Can I deduct the airfare cost for out-of-state job interviews?

[bwa]

That would be a deduction for job search costs, an employee business expense. Employee business expenses are a limited deduction. You can claim them only if:

• You can itemize deductions, and
• they exceed 2% of your adjusted gross income.

If your miscellaneous itemized deductions clearly don't exceed 2% of your adjusted gross income there is no need to go through the time consuming effort to enter them. If they are over 2%, under the deductions and credits tab at the bottom of the list under other deductions and credits. Look for other deductions.

Turbotax explains the 2% rule at this site.

For employee business expenses look under Federal Taxes, then Deductions and Credits, then Explore on My Own, then Employment Expenses (near the bottom.)
