In Auburn, Manchester Helps Pay the Property Tax Bill. Courts Have Argued Over How Much.

If you have spent any time comparing tax rates between Auburn and its neighbors, you have probably done the obvious thing: pulled up a rate per thousand, multiplied it against a home value, and moved on to the next town on your list. That math works fine for most of New Hampshire, where a town's tax rate is a straightforward function of what residents spend and what their homes are worth.

Auburn breaks that formula in a way that never shows up on a rate comparison chart. A meaningful piece of the town's revenue comes from a payer who doesn't live there, has never voted at Auburn's town meeting, and sends a check because a New Hampshire statute requires it. That payer is the City of Manchester, and the reason traces back to roughly 2,500 acres of lake that Manchester's water utility owns inside Auburn's borders.

The Land Auburn Can't Tax, and the Payment It Gets Instead

Lake Massabesic has supplied drinking water to the Manchester area since 1874, and it still serves more than 159,000 people across the region today, according to Manchester Water Works. Most of that lake and its surrounding watershed sits inside Auburn, but the land isn't owned by Auburn residents. It belongs to the City of Manchester, held by its water utility for the specific purpose of protecting the source.

Under normal circumstances, land owned by another municipality would simply be off Auburn's tax rolls, full stop. New Hampshire's legislature anticipated exactly this situation and wrote a fix into state law. RSA 72:11 exempts property held by one town or city inside another town for water supply or flood control from ordinary taxation, but it requires the owning entity to make an annual payment in lieu of taxes to the town where the land actually sits. The statute even specifies how that payment gets calculated: based on the average assessed value of the land over the three years before the water utility acquired it, adjusted over time to stay proportional with everyone else's assessments.

In plain terms, Manchester doesn't get the land for free, and Auburn isn't left holding an untaxed hole in its map. Auburn gets paid instead. That single mechanism means part of the town's annual revenue comes from an intergovernmental relationship rather than from the tax bills of the people who actually live there.

What Auburn Argued in Court, and What It Lost

The interesting part isn't that the payment exists. It's that the size of the payment has been argued over for decades, and the arguments get specific in ways that would surprise most buyers.

In one earlier round of litigation, Auburn tried to argue that Lake Massabesic's swimming ban, the same restriction that keeps the water clean enough to drink, shouldn't count against the property's value for tax purposes. Auburn's position was that the land should be assessed as if it had full recreational use, which the town said would raise its value by 25 percent and, in turn, raise the payment owed. The New Hampshire Supreme Court didn't buy it, ruling that activity restrictions on the lake, regardless of where they came from, still had to factor into what the land was actually worth. Auburn lost that argument, and the payment reflected a lake that residents and visitors are not allowed to swim in.

A later dispute, over land Manchester Water Works held for flood control, added another wrinkle. Manchester's utility had placed a conservation easement with the Society for the Protection of New Hampshire Forests on part of that land, an easement designed to keep the property undeveloped permanently. Auburn argued the easement existed mainly to shrink the utility's tax burden and assessed the land at $13.71 per $1,000 without factoring the easement in at all. The Water Works pushed back and sought an abatement.

Neither case is a scandal. They read like exactly what you'd expect from two governments negotiating, in court, over how to price land that neither one can simply sell. But the pattern matters more than any single ruling: the value of this land, and therefore the size of the check Auburn receives, has never been a fixed number. It moves with legal argument, reassessment, and the occasional easement.

Why This Matters If You're Comparing Auburn to a Neighboring Town

Here is the part that actually affects a buyer's decision, not just a matter of local trivia.

Most New Hampshire towns fund their budgets almost entirely through local property taxes, which means the tax rate you see is a fairly direct reflection of what residents spend and what their homes are worth relative to each other. Auburn's revenue picture includes a piece that isn't tied to any of that. It's tied to a nineteenth-century water supply agreement, a state statute, and a valuation that gets revisited through litigation rather than through a straightforward town vote.

That has a second, quieter effect on what you're actually buying into. Auburn's total land area runs close to 29 square miles, and roughly 12 percent of that is water, most of it Lake Massabesic. Add in the watershed buffer land and the conservation easements tied to the utility's flood-control parcels, and a real slice of the town will never appear as a buildable, taxable residential lot, no matter how strong the market gets. That scarcity isn't a temporary supply crunch that a builder could eventually solve. It's structural, and it has been for a century and a half.

Put those two pieces together and you get a town where the tax base is smaller than the map suggests, partially subsidized by a nonresident payer, and permanently limited in how much new taxable land can ever be added. None of that shows up when you're just comparing a rate per thousand across a spreadsheet.

As of mid-September 2026, Auburn's median list price was sitting around $821,000 across active listings, with homes typically carrying price points reflecting the town's mix of larger rural lots and septic-dependent construction rather than sewered, higher-density development you'd find closer to Manchester or Hooksett. If you're weighing that price against a neighboring town's, it helps to know the tax math behind it isn't built the same way.

A Few Things Worth Checking Before You Compare Numbers

If Auburn is on your shortlist against a neighboring town, a rate-per-thousand comparison alone will leave out the parts that actually explain the difference. Before you draw a conclusion, it's worth asking:

• What does Auburn's current assessed valuation report show for utility-owned land, and how large is the PILOT payment relative to the town's total budget this year
• Is the property you're considering on a public sewer line or dependent on a private septic system, since that affects both upfront cost and what can be built on adjacent parcels down the road
• Has the town's tax rate moved unusually in recent years, and if so, was it driven by local spending decisions or by a reassessment tied to utility-owned land

Auburn publishes its current tax rate directly, and it's worth checking the town's own tax rate page rather than relying on a third-party estimate, since the number is set annually by the state and can shift with each year's assessment.

A Few Questions Worth Asking

Does the Manchester Water Works payment lower my own tax bill in Auburn? It contributes to the town's total revenue, which reduces how much needs to be raised from residential and commercial taxpayers. It's one line among several, alongside county and state education components, so it won't show up as a separate discount on your bill, but it is part of what keeps the total burden from falling entirely on local property owners.

Can I build near Lake Massabesic? Land near the lake and its watershed carries buffer and wetland restrictions on top of ordinary zoning, and some parcels are covered by conservation easements that prohibit development outright. Anyone considering a lot near the water should verify its status with the town before assuming what's buildable.

Is this payment guaranteed to stay the same? No. It's grounded in a state statute that's been in place for decades and a water supply relationship over a century old, but the exact dollar figure has shifted before through reassessment and litigation, and there's no reason to assume it's locked in permanently.

Numbers on a listing page tell you what a home costs today. They don't tell you why a town's budget behaves the way it does, or what's permanently off the table for future development.
