Can I Write This Off?

Is can you write off gas on taxes tax deductible?

TL;DR

Gas expenses can be tax deductible if they are directly related to business use of a vehicle. However, personal use of a vehicle is not deductible, and proper documentation is essential.

Detailed Answer

Gas expenses are deductible when they are incurred for business purposes. This means if you use your vehicle to travel to client meetings, deliver goods, or perform other business-related activities, you can deduct the cost of gas. However, commuting from home to your regular place of business is considered personal use and is not deductible. You must choose between deducting actual expenses (including gas) or using the standard mileage rate. If you opt for actual expenses, you must keep detailed records of all vehicle-related costs and calculate the business-use percentage. For example, if 60% of your vehicle use is for business, you can deduct 60% of your gas expenses.

Where to Put It on the Tax Form

Schedule C, Line 9 for car and truck expenses. If using Form 2106 for employee business expenses, report on Line 2.

Real World Example

A freelance photographer drives 5,000 miles in a year for business purposes and spends $1,000 on gas. If 75% of the total miles driven are for business, they can deduct $750 of the gas expenses on their Schedule C.

Calculation Required

A calculation is required for this deduction.

To calculate the deductible amount, determine the percentage of business use of the vehicle. Multiply the total gas expenses by this percentage. For example, if 75% of your driving is for business, multiply the total gas cost by 0.75.

Audit Risk & Documentation Tips

Moderate audit risk. Keep detailed records, including a mileage log showing dates, destinations, and purpose of trips. Save all gas receipts and maintain a calendar of business activities to substantiate the business use of the vehicle.
