TL;DR
New Hampshire's current use formula values enrolled land by soil and land type category (set annually by the state Current Use Board), not by market value, then applies your town's tax rate to that lower figure. Rates for 2025 range roughly $19 to $425 per acre depending on category. Withdrawing land triggers a rollback tax equal to 10% of the land's full market value.
What is the NH current use tax formula, exactly?
New Hampshire's current use program taxes enrolled land based on its category value per acre, set by the state's Current Use Board, instead of what the parcel would sell for on the open market. The formula for your annual bill is simple once you know the inputs: category value per acre, multiplied by acres in that category, multiplied by your town's local tax rate (expressed per $1,000 of assessed value). So if you have 40 acres of unstocked forest land assessed at $125/acre (a real 2025 range figure, see below), your assessed value for that parcel is $5,000, not whatever 40 wooded acres would fetch from a buyer. Your town then applies its tax rate to that $5,000 figure just like it would to any other assessment. The legal basis is RSA 79-A, New Hampshire's Land Use Change Tax and current use statute. The law states its purpose plainly: to encourage "the preservation of open space" and to prevent farm and forest land from being "taxed at rates or assessments which reflect its highest and best use rather than its current use" [1]. The category values themselves aren't set by your assessor. They're recommended annually by the state Current Use Board and published in an official range, and each town's assessor picks a value within that range for each category, then applies it uniformly across the municipality.
What are the current use land categories and their per-acre values?
| Unimproved land, unstocked | ~$25-$85 | |
|---|---|---|
| Forest land, all grades combined | ~$25-$425 (varies heavily by soil grade) | |
| Farm land (cropland/pasture) | ~$35-$500+ | |
| Wetland | ~$19-$100 | |
| White pine, hardwood, etc. (by grade) | varies by soil productivity grade within forest category | These are approximate and change annually. The real numbers for the current tax year are published by the Department of Revenue Administration's Current Use Board and you should pull the current document rather than trust a static table anywhere online, including this one. Forest land is further broken down by soil grade, essentially how productive the land is for growing timber. Two 20-acre forest parcels in the same town can carry different per-acre values if their soils differ. There's also a "land unproductive" category for wet, rocky, or otherwise low-value acreage, which typically sits near the bottom of the range. Confirm exact current-year numbers with your county assessor before running any savings math. |
New Hampshire splits enrolled land into a handful of categories, each with its own value range set annually. The Board publishes minimum and maximum per-acre figures for each; assessors choose where in that range to land for their town, and most towns stick close to the same number year over year. Here's the general shape of the categories and approximate 2025 ranges, drawn from the Board's current use assessment range document: | Category | Approx. 2025 range ($/acre) |
How much can current use actually lower my tax bill?
The gap between current use value and market value is usually large, sometimes 80-95% lower per acre, but the real dollar savings depends entirely on your town's tax rate and your land's category. There's no single statewide savings percentage anyone can honestly quote you. Here's the mechanic: take your acreage in each category, multiply by that category's per-acre value, multiply by your local tax rate per $1,000, divide by 1,000. Compare that to what the same acreage would generate if assessed at full market rate. A rough illustration, not a promise: 50 acres of forest land assessed at $150/acre in current use is $7,500 in assessed value. The same 50 acres assessed as raw land at, say, $4,000/acre (regionally dependent) would be $200,000. At a $20 per $1,000 tax rate, that's the difference between a $150 annual bill and a $4,000 annual bill on that parcel alone. That's a real gap, and it's why current use enrollment matters so much for owners sitting on undeveloped acreage. Those numbers are illustrative, not a quote for your property. Actual market assessments vary enormously by county, road frontage, and development pressure. Confirm your town's actual tax rate and your parcel's actual market assessment with your county assessor before you enroll or model savings.
What is the Forest Management Bureau and does it set the formula?
New Hampshire doesn't have an agency literally named "Forest Management Bureau," but the phrase usually points readers toward the New Hampshire Division of Forests and Lands, part of the Department of Natural and Cultural Resources, which oversees state forestry policy, stewardship programs, and forest health [2]. Some other states do use "Forest Management Bureau" as an actual office name inside their state forestry agency, which causes confusion for people searching across states. The Division of Forests and Lands doesn't set current use values; that's the job of the Current Use Board under the Department of Revenue Administration. What the Division does handle is forest health, state forest management, the Good Forestry in the Granite State guidance, and support for landowners working with licensed foresters. If you're trying to figure out who actually administers your county's assessment, that's your local assessor's office. If you want guidance on writing or updating a forest management plan, that's the Division of Forests and Lands or a licensed consulting forester, not the tax board. For background on what a forest management plan actually contains and why lenders, buyers, and tax programs care about one, see forest management.
