What expense category is Sunoco?
Fuel distributor and gas station brand supplying gasoline, diesel, and related fuel products to vehicles and commercial fleets.

How businesses classify Sunoco
Tax details
- Fuel purchases for company-owned vehicles used exclusively for business are 100% deductible — maintain a mileage log or fleet record to support full deductibility
- If employees use personal vehicles for business and are reimbursed at the IRS standard mileage rate, fuel costs are already included in that rate and cannot be separately deducted
- For mixed-use vehicles (personal and business), only the business-use percentage of fuel costs is deductible — track business vs. personal mileage with a mileage log app
- Fleet accounts with Sunoco or fuel cards should be reconciled monthly to ensure only business-related fuel purchases are expensed
- Diesel fuel for job site equipment (generators, heavy machinery) is generally 100% deductible as a business operating expense — keep receipts noting the equipment and project
