I relocated last year and meet the moving cost deduction criteria. My company paid for the most part of my relocation, and in my W2 form Box 12 there's a code P and an amount. I checked my paystub from last year, that amount was correspond to "Non Taxable Relo", but I can't recall the itemized detail for this reimbursement.
Addition to these I paid for some relocation items myself that the company didn't cover, for example, moving my household pets.
When I tried to enter these additional cost in Turbotax, it subtract the amount in Box 12 from the moving cost I paid myself. Do I need to enter Box 12 P amount in addition to my self paid moving items here? But it shows "non taxable relo" I assume it shouldn't appear anywhere on my tax forms.
You enter your total moving costs and expenses in the Moving Expense section of TurboTax.
The program will then offset those expenses by any employer reimbursement you received shown on your W2 (if you have additional reimbursement not shown, then you would also enter that) and you will receive a deduction for any excess expenses for which you did not receive a reimbursement.
You need to enter your total moving expense this way because if you didn't use all the money for your relocation expenses, then the excess would actually become taxable income and added back to your wages.
