Non-Dom Abolition and UK Property: What Qatar-Based Professionals Need to Know
The UK abolished the non-dom tax regime on 6 April 2025, moving to a residence-based system for inheritance tax. If you are Qatar-based and own UK property, the direct impact depends on your UK residency status — not your nationality. UK property has always been within scope for UK IHT; what changed is that long-term UK residents now face exposure on worldwide assets, not just UK-sited ones. If you are currently non-resident in Qatar, your position on UK-sited property is largely unchanged — but your planning window has narrowed.
The UK abolished the non-dom regime on 6 April 2025. For Qatar-based professionals who own UK property — or are planning to buy — the announcement generated significant noise, some of it accurate, some of it not.
This article sets out what actually changed, what did not, and where the mortgage structure implications sit. IMS does not provide tax advice. For the tax specifics of your situation, you should work with a qualified UK tax adviser — firms such as KPMG, HaysMac, and Macfarlanes are active in this space for internationally mobile clients. Our role is helping you understand how your ownership and financing decisions interact with those tax considerations.
What actually changed on 6 April 2025
The UK moved from a domicile-based IHT system to a residence-based one.
Under the old rules, non-doms could hold non-UK assets outside the scope of UK IHT, regardless of how long they had lived in the UK. Under the new rules, that protection is gone. If you are UK-resident for 10 of the past 20 years, your worldwide assets — not just your UK property — are exposed to UK IHT at 40% above the nil-rate band.
The nil-rate band itself has not changed. It sits at £325,000 per person. Couples can use all available reliefs, including the residence nil-rate band, up to a combined total of £1 million.
Offshore trusts that previously sheltered UK-resident beneficiaries or settlors from IHT no longer do. That protection ended on the same date.
According to KPMG’s Q2 2025 client surveys, 67% of HNW internationally mobile professionals now cite IHT exposure as their top financial concern. That figure reflects legitimate anxiety — but also some misreading of what actually changed.
What did not change
If you are currently non-resident — living and working in Qatar — the rules around your UK-sited property are essentially unchanged.
UK property has always been within scope for UK IHT, irrespective of the owner’s domicile or residency. That is not new. What changed is the exposure of worldwide assets for long-term UK residents. If you are non-resident in Qatar now, your UK property exposure exists as it always has. No new liability has been created for you by April 2025.
What has changed is your planning window — and that matters.
The FIG relief: what returning expats need to understand
A 4-year Foreign Income and Gains (FIG) relief applies to expats returning to the UK, but only if you have been non-resident for 10 consecutive years before returning. During the FIG period, foreign income and gains are not subject to UK tax — but personal allowances are not available either. The claim is made via Self-Assessment.
For Qatar-based professionals approaching the 10-year non-residency mark, or planning a UK return within the next few years, the timing of that return now carries material tax implications. Pre-April 2025, the planning latitude was wider. Post-April 2025, the window is narrower and the decisions are harder to unwind once made.
Ownership structure: where mortgage strategy and tax planning connect
This is where IMS’s role sits.
If you own UK property worth over £2 million, wealth advisors are currently recommending an ownership structure review — though the right answer isn’t always an SPV. For properties already held inside a company, ATED charges currently run to £32,200 per year and above, while transferring personally held property into an SPV triggers both CGT and SDLT. The question is whether the long-term IHT and succession planning benefits justify those costs — and that calculation is highly individual.
The connection to mortgage strategy is this: the ownership structure you choose — personal name, joint names, SPV, offshore company — determines which mortgage products you can access, which lenders will work with you, and how the purchase is financed. Those decisions are not reversible cheaply once made.
A client who structures a purchase into an SPV for tax reasons, without considering the lender implications, may find that the product range available to them is narrower and more expensive than anticipated. Conversely, a client who chooses personal-name ownership for simplicity, without taking tax advice first, may face an avoidable IHT liability later.
IMS works alongside tax advisers to ensure the mortgage structure reflects the ownership decision — not the other way around. This is not tax advice. It is coordination.
What ECCTA adds to the picture
For overseas buyers, there is a parallel compliance consideration that is often overlooked in the non-dom conversation.
