AI agents can now perform work that once required people: preparing analysis, interacting with software, generating documents, monitoring systems and executing predefined actions.
That creates a genuine international-tax question.
If more of a company’s activity is performed by software, where is the company managed and where does it carry on business?
Current tax rules do not provide a general answer that says “the AI agent creates a permanent establishment” or “the server determines company residence”.
The safer conclusion is the opposite: AI increases the importance of identifying the human and factual reality behind the automation.
Key takeaways
- Company residence, effective management and permanent establishment are separate concepts. AI does not collapse them into one technology test.
- Current official guidance still focuses on legally attributable management, people, places and business functions. An AI agent is generally part of the operating system of the enterprise, not a new treaty-residence category.
- Governance evidence becomes more important as automation grows. Delegation, approvals, authority and decision logs may be needed to show who actually controls the business and where.
Facts: the law still looks for management and nexus
The United Kingdom provides a clear example of a management-based residence test.
HMRC states that a company incorporated outside the UK can be UK resident if the central management and control of its business is exercised in the UK. The test is factual and asks where the highest-level management and control actually abides.
The UAE uses different statutory language but asks a related factual question.
The Federal Tax Authority states that a foreign-incorporated juridical person can be a UAE resident where it is effectively managed and controlled in the UAE. One key factor is where strategic and policy decisions necessary for the conduct of the business are regularly and predominantly made.
Permanent establishment is a different issue.
The OECD’s 2025 update to the Model Tax Convention added guidance on cross-border remote work, including when a home office can create a taxable business presence. That guidance is about factual business presence and human remote work. It does not create a rule under which software itself automatically becomes a PE.
Interpretation: automation does not abolish attribution
A company acts through systems, employees, officers, directors and authorised persons.
Software can increasingly perform an action, but tax law still needs to attribute that action to the enterprise and decide which facts are legally relevant.
That means the useful question is not “where is the AI?”
It is:
who set the policy, who granted the authority, who can override the system, where are strategic decisions made, and what business activity is actually carried on in each jurisdiction?
An agent may execute a transaction automatically.
The decision to deploy the agent, define its permissions, set risk limits and approve exceptions may remain a human management function.
The mechanism
AI can create international-tax friction through concentration of control.
A small founder-led company may automate customer service, research, billing and operational workflows. If one founder in one country sets the strategy, approves major commitments and controls the systems, automation can make the founder’s location more — not less — important.
A different company may have distributed directors, real local management teams and tightly limited automated systems. The same software would then sit inside a very different residence analysis.
For PE, the mechanism is also factual.
A home office, employee, dependent agent or other business presence can create nexus under applicable domestic law and treaty rules. Automating part of that activity does not by itself answer whether the threshold is met.
Two concrete jurisdictional lenses
A foreign company controlled from the UK
A non-UK company whose real strategic decisions are consistently made by a founder or board in the UK can raise UK company-residence questions under the central-management-and-control test.
The fact that many operational decisions are executed automatically does not necessarily weaken that connection.
It may make it easier to identify where the remaining high-level decisions are concentrated.
A foreign company controlled from the UAE
A foreign-incorporated company whose key management and commercial decisions on strategic and policy matters are regularly and predominantly made in the UAE can raise UAE residence questions.
The FTA also recognises that dual-residence situations may need to be resolved under an applicable double-tax treaty.
Again, the relevant inquiry is management in substance, not merely where a cloud server happens to be located.
The strongest countercase
AI capability is advancing faster than tax guidance.
Future systems may negotiate, contract, allocate resources or execute business strategy with materially less human intervention than today’s tools.
At some point, existing concepts may be tested by facts their designers did not anticipate.
But that is a reason to label the issue as developing law, not to invent a new rule today.
There is also a second countercase: in many businesses, AI will remain functionally equivalent to advanced software. Tax law has long dealt with automation without treating every machine or server as a separate manager of the company.
Scenarios, not forecasts
Under human-attribution continuity, existing rules continue to focus on directors, officers, employees, fixed places and legally attributable decisions even as agents become more capable.
Under administrative clarification, tax authorities and the OECD publish guidance on how agentic systems interact with residence, agency and PE concepts.
Under new nexus concepts, legislatures or treaties eventually create specific rules for highly autonomous digital business activity.
Observable triggers are OECD commentary, domestic guidance, court decisions, tax rulings and treaty amendments.
Practical consequences
Companies using AI agents should document governance before a tax dispute forces them to reconstruct it.
Who can bind the company? Which decisions require a director or officer? Which systems can spend money or enter contracts? Where are those permissions set? Where are exceptions approved? Which employees or founders supervise the system?
Board minutes should reflect real governance rather than ceremonial meetings.
Delegation matrices should distinguish operational automation from strategic authority.
System logs can support evidence, but they do not replace legal analysis.
A highly automated company can be globally distributed.
It is not automatically globally resident nowhere.
