Standard Property Purchase
Complete guide to stamp duty on standard freehold and leasehold property purchases.
Key Takeaways
- SDLT becomes payable at substantial performance, when 90% of the purchase price is paid or you take possession, even before legal completion
- The effective date triggers the 14-day filing deadline, meaning substantial performance can force early payment if it occurs before formal completion
- Linked transactions (buying multiple properties from the same seller) are aggregated for SDLT; each property is taxed based on the combined total purchase price
- If a purchase falls through before completion or substantial performance, any SDLT paid can be reclaimed from HMRC within 12 months
- Leasehold purchases pay SDLT on the purchase price only; ground rent is excluded as it's not part of the premium
- Exchange of contracts alone does not trigger SDLT; only completion or substantial performance creates a chargeable transaction
- HMRC requires SDLT returns even on £0 tax transactions if consideration exceeds £40,000, ensuring proper recording of all property transfers
- Solicitors typically pay SDLT on your behalf from completion funds, but the legal liability remains with the buyer throughout the 14-day deadline

What is a Standard Purchase?
A standard property purchase is the most common type of residential property transaction in England and Northern Ireland. Use our stamp duty calculator to estimate tax on your purchase. It covers buying:
- Freehold houses (you own the property and the land)
- Leasehold flats and apartments (you own a lease, typically 99-999 years)
- Existing properties and new builds
- Properties bought as your main residence
Freehold vs Leasehold
With freehold, you own the property and land outright. With leasehold, you own the property for a fixed period (the lease term) and pay ground rent to the freeholder. Both are taxed the same way for stamp duty purposes.
Current SDLT Rates
Stamp Duty Land Tax (SDLT) is calculated using a progressive rate system. You only pay the higher rates on the portion of the price above each threshold. Learn more about how stamp duty is calculated. For the most up-to-date band information, see the current England SDLT rates:
Standard SDLT Rates 2026
| Property Price Band | Rate | Max Tax in Band |
|---|---|---|
| Up to £125,000 | 0% | £0 |
| £125,001 to £250,000 | 2% | £2,500 |
| £250,001 to £925,000 | 5% | £33,750 |
| £925,001 to £1,500,000 | 10% | £57,500 |
| Above £1,500,000 | 12% | No limit |
These rates apply to your main residence only. Additional properties attract a 5% surcharge on top of these rates at all price levels.
First-Time Buyer Relief
First-Time Buyer Advantage
If you've never owned property before, you benefit from a higher nil-rate threshold of £300,000 (instead of £125,000) on properties up to £500,000.
Eligibility Requirements
- You must never have owned a property anywhere in the world
- The property must cost £500,000 or less
- You must intend to live in it as your main residence
- If buying jointly, all buyers must be first-time buyers
First-time buyer relief only applies to properties up to £500,000. Above £500,000, standard rates apply in full.
The Purchase Process & SDLT
When is SDLT Due?
Stamp duty becomes payable when your property purchase completes. You have 14 days from completion to file an SDLT return and pay any tax due. See when to pay for full payment timeline details.
14-Day Deadline
Missing the 14-day deadline triggers automatic penalties starting at £100, plus interest on unpaid tax. Your solicitor typically handles filing, but you remain legally responsible.
How Your Solicitor Helps
In most cases, your conveyancing solicitor will handle the payment. Budget for all purchase costs using our cost of buying calculator:
- Calculate the exact SDLT due based on the purchase price
- Complete and file the SDLT return (form SDLT1) with HMRC
- Pay the tax to HMRC from your completion funds
- Send you the SDLT5 certificate for Land Registry registration
New Builds vs Existing Properties
SDLT applies equally to new build and existing properties. The only difference is timing: with new builds from a developer, completion can occur months after exchange, so budget for the tax payment at completion, not when you exchange contracts.
Step-by-Step: From Offer to SDLT Payment
Understanding the property purchase timeline helps you prepare for when SDLT becomes due:
1. Offer Accepted
No SDLT implications yet. The offer is not legally binding until contracts are exchanged.
2. Surveys and Searches
Your solicitor conducts property searches. Still no SDLT due, and you can pull out without penalty (though you lose survey and legal fees).
3. Exchange of Contracts
You pay a deposit (typically 10%) and the sale becomes legally binding. Still no SDLT due yet. If you pull out after exchange, you lose your deposit but owe no SDLT.
4. Completion Day
The sale completes, you get the keys, and SDLT becomes due. Your solicitor receives the balance of funds including SDLT payment from your mortgage lender or savings.
5. Within 14 Days of Completion
Your solicitor files the SDLT return online and pays HMRC from your funds. HMRC issues an SDLT5 certificate, which your solicitor uses to register your ownership at the Land Registry.
How Your Solicitor Handles SDLT
Most buyers never directly interact with HMRC because their conveyancing solicitor manages the entire SDLT process as part of the property purchase.
What Your Solicitor Does
- Calculates SDLT: Uses the purchase price, your circumstances (first-time buyer, additional property), and property type to calculate the exact tax due
- Requests funds: Includes SDLT in the completion statement showing how much money you need to provide for completion
- Files SDLT1 return: Completes the official SDLT return form online with all transaction details
- Pays HMRC: Transfers the SDLT payment to HMRC electronically from your funds
- Obtains SDLT5: Receives the SDLT5 certificate from HMRC as proof of payment
- Registers ownership: Submits the SDLT5 to Land Registry as part of registering your ownership
While your solicitor handles everything, you remain legally responsible for the accuracy of the SDLT return. Make sure you provide accurate information about your circumstances, especially regarding ownership of other properties.
