How do I deduct can i write off gas and mileage on my taxes?

You can deduct vehicle expenses using either the standard mileage rate or actual expenses method. The standard mileage rate, set annually by the IRS, covers all vehicle-related costs, including gas, maintenance, and depreciation. Alternatively, the actual expenses method allows you to deduct the actual costs of operating the vehicle, such as gas, oil, repairs, insurance, and depreciation, but only the portion that applies to business use. To use either method, you must keep detailed records of your business miles driven. Note that commuting miles (driving from home to your regular place of work) are not deductible. For example, if you drive to meet clients or attend business meetings, those miles are deductible.
