Is can i write gas off on my taxes tax deductible?
TL;DR
Gas expenses can be tax deductible if they are directly related to business use of a vehicle. Personal use of gas is not deductible.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 9 for car and truck expenses if using actual expenses; or Line 44 for other expenses if using the standard mileage rate.
Real World Example
A freelance photographer drives 200 miles in a year to various client locations. Choosing the standard mileage rate, they deduct $131 (200 miles x $0.655) instead of tracking actual gas expenses.
Calculation Required
A calculation is required for this deduction.
To calculate the deduction using the standard mileage rate, multiply the total business miles driven by the IRS mileage rate (e.g., 200 miles x $0.655). If using actual expenses, track and sum all vehicle-related expenses, then multiply by the percentage of business use.
Audit Risk & Documentation Tips
Moderate audit risk. Maintain a detailed mileage log showing dates, miles driven, and business purpose. Keep receipts for all vehicle expenses if using the actual expense method. Consider using apps or tools to track mileage automatically.
