How do I deduct can i write off my gas for work on my taxes?
TL;DR
Gas expenses for work can generally be deductible if they are directly related to business use, but personal commuting is not deductible.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 9 for car and truck expenses, or Form 2106 for employee business expenses if not reimbursed.
Real World Example
A freelance graphic designer drives 100 miles to meet a client and deliver a project. They can deduct the gas expense for this trip by either calculating the actual cost of gas used or applying the IRS standard mileage rate to the 100 miles driven.
Calculation Required
A calculation is required for this deduction.
To calculate the deduction using the standard mileage rate, multiply the total business miles driven by the IRS standard mileage rate for the year. For actual expenses, calculate the percentage of business use and apply it to total vehicle expenses, including gas.
Audit Risk & Documentation Tips
Moderate audit risk. Keep a detailed mileage log or use a mileage tracking app to record dates, miles driven, and business purpose of each trip. Retain gas receipts and any related documentation to substantiate your deduction.
