As everywhere else in EU (and unlike the UK), filling taxes and registering employees for all the necessary insurances and gov agencies becomes an extreme burden as soon as you go beyond just one person / the simplest business transactions. It's a fulltime job even if the company is still very small and just doesn't have the resources to hire a fulltime dedicated person.
Uhm... usually if you go beyond 1 person then you get someone to handle all the paperwork and this applies to almost all countries... In case of Poland it's not all that expensive either, especially if it takes off of you the burden...
No, not really. I can't make the money to hire the person to handle it without first having the employees. I handle it all myself, I am not VC-funded nor eligible for incentives.
