should i put down gas receipts

Assuming that your gas receipts are with respect to your business and you are self-employed you will enter your gas receipts on your Schedule C.

You will enter expenses relating to your vehicle in one of two ways:

• The standard mileage rate, or
• Actual expenses

Which one you use depends on which one you think will give you the highest deduction, the standard mileage rate or actual costs.

• The more economical your vehicle is to operate, the more likely it is that the standard mileage rate will give you the bigger deduction.
• The higher your vehicles operating costs (Such as gas, repairs, tires, etc.)  the more beneficial the actual cost method will be.
