Changing Your Accountant in Poland: How the Handover Actually Works
Most people stay with an accountant they have stopped trusting for far longer than they should, and the reason is almost always the same: they assume the handover will be painful, and they do not know what they are entitled to ask for.
The handover is not painful. It is a defined set of files and a defined moment in the tax year. Here is both.
Your books belong to you
This is the point everyone gets wrong. An accounting office keeps your accounting records on your behalf; it does not own them. On termination you are entitled to the records back. A firm that treats your ledger as leverage in a fee dispute is not exercising a right — and any outstanding invoice is a separate matter from your entitlement to your own documents.
Ask for the handover format in writing before you have a reason to need it.
What to ask the outgoing office for
Do not accept a box of paper and a PDF. Ask for:
- The full ledger export, in a machine-readable format your new office can import, for at least the current and previous financial year.
- The chart of accounts, with any custom accounts explained.
- Fixed-asset register, with acquisition dates, values and depreciation to date. Rebuilding this from invoices is the single most tedious part of a badly handled handover.
- Open items — unpaid receivables and payables, with ages.
- Submitted filings: JPK_V7 files, CIT or PIT returns, ZUS declarations, and the confirmations of receipt.
- Payroll records — personnel files, contracts, leave balances, PIT-11s issued.
- Correspondence with the tax office, including anything open.
- Access credentials to any system registered in the company’s name.
The moment in the year that makes it easy or hard
The clean break is the end of a financial year. Closing books and opening books happen with the same figures, one office finishes and the other starts, and no period is split.
The next best is the end of a month, after the VAT filing. Straightforward, as long as it is clear in writing who files for the final month.
The one to avoid is mid-quarter with an unfiled return outstanding, because a missed filing in the gap is your liability, not theirs. If a deadline falls inside the transition, put in writing which office is filing it. Every avoidable problem we have seen in a handover comes from that sentence not existing.
Two things that have changed the calculation
Structured e-invoicing. As invoicing moves into the national system, your invoice data lives in a state system rather than only in your accountant’s software. That makes a change of office less disruptive than it used to be — but it also means both offices need to be configured correctly for the transition, and the authorisations have to move.
Structured tax reporting. Because tax authorities increasingly receive ledger-level data rather than summaries, the chart of accounts and its mapping matter more. A new office will want to review yours early. If they do not ask about it, that tells you something.
What the new office should do in the first month
A competent incoming firm will, before touching a transaction: reconcile the opening balances against the last filed accounts; check that VAT settlements and the ledger agree; review the fixed-asset register for assets that should have been written off or should not have been capitalised; and tell you plainly what it finds.
That last part matters. You are not looking for a firm that says everything is fine. You are looking for one that tells you what the previous office did and why it matters — which is also the fastest way to find out whether your instinct to leave was right.
When it is worth changing, and when it is not
Worth changing: you cannot get an answer in a language you understand; deadlines are met but only just, and only after you chase; you are told what was done but never what it means; the same reconciling item has been carried forward for a year.
Not worth changing: one bad month; a fee increase that is actually justified by growth in your document volume; a disagreement where they were right and you did not like the answer.
The good test is not whether they make mistakes. It is whether they tell you about them before you find out.
If you are considering a move, we will review your last filed accounts and tell you what we see before you commit to anything.
Frequently asked questions
- Can my accountant refuse to hand over my books if I owe them money?
- Your accounting records are yours; the office keeps them on your behalf and you are entitled to them back on termination. An unpaid invoice is a separate commercial matter to pursue on its own terms. Agree the handover format in writing at the start of the relationship, not at the end of it, and the question rarely arises.
- What should I ask my old accountant to hand over?
- A machine-readable ledger export covering at least the current and previous financial year, the chart of accounts with custom accounts explained, the fixed-asset register with acquisition values and depreciation to date, open receivables and payables, all submitted filings with their confirmations, payroll records, any open correspondence with the tax office, and access to systems registered in the company's name.
- When is the best time to change accountant in Poland?
- The end of a financial year is cleanest — one office closes the books, the next opens them on the same figures. The end of a month after the VAT filing is the next best. Avoid switching mid-period with a return outstanding, and wherever the transition falls, put in writing which office files for the final period. That single sentence prevents almost every handover problem.
- Will changing accountant trigger a tax inspection?
- No. Changing your accounting office is an ordinary commercial decision and is not itself a trigger. What can attract attention is what a change sometimes exposes — late filings, corrections, or inconsistencies carried forward — which is an argument for having a new office review the position early rather than for staying put.
- How long does a handover take?
- For a small company with clean records, days. What extends it is a missing or unreliable fixed-asset register, opening balances that do not reconcile to the last filed accounts, or a ledger delivered as PDFs rather than as data. Asking for the export format up front is what keeps it to days.
