Help!! How to update SIN to CRA?

[tango07]

Hi,
Need HELP.

Yesterday, I got my new sin number. People say that old cra account will be deactivated. But I can still login to my old cra account.

Will it take some days to deactivate old cra ?

Hi,
I have a same question, do you remember how many days it took for your old cra account to be deactivated?

Hi Everyone! I got PR 30 Jun 25. Same date I went to Service Canada and got an updated SIN. with my old SIN, I have partner sign in. Now still shows the old SIN and when I try to add a new account I keep getting error (using new SIN, DOB and Line15000 from TAX assessment) Should I wait more? or maybe I should use the old SIN? Not sure what I'm doing wrong. Tks!
