HMRC Asset Letters Put Complex Wealth Structures in Focus

Complex Wealth Needs a Clear Borrowing Picture

Property ownership, company interests, overseas income and existing debt should form one coherent account of the proposed financing.

HMRC Seeks More Detail on Wealthy Individuals’ Assets, Putting Complex Ownership Arrangements in Focus

Fresh reporting draws attention to how property, companies and trusts fit together. The same underlying facts can shape a mortgage application, even though tax oversight and lending serve different purposes.

HMRC has sent hundreds of letters seeking meetings and information about wealthy individuals’ property, trusts, companies and other assets, according to The Sunday Times. The reported outreach brings renewed attention to the structures through which substantial private wealth is held.

The letters do not establish that everyone meeting HMRC’s wealth thresholds will be contacted. Nor do they demonstrate that an exit tax is being introduced. Recipients should take advice on the particular correspondence from their tax or legal adviser.

For property borrowing, the development raises a separate practical issue. A person can have considerable wealth while the assets, income and borrowing supporting a proposed transaction sit in different names, entities and countries.

Those arrangements may be entirely legitimate and well advised. They still need to be explained accurately to a prospective lender. The amount someone owns is only part of the assessment; access to that wealth and the obligations attached to it also matter.

The Latest HMRC Population Figure Is 1.3 Million

HMRC’s technical notes for 2025–26, published on 9 July 2026, identify approximately 1.3 million wealthy individuals. That is the latest published figure used here, rather than the 850,000 appearing in some reporting.

For that period, HMRC defined the group as individuals with income of £200,000 or more, or assets worth at least £2m, in any of the preceding three years. This is a customer-group classification, not a statement that every person in it faces an enquiry.

A Wealth Statement Does Not Explain Who Can Borrow

A family’s financial summary might list a London home, an overseas property, investments, business interests and a trust. That can be a useful overview, but it does not necessarily identify the borrower or the assets available to support a loan.

A personally owned home is different from a home owned by a company. Shares in a property company are different from direct ownership of its buildings. Being a beneficiary of a trust does not automatically provide control of its assets or an unconditional right to income.

Before mortgage products are compared, those distinctions need to be established. Otherwise, the application can begin with an attractive net-worth figure and encounter difficulties when the lender asks what the applicant can actually use.

This is also where double-counting can occur. Listing a company’s full value and its underlying property as separate personal assets may overstate the position. Recording the property without its secured borrowing can have a similar effect.

The objective is a useful financing picture: what is owned, by whom, subject to which obligations, and how it relates to the proposed transaction.

A £3m London Home Can Sit Inside a Much Wider Financing Decision

Consider a hypothetical entrepreneur who personally owns a £3m London home with a £1m mortgage. They also own shares in a UK investment company, receive dividends from an overseas business and have an interest in a family trust.

The existing mortgage is approaching the end of its fixed period. The entrepreneur wants to refinance and raise a further £300,000 for home improvements.

A £1.3m mortgage against a £3m valuation would represent approximately 43.3% LTV. That relatively modest ratio may support the security assessment, but it does not settle income, affordability or repayment questions.

The lender still needs to understand the income supporting the proposed payments. The value of the company and the trust interest may contribute to the wider assessment, but neither should automatically be treated as accessible personal cash.

Illustrative questions arising from one borrower’s wider financial position.
Asset or income source What needs establishing Why it affects borrowing
Personally owned London home Title, valuation, mortgage balance and existing lender terms Determines the proposed security and refinancing requirement
UK investment-company shares Ownership, company liabilities and accessible distributions Company value is distinct from personal income or cash
Overseas dividends Payment history, sustainability, currency and supporting records Affects the lender’s assessment of continuing income
Family trust interest Nature of the interest, trustee powers and any established distributions Determines whether and how it can be relevant to the application

A clear explanation can help identify a suitable route early. It can also reveal that a proposed source of repayment is unavailable, or that the client needs to change the amount or timing of the borrowing.

Company Money Is Not Automatically Personal Money

Business owners often retain cash for working capital, future investment or commercial resilience. A company bank balance can therefore be substantial while the owner’s personal funds are relatively limited.

