The new form for qualifying non-resident employer certification requires only basic details

On January 12, 2016, CRA released the form for (Treaty-exempt) non-resident employers to apply for certification as "qualifying non-resident employers" so as to be exempt from source deduction requirements on remuneration paid to "qualifying non-resident employees" (broadly, Treaty-exempt non-resident employees who work in Canada for less than 45 days in the calendar year of payment or are present in Canada less than 90 days in any 12-month period that includes the payment time). The RC473 form must be filed by the end of February 1, 2016 in order for certification to be treated as retroactive to January 1, 2016.

The applicant non-resident employer is not required to provide employee details or any travel data, so that the form mainly serves as a notification to CRA that the non-resident employer will have non-resident employees working in Canada during the certified period.
