First-time buyer's relief gets treated as a simple concept: never bought before, get a discount. In practice it's one of the more tightly drawn reliefs in SDLT, and we see it fail for reasons that have nothing to do with whether someone genuinely feels like a first-time buyer. An inherited share nobody remembers, a joint purchase with a partner who owned a flat a decade ago, or simply buying with letting rather than living in mind, any one of these is enough to lose the relief entirely. Worth understanding properly before you assume it applies, particularly if you're a developer or investor whose first purchase doesn't look like a conventional first home.
What the relief actually gives you
For a genuine first-time buyer purchasing a residential property to live in, SDLT is charged at 0% on the first £300,000 of the price, with the standard 5% rate applying to the slice between £300,001 and the relief's upper limit of £500,000. Above £500,000, the relief doesn't taper, it stops applying entirely, and standard SDLT rates are charged on the full price from £0 as though the buyer were not a first-time buyer at all. On a £300,000 purchase, the relief is worth up to £5,000 compared with the standard residential rates. It's a meaningful saving, but a narrow one, and the eligibility test is where most of the actual disputes happen.
"First-time buyer" means something more specific than it sounds
To qualify, a buyer must never have owned, or been treated as owning, a major interest in a residential property anywhere in the world, at any point, before the purchase in question. That test has three features that regularly trip people up:
- It isn't limited to the UK. Property owned abroad counts. Someone who has never bought in the UK but co-owns an apartment with family overseas doesn't meet the definition.
- It doesn't matter how the interest was acquired. A share inherited on a parent's death, a property gifted by a relative, or an interest received as part of a divorce settlement all count as prior ownership, in exactly the same way as a purchase would. It makes no difference that no money changed hands or that the buyer never chose to acquire it.
- It doesn't matter whether the buyer ever lived there. A small inherited share in a property that was sold within months, with the proceeds never even touched by the buyer personally, is still enough to disqualify someone from first-time buyer status on every future purchase.
We see this catch out clients who genuinely believed they were first-time buyers right up until a conveyancer asked the question properly. A 5% share in a grandparent's house, left to several grandchildren and sold on within the estate administration, is a common example. Nobody involved thought of themselves as a property owner at the time. HMRC's test doesn't care.
Joint purchases: it's all or nothing
Where a property is being bought by more than one person, every named buyer has to independently satisfy the first-time buyer conditions. This applies whether the joint buyers are spouses, unmarried partners, or friends buying together. If one buyer meets every condition and the other has owned property before, anywhere, at any point, the relief is lost for the entire transaction. It cannot be apportioned to the share of the buyer who does qualify.
This is the single most common way the relief disappears in practice: a couple buying their first home together, one of whom sold a flat they bought in their twenties before the relationship began. The buyer who has never owned property assumes their own history is what matters. It isn't. The whole purchase is assessed on the weakest link.
Why it fails for a buy-to-let purchase
The relief requires that the buyer intends to occupy the property as their only or main residence. A first purchase made with the intention of letting it out, even genuinely a first-ever property transaction for that buyer, doesn't meet that condition. This is where the relief and the world of property investment part ways most clearly: someone building a portfolio and choosing to make their very first acquisition a buy-to-let, rather than a home to live in, gets no benefit from first-time buyer status at all on that purchase. Standard rates apply, and because it's also a purchase of an additional dwelling relative to the buyer's main residence situation, the position needs checking against the 5% higher rate surcharge on additional dwellings too, which operates on entirely separate rules from first-time buyer status.
The relief is only ever available on the buyer's own home. It has no application to purchases made through a company, in a trust, or with any settled intention other than genuine personal occupation.
Where it does still work well
The relief remains straightforward for the case it was designed for: a genuine first purchase, by someone (or a couple, all of whom qualify) who has never held an interest in residential property anywhere, buying a home priced at £500,000 or under, with a real intention to live in it. It also applies to a first-time buyer's purchase of a qualifying shared ownership lease, where the relief can be claimed either against the share actually being purchased or against the full market value if the market value election was made, and it's worth checking against multiple dwellings relief where a purchase includes more than one dwelling, since the two reliefs interact rather than simply stacking.
Common mistakes
- Assuming an inherited or gifted share in a property doesn't count because no money changed hands or the buyer never lived there
- Not checking a joint buyer's full property history before assuming the couple qualifies together
- Claiming the relief on a first purchase intended as a buy-to-let, where the occupation condition is never met
- Assuming the relief tapers above £500,000, when it in fact stops applying entirely and standard rates apply to the whole price
- Overlooking property owned overseas, which counts toward the first-time buyer test in exactly the same way as UK property
What actually protects you
Before exchange, establish the genuine property history of every named buyer, not just whether they've bought in the UK, and check that the purchase truly is intended as an only or main residence rather than an investment dressed up as a first home. Where a purchase sits close to the £500,000 cap, or involves a shared ownership lease, the numbers are worth modelling properly rather than assuming the relief simply applies because it's someone's first purchase.
Common questions
What is SDLT first-time buyer's relief and who qualifies?
It's a relief that raises the SDLT nil-rate threshold for a genuine first-time buyer purchasing a residential property they intend to live in as their only or main residence, provided the price doesn't exceed the relief's upper limit. To qualify, the buyer, and every joint buyer, must never have owned a major interest in a residential property anywhere in the world before.
Can I claim first-time buyer's relief if I'm buying my first home to let out?
No. The relief requires the buyer to intend to occupy the property as their only or main residence. A purchase made with the intention of letting it out as a buy-to-let, even if it genuinely is the buyer's first ever property purchase, doesn't meet that condition and the relief cannot be claimed.
Does inheriting or being gifted a share in a property in the past stop me being a first-time buyer?
Usually, yes. HMRC's test looks at whether you have ever owned a major interest in a residential property anywhere in the world, not whether you bought it yourself or ever lived in it. A share inherited on someone's death, a gift from a parent, or a small stake in an overseas property can all disqualify you, even if you disposed of it years ago and have no memory of it being relevant.
What happens if I buy jointly with someone who isn't a first-time buyer?
The relief fails for the whole transaction. Every person named as a buyer on the transaction, married or not, has to independently meet the first-time buyer conditions. If even one joint buyer has owned property before, no first-time buyer relief is available on any part of the purchase, and standard SDLT rates apply to the whole price.
