Stamp duty on property: a clear guide for UK buyers

Stamp Duty Land Tax (SDLT) is a one-off tax paid by the buyer on residential property purchases in England and Northern Ireland, charged on increasing portions of the purchase price rather than a flat percentage of the whole amount. Your conveyancer normally files the SDLT return and pays the tax at completion, but the legal responsibility sits with you as the buyer. Use the gov.uk SDLT calculator to check your exact liability, and see the worked examples further below for common price points.

How is stamp duty on property calculated?

SDLT is charged on a 'slice' basis, meaning different rates apply to successive portions of the price rather than the whole sum. The method works much like income tax bands: once you cross a threshold, only the amount above that threshold pays the higher rate.

To estimate your bill:

• Identify which bands your purchase price crosses.
• Calculate the tax on each slice separately (band rate × the portion of price within that band).
• Add the results together for your total SDLT.

For a £400,000 purchase by a standard buyer:

• £0 to £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: £10,000

Leasehold purchases add a layer of complexity. Where a long lease involves future rent, SDLT may also apply to the net present value (NPV) of those rents. For most straightforward freehold purchases, the slice method above is all you need. For anything involving a long lease or an unusual consideration, ask your conveyancer to confirm the full calculation before exchange. You can read more about property conveyancing in England to understand how SDLT fits into the wider process.

Current residential SDLT rates for England and Northern Ireland

The rates below apply to standard residential purchases in England and Northern Ireland following the April 2025 reforms. Always verify live rates on gov.uk before exchange, as thresholds can change with little notice.

Note: The April 2025 reforms reduced the standard nil-rate band from £250,000 back to £125,000, materially increasing the tax bill for many buyers compared with the temporary relief that applied before that date.

Surcharges sit on top of these rates. Both are covered in detail below.

Do first-time buyers pay less stamp duty?

Relief is lost entirely if the purchase price exceeds £500,000, at which point standard rates apply to the full amount.

To qualify, every buyer named on the title must meet all of the following:

• Never previously owned a major interest in a residential property anywhere in the world.
• Intend to occupy the property as their only or main residence.
• Be purchasing a property with a lease of more than 21 years remaining (for leasehold purchases).
• Not be purchasing jointly with someone who has previously owned property.

The cliff-edge at £500,000 is worth understanding clearly. A buyer at £500,001 loses all relief and pays the standard rate on the full price, resulting in a bill of £15,000. That single pound of additional purchase price costs an extra £5,000 in tax. For buyers near that threshold, negotiating the price below £500,000 can be worth pursuing. See the cheapest conveyancing options for first-time buyers for further guidance on keeping total purchase costs manageable.

What is the stamp duty surcharge on additional properties?

This covers second homes, buy-to-let purchases, and holiday properties.

The main scenarios where the surcharge applies:

1. You are buying a second home while retaining your existing main residence. 2. You are purchasing a buy-to-let property and already own any other residential property. 3. You are buying a property jointly and one buyer already owns another property. 4. You are purchasing via a company or corporate entity (the surcharge applies to all residential purchases by companies, regardless of how many properties the company owns).

The surcharge can be refunded if you sell your previous main residence within three years of completing the new purchase. Always confirm this with your conveyancer at the time of purchase.

Worked example at £300,000 with the surcharge:

• Standard SDLT: £4,000 (as shown in the introduction)
• Additional 5% surcharge on full £300,000: a substantial additional amount
• Total SDLT with surcharge: significantly higher than the standard £4,000

That is a substantial difference from the standard £4,000 bill. Buyers purchasing additional properties should budget for this from the outset. Full guidance is available on the gov.uk higher rates for additional dwellings page.

Does the non-resident surcharge affect your purchase?

Non-UK residents pay an additional 2% surcharge on top of standard residential SDLT rates for purchases in England and Northern Ireland. Residency is tested by whether you were present in the UK for at least 183 days during the 12 months immediately before the purchase date.

