Revenu Québec ensures that information exchanged through its site is secure in order to preserve confidentiality.
The security mechanisms that we have put into place for our website are effective only if you follow certain basic rules
We use the TLS protocol to ensure the confidentiality and integrity of data transmitted between your computer and our servers. Our site supports versions 1.0, 1.1 and 1.2 of this protocol.
The TLS protocol transforms your data into an encrypted code so it cannot be read during transmission. The encrypted data is converted back into readable data when it reaches its destination. In short, encryption converts information into a secure format for sending.
When using our online services, please follow the recommendations below.
Keep your browser up to date
Although most recent browsers have protection features, we advise using the most recent version of your browser and checking that the browsing options in the new version are set how you want. In addition, if you receive a message announcing a new version of your browser or a security update, make sure to install it.
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 www.revenuquebec.ca. You can also type in the address yourself.
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.
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 antivirus software
Your computer could be infected by a virus due to a weakness in your operating system or through email attachments, content you download from a website or through other information you share with someone (using a USB key, for example). You reduce the risk of infection by installing antivirus software on your computer. Antivirus software detects viruses and eliminates them so they do not spread to other devices or damage your computer.
Close your session correctly
Do not leave your computer unattended after logging in. In addition, after using an online service, close your session by clicking on the logout button, not just by clicking the X located in the upper right corner of your browser.
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.
