Polish Sp. z o.o. — Accounting, Tax and Annual Financial Statements
A Polish Sp. z o.o. (Spółka z ograniczoną odpowiedzialnością) is the standard private limited company registered at the KRS (Krajowy Rejestr Sądowy, National Court Register). Minimum share capital is PLN 5,000 with a PLN 50 minimum nominal share value. Every Sp. z o.o. keeps double-entry books under the Polish Accounting Act (Ustawa o rachunkowości) and the Commercial Companies Code (Kodeks spółek handlowych, KSH 2000), pays corporate income tax at 9% for small taxpayers (revenue up to €2m) or 19% standard, and files a sprawozdanie finansowe with the KRS. This page sets out what an Sp. z o.o. actually owes the tax administration (KAS) and the Social Insurance Institution (ZUS) month-to-month and year-to-year, and how our Tallinn team supports Polish entities in EN/ET/RU.
What the Polish Accounting Act (Ustawa o rachunkowości) requires
Every Sp. z o.o. keeps double-entry books, retains source documents for five years, and produces a sprawozdanie finansowe including bilans (balance sheet), rachunek zysków i strat (income statement), and informacja dodatkowa (notes). The statements are prepared in structured XML format, signed with qualified electronic signatures, approved by the shareholders’ meeting within six months of the financial year end, and filed with the KRS via the eKRS repository within 15 days of approval. Late filing triggers fines on management board members.
A VAT-registered Sp. z o.o. files monthly JPK_V7M (or quarterly JPK_V7K) via KAS (Krajowa Administracja Skarbowa), and a payroll-paying Sp. z o.o. files monthly ZUS DRA declarations and annual PIT-4R. Penalties and interest from KAS and ZUS accrue automatically — they are not a negotiating position.
Tax cycle — CIT 9% / 19%, VAT 23% and ZUS
Polish corporate income tax (CIT) is 9% for small taxpayers — gross sales revenue up to €2m in the previous tax year, or start-ups in year one — and 19% standard. Since 2022 an Estonian-style CIT (ryczałt od dochodów spółek) is also available for qualifying Sp. z o.o., deferring tax until profit distribution. VAT is 23% standard, with reduced rates of 8%, 5% and 0% for specific categories.
For Sp. z o.o. companies importing goods, running Amazon FBA, or selling SaaS across the EU we map the VAT position before onboarding — OSS, IOSS and standalone registrations each carry different cash-flow and compliance consequences. Regulated activities under KNF (Komisja Nadzoru Finansowego) — payment institutions, investment firms — add a parallel supervisory layer we handle in-house.
Sprawozdanie finansowe — filing with the KRS
The package filed with the KRS includes the bilans, rachunek zysków i strat, informacja dodatkowa, a sprawozdanie z działalności (management report) for larger entities, and — for statutorily audited Sp. z o.o. — an independent auditor’s opinion. Audit becomes mandatory once the company exceeds two of the three thresholds in two consecutive years: balance sheet EUR 2.5m, net turnover EUR 5m, 50 employees on average.
We prepare the statutory package in Polish and deliver an English management pack in parallel for foreign directors. Filing happens via the eKRS Repozytorium Dokumentów Finansowych (RDF) within 15 days of AGM approval, and the approval itself must land within six months of the financial year end.
Working with us on an Sp. z o.o.
Onboarding takes two to three weeks: scoping call, document transfer through our client portal, chart-of-accounts alignment with the Polish Accounting Act, and handover of prior working papers. We operate in English, Estonian and Russian on the same ticket; Polish-statutory filings are reviewed by a Polish-qualified accountant before submission to KAS or the KRS.
If a question is outside our core coverage — for example a complex Polish labour-code matter or a KNF licence application — we say so and introduce the right specialist rather than stretching a retainer into unpriced territory.