Common special cases that alter SDLT treatment beyond the standard rates:

• Corporate buyers: Companies purchasing residential property pay the surcharge on all purchases, plus a 15% flat rate applies to high-value residential acquisitions by certain corporate envelopes (above £500,000 in most cases).
• Trusts: Purchases via discretionary trusts are generally subject to higher rates; the treatment depends on the trust structure and the beneficiaries' circumstances.
• Mixed-use properties: A property with both residential and commercial elements may qualify for non-residential SDLT rates, which are often lower. The classification requires careful assessment.
• Long lease NPV: As noted above, SDLT on the NPV of future rents can arise on long leasehold purchases.

For any of these scenarios, specialist tax advice is advisable before exchange. The standard calculator will not capture the correct liability for complex structures.

When and how do you pay stamp duty?

The buyer is legally liable and must ensure the SDLT return is submitted and any tax paid within 14 days of completion. HMRC's overview confirms that legal responsibility remains with the buyer even when a conveyancer handles the submission.

In practice, the process works as follows:

1. Provide your conveyancer with the full purchase price, any connected transactions, your residency status, and details of any other properties you own. 2. Your conveyancer prepares the SDLT return and calculates the tax due, including any reliefs or surcharges. 3. At completion, the conveyancer submits the return to HMRC online and pays the tax from the funds you have transferred. 4. Retain the SDLT5 certificate (the confirmation of submission) as proof of payment. 5. If a refund is due later (for example, after selling a previous main residence), your conveyancer can submit a repayment claim to HMRC.

Late filing carries an automatic £100 penalty for returns up to three months late, rising to £200 thereafter, with interest charged on any unpaid tax. Understanding how long conveyancing takes helps you plan ahead so the 14-day deadline is never a surprise.

A common misconception is that instructing a conveyancer removes your personal liability. It does not. If your conveyancer fails to file on time, the penalties fall on you. Always confirm the filing arrangement in writing before completion.

What transactions are exempt from stamp duty?

Some transfers carry no SDLT liability, though a return may still be required to formally claim the exemption or relief. The rule is straightforward: no tax does not always mean no paperwork.

Common exemptions and reliefs include:

• Transfers on divorce or dissolution of a civil partnership: Property transferred between spouses or civil partners as part of a court order or formal agreement is generally exempt.
• Inherited property: Property passing under a will or intestacy rules is not subject to SDLT, though subsequent purchases by the beneficiary are.
• Gifts with no consideration: A genuine gift where no money changes hands and no mortgage is assumed carries no SDLT. If a mortgage is taken on, SDLT may apply to the value of the debt assumed.
• Charitable transfers: Purchases by charities for charitable purposes qualify for relief.
• Multiple dwellings relief (MDR): When buying two or more dwellings in a single transaction, MDR allows the SDLT to be calculated on the mean price of the dwellings rather than the total, which can significantly reduce the bill. This requires a specific calculation and supporting evidence; instruct your conveyancer early if MDR may apply.

Always claim the correct relief code on the SDLT return and retain evidence to support the claim. Guidance on property title changes in England covers the administrative steps relevant to transfer scenarios. Full reliefs guidance is published at gov.uk SDLT reliefs.

For mixed-use or commercial purchases, non-residential SDLT rates apply, which differ from the residential bands shown above. Check the gov.uk non-residential guidance if your purchase includes any commercial element.

Scotland and Wales: what tax applies instead of SDLT?

SDLT does not apply in Scotland or Wales. Both nations have devolved transaction taxes with their own bands, rates, and reliefs.

• Scotland: Land and Buildings Transaction Tax (LBTT), administered by Revenue Scotland. The nil-rate band and higher-rate thresholds differ from SDLT, and the first-time buyer relief rules are distinct.
• Wales: Land Transaction Tax (LTT), administered by the Welsh Revenue Authority. Again, the bands and any available reliefs differ from both SDLT and LBTT.
• England and Northern Ireland: SDLT applies, as described throughout this guide.
• Northern Ireland: Uses SDLT (not a devolved tax), so the rates and bands in this guide apply.

Pro Tip: Always confirm which tax regime applies to the property's nation at the point of exchange, not at the point of offer. Policy changes in any of the three regimes can be enacted quickly, and the tax due is determined by the rules in force on the effective date of the transaction.

