Can I Write This Off?

Can you write off can i write off my gas for work?

TL;DR

You can generally deduct gas expenses for work if you are self-employed and the vehicle is used for business purposes. However, employees cannot deduct these expenses unless they are unreimbursed and meet specific criteria.

Detailed Answer

Gas expenses are deductible for self-employed individuals, freelancers, and business owners when the vehicle is used for business purposes. This includes driving to meet clients, travel between job sites, and other business-related travel. Personal commuting expenses, such as driving from home to your regular place of business, are not deductible. If you use your vehicle for both personal and business purposes, you must determine the percentage of business use and apply that percentage to your gas expenses. For employees, gas expenses are generally not deductible unless they are unreimbursed employee expenses that meet the criteria for deductibility under prior tax law, which was largely suspended for tax years 2018 through 2025 due to the Tax Cuts and Jobs Act.

Where to Put It on the Tax Form

Schedule C, Line 9 for self-employed individuals. If using the standard mileage rate, report on Schedule C, Line 9 and attach Form 4562 if required.

Real World Example

A freelance graphic designer drives 5,000 miles in a year for client meetings and project site visits. If the total gas expense for the year is $1,200 and 60% of the miles driven are for business, they can deduct $720 (60% of $1,200) as a business expense on their Schedule C.

Calculation Required

A calculation is required for this deduction.

To calculate the deductible portion of gas expenses, determine the total miles driven for business purposes and divide by the total miles driven for the year to find the business use percentage. Multiply this percentage by the total gas expenses to find the deductible amount.

Audit Risk & Documentation Tips

Moderate. Keep detailed records of all business trips, including dates, destinations, purposes, and miles driven. Maintain receipts for all gas purchases and a mileage log to substantiate the business use percentage. Consider using a mileage tracking app for accuracy.
