of record.
• Collector's sale (s. 43). Rare. The price is fixed at the tax, interest and charges, and bidders compete to take the smallest undivided part of the land for that amount.
• Foreclosed town land. Once a town owns the parcel outright, it may sell through a custodian's auction (s. 77B), the broker-then-auction process of s. 64A, or a sale of low-value parcels without foreclosure (s. 79).

Step 4: Bid knowing the premium earns nothing

A tax title earns redemption interest of 8% a year, simple, under s. 62. The rate was 16 percent until St. 2024, c. 140 cut it, effective November 1, 2024. Nobody bids the rate down; at a treasurer's auction you compete on price.

That price is where the math turns. Your instrument of assignment states a principal and the interest accrued to the assignment date. On redemption you receive that stated amount plus interest on the principal alone from the assignment date. Anything you bid above the redemption amount earns nothing and is never repaid. Accrued interest you paid for at assignment is repaid but earns nothing further. No minimum return applies either, so a redemption one week after assignment pays one week of interest.

Run your bid through the tax lien yield calculator, which models the premium as dead money. One open question: the 2024 act has no transition clause, so the statute text does not say how interest on a title created before November 2024 is computed for the period before the cut. Confirm with the Massachusetts Division of Local Services before you price an older title.

Deposit and payment terms are mostly local. The state record reads: At a collector's sale, the purchaser must make an immediate deposit of whatever sum the collector considers necessary to show good faith, or the sale is void (s. 43). No statute sets a deposit for a treasurer's tax title auction or a custodian's auction; each municipality sets it in its terms of sale.

Two filings follow any purchase. You must record the instrument of assignment within 60 days, and a holder who lives outside the town must file a statement of residence and appoint a local agent (s. 47).

Step 5: Wait out redemption, which has no fixed end

The window in one line: At least 12 months from the sale or taking, then until a foreclosure petition is filed in the Land Court. Anyone with an interest in the land may redeem, and a mortgagee who redeems adds the cost to its mortgage debt. The treasurer can accept payment on your behalf and pays it over less a $10 fee.

Three details catch buyers:

• The clock may already have run. An assignee stands in the shoes of a purchaser at the ORIGINAL sale or taking, so a title the town has held for years may be ripe for a petition on the day you buy it.
• Extensions bind you. A treasurer who accepts a partial payment may extend the no-foreclosure period by up to 2 years, and an extension granted before assignment carries over to the assignee.
• Payment plans pause foreclosure. A town that adopts s. 62A by bylaw or ordinance can give an owner a payment agreement during which the treasurer may not foreclose.

Town-held parcels with abandoned buildings, or whose redemption amount exceeds assessed value, can be foreclosed sooner. See redemption periods explained for the national picture, and date your earliest petition with the redemption deadline calculator.

Step 6: Petition the Land Court for title

A Massachusetts tax title never ripens into ownership on its own. After the 12 months run, you petition the Land Court to foreclose all rights of redemption, and title becomes absolute only on its judgment (ss. 64, 65, 69). Until then you hold security and have no right to possession.

Filing a petition does not end redemption. A party may still file an answer offering to redeem, and the court can allow it on payment of the original sum, costs, interest, later taxes, the costs of the proceeding and a reasonable counsel fee. Budget for a contested case.

The judgment is also less final than it sounds. Any interested person other than the petitioner may move to vacate it within 1 year in extraordinary circumstances, or within 90 days where the petition rested on abandonment or an over-value certification, unless an innocent purchaser for value has acquired an interest or excess equity has been paid (s. 69A). The land stays subject to easements, restrictions and most covenants running with it. Read what survives a tax deed and quiet title after a tax deed before you plan a resale.

Excess equity changes the endgame

Since November 1, 2024, the owner at the time of foreclosure keeps a right to any excess equity, and the rule binds a private purchaser of tax receivables as well as the town (s. 64). Within 30 days after the judgment becomes final, the judgment holder must elect to retain or sell.

• Retain: obtain an independent appraisal within 120 days and pay out the appraised value above the tax title balance and costs.
• Sell: list with a licensed broker within 180 days, then auction at no less than two-thirds of appraised value if unsold after 12 months.

The money sits in a segregated interest-bearing escrow, and disputes go to the Superior Court with a jury trial right (s. 64A). For a buyer hoping to take a parcel worth far more than the tax, this changes the economics: the equity above the tax title balance and costs belongs to the former owner. The tax deed surplus funds guide compares how other states handle the same money.

No over-the-counter list

Massachusetts has no standing over-the-counter list. A town can assign a tax title only after a public auction, so there is no private counter purchase. Ask each treasurer what it holds and how it disposes of it, and see over-the-counter tax liens for how other states compare.

Putting it together

Massachusetts rewards the buyer who reads notices closely and prices for delay. Separate takings from auctions, bid close to the redemption amount because the premium earns nothing, check every title's original taking date and any extension, and budget for Land Court. Work through due diligence before a tax sale on every parcel before you bid.
