The opening of jednoosobowa działalność gospodarcza begins with verification of the right to do business. Registration with CEIDG, choice of tax regime and obligations to ZUS are related but separate stages; admissibility of JDG depends on the alien's status and applicable regulations.

Before registration, you need to define your activity, estimate expenses and responsibilities, check the tax form and conditions of possible benefits. There is no universal beneficial option for everyone. Promotional offers from intermediaries and unconfirmed promises of savings have been removed; practical recommendations are kept in draft until the official conditions are verified.
