It's important to know the number of miles you commute to work so you can deduct your driving costs at tax time. As of January 1, 2011, the Internal Revenue Service allows individuals, small-business employees and other taxpayers to deduct the federal standard mileage reimbursement rate for each mile driven to and from work. If you are contemplating whether to accept a new job offer, you might want to compare the total number of miles you commute to work for your current employer versus what it would need to be for the potential employer.

## Step 1

Determine the number of round-trip miles you travel per commute day. Find the number of miles between your house and your job using an online distance calculator. Calculate the round-trip miles by doubling the one-way miles.

## Step 2

Determine the number of commute days you travel per month. If your schedule changes, enter the average number of commute days you travel per month.

## Step 3

Multiply the number of round-trip miles you travel per commute day by the number of commute days you travel per month.

## Step 4

Multiply the result in Step 3 by the total number of months -- 12 -- in a year to determine the total number of miles you commute to work each year.
