How New Hampshire Tax Sales Work

New Hampshire sells no tax lien certificates, and no county runs a tax sale. The town collector files a lien in the town's own name, the town takes a tax deed if nobody pays within two years, and only then can an investor buy anything: land the town itself decides to sell. Every step of that chain is local, so the useful question is always which town, never which county.

Town-by-town sellers and notice channels sit on the New Hampshire tax sales hub, and how to buy tax-deeded land in New Hampshire walks the buyer's sequence. If lien and deed states still blur together, tax liens compared to tax deeds explains why New Hampshire sits on the deed side even though its process starts with a lien.

Step 1: Follow the town, not the county

Each town or city tax collector executes its own liens, and each town or city later sells its own tax-deeded land (RSA 80:61, 80:80). The New Hampshire counties pages group towns by county for convenience, but each town runs on its own schedule.

Towns often hire a private auctioneer, and one auction company's calendar may list several towns side by side. A date on that calendar belongs only to the town named beside it. No state or county office assigns or publishes sale dates.

Step 2: How a delinquent tax becomes a town lien

Tax unpaid on December 1 after assessment draws 8 percent a year interest (RSA 76:13). The collector then mails at least 30 days' notice by certified or registered mail, naming the last date and time payment will be accepted, and executes the lien to the town the day after that deadline.

The lien covers a 100 percent undivided interest, takes priority over all other liens, and goes on record at the county registry of deeds within 30 days. Section 80:63 is the line that closes the door on investors: only the municipality, the county or the state may acquire a tax lien on land and buildings.

Step 3: Know which events are not sales

Several steps look like a sale on a town website, and none of them admits bidders:

• The lien date. Collectors announce the last day to pay before liening. The lien goes to the town.
• The deeding notices. The 30-day notices to owners and mortgagees announce a deed to the town. No bidding follows them.
• The registry report. The collector's filing with the register of deeds is a recording.
• The warrant article. A town meeting vote authorizing the selectboard to sell tax-deeded land grants permission and sets no sale date.
• The 90-day notice. The letter to the former owner announces a future offering that the owner can still stop.

The real investor event is the town's own sale of land it already holds by tax deed.

Step 4: The two-year redemption belongs to the town

Redemption runs 2 years from the execution of the real estate tax lien, until the collector deeds the land to the lienholder. Anyone with a legal interest may redeem by paying the recorded lien plus 14 percent a year on the whole recorded amount from execution, plus costs and any later taxes the town paid at the same rate (RSA 80:69, 80:75). Partial payments are accepted.

That interest is paid to the lienholder, which is the town. A buyer of tax-deeded land earns none of it. Redemption periods explained sets this window against other states.

One exception exists. Under 80:80 II-a, a town that votes for it may auction its liens during the redemption period, by public auction or advertised sealed bids above a minimum it sets. The buyer then collects the redemption payment or takes the deed. Price carefully: the 14 percent runs on the recorded lien amount only, so anything you pay above that earns nothing and comes back to nobody. No statewide list shows which towns have voted this authority.

Step 5: The deed can stall or never come

After two years, and after 30 days' certified-mail notice to the owner and each mortgagee, the collector deeds unredeemed land to the town (RSA 80:76). The governing body may refuse the deed over environmental liability or another stated risk. The lien then stays in place, interest keeps running, the right to redeem continues with no fixed end, and no sale follows.

Even with the deed in hand, a town needs authority to sell. The annual town meeting (by majority vote) or the city council must authorize the governing body, for one year or "indefinitely, until rescinded." A town may also vote to keep the land for public use, and 80:91 says nothing obliges it to sell. Some parcels never reach the market.

Step 6: Watch for the former owner's repurchase

At least 90 days before offering tax-deeded land, the town must send the former owner, and any mortgagee notified of the deed, a certified-mail notice of the offering terms and the right to repurchase (RSA 80:89). The former owner has 30 days to give notice of intent, then 30 more to pay the back taxes, interest, costs and a penalty of 10 percent of assessed value. The penalty is waived if the land was the owner's principal residence.

If the town never sent that notice, the right runs for 36 months after the tax deed is recorded. So a listed parcel can be withdrawn before closing, and a sale date means little until the sale is held.

Step 7: Bid on the town's terms

The selectboard or city council sets the method, the minimum and the terms (RSA 80:80 II). Expect one of three formats: an in-person public auction, often run by a hired auctioneer at town hall or on site; an advertised sealed-bid sale with bids opened at a stated time; or a broker listing, where the governing body finds that method in the public interest.

No statute ties the minimum to the taxes owed, and some towns set none. Deposits and payment deadlines come from each town's terms: No statewide deposit rule; the governing body sets deposit, registration and payment terms under 80:80 II. Read the town's terms of sale.

Budget the transfer tax too. RSA 78-B:1 charges $.75 per $100 of price to the buyer, with a $20 minimum at $4,000 or less, and the exemptions do not reach a town's sale of its tax-deeded land. Run due diligence before a tax sale on every parcel before you bid.

Step 8: Price the title you actually receive

The statute does not prescribe the form of the town's deed or any warranty it carries, so read each town's terms. A challenge to the lien or the collector's deed is barred only after a decade from the deed's recording (RSA 80:78), and a title examiner will look hard at the notice steps inside that window. Without the mortgagee notices of 80:65 and 80:66, the collector's deed is not valid against that mortgagee.

Order a title search and budget for a court action. Read what survives a tax deed and quiet title after a tax deed before you set a price.

Where the surplus goes

From the sale price the town keeps only its back taxes, interest, costs and penalty. Section 80:90 defines those to include the taxes that would have accrued while the town held the land, its legal and holding costs, and the penalty of 10 percent of assessed value. Any excess goes into the county superior court within 60 days of settlement by a bill of interpleader, or straight to the owners where no lienholders exist and the owners are easy to find (RSA 80:88).

That duty ends 36 months after the tax deed is recorded. After Tyler v. Hennepin County (2023), that cutoff, the penalty and the town's power to hold land unsold are the provisions a court challenge would reach. The research behind this page found no amendment on the live statute pages, but could not rule out a recent act not yet published, so ask the town which rules governed its deed. The tax deed surplus funds guide compares other states.

Is there an over-the-counter route?

Not for liens. A broker-listed parcel can be bought whenever it is listed, but that is a town property sale on the town's terms. No statewide list of tax-deeded land exists, so ask each selectboard office or city assessor for its list and watch town websites and newspaper legal notices. See over-the-counter tax liens for how other states handle leftover inventory.

Putting it together

New Hampshire rewards the buyer who works town offices, selectboard minutes and legal notices rather than a county calendar. Confirm that the town holds the deed and has sale authority, check whether the 90-day notice went out, price the title with the decade-long challenge window in mind, and treat every listed date as tentative until the hammer falls.
