Heavy Truck Excise Tax Exemptions Explained
Common exemptions
- Export — vehicles sold for export from the United States
- State & local government — sales for a government unit's exclusive use
- Further manufacture — sales to a buyer who will use the article to make another taxable article
- Below threshold — trucks ≤ 33,000 lbs or trailers ≤ 26,000 lbs GVW
- Certain nonprofit / qualified uses as provided by statute
The 6-month / 75% repair exclusion
Rebuilding a used vehicle generally isn't taxable "manufacture" unless the cost of the work exceeds 75% of the retail price of a comparable new vehicle. This keeps ordinary repairs from triggering the 12% tax. For what is taxable, see the 12% heavy truck tax overview.
FAQ
What sales are exempt from the heavy truck excise tax?▼
Common exemptions include sales for export, sales to state and local governments for their exclusive use, sales for use by certain nonprofits, sales for further manufacture, and sales of vehicles below the GVW thresholds. Proper exemption certificates are usually required.
Is the 6-month / 75% repair exclusion relevant?▼
Yes. Restoring a used vehicle is generally not a taxable "manufacture" unless the cost of the work exceeds 75% of the retail price of a comparable new vehicle. This affects whether a rebuilt truck triggers the 12% tax.
How do I document an exempt heavy truck sale?▼
Keep the buyer's exemption certificate (for example, a government or export certificate) and records supporting the exempt use. Without proper documentation, the IRS may treat the sale as taxable and assess the 12% tax against the seller.
