The security mechanisms that we have put into place for our website are effective only if you follow certain basic rules.

Protect your personal information and identification data

Make sure that the information used to validate your identity, especially your user code and your password, remain confidential.

We recommend that you modify your password every three to six months and avoid using personal information as your password.

If you decide to print or write down your user code and password, we recommend that you do so on separate sheets that you keep them in separate secure locations.

Should the confidentiality of the information be violated, please inform us immediately to avoid its fraudulent use.

Beware of fraudulent emails

The technology and equipment we use safeguards and protects the confidentiality of transactions and communications via our online services.

If you receive an email, text, phone call or letter that claims to be from Revenu Québec and seems suspicious to you, keep in mind the following:

  • Revenu Québec never requests the following personal information by email or text:
    • the amount from line 199 of your income tax return
    • your date of birth
    • a notice of assessment number
    • a notice of determination number
    • your social insurance number
    • your health insurance number
    • your driver's licence number
    • your passport number
    • a password
  • Revenu Québec never mentions confidential information in a phone message.
  • Revenu Québec never shares your personal information with anyone without making sure that the person receiving it is authorized to do so.

However, we may send you a temporary My Account for individuals access code by text or automated call, but only if you ask us to. We also send automated emails to notify you of a new message in My Account for individuals, My Account for businesses or My Account for professional representatives, but these emails do not contain any confidential information.


If you receive an email that seems suspicious because personal information is requested, delete it immediately to avoid disclosing confidential information by answering an email that appears to come from our organization. When in doubt, do not reply.

Make sure you are on our official site

Scammers may create links to a site that seems legitimate and that is accessible with a simple search. An Internet user doing a search may click a link provided by the search engine and unintentionally browse on the fake site.

To avoid such a situation, make sure that the address (URL) shown in your browser's address bar is our distinct official address, which is You can also type in the address yourself. 
Our online services are secured by the TLS protocol. When you use the services, make sure your connection is secure (that there is a valid security certificate).

Use a firewall

We recommend that you install a firewall on your computer and make sure it is set up properly. A firewall helps prevent unauthorized access to or from your computer by filtering information coming through the Internet connection into your computer. It will allow only connections that are known and trusted.

Use anti-virus software

Your computer can become infected with a virus as a result of the vulnerability of your operating system, through email attachments, or from free content you download from a website or other media that someone shares with you (e.g. USB flash drive). By installing anti-virus software on your computer, you reduce the risk of infection. The anti-virus software can detect and get rid of viruses so that they do not damage your computer or spread to other devices.

End your session correctly

Once you log in, do not leave your computer unattended. When you use an online service, end your session safely.

Use private browsing mode

The cache is a temporary memory that enables your Web browser to perform more efficiently by saving browser data locally on your computer.

Data saved in the cache memory are not encrypted. Using private browsing mode ensures that the data are automatically erased when you close your browser. Most Web browsers have a cache memory, but it may be labelled under a variety of names.

If your browser does not offer private browsing mode, we recommend that you manually erase the cache memory after each session in order to safeguard the confidential nature of personal information. This operation is especially important if the computer is shared with other users.

Close the browser

Once you have finished using an online service, close your browser. Closing your browser is the simplest and most secure way of ending your session. You can even set up your browser to delete all copies of Web pages stored on your hard drive when you close it, which ensures that your data cannot be accessed.
