I moved from Canada to the US in Summer of 2016, this Summer we are planning to move home. My wife's PR application is relatively near completion. I'm concerned about my credit score and taxes. I read I wouldn't have a credit score when returning home, but in fact since I've been gone my Canadian credit score has increased. I do have a Canadian bank account where I'm moving our savings for the move, and since I've been gone I've intermittently used my Canadian credit cards on trips home etc. Is this going to cause a problem in terms of my taxes? I paid income tax on the last year I was there, and started paying taxes in the US when I started working in 2017. My SSN is currently dormant. So as far as I understood I am a non Canadian resident for tax purposes, I do not have any income sources in Canada nor have I since I moved. So is it okay that I've had the bank account and credit cards still open? Will my credit score still be valid when we return? Thanks for any help, or resources anyone can point me to.
