The letter claims there is "insufficient information" for the individual's tax return and that in order to receive any "claims," they will have to update their records. The letter attaches a form specifically requesting the individual's personal information in writing, via fax or email, including information on bank accounts and passports.

This letter is not from the CRA and Canadians should not provide their personal information to the sender. The law enforcement authorities have been notified.

Tax consultants are also alerting their clients about the fraudulent mail. For a PDF version of the scam letter visit www.cra.gc.ca/alert
