<prompt> Human: So I am a newlywed and my wife works as a nanny.I just found out that she hasnt paid taxes on her income while working for a family for the past 9 years. They give her a paycheck but nothing is taken out and she isnt given a W2 or anything like that.I want to file my own taxes but I now have to file as married. Even if I file separately, I have to provide her name, SS, etc.Will this alert the IRS to her situation?What should we do? I cant imagine the amount of money they would want.Please help. Any and all advice appreciated.  <response>: So I am a newlywedWere you married on or before 12312017? and my wife works as a nanny.Assuming she performed the service in the familys home and made more than 2,100 per year, she should probably have been treated as a Household Employee the entire time.
