Redomiciliation – the process by which a company transfers its registered seat or tax residence from one jurisdiction to another while maintaining legal continuity – triggers a cluster of tax consequences that can prove materially more significant than the corporate restructuring costs themselves. At the point of departure, most modern tax systems impose some form of exit charge on unrealised gains; at the point of arrival, the question of whether and how a step-up in asset base is recognised can determine the entity's effective tax burden for years to come. Navigating these competing demands requires careful advance planning across the relevant treaty network and a clear-eyed assessment of anti-avoidance exposure.
What Redomiciliation Actually Means for Tax Purposes
The corporate law concept of redomiciliation – retaining the same legal personality while changing the jurisdiction of registration – does not automatically map onto the tax concept of residence. Tax residence is determined by each jurisdiction according to its own domestic rules, which may look to the place of incorporation, the place of effective management and control, or both. A company that redomiciles under company law may therefore find that its previous jurisdiction of tax residence continues to treat it as resident, particularly where central management remains physically located there for a transitional period.
This mismatch between legal form and tax substance is the source of much of the complexity. Where two jurisdictions simultaneously assert tax residence, the entity may face dual taxation on worldwide income until a tiebreaker under the applicable double tax treaty resolves the conflict. Not all treaties contain an automatic tiebreaker, and the OECD's move towards case-by-case mutual agreement for dual-resident entities means that certainty can be elusive. For groups operating across multiple jurisdictions, the residual uncertainty during the transition window deserves explicit attention in any tax risk management plan.
Exit Taxation: The Departing Jurisdiction's Claim
When a company ceases to be resident in a jurisdiction – or transfers assets out of the taxing reach of that jurisdiction – the departing state typically seeks to crystallise and tax the unrealised gains embedded in those assets. The theoretical justification is straightforward: the jurisdiction has provided the economic and legal infrastructure within which value has accrued, and that claim to tax should not be extinguished simply because the taxpayer elects to leave.
Within the European Union, the framework for exit taxation is anchored in the Anti-Tax Avoidance Directive (EU) 2016/1164 (ATAD), which requires Member States to apply an exit tax on the difference between the market value of transferred assets and their value for tax purposes at the time of exit. Importantly, ATAD provides that where assets are transferred to another EU or EEA Member State, the taxpayer must have the option to defer payment of the exit tax – either in instalments over a period defined by national implementation or until a subsequent realisation event. The precise instalment period and any interest or security requirements are left to national implementation rules, which vary across Member States and remain subject to amendment.
Outside the EU, there is no common framework. Common law jurisdictions frequently impose a deemed disposal on emigration; civil law jurisdictions may impose a departure levy or a specific provision denying the deduction of future losses referable to pre-departure appreciation. Where a bilateral tax treaty is in place, it may limit the departing state's right to tax – for instance by restricting source-state taxation on capital gains – but treaty protection is not universal and is subject to the treaty's anti-abuse provisions.
One practical dimension that is often underestimated is the interaction between exit tax and transfer pricing rules. When the redomiciliation is accompanied by an intra-group transfer of intellectual property, contractual rights or a going-concern business, the departing jurisdiction will typically require that the transfer be priced at arm's length. The exit tax base and the transfer pricing base should, in principle, converge, but where they diverge – for instance because the jurisdiction applies a discounted-cash-flow methodology that differs from the group's internal pricing model – the risk of a double charge arises.
Step-Up: What the Receiving Jurisdiction Offers
The counterpart to exit taxation is the step-up: the recognition by the receiving jurisdiction of a tax base in assets that reflects their market value at the time of arrival. A full step-up means that future gains, depreciation and amortisation are calculated from the market value at entry, eliminating the risk of double taxation on pre-arrival appreciation. A partial or no step-up – still the position in a number of jurisdictions – means the receiving entity inherits a historic cost base and may face tax on gains that accrued elsewhere.
Whether a step-up is available, and to what extent, depends on national rules that are far from uniform. Some jurisdictions grant a step-up automatically on inbound migration; others require an election or a specific application; others provide a step-up only for certain asset classes and not for others. For entities arriving from a jurisdiction that has exercised its exit tax right under ATAD, the logical expectation is that the receiving Member State will recognise the stepped-up value – but the legal obligation to do so is not expressly harmonised at the EU level and depends on national implementation. This is one of several areas where open questions in the legislative architecture translate directly into financial exposure for the migrating entity.
The step-up analysis is particularly consequential for intellectual property. Where a group migrates an IP-holding entity to a jurisdiction that offers an IP Box or preferential innovation income regime, the size of the step-up determines the qualifying expenditure base for the nexus calculation and, ultimately, the proportion of IP income that qualifies for preferential treatment. Our comparative analysis of IP Box regimes across jurisdictions sets out the key design differences that affect this calculation.
