The Bank of Mum and Dad Is Now a Global Phenomenon
The idea of parents helping children buy their first home is not new. What is new is the scale. In the United Kingdom alone, Savills research cited by Connaught Law confirmed that £9.6 billion flowed from family members to first-time buyers in 2024, assisting 173,500 buyers with average contributions of £55,572. That support was involved in 52% of all first-time buyer transactions in the UK that year.
In the United States, the National Association of Realtors 2025 Home Buyers and Sellers Generational Trends Report found that the typical first-time buyer is now 40 years old, a record high. Nearly a quarter of first-time buyers used gifts or loans from friends and family for their down payment. The trend is similar across Australia, Canada, Singapore, and other markets where housing affordability has deteriorated significantly over the past decade.
Helping a child buy property is one of the most meaningful financial decisions a parent can make. It is also one of the most complex, because the tax implications depend on how the help is structured, the jurisdiction, the value of the property, and the broader estate plan. Getting the structure right from the start protects both you and your child.
Start With the Right Questions
Before reaching for a specific structure, it is worth clarifying what you are actually trying to achieve and what constraints apply.
Commerce Trust Company's analysis of high-net-worth property strategies identifies several questions that shape the approach: Is this intended as a gift or a loan? How much can you genuinely afford to give or lend without affecting your own long-term financial plan? Do you want conditions attached, for example around what happens if the child divorces or sells? And how does this contribution interact with what you plan to leave to this child and others in your estate?
Having clear answers to those questions before engaging with any specific structure prevents many of the complications that arise when families make large property contributions without thinking them through in advance.
Gifting a Cash Deposit: The Most Common Route and Its Tax Implications
The most straightforward way to help a child buy a property is to gift them the money for a deposit. This is simple, fast, and widely used. But it carries tax implications in most jurisdictions that are worth understanding clearly.
In the United Kingdom, cash gifts are treated as potentially exempt transfers for inheritance tax purposes. The annual gift exemption allows each parent to give £3,000 per year free of IHT. With carry-forward, two parents who have not used their previous year's exemption can gift up to £12,000 tax-free immediately. Any amount above the annual exemption starts the seven-year clock: if the gifting parent dies within seven years of making the gift, the excess may be added back to their estate for IHT purposes, with taper relief reducing the potential charge in years three to seven. GBAC's guide to gifting for property purchases notes that if the parent's total estate including the gift exceeds the nil-rate band of £325,000, an IHT charge of up to 40% may apply on the excess.
For gifts from surplus income, the gifts out of normal expenditure from income exemption provides a more powerful route. Gifts that are regular, made from income rather than capital, and do not reduce the donor's standard of living are exempt from IHT entirely, with no seven-year rule. This is one of the most underused exemptions available to higher-earning parents.
Mortgage lenders in the UK require that gifted deposits be accompanied by a formal gift letter confirming the money is a genuine gift, not a loan, and that the donor will have no claim on the property. Connaught Law notes that lenders also require source-of-funds verification and identity checks on donors under Money Laundering Regulations 2017. Failing to comply with these requirements can delay or jeopardise the mortgage application.
In the United States, the annual gift tax exclusion is $19,000 per donor per recipient in 2025 and 2026 ($38,000 for a married couple). Gifts above this amount do not automatically trigger tax but reduce the lifetime estate and gift tax exemption, which increased to $15 million per individual under the One Big Beautiful Bill Act signed in July 2025, according to Commerce Trust Company. Amounts below the lifetime exemption simply require filing Form 709 to report the gift; no tax is due until the exemption is fully used.
In Australia, cash gifts to adult children are not subject to gift tax, as Australia abolished gift duties decades ago. However, large gifts may affect Centrelink assessments for parents receiving means-tested benefits, and any impact on estate planning should be reviewed in the context of superannuation death benefit nominations and the overall estate structure.
The Intra-Family Loan: Preserving the Capital While Helping the Child
An outright gift is not the only option. A formal loan from parent to child, properly structured, achieves a similar result while keeping the capital within the family and, in some jurisdictions, offering meaningful tax advantages.
In the United States, the IRS permits intra-family loans provided the loan carries an interest rate at or above the Applicable Federal Rate, which is set monthly by the IRS and is typically lower than commercial mortgage rates. Commerce Trust Company notes that the loan must be documented with a written agreement, a fixed repayment schedule, and actual repayments made according to that schedule. If these conditions are not met, the IRS may reclassify the loan as a gift, triggering gift tax reporting and potentially reducing the parent's lifetime exemption. A properly structured intra-family loan benefits the child by providing a lower interest rate than a commercial mortgage, while the parent receives interest income and retains the principal as part of their estate.
In the UK, parents can lend money to a child with no formal interest requirement, though any interest paid would be income to the parent. The critical distinction is that a loan, unlike a gift, does not start the seven-year IHT clock. The outstanding loan balance remains part of the parent's estate, which may or may not be advantageous depending on the size of the estate and the IHT position. GBAC notes that the child must declare any family loan to their mortgage lender, as the repayment obligation affects affordability calculations and may influence the deals available to them.
One practical advantage of a loan over a gift is the protection it provides if the child's relationship breaks down. A documented loan to a named individual is a liability of that individual's estate; it is not automatically a marital asset in a divorce settlement. A gift, once made, belongs to the recipient and may be treated as marital property depending on the jurisdiction. For parents who want to help without inadvertently funding a future divorce settlement, the loan structure deserves consideration.
