Is can i write off gas on my taxes a valid tax write-off?
TL;DR
Gas expenses can be deductible if they are incurred for business purposes, but personal use of gas is not deductible. It's important to distinguish between business and personal use to ensure compliance with IRS rules.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 9 for actual vehicle expenses or Line 44 for the standard mileage rate. If using Form 2106, report on Line 2 for employee business expenses.
Real World Example
A freelance graphic designer drives to meet clients and attend industry conferences. They track their business mileage and choose to deduct actual expenses, including $500 spent on gas for these trips, on Schedule C, Line 9.
Calculation Required
A calculation is required for this deduction.
To calculate the deductible amount, keep a log of total miles driven for business versus personal use. If using actual expenses, calculate the percentage of business use by dividing business miles by total miles driven, then apply this percentage to your total gas expenses.
Audit Risk & Documentation Tips
Moderate audit risk. Maintain a detailed mileage log, including dates, destinations, and business purpose of each trip. Keep all gas receipts and any other relevant documentation. Consider using a mileage tracking app for accuracy and convenience.
