Nanny Payroll Taxes and Employer Identification Number (EIN)
I own my own small business as a sole proprietor (no employees but myself). My wife and I will be hiring a nanny for the summer for our household (not associated with the business).
I plan to work through a payroll company to handle payroll taxes. According to Schedule H (https://www.irs.gov/instructions/i1040sh#en_US_2022_publink21451xd0e538), I will need an EIN to file. Should I use the EIN set up for my small business or have my wife set up a separate EIN to keep the household employee separate? To be clear, the nanny will *not* be an employee of the business.
