People are warned to be aware of fraudulant phone calls or emails claiming to be from the Canada Revenue Agency (CRA) – especially if they ask for personal information – which could result in identity and financial theft.
The CRA nevers ask for credit card, bank account, health card, driver’s licence and passport numbers or other personal information. 
Some of these scams ask for personal information directly while others refer to a website that looks like the CRA’s. Do not click on links included in these phishing emails. Email scams may also have embedded malicious software that can harm your computer and put your personal information at risk.
Some email scams say you are entitled to a refund of a specific amount. It says your tax assessment has been verified and you are getting a tax refund. These emails often look official, but some contain obvious grammar or spelling mistakes.
Some recent telephone scams use scare tactics by threatening or using forceful language get people to paying non-existent debt to the CRA. If you get such a call, hang up and report it to the Canadian Anti-Fraud Centre.
If you want to confirm the authenticity of a CRA telephone number, call the CRA by using the numbers on its Telephone numbers page. The number for business-related calls is 1-800-959-5525. The number for calls about individual concerns is 1-800-959-8281.
