What Is Timber Basis, and Why It Matters If You Inherited the Land

Somebody died and left you land with trees on it. Now a person you barely know has used the word "basis" at you, like you should have been born knowing it.

Basis is the tax value of your timber. When you sell, tax is figured on the sale price minus your basis, not on the whole check. Timber you inherit generally gets a fresh basis equal to what it was worth on the day the person died, under 26 U.S.C. 1014(a)(1). Forty years of their growth stops being taxable to you.

Nobody calculates that number for you. If you cannot document a basis, you cannot claim one.

What does "basis" mean in plain English?

Mississippi State Extension's publication P1983 defines it in one line: "Basis is the book value of property." It is what the property counts as costing you, for tax purposes only. It has nothing to do with what the county says your land is worth, or what a buyer offered last week.

Buy timberland and your basis in the timber is the share of the purchase price that belongs to the trees. Inherit it and the rule changes, and the change is worth money.

Why does inherited timber get a fresh start?

Because the tax code says so. Under 26 U.S.C. 1014(a)(1), property acquired from a person who died takes a basis equal to its fair market value on the date of death. The USDA Forest Service repeats it in landowner language in Tax Tips for Forest Landowners, publication FS-1275, dated January 2026: "If you inherited it, the original timber basis generally is its FMV on the deceased person's date of death."

Think about what that does to a stand your grandfather planted. He had almost no basis in it. He never bought those trees; he bought seedlings and time. Had he sold the timber himself, nearly the whole check would have been taxable gain. You inherited instead, and your basis restarts at what a willing buyer would have paid for that standing timber the week he died. Sell soon after, at close to that value, and there may be very little gain left to tax.

Very little is not none. Timber keeps growing and prices move, so gain builds again from the date of death forward. Anyone telling you basis always wipes out the tax is guessing.

A second gift is buried in the same rule. FS-1275 (January 2026) states that "If you inherited timber, you are considered to have held the property longer than 1 year, regardless of how long you actually held it." The same publication says income from standing timber held more than one year qualifies for long-term capital gains rates of 0, 15 or 20 percent depending on your taxable income, rather than ordinary income rates. Inherited timber clears that hurdle on day one, even if you sell three months after the funeral.

Which date matters, and what if it was years ago?

The date of death. That is the default and it is the one almost every heir will use.

There is one alternative. Under 26 U.S.C. 2032, an estate may elect to value everything six months after the date of death instead. Section 2032(c) allows that election only if it decreases both the value of the gross estate and the estate tax owed, so it comes up only on estates large enough to file a federal estate tax return. If nobody filed one, your date is the date of death.

North Carolina will not send a state estate tax bill either way. G.S. 105-32.1 through 105-32.8 were repealed by Session Laws 2013-316, s. 7(a), effective January 1, 2013, applicable to estates of decedents dying on or after that date. Good news that sets a trap: when no estate tax return has to be filed, no appraiser walks the property and no number gets written down. Ten years later you go to sell timber and the file is empty.

Can you still establish basis after the fact?

Often, yes. The work has a name, a retroactive basis appraisal, and a forester can do it years after the funeral.

Purdue Extension's FNR-FAQ-2, Determining Tax Basis of Timber, by William L. Hoover, gives the mechanics: the law allows "the basis determination to be made some time after the date of acquisition," but "the determination must be based on conditions on the date of acquisition." The same publication says a forester gets there by growing "the timber in reverse," using the volume standing today and the growth rate to work back to the date you acquired it.

University of New Hampshire Extension, in its documentation for the Timber Basis Decision Model, adds the caution: "If they are not done at that time, they can be done retroactively. Retroactive appraisals are often more complex and costly." The same document describes the method. A forester "can use an established practice to calculate growth during the intervening years to determine timber volume and use historical stumpage value information to assign a timber value for the year when the property was acquired."

Two halves to the job. How much wood was standing on the date of death, and what it was worth then. A consulting forester measures the stand now, backs the growth out, and pairs that volume with stumpage prices published back then. For the vocabulary before you sit down with one, read what stumpage value is.

Establish and document your basis before or at the time you sell. Do not sell first and build a number afterward to fit the tax bill. The determination has to rest on conditions at the date of death, and the thinner the evidence gets, the harder that is to stand behind.

Two cautions. Retroactive work costs money, and no published North Carolina figure says how much. It turns on tract size, how far back you are reaching and how much is left to measure, so ask two consulting foresters for a written quote. And it does not always pay. UNH built its Timber Basis Decision Model, at extension.unh.edu/timber-basis, for that exact question: does the tax saved beat the cost of the appraisals. On a small tract with modest volume, the answer can be no.

