At this stage, it is useful to compile a short list of planned operations and correlate them with the descriptions of PKD, and in case of doubts, rely on the clarifications from KIS and the practices of similar entrepreneurs.

• Assess income stability: with fluctuating revenues, the progressive scale may turn out to be more expensive.
• Check the limitations: not all PKD allow the application of a flat rate, and for some types, there are special rates.
• Compare with development plans: a possible transition to VAT, hiring employees, and entering export markets should be considered in advance.
