Londonderry NH Schools and Property Taxes: Why Is the Rate So Low in 2026?

Everyone talks about the price of living in Londonderry NH. Nobody talks about this tradeoff.

You see a low tax rate and you feel relief. I get it. When you're stretching to buy, every dollar counts.

If you've been burned by a tax bill you didn't plan for, you aren't alone. The rate is only half the story. The other half is the value the town puts on your house.

So let's look at Londonderry NH the way you'd look at a real bill. Every number here comes from the town or the state, and I'll show you where.

A low tax rate is a good start. Your real bill is the finish line.

What's the property tax rate in Londonderry NH?

The 2025 Londonderry NH tax rate is $14.47 per $1,000 of assessed value. In 2024 it was $16.14.

Assessed value is the value the town puts on your home for taxes. To estimate your bill, divide that value by 1,000. Then multiply by the rate.

Here's how the town breaks down the 2025 rate:

You won't know the 2026 rate until the state sets it later this fall.

Why did the Londonderry NH tax rate drop in 2025?

The town updated every property's value in 2025, and higher values usually bring a lower rate.

A revaluation is when the town updates values to match the market. State law calls for a full update at least every five years. Londonderry NH normally updates every two years, so the changes are smaller and more frequent.

Here's why it was due. In 2024, Londonderry NH homes were assessed at a median of 85.3 percent of market value. The state target is 90 to 110 percent. The 2025 update used more than 500 qualified sales.

The town says it plainly. A higher assessment doesn't automatically mean a higher bill. If your value rose more than the town average, your bill likely went up. If it rose less, it likely went down.

How much of a Londonderry NH tax bill goes to schools?

About 72 percent of your rate goes to schools.

The local school part is $9.28 and the state education part is $1.08. That's $10.36 of the $14.47.

That's the biggest school share of the four southern NH towns I cover in this series. So when you pay taxes in Londonderry NH, you're mostly paying for schools. That matters for the ballot question below.

Does the lowest rate mean the lowest bill in Londonderry NH?

Not always. Your bill is your assessed value times the rate.

At the 2025 rate, you'd pay $1,447 a year for each $100,000 of assessed value. A town with a higher rate and lower values can still send a similar bill.

So if you're torn between two towns, skip the rate chart for a minute. Look up the assessed value of a real house you like in each one. Then do the math.

How does Londonderry NH compare with Derry NH, Pelham NH and Salem NH?

Londonderry NH has the lowest rate of the four and the biggest school share.

*The Derry NH district runs preschool through grade 8. High school is paid as tuition to Pinkerton Academy.

The state's average cost per pupil for 2022 to 2023 was $20,323. That's the newest year I could confirm on the state site. Londonderry NH was close to that average.

What's on the November ballot for Londonderry NH schools?

A school tax cap question is on every New Hampshire ballot on November 3, 2026.

A new state law put it there. The governor signed it on July 15, 2026. If your town passes it, the local school part of your tax could only grow with inflation and new construction. Bonded building projects don't count toward the limit.

It wouldn't cap the town, county or state education parts of your bill. If it passes, it starts July 1, 2027 and lasts two years unless voters renew it.

Since schools take the biggest share of the Londonderry NH rate, this vote may matter more here than in nearby towns. Some people see tax relief. Others worry about cuts to programs. Read the question before you vote.

Can you appeal your Londonderry NH assessment?

Yes, with an abatement. An abatement is a request to lower your assessment.

For the 2025 bill, the town's deadline was March 1, 2026. That pattern repeats each year. You file after the fall bill and before March 1.

You'll need proof that your value is too high. Accurate similar sales nearby are the best proof you can bring. I'm glad to pull them for your address.

Is Londonderry NH cheaper than living in Massachusetts?

It depends on your income and how you spend, not just the tax bill.

New Hampshire has no broad income tax on wages and no general sales tax. It leans more on property tax. Massachusetts taxes income and sales, and leans less on property.

So you can't compare two tax bills by themselves. You have to look at your whole year. There's a real answer for your numbers, and it takes about twenty minutes to work out.

This is general information, not legal, tax or lending advice. Check with your attorney, lender and CPA before you decide.

I'll guide you home.
