Economic Substance in 2026: What International Businesses Actually Need

The Substance Debate Has Changed

For several years, the phrase “economic substance” became closely associated with a particular generation of legislation introduced in a number of international financial centres. That history has created confusion. Some international business owners now assume: “If the jurisdiction has repealed its Economic Substance Regulations, substance no longer matters.” That conclusion is unsafe.

The standalone reporting regime may disappear. The underlying international tax and regulatory environment does not. The OECD/G20 Base Erosion and Profit Shifting programme addresses a range of international tax issues, including transfer-pricing outcomes, treaty abuse and other arrangements in which the allocation of taxable profits may not correspond with the relevant economic activity or applicable tax rules. Transfer pricing examines functions, assets and risks. Treaty anti-abuse rules examine the purpose and commercial reality of structures. Corporate residence rules can examine where management actually occurs. Banks examine where customers genuinely operate. Regulators examine whether licensed businesses possess the people and infrastructure required to perform their functions.

The modern substance question is: does the legal, tax and operational structure correspond with what the business actually does?

What Does Economic Substance Actually Mean?

There is no universal substance checklist applicable to every international company. At its broadest, economic substance concerns the degree to which the legal structure corresponds with genuine activities, functions, people, management, assets, risks and commercial purpose.

Depending upon the particular rules being considered, relevant factors can include: directors, senior management, employees, premises, operating expenditure, decision-making, income-generating activities, assets, intellectual property, contracts, risk management, accounting records, banking arrangements and commercial rationale.

But those factors cannot sensibly be applied identically to every company. A software business employing 70 developers should not look like a passive holding company owning shares in three subsidiaries. A trading company should not necessarily look like a consultancy. A regional headquarters should not look like an intellectual-property company.

Substance should be proportionate to function.

Start With What the Company Actually Does

Consider five companies:

• Company A — Holding Company: Its principal purpose is to own shares in operating subsidiaries, exercise shareholder rights, receive dividends and make investment decisions.
• Company B — International Trading Company: It purchases goods from suppliers, negotiates contracts, manages logistics and sells to customers internationally.
• Company C — Consultancy: Its revenue is generated principally through the knowledge, expertise and work of consultants.
• Company D — Intellectual-Property Company: It owns valuable IP and derives income from its development, licensing or exploitation.
• Company E — Regional Headquarters: It manages regional operations and performs strategic, financial, administrative or executive functions for a group.

It would make little commercial sense to require identical employees, premises, expenditure, directors, assets and infrastructure from all five. The appropriate substance should follow what each company actually does.

A Registered Office Is Not an Operating Business

Almost every incorporated company requires a registered office or registered address. That address performs legitimate and important functions. It may be used for statutory correspondence, service of legal documents, corporate records, regulator communications and company administration. But a registered office does not necessarily establish that the company's commercial activities are performed there.

There is nothing inherently wrong with this. A genuine holding company may operate perfectly legitimately from professional corporate premises. A small consultancy may use serviced offices. A remote technology business may require relatively little conventional office space.

The difficulty begins when the address is presented as evidence of activity that does not actually occur there. Imagine a company claiming to conduct a substantial international trading operation from Country A — yet in Country A no employees work, no executives operate, no contracts are negotiated, no commercial decisions are made, no customers are managed, no suppliers are managed, and the directors barely understand the business.

The problem is not the address. The problem is the difference between the claimed function and the actual function.

Substance Is Not the Same as Tax Residence

This distinction is essential. Corporate tax residence asks, broadly: which jurisdiction regards this company as resident for tax purposes? Economic substance asks different questions: what activity actually occurs? Who performs it? Where does it occur?

The two concepts can overlap because both may involve directors, management, decision-making, employees, premises and activities. But they are not interchangeable. A company might satisfy a jurisdiction's domestic residence test while possessing relatively little operational substance. Conversely, a company might conduct substantial activity in a country without being incorporated or necessarily tax resident there.

