If you are looking for a stamp duty calculator in 2026, the amount you pay depends on the property price, whether you are buying your first home, whether you already own another property and whether you are treated as a UK or non-UK resident for Stamp Duty Land Tax purposes.
For standard residential purchases in England and Northern Ireland, the current SDLT rates are 0% on the portion up to £125,000, 2% on the portion from £125,001 to £250,000, 5% from £250,001 to £925,000, 10% from £925,001 to £1.5 million and 12% on the portion above £1.5 million. Qualifying first time buyers can receive relief, while additional properties and certain non UK resident purchases can be subject to higher rates.
This complete guide explains how the Stamp Duty Calculator 2026 works, how to calculate SDLT step by step, how much you could pay on different property prices, and what changes for first time buyers, second homes, non UK residents, limited companies, commercial property and shares.
What Is a Stamp Duty Calculator?
A stamp duty calculator is a tool that estimates the amount of tax payable when you purchase property or land.
In England and Northern Ireland, this property tax is officially known as Stamp Duty Land Tax, commonly called SDLT. The amount is calculated using different tax bands, which means that different portions of the property price can be taxed at different rates.
For example, if you purchase a standard residential property for £300,000, you do not simply pay one percentage on the entire £300,000. The applicable SDLT rate is applied to each relevant portion of the purchase price.
This progressive system makes a stamp duty calculator useful when you want to estimate the total tax before buying a property.
Stamp Duty Calculator 2026 Rates
The current standard residential SDLT rates for England and Northern Ireland are:
| Property Price Portion | 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% |
These rates apply to a standard residential purchase where the buyer is not subject to higher rates for an additional property or another special SDLT rule.
The calculation is progressive, so reaching a higher band does not mean that the highest rate is charged on the entire property price.
How Does a Stamp Duty Calculator Work?
A stamp duty calculator takes the property price and applies the relevant SDLT rate to each tax band.
For example, consider a standard residential property costing £300,000.
The first £125,000 is charged at 0%, giving £0.
The next £125,000 is charged at 2%, giving £2,500.
The remaining £50,000 is charged at 5%, giving £2,500.
The total SDLT is therefore £5,000.
This example assumes that the buyer is purchasing a standard residential property and that no additional property surcharge, non UK resident surcharge or special relief changes the calculation.
Stamp Duty Calculator for a £300,000 Property
For a standard residential purchase priced at £300,000, the calculation is:
First £125,000 at 0% = £0
Next £125,000 at 2% = £2,500
Remaining £50,000 at 5% = £2,500
Total SDLT = £5,000
The result can be different if the buyer is a first time buyer, purchasing an additional property or subject to another SDLT rule.
Stamp Duty Calculator for a £400,000 Property
For a standard residential property priced at £400,000:
First £125,000 at 0% = £0
Next £125,000 at 2% = £2,500
Remaining £150,000 at 5% = £7,500
Total SDLT = £10,000
The calculation demonstrates why SDLT should be calculated using the relevant portions of Stamp Duty Calculator for a £500,000 Property
For a standard residential property priced at £500,000:
First £125,000 at 0% = £0
Next £125,000 at 2% = £2,500
Remaining £250,000 at 5% = £12,500
Total SDLT = £15,000
An eligible first time buyer can have a different liability because first time buyer relief can apply to qualifying properties costing £500,000 or less.
First Time Buyer Stamp Duty Calculator
First time buyers can qualify for SDLT relief if they meet the relevant conditions.
Under the current rules, eligible first time buyers pay:
0% on the first £300,000
5% on the portion from £300,001 to £500,000
If the property costs more than £500,000, first time buyer relief is not available.
For example, an eligible first time buyer purchasing a £500,000 property would calculate SDLT as follows:
First £300,000 at 0% = £0
Remaining £200,000 at 5% = £10,000
Total SDLT = £10,000
The buyer must meet the relevant requirements for first time buyer relief, including the conditions relating to previous property ownership and the intended use of the property.
Stamp Duty Calculator for Second Home
A second home or additional residential property can be subject to higher SDLT rates.
If buying the new property means that you will own more than one residential property, you will usually pay an additional 5% on top of the standard residential SDLT rates.
This can apply to situations involving:
Second homes
Buy to let properties
Holiday homes
Additional residential properties
Purchasing another property while retaining an existing property
The exact treatment depends on the circumstances of the purchase.
Replacing Your Main Residence
If you are replacing your main residence, the higher additional property rates may not ultimately apply in certain circumstances.
For example, if you purchase your new main residence before selling your previous main residence, you may initially pay the higher rates. If the previous main residence is subsequently sold within the relevant period and the conditions are met, a refund may be available.
Because the rules depend on the timing and circumstances of the transactions, buyers should check the current official guidance before calculating the final amount.
Stamp Duty Calculator for Non UK Residents
Non UK residents can be subject to an additional SDLT surcharge when purchasing residential property in England or Northern Ireland.
Under the current rules, a 2% surcharge can apply to qualifying residential purchases where the buyer is treated as a non-UK resident for SDLT purposes.
The residence test is based on the buyer’s presence in the UK during the relevant period before the transaction.
The additional surcharge can also combine with higher rates for additional properties where those rules apply.
This means that an overseas buyer should not rely on a standard residential stamp duty calculator without checking the non UK resident rules.
Stamp Duty Calculator for Limited Company
A limited company purchasing property can be subject to different SDLT rules from an individual purchasing a home.
Special rules can apply to corporate bodies and certain purchases of residential property by companies.
There are also specific rules for certain higher value residential properties and transactions involving multiple dwellings.
