There is tax on lumber at nearly every stage between the forest and the finished wall. Retail buyers pay state and local sales tax in about 45 states, with combined rates running from roughly 4% to over 11%. Timber owners who sell wood owe federal income tax and, in many states, a severance tax on the harvest itself. Foreign lumber carries import duties that stacked heavily higher in 2025 and 2026. The rules that apply to you depend on whether you are buying boards, cutting trees, or bringing wood across the border.
Sales Tax at the Lumberyard
Buy dimensional boards, plywood, or other wood products at a retail store or lumberyard, and the receipt includes sales tax in most states. Five states charge no statewide sales tax at all. Everywhere else, the rate combines the state’s base rate with any county, city, or special district add-ons. The combined rate can be as low as about 4% or higher than 11%.
Most states use destination-based sourcing. The rate is set by where the lumber is delivered, not where the seller sits. A contractor ordering wood shipped to a project in another county or state pays the rate at the delivery address, and the seller has to collect it. Getting the rate wrong creates audit exposure for the vendor.
Sales tax is calculated on the full purchase price, including processing or handling fees. Failing to collect or remit correctly can bring late-payment penalties, interest, and in serious cases criminal liability or loss of a business license.
Use Tax on Out-of-State and Online Lumber Purchases
Ordering lumber from an out-of-state supplier or an online retailer that did not charge your state’s tax does not end the tax obligation. Use tax fills the gap. It applies at the same rate as your local sales tax and covers any taxable purchase where the seller failed to collect the right amount. The buyer has to report and pay it.
Businesses report use tax on their regular sales tax returns. If you paid some tax to the seller at a lower rate than your home jurisdiction charges, you owe the difference. The tax applies to the full delivered cost, shipping and handling included. Individuals typically report use tax on their annual state income tax return, though individual compliance rates are notoriously low.
This matters more for lumber than for many other goods because contractors and builders often source materials from wherever the price is best. Invoices and delivery records make the purchases easy for an auditor to trace.
Exemptions That Remove Sales Tax on Lumber
Not every lumber purchase triggers tax. The most common exemption applies to businesses buying wood to resell or build into a product for sale. A cabinet shop buying boards to make furniture, or a homebuilder buying framing for a spec house, presents a resale certificate and skips the tax. The obligation shifts to whoever buys the finished product.
Agricultural operations often qualify when lumber goes into farming infrastructure like fencing, barns, or equipment shelters. Nonprofit organizations with federal tax-exempt status can also avoid sales tax on lumber for building projects in many jurisdictions. In every case, the buyer has to give the seller the proper certificate at or before the transaction. Without the paperwork, the seller must charge the full rate, and the records are the first thing an auditor will ask for.
Federal Income Tax on Timber and Lumber Sales
Sell timber you own and the proceeds are subject to federal income tax. How the gain is classified changes what you owe. Two provisions in the tax code let timber owners shift what would otherwise be ordinary income into capital gains, where the maximum federal rate tops out at 20% rather than the 37% ceiling on ordinary income.
Under Section 631(a), a timber owner who cuts standing timber for sale or for use in a trade or business can elect to treat the cutting as a sale. The gain equals the difference between the timber’s fair market value on the first day of the tax year and the owner’s adjusted basis for depletion. The election is binding once made and applies to all timber the taxpayer owns or has a contract right to cut.1Office of the Law Revision Counsel. 26 USC 631 – Gain or Loss in the Case of Timber, Coal, or Domestic Iron Ore
Section 631(b) covers a different situation. When the owner disposes of standing timber under a contract but retains an economic interest, or makes an outright sale, the difference between the amount realized and the adjusted depletion basis is treated as a gain on sale. It qualifies for capital gains rates as long as the timber was held more than one year.1Office of the Law Revision Counsel. 26 USC 631 – Gain or Loss in the Case of Timber, Coal, or Domestic Iron Ore
Timber held as inventory does not get these benefits. A sawmill or lumber retailer reports profits as ordinary business income at standard corporate or individual rates. Misclassifying timber income can trigger the IRS accuracy-related penalty of 20% on the underpayment.2Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
Depletion Deduction
Timber owners do not pay tax on the full sale price. The depletion deduction recovers the original cost of the timber as it is harvested, similar to depreciation on a building. Claiming it requires establishing a cost basis at acquisition, which usually means a timber inventory or professional cruise to estimate merchantable volume.