What is forest management, in the context of current use enrollment?
Forest management, for current use purposes, means the practice of overseeing a woodland parcel with documented goals: timber growth, wildlife habitat, water quality, or some blend of those, usually guided by a written plan. Most current use programs, including New Hampshire's, don't require an active harvest, just enrollment in the land use category and adherence to the rules that keep the parcel eligible. New Hampshire's minimum for current use enrollment is 10 contiguous acres per RSA 79-A:2, with smaller carve-outs and stacking rules for certain conservation-restricted or wetland parcels [1]. You don't need to be actively logging to qualify; unmanaged forest land generally still counts as "forest land" for category purposes, though some towns and the Board distinguish stocked vs. unstocked forest for valuation. A written forest management plan isn't always mandatory for basic current use enrollment in New Hampshire, but it becomes important if you're pursuing the additional 20% assessment reduction available for land enrolled with a certified "stewardship" designation, or if you want documentation ready for a future timber sale, cost basis calculation, or casualty loss claim. Plans are typically written by a licensed forester and should be updated roughly every 10 years to stay useful. If you're comparing forest management against timber management as terms, see timber management for how the two overlap and where they diverge.
What triggers the rollback tax and how is it calculated?
New Hampshire's Land Use Change Tax (LUCT), commonly called the rollback tax, applies when land enrolled in current use is developed, subdivided for development, or otherwise changed to a use that disqualifies it. The tax is 10% of the full, unrestricted market value of the land at the time of the change, not the current use value [1]. The statute is direct on this point: RSA 79-A:7 sets the land use change tax at "10 percent of the full and true value" of the land determined as if it were not in current use [1]. That's a one-time tax, assessed the year the change happens, and it's separate from your regular annual property tax. Important nuance: simply selling the land doesn't trigger rollback if the new owner keeps it in current use and the land use doesn't change. It's the *use change* (building a house, clearing for a subdivision, converting to a use that fails the category tests) that triggers it, not the transfer of ownership itself. Many buyers of current use land specifically continue enrollment to avoid triggering the tax at closing. Cutting timber, by itself, is generally not a disqualifying change under RSA 79-A as long as the land remains forest land afterward and isn't developed. That said, poor cutting practices or land clearing tied to a development plan can trigger scrutiny. If you're weighing a harvest against enrollment status, loop in a licensed forester and your assessor before, not after, cutting.
Do I have to pay taxes on timber sold from my land?
Yes. Income from a timber sale is generally taxable, but how it's taxed depends on whether the wood is standing timber sold under Section 631(a)/(b) treatment, ordinary income, or a casualty/involuntary conversion. The IRS and USDA Forest Service jointly publish guidance for timber sellers explaining that qualifying timber sale income may be reported as a capital gain if you've held the timber long enough and it qualifies, which often means a lower rate than ordinary income [3]. The general rule most landowners run into: if you owned the timber for investment or personal use (not as a dealer actively buying/selling timber as inventory) and held it more than a year, a lump-sum or pay-as-cut sale is typically eligible for long-term capital gains treatment. That's a meaningfully lower federal rate than ordinary income for most owners. New Hampshire does not have a state income tax on this type of capital gain, but it does apply a separate timber yield tax at the local level. Municipalities assess a tax on the stumpage value of timber cut, currently at a rate of 10% of stumpage value, collected at the town level when a timber tax report (Report of Cut) is filed with the town clerk's office. That's a distinct, timber-specific tax layered on top of any federal capital gains obligation, and it applies whether or not the land is enrolled in current use.
How are timber sales taxed at the federal level?
Federal treatment of a timber sale hinges on classification: is the timber a capital asset, and are you selling standing timber (Section 631(b)) or cutting it yourself and treating the cutting as a sale (Section 631(a))? Both routes can qualify for capital gains treatment, but the mechanics differ [4]. Under a lump-sum sale, you sell standing timber for a fixed price before it's cut; the buyer takes the cutting risk. Under pay-as-cut, you're paid based on actual volume harvested, which is the more common arrangement for most non-industrial landowners. The USDA/IRS joint guidance notes that gain on qualifying timber held long-term is taxed at the lower long-term capital gains rates rather than as ordinary income [3]. You'll need your timber basis (the portion of your original purchase price or inherited value allocated to standing timber, distinct from land basis) to calculate gain correctly. This is where a lot of owners overpay. Without an allocated timber basis established at purchase or inheritance, some people report the entire sale proceeds as gain, when in reality only the amount above your basis is taxable. For background on separating land basis from timber basis, see basis of land. Active timber businesses (dealers, or landowners who materially participate at a level the IRS treats as a trade or business) may have different reporting requirements, including Schedule C treatment for some income streams. This is genuinely complicated territory and a forestry-savvy CPA is the right place to get sale-specific advice, not a general article like this one.
