Accounting in Poland, briefly and to the point – There are 2 main accounting systems in Poland: simplified (Księgowość uproszczona) and full (Pełna księgowość). – KSeF (the national e-invoice system) is already mandatory, not “coming in 2024”: since February 1, 2026 for large taxpayers (2025 turnover over PLN 200 million including VAT) and since April 1, 2026 for all other VAT-registered taxpayers; the smallest taxpayers (monthly sales up to PLN 10,000) have until January 1, 2027. (Corrected: the original said the system “will be introduced” in 2024; it was delayed twice and only became mandatory in 2026.) – A tax offense fine ranges from PLN 480.60 to as much as PLN 46,137,600, based on the 2026 minimum wage (PLN 4,806/month, flat all year). (Corrected: the original cited 2024 minimum-wage-based amounts, PLN 1,414-40,723,200.) – Since 2014, one no longer needs a Ministry of Finance certificate to work as an accountant, and this fact itself is unchanged and still correct. – Karta podatkowa (tax card), mentioned below as one of three simplified accounting options, has been closed to new taxpayers since January 1, 2022 (Polski Ład reform), and it survives only for those who already used it before that date. (Corrected: the original listed it as a normal option available to anyone.) – It’s important to find an accounting firm with experience in your specific field.
Poland represents a field of opportunities for entrepreneurs due to its dynamic economy and entrepreneurial environment, predominantly in the IT field. However, successful business conduct requires strict compliance with local legislative and regulatory acts, especially in the field of legalization and accounting. Based on our experience, we can affirm that taxpayers have found it difficult to navigate the multitude of tax innovations and rules, and 2026 is no exception, mainly because of the KSeF rollout and the ongoing PIP 2026 labor-law reform affecting B2B contractors (see below).
Therefore, we strongly recommend using the services of an accountant who has experience working with companies in the same field as you do, is fluent in Polish, and is up to date with new requirements for accounting and taxation.
In this article, we will consider the key aspects of accounting specific to IT entrepreneurs in Poland, and discuss the advantages of freelance accountants and accounting outsourcing, as well as the nuances entrepreneurs face.
Accounting report for Individual entrepreneurs in Poland
There are two main accounting systems in Poland: – simplified (Księgowość uproszczona); – complex (colloquially called księgi rachunkowe or pełne księgi).
The simplified system is suitable for small businesses and individual entrepreneurs, while the complex system is suitable for large and medium-sized companies. Both formats have their own features, and when choosing between them, consider the unique needs of your business, forms of activity, and annual turnover of funds.
Simplified accounting does not require keeping a full accounting book, and allows the use of simple solutions for registration and submission of financial reports to tax inspections. It comes in these forms: – Revenue and expense book (księga przychodów i rozchodów); – Fixed rate (ryczałt ewidencjonowany); – Tax card (karta podatkowa): only for taxpayers who were already using it before January 1, 2022; closed to new registrations since then under the Polski Ład reform.
The main limitation of using simplified accounting is the statutory revenue threshold (including tax amount) from the sale of goods, products, and financial operations for the previous financial year, which is equivalent to 2,000,000 euros. Exceeding this threshold requires full accounting. This threshold itself is unchanged and still current in 2026.
You can voluntarily choose complex accounting, and some entrepreneurs are required to keep it in accordance with current legislation. Full accounting is mandatory for limited liability partnerships, limited liability joint-stock partnerships, joint-stock companies, and limited liability companies (regardless of turnover), as well as other companies that reached income of at least 2,000,000 euros per year. According to the Income Tax Act and the Accounting Act, the corresponding conversion of the 2,000,000-euro limit into zlotys is based on the average exchange rate announced by the National Bank of Poland on the first working day of October of the previous year.
More about tax systems for sole proprietors we talked about here. If you run your business as B2B for a single client, also check our new series here: since July 8, 2026 the Labor Inspectorate can reclassify a B2B contract as employment, which changes your accounting and ZUS picture overnight.
All entrepreneurs need to understand that their accounting must meet the requirements not only of local, but also European legislation. The annual report and balance sheet are the main components of accounting reporting, which should include data on income, expenses, and tax liabilities.
Individual entrepreneurs and firms are obliged to submit reports in accordance with established deadlines to avoid fines and negative consequences.
