Canada USA tax filing 2025

Hello all,

I am a Canadian citizen and was resident of Canada up until July 31, 2025. Since then I have severed ties with Canada and been living and working in states. As the calendar year is coming to an end soon, I would like to understand how tax filing will work in my case.

Will I be filing taxes in both Canada and United States? Am I required to report my 2025 USA income in Canada and pay difference of the taxes (as tax rate in Canada is higher than States).

At some point I will be speaking to cross border tax accountant but just wanted to get some input from folks who have been in Similar situations. Do I need to max out my RRSP contribution?

Thanks in Advance.
