3.4 Current-Use Taxation, Subdivision & Site Conditions (RSA 79-A)

Current-use taxation — RSA 79-A

New Hampshire funds town and school budgets almost entirely through local property tax (there is no broad income or sales tax). To keep that tax from forcing the development of farms and woodlands, the legislature created current-use assessment under RSA 79-A. Land enrolled in current use is taxed on its value in its current open-space use — what it earns as farm or forest — rather than on its highest-and-best (market/development) value.

What qualifies

A parcel generally qualifies for current use if it is at least 10 acres of:

• Farmland, forest land, or unproductive land; or
• Land producing at least $2,500 in annual agricultural or horticultural products (which can qualify a parcel under 10 acres).

Enrollment is filed with the town and runs with the land — a buyer who purchases enrolled land takes it still in current use unless and until the use changes.

The Land Use Change Tax (RSA 79-A:7)

The critical exam fact: enrolling saves taxes now, but converting the land to a developed (non-qualifying) use triggers a one-time Land Use Change Tax (LUCT) equal to 10% of the full and true (market) value of the changed portion at the time of the change. Key points the exam tests:

• The LUCT is not "back taxes." It is a flat 10% of current market value of only the portion taken out of current use.
• Only the changed portion is removed; the rest can remain in current use if it still meets the criteria (e.g., is still 10+ acres).
• You can often sell or subdivide without triggering the tax as long as the resulting parcels still qualify.

Disclosure angle: If a listing is enrolled in current use, the buyer should be told that building on it will trigger the 10% LUCT. A buyer who plans to develop must budget for that one-time tax on top of the purchase price.

Water, septic, and subdivision — why acreage is not buildability

Most of New Hampshire is rural and not served by municipal water or sewer. A typical NH transaction therefore turns on three private-site questions that the state exam expects an agent to flag.

Private wells

Outside town water districts, drinking water comes from a private well (usually drilled bedrock). Because NH bedrock can carry naturally occurring arsenic, radon, and uranium, well-water testing is a routine buyer contingency — and the seller's RSA 477:4-a/4-d disclosures (covered earlier) ask about the water supply. An agent should never assert water is "fine" without test results.

Septic (subsurface disposal) systems

With no public sewer, wastewater is handled by an on-site septic system. Septic systems are designed, permitted, and approved through the New Hampshire Department of Environmental Services (NHDES) Subsurface Systems Bureau. Two NHDES-related facts matter at the closing table:

1. A property must have an approved system sized for the home; an undersized or failed system can block a sale or financing.
2. New construction and many lot subdivisions require NHDES subdivision/septic approval before lots can be built on.

Local subdivision and land-use control

Whether a parcel can actually be subdivided or built is decided locally, not by the state. Under RSA 674 and RSA 676, the municipal planning board adopts and applies subdivision and site-plan regulations, and the zoning board of adjustment hears variances and special exceptions.

Exam takeaway: Buildability is a local determination layered on top of state environmental approvals. A 20-acre rural parcel may still be unbuildable if the soils fail septic design or zoning blocks the use. Never represent that land "can be developed" based on lot size alone.

Practical agent duties on rural and conservation land

New Hampshire's rural inventory means agents constantly list parcels that carry current-use enrollment, conservation restrictions, or simply challenging soils and access. Each one changes what you can honestly promise a buyer.

Conservation easements and restrictions

Some open land is permanently restricted by a recorded conservation easement held by a land trust or the town. Unlike current-use (which is reversible at the cost of the 10% change tax), a conservation easement is generally permanent and bars development outright. An agent must read the recorded easement and disclose it; representing protected land as a future house lot is a misrepresentation. The exam contrast to know: current use is a tax classification that can be changed (with a tax), while a conservation easement is a permanent restriction on the title.

Reading the tax card

Because NH towns reassess and apply differing tax rates and equalization ratios, the property's tax card (assessment record) is a routine due-diligence document. An agent should help a buyer understand that the listed assessed value is not the market value and that buying a parcel out of current use will both raise the annual assessment to market value going forward and trigger the one-time 10% Land Use Change Tax on conversion. Quoting a buyer the seller's current low "current-use" tax bill without that caveat sets up a complaint.

Access, frontage, and lot-of-record questions

Finally, rural buildability often turns on legal access (a deeded right-of-way or adequate road frontage) and whether a parcel is a recognized lot of record. A landlocked parcel, or one that fails the town's minimum frontage, may be unbuildable regardless of acreage or soils. The agent's safe posture across all of these issues is the same: verify with the town and NHDES, disclose what the records show, and never assume buildability from lot size.
