Stamp duty is one of the biggest upfront costs when buying a property. I’ve seen buyers blindsided by a bill they didn’t expect – sometimes thousands of pounds. So let’s cut through the confusion: how much stamp duty you pay depends on where you live, the property price, and your buyer status (first-time buyer, second home, etc.). In this guide, I’ll walk you through the latest rates, show you exactly how to calculate what you owe, and share insider tips to avoid overpaying.

What Is Stamp Duty & Who Pays It?

Stamp Duty Land Tax (SDLT) is a tax you pay when you buy a property or land over a certain price in England and Northern Ireland. (Scotland and Wales have their own systems – LBTT and LTT respectively – but I’ll focus on SDLT here as the most common.) You’re responsible for filing a return and paying HMRC within 14 days of completion. Your solicitor usually handles this, but you’re liable for the final amount.

I’ve seen buyers assume stamp duty is included in their mortgage – it’s not. It’s a separate cash expense you need to budget for. And the rates change often. In 2022, the government introduced a temporary threshold increase to £250,000 for all buyers, but that has since been adjusted. As of now, the standard threshold is back at £125,000, with different rates kicking in above that.

Current Stamp Duty Rates by Property Price (England & Northern Ireland)

Here’s the standard SDLT rates table. These apply for most buyers (not first-time or second home).

Property Price Band SDLT Rate
£0 – £125,000 0%
£125,001 – £250,000 2%
£250,001 – £925,000 5%
£925,001 – £1.5 million 10%
Over £1.5 million 12%

Important: SDLT is a progressive tax – you only pay the higher rate on the portion of the price within each band, not the whole amount. That’s a common misunderstanding. Let me show you an example.

Example Calculation: £300,000 Property

If you buy a house for £300,000 as a standard buyer:

  • First £125,000: 0% = £0
  • Next £125,000 (from £125,001 to £250,000): 2% = £2,500
  • Next £50,000 (from £250,001 to £300,000): 5% = £2,500
  • Total SDLT: £5,000

I’ve seen online calculators get this wrong if you don’t input correctly. Always double-check with HMRC’s own tool or a conveyancer.

How to Calculate Stamp Duty (Step-by-Step)

You don’t need to be a maths whiz. Here’s the manual method I use when advising clients:

  1. Find the purchase price – this is usually the agreed price, not the mortgage amount.
  2. Determine your buyer type – first-time buyer, existing homeowner, second home.
  3. Apply the progressive bands – start from 0% on the first £125,000, then 2% on the portion up to £250,000, etc.
  4. Add any surcharges – additional 3% for second homes, plus for non-residents.
  5. Check for relief – first-time buyer relief (see next section).

Let me walk you through a more complex scenario. Suppose you’re buying a £450,000 second home (buy-to-let):

  • First £125,000: 0%
  • £125,001 to £250,000: 2% on £125,000 = £2,500
  • £250,001 to £450,000: 5% on £200,000 = £10,000
  • Standard SDLT total: £12,500
  • Add 3% surcharge on all bands: 3% on £450,000 = £13,500
  • Total SDLT: £26,000

Ouch. That’s why it’s crucial to know the rules before you bid.

Personal tip: I always tell clients to add at least 5% of the purchase price to their cash budget for stamp duty and moving costs. It saves heartache later.

First-Time Buyer Exemptions & Relief

First-time buyers in England and Northern Ireland can benefit from reduced rates. If you’re a first-time buyer and the property costs £625,000 or less, you pay no SDLT on the first £425,000. On the portion between £425,001 and £625,000, you pay 5%. Above £625,000, standard rates apply with no relief.

Property Price (First-Time Buyer) SDLT Payable
Up to £425,000 £0
£425,001 – £625,000 5% on the part above £425,000
Above £625,000 Standard rates (no relief)

I’ve seen some first-time buyers mistakenly believe they get relief on any property – nope, only up to £625,000. And the relief applies to the first £425,000, so if you buy for £500,000, you pay 5% on £75,000 = £3,750. Still a great saving compared to the standard £12,500!.

Who qualifies as a first-time buyer?

You must never have owned a property anywhere in the world. Joint buyers? All must be first-time buyers to get the relief. If one person has owned before, you lose the exemption.

Second Home & Buy-to-Let Surcharges

Buying an additional property – whether for investment or as a holiday home – triggers an extra 3% surcharge on top of standard rates. This applies to the entire purchase price, not just the higher bands. There’s also a 2% surcharge for non-UK residents (since 2021).

Example: standard buyer on £300,000 pays £5,000. Second home buyer on same price pays £5,000 + (3% × £300,000) = £5,000 + £9,000 = £14,000. That’s nearly triple.

One nuance I’ve seen trip people up: if you’re replacing your main residence but haven’t sold it yet, you may be able to claim a refund if you dispose of your old home within 3 years. HMRC allows a temporary extra 3% surcharge with a reclaim. But the window is tight – mark your calendar.

5 Common Mistakes Homebuyers Make

Over the years, I’ve noticed recurring errors that cost buyers real money:

  1. Assuming the threshold is still £250,000. It reverted to £125,000 in 2025. Always check the current rates on the official HMRC page.
  2. Forgetting the surcharge when buying with a partner who already owns. Even if it’s your first home, if your partner has owned before, you’re both treated as additional property buyers.
  3. Not using a calculator properly. I’ve seen people input the whole price into the 5% band and ignore the progressive nature. Use the HMRC tool or a trusted calculator.
  4. Missing the 14-day deadline. Your solicitor usually handles it, but if you do it yourself, late payment incurs interest and penalties.
  5. Assuming Scotland/Wales rules are the same. They’re not – LBTT and LTT have different thresholds and rates. Always check the local devolved tax.

One personal experience: a client bought a £600,000 house thinking they’d pay nothing as first-time buyers. They didn’t realise the relief only covers up to £425,000. They ended up with a £8,750 bill they hadn’t budgeted for. Don’t be that person.

Frequently Asked Questions

What is the stamp duty for a £250,000 house as a first-time buyer?
If you’re a first-time buyer and the price is £250,000 (under £425,000), you pay £0 stamp duty. The full first-time buyer relief applies.
Do I pay stamp duty on a house I inherit?
Inheritance (gifts) are different – you don’t pay SDLT on inherited property unless you buy out other beneficiaries or pay a cash sum. But you may be liable for Inheritance Tax instead. Always check with a solicitor.
Can I add stamp duty to my mortgage?
Not directly. Your mortgage is for the purchase price only. However, some lenders allow you to increase your loan slightly to cover costs if you have enough equity. Most buyers pay separately.
What happens if I pay stamp duty late?
HMRC charges interest daily from the day after the 14-day deadline. There are also penalties: 5% of the unpaid tax after 6 months, another 5% after 12 months. My advice: let your solicitor handle it and confirm they’ve filed.
Is stamp duty different for leasehold vs freehold?
The rates are the same for both, but the calculation basis can differ. For leasehold, you pay SDLT on the purchase price of the lease plus any ground rent that exceeds certain thresholds. It’s a bit more complex – consider using a professional.

This guide reflects the SDLT rules as of the latest update. For the most accurate calculation, always refer to HMRC’s official rates page.
