Is is gas a business expense tax deductible?

TL;DR

Gas can be a business expense tax deductible if it is used for business purposes.

Detailed Answer

Gas expenses are deductible when they are directly related to business activities. This includes driving to meet clients, traveling between job sites, or any other business-related travel. Personal use of gas is not deductible. To claim this deduction, taxpayers can use the actual expense method, which involves tracking all vehicle-related expenses, or the standard mileage rate, which simplifies the process by allowing a deduction based on the number of business miles driven.

Where to Put It on the Tax Form

Schedule C (Form 1040), Part II, Line 9 for sole proprietors or as part of unreimbursed employee expenses on Schedule A if applicable.

Real World Example

A freelance photographer drives 100 miles to a client's location for a photo shoot. The gas used for this trip is deductible as a business expense.

Calculation Required

A calculation is required for this deduction.

If using the actual expense method, calculate the percentage of business use of the vehicle and apply it to the total gas expenses. Alternatively, multiply the business miles driven by the IRS standard mileage rate.

Audit Risk & Documentation Tips

Maintain a detailed mileage log showing dates, destinations, business purposes, and miles driven. Keep receipts for gas purchases if using the actual expense method. Accurate records reduce audit risk and substantiate the deduction.
