Year-End Closing in Poland for a Sp. z o.o. in 2026

Key deadlines for a Polish sp. z o.o. in 2026

For a company whose financial year ended on December 31, 2025, the main deadlines are as follows.

These dates assume that the company’s financial year is the same as the calendar year. If your company uses a different financial year, the same rules apply but the dates shift accordingly.

1. Financial statements deadline in Poland: March 31, 2026

The first stage is the preparation of the annual financial statements. For a company with a calendar financial year, this must be done no later than March 31 of the following year.

In practice, this usually means preparing at least the balance sheet, the profit and loss account and the notes or additional disclosures required for the entity. Depending on the size and status of the company, the scope of the package may differ, but it is still a formal year-end reporting obligation and not just an internal accounting exercise.

2. Financial statements must be approved by the shareholders by June 30, 2026

This point is often described too briefly. Approval of financial statements does not just mean that someone reads the numbers and agrees with them. From a corporate law perspective, the company must complete a formal approval stage by June 30, 2026.

In practice, this means that the shareholders of the company must hold a shareholders’ meeting, unless the matter is handled in another legally valid form allowed under the company’s documents and applicable Polish law. The outcome of that approval process must be properly documented.

As a minimum, the company should prepare a proper documentary package for the approval stage. In most cases this includes:

• minutes of the shareholders’ meeting, or a formal protocol documenting the approval process,
• a resolution approving the annual financial statements,
• a resolution on profit distribution or loss coverage,
• in many companies, resolutions on discharge of the management board members,
• where required, approval of the management report.

Without these documents, it is not correct to say that the financial statements have been properly approved. This is the legal step that closes the internal corporate process and makes the filing stage possible.

3. KRS filing after approval: 15 days to file annual accounts

Once the shareholders have approved the financial statements, the company must file the required package with the National Court Register. For a company that approves the statements on June 30, 2026, the practical filing deadline is July 15, 2026.

This stage also should not be described too vaguely. The company is not filing just one document. In practice, the filing usually includes the annual financial statements and the corporate documents showing that the statements were approved.

A typical filing package may include:

• the annual financial statements in the required electronic format,
• the shareholders’ resolutions,
• minutes or protocol of the shareholders’ meeting,
• the management report, where required,
• other documents required in the specific case.

The filing is done electronically. If the approval stage was handled incorrectly or the documentary package is incomplete, the KRS filing also becomes defective in practice.

4. CIT-8 deadline in Poland: March 31, 2026

Separate from the corporate approval process, the company must also file its annual CIT-8 corporate income tax return. For a company with a calendar tax year ending on December 31, 2025, the deadline is March 31, 2026.

This is the tax compliance side of the year-end closing. If any annual tax is due, it should also be paid by that date. In practice, the accounting closing, the financial statements and the CIT-8 preparation should be treated as one coordinated process, not as separate random tasks.

Inactive or dormant company in Poland: are financial statements still required?

This is a common misunderstanding. A company with no invoices, no sales and no business activity during the year does not automatically escape year-end obligations. An inactive sp. z o.o. still needs to prepare financial statements, approve them and file the required documents.

The fact that there were no operations usually means that the accounting package is simpler. It does not mean that the company can ignore the closing process. A separate analysis is needed only in more specific cases, for example if the activity was formally suspended for the entire relevant period and the statutory conditions for simplification are met.

Can foreign directors and shareholders handle the process remotely?

In many cases, yes. For foreign-owned companies, the year-end closing process can often be organised without travel to Poland, provided that the signature method, corporate documents and filing workflow are properly planned in advance.

The real issue is usually not whether remote handling is possible, but whether the company has a complete approval package, the right signatories and enough time to complete the process before the June and July deadlines.

Does every sp. z o.o. need a management report?

No. A Polish sp. z o.o. may be exempt if it qualifies as a micro entity or a small entity and the shareholders adopt the required resolution.

From January 1, 2025, the thresholds were increased. A company may qualify as a micro entity if in the current and previous financial year it did not exceed at least two of these three limits: PLN 2 million total assets, PLN 4 million net revenue and an average of 10 employees.

A company may qualify as a small entity if it did not exceed at least two of these three limits: PLN 33 million total assets, PLN 66 million net revenue and an average of 50 employees.

The financial thresholds alone are not enough. The shareholders should formally adopt the relevant status and required simplifications. Certain information, for example on treasury shares, may still need to be disclosed in the notes to the financial statements.

What happens if a deadline is missed?

A late filing should not be described as harmless. Missing a deadline creates unnecessary legal and tax risk for the company and for the people responsible for compliance. The right approach is to correct the issue without delay and bring the company back into proper compliance as quickly as possible.
