Understanding Stamp Duty for First-Time Buyers
Stamp Duty Land Tax (SDLT) — commonly known simply as “stamp duty” — is a tax you pay to the government when you buy a property in England or Northern Ireland above a certain price threshold. For many first-time buyers, the good news is that you may pay significantly less stamp duty than other buyers, or even nothing at all, thanks to dedicated first-time buyer relief.
This relief was first introduced in November 2017 specifically to help people get onto the property ladder by reducing the upfront cost of buying a home. Since then, the thresholds have been adjusted, and understanding exactly how the current system works is essential for any first-time buyer planning to purchase a new build home in 2025 and beyond.
If you’re at the very start of your journey, our step-by-step guide to buying a new build covers the entire process from viewing to completion. For now, let’s focus specifically on how stamp duty relief works, how much you could save, and what happens if your dream new build is priced above the relief thresholds.
Note: If you’re buying in Scotland, you’ll pay Land and Buildings Transaction Tax (LBTT) instead, which has its own first-time buyer relief. In Wales, Land Transaction Tax (LTT) applies with no specific first-time buyer relief. This guide focuses on SDLT in England and Northern Ireland.
Current First-Time Buyer Stamp Duty Thresholds (2025/26)
As of April 2025, the stamp duty thresholds for first-time buyers in England and Northern Ireland are as follows. These rates apply to purchases completed on or after 1 April 2025:
| Price Band | First-Time Buyer Rate | Standard Rate (Non-FTB) |
|---|---|---|
| Up to £300,000 | 0% | 0% |
| £300,001 – £425,000 | 0% (FTB nil-rate band) | 5% |
| £425,001 – £500,000 | 5% | 5% |
| £500,001 – £625,000 | 5% | 5% |
| £625,001 – £925,000 | FTB relief lost — standard rates apply | 5% |
| £925,001 – £1,500,000 | Standard rates apply | 10% |
| Over £1,500,000 | Standard rates apply | 12% |
The crucial numbers to remember are £425,000 and £625,000. If your new build costs £425,000 or less, you pay zero stamp duty as a first-time buyer. If it costs between £425,001 and £625,000, you pay 5% only on the portion above £425,000. But if it costs more than £625,000, you lose the first-time buyer relief entirely and pay stamp duty at the standard rates on the full purchase price.
How the April 2025 Changes Affected First-Time Buyers
Prior to April 2025, first-time buyers benefited from a more generous temporary threshold of £425,000 (nil-rate) with a £625,000 cap, which was introduced in September 2022. From 1 April 2025, the nil-rate threshold for first-time buyers was confirmed at £425,000, maintaining the relief at this level. For non-first-time buyers, the nil-rate band reverted from £250,000 to £300,000. This means the gap between what first-time buyers and other buyers pay has become an important consideration when budgeting for your new build purchase.
How Stamp Duty Relief Works Specifically on New Builds
Stamp duty on new builds works in exactly the same way as on any other residential property purchase — the first-time buyer relief applies based on the total purchase price of the property. However, there are some new-build-specific considerations that first-time buyers should be aware of.
What Counts as the Purchase Price?
The purchase price for stamp duty purposes is the price stated in your contract. For new builds, this includes:
- The base price of the property as listed by the developer
- Any upgrades or extras that are included in the purchase price (e.g., a premium kitchen package or upgraded flooring specified in the contract)
- Any fixtures and fittings that form part of the property (built-in wardrobes, bathroom suites, etc.)
Importantly, if the developer offers you incentives such as a contribution towards your stamp duty, legal fees, or a furniture pack, these do not typically reduce the purchase price for SDLT purposes. The stamp duty is calculated on the agreed purchase price before incentives are applied. However, if the developer reduces the actual sale price (rather than offering a separate incentive), that lower price is what stamp duty is calculated on.
Developer Incentives and Stamp Duty
Many developers offer attractive incentives for first-time buyers, which can include:
- Contribution towards legal fees
- Contribution towards stamp duty costs
- Free flooring or kitchen upgrades
- Deposit contributions
- White goods packages
If the total value of developer incentives exceeds certain thresholds (more than 5% of the property value for properties up to £700,000), HMRC may consider the incentives as “abnormal” and could reduce the purchase price for stamp duty purposes accordingly. Your solicitor will advise you on how any specific incentives affect your stamp duty calculation. For a broader overview of what developers offer, see our guide to negotiating new build incentives.
