Working remotely for a US company and seeking to live in Poland

Hello! I'm a US citizen, and for the last three years I have been continuously in Poland thanks to the US-Poland bilateral agreement which allows US citizens to spend 90 days in Poland, leave and immediately re-enter (without waiting 90 days outside the EU). I work for a US company remotely. Recently, I've been thinking about acquiring some sort of official resident status in Poland. In this regard, I have several questions:

1. Is it possible in principle that some sort of resident status would be available based on my work situation?
2. I would imagine if such status were available, I would need to start filing Polish tax returns. However, I am already being taxed in the US as W-2 employee, albeit a remote one. Would I be able to avoid double taxation, and if so, how?

Thank you so much!

You should have already been paying tax if you were here more than 183 days per year. Very small chance of getting caught though.

Yes there is a double tax arrangement with the US.

On the residency you might be best off to talk to a lawyer
