Short answer is no. People often confuse a business expense deduction with a tax credit. The gas deduction reduces your taxable income so the actual amount of the “savings” depends on your tax bracket. So if you are in the 15% bracket for instance, for every dollar you claim as a gas mileage deduction you are reducing your taxes by just 15 cents. This is a bit of an over simplication but the concept is valid.
