At Marco Harris, we help buyers think beyond the asking price, and this stamp duty calculator is just one of the support measures that we provide so you can approach your move with a clearer perspective of everything entailed in a purchase.
Key Points About Stamp Duty Rates
- “Stamp duty” is often used as a catch-all phrase, but Stamp Duty Land Tax applies in England and Northern Ireland, Land and Buildings Transaction Tax applies in Scotland, and Land Transaction Tax applies in Wales. GOV.UK confirms SDLT applies in England and Northern Ireland, with different property taxes used in Scotland and Wales.
- From 1 April 2025, standard residential SDLT in England and Northern Ireland starts above the £125,000 UK stamp duty threshold for standard buyers.
- Stamp duty is usually calculated on increasing portions of the purchase price, not as one flat rate across the whole property value.
- First-time buyers may qualify for first-time buyer relief, while second homes, holiday homes, buy-to-let properties and non-UK resident purchases usually attract higher costs.
- A stamp duty calculator can estimate the stamp duty payable, but your solicitor or conveyancer should confirm your final liability before completion.
What Is The Stamp Duty Land Tax?
Stamp Duty Land Tax, known more casually as ‘Stamp Duty’ or often shortened to SDLT, is a property tax paid when land or property is purchased beyond a certain price threshold. For buyers in England and Northern Ireland, the formal name is the Stamp Duty Land Tax (SDLT), whereas Scotland uses Land and Buildings Transaction Tax (LBTT), and Wales uses Land Transaction Tax (LTT).
It’s important for buyers to also be aware that the material differences between the regions extends beyond naming conventions; there are distinct rates and parameters involved in each region. However, our UK stamp duty calculator will account for location before estimating how much stamp duty tax may be due.
When Do Stamp Duty Rates Apply To Me?
Stamp duty can apply when you as an individual operating within the property market purchases anything from freehold property, new or existing leasehold properties, land, a shared ownership scheme property, or any circumstance where you are if you are involved in the transfer of property interests where money or other consideration changes hands.
How much stamp duty paid exactly, however, is dependant on the purchase price, buyer type, property use, ownership position and residency status. For Marco Harris buyers, current stamp duty rates matter because a failure to calculate stamp duty and account for this in your budgeting can lead to serious disappointment down the line, especially when used alongside our mortgage calculator and wider affordability tools. A property may appear affordable based on deposit and mortgage figures alone, but the amount of stamp duty payable can shift the funds you truly have available for offers.
The Marginal System & How To Calculate SDLT (Stamp Duty Land Tax)
HMRC caculate stamp duty on property using a marginal system. Meaning buyers don’t usually pay one single rate across the entirety of the valuations. Instead, different stamp duty rates apply to different portions of the property price.
This is why working out stamp duty manually can be a challenge. Without a property stamp duty calculator, you could be totally oblivious as to how your profile as a buyer can change the bands, thresholds and surcharge position. A first-time buyer, home mover, non-UK resident, second-home buyer and buy-to-let investor may all pay different amounts on the same residential property purchase.
The safest course of action is to gather context from a stamp duty calculator or location-specific tool, then ask your solicitor or conveyancer to confirm the final amount before completion.
Using Our Residential Property Stamp Duty Calculator
A simple stamp duty calculator helps you calculate stamp duty before you make an offer, exchange contracts, or finalise your purchase budget.
To estimate how much stamp duty may be payable, enter:
- Country: England, Northern Ireland, Scotland or Wales
- Property Price: for example, £350,000
- Buyer Type: first-time buyer, home mover, second-home buyer, buy-to-let investor, or additional property buyer
- Residency: UK resident or non-UK resident
- Property Type: residential property purchase, buy-to-let, new lease, shared ownership scheme, mixed-use property or non-residential property
The Marco Harris UK stamp duty calculator will apply the correct rules based on the user’s regional input. The rules in this case meaning application of Stamp Duty Land Tax SDLT calculation rates for buyers local to us, anywhere near Southampton or across England, as opposed to Land and Buildings Transaction Tax rules for Scottish cases or Land Transaction Tax rules for buyers in Wales.
For buyers searching for a stamp duty NI calculator, there is no separate Northern Ireland property tax system impacting how to calculate stamp duty on property, and Northern Ireland follows SDLT rules.
Example 1: £400,000 Main Residence in England
A UK resident in England in 2026 would be required to pay £10,000 of stamp duty on a 400k house:
| Band | Calculation | SDLT |
|---|---|---|
| First £125,000 | 0% | £0 |
| £125,001 to £250,000 | 2% on £125,000 | £2,500 |
| £250,001 to £400,000 | 5% on £150,000 | £7,500 |
| Total Stamp Duty Payable | £10,000 |
Example 2: £300,000 Non-UK Resident Second Home in England
Stamp duty for a 300k house in this case is different because the buyer is a Non-UK resident, and they also have to factor in a difference in the rate of stamp duty for second home purchases. Without first time buyer relief, the second home stamp duty calculator returns the much steeper figure of £26,000. This reflects additional property SDLT rates plus the 2% non-UK resident surcharge.
