Poland remains one of the most popular destinations for starting a business among foreign entrepreneurs – convenient logistics, access to the EU market, and a relatively simple registration procedure all play their part. But right from the start, many run into a surprise: accounting here works quite differently from what they're used to back home. The record-keeping formats are different, the reporting is different, and even communication with the tax authority follows its own logic. And 2026 is becoming a turning point on this front – the country is gradually moving businesses onto mandatory electronic invoicing.

It's worth figuring out these rules before your first deal, not after the tax office issues a back-payment demand or a late-filing penalty. The key differences are explained to relocate.to by Iryna Kachmarchyk, managing partner at the accounting firm CeDePe, which supports businesses across several jurisdictions at once.

Running a business abroad almost always comes with questions that are hard to sort out without a specialist – from choosing a legal form to labor disputes or dealing with the tax office. 

A personal business lawyer takes on exactly these tasks: advising on registration, document flow, reporting, and minimizing tax risks, and, if needed, supporting the company during a relocation to another country. This isn't a one-off consultation but ongoing support you can turn to at any stage of your business's growth. Find a personal lawyer for your business on Visit World right now. 

How is accounting in Poland different from what you're used to?

The first thing an entrepreneur runs into is the choice of accounting format. A sole proprietorship (JDG, the Polish equivalent of a sole trader) keeps either a simplified revenue ledger (ewidencja przychodów) or a tax book of revenues and expenses (PKPiR), depending on the chosen tax system. A limited liability company (spółka z o.o.), on the other hand, is required to keep full accounting books (księgi rachunkowe) – a whole different level of complexity and responsibility.

The second point is digitalization. Polish businesses interact with the state through separate electronic systems, the key one being the Krajowy System e-Faktur (KSeF), the national platform for electronic invoices. Alongside it sits JPK_VAT – a single control file through which VAT payers submit structured data on their purchases and sales, together with the declaration section, to the tax office every month.

And the third is the country's own rules for handling transactions: issuing invoices, calculating and accounting for VAT, payroll and HR records, and interaction with government bodies. Each of these processes needs to be set up according to Poland's own requirements rather than the logic you're used to at home.

Mandatory KSeF: who switches to the new system, and when

The biggest upcoming change is the phased rollout of mandatory KSeF use. As of February 1, 2026, the largest companies – those with 2024 turnover exceeding PLN 200 million – joined the system; from that point on, all entrepreneurs, regardless of size, are required to be ready to receive invoices through KSeF. As of April 1, 2026, the obligation to issue and receive invoices through the system extends to the vast majority of other entrepreneurs.

The smallest companies remain an exception for now – those whose monthly invoiced sales don't exceed PLN 10,000 (with a PLN 450 cap per individual invoice). For them, the transition is postponed until January 1, 2027, although they will also have to start receiving incoming invoices through KSeF earlier. In B2C sales – transactions with private individuals – using the system remains voluntary.

VAT and reporting: the logic and the deadlines

In economic substance, Polish VAT is close to the VAT entrepreneurs are used to, but the administration process is quite different. The main reporting tool is the already-mentioned JPK_VAT, which combines the purchase and sales registers with the declaration section in a single file. Active VAT payers submit it monthly, by the 25th of the following month – and this rule applies even to those who technically settle with the tax office on a quarterly basis.

Employees and ZUS

If a company plans to hire staff in Poland, it will need to set up a separate HR and payroll process. The employer registers employees with the Zakład Ubezpieczeń Społecznych (ZUS) – the social insurance institution – calculates contributions, and transfers them every month. Part of the contributions is covered by the company, part is withheld from the employee's salary; the exact split depends on the type of insurance.

Poland is launching a new phase of labor-market controls in 2026, tightening checks on employment contracts and working conditions – details via the link.

Checklist: what to think through before you start

Before moving to regular operations, it's worth walking through the entire future accounting process on paper and pinning down the answers to a few questions:

- which business form and tax system to choose;

- which accounting format that specific form of activity requires;

- how to set up issuing and receiving invoices through KSeF;

- whether VAT and JPK_VAT obligations arise;

- how to organize HR records and ZUS contributions if there are employees;

- which software to use, and whether it integrates with the government systems;

- who exactly prepares the documents, checks the transactions, and hands them off to the accountant.

This approach lets you set up your accounting correctly from the start – instead of restructuring the system later, once you're already operating and the cost of a mistake is higher.

Is it mandatory to hire a Polish accountant?

No. Polish law doesn't require an accountant to hold Polish citizenship or residency – what matters is that the specialist knows the local accounting and reporting rules and meets the requirements for providing accounting services. So a specialist from another country can perfectly well support a Polish business.

Some companies still hire accountants directly in Poland, since they're well versed in the local system. But if the business also operates in another country at the same time, coordination between the two accounting teams has to be set up separately, which adds organizational overhead. An alternative is to outsource accounting to a firm that already operates in both jurisdictions – that way there's no need to hire a second accountant or manually coordinate two teams.

Accounting in Poland isn't necessarily more complex than what an entrepreneur is used to at home – it just runs on different rules and different tools. And the sooner these rules are adapted to a specific business – invoicing, VAT, reporting, HR – the fewer mistakes there will be to fix after launch.

Adapting your accounting is just one part of what a business faces when entering the Polish market. In parallel, you have to deal with company registration, choosing a tax system, formalizing employment relationships, and interacting with local authorities – and a mistake at any of these stages can cost time and money. 

A personal business lawyer helps you get through this process without unnecessary risk: advising on registration and the choice of legal form, supporting document flow and reporting, and handling disputes with counterparties or authorities. If the company plans to hire employees or arrange work visas, the specialist can help with that too. This kind of support is especially valuable during a business relocation abroad, when you have to deal with a new jurisdiction while keeping day-to-day operations running. Turn to a personal business lawyer on Visit World and protect your company from the typical mistakes of entering a new market. 

A reminder: registering a business doesn't automatically grant you the right to reside in Europe. We've already covered how this works in Poland, Slovakia, and Spain in 2026.
