How do I deduct can you write off gas as a business expense on my taxes?

Gas expenses can be deducted when the vehicle is used for business purposes. This includes travel between job sites, client meetings, or other business-related travel. However, commuting from home to a regular place of business is not deductible. You can choose between deducting actual expenses, which include gas, or using the standard mileage rate, which covers all vehicle-related costs.
