It depends on whether or not you are going to be reimbursed for the move. If you are going to be, then you will wait and deduct the storage expenses along with your other expenses in 2017. If you are not going to be, then you will claim the storage expenses this year and the other expenses in 2017.
Please see When to Deduct Expenses on page 12, IRS Publication 521, for more information.
