Is is gas deductible for self-employed a valid tax write-off?

TL;DR

Gas expenses can be deductible for self-employed individuals if they are directly related to business use.

Detailed Answer

Self-employed individuals can deduct gas expenses if they are incurred for business purposes, such as driving to meet clients, making deliveries, or traveling between business locations. Personal use of a vehicle, commuting from home to a regular place of business, and other non-business-related travel are not deductible. The deduction can be taken using the actual expense method, where you track all vehicle-related expenses, or the standard mileage rate method, which includes gas as part of the 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 graphic designer uses their personal car to travel to client meetings and industry events. They track the miles driven for these business purposes and deduct the gas expenses using the standard mileage rate.

Calculation Required

A calculation is required for this deduction.

If using the actual expense method, calculate the percentage of total vehicle expenses attributable to business use. If using the standard mileage rate, multiply the business miles driven by the IRS standard mileage rate for the year.

Audit Risk & Documentation Tips

To minimize audit risk, keep a detailed mileage log showing dates, mileage, and purpose of each trip. Retain receipts for gas and other vehicle expenses if using the actual expense method. Ensure personal and commuting miles are not included in the deduction.
