Setting up a sole proprietorship (JDG) in Poland is free and mostly possible online. That does not mean, however, that it is a decision to rush. A few choices made at the registration stage — above all the form of taxation and VAT status — affect the level of your burdens over the following months, and sometimes for the entire tax year. Below we walk through the successive steps and point out the places where a costly mistake is easiest to make.
Step 1. The CEIDG application
Registering a sole proprietorship is done by an entry in the Central Registration and Information on Business (CEIDG). The application can be submitted electronically using a trusted profile (profil zaufany) or a qualified signature, or in person at any municipal office. A single form handles several matters at once: it registers the business and reports it to the tax office, to the social insurance institution (ZUS) and to the statistical office (GUS) for a REGON number. A NIP number, if the entrepreneur does not yet have one, is assigned automatically.
The application includes, among other things, the company name (which must contain the entrepreneur's first and last name), the address of the activity, the expected start date and contact details. It is worth remembering that the start date can also be set in the future — this is useful when you want to properly plan the start and the moment your ZUS obligations arise.
Step 2. Choosing PKD codes
PKD codes (the Polish Classification of Activities) specify what the business will do. You indicate one main code — corresponding to the predominant activity — and any number of additional codes. The choice of codes is worth thinking through more broadly than just today's plans: adding a few related areas in advance costs nothing but saves a later update of the entry when the activity develops.
The PKD code also has practical significance beyond statistics. Some types of activity are excluded from lump-sum taxation or subject to different rates, and some require additional permits or licences. That is why the choice of codes is best consulted before submitting the application.
Step 3. Form of taxation — the most consequential decision
A sole proprietor has three basic forms to choose from: the tax scale (12% and 32% above the threshold), the flat tax (19% regardless of income) and the lump-sum tax on recorded revenue (rate depending on the type of activity). There is no single best form for everyone — the choice depends on expected income, the level of costs, the industry and family situation (e.g. the possibility of joint settlement with a spouse).
Since 2022 the cost of each form is additionally affected by the health contribution, calculated differently depending on the chosen taxation. Under the scale it is 9% of income, under the flat tax 4.9% of income, and under the lump sum a fixed amount depending on the revenue threshold. This makes comparing the forms without specific figures often misleading. In practice the same activity profile may turn out most favourable under the lump sum or under the scale — it all depends on the ratio of revenue to costs.
Step 4. VAT — register or use the exemption
Many new entrepreneurs can use the subjective VAT exemption as long as the annual sales value does not exceed the statutory limit. The exemption simplifies accounting and is often attractive for activity aimed at individual customers. On the other hand, VAT registration allows you to deduct tax on purchases, which pays off with larger initial investments or when the main customers are active VAT payers.
Some types of activity are excluded from the exemption and require VAT registration from the very first transaction. That is another reason to settle your VAT status before starting sales rather than after the first invoices.
Step 5. Registering with ZUS and the first contributions
Submitting the CEIDG application alone reports the business to ZUS as a contribution payer, but does not yet register the entrepreneur for specific insurance. That is a separate form (ZUS ZUA or ZUS ZZA), which must be filed within 7 days of starting the activity. This step also decides whether you use contribution reliefs — the start relief, preferential ZUS or Mały ZUS Plus — which we cover in more detail in a separate article.
What is not visible at first glance
Registering a business is a formality you can complete in one evening. Harder — and more important — are the decisions that this formality locks in: the form of taxation is generally binding for the whole year, VAT status affects prices and margins, and the choice of ZUS relief shapes the level of future benefits for years. It is good to calculate several scenarios in advance rather than correct them later.
