If you are an employee who will receive a W-2, you can claim your unreimbursed employee expenses on Form 2106.
Expenses that you pay out of pocket are claimed on Form 2106. Then, the total amount from that form is included as part of Schedule A, Itemized Deductions. This means that in order to receive a tax benefit for claiming unreimbursed employee expenses, you must be using itemized deductions.
To go to the section of your return to enter your expenses, use these steps:
On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
This opens a box where you can type in “2106” (be sure to enter exactly as shown here) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
The search results will give you an option to “Jump to 2106”
Click on the blue “Jump to 2106” link
