Registration of sole proprietorship in Poland: step by step

Registration of sole proprietorship in Poland is the first step for those who plan to work for themselves, provide services, or sell goods without creating a company. Properly оформленный статус przedsiębiorca guarantees the legality of activities, access to the social insurance system (ZUS), the ability to enter into contracts with counterparties, issue invoices, as well as benefit from tax privileges and simplified accounting forms.

This material discusses the step-by-step procedure for registering a sole proprietorship: from preparing the necessary data and choosing PKD codes to submitting an application online or directly at the commune, as well as further actions regarding registration with ZUS and determining the form of taxation. The article is aimed at foreigners, particularly citizens of Ukraine, who plan to start a business in Poland, and will help avoid typical mistakes and delays at the start.

The preparatory stage of registering a sole proprietorship in Poland is the choice of PKD code and legal address.

At the start, it is important to determine exactly what you will be doing and fix it through codes. PKD. They describe the main and additional types of activities and affect taxation, the possibility of obtaining licenses, and participation in government programs. It is recommended to highlight one main code that will reflect the main share of income, and several additional ones for future development — it is more difficult to add a new PKD later than to choose it in advance. Before submitting the application, study the descriptions of the codes in the official register, compare the formulations and exceptions to avoid choosing too narrow or, conversely, overly general types of activities.

  • Main PKD — the activity that brings the highest turnover.
  • Additional PKD — additional services or goods that you plan to offer.
  • Legal address — the place where the company is registered and where correspondence is sent.
  • Documents for the address — lease agreement, owner's consent, or property documents.
Address option Features When it is suitable
Home address Minimal expenses, access to mail is needed Freelance, online services
Rented office Separate room, image, client reception possible In-person reception, team, warehouse
Virtual office Secretariat, mail forwarding, contract for the address Startup, niche testing

When choosing a legal address, consider not only the cost but also practical aspects: stable access to paper correspondence, the possibility of actual use of the premises, and the absence of restrictions from the tenant or management company. Mistakes at this stage can lead to missed letters from ZUS or the tax office, which can result in fines and unnecessary visits to institutions.

Submitting the CEIDG application online or in the commune practical recommendations and typical mistakes

When choosing the method of submitting the CEIDG-1 form, it is important to prepare all data in advance: current PESEL, address of residence and business activity, codes PKD, phone number and e-mail. When registering online through Biznes.gov.pl or the CEIDG website, check which identity verification option you are using: trusted profile, e-ID or qualified signature. At the commune (Urząd Gminy/Urząd Miasta), bring an identity document, preferably a printout of the prepared draft application, and a list of questions for the staff. It is also worth considering the hours of reception for entrepreneurs and possible queues.

  • Incomplete or inaccurate data — mismatch of address, incorrect PESEL, incorrect PKD code.
  • Incorrect start date of activity — indicating a past date without considering tax consequences.
  • Ignoring the choice of tax form — leaving it as default without consulting an accountant.
  • Lack of an up-to-date online authorization method — unprepared profil zaufany or expired certificate.
  • Errors in contact details — incorrect e-mail or phone complicate communication with ZUS and the tax office.

Registration in ZUS and the tax office, choice of tax form and insurance contributions

After registration in CEIDG, the entrepreneur's data is automatically sent to the tax office and ZUS, however, at this stage, you need to make several key decisions. Within 7 days from the start of activity, you should submit the relevant forms to ZUS (usually this is ZUS ZUA or ZUS ZZA) and determine whether you will use preferential programs, such as „start relief”, „small ZUS” or standard contributions. At the same time, it is important to notify the tax office about the chosen form of taxation by submitting an application (for example, ZAW-R or updating records in CEIDG) to avoid automatic default assignment. The most common form is general principles (tax scale), but for some types of activities, it is more profitable tax at a linear rate or lump sum.

When choosing a tax regime and insurance contributions, it is worth assessing the expected turnover, expense structure, and business development plans in advance. For convenience, you can refer to the following benchmarks:

  • Tax scale — suitable if you plan high expenses and possible tax benefits (children, joint taxation with a spouse).
  • Linear tax — interesting with high incomes and relatively low expenses, but without the right to most personal benefits.
  • Lump sum — convenient for freelancers and services with low costs, where simplicity of accounting is important.
  • Start relief / small ZUS — temporarily reduces social contributions, but affects the future amount of pension and benefits.
Option Advantages What to pay attention to
Tax scale Benefits and deductions, progressive rate Higher tax on high income
Linear tax One percent for all incomes Without most personal benefits
Lump sum Simple accounting Actual expenses cannot be deducted
Start relief / small ZUS Low start-up contributions Smaller base for future benefits

Organization of settlements and document flow, opening a bank account, accounting, and document storage

After entering the record in CEIDG, the first practical step is to choose a servicing bank and open a separate account for business activities. Although in Poland, an individual entrepreneur can formally use a personal account, in practice it is recommended to allocate a separate settlement account, to simplify control over cash flow, preparation of declarations, and interaction with the tax office and ZUS. When choosing a bank, it is worth comparing fees, access to online banking, integration with popular accounting systems, and the availability of support in Russian or English.

  • Separate accounting of personal and business funds
  • Timely processing and archiving of invoices
  • Electronic document flow with the tax office and ZUS
  • Regular backup accounting data
Document Minimum retention period Form
Invoices (VAT/without VAT) 5 years Paper or electronic
Contracts with counterparties Until the expiration of liability + 3 years Paper
Payment confirmations At least 5 years Electronic bank statement
Reports for tax and ZUS 5–10 years (depending on the type) Electronic via ePUAP / PUE ZUS

To optimize work, it is advisable to set up a structured document storage system from the very beginning: separate folders for contracts, invoices, bank statements, and correspondence with authorities. This can be either a physical archive or a cloud storage with regular backups. Using software for invoicing and simple online accounting facilitates the control of tax payment deadlines, the generation of reports, and reduces the risk of errors, especially when working under complex tax regimes. A well-organized accounting and document flow allows the entrepreneur to focus on business development rather than correcting formal shortcomings.