Gifting or Transferring Property Directly: The UK Tax Picture
Some parents consider gifting an existing property, such as a buy-to-let or a second home, to a child rather than cash. This approach is structurally different from gifting cash and carries its own tax considerations.
In the UK, gifting a property that is not the parent's main residence is treated as a deemed disposal at market value for Capital Gains Tax purposes, even though no money changes hands. Saffery's analysis makes this plain: CGT is charged on the difference between the market value at the date of the gift and the original purchase price, less allowable costs. The annual CGT exemption is now £3,000 for the 2024/25 tax year, with gains taxed at 18% for basic rate taxpayers and 24% for higher rate taxpayers on residential property.
For Stamp Duty Land Tax, a pure gift of a property with no outstanding mortgage does not trigger SDLT. However, Calculate My Stamp Duty explains that if the recipient takes on an outstanding mortgage as part of the gift, SDLT is charged on the value of that mortgage debt, treated as chargeable consideration. If the child already owns another property, the 5% additional dwelling surcharge applies on top of standard rates.
The Gift with Reservation of Benefit rule is an important pitfall: if a parent gifts a property but continues to live in it without paying full market rent, HMRC may treat the property as still forming part of the parent's estate for IHT purposes, negating the intended inheritance tax benefit of the gift. This rule catches many families who assume a property transfer to a child achieves an immediate IHT saving regardless of occupation.
Trusts: Control, Flexibility, and Long-Term Protection
For families with more complex situations, or where the parent wants to retain a degree of control over how the property is used and eventually passes, a trust structure may be worth considering.
Placing a property in trust for a child's benefit allows the parent to specify conditions on use and distribution, provides a degree of protection from a child's creditors or divorce, and can be structured to remove the asset from the parent's taxable estate if the trust is properly designed and the parent does not retain a benefit from it.
In the UK, discretionary trusts and life interest trusts are the most commonly used structures for property holding. A discretionary trust gives the trustees flexibility to determine how and when the property or its proceeds benefit the beneficiaries. An irrevocable trust, properly structured, can remove the property from the parent's estate after the seven-year IHT period has expired.
In the United States, Commerce Trust Company describes the irrevocable trust route: placing a home in an irrevocable trust removes the property from the taxable estate while providing direction over use and eventual transfer. Some families use intra-family loan trusts, where the parent lends money to a trust that then purchases the property for the child's benefit. Wealthspire Advisors notes that where the loan is to a grantor trust, and the trust is treated as the same income taxpayer as its creator, the interest is paid between the same tax entity, producing no income tax consequence on the interest itself.
Trusts add complexity and ongoing administration costs. They require a solicitor or attorney to establish correctly, and the tax treatment depends on the specific terms and jurisdiction. For the right family and situation, however, they provide a level of control and protection that outright gifts or loans cannot match.
Co-Ownership and Equity Sharing
A fourth option, sometimes overlooked, is for the parent to purchase a share of the property alongside the child rather than gifting or lending the deposit.
Under this approach, the parent owns a defined percentage of the property, recorded in a deed of trust or declaration of beneficial interests. The parent's capital is protected as an asset in their estate rather than transferred away. If the property is sold, the parent recovers their proportionate share of the proceeds. And if the child's relationship breaks down, the parent's equity is separate from the marital estate and not automatically subject to division.
In the UK, this approach has become more widely used, though parents who already own property should note that the 5% SDLT surcharge on additional residential properties applies to any share they acquire. GBAC notes that when the parent eventually sells or gives their share to the child, Capital Gains Tax will be due on any gain in value of that share since acquisition, and the private residence relief will not apply to the parent's share since it is not their main home.
Protecting the Gift: The Divorce Risk
One of the most practically important considerations for parents helping a child buy property is what happens if the child's relationship breaks down. In most jurisdictions, assets brought into a marriage or received as gifts during a marriage are treated differently from jointly earned assets, but the law varies significantly and the lines are not always clear.
In the UK, a gift from parents to a child who is married or in a civil partnership can potentially be taken into account in divorce proceedings, particularly if it has been used to acquire the family home. Connaught Law recommends that parents gifting deposits consider requesting a declaration of trust as a condition of the gift, specifying that the gifted amount is to be returned to the child before the remaining equity is divided. This document creates a legal record of the intended treatment of the contribution and provides meaningful protection in the event of a future divorce.
In the US, gifts from parents to a child are generally treated as separate property and not subject to division in divorce, provided the gift is clearly documented and the child has not commingled it with marital funds. McDonough Capital notes that co-ownership structures, where the parent holds a documented equity share rather than making a gift, offer stronger protection because the parent's interest is legally distinct from the marital estate.
Fairness Among Siblings
A practical consideration that many families underestimate is how a property contribution to one child is perceived by others. If you help one child with a deposit and have other children who receive nothing at this stage, that inequality can create lasting family tension unless it is addressed in your estate plan.
Options include adjusting the inheritance to compensate, treating the contribution as an advance on inheritance and documenting it as such, or making equivalent gifts to other children at an appropriate time. The key is to think through the fairness dimension explicitly, before the gift is made, rather than leaving it to be resolved under the pressure of a future estate administration.
