Do I need to report that I am working two jobs on my W-2 if I am on leave from one, to work the other?

Hi everyone, I am currently interning for the summer at a new company, and went on leave at my old job for a few months because of the internship. I have not worked both at the same time, but am still technically an employee of the first job during this time. On the internship's W-2 for both state and federal (MN for state) do I have to report I am working two jobs, even though I am only working at the one?

I think you mean your W-4--the document you fill out for the employer so the employer will know how much tax to withhold from your paychecks.   You are not the one who fills out a W-2---in January your employer(s) issue W-2's to show how much you earned and how much was withheld for taxes.

Each employer will withhold as if your job with them is your only job.   If you want more -- or less -- tax withheld from your paychecks then you may want to adjust the withholding you want on the W-4 you give to the employers.

Exactly like the Champ explained, in other words, you don't have to do anything, you will get two W2s at the end of the year anyways, which will obviously be reported in your taxes since technically, you are still on payroll of both jobs, whether on leave or not. As far as by reporting, if you meant informing the other employer (if I am not mistaken), well by law you don't have to, just fill out the W4, which you must have done by now, I am sure.
