Key takeaways

  • A UAE company creates a UK permanent establishment if you have a fixed place of business in the UK, such as a co-working desk or home office used regularly.
  • HMRC can argue a PE exists if you, as founder, spend over 90 days in the UK meeting clients and managing projects, even under the 183-day residence test.
  • Using a UK mobile number, UK bank account, or UK registered address for your UAE company increases the risk of HMRC challenging your structure.
  • Under Article 5(3)(k) of the UK-UAE treaty, a PE arises if your UAE company provides services in the UK through personnel for a continuous period exceeding the treaty threshold.
  • If HMRC successfully argues a PE, your UAE company pays UK corporation tax at 19% or 25% on profits attributable to UK activities, losing the 0% UAE rate.

You moved your agency to Dubai for the tax advantages. Zero per cent corporation tax, no personal income tax, a lifestyle that makes sense for your business. But if your clients are still in the UK and you’re flying back regularly, or worse, spending months working from a flat in Soho, you have a problem.

HMRC can argue that your UAE company has a UK permanent establishment for UAE company operations. If they succeed, that Dubai company becomes liable for UK corporation tax on the profits attributable to the UK activity. The 0% UAE rate disappears. You are back to 19% or 25% corporation tax, plus the compliance headache of defending your position.

This is not theoretical. HMRC has become more aggressive on cross-border structures, especially where the founder retains significant UK ties. Let’s work through what creates a permanent establishment, how HMRC investigates it, and what you can do to protect your structure.

What Is a Permanent Establishment?

A permanent establishment (PE) is a fixed place of business through which a company carries on its trade, wholly or partly, in another country. Under the UK-UAE Double Taxation Treaty, a PE exists if:

  • You have a fixed place of business in the UK (an office, a co-working desk you use regularly, a room in your house).
  • You have a dependent agent in the UK who habitually concludes contracts on behalf of the UAE company.
  • Your UAE company carries on a construction or installation project in the UK lasting more than 12 months.

For agency founders, the first two are the real risks. You do not need a formal lease. A desk at WeWork in Manchester Northern Quarter that you use for three months a year can be enough. A bedroom in your parents’ house in Bristol Harbourside where you take client calls can count. HMRC looks at the substance, not the label.

Why Agency Founders Are at Higher Risk

Agencies are service businesses. Your product is your team’s time and expertise. If you, the founder, are in the UK meeting clients, managing projects, and signing off work, where is the value actually created?

HMRC’s argument runs like this: the key decision-making and revenue-generating activities happen in the UK. The UAE company is a shell that holds the contract and the bank account. The real business is in London, Manchester, or Edinburgh.

This is especially dangerous if:

  • Your client contracts are signed in the UK or governed by English law.
  • You have UK-based employees or contractors who report to you directly.
  • You use a UK registered address or UK bank account for the UAE company.
  • You spend more than 90 days per tax year in the UK (even if you stay under the 183-day statutory residence test).

I have seen HMRC open enquiries where the founder spent 120 days in the UK, used a UK mobile number on their email signature, and held client meetings at a London hotel. The UAE company had a bank account in DIFC and a registered address in a business centre. That was not enough. HMRC argued the PE existed, and the founder spent two years and roughly £40,000 in professional fees defending the position.

The UK-UAE Double Taxation Treaty: Article 5

Article 5 of the UK-UAE Double Taxation Treaty defines a PE. It includes standard language about fixed places of business, but it also contains a specific provision for “services” that matters to agency founders.

Under Article 5(3)(k), a PE exists if an enterprise of one state (UAE) furnishes services in the other state (UK) through employees or other personnel, and those activities continue for a period or periods aggregating more than 183 days in any 12-month period.

This is the services PE clause. If you or your staff spend more than 183 days in the UK delivering client work, the UAE company has a PE in the UK. Full stop. The 183 days do not need to be consecutive. They can be spread across multiple trips. And it applies to each individual providing the services.

If you have two UK-based contractors who each spend 100 days working on a project for the UAE company, that is 200 days total. The threshold is met. You have a PE.

