Gifting Cash vs Buying Property for Your Child in the UK: A Parent's Decision Guide

Gift cash, or buy the property? These are two different questions

The short answer: gifting cash so your child buys, versus buying directly and registering the home in your child’s name, are structurally different routes. The difference is not about affection — it is about inheritance tax, stamp duty and how legal title is held. Once you see where these two questions diverge, the right choice for your family becomes far clearer.

When you decide to help a child studying or starting out in the UK, you generally have three common options: gift a sum of cash so the child buys in their own name; fund the purchase and register the property in the child’s name; or hold the property jointly between parent and child. Each carries different tax and legal consequences. In this guide, IREIS Properties unpacks every decision point so you can see the whole picture before you commit. If you would like the wider framework first, read our pillar guide, the complete guide to buying UK property for your children.

Route one: gift the cash, and let your child buy

Direct answer: gifting cash to an adult child who then buys in their own name is the simplest structure — it makes the child the sole legal owner and keeps the parent’s role cleanly at the “donor” end.

The UK has no separate lifetime gift tax. According to HMRC/GOV.UK, an outright gift is a Potentially Exempt Transfer (PET): if the donor survives 7 years after making the gift, it falls fully outside inheritance tax; if the donor dies within 7 years, the gift re-enters the estate for tax purposes. This is the well-known “7-year rule”.

There are also everyday exemptions to draw on. According to GOV.UK, each person has an annual gift exemption of £3,000 (and if one year’s allowance is unused, it can be carried forward once), plus a small-gifts exemption of £250 per recipient each year. These sit outside inheritance tax and, used well, allow funds to move with ease over time rather than in a single large transfer.

For many overseas parents, this route’s appeal is its clarity. The child becomes the sole owner from day one, holds the property in their own name, and your role as donor is clean and well documented. There is no shared title to unwind later and no question of whose name sits where; the inheritance tax position rests on a single, understandable test, the 7-year rule. IREIS Properties finds that families who value simplicity and a clear succession of ownership often gravitate to this path, particularly where the child is already an adult and settled enough to take on the responsibilities of ownership.

How taper relief actually works

Direct answer: taper relief reduces the tax, not the value of the gift, and it applies only to gifts made 3 to 7 years before death that exceed the nil-rate band.

According to HMRC, for gifts made between 3 and 7 years before death that exceed the nil-rate band, taper relief reduces the inheritance tax payable on a sliding scale according to how long the donor survived. The key point: it adjusts the tax due, not the gift’s value, and it only bites where gifts exceed the threshold. How it applies to a particular family varies, so consult a qualified UK tax adviser.

Don’t forget the gifted-deposit letter

Direct answer: if your child will use the cash as a mortgage deposit, lenders will almost always require a formal gifted-deposit letter.

Where a child applies for a mortgage and the deposit comes from a parental gift, the lender will typically require a signed gifted-deposit letter stating clearly that the money is a non-repayable gift and that the donor holds no stake in the property. In parallel, under the Money Laundering Regulations 2017, solicitors and lenders will ask you to document and evidence the source of funds. Preparing these papers early makes the whole process far smoother.

Route two: parents buy directly, registered in the child’s name

Direct answer: if your child is still a minor, you cannot register the property directly in their name — anyone under 18 cannot hold legal title to UK land.

According to s.1(6) of the Law of Property Act 1925, a minor under 18 cannot hold legal title to UK land. A property bought “for” a minor is therefore held by adult trustees, most commonly under a bare trust: the property is registered in the trustees’ names, but the beneficial interest belongs to the child, who takes legal title at 18.

This route is more intricate in planning terms, involving trust structures, trustee duties and arrangements for the eventual transfer. A bare trust is a recognised and well-understood vehicle, but it carries real responsibilities: the adult trustees hold and manage the property until the child reaches 18, and the beneficial interest belongs to the child throughout. Decisions about who acts as trustee, how the purchase is funded, and how the eventual transfer is handled all deserve careful thought rather than a hurried arrangement. The structure must be tailored to your family’s circumstances, so consult a qualified UK tax and estate adviser before deciding.

There is also a timing dimension worth weighing. Because the child takes legal title automatically at 18, parents who set up a bare trust are, in effect, choosing the moment the next generation gains full control. For some families that timing is exactly right; for others, a different structure may suit better. This is precisely the kind of nuance that rewards proper advice early, rather than retro-fitting a fix once contracts are exchanged.

Adding a parent to the title: the stamp duty pivot

Direct answer: once a parent is named as a co-purchaser, the whole transaction is tested across all co-owners — so if any co-owner already owns a residential property anywhere in the world, the additional-property stamp duty surcharge applies to the entire purchase, even if it is the child’s first home.

This is the point families most often overlook. Out of care, many parents want to be on the title so they can keep an eye on things — but for stamp duty (SDLT), co-purchasers are assessed together. In other words, if a parent already holds any residential property (whether in the UK or overseas), the purchase can fall into the additional-property category, even when the child themselves is a first-time buyer.

Stamp duty rules differ depending on whether you are an overseas buyer, a first-time buyer, or already own another home, and the figures change accordingly. Rather than working it out yourself, use our UK Stamp Duty Calculator to calculate your family’s exact situation. IREIS Properties recommends settling this step before you decide how to register title; it is often where the cost gap between the two routes is widest, and it is far easier to model in advance than to discover at completion.

It is worth pausing on why this catches so many well-meaning parents off guard. The instinct to be on the title comes from a good place: a wish to stay close to the asset and to support the child. But the calculation does not look at intentions; it looks at the facts of who owns what. A parent with a family home back home, plus perhaps a buy-to-let, will usually be treated as already owning residential property for these purposes. The practical takeaway is simple: decide how title will be held with the stamp duty position fully understood, not as an afterthought.

The overarching premise: UK property is always within UK inheritance tax

Direct answer: regardless of where the owner lives or is tax-resident, UK residential property is a UK-situated asset and is always within the scope of UK inheritance tax.

According to GOV.UK, from 6 April 2025 the UK moved to a residence-based inheritance tax regime, replacing the previous domicile-based system: whether you are exposed to UK inheritance tax on worldwide assets now turns on being a long-term UK resident (UK-resident for at least 10 of the prior 20 years).

But one overarching premise never changes, whatever the regime: UK residential property is a UK-situated asset and is always within UK inheritance tax, regardless of the owner’s residence or tax position. That means that whether or not you or your child are currently UK-resident, this London home remains subject to UK rules at the inheritance level.

For the 2025/26 tax year, according to HMRC/GOV.UK, the inheritance tax nil-rate band is £325,000, with a residence nil-rate band of £175,000 available where conditions are met; both thresholds are frozen to April 2031. These are the framework’s bones; how they apply to your family’s specific planning varies, so consult a qualified UK tax adviser.

So how should you choose?

Direct answer: there is no one-size-fits-all answer — the choice depends on your child’s age, whether the parents already own another home, the family’s inheritance tax exposure, and how quickly and completely you wish to pass assets to the next generation.

If your child is already an adult and you want a clean, simple structure that places the property firmly in their hands, gifting cash for them to buy is often the most composed starting point. If the child is still a minor, the route requires a bare trust or similar structure and more specialist design. And before naming a parent on the title, always run the cost through a stamp duty calculator first.
