Oregon, California, and Washington each tax a timber harvest differently, not the land sale itself, according to each state’s own revenue agency. Oregon charges a per-thousand-board-foot harvest tax, plus a separate severance tax for Small Tract Forestland enrollees. California charges a flat 2.9% of a state-set harvest value. Washington charges 5% of stumpage value, split between the county and the state.
How does Oregon tax timber after a harvest?
Oregon uses two layers of tax that apply to different owners. Every commercial timber harvest in the state, except most tribal land, owes the Forest Products Harvest Tax (FPHT), and landowners enrolled in the Small Tract Forestland (STF) Program owe an additional severance tax on top of it.
The FPHT applies per thousand board feet (MBF) of logs scaled at utility grade or better, plus certain chip loads, and the first 25,000 board feet harvested by an owner in a year is excluded from the tax, according to the Oregon Department of Revenue. Owners must still file a harvest return even when the volume falls under that threshold and no tax is due. Returns are due April 15 of the year after the harvest, with a 5% penalty for returns filed between April 16 and July 15, and a 25% penalty after that. Anyone whose estimated annual tax exceeds $1,500 has to make quarterly payments during the year.
The STF severance tax is a separate, additional charge that only applies to land classified under the Small Tract Forestland Program, parcels of 10 to 4,999 acres where the owner elected specially assessed forestland status. It exists because Oregon’s 1993 legislature decided standing timber on small tracts should be taxed more like a crop at harvest than as real property year over year, according to the Oregon Department of Revenue’s STF severance tax page. Under ORS 321.726, the base severance tax rate is $3.89 per MBF for timber harvested in western Oregon and $3.03 per MBF in eastern Oregon, with both figures indexed annually against changes in the average assessed value of small tract forestland in each region. Logs scaled below utility grade are exempt from the severance tax the same way they’re exempt from the FPHT. Revenue from the STF severance tax goes to the State School Fund, the Community College Support Fund, and participating counties, while FPHT revenue funds forest practices regulation and forestry research instead.
How does California’s timber yield tax work?
California taxes timber at a flat 2.9% rate, but the base it applies to is not what the timber actually sold for. The California Department of Tax and Fee Administration (CDTFA) sets an “immediate harvest value” schedule twice a year, broken out by species, log grade, and region, using evidence of stump-sale prices and adjusted log or product sale prices, according to CDTFA’s Timber Yield Tax guide. A harvester’s tax bill is 2.9% of the volume harvested multiplied by that schedule value, not by the price actually negotiated with a mill or logger.
The tax is filed quarterly, due the last day of the month following the end of each quarter, except Christmas tree growers who file only in the fourth quarter. Harvests with a total immediate harvest value of $3,000 or less in a quarter don’t need to register with CDTFA or file, per the agency’s Getting Started guide. Because the schedule resets twice a year, a harvest that straddles a schedule change can be taxed at two different per-unit values depending on which half it falls in. Unlike Oregon and Washington, California still taxes timberland itself every year through the regular county property tax roll: the yield tax at harvest is an additional, separate charge, not a replacement for property tax on the land.
How does Washington tax timber after a harvest?
Washington charges a single, flat 5% excise tax on the stumpage value of harvested timber, with no separate small-tract tier. Stumpage value is the estimated value of the timber as it stood before cutting, calculated from quarterly stumpage value tables the Washington Department of Revenue publishes by species, log grade, harvest type, and geographic stumpage value area, according to the department’s forest tax page. The tax revenue splits 4 percentage points to the county where the harvest took place and 1 percentage point to the state general fund.
The tax is due one month after each calendar quarter ends (April 30, July 31, October 31, and January 31) and can be filed online or by paper form. Washington eliminated the property tax on standing timber back in 1971 and replaced it entirely with this harvest-triggered excise tax, so unlike California, there is no ongoing annual tax on standing timber value between harvests. Most private harvests also require a Washington Department of Natural Resources permit before cutting begins, which is a separate process from the tax filing itself.
How do the three systems compare side by side?
| Oregon | California | Washington | |
|---|---|---|---|
| Tax name(s) | Forest Products Harvest Tax + STF severance tax (if enrolled) | Timber Yield Tax | Forest excise tax |
| Administering agency | Oregon Department of Revenue | California Dept. of Tax and Fee Administration | Washington Department of Revenue |
| What it’s based on | Board feet harvested (flat per-MBF rate) | State-set “immediate harvest value” schedule | State-calculated stumpage value |
| Rate | Per-MBF rate set annually; STF severance $3.89/MBF (west) or $3.03/MBF (east) base, indexed yearly | 2.9% of harvest value | 5% of stumpage value (4% county + 1% state) |
| Small-harvest exemption | First 25,000 board feet/owner/year | Quarters with $3,000 or less total harvest value | None published |
| Filing frequency | Annual, quarterly if tax exceeds $1,500 | Quarterly | Quarterly |
| Separate annual property tax on standing timber? | No (removed for STF land in 1993) | Yes, timberland is taxed annually in addition to the yield tax | No (removed in 1971) |
Who actually owes the tax: the seller or the buyer?
