Do You Pay Stamp Duty on New Builds?

Last Updated: 21/02/2025

Stamp Duty Land Tax (SDLT) generally applies to new build properties in the UK. However, whether you actually pay any stamp duty depends on several factors:

  • The price you are paying.
  • If you are a first-time buyer.
  • If your developer is offering a stamp duty incentive.

Stamp duty rules and rates vary across the UK and are set by each nation. Wales has its own equivalent, Land Transaction Tax (LTT), with different rates and thresholds.

For example, first-time buyers in England are eligible for relief on properties up to £300,000, but will pay 5% stamp duty on the portion from £300,001 to £500,000. It's important to note that if the property price is over £625,000, you cannot claim first-time buyer relief.

Important: Any purchase that you're starting in now is highly unlikely to complete before the Stamp Duty rules change on 1st April 2025.


What Stamp Duty do you pay on a new build?

Stamp Duty Land Tax (SDLT) is a tax you pay when you buy land or property in England and Northern Ireland. The amount you pay depends on the purchase price and is calculated on a tiered system.

While the specific rates and thresholds vary, the key thing to remember is that the higher the purchase price, the higher the percentage of SDLT you'll pay on that portion of the price.

Developer Stamp Duty incentives

One of the most attractive perks offered by some new build developers is the payment of your stamp duty as part of the deal.

This can represent a significant saving, sometimes up to £25,000, making a new build purchase more affordable. These incentives are particularly valuable for buyers on a tight budget or those looking to maximise their savings.

These incentives can take various forms. The developer might offer to pay the full SDLT amount, effectively eliminating this cost for you. Alternatively, they might contribute a percentage towards it, reducing your SDLT burden.

Some developers may structure incentives in other ways, such as offering upgrades, discounts on extras, interior design, or moving cost contributions.

You must clarify the specifics of the incentive with the developer and get it documented in your contract. Don't assume anything – ask direct questions about what is included and how the incentive is applied.

As this Zoopla article highlights, stamp duty incentives are a common and valuable tool used by developers to attract buyers.

Don't hesitate to ask developers about available incentives, as they can significantly impact your overall costs. In a competitive market, some developers might be willing to negotiate, so it's always worth exploring what options are available.

Who pays Stamp Duty?

While developers may offer incentives to cover the SDLT, the legal responsibility for paying SDLT always falls on the buyer.

Even if a developer promises to pay your stamp duty, your conveyancing solicitor will still handle the actual payment to HMRC (Her Majesty's Revenue and Customs) on your behalf. This ensures that the transaction is legally compliant and that the SDLT is paid within the required timeframe.

Your conveyancing solicitor will handle the calculation and payment of the SDLT to HMRC, typically within 14 days of completion.

They will also ensure that all the necessary paperwork is correctly filed. This is one of the many reasons why it's so important to instruct a qualified conveyancing solicitor when buying a new build property.

When do you pay Stamp Duty on a new build?

The clock starts ticking as soon as you complete on your new build property. Stamp Duty Land Tax (SDLT) is due and must be paid to HMRC (Her Majesty's Revenue and Customs) within 14 days of completion.

Completion is the crucial legal point at which ownership of the property officially transfers from the developer to you. This 14-day window is a strict legal requirement, and failing to meet it can have serious consequences.

Missing the deadline can lead to penalties, including interest charges accruing on the unpaid stamp duty. These penalties can add a significant and unexpected cost to your new build purchase, precisely what you want to avoid. HMRC takes late payments seriously, so it's vital to be prepared and act promptly.

This tight 14-day timeframe highlights the importance of instructing a reliable and efficient conveyancing solicitor to handle your new build purchase.

SAM Conveyancing's panel of solicitors will calculate the correct amount of stamp duty owed, ensure that all the necessary paperwork is correctly filed with HMRC and that your payment is submitted on time.

Can you avoid paying Stamp Duty on a new build property?

You can, but these are limited, rare circumstances and these situations often involve legal or financial arrangements. You should not rely on these possibilities without seeking professional advice.

Your best bet would be to choose a new build property already below the SDLT threshold if you want to avoid the prevailing rate post-April 1st 2025.

Inherited property

If you inherit a new build property through a will, you generally won't pay stamp duty. However, this is a very specific situation, and the property must have been owned by the deceased.

It's also important to note that Inheritance Tax (IHT) might be applicable depending on the value of the estate. Consult with a tax advisor to fully understand the implications of IHT in this scenario.

Negotiating below threshold (Extremely rare)

In theory, it might be possible to negotiate the purchase price of the new build with the developer to fall below the stamp duty threshold.

However, developers are rarely willing to do this, as it would impact their profit margin. This is highly unusual and should not be relied upon.

Fixtures and fittings (Complex and potentially limited)

It may be possible to reduce the amount of stamp duty payable by negotiating with the developer to exclude or separate the cost of fixtures and fittings from the total property price.

This is a complex area, as HMRC has specific rules about what can be classified as a fixture versus a fitting. It depends entirely on how the developer structures the sale and requires detailed documentation. Do not attempt this without expert legal and tax advice, as incorrect classification can lead to penalties.
