If you maintain your office in your home and your home is your principal place of business, you may be entitled to a special tax break on your commuting costs. Taxpayers can deduct daily costs of travel between their home and another work location in the same business, regardless of whether the other location is regular or temporary. Simply remember to keep adequate records, via a diary or log, of your expenses and mileage during the year and you will be eligible to deduct one or the other at the end of the year.