Legal Continuity and Its Tax Complications
One of the distinctive features of redomiciliation – as opposed to a liquidation followed by re-incorporation – is the preservation of legal continuity: the same legal entity continues to exist, with the same contractual rights, liabilities and corporate history. From a tax standpoint, continuity is a double-edged concept. On the one hand, it avoids the deemed disposal that would typically arise on a liquidation, potentially deferring tax that would otherwise crystallise. On the other hand, continuity means that the entity carries forward its entire tax history into the new jurisdiction.
That tax history includes accumulated losses, provisions, deferred tax liabilities, thin capitalisation positions and any outstanding tax disputes. The receiving jurisdiction will generally not recognise losses incurred under the laws of another state unless its own domestic rules specifically permit cross-border loss importation – which is rare. The departing jurisdiction, conversely, may deny the carry-forward of losses once the entity ceases to be resident. The result can be that losses that were legitimately generated disappear entirely in the transition, a cost that can dwarf the structuring expenses of the redomiciliation itself.
Continuity also preserves existing contractual arrangements, including intercompany agreements. Where those agreements were priced under one jurisdiction's transfer pricing rules, the receiving jurisdiction may re-examine them on arrival and require renegotiation at arm's length under its own standards. For groups with complex intercompany structures, a redomiciliation is therefore also an occasion to review and, where necessary, refresh the entire intercompany pricing architecture.
Anti-Avoidance Exposure Under ATAD and Domestic Rules
The ATAD framework contains several provisions whose reach extends beyond the exit tax. The General Anti-Abuse Rule (GAAR) in Article 6 of ATAD requires Member States to ignore arrangements that are not genuine – meaning not put in place for valid commercial reasons reflecting economic reality – where the principal purpose or one of the principal purposes is to obtain a tax advantage that defeats the object of applicable tax law. A redomiciliation driven primarily by the desire to access a lower nominal tax rate or a preferential regime, without corresponding substance in the destination jurisdiction, is precisely the type of arrangement that the GAAR is designed to counter.
The Controlled Foreign Company (CFC) rules under ATAD are equally relevant. Following redomiciliation, if the parent company remains in a high-tax Member State and the redomiciled entity is in a lower-tax jurisdiction, the parent's jurisdiction may attribute the subsidiary's undistributed income to the parent under CFC provisions. The threshold conditions – relating to control and the effective level of taxation in the subsidiary's jurisdiction – are implemented at national level within the ATAD minimum standard, meaning the precise exposure depends on the specific Member States involved.
Hybrid mismatch rules, extended by Directive (EU) 2017/952, address arrangements that exploit differences in the tax treatment of an entity or instrument across jurisdictions. A redomiciliation that involves a hybrid entity – one that is treated as transparent in one jurisdiction and opaque in another – or that is structured alongside hybrid financial instruments can trigger the hybrid mismatch rules, potentially denying deductions or requiring income to be included where it would otherwise be sheltered. This is an area where the interaction between the departing jurisdiction's rules, the receiving jurisdiction's rules and the group's existing financing structure demands rigorous pre-transaction analysis.
Beyond the EU, many jurisdictions have adopted principal purpose tests (PPT) into their treaty network through the OECD's Multilateral Instrument (MLI). A redomiciliation that alters the group's treaty access – for instance by moving a holding company from a jurisdiction with a broad treaty network to one with a narrower network, or vice versa – may trigger treaty anti-abuse scrutiny in the jurisdictions where the group's operating subsidiaries are located. The interaction between the MLI PPT, domestic anti-avoidance rules, and the specific facts of the redomiciliation is a central element of any robust pre-transaction tax structuring exercise.

Cross-Border Implications for Groups and Holding Structures
For multinational groups, the tax consequences of redomiciliation do not stop at the borders of the departing and receiving jurisdictions. The move of a holding company or intermediate holding company affects dividend withholding tax flows, the availability of participation exemptions, the group's access to specific treaty provisions, and the consolidated tax position of the group as a whole.
Dividend flows from operating subsidiaries to a redomiciled holding company will be governed by the treaty – or, in the absence of a treaty, by domestic withholding tax rules – between the operating subsidiary's jurisdiction and the new jurisdiction of the holding company. Where the receiving jurisdiction offers a participation exemption, the conditions for that exemption (minimum holding period, minimum participation threshold, substance requirements) must be satisfied; a newly redomiciled entity may not immediately meet the holding period condition, creating a transitional gap in exemption coverage.
Interest deductibility at the level of the redomiciled entity is subject to the interest limitation rule in ATAD Article 4, which restricts the deductibility of net borrowing costs to a fixed percentage of earnings before interest, taxes, depreciation and amortisation (EBITDA), subject to national implementation variations and carry-forward provisions. Where a redomiciliation involves a refinancing or the transfer of intra-group debt, the recalibration of this limitation in the new jurisdiction is a material planning consideration.