The Complete Analysis

The complete analysis can therefore involve several separate questions:

• Where is the company incorporated?
• Where is it tax resident?
• Where is it actually managed?
• Where are its income-generating activities performed?
• Where are its employees?
• Where are its assets?
• Where are economically significant risks controlled?
• Does it have a permanent establishment elsewhere?

Those answers should form a coherent picture.

Tax residence and economic substance can overlap. They are not interchangeable.

The UAE: What Changed After the ESR Regime?

The UAE introduced standalone Economic Substance Regulations in 2019. The regime applied to specified Relevant Activities and imposed notification, reporting and substance requirements upon affected businesses. Then the regulatory architecture changed.

Following implementation of the federal Corporate Tax regime, Cabinet Decision No. 98 of 2024 cancelled economic-substance notification and reporting requirements for financial years ending after 31 December 2022. The UAE Ministry of Finance confirmed that companies no longer need to submit ESR notifications or reports for financial years ending after that date. Obligations relating to earlier periods can nevertheless remain relevant.

It would be tempting to summarise that development as: “The UAE abolished substance requirements.” That would be misleading. The accurate conclusion is: the UAE cancelled its standalone ESR reporting regime prospectively, while substance continues to matter through the wider Corporate Tax and commercial framework.

The UAE did not “abolish the idea of substance.” The standalone ESR reporting architecture changed. Current Corporate Tax and Free Zone rules must be analysed on their own terms.

UAE Free Zones: 0% Is Not Automatic

This is particularly important for UAE Free Zone companies. A Free Zone licence does not automatically mean 0% Corporate Tax on everything. The UAE Corporate Tax regime permits a Qualifying Free Zone Person to benefit from a 0% rate on Qualifying Income, subject to the statutory conditions.

One of those conditions is explicit: maintain adequate substance.

The applicable UAE rules require a Qualifying Free Zone Person to undertake its core income-generating activities in a Free Zone and, having regard to the activities performed, maintain:

• adequate assets;
• an adequate number of qualified employees; and
• adequate operating expenditure.

The regime can permit outsourcing in prescribed circumstances, provided appropriate supervision is maintained. The FTA also confirms that Qualifying Free Zone Person status requires adequate substance, Qualifying Income, transfer-pricing compliance and satisfaction of the other statutory conditions.

Free Zone does not mean “no substance.” 0% is not an automatic rate on everything.

Holding Companies and Proportionality

Holding companies often create unnecessary confusion because genuine holding activity may require relatively little physical infrastructure. Imagine a company whose principal function is to own shares in three subsidiaries. It does not manufacture, sell products, run a warehouse, employ salespeople or develop technology. Requiring it to maintain 20 employees and a large operating office merely to look substantial would itself be artificial.

But that does not mean nothing matters. Depending upon the structure and applicable rules, a genuine holding company may still need appropriate: corporate records, ownership records, directors, board oversight, investment decisions, accounting, banking, shareholder decisions and governance. Its substance should correspond with its holding function.

A holding company should look like a holding company. Not a fictional regional headquarters.

The principle is proportionality.

Trading Companies and Commercial Functions

Now consider an international trading business claiming substantial profit from purchasing, pricing, negotiating, selling and managing international supply relationships. Relevant questions might include:

• Who negotiates with suppliers?
• Who determines purchasing strategy?
• Who sets prices?
• Who negotiates customer contracts?
• Who controls inventory risk?
• Who manages credit risk?
• Who manages logistics?
• Where do those people work?
• Where are the significant commercial decisions made?

If all of those functions occur in Country A while most profit is attributed to a lightly staffed company in Country B, the structure may require careful transfer-pricing and tax analysis. The issue is not: “Does Country B have an office?” It is: “What economically significant function does the Country B company perform?”

What economically significant function does this company perform?

Consultancies: People Are the Business

For many consultancy and professional-services companies, the principal economic asset is people. If a consultancy generates £5 million annually because ten highly experienced professionals advise clients, the location and employment of those professionals can be highly relevant.

Ask:

• Who wins the clients?
• Who performs the engagements?
• Who owns the client relationships?
• Who determines fees?
• Who supervises the work?
• Who bears professional risk?
• Where are the consultants located?