This is the detail that matters most for a landowner deciding whether to log before selling. In all three states, the harvest tax attaches to whoever owns the timber at the moment it’s cut, not whoever owned the land when it last changed hands. Washington’s rule is explicit on this point: the taxpayer is “the owner of the timber at the time of harvest,” according to the Washington Department of Revenue, and Oregon and California apply the same logic: the FPHT, STF severance tax, and timber yield tax are all triggered by the act of cutting, not by a deed transfer.
That means a landowner who sells timberland with the trees still standing passes the future tax liability to the buyer, along with the value of the timber itself. A landowner who logs the tract first and then sells the cutover land keeps the timber’s value but also absorbs the severance or yield tax personally, on top of logging costs, before whatever is left flows into the land sale. Deciding which order makes sense depends on the timber’s maturity, the buyer pool for cutover versus standing-timber land, and how the seller values a faster closing against a larger up-front logging project. A seller weighing that tradeoff on Oregon, California, or Washington timberland can also compare it against selling the parcel as-is; AMM Land Sales makes cash offers on timberland in its current condition, standing timber included, in states such as Oregon, California, and Washington.
What does this mean for a seller’s net proceeds after a harvest?
Net proceeds from a harvest are the sale price of the logs minus logging and hauling costs, minus the state severance or yield tax, minus any federal income tax on the timber sale, and the state layer alone varies enough between these three states to change the outcome meaningfully. A Washington harvest owes a flat 5% of calculated stumpage value regardless of how the sale was structured. A California harvest owes 2.9% of a schedule value that may not match the actual sale price, which can work in a seller’s favor when market prices run above the schedule, or against them when the reverse is true. An Oregon harvest on Small Tract Forestland land owes both the flat per-MBF FPHT and the separate per-MBF STF severance tax, which is a fixed dollar amount per thousand board feet regardless of what species or grade drove the actual price.
None of these state taxes account for the landowner’s cost basis in the timber, unlike the federal capital gains treatment that applies separately to timber income. A seller trying to estimate net proceeds before committing to a harvest needs the state tax calculation, the logging contractor’s cost quote, and a federal tax projection as three separate line items, not one combined guess. Because the STF severance tax rate and California’s harvest value schedule both reset periodically, the numbers that applied to a neighbor’s harvest two years ago aren’t a reliable stand-in for what a harvest today would owe. Landowners weighing whether the after-tax number from a harvest actually beats selling the land intact can find general background in AMM Land Sales’ land-type guides before deciding which direction to take a specific parcel.
The mechanics matter more than the headline rate once actual volume gets involved. A 100 MBF harvest on Oregon Small Tract Forestland land in the western part of the state owes the FPHT on top of a severance tax figured at roughly $389, using the $3.89-per-MBF base rate set in ORS 321.726 before that year’s index adjustment, a fixed dollar amount that doesn’t move whether the logs sold for a strong or weak price that quarter. The same volume in Washington owes 5% of whatever the state’s stumpage value tables say that species and grade were worth in that stumpage area, which does move with market conditions because the tables are updated quarterly. A California harvest of the same size owes 2.9% of the semiannual harvest value schedule, which can run above or below the actual contract price depending on when in the six-month cycle the logging happens. None of these are the seller’s actual take-home number by themselves; they’re one deduction line among several a seller has to net out before comparing a harvest-then-sell plan against selling the timberland as it stands.
Does enrollment status change what a small Oregon landowner owes?
Enrollment in the Small Tract Forestland Program is what triggers Oregon’s second layer of tax, and it isn’t automatic. A landowner with 10 to 4,999 acres of qualifying forestland can elect STF status to get a lower specially-assessed property valuation while the timber is growing, but that election is what creates the future severance tax bill at harvest — land taxed under Oregon’s regular forestland program or general property assessment doesn’t owe the STF severance tax, only the statewide FPHT that every Oregon harvest owes. A seller who inherited or bought Oregon timberland without knowing its assessment classification should check with the county assessor or the Oregon Department of Revenue before assuming which tax layers apply, since the STF severance tax bill can come as a surprise to an owner who didn’t realize the parcel had ever been enrolled.