What Happens If HMRC Finds a PE?

The consequences are not just a tax bill. They include penalties, interest, and a detailed enquiry that can take years to resolve.

If HMRC determines that your UAE company has a UK PE, they will:

  • Require the UAE company to register for UK corporation tax.
  • Assess corporation tax on the profits attributable to the UK PE. This is not optional. It is backdated to the date the PE was created.
  • Charge interest on any unpaid tax from the original due date.
  • Impose penalties if HMRC believes the failure to notify was due to careless or deliberate behaviour.

The profits attributable to the UK PE are calculated using the “functionally separate entity” approach. HMRC will look at the functions performed, assets used, and risks assumed by the UK operation. They will then allocate a proportion of the UAE company’s total profits to the UK PE.

In practice, this often means 60-80% of the company’s profits end up taxed in the UK, because the founder and the key client relationships are in the UK. The UAE entity is left with a profit margin for its administrative functions and nothing more.

How HMRC Finds You

HMRC does not need a tip-off. They have multiple data sources.

First, the Common Reporting Standard (CRS). UAE banks automatically share financial account information with HMRC for UK residents. If your UAE company bank account shows you as the beneficial owner and you are UK resident, HMRC will see the balances and transactions.

Second, Companies House. If you are a director of UK companies, your home address is on public record. HMRC cross-references this with travel data and visa records.

Third, social media and professional directories. HMRC officers review LinkedIn profiles. If your profile says “Founder, XYZ Agency (Dubai)” but your location says “London” and your activity feed shows you at UK industry events, that is evidence.

Fourth, client referrals. If one of your UK clients is under HMRC enquiry and they disclose that they pay a UAE company for services delivered in the UK, HMRC will follow the trail.

You are not hiding. The question is whether your structure can withstand scrutiny.

What You Can Do to Protect the Structure

If you want to run a genuine UAE-based agency that serves UK clients, you need to demonstrate real economic substance in the UAE. That means more than a registered address and a bank account.

Here is what a defensible structure looks like:

1. Physical Presence in the UAE

You need a real office. Not a virtual desk. A lease in your name, with your name on the door, and evidence that you use it regularly. If you are in Dubai, that means a flexi-desk in a DIFC co-working space with a dedicated address, or a lease in a business park. You should be able to produce utility bills, access logs, and photos.

2. Day-to-Day Management in the UAE

The key strategic decisions about the agency should be made in the UAE. Board meetings, budget approvals, hiring decisions, client strategy sessions. You need minutes, agendas, and attendance records that show where these decisions were made. If all your board meetings are held via Zoom while you sit in a coffee shop in Shoreditch, that is a problem.

3. UK Activity Must Be Limited and Temporary

You can travel to the UK for client meetings and project kick-offs. But those trips should be short, infrequent, and clearly related to specific projects. You should not have a pattern of spending months in the UK. Keep a travel log. Record the purpose of each trip. Stay under 90 days per tax year if possible. And never, ever use a UK address as your correspondence address for the UAE company.

4. No UK Employees or Contractors Reporting to You in the UK

If you have UK-based staff, they should report to a UAE-based manager (which may be you, but only when you are in the UAE). If you are in the UK and they are in the UK, and you are directing their work from a UK location, that is a PE trigger. Consider using a UK service company to employ UK staff, with the UAE company contracting with that service company at arm’s length.

5. Separate Bank Accounts and Invoicing

The UAE company should have a UAE bank account. All client invoices should be issued from the UAE company and paid into that account. Do not route payments through a UK account. Do not use a UK payment processor like Stripe or GoCardless with a UK registered address. If you must use a UK payment gateway, set it up under the UAE company’s name with a UAE address.

The Role of the UK-UAE Double Taxation Treaty

The treaty is your friend, but only if you comply with its terms. Article 5 defines the PE threshold. Article 7 allocates taxing rights. If you have no PE, the UAE company’s profits are taxable only in the UAE. If you have a PE, the UK can tax the profits attributable to that PE.