Worked Example: Stamp Duty on a £350,000 New Build
Let’s say you’re a first-time buyer purchasing a new build apartment for £350,000:
- The entire £350,000 falls within the FTB nil-rate band (£0 – £425,000)
- Your stamp duty bill: £0
- A non-first-time buyer would pay: £0 on the first £300,000 + 5% on £50,000 = £2,500
- Your saving as a first-time buyer: £2,500
Worked Example: Stamp Duty on a £550,000 New Build
Now let’s look at a more expensive new build house at £550,000:
- First £425,000: 0% = £0
- Remaining £125,000 (£425,001 – £550,000): 5% = £6,250
- Your total stamp duty: £6,250
- A non-first-time buyer would pay: £0 on first £300,000 + 5% on £250,000 = £12,500
- Your saving as a first-time buyer: £6,250
Stamp Duty Comparison: First-Time Buyer vs Standard Rates
The table below shows exactly how much stamp duty you’ll pay at various price points, comparing first-time buyer rates against standard rates. This is particularly useful when you’re comparing different new build developments and trying to understand the true cost of each option.
| Purchase Price | FTB Stamp Duty | Standard (Non-FTB) Stamp Duty | FTB Saving |
|---|---|---|---|
| £250,000 | £0 | £0 | £0 |
| £300,000 | £0 | £0 | £0 |
| £325,000 | £0 | £1,250 | £1,250 |
| £350,000 | £0 | £2,500 | £2,500 |
| £375,000 | £0 | £3,750 | £3,750 |
| £400,000 | £0 | £5,000 | £5,000 |
| £425,000 | £0 | £6,250 | £6,250 |
| £450,000 | £1,250 | £7,500 | £6,250 |
| £475,000 | £2,500 | £8,750 | £6,250 |
| £500,000 | £3,750 | £10,000 | £6,250 |
| £550,000 | £6,250 | £12,500 | £6,250 |
| £600,000 | £8,750 | £15,000 | £6,250 |
| £625,000 | £10,000 | £16,250 | £6,250 |
| £650,000 | £17,500 (relief lost) | £17,500 | £0 |
| £700,000 | £20,000 (relief lost) | £20,000 | £0 |
Notice the cliff edge at £625,000. A first-time buyer purchasing at £625,000 pays £10,000 in stamp duty. But if the price is just £625,001, they lose all first-time buyer relief and pay £16,250 at standard rates — an increase of over £6,000 for a single extra pound on the purchase price. This is why it’s so important to be aware of the threshold when negotiating the price of your new build.
FTB Savings at Key Price Points
Maximum FTB saving is £6,250. Relief is completely lost above £625,000.
What Happens If You Exceed the £625,000 Threshold?
The £625,000 cap on first-time buyer relief creates what tax professionals call a “cliff edge”. This means there’s a dramatic jump in your stamp duty bill the moment your purchase price exceeds £625,000 — even by a single pound.
The Cliff Edge Explained
At £625,000, a first-time buyer pays £10,000 in stamp duty (5% on the £200,000 above the £425,000 nil-rate band). At £625,001, the first-time buyer relief vanishes entirely, and you pay stamp duty at standard rates on the whole purchase price — that’s £16,250. The difference of just £1 on the purchase price costs you an extra £6,250 in tax.
This cliff edge is particularly relevant for new build buyers because new build prices are often set by the developer and may not be easily negotiable. However, there are strategies you can consider:
- Negotiate the price down: If a property is listed at, say, £630,000, it’s worth asking whether the developer would accept £625,000 to keep you within the FTB relief threshold. Many developers will understand the significance of this threshold and may be willing to adjust. Read our guide on negotiating with new build developers for tips.
- Consider a different plot: On the same development, a slightly smaller plot or a different house type might come in under £625,000
- Factor in the true cost: A property priced at £630,000 effectively costs £636,500 (with £6,500 extra in stamp duty) compared to a £625,000 property that costs £635,000 total. Sometimes the cheaper option is genuinely better value

How to Claim First-Time Buyer Stamp Duty Relief
The good news is that claiming first-time buyer stamp duty relief is straightforward — your solicitor handles virtually everything for you. Here’s how the process works:
The Claiming Process
- Confirm your eligibility: You must be a genuine first-time buyer — meaning you have never owned a residential property anywhere in the world (including inherited property or buy-to-let investments). Both buyers must qualify if purchasing jointly.
