Easily - two trips to the Urząd Miasta, one trip to the Urząd Skarbowy and the job's done.
Or in Warsaw one trip to the Urząd Miasta, a trip to the tax office then to Główny Urząd Statystycne, and trip back to the tax office. If it's a one man band your last tasks will be a visit to ZUS and to get a rubber stamp made while-U-wait.
Don't let Poles befuddle you with stories about it being complicated, remember you need to know what type of accounts you are going to keep (choose the easiest), remember that three tax officials will have four different answers to the same question which they will each swear on their life is right - choose whatever answer suits you best and take a good book with you - there's a lot of waiting in corridors.
If it's a limited company however procedures are a little different. Perhaps even simpler, but you need to register it with the court and sign the articles of incorporation at a notary and with a sworn translator.
t's crucial to get the right accountant. A bad one can completely screw you up
Yes. People have gone bust due to a bad accountant (bookkeeper is more accurate but they always say accountant) - many of them in PL don't understand their role - they see themselves as some sort of intermediary between the business and the state and actually refuse to do the client's bidding.
It is vital to get a good one. When I started up I had a bookkeeper who booked the first two months of 100k plus billing as well as the start-ip capital into the same month and all the salaries and overheads into a subsequent month showing a 250000 zl pre-tax false profit. For only two months and the tax bill due right away. She swore blindly (and loudly) that this was right and is "how we do it in Poland".
The old bi tch nearly busted the company and made 40 people unemployed and the financial analyst I had to get in to sort her mess out it out "isn't Polish so can't understand".
