Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
Yes, the Q S Sub would use its own EIN to process payroll, but everything will be consolidated into the parent come tax time.
Is there anything additional I can assist you with today?
If not, would you please rate my response as "excellent" so that I may receive credit for assisting you today. Thanks again
