While many practitioners are familiar with the need for U.S. Individual Taxpayer Identification Numbers ("ITIN"), we are not usually reminded about Canada’s version, the ITN.
The ITN is a nine-digit number issued by the CRA to non-resident individuals who require an identification number, but are not eligible to obtain a Social Insurance Number ("SIN"). An ITN is not available if you are otherwise able to obtain a SIN or if you already have an ITN or temporary tax number.
Some common examples of taxpayers requiring a Canadian ITN are:
The application for an ITN (form T1261) can be found at the CRA’s website http://www.cra-arc.gc.ca/E/pbg/tf/t1261/t1261e.pdf. There is no requirement that the documentation be notarized. The documents can be certified to be true copies by eligible individuals. Some examples of eligible individuals are accountants, bank managers, chiropractors, medical doctors, lawyers, clergy, police officers and CRA employees (at a CRA tax office, by appointment only).
When a T1261 is completed without a return, or when it is filed with a form NR5 or NR6, it should be filed at the International Tax Services office in Ottawa. Forms filed with section 116 clearance certificate requests or with regulation 105 or 107 waiver applications should be filed at the local tax services office.
