lots and lots
you will definitely need an attorney, for starters.. polish bureaucracy is a bltch.
Don't be ridiculous. An attorney, for a sole trader? You must be joking!
How long would it approx. take to fullfill the formalities and what is the cost price for that?
About 2-4 weeks for everything to come through, cost - nothing.
- Nip (what comes first? I guess NIP ?)
Any other bureaucratic hurdles to overcome?
I already live six years here (EU citizen, pobyt na stale) but this company stuff is new to me..
It's pretty simple -
If you don't have a NIP, go to the Urzad Skarbowy and apply for one.
Go to the relevant place in Warsaw where they register new sole traders.
Fill in the form, then hand it in. You'll be told when to come back (usually within a few days)
Go back and they will give you some documents. You'll be told to wait for the REGON to come through the post. When that arrives, go to a friendly accountant (you'll need one, but you can get a good one for 150zl a month easily) who can handle everything with ZUS.
You'll also have to go to the Urzad Skarbowy to fill out some basic form about how you want to pay taxes and which tax scheme you want to use. An accountant will advise you on this if you don't know what to do :)
It is very, very painless - but I advise the use of an accountant to deal with ZUS as the accountant should take responsibility.
