The 3-6-15 schedule at a glance
Polish companies preparing annual financial statements generally follow a schedule often summarized as '3-6-15': the statement must be prepared within 3 months of the balance-sheet date, approved within 6 months of the balance-sheet date, and then filed with KRS within 15 days of approval. For a company whose financial year matches the calendar year, this means preparation by 31 March, approval by 30 June, and KRS filing within 15 days after that approval, typically by mid-July.
This schedule applies specifically to entities using full accounting books under the Accounting Act -- essentially all capital companies such as sp. z o.o., regardless of size, and any sole trader or partnership that has crossed into mandatory full-books accounting. Businesses using simplified records (KPiR or ryczałt) do not prepare statutory financial statements in this sense, which is one of the practical administrative differences between the two accounting regimes.
Year-end accounting procedures before the statement is prepared
Before the financial statement itself can be prepared, the books need to be closed for the year: all transactions for the period recorded, accruals and deferrals reviewed, and a trial balance produced that is internally consistent. This closing process should include reconciling the general ledger against subsidiary records -- bank statements, the fixed-asset register, inventory records, and accounts receivable/payable ledgers -- so that any discrepancy is caught and resolved before the statement is prepared rather than during an audit of the finished statement.
Companies with a lot of moving parts -- multiple bank accounts, significant inventory, related-party balances -- should start this reconciliation well before the formal 3-month preparation deadline, since reconciliation issues discovered close to the deadline leave little time to properly investigate and correct them.
Inventory and asset considerations where applicable
Companies holding inventory are generally required to perform a physical stocktake at or near the balance-sheet date (subject to specific timing flexibility the Accounting Act allows for some inventory types) and reconcile the physical count against the accounting records, investigating and properly recording any discrepancy rather than silently adjusting the books to match the physical count without explanation. Fixed assets should be reviewed for any impairment, disposal, or depreciation adjustment needed before the year closes.
Where a company holds assets or liabilities in foreign currency, year-end translation to PLN at the applicable exchange rate is required, and the resulting exchange differences need to be correctly recognized -- an area that is easy to get procedurally wrong if the closing process does not explicitly include a currency-revaluation step.
Preparing the financial statement itself
A full financial statement under the Accounting Act generally comprises a balance sheet, a profit-and-loss statement, explanatory notes, and -- depending on the company's size -- a statement of changes in equity and a cash-flow statement, with smaller entities benefiting from simplified reporting formats the Accounting Act permits for companies below certain size thresholds. The management board is responsible for ensuring the statement is prepared on time and signed by the persons the Act requires, typically all members of the management board and the person responsible for keeping the books.
Smaller companies should confirm which simplified reporting format they are entitled to use, since applying a larger company's full reporting format unnecessarily adds preparation work without any corresponding benefit if a simplified format is actually available to them.
Approval and filing responsibilities
Approval of the financial statement is a decision of the company's shareholders (for a sp. z o.o., typically through a shareholders' resolution at the ordinary general meeting), which must occur within 6 months of the balance-sheet date. Approval is also when the shareholders decide on the allocation of profit or coverage of loss for the year, a decision that should be documented in the resolution alongside the approval itself.
Once approved, the statement, together with the approval resolution and the profit-allocation decision, must be filed electronically with the Repository of Financial Documents linked to KRS within 15 days of approval. This filing is a distinct legal step from internal approval -- a company that approves its statement on time but misses the 15-day KRS filing window is still non-compliant, even though the harder internal step (getting shareholders to approve) has already happened.
Current deadlines and what changes them
The specific calendar dates above assume a calendar-year financial year; a company with a different financial year (sometimes chosen deliberately to separate year-end closing work from a busy operating season) needs to recalculate all three deadlines from its own balance-sheet date rather than defaulting to the calendar-year dates. In exceptional circumstances the Ministry of Finance has, in past years, extended these statutory deadlines by regulation for all or some taxpayers; companies should check for any such extension applicable to the specific year rather than assuming the standard schedule always applies unchanged.
A newly registered company's first financial year can also run longer than twelve months under specific conditions permitted by the Accounting Act, which shifts when the first set of statutory deadlines actually falls -- this is worth confirming with the accountant at incorporation rather than assuming a standard calendar-year first period.
Common errors in year-end closing
The most frequent errors are starting the reconciliation process too close to the preparation deadline, leaving no time to resolve discrepancies properly; treating the shareholders' approval step as a formality that can be left until just before the 6-month deadline, risking a late approval if a shareholder is unavailable; and missing the separate 15-day KRS filing clock that starts only once approval actually happens.
A further common error is applying the wrong reporting format -- using a full-format statement when a simplified format was available, or vice versa -- which can require redoing substantial preparation work if identified late in the process.
Planning a smooth year-end close
Build a year-end closing calendar working backward from your specific 3-6-15 deadlines: schedule reconciliation and stocktake work well ahead of the preparation deadline, schedule the shareholders' meeting with enough notice to avoid a late approval, and track the 15-day KRS filing window as its own separate deadline once approval is confirmed. Treat this as an annual planning exercise rather than something assembled reactively each year.