- Your solicitor prepares the SDLT return: After exchange of contracts, your solicitor will prepare the Stamp Duty Land Tax return (form SDLT1) on your behalf, including the claim for first-time buyer relief.
- The return is submitted to HMRC: Your solicitor submits the SDLT return to HMRC within 14 days of completion. The first-time buyer relief is claimed directly on this return — there’s no separate application form.
- Payment is made: If any stamp duty is due (for purchases between £425,001 and £625,000), your solicitor will arrange payment to HMRC from the funds held in their client account.
- HMRC issues a certificate: Once processed, HMRC issues an SDLT5 certificate, which your solicitor needs to register your ownership with the Land Registry.
Who Qualifies as a First-Time Buyer?
HMRC’s definition of a first-time buyer for stamp duty purposes is quite strict. You qualify if:
- You have never owned a freehold or leasehold interest in a residential property in the UK or anywhere else in the world
- You have never inherited a property (even if you sold it immediately)
- You are purchasing the property as your main residence (not as a buy-to-let or second home)
If you’re buying as a couple, both of you must be first-time buyers to claim the relief. If one of you has previously owned a property, neither of you can claim first-time buyer stamp duty relief on the joint purchase.
Frequently Asked Questions
Do I pay stamp duty on a new build under £425,000 as a first-time buyer?
No. If you are a qualifying first-time buyer and the purchase price of your new build is £425,000 or less, you pay zero stamp duty. The entire purchase falls within the first-time buyer nil-rate band, saving you up to £6,250 compared to a non-first-time buyer purchasing at the same price. This is one of the most significant financial advantages available to first-time buyers in the current market.
What if my partner has owned a property before but I haven’t?
Unfortunately, if you’re purchasing jointly and one of you has previously owned a residential property, neither of you can claim first-time buyer stamp duty relief. HMRC requires all buyers named on the purchase to be first-time buyers. In this situation, you’ll pay stamp duty at the standard residential rates. It may be worth discussing with a financial adviser whether there are alternative purchase structures that could work for your situation, though the property must genuinely be owned by the people named on the deeds.
Does first-time buyer relief apply to all new builds?
Yes, first-time buyer stamp duty relief applies to any new build residential property in England and Northern Ireland, regardless of the developer, the property type (house, flat, bungalow), or whether it’s purchased directly from a developer or through a housing association. The only requirements are that you qualify as a first-time buyer, the property will be your main residence, and the purchase price does not exceed £625,000.
Can I claim stamp duty relief if I’m using a Lifetime ISA for my deposit?
Absolutely. Using a Lifetime ISA for your deposit has no impact on your eligibility for first-time buyer stamp duty relief. The two schemes are completely independent. You can benefit from both the 25% government bonus on your LISA savings and the stamp duty relief — making them a powerful combination for first-time buyers. Just ensure that both the LISA property price limit (currently £450,000) and the stamp duty relief cap (£625,000) are met.
I previously owned a property abroad. Do I still qualify as a first-time buyer?
No. HMRC’s definition of a first-time buyer considers property ownership anywhere in the world, not just in the UK. If you have ever owned a freehold or leasehold interest in a residential property in any country, you do not qualify for first-time buyer stamp duty relief in England and Northern Ireland. This includes properties that were inherited, even if you never lived in them or sold them many years ago.
Making the Most of Your First-Time Buyer Stamp Duty Relief
First-time buyer stamp duty relief is one of the most valuable financial benefits available when purchasing your first home. For new build buyers, it can mean savings of up to £6,250 compared to standard rates — money that could go towards furnishing your new home, building an emergency fund, or simply reducing the upfront cost of getting onto the property ladder.
The key takeaways to remember are: you pay zero stamp duty on new builds up to £425,000, the maximum relief is capped at purchases of £625,000 (above which you lose all relief), and the claiming process is handled by your solicitor as part of the standard conveyancing work.
As you plan your budget, make sure to factor stamp duty into your overall calculations alongside all the other costs beyond your deposit.
