What Is the Foreign PE Exemption?
‘Permanent Establishment’ (PE) refers to a fixed place of business abroad through which a UK resident company carries out business. Typically, profits and losses arising in such foreign PEs could be included in UK Corporation Tax (CT). A recent policy change will make profit and loss exemption mandatory for many such PEs. (gov.uk)
Key Changes Effective Dates
- General regime: mandatory exemption of profits/losses from PEs for accounting periods beginning on or after 1 January 2027. (gov.uk)
- Oil & gas sector: earlier effect for such companies conducting extraction or exploration via foreign PEs; applies from 1 September 2026. (gov.uk)
Compliance Implications
UK resident companies with foreign PEs will face new compliance challenges:
- Must stop offsetting losses from foreign PEs against UK profits once the exemption kicks in. Losses before the effective date won’t be usable after. (gov.uk)
- Transitionary rules will limit carry dukes of losses from previous periods, and institutional anti-avoidance rules will prevent timing or artifices to exploit earlier losses. (gov.uk)
Actionable Steps Businesses Should Take
- Identify all foreign PEs and assess how these changes apply to your accounting period (especially if in oil & gas).
- Review prior losses and capital allowances from PEs to understand what can be used before the exemption takes effect.
- Consider whether restructuring overseas activities could mitigate negative tax consequences—for instance by relocating certain activities or modifying how profits are attributed.
- Update accounting and tax reporting systems to isolate PE profits and prepare clean separations pre- and post-the change.
Example Scenario
A UK resident company with a mining operation in Country X has been offsetting losses from that foreign PE against UK profits up to accounting period ending 31 August 2026. Starting from 1 September 2026, those losses will no longer be usable against UK profits if it’s an oil & gas PE. If accounting period straddles these dates, affected proportionally.
Best Practices for Compliance
- Keep detailed records of PE activities, income streams, and historical losses.
- Engage with professional tax advisors to analyse effective dates and transitional rules.
- Monitor forthcoming draft legislation over summer 2026 that will clarify details. (gov.uk)
Staying ahead now will avoid surprises, penalties, and lost opportunities for tax relief when the regime becomes mandatory.
