Browser requirements

Your browser must have:

  • Transport Layer Security (TLS) 1.2 or higher, turned on
  • Cookies turned on
  • JavaScript turned on

Any up-to-date version of Chrome, Edge, Firefox or Safari meets these. If your browser or device is old, update it first.

The CRA uses persistent cookies for sign-in. According to the CRA, they don't store any identifying data.

Is it the site, or your account?

If the page loads but your details are refused, the site is working and the problem is your sign-in. Use the CRA sign-in troubleshooter to find the fix.

If you see a message that your account is locked, read CRA account locked.

Step by step

  1. Check the time.

    CRA sign-in services are available 21 hours a day. They are offline every night between 3 am and 6 am Eastern time. That is midnight to 3 am in British Columbia.

  2. Check for a maintenance weekend.

    The CRA also takes its digital services offline on some weekends. The dates are in the table below.

  3. Refresh the page, or try another browser.

    If one browser keeps failing, a different browser or device often works.

  4. Clear your cache, cookies and history.

    Old saved data is a common cause of loops and blank pages. Then restart your computer and try again.

  5. Switch from Wi-Fi to mobile data.

    The CRA suggests this when a network blocks or interrupts the sign-in.

  6. Still stuck? Contact the CRA.

    Call 1-800-959-8281, Monday to Friday, 8 am to 8 pm Eastern time.
