Over 300,000 first-time buyer relief claims were processed by HMRC in 2024 alone. That is a lot of people hoping to save thousands on their first home. But here is the thing — many of those claims get spot-checked, and if you get it wrong, the penalties can be unlimited. I have been writing about UK property taxes for years, and the single most common question I hear is some version of “Am I actually eligible?” The rules are full of traps that catch people out, especially around shared ownership, property owned abroad, and what counts as a first home. Here is what you actually need to know.
If you are buying with someone else, their history matters just as much as yours. And if you have ever owned a property abroad, that can disqualify you entirely. Before you sign anything, you need to understand exactly where you stand. A property lawyer can review your specific situation, but the basics are something every buyer should know cold. Let me walk you through them.
What First-Time Buyer Relief Actually Covers
The most important thing to understand is that this relief is not a general discount — it is a specific exemption on the first £300,000 of a property you intend to live in as your main home. If the purchase price is between £300,001 and £500,000, you pay 5% on the portion above £300,000. If the price exceeds £500,000, you pay standard Stamp Duty Land Tax rates on the entire amount, not just the excess. That is a hard cutoff with no exceptions.
What I tend to notice is that people assume the relief applies automatically. It does not. You have to claim it by entering the correct relief code — code ’32’ for first-time buyers — in box 9 of your SDLT return. If you do not fill in the return at all, or you use the wrong code, HMRC will not apply the relief. And if you claim it when you are not eligible, the penalties are unlimited. My first move would always be to check every condition before submitting anything.
Who Loses Out — And Why It Matters
The rules are stricter than most people realise. For example, if you own a commercial property without any residential element, that does not disqualify you. But if you own a mixed-use property that includes any residential component, you lose your first-time buyer status entirely. That catches a lot of people who run businesses from home or own a flat above a shop.
Another common trap involves leasehold vs freehold distinctions. The relief applies to both, but the rules around shared ownership are different. If you are a first-time buyer of a shared ownership property, you can claim relief as long as the market value is £500,000 or less. You can also choose to pay SDLT in stages when the lease is given, which can help with cash flow. But if you bought your shared ownership property before 1 April 2025, different rates applied.
I have seen people assume that because they are buying with a partner who has never owned property, they can still claim the relief. That is not how it works. If either buyer has ever owned a residential property anywhere in the world, the entire claim fails. Ownership share is irrelevant. Even if you only own 1% and your partner owns 99%, you both lose the relief. That is a hard rule, and HMRC checks it.
Where People Go Wrong With Stamp Duty Claims
The mistakes I see most often are not about the big things — they are about the small details that people assume do not matter. Here are the most common ones, backed by what the research actually shows.
Assuming property abroad does not count
This is the biggest one. If you have ever owned a home in another country, you are not a first-time buyer in the UK. HMRC does not limit the definition to UK property. I have spoken to buyers who owned a small flat in Spain years ago and assumed it would not matter. It does. You lose the relief entirely, and if you claim it anyway, you face penalties. The only exception is if the property was purely commercial with no residential element.
Thinking shared ownership is always safe
Shared ownership has its own rules. You can claim relief if the market value of the property is £500,000 or less, and you intend to live there as your main home. But if you choose to pay SDLT in stages, you need to make a market value election. If you do not, the relief may not apply correctly. And if you bought before 1 April 2025, different rates applied — so check the date of your transaction carefully.
Ignoring the trust trap
If a property is held in a trust and you have beneficial ownership — meaning you benefit from it financially — you are disqualified from first-time buyer relief. This applies even if you have no direct control over the asset. It is a technical rule, but HMRC enforces it. If you are unsure whether a trust arrangement affects you, a real estate lawyer can check your specific situation.
Overlooking the Help to Buy interaction
Help to Buy equity loans can be combined with first-time buyer relief on the portion you purchase. But shared ownership rules apply differently to staircasing — the process of buying additional shares in your property. If you staircase later, you may not be able to claim relief on those additional shares. The rules are complex, and getting them wrong can cost you thousands.

| Property Price | Standard SDLT | FTB SDLT | You Save |
|---|---|---|---|
| £200,000 | £1,500 | £0 | £1,500 |
| £300,000 | £5,000 | £0 | £5,000 |
| £400,000 | £10,000 | £5,000 | £5,000 |
As you can see, the saving is real but capped. On a £400,000 property, you save £5,000 compared to standard rates. But on a £500,000 property, the saving is still £5,000 — it does not increase. And above £500,000, you save nothing at all.

How to Claim Stamp Duty Relief — Step by Step
Claiming the relief is straightforward if you know what you are doing. The key is getting the details right before you submit anything. Here is how to do it.
Check your eligibility against every condition
Before you do anything else, run through the full list of conditions. You must never have owned a residential property anywhere in the world. You must intend to live in the property as your main home. The purchase price must be £500,000 or less. If you are buying with someone else, they must also meet these conditions. If any one of these is not met, you cannot claim the relief. A home loan pre-approval can help you confirm your budget before you start looking at properties.
Fill in the SDLT return with the correct code
You must complete a Stamp Duty Land Tax return even if you do not owe any tax. In box 9 of the return, select relief code ’32’ from the dropdown list. If you are claiming a different type of relief — for example, if an employer is buying your home because of a job relocation — use code ’09’ instead. Using the wrong code means HMRC will not apply the relief, and you may have to pay the full amount plus interest.
Keep records of your eligibility
HMRC spot-checks claims. You should keep evidence that you have never owned a property before — for example, a signed declaration from both buyers. If you are buying with a partner who has owned property abroad, that evidence will show the claim is invalid. It is better to know this before you submit than to face a penalty later. If you are unsure about any part of the process, a property lawyer can handle the return for you.
Understand the shared ownership option
If you are buying a shared ownership property, you have a choice. You can either pay SDLT on the full market value upfront (using a market value election) or pay it in stages as you buy more shares. The relief applies in both cases, but the timing is different. If you pay in stages, you only claim relief on each stage as you go. If you make a market value election, you claim the full relief upfront. Which option is better depends on your cash flow and how quickly you plan to staircase.
