Hi NOC98,I got my new SIN in Feb and used that to file my 2020 income tax return with no problems. I also created a new CRA account as my previous account with old SIN via partner login has been deactivated already and cannot be used. My new CRA has my old tax filing with my wp SIN.
There’s no need to inform CRA of your new SIN as service Canada sends that info to CRA.
How did you create your new CRA Account? Can I create it using same sign-in partner as the previous one?
I got a new SIN but in this link https://www.canada.ca/en/revenue-agency/services/e-services/e-services-individuals/account-individuals.html there is only option to click and Sign-in with Sign-in Partner. Thank you
