How do I deduct how to write off gas as a business expense on my taxes?
Gas expenses are deductible when they are incurred for business purposes, such as driving to meet clients or traveling between different work sites. Personal use of the vehicle does not qualify for a deduction. To claim this deduction, taxpayers can use either the actual expense method, which includes gas, or the standard mileage rate, which simplifies the deduction process by using a set rate per mile driven for business purposes.