How to Calculate Stamp Duty in England or Northern Ireland
To work out stamp duty payments due with accuracy, use the full transaction value, not just the mortgage amount. How much stamp duty owed is based not just on the figure paid for the property or land, but it is usually based on the full transaction value, which can include cash, debt taken on, goods, works, services, or other value exchanged as part of the asset transfer. You may sometimes see this referred to as the ‘consideration’.
A standard residential stamp duty calculator for England and Northern Ireland are based on the SDLT bands:
| Purchase Price Band | Standard SDLT Rate |
|---|---|
| Up to £125,000 | 0% |
| £125,001 to £250,000 | 2% |
| £250,001 to £925,000 | 5% |
| £925,001 to £1.5 million | 10% |
| Above £1.5 million | 12% |
SDLT Rates
The UK stamp duty threshold in England and Northern Ireland starts above £125,000 for standard residential buyers, but do not forget that eligible first-time buyers can also enjoy a higher relief threshold as long as the property also qualifies.
The stamp duty on a £300,000 house first-time buyer threshold only applies where all buyers qualify for first time buyer relief and the property costs £500,000 or less.
First Time Buyer Stamp Duty & The UK Stamp Duty Threshold
First-time buyer stamp duty depends on the property price, location and whether every buyer qualifies for first time buyer relief. However, it’s important to note that the UK stamp duty threshold in England and Northern Ireland only starts above £125,000 for standard residential buyers, irrespective of first-time buyer stamp duty relief.
For homes priced between £300,001 and £500,000, first-time buyer stamp duty due amounts to 5% of the portion above £300,000, and standard rates apply beyond that bracket.
| Purchase price | First-time buyer SDLT in England/Northern Ireland |
|---|---|
| £300,000 | £0 |
| £400,000 | £5,000 |
| £500,000 | £10,000 |
| £510,000 | £15,500 |
| For Marco Harris buyers, this is particularly relevant in Hampshire and South Coast markets where many homes sit above the basic SDLT threshold but below the £500,000 relief limit. While a first-time buyer stamp duty calculator can help estimate what may be payable in any case, eligibility for 1st time buyer stamp duty relief requires the involvement of various qualifying considerations. |
Second Home Stamp Duty & Additional Property Stamp Duty
Second home stamp duty comes into play when a buyer gets their hands on an additional residential property and ends up owning two or more after completion. This can include second homes, holiday homes, buy-to-let properties & some homes bought for family members.
For our local customers, this 2nd home stamp duty typically means 5% on top of the standard rate as a premium levied, but additional property stamp duty charges can reach as high as 17%.
| Purchase price band | Additional property SDLT rate |
|---|---|
| Up to £125,000 | 5% |
| £125,001 to £250,000 | 7% |
| £250,001 to £925,000 | 10% |
| £925,001 to £1.5 million | 15% |
| Above £1.5 million | 17% |
| The accuracy of a second house stamp duty calculator relies on an additional factor, whether the buyer intends to change their primary residence, as there is a distinct difference between stamp duty for second home purchases and stamp duty on a buy-to-let purchase. |
Property Stamp Duty Calculator Results By Price
To get a better grasp of what 2026 stamp duty rates will develop into in a real-world scenario. These example findings from the Marco Harris UK stamp duty calculator may provide some perspective of realistic SDLT, LBTT or LTT before you’ve finalised your purchase budget.
Stamp Duty for a 300K House
Stamp duty for 300k house purchases in England or Northern Ireland typically amounts to £5,000 if it is the buyers main residence. An eligible first-time buyer pays £0 because the property falls within the £300K first-time buyer relief threshold. As for the additional property buyer with a purchase falling into this bracket, they usually have to pay £20,000 under additional property stamp duty rates.
Stamp Duty on a 400K House
Eligible first-time buyers can pay as little as £5,000 stamp duty on 400k house purchases because first time buyer stamp duty applies only to the portion above £300,000. However, a UK resident home mover without the deduction will pay £10k and additional property stamp duty in this bracket will command a hefty £30k.
Stamp Duty on a 500K House
How to calculate SDLT begins to get trickier as the prices increase further, with stamp duty on a 500K house escalating regardless of the buyer’s circumstances. Beyond £500K, the SDLT calculator becomes a resource everyone should rely on, as miscalculations could prove very unfortunate when the amount of stand duty payable has grown into a very significant figure.
These examples may shed some light as to why a reliable stamp duty calculator will always ask about buyer type, ownership status and residency before estimating how much stamp duty on property applies, and why pairing it with an up-to-date South Coast property search can help you compare real homes against your budget.