The Economic Crime Act (ECCTA) came into force in late 2025, introducing Failure to Prevent Fraud obligations that make Source of Wealth and Source of Funds pre-verification central to any overseas mortgage application. For clients with complex asset structures — offshore trusts, multi-jurisdictional income, SPV-held assets — the documentation required to satisfy lender compliance has increased significantly.
Most brokers are still mapping their obligations under ECCTA. IMS has embedded these processes from the outset. Our ACSP (Authorised Corporate Service Provider) registration allows identity verification to be completed locally in Qatar, removing the UK solicitor bottleneck that causes delays for clients working with other brokers.
For clients reviewing their ownership structures in the wake of the non-dom changes, ECCTA compliance is not an afterthought. It is part of the conversation from day one.
The practical starting point
If you are a Qatar-based professional and any of the following apply, a conversation with both a tax adviser and a mortgage specialist is warranted:
You own UK property worth over £1 million and have not reviewed your ownership structure since April 2025
You are approaching 10 years of UK non-residency and planning a return
You are planning to purchase UK property and are considering SPV or joint ownership structures
You hold offshore trusts that previously provided IHT shelter for UK-resident beneficiaries
The non-dom abolition has not created new IHT exposure for most Qatar-based expats on their existing UK property. What it has done is make the planning decisions harder to defer — and the interaction between ownership structure, tax planning, and mortgage financing more consequential than it was before.
Frequently asked questions
Does the April 2025 non-dom abolition affect my UK property if I live in Qatar?
If you are currently non-resident in Qatar, the April 2025 changes do not directly increase your IHT exposure on UK-sited property. UK property has always been within scope for UK IHT regardless of domicile. What changed is that long-term UK residents — those resident for 10 of the past 20 years — now face IHT on worldwide assets, not just UK-sited ones. If you are non-resident, your position on UK property is essentially unchanged, though the reforms make the planning implications of returning to the UK significantly more material.
What is the 4-year FIG relief and does it apply to British expats in Qatar?
The 4-year Foreign Income and Gains (FIG) relief applies to individuals returning to the UK who have been non-resident for at least 10 consecutive years. During this period, foreign income and gains are not subject to UK tax. The claim is made via Self-Assessment. However, personal allowances are not available during the FIG period. For Qatar-based expats approaching the 10-year non-residency threshold, or planning a UK return, when you return carries significant financial implications. A qualified UK tax adviser should assess your specific timing.
Should I use an SPV to hold my UK property after the non-dom changes?
Whether an SPV structure is appropriate depends on your residency position, property value, estate planning objectives, and risk profile — not on the mortgage structure alone. Tax and legal advisers including Macfarlanes, KPMG, and HaysMac are advising clients with properties over £2 million to review SPV options, with restructuring costs typically in the £50,000–£150,000 range. IMS does not provide tax or legal advice. Our role is ensuring that the mortgage structure is compatible with the ownership structure your advisers recommend, and that it is financed on the best available terms for overseas buyers.
How does the non-dom abolition interact with UK mortgage applications for Qatar-based buyers?
The tax changes do not directly alter mortgage eligibility. What they affect is the ownership structure question — personal name, joint names, SPV, or corporate wrapper — and that choice directly determines your product access, lender eligibility, and financing terms. Some SPV structures have a narrower lender panel and higher rates than personal-name applications. IMS works alongside your tax and legal advisers to ensure the mortgage strategy reflects the ownership decision from the outset.
What is ECCTA and why does it matter for Qatar-based buyers after the non-dom changes?
The Economic Crime Act (ECCTA), which came into force in late 2025, introduced Failure to Prevent Fraud obligations requiring brokers and lenders to conduct thorough Source of Wealth and Source of Funds verification. For clients reviewing complex asset structures — including offshore trusts, SPVs, or multi-jurisdictional income — documentation requirements have increased significantly. IMS has embedded ECCTA-grade processes from the outset, and our ACSP registration allows identity verification to be completed locally in Qatar, reducing delays and avoiding late-stage application failures.
