Law / Tax to Poland from US non resident company [9]

I want to set up a company in Delaware, US as a non resident.

(The business will be book publishing online, and paid membership sites)

Anyone who have done this, living in Poland? (I'm living in Poland, but I'm not Polish)

I will not be doing any business in the US, I'm merely interested in setting up a company in a country that everything is in English (as I do not speak any Polish). And eventually I will want to move there.

Do I have to register myself as self-employed in Poland, to run a business in US? Will I have to hire an accountant in Poland, and how much will this cost me per month? (total cost per month of being self employed and paying for an accountant). I guess all the tax papers in Poland are in English, so I'll need someone to deal with the paperwork?

And I guess I have to pay tax to Poland, since I live there, and will have a company with income, even if it's based in the US?

Or is this a lot more simpler than I expected? Like, can I just pay tax to the US, and not have to deal with the Polish tax office at all?

Thank you for your time and attention, and I really appreciate you looking into this for me. Hope to get some really positive replies soon :))))))))))))))))))))))))))))))))))

Law / Sell my books as private person? Tax question [8]

I'm writing books, and I want to sell them online on my website or through Amazon.

Is it really necessary that I register as self-employed?

I would really appreciate if someone would explain this to me, and tell me about my options :)

I live in Poland, but I'm not Polish. I do not work in Poland, or have any income in Poland, but I have a Polish tax number.

Law / Do I really need an accountant when I'm self-employed? [16]

I want to sell my books online, and have a paid membership website.

Can anyone tell me if I need an accountant for this, or if I can do this myself? (I do not speak or write any Polish) I will not have any employees.

I would really appreciate it if someone took the time to explain this to me, how to become self-employed, what I have to register, and when and where, and how much everything will cost from month to month :)

Law / How to find a Poland-located company's registered address? [7]

If I want to check where a company (self-employed) has it's registered address, how do I do that?

Can I find this information online, and how much up to date would this information be?

What other information can I find about a self-employed person? And on what sites can I find this info?
