Tax implications of owning companies in multiple jurisdictions

Expanding into international markets and building a group of companies across multiple countries is often seen as a strategic scaling move, while tax implications are treated as secondary. In practice, tax issues become the most costly surprises during due diligence or early audits. Companies face unexpected permanent establishment findings, tax residency disputes, transfer pricing adjustments, and withholding taxes on profit repatriation. The picture is further complicated by CFC rules, anti-abuse provisions, and substance requirements. Even a well-performing business can lose a significant share of profit due to structural tax mistakes. In this article, we explain the key tax risks of owning companies in multiple jurisdictions and how to structure a group without critical pitfalls.

Why does a multijurisdictional structure automatically increase tax risks?

Owning companies in multiple countries is not a problem in itself. Risks arise because tax systems overlap and interpret the same facts differently: where management is located, where value is created, and where economic activity should be taxed. As a result, even a formally compliant structure can trigger conflicting tax claims.

Key factors that almost always complicate taxation in multi-jurisdictional structures include:

• Different corporate tax residency tests (place of management, POEM, registration vs effective control);
• The risk of permanent establishment (PE) through employees, agents, or substantive functions in another country;
• Taxation of cross-border payments (dividends, interest, royalties) and withholding taxes at source;
• Transfer pricing requirements within the group;
• The application of CFC rules and anti-abuse provisions in the shareholder’s jurisdiction;
• Double taxation risks caused by poorly structured profit flows typically lead.

The combination of these factors typically leads to tax adjustments and disputes with tax authorities during growth or investor due diligence.

Tax residency and place of effective management (POEM): where business actually pays taxes

When owning companies in multiple jurisdictions, the key question is where tax authorities consider the business to “live” for tax purposes. Formal incorporation in one country does not guarantee tax residency there. In many jurisdictions, the decisive factor is the place of effective management (POEM).

POEM is assessed based on how the business actually operates: where strategic decisions are made, who controls finances, and where the management team is located. If key functions are performed from another country, that jurisdiction may treat the company as its tax resident and tax its worldwide profits.

Tax authorities look at the overall substance, not a single formal criterion. Common POEM risk triggers include:

• Management decisions effectively taken from another country;
• Board meetings and budget approvals held outside the country of incorporation;
• Concentration of key executives in one jurisdiction;
• Control over bank accounts and financial flows from a “foreign” country.

For businesses, this means that nominal structures without real substance in the country of incorporation do not protect against tax residency reclassification. At scale, these risks often surface during due diligence and can affect valuation or deal structure.

Permanent Establishment (PE): how international transactions create tax risks

When owning companies and operating across multiple jurisdictions, tax risks arise not only from group structure but also from day-to-day operations. Even without setting up a subsidiary, a business can create a permanent establishment (PE) and trigger tax liabilities in the host country.

When permanent establishment (PE) risk arises

PE is driven by actual business presence, not formal registration. Classic triggers relate to staff, offices, or activities that create a “fixed business presence” in a jurisdiction. In practice, tax authorities focus on:

• Having a team or key employees in the country;
• Using an office, coworking space, or other fixed workplace;
• Carrying out regular commercial activities locally;
• Negotiating or approving contracts through a local team.

Even remote work can create PE risk if staff perform core business functions from another country on an ongoing basis.

Dependent agents and contract conclusion

A separate risk area is the activity of dependent agents. If representatives in another jurisdiction effectively negotiate and have authority to conclude contracts, tax authorities may find PE even without a physical office. Sensitive scenarios include:

• Local teams routinely negotiating commercial terms;
• Staff effectively “selling” the product on behalf of the group;
• Contracts formally signed in one country while key decisions are made elsewhere.

For cross-border structures, this is one of the most common sources of unexpected tax presence.

PE risks in due diligence and investments

PE risks are routinely reviewed by investors and banks during due diligence. Undetected PE can lead to:

• Retroactive tax assessments and penalties;
• Urgent restructuring of operating models;
• Valuation adjustments or deal term changes.

For multi-jurisdictional groups, managing PE risk is an ongoing tax and corporate compliance task, not a one-off exercise.

Withholding tax (WHT): dividends, interest, royalties and the value of intra-group transfers

Withholding tax (WHT) is one of the most sensitive tax factors in multi-jurisdiction structures. Even with a compliant corporate setup, source withholding can materially reduce the group’s effective доход if not built into financial planning upfront. In practice, WHT often becomes a “hidden tax” that surfaces only after the structure is launched or at the first major intra-group payment.

WHT is levied in the source country on dividends, interest, and royalties paid to non-residents. This means part of the funds never reaches the recipient, even for intra-group payments. For businesses, this directly affects cash flow and can make certain financing or licensing models economically unattractive.

