EHT is a payroll tax, on remuneration paid by employers who have a permanent establishment (PE) in Ontario, and who:
Eligible employers with annual total Ontario remuneration in excess of their exemption amount, eligible employers who are associated employers, and employers who are not eligible for the tax exemption are required to register.
Once registered, the employer receives an EHT account number. One EHT account number is usually assigned to each employer; however, an employer can have more than one EHT account number set up for different payroll centres or payroll types, if desired.