Divide your adjusted basis by the total estimated volume in the account and you get a per-unit depletion rate. Multiply that rate by the volume harvested or sold during the year to get the deduction, which reduces your taxable gain. Timber owners report these figures on IRS Form T and maintain separate timber accounts with maps, acquisition dates, and valuation records.3Internal Revenue Service. Instructions for Form T (Timber)
Passive Activity Limits
Timber losses cannot always offset other income. Under Section 469, if you own timberland but do not materially participate in the operation, losses are passive and can only offset other passive income. The most direct way to meet material participation is 500 hours of involvement during the tax year. Reviewing financial statements from a distance does not count. Spouses can combine hours toward the threshold.4Office of the Law Revision Counsel. 26 USC 469 – Passive Activity Losses and Credits Limited
State Severance Tax on Harvesting
Harvesting timber triggers a separate state-level tax in many jurisdictions, commonly called a severance tax. Unlike sales tax, it targets the extraction of the resource rather than a retail transaction. The tax is calculated after the timber is cut, based on volume harvested (board feet, cords, or tons) or as a percentage of stumpage value.5U.S. Department of Agriculture. Current Status and Trends in Timber Severance Tax Legislation in the South
Rates vary widely. Some states impose a flat dollar amount per thousand board feet. Others charge a percentage of the timber’s value that can reach 6% or more. A handful of states have no severance tax. Severance tax operates independently from property tax and income tax, so a single harvest can generate three separate tax obligations in one year. Landowners typically file specialized returns after logging concludes, and late filings carry penalties.
Reforestation Deduction After a Harvest
The tax code offers an offset for owners who replant. Under Section 194, you can immediately expense up to $10,000 per year in reforestation costs for each qualified timber property. The limit drops to $5,000 for married individuals filing separately, and trusts cannot use the immediate deduction at all.6Office of the Law Revision Counsel. 26 USC 194 – Treatment of Reforestation Expenditures
Spending above the $10,000 threshold is amortized over 84 months, starting in the second half of the tax year the costs were incurred. Qualifying expenses include site preparation, seeds, seedlings, and labor for planting. The election is made on the return for the year the expenditures are paid or incurred.
Import Duties on Foreign Lumber
Foreign lumber carries some of the heaviest tax on the supply chain, and 2026 is a particularly expensive year. Three layers of duties can stack, and all of them get passed through to buyers.
Section 232 Tariff
A 10% tariff on softwood timber and lumber took effect on October 14, 2025, under a presidential proclamation invoking national security authority. The rate applies globally, not only to traditional trade dispute partners.7The White House. Adjusting Imports of Timber, Lumber, and Their Derivative Products Into the United States
Anti-Dumping and Countervailing Duties on Canadian Softwood
Canadian softwood lumber has been subject to both anti-dumping and countervailing duties for years. The combined rate has been running around 35% but is expected to drop to roughly 25% once the U.S. Department of Commerce finalizes its seventh administrative review later in 2026. Preliminary rates announced in April 2026 set the combined duty for most Canadian exporters at approximately 24.83%.8Global Affairs Canada. Softwood Lumber
Stacked on top of the 10% Section 232 tariff, total duties on Canadian softwood can exceed 35% of the declared value. The importer pays at the border, and the cost works into the price at every lumberyard and home center.8Global Affairs Canada. Softwood Lumber
End of the De Minimis Exemption
Small lumber shipments no longer slip in duty-free. The $800 de minimis threshold that previously allowed low-value imports to bypass formal customs entry was suspended effective August 29, 2025. All imported goods, regardless of value, now face full duty assessment, customs entry requirements, and applicable tariffs.9U.S. Customs and Border Protection. Suspending Duty-Free De Minimis Treatment for All Countries
Tax Relief After a Timber Casualty
When timber is destroyed by fire, storm, insects, or other disasters, the tax code provides two forms of relief. A casualty loss deduction lets you deduct the reduction in the timber’s fair market value caused by the event. Timber casualty losses are reported on Form 4684 and require a valuation of the affected property both before and after the loss.10Internal Revenue Service. Timber Casualty Loss Audit Technique Guide
If insurance proceeds or salvage revenue exceed your basis in the destroyed timber, Section 1033 lets you defer the resulting gain by reinvesting into replacement timber property within two years after the close of the first tax year in which the gain is realized. For condemned real property the window is three years, and for losses caused by a federally declared disaster it is four.11Office of the Law Revision Counsel. 26 USC 1033 – Involuntary Conversions
The replacement must be similar or related in service or use to what was destroyed. Reinvesting timber proceeds into timberland qualifies. Putting the money into a rental property generally would not. The deferred gain reduces your basis in the replacement property, which creates a future tax bill when that property is eventually sold.