For groups with significant intellectual property, the interaction between the redomiciliation and the group's transfer pricing documentation – particularly the master file and local file structure under the OECD's BEPS Action 13 framework – requires careful attention. The redomiciliation of an IP-holding entity changes the group's value chain, and that change should be reflected in an updated economic analysis and, where appropriate, in advance pricing arrangements with the relevant tax authorities.

The Tax Audit Risk in Redomiciliation Years
Redomiciliation years are statistically among the most audit-prone in a company's filing history. The combination of a change in residency, potential deemed disposals, intercompany transfers and treaty position changes creates a complex filing requirement in multiple jurisdictions simultaneously. Tax authorities in departing jurisdictions have a structural incentive to scrutinise the exit tax base, the valuation methodologies applied, and the substance of the departure – particularly where the move is to a jurisdiction with a lower effective tax rate.
A rigorous approach to tax audit preparedness in the redomiciliation year involves, at minimum: contemporaneous valuation reports for assets subject to exit tax; a clear and well-documented articulation of the commercial rationale for the move; evidence of genuine substance in the receiving jurisdiction (physical presence, local management, decision-making); and a coherent narrative connecting the corporate restructuring and the tax position. Where the redomiciliation is part of a broader group restructuring, the documentation should address the entire sequence of steps, not just the redomiciliation itself.
Advance clearances and rulings from the tax authorities of both the departing and receiving jurisdictions, where available, can significantly reduce the audit risk and provide certainty on the exit tax base and the step-up available in the new jurisdiction. The procedural availability and legal effect of such rulings vary considerably across jurisdictions, and the time required to obtain them must be factored into the transaction timeline.
Strategic Recommendations
Given the complexity outlined above, the following strategic considerations apply to any redomiciliation with significant tax dimensions:
- Start the tax analysis early. The tax consequences of redomiciliation are difficult to reverse once the corporate steps have been taken. A comprehensive tax analysis – covering exit tax, step-up, treaty access, anti-avoidance exposure, and the impact on the group's consolidated position – should precede any public announcement or regulatory filing.
- Align substance with structure. The single most effective defence against GAAR challenges, treaty PPT challenges and CFC exposure is genuine economic substance in the receiving jurisdiction. Substance means real people making real decisions, not merely a registered office and a letterbox.
- Coordinate the departure and arrival analysis. The exit tax base determined by the departing jurisdiction and the step-up recognised by the receiving jurisdiction should, in principle, align. In practice, they often do not. Identifying and resolving any gap in advance – ideally through coordinated rulings – avoids double taxation and the need for a costly mutual agreement procedure after the fact.
- Review the intercompany framework. Redomiciliation is the appropriate moment to review and refresh all intercompany agreements, pricing policies and financing arrangements. Existing arrangements that were appropriate in the previous jurisdiction may be inappropriate – or insufficiently documented – in the new one.
- Address the loss position explicitly. Ascertain, before completing the redomiciliation, what happens to each category of accumulated tax attribute – losses, credits, provisions – in both the departing and receiving jurisdiction. Where losses will be forfeited, consider whether there is a planning opportunity to utilise them before the move.
- Plan for the transitional period. The period between the corporate redomiciliation and the definitive resolution of tax residence is one of the highest-risk phases. Define in advance the management and governance arrangements that will apply during this period, and ensure they are consistent with the intended residency outcome in both jurisdictions.

Outlook: Regulatory Trends and Open Questions
The regulatory environment governing the tax aspects of redomiciliation continues to evolve. Within the EU, the implementation of ATAD and its successor measures has progressively tightened the conditions under which cross-border restructurings can be achieved without immediate tax cost. The OECD's Pillar Two global minimum tax rules – the subject of ongoing national implementation across OECD and G20 members as of the date these facts were verified – add a further layer of complexity, as the redomiciliation of a constituent entity within a multinational group affects the group's jurisdictional effective tax rate calculations and may trigger top-up tax obligations.
At the same time, a number of jurisdictions have actively sought to attract holding companies, IP-holding entities and regional headquarters through streamlined redomiciliation procedures and clear step-up rules. The interplay between these competitive dynamics and the anti-avoidance frameworks at EU and OECD level creates an environment in which the legal position is genuinely uncertain in a number of areas, and where the outcome of a redomiciliation can depend heavily on facts-and-circumstances analysis applied by tax authorities with different institutional perspectives.
Several open questions remain at the intersection of corporate and tax law: the precise scope of ATAD's exit tax obligation where only partial tax residence is transferred; the treatment of entities that straddle two residence tests simultaneously during a transitional period; and the extent to which domestic courts will defer to treaty tiebreaker outcomes reached through mutual agreement. These are not merely academic questions – they are live issues in tax audits and litigation across multiple jurisdictions.
