Quick answer: Londonderry NH property taxes run about $14.47 per $1,000 of assessed value for 2025, following the town's 2025 revaluation. That puts the typical annual bill for a median-valued home in the high-$6,000s to high-$7,000s range — and Londonderry's effective rate of roughly 1.61% actually sits below both the Rockingham County and statewide averages.

Londonderry is one of Southern New Hampshire's most in-demand towns — 10 to 15 minutes from downtown Manchester, about 40 minutes to Boston down I-93, with the airport partially inside its own borders and Mack's Apples on Mammoth Road standing in for everything people picture when they imagine the Granite State. But before you fall for the orchards and the open space, it's worth understanding exactly what you'll owe each year. Here's a clear, current look at Londonderry NH property taxes for 2026 buyers and homeowners.

What is the property tax rate in Londonderry NH?

Londonderry's 2025 property tax rate is approximately $14.47 per $1,000 of assessed value, the figure set each fall by the New Hampshire Department of Revenue Administration. The rate combines four pieces: the town (municipal) portion, the local school portion, the state education tax, and the Rockingham County portion — with schools making up the largest share, as they do in nearly every New Hampshire community.

New Hampshire has no state income tax and no general sales tax, so local property taxes carry most of the load for schools, roads, police, fire, and town services. That's the trade-off buyers relocating from Massachusetts quickly learn: bigger property tax bills, but no bite out of your paycheck or your shopping cart.

How much are property taxes on a typical Londonderry home?

Take the math step by step. Your bill is your assessed value divided by 1,000, multiplied by the tax rate. On Londonderry's median assessed value of about $482,300, the median annual property tax bill lands near $7,784, according to Ownwell's Rockingham County data. Bills across town range from roughly $6,155 at the 25th percentile to $9,416 at the 75th.

For a move-up buyer, scale it up: a home assessed at $585,000 — close to Londonderry's current median market value — would owe roughly $8,465 a year, or about $705 a month rolled into your escrow payment. With 30-year fixed mortgage rates averaging 6.58% in late July 2026 (Freddie Mac), that tax line matters as much as the rate when you're figuring out what you can truly afford.

Why are Londonderry NH property taxes lower than nearby towns?

Here's what surprises a lot of buyers: for Southern New Hampshire, Londonderry's rate is on the lower end. Recent per-$1,000 rates in nearby towns include Bedford around $16.49, Nashua around $16.83, Merrimack near $18.53, Hollis near $19.08, and Amherst near $20.07. Londonderry's $14.47 comes in under all of them.

A big reason is Londonderry's broad commercial and industrial base — the airport, distribution and manufacturing along the I-93 and Route 102 corridors, and the Woodmont commercial development all generate tax revenue that residential homeowners would otherwise shoulder alone. A larger non-residential tax base is one of the quieter reasons Londonderry NH property taxes stay competitive for a town this desirable.

Did the 2025 revaluation raise my Londonderry tax bill?

Londonderry completed a town-wide revaluation for the 2025 tax year, updating every property's assessed value to reflect current market conditions. New Hampshire law requires this periodically; by the 2024 tax year, the town's median assessment ratio had fallen to about 85.3%, meaning assessments trailed real sale prices and needed to be brought back to full value.

Two things to understand: first, a revaluation is not automatically a tax increase — when assessed values rise across the board, the tax rate typically drops to raise the same total budget. Second, individual bills still shift, because homes don't all appreciate at the same pace. Some Londonderry owners saw meaningful jumps while others changed little. If your new assessment looks out of step with what your home would actually sell for, you can appeal to the town Assessor; details and deadlines are posted on the Town of Londonderry Assessing page.

How do Londonderry property taxes compare to the rest of New Hampshire?

Londonderry's effective property tax rate of about 1.61% sits below Rockingham County's 1.76% median and New Hampshire's statewide 1.82% median. The typical New Hampshire homeowner pays roughly $6,700 a year in property taxes — among the highest in the country in absolute dollars — so Londonderry's below-average effective rate is a genuine point in its favor, even as home values climb. Statewide, the median single-family sale price held at $575,000 in June 2026 (New Hampshire Association of Realtors), and Londonderry's median market value of roughly $585,000 tracks right alongside it.

When are Londonderry property taxes due?

New Hampshire towns bill property taxes semi-annually. Londonderry issues a first bill in the first half of the year (typically due around July) and a second, final bill in the fall (typically due around December) once the DRA sets the year's rate. Exact due dates are printed on each bill and posted by the town.

Are there property tax exemptions in Londonderry NH?

Yes. Londonderry offers the standard New Hampshire relief programs, including the elderly exemption, the veterans' tax credit, exemptions for the blind and disabled, and a solar energy exemption. Eligibility and dollar amounts are set locally, so check current thresholds with the town Assessing office before you assume you qualify.

Do property taxes affect what home I can afford in Londonderry?

More than most buyers expect. Lenders count property taxes in your monthly debt-to-income calculation, so a higher assessed value can shrink your approved price even at the same interest rate. Running the tax number alongside the mortgage — not after — is the single most useful thing a Londonderry buyer can do early.

The bottom line for Londonderry buyers and owners

Londonderry gives you a lot of what makes New Hampshire appealing — commuter access, strong schools, orchards and open space — while keeping property taxes more competitive than several of its neighbors. Understanding the rate, the 2025 revaluation, and how a bill is actually calculated puts you in a stronger position whether you're buying, selling, or appealing an assessment.
