tracking the mileage to and from local interviews, or to and from a trip to the airport for an out-of-town interview, along with the cost of airport parking. Buy a calling card to make phone calls to recruiters and prospective employers, then save the receipt. Out-of-town meals, gas for a rental car, the rental car itself (if the prospective employer doesn't pick up the tab initially or reimburse you later).
BUT...
You can only deduct what's higher than 2% of your adjusted gross income. Every little bit helps tho.
How's the job search going, Orion?