KSeF is already mandatory, not a future plan. The national e-invoice system (Krajowy System e-Faktur, KSeF) rollout, originally planned for 2024, was postponed twice. As of 2026 it is mandatory: since February 1, 2026 for large taxpayers (2025 turnover over PLN 200 million including VAT), and since April 1, 2026 for all other VAT-registered taxpayers established in Poland. The smallest taxpayers (monthly sales not exceeding PLN 10,000, issuing low-value invoices) have until January 1, 2027. From these dates on, most B2B invoicing goes through the KSeF platform.
It is important to note that KSeF does not check invoices for errors or duplication, so companies need appropriate verification mechanisms of their own when implementing this system.
Main features of accounting for sole proprietors (JDG)
A key point is to comply with tax obligations. Proper accounting ensures timely and accurate tax payments. Non-compliance with deadlines or errors in reporting can lead to financial audits, criminal liability, and loss of trust from administrative authorities.
Financial transparency should not be neglected, as it is an important indicator when interacting with partners, investors, and banks that assess the financial condition of your business.
Fines for tax offenses and tax crimes vary and depend on many factors, including the current minimum wage.
For tax offenses (wykroczenia skarbowe), a fine can be imposed within the range of one-tenth to twenty times the minimum wage. If the action that led to a reduction in public tax revenues does not exceed five times the minimum wage, it is treated as an offense rather than a crime.
2026 figures (corrected from the original 2024 figures). The minimum wage in 2026 is a flat PLN 4,806/month all year (no mid-year increase, unlike 2024). This puts the fine for a tax offense in the range of PLN 480.60 to PLN 96,120.
For tax crimes (przestępstwa skarbowe), the court determines the number of daily rates and the size of one daily rate, taking into account the offender’s income, personal circumstances, and financial situation. The daily rate cannot be lower than one-thirtieth of the minimum wage, nor exceed 400 times that amount. In 2026, that means a daily rate of PLN 160.20 to PLN 64,080. With the statutory range of 10 to 720 daily rates, the final fine for a tax crime in 2026 can range from PLN 1,602 to PLN 46,137,600.
What accountant is considered to be a professional?
Until 2014, one could only work in the field of accounting after receiving a certificate issued by the Ministry of Finance, confirming sufficient qualifications and experience as an accountant and auditor. This deregulation is unchanged and still accurate: since 2014, no such certificate is legally required to practice.
Accountants certified by the Ministry of Finance before the 2014 deregulation, who hold such a certificate, confirm their qualifications and at least 10 years of experience as an accountant and auditor in Poland.
Such a specialist is capable not only of efficiently managing your finances but also of providing expert advice. This can help avoid undesirable situations and minimize risks for your business.
The language barrier can also be a problem, so it is important to ensure the presence of an interpreter or accountant with the necessary language skills. One of the important aspects is the difficulty in interpreting tax legislation, regular changes in tax policy, and limited resources to maintain up-to-date knowledge in this area. That’s why Moja Firma constantly invests in training its specialists, as well as in other, often digital, tools to make work easier.
Advantages of cooperating with a freelance accountant
For individual entrepreneurs and firms, an external accountant can become a reliable partner in conducting business. They will be responsible for the correct conduct of accounting, communication with the tax inspection and ZUS, and represent the company during tax audits. And here we are talking not only about fines, but also about precious time that the entrepreneur will save.
However, when choosing an outsourcing partner, it is important to pay special attention to their reputation and experience working with individual entrepreneurs in different IT spheres.
Moja Firma specialists have repeatedly confirmed their competence in conducting accounting and communicating with tax authorities. Having work experience, knowledge of local and international legislation, including transactions using cryptocurrency, as well as a tuned system and customer support, we have developed a package of services for comfortable accounting for our clients.
Both entrepreneurs and accountants without a focus on a particular industry are not efficient and often make mistakes that can be costly in the future. Our recommendation is as follows: if you manage a restaurant, turn to an accountant who works specifically with restaurants. If you are engaged in international and multicurrency IT, choose an accountant who deals only with this, for example, Polish specialists from Moja Firma.
We have the necessary knowledge and experience to ensure accurate and timely accounting, as well as quick consultation on any issues. We have implemented a customer support helpdesk system, which the client can use to ask questions, and our employees provide detailed answers through tickets.
Conclusion
The choice of a company that will assist you in accounting in Poland should, first of all, be based on the needs of your business, as well as on the competence of the accounting firm in a particular field. In any case, the key factor remains strict compliance with legislation and work with qualified specialists.