The treaty also includes a “force of attraction” principle in some cases. This means that if you have a PE in the UK, the UK can tax all profits of the UAE company that are attributable to the PE, even if those profits come from activities that are not directly connected to the PE. This is rare in practice but worth knowing.

If you are serious about the Dubai structure, you should have a tax advisor review your specific facts against the treaty. A generic template will not protect you. HMRC looks at the details.

What If You Are Already at Risk?

If you have been running your agency from Dubai but spending significant time in the UK, you need to act before HMRC opens an enquiry. The worst thing you can do is wait and hope it goes unnoticed.

First, gather your travel records. Passport stamps, flight bookings, calendar entries. Work out exactly how many days you have spent in the UK in each of the last four tax years.

Second, review your client contracts. Where were they signed? Where are the services delivered? Where do your staff work from?

Third, speak to an specialist agency accountant who specialises in cross-border structures. Do not use a generalist. You need someone who understands both the UK tax rules and the UAE substance requirements.

Fourth, consider a disclosure to HMRC under the Worldwide Disclosure Facility or the Contractual Disclosure Facility if you believe there is unpaid tax. Voluntary disclosure significantly reduces penalties.

At Agency Founder Finance, we work with agency founders who have UAE structures. We can help you assess your PE risk, restructure your operations, and make a clean disclosure if needed. Get in touch before HMRC finds you first.

Key Takeaways

  • A UK permanent establishment for a UAE company exists if you have a fixed place of business, a dependent agent, or spend more than 183 days delivering services in the UK.
  • HMRC uses CRS data, Companies House records, and social media to identify potential PEs.
  • A defensible UAE structure requires real substance: an office, day-to-day management in the UAE, and limited UK travel.
  • If you are already at risk, gather your records and speak to a specialist accountant before HMRC opens an enquiry.
  • The UK-UAE Double Taxation Treaty protects you only if you comply with its terms. A PE destroys the tax advantage of the UAE structure.

If your agency structure involves a UAE company and UK clients, do not assume you are safe. Review your facts. Talk to someone who knows the rules. The cost of getting this wrong is far higher than the cost of getting it right.

Frequently asked questions

What counts as a fixed place of business for a UK permanent establishment?
A fixed place of business is any physical location in the UK that your UAE company uses regularly for its trade. This includes a rented office, a co-working desk you use consistently, a room in your home, or even a hotel room you use for extended periods. HMRC does not require a formal lease. They look for a pattern of regular, exclusive, or semi-exclusive use. If you work from the same WeWork desk in Manchester for two weeks every month, that is a fixed place of business.
Can I spend less than 183 days in the UK and still have a PE?
Yes. The 183-day threshold applies to the services PE clause under Article 5(3)(k) of the UK-UAE treaty. But you can also have a PE through a fixed place of business or a dependent agent, even if you spend fewer than 183 days in the UK. For example, if you have a dedicated office in London that your UAE company pays for, and you use it for 60 days a year, that office is a PE. The fixed place of business test has no minimum time threshold. It is about the nature of the presence, not just the duration.
What happens if HMRC finds my UAE company has a UK PE?
HMRC will require the UAE company to register for UK corporation tax and will assess tax on the profits attributable to the UK PE. This is backdated to the date the PE was created. You will also face interest on unpaid tax and potentially penalties if HMRC believes the failure to notify was careless or deliberate. The profits attributable to the UK PE are calculated using a functional analysis, and in practice, 60-80% of the company’s profits may end up taxed in the UK.
Can I restructure my agency to avoid a UK PE after I have already started operating?
Yes, but it is more difficult and carries more risk. You can restructure by moving your physical presence, changing your work patterns, and ensuring all key decisions are made in the UAE. However, HMRC may still argue that a PE existed before the restructuring and assess tax for those earlier periods. A clean disclosure for past periods, combined with a defensible structure going forward, is usually the safest approach. Speak to a specialist accountant before making any changes.