What If Your Purchase Falls Through?
SDLT is only triggered when a property transaction completes. If your purchase doesn't complete, no SDLT is due, regardless of how far through the process you were.
Before Exchange of Contracts
Either party can pull out without legal penalty. You'll lose money on surveys, searches, and solicitor fees, but you owe no SDLT because no binding contract exists.
After Exchange But Before Completion
If the buyer pulls out after exchange, they forfeit their deposit and may owe the seller damages, but still owe no SDLT because completion hasn't occurred. If the seller pulls out, the buyer can sue for specific performance or damages, but again, no SDLT is due without completion.
After Completion
Once completion occurs, SDLT becomes due even if you later sell the property or the transaction unwinds. The 14-day clock starts from completion day regardless of subsequent events.
Linked Transactions
When you buy multiple properties from the same seller as part of one arrangement, these are "linked transactions" and SDLT is calculated differently.
How Linked Transaction Rules Work
Instead of calculating SDLT separately on each property, HMRC adds all purchase prices together, calculates SDLT on the total, then apportions it back to each property based on its individual value.
Example: Buying Two Properties
You buy two flats from the same developer: one for £200,000 and one for £150,000.
Total value: £350,000
SDLT on £350,000: £6,250
Apportioned: £6,250 split proportionally between the two properties based on their relative values, rather than calculating £1,500 + £500 = £2,000 if treated separately.
Linked transaction rules typically increase the SDLT bill because the combined value pushes into higher rate bands. Always seek professional advice when buying multiple properties together.
Worked Examples
Example 1: £250,000 Property
| Band | Rate | Tax Due |
|---|---|---|
| £0 - £125,000 | 0% | £0 |
| £125,001 - £250,000 | 2% | £2,500 |
| Total SDLT | £2,500 | |
First-time buyer on a £250,000 property pays £0 (nil rate up to £300,000).
Example 2: £400,000 Property
| Band | Rate | Tax Due |
|---|---|---|
| £0 - £125,000 | 0% | £0 |
| £125,001 - £250,000 | 2% | £2,500 |
| £250,001 - £400,000 | 5% | £7,500 |
| Total SDLT | £10,000 | |
First-time buyer on a £400,000 property pays £5,000 (0% up to £300k, then 5% on the remaining £100k).
Example 3: £500,000 Property
| Band | Rate | Tax Due |
|---|---|---|
| £0 - £125,000 | 0% | £0 |
| £125,001 - £250,000 | 2% | £2,500 |
| £250,001 - £500,000 | 5% | £12,500 |
| Total SDLT | £15,000 | |
First-time buyer on a £500,000 property pays £10,000 (0% up to £300k, then 5% on the remaining £200k).
Worked Example: Standard £400,000 Purchase
This step-by-step calculation shows exactly how SDLT is calculated on a typical property purchase.
Purchase Details
- • Property price: £400,000
- • Buyer: Not a first-time buyer
- • Property: Main residence (no additional property surcharge)
- • Location: England
Step-by-Step Calculation
| Band | Rate | Amount in Band | Tax on Band |
|---|---|---|---|
| £0 - £125,000 | 0% | £125,000 | £0 |
| £125,001 - £250,000 | 2% | £125,000 | £2,500 |
| £250,001 - £400,000 | 5% | £150,000 | £7,500 |
| Total SDLT | £10,000 | ||
Explanation
- • 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: £0 + £2,500 + £7,500 = £10,000
Frequently Asked Questions About Standard Purchases
When exactly do I pay stamp duty?
SDLT becomes due on completion day when you legally take ownership and receive the keys. You then have 14 days to file an SDLT return and pay HMRC. Your solicitor typically handles this automatically using funds you provided before completion. The tax is paid from your own funds, not the mortgage.
Does my solicitor handle stamp duty?
Yes. Your conveyancing solicitor calculates SDLT, includes it in your completion statement, files the SDLT1 return with HMRC, pays the tax on your behalf, and obtains the SDLT5 certificate needed for Land Registry registration. While they handle everything, you remain legally responsible for providing accurate information.
What if my property purchase falls through?
No SDLT is due if the transaction doesn't complete. You only owe SDLT when completion happens and ownership transfers. If you pull out before completion (even after exchanging contracts), you owe no SDLT, though you may lose your deposit and face other penalties. Once completion occurs, SDLT is due regardless of subsequent events.
Can I include stamp duty in my mortgage?
No. Mortgage lenders only lend against the property purchase price, not the SDLT or other transaction costs. You must pay SDLT from your own savings. For a £300,000 property with £5,000 SDLT, your mortgage can't exceed £300,000. Budget for SDLT plus solicitor fees, surveys, and moving costs separately from your deposit and mortgage.
What forms do I need for stamp duty?
The main form is the SDLT1 return, filed online with HMRC. Your solicitor completes this detailing the transaction, calculates tax due, and submits payment. HMRC then issues an SDLT5 certificate proving payment, which the Land Registry requires before registering your ownership. You don't normally see these forms as your solicitor handles everything.
