Not sure what you mean by "taxable days." Tax is based on earnings not days worked.

If you work in the US and live in Canada, you need to file a 1040NR with the IRS.

When i am in the USA i Pay US tax because im there in there country but when i travel home i am in my country Canada still getting payed until i reach my home so while in Canada getting payed do i pay Canadian tax USA tax Days in Canada getting payed is only around 6-8 days per year

like this i leave 6 pm on a monday from USA get home 3am on Tuesday i am payed in full for Tuesday so is it taxable to canada or USA ??

Thanks

taxes are based on residency. If you are paid by a US company in US dollars but you live in Canada then you would have to file both Canadian income tax and US income tax. If you make more than $87,000 (give or take) then you would have to pay taxes in the US as well as Canada, but if you make less than that, you pay only Canadian taxes.

As ax said, for the US income tax report you have to file 1040NR form to the IRS.
