Will I be able to deduct interview travel costs for a new job? and add it to the total travel moving expenses?

You can deduct interview travel expenses but cannot add it to the moving expenses. They are separate expenses requiring two separate data entries, as there is a separate "tax treatment" for each.

To enter interview travel costs:

a.      Wages &Income tab (Personal Income in Home &Business)

b.      Deductions and Credits

c.      Employment Expenses, select “Job-Related Expenses”

To enter moving expenses:

a.      Wages &Income tab (Personal Income in Home &Business)

b.      Deductions and Credits

c.      Other Deductions and Credits, select “Moving Expenses”

You can deduct certain expenses you have paid in looking for a new job in your present occupation, even if you do not get a new job. You cannot deduct the job search expenses if you are looking for a job in a new occupation, there was a substantial break between the ending of your last job and you are looking for a new one, or you are looking for a job for the first time.

The expense include:

a. Employment and outplacement agency fees.

b. Amounts you spend for preparation and mailing copies of a resume.

c. Travel expenses if the trip is primarily to look for a new job.

For more information, please refer to the IRS publication 529.
