Business Miles

• 1). Calculate the number of miles that you drove for business purposes, such as traveling from job to job if you work multiple jobs, or traveling from your workplace to another business during your working hours. You cannot include the miles that you drive from your house to your job or vice versa.
  
  
• 2). Determine the standard mileage rate for the tax year that you are taking the deduction. For 2009, the rate is 55 cents per mile for business miles.
  
  
• 3). Multiply the mileage rate times the number of business miles driven to calculate the value of your deduction. For example, if in 2009 you drove 400 miles for business purposes, you would be able to deduct $220 as a business expense.
  
  
• 4). Write the value of your business expense on line 21 of your schedule A to claim the deduction. You can also include any other unreimbursed business expenses on this line.
