Cyber Attacks & Ransomware

With cyber attacks and security issues on the rise and the CRA becoming more technology friendly, it is vital to remember the below items as you go through any correspondence received from the CRA:

CRA will not do the following:
– send an email with a link and ask you to divulge personal or financial information.
– ask for personal information of any kind by email or text message.
– request payments by prepaid credit cards.
– Share your tax information with another person, unless formal authorization is provided by the taxpayer.
– leave personal information on an answering machine.
– Leave you threatening messages asking for a call back.
