Do You Legally Need an Accountant for a Polish Company?

In short:

• No Polish law says you must hire an accountant. What the law says is that your company must keep proper accounting records — and that the duty belongs to the management board, not to whoever does the data entry.
• An sp. z o.o. keeps full accounting from day one, in Polish and in złoty, under the Accounting Act of 29 September 1994 — however small it is, and even if it has not traded yet.
• Commercial bookkeeping was deregulated on 10 August 2014. No state certificate is required to keep books for a client, but a service provider must carry professional liability (OC) insurance.
• You can delegate the work. You cannot delegate the responsibility — except deliberately, in writing, and never for the stocktake.
• From 1 April 2026 nearly every company must issue invoices through KSeF, Poland’s national e-invoicing system. That raises the practical bar again.

Is an accountant legally required for a Polish company?

No. Nothing in Polish law obliges a company to sign a contract with an accounting office or to employ a qualified accountant. What the Accounting Act obliges you to do is keep the books — correctly, in Polish, in Polish złoty, and on time.

That distinction is where most foreign founders misjudge the risk. Nobody at the tax office checks whether you have an accountant. They check whether your JPK_V7M arrived, whether your CIT-8 was filed by the end of the third month after year-end, and whether your annual financial statement reached the KRS. If those things happen on time and correctly, no authority asks who did them.

So the real question is not “am I required to hire someone?” It is “can I produce all of that myself, in Polish, every month, without errors?”

Who is legally responsible if the books are wrong?

The management board. Under Article 4(5) of the Accounting Act the kierownik jednostki — for an sp. z o.o., that is the board — is responsible for performing the accounting duties. Engaging an accounting office does not move that responsibility by default.

It can be moved, in part, but only on purpose. The Act allows accounting duties to be entrusted to a business that keeps books as a service, and that business then becomes liable for damage caused while performing them — provided it accepts that liability in writing. One duty never transfers under any arrangement: responsibility for the stocktake (inwentaryzacja) stays with the company’s management.

In practice this makes your engagement letter worth reading closely. “We will do your bookkeeping” and “we accept liability under Article 4(5) of the Accounting Act” are not the same sentence, and only one of them changes who pays when something goes wrong.

What	Who it binds	Can it be delegated?
Keeping the accounting records	The board (kierownik jednostki)	Yes — to a bookkeeping business
Liability for damage from those duties	The board by default	Only if the provider accepts it in writing
The annual stocktake (inwentaryzacja)	The board	No — never transfers
Signing and filing the financial statement	The board	No — board members sign it themselves
Tax settlements and returns	The taxpayer (the company)	Work yes, taxpayer status no

Can I do my own bookkeeping for an sp. z o.o.?

Legally yes. Practically it is a poor trade for almost every foreign founder, because an sp. z o.o. never gets the simplified option — it keeps full double-entry books from its first day, with a chart of accounts, a general ledger, subsidiary ledgers and an annual financial statement.

Three things usually decide it:

• Language. The books are kept in Polish, filings are in Polish, and correspondence from the tax office and the KRS arrives in Polish with short deadlines attached.
• Volume of filings. A typical trading company files JPK_V7M every month, runs payroll and ZUS if it employs anyone, files CIT-8 annually and prepares a financial statement — none of it optional, all of it dated.
• Cost of being wrong. A late JPK, a mis-set VAT rate or a missed KRS filing costs far more than the bookkeeping it was meant to save, and the liability lands on the board personally.

If you read Polish, your company is dormant or near-dormant, and you enjoy administrative work, doing it yourself is defensible. Otherwise it is a false economy. See full accounting or simplified bookkeeping for which regime actually applies to your legal form.

What qualifications must a Polish accountant have?

Since 10 August 2014, when the Act of 9 May 2014 on facilitating access to certain regulated professions came into force, keeping books commercially has not been a licensed activity. There is no state accounting certificate to check.

What a provider must have is narrower and easier to verify: full legal capacity, no conviction for offences against the credibility of documents, property, business dealings, or money and securities, no fiscal-offence conviction, no conviction under Chapter 9 of the Accounting Act — and mandatory OC (civil liability) insurance for the bookkeeping activity.