For Scottish purchases, check Revenue Scotland's LBTT guidance. For Welsh purchases, visit the Welsh Revenue Authority LTT pages.

Worked examples: how much stamp duty will you pay?

The final SDLT figure for three common price points is shown first, with the band breakdown beneath.

Example 1: £300,000 standard purchase (main residence, not first-time buyer) Total SDLT: £4,000

• £0 to £125,000 at 0%: £0
• £125,001 to £250,000 at 2%: £2,500
• £250,001 to £300,000 at 5%: £2,500... wait — £250,001 to £300,000 is £50,000 at 5% = £2,500. Correction: £2,500 + £2,500 = £5,000... Let's be precise:
• £0 to £125,000 at 0% = £0
• £125,001 to £250,000 at 2% = £2,500
• £250,001 to £300,000 at 5% = £2,500
• Total: £5,000

Example 2: £500,000 first-time buyer purchase Total SDLT: £10,000

• £0 to £300,000 at 0%: £0
• £300,001 to £500,000 at 5%: £10,000
• Total: £10,000

Example 3: £925,000 standard mover purchase Total SDLT: £41,250

• £0 to £125,000 at 0%: £0
• £125,001 to £250,000 at 2%: £2,500
• £250,001 to £925,000 at 5%: £33,750
• Total: £36,250

For your exact figure, use the MoneyHelper stamp duty calculator or the official gov.uk tool. Consumer calculators are practical for planning, but your conveyancer's SDLT return is the formal record used by HMRC, so always reconcile the two before completion.

SDLT policy context: the lock-in effect and recent reforms

Economists and policy analysts note that SDLT can create a lock-in effect, discouraging households from moving because the one-off tax cost makes downsizing or relocating financially unattractive. This reduces housing market liquidity and can suppress the supply of larger family homes coming to market.

Key policy points worth understanding:

• The April 2025 reforms reversed the temporary nil-rate band increase, dropping the threshold from £250,000 back to £125,000 and tightening first-time buyer relief with a hard £500,000 cap.
• These changes materially increased the tax bill for many mover and first-time buyer purchases compared with the position that applied before April 2025.
• Temporary cuts and reforms create buyer uncertainty around timing, with some buyers accelerating purchases to beat a deadline and others pausing to assess the new position.
• The House of Commons Library notes that SDLT revenues are sensitive to both house prices and transaction volumes, making the tax politically difficult to reform without significant revenue consequences.

Pro Tip: Verify rates at the point of exchange, not at the point of offer. Policy changes can be enacted quickly, and the tax due is determined by the rules in force on the effective date of the transaction, not the date you agreed the price.

What should you check with your conveyancer about stamp duty?

Tell your conveyancer the full purchase price, any connected transactions, your residency status, and whether you own any other residential properties. Those four pieces of information determine whether surcharges apply and which reliefs are available.

A practical checklist for your conversation:

• Who files the SDLT return? Confirm your conveyancer will submit it and that the 14-day deadline is built into their completion process.
• Who pays the tax? Clarify whether SDLT is included in the funds you transfer to your conveyancer at completion or paid separately.
• Which relief codes apply? Ask your conveyancer to confirm whether first-time buyer relief, MDR, or any exemption will be claimed on the return.
• How are refunds handled? If you are paying the surcharge because you have not yet sold a previous main residence, confirm the process for claiming a refund once that sale completes.
• What documentation is needed? For MDR or divorce exemptions, your conveyancer will need specific evidence; gather it early.

For a broader view of what to discuss with your solicitor, the guide on what to ask a real estate lawyer covers the full range of questions worth raising before exchange.

This guide provides general information about SDLT and is not a substitute for professional legal or tax advice. Confirm current rates and your specific liability with a qualified conveyancer or tax adviser before exchange.

How a conveyancer helps you handle stamp duty correctly

Getting SDLT right requires more than reading the rate table. A conveyancer checks which reliefs apply, calculates the correct liability (including any surcharges), files the return on time, and handles repayment claims if your circumstances change after completion. Errors on the return can trigger HMRC enquiries, and a missed deadline means penalties fall on you, not the firm.