If money is to leave the business for a property transaction, the route needs to be established. A dividend, salary payment, repayment of a director’s loan and a new loan to the owner have different legal, accounting and tax implications.

The client’s accountant and solicitor should advise on those implications. The mortgage adviser then needs to establish whether the lender accepts the proposed arrangement and what evidence it requires.

There is also a practical cash-flow question. Extracting capital to reduce a mortgage may weaken the business that provides the borrower’s income. Conversely, keeping all capital in the business while taking additional personal debt increases the household’s financing obligations.

Neither decision should be made solely to improve the appearance of a mortgage application. The financing needs to fit the business’s continuing requirements and the family’s wider plans.

Does Your Property Borrowing Involve Several Entities or Countries?

Willow can assess the proposed mortgage alongside the relevant ownership, income and debt arrangements, working with your accountant, solicitor and wealth adviser where appropriate.

Overseas Income Needs to Be Both Evidenced and Sustainable

A dividend payment appearing on a bank statement shows that money was received. It may not, by itself, establish whether similar payments are likely to continue or whether the lender will accept them in full.

The assessment may require an explanation of the underlying business, ownership, accounts, payment history and tax records. Requirements differ between lenders and jurisdictions, including the need for translations or additional verification.

The borrower’s future plans matter too. A relocation, business sale or change in role can alter the income available after the mortgage completes. An application based entirely on historic earnings may miss that transition.

Currency introduces another consideration. A sterling payment funded from income in euros, dollars or another currency can become more expensive in that currency even when the mortgage rate is fixed.

The right discussion therefore covers continuing income and the household’s ability to absorb change. It should not rely on converting one recent overseas payment into an assumed annual borrowing capacity.

Existing Debt Can Be Less Visible Than the Assets

A property schedule should include the borrowing attached to each asset, but the review may need to go further. Personal guarantees, company facilities and lending secured against investments can affect the wider financial position.

For example, a borrower may present an investment portfolio as available capital while it is already pledged to support another facility. Its market value and its freely available value are different questions.

Likewise, a company loan may not be a personal monthly payment, but a personal guarantee can still create an obligation that needs to be understood. Its treatment should be assessed rather than omitted because the borrower is not currently making repayments.

Useful records include the borrower named on each facility, lender, balance, currency, security, repayment basis and maturity date. Relevant guarantees and restrictions should sit alongside those details.

This helps identify concentrations of risk, such as several loans requiring repayment around the same time or borrowing in one currency supported by assets and income in another.

Source of Wealth and Source of Funds Answer Different Questions

The Solicitors Regulation Authority distinguishes the way someone accumulated their overall wealth from the origin of money used in a particular transaction.

A client may have become wealthy through a business sale years ago, while today’s property contribution comes from an investment account or a company distribution. The explanation needs to connect the relevant events and transfers.

A bank statement showing a large balance may be one part of that evidence. Depending on the circumstances, advisers may also need sale documents, distribution records or statements showing how funds reached the account.

This does not mean every transaction requires the same documents. The relevant lender and solicitor determine their own requirements. Providing a coherent account of the proposed contribution helps them identify what they need without relying on assumptions.

One Set of Facts Can Support Several Different Assessments

Tax advisers, solicitors and lenders may examine overlapping information for different purposes. Completing one organisation’s checks does not automatically satisfy another’s requirements.

The records should be consistent, with any differences in dates, valuations or accounting treatment explained. Each professional still makes their own assessment.

Trust Interests Need Legal Clarity Before They Become Lending Assumptions

The phrase “family trust assets” can conceal important distinctions. The client might be a trustee, a beneficiary, a settlor or hold more than one role. Those roles do not carry identical rights.

A discretionary beneficiary should not assume that trust capital is available on demand. A history of distributions may be relevant to a lender, but future payments and the legal basis for them require assessment.

If the proposal involves borrowing by trustees or security over trust property, the powers, consent requirements and proposed transaction need specialist legal review. An individual’s personal mortgage application is a different exercise.