Two adjacent professions did stay regulated, and the difference matters when you are buying:

• Doradca podatkowy (tax adviser) — a licensed profession with a state exam and a professional register. Tax advisers may represent you before the tax authorities and give binding tax opinions.
• Biegły rewident (statutory auditor) — licensed; only an auditor may audit a financial statement where an audit is required.

A competent accounting office will tell you plainly which of these it holds and where it brings in a licensed specialist.

What does a Polish accounting office actually do each month?

The recurring work is more mechanical than most founders expect, and it is the rhythm — not the complexity — that catches people out.

Recurring obligation	Typical cadence	Deadline pattern
JPK_V7M (VAT records and return)	Monthly	25th of the following month
VAT payment	Monthly	25th of the following month
ZUS contributions and returns	Monthly, if you employ	20th of the following month
PIT advances for employees	Monthly, if you employ	20th of the following month
CIT advances	Monthly or quarterly	20th of the following period
CIT-8 annual return	Annually	End of the 3rd month after year-end
Financial statement	Annually	Prepared within 3 months of year-end

Alongside that sits the work you actually notice: classifying costs correctly, keeping the VAT deduction defensible, watching the limits that change your regime, and answering the tax office when it asks.

What changes in 2026 — KSeF and e-invoicing?

KSeF (Krajowy System e-Faktur) becomes mandatory in stages. From 1 February 2026 it applies to businesses whose 2025 sales including VAT exceeded PLN 200 million. From 1 April 2026 it applies to everyone else — which means essentially every foreign-owned company reading this.

There are two easements worth knowing. Micro-businesses whose invoiced sales stay at or below PLN 10,000 gross in a given month may keep issuing outside the system until 31 December 2026 and join on 1 January 2027. And sanctions for breaching the KSeF obligations are suspended from 1 February to 31 December 2026 — a grace period, not an exemption.

The practical effect is that invoicing stops being a document you email and becomes a transaction with a government system. For a founder who was managing on spreadsheets, 2026 is the year that stops working.

What happens if the books are wrong or filed late?

The consequences are layered, and they escalate from money to personal liability:

• Late or missing tax filings attract interest and fiscal-penal liability under the Fiscal Penal Code, assessed against the person responsible.
• Not keeping books, or keeping them unreliably, is an offence under Chapter 9 of the Accounting Act — punishable by a fine or restriction of liberty.
• A missing financial statement at the KRS triggers coercive proceedings, fines on board members, and in extreme cases dissolution of the company. Annual financial statement deadlines sets out the full 2026 calendar.
• Board liability under Article 299 of the Commercial Companies Code can reach board members’ personal assets where a company’s debts cannot be recovered.

None of these depend on intent. “My accountant did not tell me” is not a defence that moves the duty.

How do you choose an accountant as a foreign founder?

Ask questions that separate a bookkeeper from an adviser:

• Do you accept liability under Article 4(5) in writing, and what is your OC cover?
• Who will I actually speak to, and in what language? A Polish-only relationship works until the first tax-office letter.
• Are you ready for KSeF, and what do I have to change before 1 April 2026?
• Will you tell me when a limit is about to change my regime — full books, small taxpayer status, VAT — or only report it afterwards?
• What is not included in the monthly fee? Annual statements, audits and correspondence with authorities are often priced separately.

For a foreign-owned company, the language question is not a comfort issue. It decides whether you understand your own numbers well enough to make decisions from them.

What does accounting cost in Poland?

There is no honest single figure, and any office that quotes one before seeing your business is guessing. Price is set by the work, and the work is driven by:

• Legal form — full books for an sp. z o.o. cost more to keep than a sole trader’s simplified records.
• Document volume — invoices in and out per month is the single biggest driver.
• VAT status and transaction types — domestic only is simpler than EU acquisitions, exports or reverse charge.
• Payroll — headcount, contract types and foreign employees each add work.
• Foreign-currency and cross-border flows — valuation, transfer pricing and treaty questions.
