Can I deduct writing off gas on taxes?

Gas expenses are deductible when they are incurred for business purposes, such as driving to meet clients, attending business meetings, or traveling between different work sites. Personal use of a vehicle, such as commuting to and from a regular place of work, is not deductible. To claim this deduction, you can use either the actual expense method, where you deduct the actual cost of gas and other vehicle expenses, or the standard mileage rate, which includes gas costs.