Land and Buildings Transaction Tax Rates In Scotland
In Scotland, the relevant tax is Land and Buildings Transaction Tax (LBTT). How much stamp duty on property owed is determined by the sum of LBTT band rates due. Revenue Scotland calculate LBTT as an increasing portion of the property price.
First-time buyer relief in Scotland increases the nil-rate band to £175,000. Stamp duty on buy to let purchases is structured similarly to the English tax system, and stamp duty for second home purchases holds an equivalent tax in Scotland in the form of Additional Dwelling Supplement (ADS), which is currently 8% for transactions on or after 5 December 2024.
| Purchase price | LBTT rate |
|---|---|
| Up to £145,000 | 0% |
| £145,001 to £250,000 | 2% |
| £250,001 to £325,000 | 5% |
| £325,001 to £750,000 | 10% |
| Above £750,000 | 12% |
Land Transaction Tax Rates In Wales
In Wales, the relevant tax is the Land Transaction Tax (LTT) following the Welsh Government’s replacement of the SDLT on the 1st of April 2018. Similar to the Scottish system, these main residential LTT rates apply to the portion of the price within each band of the rate accordingly.
Often a topic of contention in recent times, Wales does not currently offer separate first-time buyer relief. However, higher residential LTT rates do still apply when buying an additional residential property. Since December 2024, Welsh higher residential rates have ranged from 5% to 17% depending on the price band.
| Purchase Price | Main Residential LTT Rate |
|---|---|
| Up to £225,000 | 0% |
| £225,001 to £400,000 | 6% |
| £400,001 to £750,000 | 7.5% |
| £750,001 to £1.5 million | 10% |
| Above £1.5 million | 12% |
| Example Equivalents To Normal Stamp Duty Rates Scenario | Estimated Tax |
| ——————————————————— | ————— |
| £300,000 home in Edinburgh, not a first-time buyer | £4,600 LBTT |
| £350,000 main home in Cardiff | £7,500 LTT |
When You Need to Pay Stamp Duty & How the Process Works
Timing matters. Stamp duty, SDLT, LBTT and LTT are usually handled during conveyancing, but the buyer remains responsible for making sure the correct return is filed, and the correct tax is paid.
England and Northern Ireland
For England and Northern Ireland, an SDLT return must be sent to HMRC and the tax must be paid within 14 days of completion. GOV.UK confirms that a solicitor, agent or conveyancer will usually file the return and pay the tax on the buyer’s behalf, then add the amount to their fees.
Scotland
In Scotland, an LBTT return is required for most property purchases above £40,000, even where no LBTT is due. Revenue Scotland states that penalties and interest may apply if the return or payment is not made on time.
Wales
In Wales, buyers must send an LTT return to the Welsh Revenue Authority and pay the tax within 30 days of the day after completion, or the relevant effective date. Welsh Government confirms that the buyer is responsible for the tax return and payment, although a solicitor or conveyancer usually handles this process.
Stamp duty is usually paid as a single lump sum. You cannot normally pay stamp duty directly in instalments, although some buyers choose to increase their mortgage borrowing to help cover wider purchase costs, subject to lender approval and affordability checks.
Some transactions may qualify for reliefs or exemptions. For example, certain transfers after divorce, dissolution of a civil partnership, inheritance without payment, or transactions below specific thresholds may not require the same return or payment process. Your conveyancer should confirm what applies to your purchase.
Latest Stamp Duty Rates 2026 Buyers Guide
The latest stamp duty rates 2026 buyers need to understand depend on location, buyer type, property value, ownership status and residency. Use a UK stamp duty calculator to estimate SDLT, LBTT or LTT before finalising your purchase budget.
For England and Northern Ireland, the most important 2026 SDLT points are:
- Standard residential SDLT starts above £125,000.
- Eligible first-time buyers pay 0% up to £300,000, then 5% from £300,001 to £500,000.
- First time buyer relief is unavailable above £500,000.
- Additional property stamp duty usually adds 5% to the standard SDLT rates.
- Non-UK residents usually pay a 2% surcharge when buying residential property in England or Northern Ireland.
- SDLT is calculated on increasing portions of the property price.
For Scotland and Wales, use LBTT or LTT rules instead of SDLT. This distinction matters for buyers moving between England, Wales, Scotland or Northern Ireland, and for investors comparing property opportunities across the UK.

Do you pay Stamp Duty Land Tax as a first-time buyer?

Is land tax the same as stamp duty?
Land tax is often used casually, but Stamp Duty Land Tax applies only in England and Northern Ireland. Scotland uses Land and Buildings Transaction Tax, while Wales uses Land Transaction Tax, with separate thresholds, normal stamp duty rates and regional calculator rules.

Yes, you may pay stamp duty if you sell your house and buy another property above the SDLT threshold. If you are replacing your main residence, additional property stamp duty usually does not apply, provided the sale and purchase timing rules are satisfied.
