The UK Non-dom Reform and Its Record
The abolition of the UK non-domiciled (non-dom) regime from April 2025 was one of the most-watched personal-tax changes in a generation. Its replacement is a four-year residence-based regime for new arrivals to the UK and an inheritance-tax regime tied to UK residence rather than domicile.
The transition created a wave of structural rearrangements in the year preceding the change and in the year following it. Trusts settled before 6 April 2025 were grandfathered into the old regime under transitional provisions; structures established after that date are taxed under the new regime. The rearrangements involved gifts, transfers, settlements, restructurings, and in some cases departures from the UK.
Each of these arrangements left a record. Trust-settlement deeds are not in themselves public, but the connected entities (corporate trustees, holding companies, family-office vehicles) are. Property transactions are public in the UK and in most relevant jurisdictions. Departures from the UK are recorded in HMRC's Statutory Residence Test working; the working itself is private but the consequential changes (the cancellation of a UK tax-resident's UK tax registrations, the registration of a non-UK tax-resident's interest in UK property under non-resident provisions) are visible at the relevant registers.
For a private client who restructured in this period, the audit's reading reflects the structural change. Where the client moved residency, the audit identifies the records that have not yet caught up with the move (a UK directorship still on the register, a property declared under the wrong residence basis, a charity-trustee record at the old address). Where the structure was rearranged, the audit reads the new structure as a primary record and identifies its current visibility.
The practical implication for a client who completed a non-dom restructuring is that the audit is the natural follow-up step. The structure that was set up properly in 2024 or 2025 may have left footprints in 2026 that are now worth reading.
Significant changes to how non-domiciled individuals are taxed have not only altered liabilities; they have altered what gets recorded. Restructurings undertaken in response generate their own filings, elections and disclosures, and the trail of a structure rearranged in haste can say more about a person's affairs than the arrangement it replaced. Reform tends to produce a wave of records precisely as people move to comply with it.
Reviewing what those changes left behind is the natural follow-up step, and it is one that is easy to defer once the immediate planning is done. A structure set up properly in 2024 or 2025 may have left footprints in 2026 that are now worth reading: filings made, elections recorded, connections newly disclosed. Knowing what the record actually shows after the reform, rather than assuming it matches the intention behind the planning, is the work that completes the exercise.
