Is is gas a write off a valid tax write-off?

Gas expenses are deductible when they are incurred for business purposes. This means if you use your vehicle for work-related travel, such as visiting clients or traveling between different work sites, you can deduct the cost of gas. However, personal use of your vehicle, including commuting from home to your regular place of work, is not deductible. You can choose to deduct actual expenses, including gas, or use the standard mileage rate set by the IRS.