A consultancy with one administrator in Jurisdiction A and all consultants, clients and management in Jurisdiction B may need a particularly good explanation for substantial profits attributed to Jurisdiction A.

Function first.

Intellectual Property, DEMPE and Value Creation

Intellectual-property structures are among the clearest examples of why legal ownership alone does not determine every transfer-pricing outcome associated with intangible value. It may be legally possible to transfer patents, software, trademarks, copyright, technology rights or licensing rights to a company in another jurisdiction. But transfer-pricing analysis asks deeper questions.

OECD guidance on intangibles examines the functions associated with:

Development · Enhancement · Maintenance · Protection · Exploitation

— commonly abbreviated as DEMPE.

Relevant questions can therefore include:

• Who developed the IP?
• Who funds continued development?
• Who employs the developers or researchers?
• Who decides the R&D programme?
• Who controls development expenditure?
• Who decides licensing strategy?
• Who protects the IP legally?
• Who commercialises it?
• Who controls the relevant risks?

Legal ownership remains important. But: legal ownership alone does not answer every transfer-pricing question.

People Matter — But Headcount Is Not the Test

Employees can be among the strongest indicators of where an active company's economic functions are performed. But simply counting employees is crude. Ten administrators do not necessarily perform the same economic function as three senior investment professionals. The useful questions are: What do these people actually do? Are they qualified to perform those functions? Do their functions correspond with the company's income? Who makes significant decisions? Who controls material risks? Where do those people work?

Premises Should Make Commercial Sense

A digital consultancy may genuinely require little more than flexible workspace, meeting facilities and remote-working infrastructure. A distribution company may require warehouse facilities and logistics infrastructure. A regulated financial-services company may need premises consistent with its licensing obligations. A regional headquarters might require executive offices, meeting rooms, finance staff and administrative infrastructure. The strongest evidence is not necessarily the most expensive office. A modest office genuinely occupied by the people operating the business can be considerably more meaningful than an impressive suite nobody uses.

Directors Must Do More Than Lend Their Names

Professional and resident directors can perform legitimate and valuable roles. They can provide governance, local expertise, independent judgement, regulatory experience and commercial oversight. But genuine directorship involves more than signing documents. Ask:

• Does the director understand the company?
• Do they receive appropriate information?
• Do they participate in strategic decisions?
• Can they challenge proposals?
• Do they possess real legal authority?
• Can they refuse a transaction?
• Do they exercise independent judgement?
• Are board decisions actually taken by the board?

A director who automatically approves whatever a foreign owner has already decided may provide very different substance from a director who genuinely participates in running the company.

The strongest board minutes are the ones recording what competent directors actually did.

Outsourcing Does Not Automatically Destroy Substance

Modern businesses outsource extensively — accounting, payroll, compliance, IT, company secretarial work, logistics, administration, customer support and specialist professional services. Outsourcing is not inherently inconsistent with genuine substance. Even the UAE Free Zone rules expressly contemplate outsourcing of certain activities where the statutory conditions, including appropriate supervision, are satisfied. The more useful questions are: What has been outsourced? Who performs it? Where? Who controls it? Who supervises it? Who makes the significant decisions?

Outsourcing a function is very different from outsourcing the entire economic reality of the company while retaining only the legal shell.

Banking and the “Why Here?” Test

Economic substance is not solely a tax-authority issue. Financial institutions conduct their own risk assessment. A bank examining an international company may ask: Why is it incorporated there? Where does it actually operate? Where are the directors? Where are the shareholders? Where are employees located? Where are customers? Where are suppliers? Where are contracts performed? What transactions are expected? Why does the company need this particular banking relationship?

These questions overlap with tax substance. But the bank is assessing different risks: AML/CFT, sanctions, fraud, geography, transaction risk and commercial plausibility. This explains why a structure can be perfectly valid under company law yet difficult to bank.

Commercial coherence matters.

