Per diem is the amount allowed per day for over the road or regional truck drivers that are away from home over night. It is a meal allowance. Add all the days you was away from home overnight and multiply those days by allowed amount per day. You can get this info from the IRS or tax preparer
Keep track of the days you are away from home, Jan to Dec. You can deduct say $35.00 a day for meals for every day you are on the road, on schedule A of your 1040 Fed tax. If your an owner/operator, well thats a whole different ball game. Make sure you let your tax preparer know that you are an over the road truck driver. Tell her how many days during the year you were away from home. Instead of saving every meal receipt, uncle sam will give you a per diem amount per day for meals as a deduction. It comes under job expenses.
