is gas tax deductible for business?

TL;DR

Gas is deductible for business purposes if it is used in the operation of a vehicle for business activities.

Detailed Answer

Gas expenses are deductible when they are incurred for business purposes, such as driving to meet clients, delivering goods, or traveling between business locations. Personal use of a vehicle does not qualify for a deduction. The deduction can be claimed using the actual expense method, where you track and deduct the actual cost of gas, or the standard mileage rate, which includes gas as part of the per-mile rate.

Where to Put It on the Tax Form

Schedule C (Form 1040), Part II, Line 9 (Car and Truck Expenses)

Real World Example

A freelance photographer drives to various locations for photo shoots. They track their gas expenses and mileage for these trips and claim the deduction on their tax return.

Calculation Required

A calculation is required for this deduction.

If using the actual expense method, calculate the total cost of gas used for business purposes. If using the standard mileage rate, multiply the business miles driven by the IRS standard mileage rate.

Audit Risk & Documentation Tips

Maintain a detailed mileage log and keep receipts for gas purchases. Document the business purpose of each trip to substantiate the deduction in case of an audit.
