Is can you deduct gas and mileage a valid tax write-off?

To deduct gas and mileage, the vehicle must be used for business purposes. There are two methods to claim this deduction: the standard mileage rate and the actual expenses method. The standard mileage rate is simpler and involves multiplying the business miles driven by the IRS mileage rate (e.g., 65.5 cents per mile for 2023). The actual expenses method requires calculating the actual costs of operating the vehicle, including gas, and then multiplying by the percentage of business use. Personal commuting is not deductible. For example, if you drive 10,000 miles in a year and 6,000 of those are for business, you can deduct 60% of your actual expenses or use the standard mileage rate for those 6,000 miles.
