Can I Write This Off?Is can i write off gas as a business expense a valid tax write-off?
TL;DR
Gas can be written off as a business expense if it is used for business purposes, but it must be properly documented and separated from personal use.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 9 for car and truck expenses. If using Form 2106, it would be included in Part II.
Real World Example
A freelance graphic designer who drives 5,000 miles in a year for client meetings and project site visits can deduct either the actual gas expenses incurred or use the standard mileage rate, which would result in a $3,275 deduction (5,000 miles x 65.5 cents).
Calculation Required
A calculation is required for this deduction.
To calculate the deduction using the standard mileage rate, multiply the business miles driven by the IRS mileage rate (e.g., 5,000 miles x 65.5 cents). For actual expenses, calculate the percentage of business use and apply it to total vehicle expenses, including gas.
Audit Risk & Documentation Tips
Moderate audit risk. Maintain a detailed log of business miles driven, including dates, destinations, and purpose of trips. Keep all gas receipts and any other vehicle-related expense records. Consider using a mileage tracking app for accuracy.
