Is writing off gas on taxes a valid tax write-off?

TL;DR

Gas expenses can be deductible if they are directly related to business use.

Detailed Answer

Gas expenses are deductible when they are incurred for business purposes. This includes driving for business meetings, client visits, or other business-related travel. Personal use of a vehicle is not deductible. Taxpayers can choose between deducting actual expenses, including gas, or using the standard mileage rate for business travel.

Where to Put It on the Tax Form

Schedule C (Form 1040), Line 9 for car and truck expenses

Real World Example

A freelance graphic designer drives 100 miles to meet a client. They can deduct the cost of gas for this trip if they choose the actual expense method.

Calculation Required

A calculation is required for this deduction.

To calculate the deduction using actual expenses, track all vehicle-related costs (gas, maintenance, insurance, etc.) and multiply by the percentage of business use. Alternatively, multiply total business miles by the IRS standard mileage rate.

Audit Risk & Documentation Tips

Maintain a detailed mileage log and keep receipts for all vehicle-related expenses. Be prepared to prove the business purpose of each trip to minimize audit risk.