Therefore, a standard residential stamp duty calculator may not provide the final liability for a company purchase.
If a property is being purchased through a limited company, the transaction should be assessed according to the relevant corporate SDLT rules.
Stamp Duty Calculator Commercial Property
Commercial and mixed use property can have different SDLT rates from residential property.
For non residential property and certain mixed use transactions, the current SDLT rates are:
| Property Price Portion | SDLT Rate |
| Up to £150,000 | 0% |
| £150,001 to £250,000 | 2% |
| Above £250,000 | 5% |
For example, a commercial property costing £275,000 can be calculated as follows:
First £150,000 at 0% = £0
Next £100,000 at 2% = £2,000
Remaining £25,000 at 5% = £1,250
Total SDLT = £3,250
This is why a residential stamp duty calculator should not be used for every type of property transaction.
Stamp Duty Calculator for Mixed Use Property
Mixed use property can contain both residential and non residential elements.
A property with a shop and living accommodation is one example of a transaction that may need to be considered under mixed use rules.
The applicable SDLT treatment depends on the nature of the transaction and the property.
For this reason, the property classification should be confirmed before relying on a calculator result.
Stamp Duty Calculator Shares
A property SDLT calculator should not be confused with tax on shares.
When buying shares, the relevant tax may be Stamp Duty Reserve Tax, commonly known as SDRT, rather than Stamp Duty Land Tax.
For many electronic share purchases, SDRT is generally charged at 0.5% of the transaction value, subject to the applicable rules.
Some share purchases made using a stock transfer form can instead be subject to Stamp Duty.
Therefore, someone searching for a Stamp Duty calculator for shares needs a different calculation from someone buying a house or other property.
Stamp Duty Calculator HMRC
For the latest SDLT information, buyers should check the official HMRC and GOV.UK guidance because property tax rules can change.
The official government guidance covers residential SDLT rates, first time buyer relief, higher rates for additional properties, non UK resident rules and other special circumstances.
You can check the official GOV.UK Stamp Duty Land Tax guidance and residential rates before completing your calculation.
Using the official government information is particularly important when your purchase involves a second property, company ownership, a leasehold transaction, a mixed use property or a non UK resident surcharge.
Stamp Duty Calculator for Leasehold Property
Leasehold property can also be subject to SDLT.
When purchasing a leasehold property, SDLT can apply to the purchase price of the lease. There can also be separate SDLT considerations for rent payable under a new lease when the net present value of the rent exceeds the relevant threshold.
This means that a leasehold purchase may require more information than simply entering the property price into a basic stamp duty calculator.
Does Stamp Duty Apply to Every Property Purchase?
SDLT can apply to a range of property and land transactions in England and Northern Ireland.
These can include:
- Houses
- Flats
- Freehold properties
- Leasehold properties
- Certain shared ownership purchases
- Certain transfers of land or property for payment
- However, special rules can apply depending on the transaction.
The applicable treatment can change for commercial property, mixed use property, additional properties, companies, trusts, linked transactions and other specific circumstances.
Stamp Duty in England, Scotland and Wales
The term stamp duty is often used when discussing property tax throughout the UK, but the systems are different.
England and Northern Ireland use Stamp Duty Land Tax, or SDLT.
Scotland uses Land and Buildings Transaction Tax, known as LBTT.
Wales uses Land Transaction Tax, known as LTT.
Therefore, a stamp duty calculator designed for England and Northern Ireland should not be used as the final calculation for a property purchase in Scotland or Wales.
How to Calculate Stamp Duty Step by Step
Step 1: Enter the Property Price
Start with the purchase price of the property.
Step 2: Identify the Property Type
Determine whether the property is residential, commercial or mixed use.
Step 3: Check Your Ownership Status
Consider whether you already own another residential property.
Step 4: Check First Time Buyer Status
If you are buying your first home, check whether you meet the requirements for first time buyer relief.
Step 5: Check Your Residence Status
If you live outside the UK, check whether the non UK resident surcharge applies.
Step 6: Check for Special Rules
Review whether your transaction involves a company, trust, multiple properties, shared ownership, linked transactions or a leasehold.
Step 7: Apply the Relevant Tax Bands
Calculate the tax separately for each portion of the purchase price.
Step 8: Confirm the Result
Compare your calculation with the latest official government guidance before relying on the amount.
When Do You Have to Pay Stamp Duty?
For SDLT transactions in England and Northern Ireland, the SDLT return and payment are generally due within 14 days of the effective transaction date.
This means buyers should consider their SDLT liability before completion so that the required payment and return can be handled within the relevant deadline.
For complex transactions, the correct deadline and filing requirements should be confirmed against the official rules.
Can You Get a Stamp Duty Refund?
In certain circumstances, a stamp duty refund can be available.
For example, a buyer who paid the higher rates because they owned their previous main residence at the time of purchasing a replacement property may be able to claim a refund after selling the previous home, provided the relevant conditions are satisfied.
There are also circumstances in which a non UK resident surcharge can be refunded if the buyer later meets the applicable residence conditions.
Refunds have specific requirements and time limits, so eligibility should be checked before assuming that a payment can be recovered.
What Information Do You Need for a Stamp Duty Calculator?
To calculate SDLT accurately, you may need the following information:
Property purchase price
Property type
Whether the property is your only residential property
Whether you are a first time buyer
Whether you are replacing your main residence
Whether you are treated as a UK resident
Whether the property is being purchased by a company
Whether the property is commercial or mixed use
Whether the transaction involves a leasehold
Having these details available can make the calculation much more accurate.
