How do I deduct can you write off gas on taxes on my taxes?
TL;DR
Gas expenses can be deductible if they are directly related to business activities, but personal use is not deductible. It's important to distinguish between business and personal use to ensure compliance with IRS rules.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 9 for car and truck expenses. If using Form 2106 for employee business expenses, it would be on Line 1.
Real World Example
A freelance graphic designer drives 200 miles in a year to meet with clients and attend industry events. Using the standard mileage rate, they can deduct $131 (200 miles x $0.655) on their Schedule C. They keep a logbook detailing each trip's date, purpose, and 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 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 with dates, destinations, and business purposes. Save all gas receipts if using the actual expense method. Consider using apps to track mileage automatically to ensure accuracy and compliance.
