Timber Tax
Timber tax, done by a CPA who actually works with timber owners.
Basis, depletion, §631(a) and §631(b), §1033 casualty replacement, §194 reforestation, 1031 exchanges for timberland, and Oregon-specific rules — coordinated with the rest of your return, not treated as a bolt-on.
Timber Depth
The mechanics that matter for timber owners.
Descriptions below are general education, not advice. Specific tax positions depend on your facts and are confirmed in an engagement.
Timber basis
Cost allocated between land and standing timber at acquisition, stepped up at inheritance. Establish it once and you carry it forward across every harvest. Miss it and you overpay.
Depletion
Each cut recovers a slice of your basis in proportion to volume removed. Track it right and you deduct the cost of the wood, not just the operating expense.
§631(a) election
Cutting your own timber? A §631(a) election can split ordinary operating profit from capital-gain treatment on the standing-timber value. Powerful when done deliberately.
§631(b) sales
Selling standing timber with a retained economic interest — the pay-as-cut deal — gets §1231 treatment automatically. No election needed, but the mechanics have to be right on paper.
§1033 casualty replacement
Fire, storm, disease, or condemnation forces a sale — but the gain can be deferred if replacement property is acquired inside the §1033 window. For timber, that window is longer than most people realize.
§194 reforestation
Qualified reforestation costs get expensed up to a per-year limit, with the excess amortized. A recurring deduction that quietly compounds over the life of a working tract.
1031 for timberland
Timberland is real property. Rolling one tract into another via §1031 is on the table — with the same identification and replacement-window rules that trip up real-estate exchanges.
Oregon Forest Products Harvest Tax
Oregon assesses a per-thousand-board-feet tax on harvested timber, and special-assessment programs (Small Tract Forestland, Forestland Program) change the property-tax math. State side matters as much as federal.
Coordinated with the rest
Timber income lands next to your business, real-estate, and passive positions on the same return. Every decision here has to work with the rest of the picture.

Common questions
Timber tax, briefly answered.
Is a timber sale ordinary income or capital gain?
Both are possible, and the answer turns on how the timber leaves your hands. Selling standing timber with a retained economic interest generally falls under §631(b) as §1231 (capital-gain-eligible). Cutting timber you own and processing the wood yourself can qualify for §631(a) treatment on the standing value if you elect it — with ordinary income on the manufacturing/operating spread. Selling logs off the truck to a mill with no economic interest is typically ordinary. The characterization has to be built from the actual transaction structure.
I inherited timberland — how do I calculate my basis?
The land and standing timber usually take a stepped-up basis to fair market value as of the date of death. Establishing that value normally means a timber cruise (measured volume + species + condition) tied back to the valuation date, with the price data that supported it. Getting this right at inheritance means every future harvest recovers real basis, not a token amount. The video above walks through the mechanics.
Do 1031 exchanges work for timber?
Timberland is real property, so §1031 applies. Standing timber is generally treated as part of the underlying land. The usual §1031 rules — 45-day identification, 180-day replacement, qualified intermediary, no touching the proceeds — apply the same way as for a rental building. The place people get in trouble is treating cut logs or personal property riding along with the land as if they were part of the exchange.
My timber was destroyed by fire. Am I stuck with a giant tax bill?
Not necessarily. §1033 lets you defer gain from an involuntary conversion — including fire, storm, disease-forced salvage, and condemnation — if the proceeds are reinvested in similar-use property inside the replacement window. For timber the window is longer than the standard two years in many cases. Getting the election and the replacement documented properly is where §1033 either saves the day or falls apart.
Do I need a CPA in Oregon specifically for my timber?
If your tract is in Oregon, yes — the state-side rules (Forest Products Harvest Tax, Small Tract Forestland assessment, forestland deferrals) don’t run themselves, and generalist prep tends to miss them. If you’re out-of-state but face similar state-level programs, the underlying federal analysis is the same and the state work coordinates through applicable multistate practice rules.
