Buying a property is one of the biggest financial decisions most people will ever make — and stamp duty is one of the largest upfront costs you'll face. Yet many buyers don't fully understand how it works until they're staring at a solicitor's bill. This guide explains exactly how Stamp Duty Land Tax works in 2025/26, with real examples, the latest rates, and everything first-time buyers and landlords need to know.
What is Stamp Duty Land Tax?
Stamp Duty Land Tax (SDLT) is a tax paid to HMRC when you buy a property or land in England or Northern Ireland above a certain value. It must be paid within 14 days of completion — your solicitor or conveyancer typically handles this automatically as part of the conveyancing process.
Scotland uses a separate system called Land and Buildings Transaction Tax (LBTT), and Wales uses Land Transaction Tax (LTT). This guide covers England and Northern Ireland only.
SDLT is calculated using a tiered "slice" system — similar to income tax. You pay each rate only on the portion of the property price that falls within that band, not on the full purchase price.
Current Stamp Duty Rates for 2025/26
The following standard rates apply from 1 April 2025 in England and Northern Ireland:
| Property Value | SDLT Rate |
|---|---|
| Up to £125,000 | 0% |
| £125,001 to £250,000 | 2% |
| £250,001 to £925,000 | 5% |
| £925,001 to £1,500,000 | 10% |
| Above £1,500,000 | 12% |
Important: These rates changed on 1 April 2025. The temporary higher nil-rate thresholds introduced during the pandemic era ended, returning to the standard pre-2022 thresholds. If you completed a purchase before April 2025, different rates applied.
How SDLT is Calculated — A Real Example
Say you buy a home as a home mover for £400,000. Here's exactly how the tax is calculated:
- First £125,000 at 0% = £0
- Next £125,000 (£125,001 to £250,000) at 2% = £2,500
- Remaining £150,000 (£250,001 to £400,000) at 5% = £7,500
- Total SDLT: £10,000
- Effective rate: 2.5% (£10,000 ÷ £400,000)
The key insight is that your effective rate is always lower than the headline rate — because only the slice above each threshold is taxed at the higher rate.
First-Time Buyer Relief 2025/26
First-time buyers benefit from reduced SDLT rates, but the thresholds changed significantly on 1 April 2025:
| Property Value | First-Time Buyer Rate |
|---|---|
| Up to £300,000 | 0% |
| £300,001 to £500,000 | 5% |
| Above £500,000 | Standard rates apply (no relief) |
Note: The first-time buyer nil-rate threshold dropped from £425,000 to £300,000 on 1 April 2025. Buyers who completed before this date benefited from the higher threshold.
Real First-Time Buyer Examples
Buying at £250,000:
- Entire purchase price at 0% = £0 SDLT
- Saving vs standard rates: £2,500
Buying at £400,000:
- First £300,000 at 0% = £0
- £300,001 to £400,000 at 5% = £5,000
- Total SDLT: £5,000
- Saving vs standard rates: £5,000
Buying at £500,000:
- First £300,000 at 0% = £0
- £300,001 to £500,000 at 5% = £10,000
- Total SDLT: £10,000
- Saving vs standard rates: £5,000
Buying at £600,000:
- First-time buyer relief does NOT apply — standard rates apply in full
- SDLT calculated using standard bands from £0
Who Qualifies as a First-Time Buyer?
To qualify for first-time buyer relief, every purchaser on the transaction must be buying their first home. You qualify if you have never previously owned a residential property anywhere in the world — including inherited properties, overseas properties, or properties received as gifts.
If you're buying jointly and one person is a first-time buyer but the other is not, relief does not apply.
Buy-to-Let and Second Home Surcharge
If you're buying an additional residential property — a buy-to-let, holiday home, or second home — you pay a 5% surcharge on top of the standard SDLT rates at every band. This surcharge was increased from 3% to 5% in the October 2024 Budget, effective from 31 October 2024.
| Property Value | Standard Rate | Buy-to-Let Rate |
|---|---|---|
| Up to £125,000 | 0% | 5% |
| £125,001 to £250,000 | 2% | 7% |
| £250,001 to £925,000 | 5% | 10% |
| £925,001 to £1,500,000 | 10% | 15% |
| Above £1,500,000 | 12% | 17% |
Buy-to-Let Example
Buying a £300,000 buy-to-let property:
- First £125,000 at 5% = £6,250
- Next £125,000 at 7% = £8,750
- Final £50,000 at 10% = £5,000
- Total SDLT: £20,000
- vs standard rate: £5,000 — the surcharge adds £15,000
When Does the Surcharge Apply?