When double tax treaties actually help

Double tax treaties can reduce WHT rates or exempt payments, but only if substantive conditions are met. The mere existence of a treaty does not guarantee relief: banks and tax authorities assess beneficial ownership, real economic role, and business purpose within the structure.

If an intermediary is used only as a conduit to access lower rates, treaty benefits may be denied. As a result, full WHT applies, breaking the group’s financial model from the first cross-border payments.

Beneficial owner, anti-abuse tests, and denial risks

Current practice focuses on economic substance rather than formal paperwork. Anti-abuse tests (PPT/LOB), the beneficial ownership concept, and anti-treaty-shopping approaches allow authorities to deny reduced rates if a structure appears artificial.

For businesses, this means WHT relief must be “earned” through real substance, functions, and risks at the income-receiving entity. Otherwise, intra-group payments become a source of reassessments, disputes, and loss of tax predictability.

Transfer pricing and intra-group transactions: where profits are generated

When owning companies in multiple jurisdictions, tax risks often arise not from the formal group structure but from how profits are allocated between entities. Tax authorities assess whether profit allocation reflects each party’s real contribution to value creation.

Why transfer pricing matters even for small groups

Transfer pricing rules apply not only to large corporations. Startups and small cross-border groups are also scrutinised if they have intercompany services, IP licensing, financing, or function allocation.

The main risk arises when profits are concentrated in a jurisdiction with little or no real economic activity. In such cases, tax authorities may recharacterise intercompany terms and reassess taxes where value is actually created.

Intragroup services, IP, and financing as high-focus areas

Regulators pay the closest attention to intragroup services, IP arrangements, and intercompany financing. If an entity earns significant profits merely for holding IP or providing “management services” without real teams or functions, substance is questioned.

Even commercially reasonable models can be challenged if there is a mismatch between economic reality and profit allocation within the group.

Documentation and a defensible profit allocation logic

Lack of basic transfer pricing documentation often becomes an issue during tax audits and due diligence. Authorities expect not only contracts, but also a clear rationale for why profits are allocated as they are.

For businesses, this means documenting each entity’s role, functions, and risks in advance. Even minimal documentation materially reduces reassessment risk and prolonged disputes with tax authorities.

Substance and business purpose: how to prove the reality of structure

In multi-jurisdiction structures, a purely “legal shell” is no longer sufficient to secure tax or regulatory benefits. Tax authorities, banks, and investors assess whether group entities have real economic functions, business purpose, and actual control over risks and assets. A formally compliant structure without substance is increasingly viewed as aggressive tax planning and becomes vulnerable in audits.

Substance is not a vague requirement to “have an office”, but a set of indicators showing that a company genuinely operates in a jurisdiction. The focus is on where management decisions are made, where key staff are located, how functions are allocated within the group, and why a particular entity earns profits. Lack of a clear business rationale for choosing a jurisdiction or assigning a role increases the risk of denied tax benefits, anti-abuse measures, and banking issues when opening accounts.

A basic substance check usually looks at:

1. The presence of staff or directors involved in operations;
2. Actual control over key risks and assets at the entity level;
3. Access to local infrastructure (office, IT, contractors);
4. Alignment between the entity’s functions and the income it receives;
5. A clear business rationale, not purely tax-driven motives.

Even minimal but well-designed substance significantly reduces risks in tax audits, banking compliance, and due diligence. For businesses, this means deciding “where and who really manages” before launching the structure, not after regulators are already involved.

Practical checklist before launch or restructuring

Before setting up or changing a multi-jurisdictional structure, it is useful to run a short practical checklist. It helps identify common tax and regulatory risks before the structure attracts attention from banks, investors, or tax authorities. Such a preliminary self-check reduces the likelihood of costly restructuring after launch.

At a minimum, review the following areas:

• A map of jurisdictions and intra-group flows (goods, services, funds, IP);
• Potential PE/POEM triggers in countries where teams and management are based;
• Applicability of CFC rules and the reporting burden for beneficial owners;
• WHT risks on dividends, interest, and royalties, considering treaty positions;
• A basic transfer pricing model and minimum documentation set;
• Alignment of substance and corporate governance with each entity’s functions;
• A compliance plan and tax reporting calendar.

Even this concise checklist helps identify structural weak spots early and adjust the model before opening accounts, raising capital, or launching active intra-group operations.

How Key2Law helps build a tax model for an international group

When owning companies in multiple jurisdictions, tax risks rarely stem from an inherently “bad scheme”. More often, problems arise from unsynchronised decisions: a structure exists, but PE/POEM triggers are ignored, substance is not aligned, contracts do not reflect real flows, and banks or investors see inconsistencies in the economic model. In such cases, even a formally compliant setup starts to look tax- and regulatory-vulnerable.
