Selling on Amazon US from Canada

Can anyone suggest if I’m doing Amazon FBA from Canada selling in Usa do we have to pay sales tax and where? Any leads for accounting?

Thanks

In USA marketplace different states have different tax policies that’s why Amazon collect tax and submit it to relevant state. But you need to file return, for this purpose you can contact an accountant.

Being in Canada and selling in Usa I just need to submit returns and not deposit tax right?