One of the most powerful questions in international structuring is extraordinarily simple: why is this company here? Good answers might include: access to a regional market, proximity to customers, specialist employees, regulation, investor requirements, legal infrastructure, logistics, capital markets, financial infrastructure, group headquarters, R&D, intellectual-property ecosystem, political stability or management location. Tax efficiency can legitimately form part of the answer. But where the entire answer is “because the tax rate is lower,” the structure may deserve more careful analysis.

Substance and Transfer Pricing

Substance becomes particularly important within multinational groups. Suppose Company A receives a large proportion of group profits. The obvious question is: what does Company A actually do to earn them?

OECD transfer-pricing guidance applies the arm's-length principle to transactions between associated enterprises and analyses economically significant functions performed, assets used and risks assumed. This means legal agreements matter. But they do not exist in isolation. If the contract says Company A controls a major commercial risk while all meaningful decisions concerning that risk are actually made by executives of Company B, the factual position requires analysis.

Similarly, where valuable IP is legally owned by Company A but the economically significant development and exploitation functions occur elsewhere, the appropriate profit allocation may not be determined simply by the registration certificate.

Substance and transfer pricing are often two parts of the same commercial story.

Substance and Treaty Access

Double taxation agreements can provide valuable protection and, depending upon the treaty, reduced taxation of cross-border dividends, interest and royalties. But modern treaty policy increasingly seeks to prevent treaty shopping. The OECD/G20 BEPS programme introduced minimum standards addressing treaty abuse. Many modern treaties now contain anti-abuse provisions including a Principal Purpose Test.

The broad principle is that treaty benefits can potentially be denied where obtaining the benefit was one of the principal purposes of an arrangement or transaction, unless granting the benefit would accord with the object and purpose of the relevant treaty provisions. Not every treaty contains a Principal Purpose Test. The wording of the particular treaty must be checked.

This means an international group should not ask only: “Which country has the best treaty with Country X?” It should also ask: “Why would this company genuinely belong in that jurisdiction?” Treaty access should complement commercial structure. It should not substitute for it.

Read the actual treaty.

Global Minimum Tax: Why Pillar Two Matters at the Top End

For the largest multinational groups, the landscape has changed further through OECD Pillar Two. The Global Anti-Base Erosion (GloBE) framework is designed around an effective minimum level of taxation of 15% for large multinational groups within scope. The principal consolidated revenue threshold is €750 million, subject to the detailed rules, exclusions and implementation in relevant jurisdictions.

Businesses below the applicable consolidated-revenue threshold will generally fall outside the GloBE rules, subject to the detailed scope provisions, exclusions and jurisdiction-specific implementation. But its broader significance should not be ignored. International tax competition is increasingly moving away from a simple question — where can profits be booked at the lowest headline rate? — towards a much more sophisticated analysis involving where functions occur, where value is created, where people work, where risks are controlled and where income is taxed.

Pillar Two does not itself create a universal economic-substance test. But it reinforces the broader direction of international tax policy: structures should correspond with commercial reality.

Appropriate Substance, Not Artificial Substance

There is an opposite mistake. Some businesses become so concerned about substance that they create infrastructure they do not genuinely need. They may be encouraged to obtain large offices, unnecessary employees, multiple directors and expensive administration simply to create the appearance of weight. That can make a structure more expensive without necessarily making it stronger.

A passive holding company should not pretend to be a regional headquarters. A one-person consultancy should not manufacture a fictional workforce. A genuine remote business should not automatically require a conventional office simply because traditional businesses once did.

The objective is not maximum substance. It is appropriate substance.

A small holding company can legitimately say: “We are a holding company. We require limited operational infrastructure.” A start-up can legitimately say: “We are newly established and currently have two employees.” A remote consultancy can legitimately say: “Our consultants work remotely and we use serviced meeting facilities when required.” Those facts may be entirely defensible. Trying to disguise them through activity that does not reflect the actual business, nominal employment, unused offices or directors who do not genuinely perform the role can create much more serious questions.

The Danger of Substance Packages

International corporate providers sometimes market substance as though it were a product. A typical package might include: registered office, local telephone, dedicated desk, resident director, mail handling and quarterly board meeting. Every one of those services can be entirely legitimate.

