Can you write off can you write off gas on taxes?

TL;DR

Gas expenses can be deductible if they are directly related to business use of a vehicle. It's important to distinguish between personal and business use to ensure proper deduction.

Detailed Answer

Gas expenses are deductible when they are incurred for business purposes, such as driving to meet clients or traveling between job sites. Personal commuting costs, like driving from home to a regular workplace, are not deductible. Taxpayers can choose between deducting actual expenses, including gas, or using the standard mileage rate, which encompasses gas and other vehicle-related costs. For the actual expense method, you must calculate the percentage of business use and apply it to your total vehicle expenses. For example, if 60% of your vehicle use is for business, you can deduct 60% of your gas expenses. Keep in mind that meticulous records must be maintained to substantiate business use.

Where to Put It on the Tax Form

Schedule C, Line 9 for car and truck expenses. If using Form 2106, report on Line 1.

Real World Example

A freelance photographer uses their personal vehicle to travel to various client locations for photo shoots. They track their mileage and determine that 70% of their vehicle use is for business. They spend $2,000 on gas annually and can deduct $1,400 (70% of $2,000) as a business expense.

Calculation Required

A calculation is required for this deduction.

To calculate the deductible amount, determine the percentage of business use by dividing business miles by total miles driven. Multiply this percentage by the total gas expenses to find the deductible portion.

Audit Risk & Documentation Tips

Moderate audit risk. Maintain a detailed mileage log, including dates, destinations, and business purposes of trips. Keep gas receipts and any other relevant vehicle expense documentation. Consider using apps or tools to track mileage and expenses accurately.
