As partnerships become more international, whether intentionally through overseas expansion or more organically through remote and hybrid working, it is increasingly common for LLPs to have non-UK resident members. But international growth can bring unintended tax consequences.
The rules around cross-border LLPs are complex, particularly when it comes to Permanent Establishment (PE) risk and the way different jurisdictions tax partnerships. In many cases, firms do not realise there is a problem until a tax authority starts asking questions.
If your LLP has overseas members, even where the arrangement feels straightforward operationally, it may be worth taking a closer look at the potential exposure.
Why this matters
LLPs with non-resident members can face a range of tax and compliance challenges, especially where those individuals carry out work overseas connected to UK income, have authority to negotiate or make decisions on behalf of the LLP or are based in jurisdictions with evolving or complex tax rules.
While the LLPs are generally treated as transparent for UK tax purposes, overseas jurisdictions do not always take the same view. Some may treat the LLP itself as taxable, while others may regard the activities of an overseas member as creating a local taxable presence or Permanent Establishment. That can lead to:
- Overseas tax filing obligations
- Local corporation or business tax exposure
- Double taxation issues where relief is difficult to obtain
- Additional reporting and administrative burdens
- Scrutiny from HMRC and overseas tax authorities alike
The challenge is that these issues are often not obvious until the structure is already in place.
When international growth creates hidden exposure: an illustration
Let’s take a fictional example.
Ashborne Rowe LLP is a UK-based professional services firm with 10 partners, including Sarah, a senior member who relocated to Dubai in 2022 to support the firm’s Middle East growth plans. Sarah still works extensively with UK clients. She attends weekly partner meetings remotely, negotiates service contracts on behalf of the LLP and continues to draw profit shares through the UK partnership.
On the surface, nothing appears unusual, but two issues have started to emerge.
In the UK, HMRC has questioned whether Sarah’s activities could create a Permanent Establishment in the UAE and whether profits are being appropriately attributed and taxed.
At the same time, the introduction of UAE Corporate Tax has prompted questions locally about whether Ashborne Rowe LLP itself now has tax registration and filing obligations in the UAE because Sarah is seen as creating a taxable presence there.
The partnership agreement had never been updated following Sarah’s move, and no review had been carried out of the relevant treaty position or local tax implications.
What initially looked like a straightforward relocation has now created a much more complicated compliance exercise, with the potential for penalties, additional advisory costs and reputational risk.
Three common areas of risk
1. Permanent Establishment exposure
A non-resident partner carrying out significant activities overseas on behalf of the LLP may create a Permanent Establishment in that jurisdiction.
This can trigger local tax registrations, filing obligations and potential tax liabilities, alongside complex questions around how profits should be allocated between countries.
Even where a Double Tax Treaty is available, the practical compliance burden can still be significant.
2. Different tax treatment of LLPs
Not every jurisdiction views LLPs in the same way as the UK.
Some countries treat LLPs as transparent, while others tax the LLP itself as a corporate entity. That mismatch can create double taxation issues if both jurisdictions seek to tax the same profits in different ways.
These differences are often overlooked until overseas reporting obligations arise.
3. Transfer pricing and economic substance
Where overseas partners play a key role in generating revenue or managing client relationships, tax authorities may look more closely at where economic value is being created.
This can lead to transfer pricing considerations, profit attribution challenges and the application of local economic substance rules.
Practical steps to reduce risk
There is rarely a one-size-fits-all answer, but there are some sensible steps LLPs can take to strengthen their position:
- Regularly review partnership agreements to reflect current working arrangements, responsibilities and residency positions
- Maintain clear oversight of where non-resident members are based and the activities they undertake
- Assess local tax rules and treaty positions before partners relocate or overseas operations expand
- Document decision-making authority and governance processes carefully
- Seek advice early when circumstances change, as retrospective fixes are often more difficult and costly
