It is temporary and just for one employee, not going to be more in the near future, so as minimal configuration as possible would be best.
He is going to remain on the Canadian payroll and he still has CDN benefits, CPP, EI and owes CDN tax for the time he works in Canada. He does need to have US Federal tax and CT tax withheld for most of his time.
Is there a somewhat simple way to input this for him so we can remit and report to the US correctly?
