To sell firewood legally, you generally need a permit to sell firewood at two levels at minimum: a local business license from your city or county, and a sales tax permit from your state’s revenue department. Cut on federal land and you add a harvesting permit. Move wood across county or state lines and quarantine rules or heat-treatment certification come into play. The exact stack depends on where you harvest, where you sell, and how big the operation is.
The Baseline: Business License and Sales Tax Permit
Every firewood seller needs the same two documents any small business needs, and these are the ones people most often overlook while focusing on the wood itself.
A general business license gives you legal authority to operate inside a specific city or county. Fees vary widely by municipality, and most require annual renewal. Requirements differ even between neighboring towns, so call your city hall or county clerk rather than assuming your neighbor’s setup applies to you. Some jurisdictions scale the fee to gross revenue, which means a weekend seller moving a few cords a season may pay far less than a full-time operation.
A sales tax permit, also called a vendor’s license or seller’s permit, comes from your state’s department of revenue or taxation. It authorizes you to collect sales tax and obligates you to remit it on a schedule the state sets, whether monthly, quarterly, or annually depending on volume. A handful of states exempt firewood sold as residential heating fuel from sales tax, but you still need the permit on file to handle any taxable transactions.
Operating without the required licenses can bring fines and cease-operation orders.
Harvesting Permits on Public Land
Cutting firewood on federal land without a permit is a federal offense. The two agencies that manage most timber harvesting are the Bureau of Land Management and the U.S. Forest Service, and each runs its own process.
BLM permits can be bought through the agency’s online forest product permit system.1Bureau of Land Management. Online Forest Product Permits You pick a field office covering the area where you want to cut, select the product type and quantity, and pay through the government’s secure payment portal. Costs vary by office and season, and all online purchases are final with no refunds. Commercial harvesting on BLM land is handled separately, evaluated case by case through local field offices, and may require a contract rather than a standard permit.2Bureau of Land Management. Forest and Wood Product Permits
The Forest Service sells personal-use firewood cutting permits, with cost per cord varying by location.3USDA Forest Service. Firewood Permits The Forest Service does not appear to run a standardized commercial firewood permit program, so if you plan to harvest on National Forest land for resale, talk to the local ranger district before building supply plans around that wood.
Whichever agency you use, stay inside the boundaries, species limits, and volume caps on your permit.
Quarantine Rules When Wood Moves
The most consequential regulations for firewood sellers are the ones targeting invasive pests. Insects like the emerald ash borer and the Asian longhorned beetle travel inside firewood, and once they establish in a new area they can wipe out entire tree species across a region.
The USDA removed its federal domestic quarantine for the emerald ash borer on January 14, 2021, after the pest had spread too widely for a federal quarantine to remain practical.4Federal Register. Removal of Emerald Ash Borer Domestic Quarantine Regulations Enforcement moved to individual states, many of which tightened their own rules. State firewood movement limits are typically framed as a set distance from the harvest site, with common thresholds at 10, 25, or 50 miles. Some states draw quarantine boundaries by county or regulated area instead.5National Invasive Species Information Center. Firewood
Violating a quarantine can bring civil fines and, in serious cases, criminal prosecution. The practical rule is to source and sell locally when you can. When you cannot, contact your state’s department of agriculture about a compliance agreement, which formalizes your commitment to specific handling and treatment protocols for wood from quarantined zones.
Heat-Treatment Certification for Interstate Sales
Firewood that crosses state lines or enters the country generally has to be heat-treated and certified. USDA sets specific temperature and duration requirements: hardwood must reach 140°F at the core for 60 minutes, and softwood must reach 133°F at the core for 30 minutes. Commercial shipments must carry a treatment certificate issued by the processing facility, and noncommercial shipments need either a certificate or an attached commercial treatment label.6USDA APHIS. Don’t Be Delayed at the Border – Make Sure Your Firewood Is Heat-Treated
How You Have to Measure and Advertise the Wood
Most states follow the measurement standards in NIST Handbook 130, the national reference that state weights-and-measures agencies adopt. Under those standards, firewood must be advertised, offered for sale, and sold by the cord or a fraction of a cord. A cord is 128 cubic feet, ranked and well stowed. Picture a stack four feet wide, four feet tall, and eight feet long, with the pieces touching and parallel.7NIST. Handbook 130 – Uniform Regulation for the Method of Sale of Commodities
Packaged natural wood sold in quantities under one-eighth of a cord (16 cubic feet) follows different rules and must display net quantity in liters or cubic feet rather than cords.7NIST. Handbook 130 – Uniform Regulation for the Method of Sale of Commodities Wood pellets and chips must be sold by weight.
