A Warsaw-based technology company was preparing to relocate its core intellectual property to a Dutch holding structure. The process looked routine – until the firm's tax team flagged that the transfer would trigger Polish exit tax on unrealised gains embedded in the IP portfolio. The exposure ran to several million zloty. No one had planned for it.
Polish exit tax applies when a taxpayer transfers assets, tax residency, or a business outside Polish tax jurisdiction, causing Poland to lose the right to tax future gains. The charge is calculated on unrealised appreciation at the date of transfer. For corporate taxpayers, the standard rate is 19 percent of the deemed gain; for individuals, rates of 19 or 3 percent apply depending on asset type. Early identification of the trigger – not the transaction closing date – is what determines whether planning remains possible.
This case study traces how the exit tax exposure arose, what strategy was adopted, and what lessons apply to any business considering a cross-border restructuring. The structure follows four stages: background, the trigger point, the planning response, and transferable lessons for owners and their advisers.
What was the background to the exit tax exposure?
The client was a Polish limited liability company operating in the software sector. Over five years it had developed proprietary algorithms qualifying for IP Box relief. The IP had been carried at historic cost on the balance sheet. Market value, however, had grown substantially. The owners planned to place the IP into a Dutch entity ahead of a planned sale to a foreign strategic buyer.
Under Polish tax law, transferring an asset from a Polish entity to a foreign entity – where Poland loses the right to tax the asset's future appreciation – constitutes a taxable event. The National Tax Administration (Krajowa Administracja Skarbowa, KAS) treats such transfers as disposals at fair market value. The difference between fair market value and the asset's tax base is the deemed gain subject to exit tax.
The company had not obtained a transfer pricing valuation before initiating the restructuring. That omission created two risks at once: an unquantified exit tax liability and potential transfer pricing exposure under Polish tax law. The KAS has 5 years to reassess transactions, so the risk was not theoretical.
- IP developed internally – low tax base, high market value
- No prior valuation commissioned
- Transfer to non-Polish entity planned within 60 days
- IP Box history created a paper trail of high-value claims
How was the exit tax trigger identified and quantified?
The trigger was identified during a pre-transaction tax review commissioned from a tax advisor Warsaw-based team. Polish tax legislation distinguishes between two categories of exit event: transfer of individual assets and transfer of tax residency. Both categories share the same core logic – Poland taxes the gain it would otherwise lose jurisdiction to tax. The review confirmed the IP transfer fell squarely within the asset-transfer category.
Quantification required an independent valuation. The firm engaged a certified valuator to assess fair market value of the IP under the income approach. The valuation produced a figure significantly above book value. At the 19 percent corporate rate, the exit tax liability exceeded PLN 3.8 million. That figure was not a penalty – it was the base tax before interest or surcharges. Had the transfer completed without disclosure, KAS could have assessed the full amount plus statutory interest running from the transfer date.
One detail proved decisive. Polish tax law allows corporate taxpayers to pay exit tax in instalments over 5 years, provided certain conditions are met and the assets move to a European Union or European Economic Area jurisdiction. The Netherlands qualifies. That option reduced immediate cash pressure significantly – from a lump-sum payment to a structured series of annual instalments. Identifying this mechanism early was the difference between a deal-stopper and a manageable cost.
We secured a restructuring outcome that preserved the instalment option for a technology client in the Mazowieckie region (winter 2026), avoiding a lump-sum exit tax demand that would have delayed the transaction by at least three months.
What planning steps reduced the exposure?
Once the liability was quantified, the planning response focused on three objectives: confirm instalment eligibility, document the transaction correctly for KAS, and sequence the restructuring to avoid triggering additional taxes. Polish tax law imposes strict documentation requirements on exit tax disclosures. A dedicated return must be filed within 7 days of the transfer event.
The strategy also addressed transfer pricing. Because the IP moved between related parties, the transaction required an arm's-length price supported by a transfer pricing study. The valuation obtained for exit tax purposes was adapted to serve as the transfer pricing benchmark. That avoided commissioning two separate reports and ensured consistency between the exit tax return and the transfer pricing documentation.
A pre-transaction restructuring review also revealed that one subsidiary held receivables that would be caught by exit tax if the parent changed residency. Those receivables were settled before the transfer, removing a secondary exposure estimated at PLN 420,000.
- Exit tax return filed within the 7-day statutory window
- Instalment schedule confirmed with KAS in advance
- Transfer pricing documentation completed before closing
- Subsidiary receivables cleared to remove secondary exposure
The family foundation structure was considered but ultimately not used here. However, for individual shareholders contemplating relocation of personal assets – including shares in operating companies – the family foundation can serve as a planning tool that defers or restructures the exit tax exposure under Polish tax law. That option is worth examining separately for owner-managed businesses.
What lessons apply to future cross-border restructurings?
The central lesson is timing. Exit tax planning must begin before the transaction structure is fixed. Once a transfer agreement is signed, the trigger date is set. Options that were available at the planning stage – including instalment payment, asset sequencing, and treaty analysis under the relevant double tax treaty framework – may no longer be accessible after the fact.
Three transferable lessons stand out for any business owner or in-house team preparing a cross-border move. First, any asset with embedded unrealised gain is a potential exit tax trigger – IP, shares, real estate, and receivables all qualify. Second, the destination jurisdiction matters: EU and EEA transfers preserve the instalment option; transfers to third countries do not. Third, KSeF Poland obligations and other compliance requirements do not pause during a restructuring, so the administrative burden runs in parallel.
Our team obtained a confirmed instalment schedule and a clean KAS acknowledgment for a manufacturing group relocating IP assets to Luxembourg from Silesia (spring 2026), preserving deal timing and avoiding an unplanned cash outflow exceeding PLN 5 million.
The self-assessment checkpoint is straightforward. If your company holds assets worth materially more than their tax base, and any cross-border transfer is under consideration, the exit tax analysis should be the first item on the tax adviser's agenda – not the last.
What to prepare before a cross-border restructuring:
- Asset register with current market values and tax bases
- Identification of all assets with unrealised gains above PLN 4 million threshold
- Confirmation of destination jurisdiction (EU/EEA or third country)
- Transfer pricing documentation for related-party transfers
- Timeline confirming 7-day filing window can be met
Specific circumstances vary. An exit tax exposure that is manageable with six months of planning can become a transaction-blocking liability identified three weeks before closing. That gap – between early advice and late discovery – is where value is lost and deals collapse.

Frequently asked questions
Q: At what asset value does Polish exit tax become mandatory?
A: For corporate taxpayers, exit tax applies when the total market value of transferred assets exceeds PLN 4 million. For individuals, the threshold is PLN 4 million as well, but calculated across all assets subject to the charge. Assets below this threshold are not subject to the tax, though the calculation must still be performed to confirm eligibility for the exemption.
Q: Is it possible to avoid exit tax entirely by restructuring within Poland?
A: A common misconception is that keeping the transaction within Poland automatically avoids exit tax. The trigger is loss of Polish taxing jurisdiction over future gains – not the nationality of the parties. A Polish company transferring assets to a Polish branch of a foreign entity can still trigger the charge if the asset's economic connection to Polish tax jurisdiction is severed. Each structure must be analysed individually.
Q: How long does the instalment payment option last, and what happens if conditions are breached?
A: The instalment option allows payment over up to 5 years in equal annual amounts. If the asset is subsequently sold, transferred outside the EU or EEA, or the company loses its EU or EEA status, the remaining instalments become immediately due. Interest accrues from the original transfer date, not from the date the condition is breached. Early legal advice on maintaining instalment eligibility is therefore essential throughout the holding period.