The surcharge applies if at the end of the transaction you own two or more residential properties. It does not apply if you are replacing your main residence — for example, if you sell your current home and buy a new one on the same day.
If you buy a new main residence before selling your old one, you pay the surcharge upfront, but can claim a refund within 12 months of selling your previous main home.
How to Pay Stamp Duty
SDLT must be paid as a lump sum within 14 days of completion. There are no payment plans available. In practice, your solicitor or conveyancer handles the SDLT return and payment to HMRC on your behalf — the amount is included in the funds you transfer to them before completion.
If you are buying without a solicitor, you must submit the SDLT return and payment to HMRC yourself using the online service. Missing the 14-day deadline triggers automatic penalties and interest on the unpaid amount.
How to Reduce Your Stamp Duty Bill
While there is no legal way to avoid SDLT entirely on a standard property purchase, several legitimate strategies can reduce your liability:
1. Buy below a threshold. Properties priced just above a band threshold carry disproportionate SDLT. A property at £260,000 costs meaningfully more in SDLT than one at £249,999, since the extra £10,001 pushes into the 5% band.
2. Allocate value to fixtures and fittings. Movable items like curtains, carpets, and white goods are not subject to SDLT. If the seller includes these in the sale, they can legitimately be allocated a separate value in the contract, reducing the SDLT-bearing property price.
3. Use our Stamp Duty Calculator. Before making an offer, use our free Stamp Duty Calculator to understand the exact tax on any purchase price — so you can factor it into your budget and negotiation.
4. Multiple Dwellings Relief. If you're buying more than one residential property in a single transaction, Multiple Dwellings Relief allows SDLT to be calculated on the average price per dwelling rather than the total, which can significantly reduce the bill.

Frequently Asked Questions
How much stamp duty do I pay on a £300,000 property?
As a home mover buying at £300,000 in 2025/26, you pay £5,000 in SDLT. This is calculated as 0% on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the final £50,000 (£2,500). As a first-time buyer at the same price, you pay £0 since the entire price falls within the 0% first-time buyer band.
Do first-time buyers pay stamp duty in 2025/26?
First-time buyers pay no SDLT on properties up to £300,000. For properties between £300,001 and £500,000, first-time buyers pay 5% on the portion above £300,000. Above £500,000, no relief applies and standard rates are charged from £0. The nil-rate threshold dropped from £425,000 to £300,000 on 1 April 2025.
When do you pay stamp duty?
SDLT must be paid within 14 days of completion. Your solicitor or conveyancer will typically collect the funds from you before completion and pay HMRC on your behalf. Late payment attracts automatic penalties starting at £100, rising significantly for delays beyond 12 months, plus interest on the unpaid amount.
Can I claim a stamp duty refund?
Yes, in certain circumstances. If you paid the higher rates surcharge because you owned a second property at completion, but then sold your previous main residence within 12 months, you can claim a refund of the 5% surcharge from HMRC. You must claim within 12 months of the sale of the previous property or within 12 months of the SDLT filing date — whichever is later.
Is stamp duty the same across the UK?
No. England and Northern Ireland use Stamp Duty Land Tax (SDLT) as described in this guide. Scotland uses Land and Buildings Transaction Tax (LBTT) with different rates and thresholds. Wales uses Land Transaction Tax (LTT), also with different rates. If you're buying in Scotland or Wales, the rates in this guide do not apply.
What happens if I miss the stamp duty deadline?
If you miss the 14-day completion deadline, HMRC will charge automatic penalties. The minimum penalty is £100 for up to 3 months late, rising to £200 plus potentially 5% of the unpaid tax for longer delays. Interest also accrues on the unpaid amount from day 15. Your solicitor should prevent this, but if you're handling your own SDLT return, watch the deadline carefully.
Do I pay stamp duty on a shared ownership property?
Shared ownership buyers have two options: pay SDLT on the full market value upfront (which can be more efficient long-term), or pay SDLT only on the share being purchased initially and then pay additional SDLT as you staircase to higher ownership. The right choice depends on your long-term plans — use our calculator or speak to a solicitor for personalised advice.