The problem arises when the package is presented as though purchasing the services automatically establishes the economic substance required for every business. It does not.

• A desk does not employ people.
• A telephone number does not negotiate contracts.
• A board meeting does not relocate decisions already made elsewhere.
• A resident director does not create genuine management if they possess no meaningful authority.

Substance cannot be purchased as decoration. Artificial substance can be worse than limited substance honestly explained.

Building a Coherent International Group

Substance analysis should not always stop with the individual company. Consider a hypothetical group structure:

• UK Parent Company — group ownership, board oversight and parent-company functions.
• UAE Regional Company — Middle East management and regional commercial operations.
• Singapore Trading Company — Asian trading and commercial management.
• Hong Kong Procurement Company — Asian sourcing and procurement.

Each entity should have an intelligible function. That can create a coherent international operating model.

But imagine instead that every important employee works in Britain, every major decision is made in Britain, every customer relationship is controlled from Britain, every commercial risk is managed in Britain — while most profits accumulate in lightly staffed entities elsewhere. That arrangement may require much more careful analysis.

Who does what, where, and why?

This is an illustration, not a recommended structure. The appropriate group architecture depends upon the actual business, its activities, its people and the applicable tax and regulatory framework.

The International Structure Should Tell One Story

The strongest international structures increasingly have one characteristic in common: coherence. The incorporation, tax residence, management, employees, premises, contracts, banking, transfer pricing, profit allocation and commercial rationale do not need to exist in one country. International business would cease to be international if they did. But the relationship between them should make sense.

The Coutts Six-Part Substance Framework

This is a Coutts planning framework. It is not a universal statutory test. If all six elements tell the same commercial story, the structure becomes substantially easier to explain.

1. Purpose: Why does the entity exist? What commercial function does it perform within the business or group?
2. People: Who performs that function? Where are they located? What skills and authority do they possess?
3. Decisions: Who makes the important decisions? Where are those decisions genuinely made?
4. Premises & Assets: What infrastructure does the activity genuinely require? Where is it located?
5. Expenditure: Does the company's expenditure correspond with the scale and nature of the activities attributed to it?
6. Evidence: Can the company demonstrate the above through genuine contracts, payroll, invoices, board records, accounts, leases, employment agreements, bank records and operational documentation?

If all six elements tell the same commercial story, the structure is easier to explain.

Ten Common Substance Errors

1. Confusing a registered office with an operating office. They perform different functions.
2. Assuming repeal of an ESR regime means substance no longer matters. The UAE demonstrates why this is incorrect.
3. Using nominal directors. The role should be genuine.
4. Creating artificial employees. Employees should perform real functions.
5. Renting premises nobody uses. Infrastructure should correspond with the activity.
6. Ignoring where the founder actually works. Owner-managed businesses require particular care.
7. Separating profits from functions. Transfer-pricing rules can examine functions, assets, risks and value creation.
8. Assuming every company requires the same substance. A holding company and an operating business are fundamentally different.
9. Treating substance as an annual compliance exercise. Commercial substance exists — or does not exist — throughout the year.
10. Designing substance after incorporation. It should influence the jurisdiction and operating model from the beginning.

Fifteen Questions Before Establishing an International Company

1. What will this company actually do?
2. Why should that function be located in this jurisdiction?
3. Who performs its core functions?
4. Where will those people work?
5. Who makes strategic decisions?
6. Where will those decisions be made?
7. What premises does the activity genuinely require?
8. What assets will the company use?
9. What operating expenditure should reasonably arise?
10. Does the proposed profit allocation correspond with the functions performed, assets used and risks controlled?
11. What corporate tax residence rules apply?
12. Could activities create a permanent establishment elsewhere?
13. Are there specific statutory, regulatory or tax substance requirements?
14. Will treaty benefits or preferential tax treatment be sought?
15. Can the entire structure be explained coherently to a tax authority, regulator, investor or bank?

If the answer to question 15 is no, the structure deserves further work.