Terms like “face cord,” “rick,” “rack,” and “truckload” have no legal definition. Using them in advertising or on a receipt violates measurement rules in states that follow Handbook 130, and weights-and-measures inspectors do check. Small sellers get tripped up here more than anywhere else, using a familiar local term without realizing it creates an enforcement problem.
Every sale should come with a receipt or delivery ticket that includes:
- Your name and business address
- The customer’s name
- The date of sale or delivery
- Quantity in cords, fractions of a cord, or cubic feet
- The total price
Some states go further and require listing the wood species, its quality, or the county and state where it was harvested. Ask your state’s weights-and-measures office about local additions.
Federal Taxes the Sales Permit Triggers
The sales tax permit gets attention. Federal taxes get forgotten, and that mistake is the more expensive one. As a sole proprietor, the default if you have not formed an LLC or corporation, you report your firewood income and expenses on Schedule C, filed with your personal Form 1040.8Internal Revenue Service. Sole Proprietorships
On top of income tax, you owe self-employment tax on your net earnings. This covers the Social Security and Medicare contributions an employer would ordinarily split with you. The combined rate is 15.3% of net earnings, and Schedule SE is required once your net self-employment income reaches $400 or more for the year.9Internal Revenue Service. 2025 Instructions for Schedule SE (Form 1040)
If you expect to owe $1,000 or more in combined income and self-employment tax for the year, the IRS requires quarterly estimated payments due in April, June, September, and January. Miss them and an underpayment penalty accrues interest until you catch up.10Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty This catches seasonal sellers off guard: most revenue arrives in fall and winter, but the IRS expects payments spread across the year.
You do not need an Employer Identification Number as a sole proprietor with no employees. Your Social Security number covers tax purposes.11Internal Revenue Service. Get an Employer Identification Number That said, an EIN is free, takes about five minutes online, and keeps your Social Security number off invoices and business documents.
Insurance and Delivery Vehicle Rules
No federal law forces a firewood business to carry liability insurance, but going without it is a gamble most sellers should not take. If a customer’s chimney fire gets traced to improperly seasoned wood, or a delivery driver tears up a driveway, you are personally on the hook.
The SBA recommends that businesses selling physical products carry general liability and product liability coverage. A business owner’s policy bundles these with commercial property coverage and is often the most cost-effective option for a small operation. Running the business from home, a rider on your homeowner’s insurance may cover limited business equipment and third-party injuries.12U.S. Small Business Administration. Get Business Insurance
Delivery vehicles are their own category. Personal auto insurance almost always excludes commercial use, so any vehicle used for firewood delivery needs a commercial auto policy. Haul loads in interstate commerce with a vehicle rated at 10,001 pounds GVWR or more and you need a USDOT number from the Federal Motor Carrier Safety Administration.13Federal Motor Carrier Safety Administration. Do I Need a USDOT Number For-hire property carriers also face mandatory liability minimums: $300,000 for vehicles under 10,001 pounds GVWR, and $750,000 for heavier vehicles.14Federal Motor Carrier Safety Administration. Insurance Filing Requirements
If your loaded truck-and-trailer combination is over 26,000 pounds GVWR and the trailer alone is over 10,000 pounds, the driver needs a Class A commercial driver’s license. A single vehicle over 26,000 pounds requires at least a Class B.15eCFR. 49 CFR 383.91 – Commercial Motor Vehicle Groups Most firewood operations stay well under these thresholds with a standard pickup and trailer. If you are running a heavy dump truck or large flatbed, check the GVWR on the door sticker before assuming you are clear.
What To Have Ready When You Apply
Gathering these items before you start any application will save multiple trips:
- Your legal business name and any DBA you use publicly
- Government-issued photo ID and your Social Security number or EIN
- A short business description covering what you sell, how you sell it, and expected monthly revenue
- The physical address where the business operates, including any storage locations
- The county and state where you cut or buy your wood, which many state agricultural and weights-and-measures applications require
- Bank account details, often required for sales tax registration so the state can process refunds or debits
Most states now offer online applications through the department of revenue or secretary of state website, and BLM harvesting permits go through the agency’s online portal.1Bureau of Land Management. Online Forest Product Permits Processing times vary. A sales tax permit might arrive within a week; a general business license from a city or county office can take two to three weeks. Mail-in applications are still available at most agencies, with longer turnaround.