Explaining these matters before approaching lenders can avoid a recommendation built around assets the borrower cannot access or pledge. It also gives the legal advisers a concrete financing proposal to assess.

Better Organisation Can Broaden the Discussion Without Guaranteeing Approval

A well-documented application helps a lender understand the case. It does not turn every asset into accepted income or make an unsuitable ownership structure acceptable.

Some borrowers will fit a mainstream lender once their income and liabilities are properly presented. Others may need a specialist lender or private-bank assessment. A larger net-worth figure alone does not determine which route is appropriate.

Where a private-bank proposal includes an investment relationship, compare the complete arrangement. Mortgage pricing, investment requirements, asset restrictions, fees and repayment terms all belong in the decision.

Similarly, a client should not transfer assets or change company ownership merely because it appears to simplify a mortgage enquiry. Those changes can have consequences beyond the loan and require advice before implementation.

Coordination Works Best When There Is a Specific Transaction to Assess

For private-client professionals, a useful financing review starts with the client’s objective: refinancing a home, acquiring another property, releasing capital for a defined purpose or changing how existing debt is structured.

That objective determines which parts of the wider financial picture are relevant. The adviser can then identify the proposed borrower, security, source of payments, client contribution and intended repayment strategy.

Information should be shared through agreed secure channels, with appropriate consent and attention to what each professional actually requires. A comprehensive personal financial file should not be circulated indiscriminately.

Willow’s role is to assess borrowing and explain lender requirements. Tax advisers address the tax position and any HMRC correspondence; solicitors establish legal ownership and authority; investment advisers assess the implications for managed assets.

When those assessments use consistent information, the client can make a better-informed decision about the property finance. The practical benefit is a clearer understanding of what can be borrowed, what must be evidenced and what obligations the arrangement would create.

Frequently Asked Questions

Complex ownership, international income and property borrowing.

Does HMRC’s wealthy-individual definition determine mortgage eligibility?

No. It is a tax-administration classification. Mortgage lenders apply their own borrower, income, security and affordability requirements, and separate regulatory definitions may also be relevant.

Can company-owned assets automatically support a personal mortgage?

No. Establish ownership, existing security and whether funds or support can lawfully be made available. Any company contribution, distribution, loan or guarantee needs appropriate advice and lender acceptance.

What is the difference between source of wealth and source of funds?

Source of wealth explains how overall wealth was accumulated. Source of funds explains the origin of the money used for the particular transaction. The evidence may overlap, but the questions are different.

Does substantial net worth guarantee a large mortgage?

No. Asset values, access to capital, income, existing debt, property suitability and repayment arrangements all matter. Wealth held in an illiquid business or discretionary trust is not equivalent to available personal cash.

What can Willow coordinate with a client’s tax and legal advisers?

Willow can assess the proposed borrowing, document relevant income and liabilities, identify lender evidence requirements and explain financing conditions. Tax compliance, legal ownership and authority to act remain matters for the appropriately qualified advisers.

Important Notice

This article provides general information, not a personal mortgage recommendation or tax, legal, trust, immigration or investment advice. Published on 25 October 2026.

The HMRC outreach is attributed to The Sunday Times. A report about letters does not establish the legal status, scope or response requirements of any individual communication. Recipients should obtain advice on their own correspondence from an appropriately qualified professional.

HMRC’s wealthy-individual classification is distinct from lender eligibility and regulatory definitions used in financial services. The population figure is not a count of people receiving letters.

The entrepreneur example is hypothetical. It assumes a £3m property value and a proposed £1.3m mortgage, producing approximately 43.3% LTV before any financed fees. No valuation, lender acceptance or borrowing capacity is guaranteed.

Company funds, trust interests and overseas assets may be subject to legal, tax, contractual or practical restrictions. Their inclusion in a wealth statement does not establish that they can support a particular mortgage. Borrowing does not determine tax compliance or remove tax liabilities.

Mortgage availability depends on the borrower, income, residence, security, existing commitments and repayment arrangements. Foreign-currency income and asset values can fluctuate. Obtain advice before changing ownership, extracting company funds or pledging assets.

Your property may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.
