A buyer scrolling Tolland listings this fall will notice something that doesn't quite add up. A smaller lot with a smaller house sometimes closes for more money per square foot than a much larger parcel down the road. Acreage looks like it should be the variable that drives price. In Tolland right now, it isn't, and the reason has less to do with the real estate market than with a state tax law most buyers have never heard of until it shows up on a closing statement.
That law is Public Act 490, and it explains why two properties that look nearly identical on a listing sheet can carry wildly different tax bills, and why one of them might come with a bill of its own the moment the sale closes.
Three September Closings, Three Different Price-Per-Square-Foot Numbers
Look at three homes that closed in Tolland between September 9 and September 14, 2026, according to a Patch roundup of recent sales. A three-bedroom home at 78 Willie Circle sold for $400,000 on a 0.71-acre lot, working out to $362.32 per square foot on its 1,104 square feet of living space. Down the road, 67 Pine Hill Road sold the same day for $449,900 on a 1.1-acre lot, but at 2,854 square feet, that price only comes to $157.64 per square foot. A third home, 523 Tolland Stage Road, sold September 11 for $601,700 on a 2.33-acre lot, landing at $208.27 per square foot.
The smallest lot in that set produced the highest price per square foot. The largest lot landed in the middle. If acreage were doing the pricing work here, that order would run the other way.
Buyers tend to explain this away as noise, three homes, three conditions, three negotiations. Some of that is true. But once you start looking at Tolland's larger parcels, especially raw land and lots over an acre or two, a second factor starts showing up that has nothing to do with condition or staging. It's how the land is taxed.
The Real Reason Some Big Lots Cost So Little to Hold
Connecticut's Public Act 490 lets land classified as farm, forest, or open space be assessed at its current use value instead of its fair market value, a distinction the state's issue brief on the program spells out directly: current use value reflects what the land is worth as it's actually being used, while fair market value reflects what it could fetch as a building lot or subdivision. For an owner sitting on several wooded or open acres, that gap can mean a property tax bill that looks nothing like what the acreage alone would suggest.
This is why a five-acre parcel can carry a tax bill lower than a half-acre house lot two towns over. It isn't that land is simply cheap to hold in Tolland. It's that a meaningful share of the town's large parcels are taxed under a completely different formula than the one buyers assume applies.
The Connecticut Department of Agriculture explains that state law sets no minimum acreage for farmland, while towns can set their own minimum acreage for open space. The Tolland Assessor's Office says forest land requires at least 25 contiguous acres, or multiple tracts adding up to that with no single piece under 10 acres. Open space has its own rules. Two six-acre lots sitting side by side could land on opposite sides of this system entirely, one qualifying for a use-value assessment and the other stuck paying full fair market rates, depending on how each has actually been used and whether an application was ever filed.
What Happens When the Classification Ends
The use-value assessment isn't free forever. Connecticut General Statutes Section 12-504a attaches a conveyance tax penalty to land that leaves its PA 490 classification within ten years of being classified, whether through a sale, a transfer, or a change in use. The tax is calculated on the property's fair market value, not its use value, and it declines on a fixed schedule the longer the land has held its classification.
| Year of Sale or Change in Use | Conveyance Tax |
|---|---|
| Year 1 | 10% of fair market value |
| Year 2 | 9% |
| Year 3 | 8% |
| Year 4 | 7% |
| Year 5 | 6% |
| Year 6 | 5% |
| Year 7 | 4% |
| Year 8 | 3% |
| Year 9 | 2% |
| Year 10 | 1% |
| After Year 10 | No penalty |
There's a second wrinkle that matters just as much. The Town of Willington explains that the classification is personal to the owner who applied for it. It does not run with the land. Once ownership changes, the classification ends, and a new owner has to file their own application and requalify from scratch. A buyer cannot simply assume the low tax bill they saw on the listing will follow them into ownership.
Builders and Subdividers Feel This First
For anyone buying Tolland land with an eye toward building or subdividing, this mechanism moves from background detail to front-and-center planning issue. State guidance has consistently treated the filing of an approved subdivision plan, or marketing lots for sale, as a change in use that ends PA 490 status on its own, separate from any actual sale.
That means a seller holding land under a farm or open space classification who agrees to sell to a builder, or who starts marketing lots themselves, can trigger the conveyance tax the moment that subdivision plan gets filed, even before a single lot changes hands. Anyone negotiating for raw acreage with development potential in Tolland should ask directly whether the parcel currently carries a PA 490 classification, how long it's held that status, and whether the seller has accounted for a possible conveyance tax in the number they're willing to accept. It affects what net proceeds actually look like on the seller's side, which in turn affects how much room there is to negotiate on price.
Not every large parcel on the market runs through this system. Some of Tolland's bigger land listings sit inside zones built for exactly the kind of development PA 490 discourages. A 30-plus-acre commercial parcel along Route 195, within the Tolland Technology Campus Zone and close to the University of Connecticut, already has sewer and water access at the street and is permitted for retail, hospitality, office, lab, and mixed-use development. That's a fundamentally different kind of large parcel, priced and positioned for building rather than preservation. Knowing which category a given piece of land falls into, before writing an offer, changes the entire financial picture.
The Window Closes October 31
Tolland completed its most recent revaluation for the 2024 Grand List, with new assessments effective October 1, 2024, according to the Tolland Assessor's Office. That means 2026 is a non-revaluation year for the town, and the Tolland Assessor's Office says first-time PA 490 applications for this classification cycle are due between September 1 and October 31. Anyone who owns qualifying farm, forest, or open space land in Tolland and hasn't yet filed has a real deadline sitting a few weeks away, not an abstract one.
For a buyer under contract on a large parcel right now, or a seller weighing whether to apply for classification before listing, this isn't a detail to research later. The filing window and the closing calendar can easily collide.
A Few Quick Answers
If I buy PA 490 land, do I automatically keep the lower tax assessment? No. The classification belongs to the owner who applied for it, not the land itself. A new owner has to file their own application with the town assessor to be considered for the same use-value treatment.
Does the conveyance tax apply to every sale of PA 490 land? It applies when the sale, transfer, or change in use happens within ten years of the land being classified. After ten years under classification, the penalty schedule reaches zero.
How do I find out if a specific Tolland property is currently classified under PA 490? The town assessor's office maintains this information, along with property record cards that show current classification status. It's a direct call worth making before an offer goes in on any parcel over an acre.
Acreage tells you almost nothing on its own in this market. What tells you something is what's actually written into the assessment, and that's a conversation worth having before you're standing at the closing table instead of before you write the offer.
