To claim the car expenses deduction, you must file Form 1040, Schedule C. On this form, you will need to list the total number of miles you drove your car for business and the total number of miles you drove your car for personal use. You will also need to list the actual expenses you incurred in operating your car. If you are using the standard mileage rate, you will need to multiply the number of business miles you drove by the standard mileage rate.
The standard mileage rate for 2010 is 0.50 cents per mile. This means that if you drove your car 10,000 miles for business in 2010, you can deduct $5,000 on your taxes.
You can also deduct other car-related expenses, such as parking fees and tolls. You can also deduct the cost of any improvements you made to your car that are necessary for business, such as a roof rack or a GPS system.
If you have any questions about claiming the car expenses deduction, you should consult with a tax advisor.
