Moving a company to or from Luxembourg and exit tax

A company can move across a border without being liquidated and still face tax on gains that have never produced cash. For a Luxembourg departure, the decisive tax question is whether Luxembourg loses the right to tax the company’s assets. Preserving the legal entity does not answer that question. For an arrival, the starting tax values and the position in the departure country matter as much as the new registered office.

For a sponsor reorganising a holding chain, or an international entrepreneur relocating a company, the project therefore has 3 connected parts. Company law determines whether and how the entity continues. Residence rules determine which state taxes the company. Asset values determine any exit gain and the basis for future taxation.

A registered office and tax residence serve different purposes

The registered office is the seat recorded in the company’s constitutional documents. Central administration concerns the company’s actual management. Under Article 159 of the Luxembourg Income Tax Law, an ordinary company is resident for corporate income tax where its registered office or central administration is in Luxembourg.

Moving only one element can therefore leave Luxembourg residence in place under domestic law. It can also create residence in another state. The relevant tax treaty, including any applicable amendments, then needs examination. Corporate residence is not resolved by assuming that every treaty uses the same tie-breaker.

A Luxembourg office retained after management has moved abroad does not establish where decisions actually occur. Board papers, authority over investments, financing decisions and the conduct of the business provide the context. The holding company substance analysis explains why an address and genuine decision-making should be assessed separately.

Legal continuity needs a suitable cross-border procedure

The Companies Law contains a general regime for cross-border conversions and a specific regime for eligible European conversions. A conversion changes the company’s governing legal form and jurisdiction while preserving legal personality where the applicable conditions are satisfied.

The European procedure has its own scope, preparation, shareholder and creditor protections, employee provisions and legality review. A Luxembourg notary has a specific role in checking the Luxembourg part of the procedure. An ordinary international migration cannot be assigned the same process merely because the destination is geographically in Europe.

The legal work establishes the route and effective date. Contracts, bank arrangements and authorisations need examination against the proposed continuation. Tax analysis then applies to the transaction actually implemented. Neither a notarial certificate nor continuing legal personality establishes an exemption from exit tax.

A defined uncertainty about the planned migration’s Luxembourg tax treatment can make an advance tax ruling relevant to the timetable. The application concerns specified contemplated operations and does not establish their treatment in the other country.

A departure can affect the company or particular assets

Article 172 addresses a resident company transferring both its registered office and central administration abroad and consequently ceasing to be resident. The rule applies a liquidation-style tax calculation using estimated realisation values at the transfer date. This is a tax measurement, even where there is no legal liquidation.

Article 38 also covers specified transfers of assets or permanent establishment activities abroad when Luxembourg loses the corresponding taxing right. A permanent establishment is a business presence to which activities and assets are attributable for tax purposes. A Luxembourg company can remain resident while transferring an asset to a foreign permanent establishment within the scope of Article 38.

Article 38(1)(c) also addresses the company’s own departure through a transfer of its registered office and central administration. Assets that remain effectively attached to a Luxembourg permanent establishment and continue at book value are excepted from that provision.

The review consequently follows each asset, rather than stopping at the change of country on the organisation chart. An investment, a receivable, intellectual property and a business carried on through a branch may involve different taxing rights and valuation questions.

Assets genuinely retained in Luxembourg can have a different treatment

Article 172(2) permits book-value treatment for assets remaining attached to a Luxembourg permanent establishment. The attachment must reflect the retained business and the assets’ actual use. A continuing address alone cannot establish that connection.

The tax file should identify the retained activity, the allocation of assets and liabilities, and the values carried forward. An asset remaining within Luxembourg’s taxing jurisdiction differs from an asset whose future gain Luxembourg can no longer tax.

Article 38 also has a narrow exception for certain temporary transfers connected with securities financing, collateral, regulatory capital requirements or liquidity management. The assets must be intended to return within 12 months. This is not a general exemption for any cross-border transfer described as temporary.

An unrealised gain creates a financing question

The exit calculation needs a transfer-date valuation and the corresponding tax carrying amounts. A valuation used for an earlier acquisition or financing may no longer establish the amount at migration. Any exemption must be tested for the particular asset and transaction. A company labelled a holding company has no blanket exemption for everything on its balance sheet.

In a hypothetical example, an asset has a tax carrying amount of EUR 300,000 and an estimated realisation value of EUR 900,000. The EUR 600,000 difference is a potential exit gain before applicable adjustments and exemptions. It is neither the tax charge nor cash received by the company.

If the gain is taxable, the payment must be funded despite the absence of a disposal price. A projected migration balance sheet is therefore needed alongside the valuation. The corporate tax calculation also determines the effect of other income, deductions and available reliefs.

Funding the liability through a shareholder loan or account 115 contribution is a separate decision. The legal and tax classification of that funding does not determine the exit gain.

Instalments have conditions that continue after the move

Paragraph 127(2) of the General Tax Law provides, on request, equal exit tax instalments over up to 5 years without late-payment interest. The provision derives from the Law of 21 December 2018, with a further amendment in the Law of 20 December 2024.

The destination must be a European Union (EU) state or another state of the European Economic Area (EEA) with qualifying mutual assistance for recovery of tax claims. A move outside that scope does not qualify for this particular facility. The taxpayer can also waive the payment period.

The outstanding balance becomes payable if a statutory acceleration event occurs. These include disposal or withdrawal of transferred assets or activity, a further transfer to a non-qualifying destination, bankruptcy and liquidation. A qualifying transfer of a business has a specific exception where the recipient accepts the associated rights and obligations.

Failure to meet instalment obligations also ends the facility if uncorrected within a reasonable period that cannot exceed 12 months. Annual documentation that the specified disposal, withdrawal and further-transfer events have not occurred is a separate condition. Missing that documentation immediately ends the payment period and makes the outstanding balance payable. The tax debt’s limitation period is suspended during the payment period. Migration therefore leaves a Luxembourg monitoring obligation even after ordinary management has moved abroad.

An arrival needs the departure valuation and tax history

For incoming transfers, Article 35 sets the Luxembourg starting-value rules. In the situations covered by paragraph 5, assets are valued using the value established by the departure state unless that value does not reflect going-concern value. Under Article 27, going-concern value is the price that a buyer of the whole business would attribute to the asset, assuming the business continues. The acquisition date remains the actual acquisition date under paragraph 6.

This requires the departure calculation and Luxembourg opening schedule to be reconciled. The tax basis affects future depreciation and gains. A discrepancy between the states needs explanation before those figures enter later returns.

For eligible intellectual property, the earlier development and negative income also remain relevant under Article 50ter. The incoming valuation does not start a new IP exemption history.

The same discipline applies to receivables, liabilities and earlier reorganisations. Moving the company does not turn an old investment into a newly acquired one or remove the need to establish its history. Shareholder residence remains a separate matter, and future distributions require their own withholding tax analysis.

A workable migration file connects the legal effective date, actual management, taxing rights, asset values and payment obligations in both countries. That connection determines the result long after the new address has been registered.
