The scenario is as follows:

1) New company ? LLC. One partner until 4/1/17. One W-2 employee who will transition to partner Q2 2017. He has to be a W-2 employee until then for purposes of a pending personal mortgage. Their agreement is written as such.
2) The W2 employee is going to deposit $50k of his personal money into the company as a loan to cover his payroll until he is made a partner on 4/1/17.

If he makes the loan as noted above isn?t he technically being taxed on the $50k twice. He was taxed on the $50k made this year personally which he is using to loan to the company and now he will be taxed again on the $50k through W-2 wages.

Is there another way to do this to avoid this and still have the W2 needed for the loan?