How do I report a timber sale on my tax return?
Most non-industrial landowners report qualifying timber sale gains on IRS Form T (Forest Activities Schedule) when required, or via Form 8949 and Schedule D for capital gains, depending on sale type and whether Form T's filing threshold applies to you. The joint USDA Forest Service/IRS guidance is a direct primary source explaining which form applies to which situation [3]. Generally: a lump-sum or pay-as-cut sale of standing timber held long-term as an investment gets reported as a long-term capital gain on Schedule D, using Form 8949 to detail the sale, gain, and basis recovered. If you're cutting your own timber and electing Section 631(a) treatment (treating the cutting itself as a deemed sale, with fair market value on the first day of the tax year as your basis point), that's more involved and usually needs Form T [4]. Form T is required for many timber account holders, but the IRS has historically waived it for small, occasional sellers who aren't in the timber trade or business, based on de minimis guidance. The requirement and its exceptions have shifted over time, so check current Form T instructions before assuming you're exempt. At the state level in New Hampshire, remember the separate timber yield tax obligation: you (or your buyer, depending on your contract) generally need to file a Report of Cut with the town, and the 10% stumpage tax gets paid locally, independent of your federal income tax return.
How do I avoid or reduce capital gains tax on a timber sale?
You generally can't avoid tax on a profitable timber sale entirely, but you can legally reduce the taxable gain, and sometimes defer it, through a few well-established mechanics: accurate basis allocation, long-term holding for capital gains rates, and reforestation cost amortization. The single biggest lever most landowners miss is timber basis. If you never established a basis allocation between land and standing timber when you acquired the property, you may be paying tax on proceeds that should have been offset by basis. The IRS/Forest Service guidance specifically flags basis establishment as a step landowners should take as soon as possible after acquisition rather than waiting until a sale forces the issue [3]. Reforestation costs (site prep, seedlings, planting labor) up to $10,000 per year per qualified timber property can be expensed, with amounts above that amortized over 84 months, under IRC Section 194 [5]. That's a real, current provision, not a maybe. Beyond that: timing matters. Spreading a large harvest across two tax years, or structuring a sale to fall in a lower-income year, can meaningfully change your marginal rate exposure. None of this is a substitute for a CPA who's actually worked timber sales before; the rules interact with your overall income picture in ways a general article can't model for you.
Do current use enrollment and timber sale taxes interact at all?
Not directly on the income tax side, but they interact procedurally. Being enrolled in current use doesn't change your federal capital gains treatment on a timber sale, and it doesn't change New Hampshire's local timber yield tax, which applies to cut timber regardless of current use status. Where they do interact: if a timber harvest is part of a larger land conversion (say, clearing land to build), that combination can trigger the rollback tax discussed earlier, even though the cutting itself wouldn't have. Assessors sometimes look at heavy clearing as circumstantial evidence of a use change, especially near parcel boundaries or access roads being built wider than a logging operation needs. The practical move: if you're enrolled in current use and planning a harvest, tell your assessor's office ahead of time or at minimum file your Intent to Cut promptly, keep your forester's plan and any correspondence on file, and don't clear land beyond what the harvest plan calls for. That paper trail matters if your rollback status ever gets questioned. Getting the current use enrollment paperwork, the forest management plan requirements, and the timber tax reporting steps organized in one place before you need any of them is exactly the kind of prep work that avoids scrambling later. That's the gap our $149 one-time Current-Use Enrollment & Compliance Kit is built to close. It's a document and checklist system, not tax advice, and it's built around the engagement you'll have with a licensed forester and your county assessor, not a replacement for either.
What should I actually do before enrolling in NH current use?
