A comparison of a sole trader and a limited liability company

Sole traders versus limited liability companies – differences and their practical implications

Choosing the legal form of a business is a fundamental step that determines the scope of liability, the method of taxation, opportunities for growth and the financial burden on the business owner. In Poland, the choice is generally between a sole trader (JDG) and a limited liability company (sp. z o.o.). The two forms differ radically in formal, legal, financial and organisational terms, which requires a thorough analysis before a decision is made.

1. The registration process and start-up costs

Registering a sole trader (JDG) simply involves an entry in the Central Register and Information on Business Activity (CEIDG), which can be completed entirely online, free of charge. The formalities are limited to submitting the CEIDG-1 application, and the process usually takes from a few dozen minutes to several days. In contrast, a limited liability company (spółka z o.o.) requires the drafting of articles of association, usually in the form of a notarial deed, followed by registration with the National Court Register (KRS). This process is more complex and time-consuming (taking from a few days to several weeks), and also involves costs: the minimum share capital is 5,000 PLN, plus notary fees (approximately 200–600 PLN), court fees (PLN 500 for entry in the KRS, PLN 100 for publication in the Court and Economic Gazette) and tax on civil law transactions (0.5 per cent of the share capital). An alternative is electronic registration via the S24 system, which is cheaper but limited to a standard form of contract and excludes non-monetary contributions.

2. Liability for obligations

In a sole trader business (JDG), the owner bears unlimited liability for the business’s liabilities with all their personal assets. The distinction between private and business assets is virtually non-existent, meaning that creditors can seize the entrepreneur’s personal assets, including property, savings and other assets. This arrangement carries significant risk, particularly in businesses involving heightened financial or legal risks.

By contrast, a limited liability company (sp. z o.o.) has legal personality, meaning that the shareholders’ liability is limited to the amount of their capital contributions. The company’s assets are separate from the shareholders’ personal assets. However, members of the management board may be held personally liable if they fail to fulfil their duties, for example, by failing to file for bankruptcy within the prescribed time limit (Article 299 of the Commercial Companies Code). In practice, such liability tends to apply to the management board rather than to the shareholders themselves. The limitation of personal risk is one of the most important advantages of a limited liability company.

3. Financial and tax matters

The main tax applicable to a sole trader is personal income tax (PIT). The sole trader may choose between taxation under the general rules (12% and 32% tax bands), a flat-rate tax (19%) or a lump-sum tax on recorded income (rates ranging from 2% to 17% depending on the type of business). A sole trader may use simplified accounting (KPiR or a revenue ledger), which reduces the costs of running a business.

A limited liability company (Spółka z o.o.) is subject to corporation tax (CIT) – 9% for small taxpayers (up to €2 million in annual turnover) or 19% in other cases. The company’s income is taxed at the company level, and any subsequent distribution of profits to shareholders (e.g. in the form of dividends) is subject to further personal income tax (PIT) at 19 per cent. However, double taxation can be mitigated through various optimisation mechanisms, such as remuneration for board members, property lettings or civil law contracts. It is worth noting that a limited liability company (sp. z o.o.) is required to maintain full accounts, which results in higher accounting costs (on average from PLN 500 per month upwards).

4. Social security and insurance contributions

An entrepreneur running a sole trader business is obliged to pay social security and health insurance contributions, the amount of which depends on income or the minimum wage. Young entrepreneurs can benefit from relief schemes such as the start-up relief (health insurance contribution only for 6 months) and preferential ZUS rates for 24 months. After this period, it is possible to opt for the ‘Mały ZUS Plus’ scheme. Contributions represent a significant financial burden, often exceeding 1,200 PLN per month.

In a limited liability company (sp. z o.o.), the situation is more varied. Shareholders who do not carry out any other business activity are not required to pay social security contributions, whilst members of the management board appointed by resolution without an employment contract pay only the health insurance contribution, the amount of which does not depend on income. This arrangement can significantly reduce insurance costs, particularly for those on higher incomes. However, a single-member limited liability company (sp. z o.o.), where the owner is also a member of the management board, is treated in the same way as a sole trader (JDG) for the purposes of contributions, which means the obligation to pay the full amount of contributions.

5. Accounting and financial transparency

A sole trader may use simplified accounting, which reduces administrative obligations and costs. Entrepreneurs often keep their own income and expenditure ledger (KPiR) or a record of income using online software.

A limited liability company (Sp. z o.o.) is required to maintain full accounts in accordance with the Accounting Act, to prepare annual financial statements and to publish them. Although this incurs higher costs, it ensures significantly greater financial transparency, which enhances the company’s credibility in the eyes of banks, investors and business partners, making it easier to secure financing, leasing or larger B2B contracts.

6. Ownership structure and management

A sole trader (JDG) is a business operated exclusively by a single person – the owner – who makes decisions independently. This structure ensures swift decision-making but limits the scope for collaboration and risk-sharing.

A limited liability company (Spółka z o.o.) may have multiple shareholders, and its operations are governed by the articles of association. Provisions regarding the distribution of profits, responsibilities, representation and management are set out in the articles of association, which allows for flexible and transparent management of the company. This is important when planning for growth, attracting investors or succession.

7. The possibility of sale and succession

A sole trader is not a separate legal entity, which makes it impossible to sell the business as such – only assets or rights to contracts can be sold. Succession following the death of the sole trader is complicated and requires additional formalities, such as the appointment of a succession administrator.

A limited liability company (Spółka z o.o.), as a legal person, may be traded – shares may be sold, which allows for the easy sale of the business or the introduction of new shareholders. Succession is simpler, and the company’s structure allows for a smooth takeover of control of the business.

Summary and recommendations for entrepreneurs

The decision between a sole trader business and a limited liability company (Sp. z o.o.) should be based on an analysis of individual needs, the scale of the planned business, financial expectations and the acceptable level of risk. A sole trader is characterised by simplicity of registration, lower start-up costs and simplified accounting, which makes it attractive to micro-entrepreneurs, freelancers and those testing the market.

A limited liability company (sp. z o.o.), on the other hand, offers limited financial liability, greater opportunities for tax optimisation, enhanced credibility in business dealings, and flexibility in management and collaboration. It is the preferred form for companies planning to expand, take on staff, attract investors or take out bank loans.

It is worth noting that the tax and social security contribution changes introduced by the Polish Deal, as well as further regulations due in 2025, affect the cost-benefit calculations for both forms. Before making a decision, it is advisable to consult a tax and legal adviser who will take into account the specific nature of the industry, financial forecasts and the entrepreneur’s individual objectives.