How does the value get split between land and timber?

An estate appraisal usually produces one number for the whole property. That number has to be broken apart. Land is not depletable. Timber is.

The National Timber Tax rule is proportional. "The stepped-up basis allocated to the timberland must be further allocated to the land and the merchantable timber. This is done in proportion to the amount of total fair market value attributable to the land and the timber." Their example: if merchantable timber made up 60 percent of the total fair market value on the date of death, 60 percent of the stepped-up basis goes into the timber account.

So a general real estate appraisal is not enough by itself. A residential appraiser can tell you what 80 acres in your county sold for. Only a measured estimate of the standing timber, called a timber cruise, says what share of that value was in the trees. How to sell timber on your land covers where a cruise fits in a sale.

What is depletion, and how does it lower my tax?

Depletion is how you spend the basis you went to the trouble of establishing. FS-1275 (January 2026) describes it as the recovery of a portion of your timber basis when timber is cut, sold on the stump, or lost.

The arithmetic is a rate per unit. Divide the basis in a timber account by the volume in that account. That is your depletion unit. Multiply it by the volume you sell, and the product comes off the sale proceeds before tax.

Example 6 in FS-1275 (January 2026): an owner has 1,000 tons of sawtimber with a $10,000 basis and 6,000 tons of pulpwood with a $6,000 basis. The depletion units are $10 per ton and $1 per ton. Sell 500 tons of sawtimber and 3,000 tons of pulpwood, and the allowable basis for that sale is $8,000.

Notice that sawtimber and pulpwood are tracked separately. Two products at two values on the same truck. Lump them together and your depletion comes out wrong.

One limit, same publication: "timber depletion is not allowed for timber cut for your personal uses, such as firewood for your home."

What records do I need, and how long do I keep them?

Keep it as long as you own the land. Basis is not a one-time filing. It sits in your records until the last stick is sold. What matters:

• The estate paperwork. In North Carolina, G.S. 28A-20-1 requires the personal representative to return "a just, true and perfect inventory of all the real and personal property of the deceased" to the clerk of superior court, generally within three months of qualifying. That inventory is a public record in the county where the estate was administered, and it is the first place to look for a date-of-death value.
• Any appraisal that already exists. Bank, estate, farm loan. Even a general one helps anchor the land side.
• The date of death itself. The certificate, not somebody's memory.
• The forester's basis report, with the cruise data, the growth assumptions, the stumpage prices used, and the date it was prepared.
• Separate accounts for land and timber. Mississippi State's P1983 is blunt: keep separate land and timber accounts and retain adequate records to support a claim of basis recovery.
• Every sale afterward, with volumes by product, so you can subtract what you have already depleted.

Then there is IRS Form T (Timber), Forest Activities Schedule, current revision December 2013 on irs.gov. FS-1275 (January 2026) says you must file it if you claim a timber depletion deduction, though it "is not required if you only have occasional timber sales (one or two sales every 3 or 4 years)." Even then, "you need to maintain adequate records of these transactions."

Who can do this for me?

Two people, and they are not the same person.

A consulting forester measures the timber and produces the basis report. The N.C. Forest Service publishes a statewide list of consulting foresters at ncagr.gov, and any NCFS county ranger can point you to it. It is a published list, and nobody on it has been checked out for you. Ask for a registration number, confirm it yourself, and see whether you need a forestry consultant.

A tax preparer, CPA or enrolled agent puts those numbers in the right places on the return. Ask whether they have handled a timber sale before. Many have not. No shame in either direction, but you want to know before April.

Your timber buyer is neither of them. TimberClear lists timber businesses and routes introductions. We have not vetted, verified or endorsed anybody on this site. Nothing here is tax advice.

Two documents to put your hands on

Pull the estate file. Go to the clerk of superior court in the county where the estate was administered, or call and ask how to request a copy, and get the inventory filed under G.S. 28A-20-1. Write down the date of death and any value listed for the land.

Then get a written quote. Call a consulting forester, give them the date of death and the acreage, and ask what it would cost to establish a timber basis as of that date and whether there is enough timber here to make it worth doing. A forester who says it is not worth doing has answered the question you were paying to ask.

Do that before you sign anything with a buyer. If a sale is already moving, read how to sell timber on your land first. If your land is enrolled in the state's forestry property tax program, read selling timber and present-use value before the equipment shows up.