Start with your county assessor's office, not a search engine. Ask for your town's current per-acre values by category (forest, farm, unstocked, wetland) for the current tax year, and ask what your parcel's market value assessment is today so you can compare the two honestly. Next, get boots on the ground with a licensed forester if you don't already have a relationship. Even though a written management plan isn't universally mandatory for basic RSA 79-A enrollment, it's the foundation for the 20% stewardship discount, for future timber basis documentation, and for defending your land's category if it's ever questioned. Then file the current use application (Form A-10 in New Hampshire) with your assessor by April 15 for that tax year, keeping in mind that late applications generally roll to the following tax year [1]. Confirm the exact deadline and required forms with your assessor, since municipal processing details can vary slightly. Finally, before any harvest, get your Intent to Cut filed with the town and understand the 10% timber yield tax obligation so it's not a surprise at settlement. None of this replaces a conversation with your own CPA or a licensed forester, but having the checklist, the deadlines, and the right document names in hand before you walk into the assessor's office saves a lot of back-and-forth.

Frequently asked questions
What is the Forest Management Bureau in New Hampshire?
New Hampshire doesn't have an office literally named the Forest Management Bureau; the closest match is the Division of Forests and Lands under the Department of Natural and Cultural Resources, which handles forest health and stewardship policy. Current use values are actually set separately by the Current Use Board under the Department of Revenue Administration.
What is forest management?
Forest management is the practice of overseeing woodland for defined goals like timber growth, wildlife habitat, or water quality, usually guided by a written plan from a licensed forester. It doesn't require active logging; unmanaged forest land typically still qualifies for current use enrollment in New Hampshire.
How do I report the sale of timber on my tax return?
Long-term timber sales usually go on Schedule D and Form 8949 as capital gains, with Form T (Forest Activities Schedule) required in some cases involving deemed sales under Section 631(a). The IRS/USDA joint guidance for timber sellers is the clearest primary source for matching your sale type to the right form.
How do I avoid capital gains tax on a timber sale?
You generally can't avoid it entirely on a profitable sale, but you can reduce taxable gain by properly allocating timber basis, holding long-term for capital gains rates, expensing reforestation costs (up to $10,000/year under IRC Section 194), and timing the sale across tax years if income allows.
Do I have to pay taxes on timber sold from my land?
Yes, timber sale income is generally taxable at the federal level, often as a capital gain if you held the timber as an investment for more than a year. New Hampshire also imposes a separate 10% local timber yield tax on stumpage value, regardless of federal treatment.
Do you have to pay taxes on timber sales in New Hampshire specifically?
Yes. Even though New Hampshire has no broad personal income tax, it applies a 10% timber yield tax on stumpage value at the town level, filed via a Report of Cut. Federal capital gains tax on the sale still applies separately.
How are timber sales taxed, federal versus state?
Federally, qualifying timber held long-term is taxed as a capital gain, generally at lower rates than ordinary income. In New Hampshire, there's also a local 10% timber yield tax on stumpage value, which is unrelated to income tax and applies at the town level when timber is cut.
What is New Hampshire's current use tax formula in simple terms?
Take your land's category value per acre (set annually by the state Current Use Board, roughly $19 to $425 depending on category for 2025), multiply by your acreage in that category, then apply your town's local tax rate per $1,000 of assessed value. That's your annual current use property tax.
What triggers the New Hampshire rollback tax?
The Land Use Change Tax triggers when enrolled land is developed, subdivided, or otherwise converted to a use that disqualifies it from current use, per RSA 79-A:7. It's calculated as 10% of the land's full market value at the time of the change, not the lower current use value.
How much acreage do I need to qualify for NH current use?
New Hampshire generally requires 10 contiguous acres minimum under RSA 79-A:2, with some exceptions for certain wetland or conservation-restricted parcels that can qualify with less. Confirm your parcel's exact eligibility with your county assessor since local application varies.
Does selling land enrolled in current use trigger the rollback tax?
Not by itself. Rollback tax triggers when land use changes, not when ownership transfers. If a new owner keeps the land in current use with no disqualifying change, the 10% Land Use Change Tax under RSA 79-A:7 is not triggered by the sale.
Does cutting timber disqualify land from NH current use?
Generally no, as long as the land remains forest land after the harvest and isn't cleared for development. Poor practices or clearing tied to a development plan can raise assessor scrutiny, so confirm your harvest plan with a licensed forester and file your Intent to Cut before cutting.
What's the difference between current use value and market value in NH?
Current use value is a fixed per-acre figure set annually by category (forest, farm, wetland, unstocked) by the state Current Use Board, unrelated to what land would sell for. Market value reflects highest-and-best-use potential, like buildable or recreational value, and is typically far higher per acre.
