If you didn't legally change your last name, you do not have to change your last name to your husband's last name at CRA.Upon updating my marital status with CRA online, do I also need to change my last name? 'cause when I updated the status online I only change the SINGLE to MARRIED but my last name is still showing my maiden name...
You have a choice! However, if you choose to take your husband's last name. Look into information provided in your province and see what steps you need to take to take his last name.
