Stamp Duty Calculator 2025: What You Need to Know
Introduction
Stamp Duty Land Tax (SDLT) is a tax you pay when you buy property or land in England and Northern Ireland.
Everyone pays this tax when the property you are buying costs more than a certain amount.
The tax applies to both freehold and leasehold properties.
For 2025, the government has set new stamp duty thresholds and rates. These changes affect how much tax you’ll pay when you buy a home. The new rules set different amounts for various price points and buyer types, with specific rules for first-time buyers and people buying second homes.
A Stamp Duty Calculator makes buying a home more straightforward.
You just type in your property price, tell it if you’re a first-time buyer, and note if it’s a second property. The calculator then shows what you’ll pay under the 2025 rules. This helps you in many ways. First, you can add the stamp duty cost to your budget before making offers.
Second, you won’t face surprise costs when you finish your purchase. In addition, if you’re buying near a tax threshold, the calculator can show how a small price change might cut your tax bill significantly. As a result, this tool helps with better planning and might save you money too.

How Stamp Duty Works in 2025
Stamp Duty is a percentage charge on different portions of the value of the house you are buying.
Stamp Duty is charged differently based on whether:
- The property is your primary residence
- If you are a first time buyer
- If you are buying a second property
Let’s dig in to the percentage taxed base on the values within these variations

Who Pays Stamp Duty?
Stamp duty land tax (SDLT) in the UK in 2025 must be paid by the buyer of any property or land in England and Northern Ireland when the purchase price goes above set limits (shown above).
The tax applies to both freehold and leasehold properties, whether you buy outright or with a mortgage.
First-time buyers get special rates with higher thresholds, meaning they pay less tax or none at all on properties under certain values. Buy-to-let investors and those buying second homes pay extra, facing a 3% surcharge on top of standard rates.
The tax must be paid within 14 days of completing the property purchase. For properties in Scotland, Land and Buildings Transaction Tax applies instead, while in Wales, buyers pay Land Transaction Tax, each with their own rates and rules.
Ways to Reduce Your Stamp Duty Bill
You can legally reduce stamp duty in several ways:
- First-time buyer relief – If you’ve never owned a property before, you pay no stamp duty on the first £425,000 in England and Northern Ireland (with lower thresholds in Scotland and Wales).
- Buy property under the threshold – Properties under £250,000 in England and Northern Ireland don’t incur stamp duty (different thresholds apply in Scotland and Wales).
- Transfer property ownership in divorce – Transfers between spouses as part of divorce settlements are usually exempt from stamp duty.
- Purchase mixed-use property – Properties with both residential and commercial elements can qualify for lower commercial stamp duty rates.
- Buy cheaper fixtures separately – Negotiate to buy certain removable fixtures and fittings separately, as these aren’t subject to stamp duty.
- Multiple dwelling relief – When buying multiple properties in one transaction, you might pay stamp duty on the average property value rather than the total.
- Buy property through a company – In some cases, buying through a company structure can reduce stamp duty liability, though this brings other tax considerations.
- Claim back stamp duty – If you sell your main residence and buy a new one within three years, you might reclaim the second home surcharge.
Common Questions About Stamp Duty
When do you pay stamp duty?
Stamp duty is paid by the buyer at the point of property completion, with the tax due within 14 days in England and Northern Ireland or 30 days in Scotland and Wales. Your solicitor typically handles this payment for you, calculating the amount and submitting it to HMRC using funds you’ve provided before the completion date.
How do you pay stamp duty?
You pay stamp duty by submitting a Stamp Duty Land Tax return to HMRC, which is usually handled by your solicitor or conveyancer who calculates the amount due, completes the necessary forms, and makes the payment on your behalf using money you’ve provided before completion. If handling it yourself, you must file the return and pay online through the HMRC website within 14 days of completion in England and Northern Ireland (or 30 days in Scotland and Wales for their equivalent taxes).
What happens if you don’t pay on time?
If you don’t pay stamp duty on time, HMRC will charge an automatic £100 penalty if payment is up to 3 months late, increasing to £200 for delays beyond 3 months. Interest accumulates daily on both the unpaid tax and penalties, compounding your debt. HMRC may also impose additional tax-based penalties ranging from 5% to 30% of the owed amount depending on how late your payment is. For serious cases, HMRC can take legal action to recover the debt, which might affect your credit rating and could lead to court proceedings or enforcement actions against your property.
Can you add stamp duty to your mortgage?
Yes, you can add stamp duty to your mortgage, which means borrowing more money to cover the tax payment. Your lender will need to approve this increased loan amount, and they’ll assess if you can afford the higher monthly payments and if the property value supports the larger mortgage. Adding stamp duty to your mortgage means you’ll pay interest on this tax amount for the life of your loan, significantly increasing the total cost over time. For example, adding £10,000 in stamp duty to a 25-year mortgage at 4% interest would cost you about £5,800 extra in interest. Most financial advisors recommend paying stamp duty upfront if you can afford it to avoid these long-term additional costs.
