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

Year-end closing in Poland for a sp. z o.o. is a formal legal, accounting and tax process, not just an internal bookkeeping exercise. For a company with a calendar financial year, it requires annual financial statements, shareholders’ approval, filing with KRS and an annual CIT-8 return, each with its own deadline.

Key deadlines for the current closing cycle

For a company whose financial year runs to 31 December 2026, the main deadlines fall as follows.

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

1. Financial statements deadline: 3 months after year end

The first stage is preparing the annual financial statements. For a company with a calendar financial year, this must be done no later than 31 March of the following year, 31 March 2027 for the 2026 financial 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 remains a formal year-end reporting obligation, not just an internal accounting exercise.

2. Approval by shareholders: within 6 months of year end

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 30 June 2027 for the 2026 financial year.

In practice, this means the shareholders 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 must be properly documented. As a minimum, the approval package usually 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, the financial statements are not 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 within 15 days. For a company approving the statements on 30 June 2027, the filing deadline is 15 July 2027.

The company is not filing just one document. In practice, the filing usually includes the annual financial statements and the corporate documents showing the statements were approved:

• 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: 3 months after year end

Separate from the corporate approval process, the company must also file its annual CIT-8 corporate income tax return, by 31 March 2027 for a financial year ending 31 December 2026. 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: 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 the accounting package is simpler, not that the company can ignore the closing process. A separate analysis is needed only in more specific cases, for example if 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, year-end closing can often be organised without travel to Poland, provided the signature method, corporate documents and filing workflow are 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 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.

Since 1 January 2025, 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: 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 treated 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 compliance as quickly as possible.
