How Much SDLT Do You Pay on a Second Property in the UK?
Buying a second property costs significantly more than most buyers anticipate — not because of a higher purchase price, but because of a stamp duty bill that catches people off-guard every single time.
On a £300,000 second property, you will pay approximately £17,500 in Stamp Duty Land Tax. On a £500,000 purchase, the bill reaches £40,000. These are not marginal costs — they represent 5–8% of the purchase price in cash that must be available on completion day, above and beyond your deposit.
The rules changed twice in quick succession. In October 2024, the additional dwelling surcharge rose from 3% to 5%. In April 2025, the nil-rate threshold reverted from £250,000 to £125,000 following the expiry of the pandemic-era stamp duty holiday extension. Both changes increased the tax burden on second-property buyers materially.
This guide covers the current rates with worked examples at £200k, £350k, and £500k; the Scotland and Wales rules; every exemption and relief available; and the definitive side-by-side comparison of buying in personal name versus through a limited company SPV — including the critical £500,000 cliff edge that costs investors tens of thousands if they have not planned for it.

What is SDLT and when does the second property surcharge apply?
Stamp Duty Land Tax is a transaction tax charged on the purchase of land and property in England and Northern Ireland (Scotland and Wales have their own equivalents). It is payable on completion and calculated as a percentage of the purchase price in bands — not a flat rate on the whole amount.
The additional dwelling surcharge applies when you purchase a residential property and, at the end of the completion day, you own two or more residential properties. The second property does not need to be in England — if you own a property anywhere in the world and you buy a second property in England, the surcharge applies.
The £40,000 threshold
The surcharge only applies to purchases where the value of the additional dwelling is at least £40,000. Below that threshold, you pay standard SDLT rates (currently zero on properties up to £125,000 under the standard residential bands).
What counts as a "second property"?
The rules here are broader than many buyers expect.
Worldwide rule: Property ownership outside England and Northern Ireland counts. A holiday flat in Spain, a buy-to-let in Scotland, inherited property in Ireland — all count toward the "second property" threshold.
Joint ownership: If you purchase jointly with another person and either of you owns another residential property, the surcharge applies to the entire purchase. The fact that your partner does not own another property does not help if you do.
Inherited property: In most circumstances, inherited property counts. There is a limited 36-month grace period if you inherit your late spouse or civil partner's share of a jointly-owned property, but general inheritance of a property that you retain triggers second-property status.
Current SDLT rates for second properties in England (2025/26)
The following rates apply to purchases of additional residential dwellings in England and Northern Ireland, effective 1 April 2025.
| Property value band | Standard rate | Additional dwelling rate (standard + 5%) |
|---|---|---|
| Up to £125,000 | 0% | 5% |
| £125,001 – £250,000 | 2% | 7% |
| £250,001 – £925,000 | 5% | 10% |
| £925,001 – £1.5 million | 10% | 15% |
| Over £1.5 million | 12% | 17% |
Source: GOV.UK — effective 1 April 2025
The rates are applied in bands to the relevant portion of the purchase price — not as a flat rate on the full amount. This is the same marginal band system as income tax.
Worked example — £200,000 second property
| Band | Amount | Rate | SDLT |
|---|---|---|---|
| Up to £125,000 | £125,000 | 5% | £6,250 |
| £125,001–£200,000 | £75,000 | 7% | £5,250 |
| Total | £11,500 |
For comparison: a first-time buyer purchasing the same property would pay £1,500 in SDLT (0% on first £425,000 under first-time buyer relief). An owner-occupier buying their only home would pay £1,500 at standard rates.
Worked example — £350,000 second property
| Band | Amount | Rate | SDLT |
|---|---|---|---|
| Up to £125,000 | £125,000 | 5% | £6,250 |
| £125,001–£250,000 | £125,000 | 7% | £8,750 |
| £250,001–£350,000 | £100,000 | 10% | £10,000 |
| Total | £25,000 |
Worked example — £500,000 second property
| Band | Amount | Rate | SDLT |
|---|---|---|---|
| Up to £125,000 | £125,000 | 5% | £6,250 |
| £125,001–£250,000 | £125,000 | 7% | £8,750 |
| £250,001–£500,000 | £250,000 | 10% | £25,000 |
| Total | £40,000 |

Scotland and Wales — different rules
Scotland and Wales have devolved responsibility for property transaction taxes and operate their own separate regimes.
Scotland — Land and Buildings Transaction Tax (LBTT): An additional dwellings supplement (ADS) applies at 6% on the entire purchase price of additional residential properties worth £40,000 or more, on top of standard LBTT rates. The ADS rate was increased from 4% to 6% in December 2024.
Wales — Land Transaction Tax (LTT): Higher rates apply to additional residential properties in Wales from a £40,000 threshold. The minimum additional dwelling rate in Wales starts at 5%.
If your purchase is in Scotland or Wales, do not use the England/Northern Ireland rates above. Refer to Revenue Scotland (revenue.scot) and the Welsh Revenue Authority (gov.wales/wra) for current rates.
Exemptions and reliefs — can you avoid the surcharge?
Replacing your main residence
The most common situation where the surcharge does not apply: you are replacing your main residence. If you sell your previous main home and buy a new one in the same transaction, or if you buy a new main home before selling the old one but sell the old one within 36 months of completion, you do not pay the surcharge — or you can claim it back.
The completion day rule: On the day you complete the new purchase, do you own two or more properties? If yes — even if you have exchanged on the sale of your previous home — you will pay the higher rate. The refund mechanism then kicks in: if you sell your previous main home within 36 months of completing the new purchase, you can claim a refund of the surcharge from HMRC.
How to claim the refund: Via Government Gateway (gov.uk/guidance/claim-a-refund-of-sdlt). You have 12 months from the date of the sale of the previous property to make the claim, or 12 months from the filing date for the SDLT return, whichever is later.
Properties under £40,000
The additional dwelling surcharge only applies where the additional property is valued at £40,000 or more. Purchases below this threshold are charged at standard SDLT rates.
Inherited property — grace period
Where you inherit a property and then buy a new residential property, the inherited property counts for second-property purposes. However, a 36-month grace period applies if you inherit a share of a property from a deceased spouse or civil partner. Speak to a specialist conveyancer before making assumptions about inherited property and SDLT.
Divorce and civil partnership dissolution
Properties transferred between spouses as part of a divorce settlement can in some circumstances benefit from relief from SDLT — but the rules are complex and depend on the specific structure of the transaction. Tax advice before the financial settlement is finalised is essential.
Should you buy in personal name or a limited company? (The SPV comparison)
This is the question most serious BTL investors are asking in 2026, and the answer on SDLT is simpler than many people assume — it is the wrong question.
Many investors assume buying through a limited company (SPV) saves SDLT. Below £500,000, it does not. The SDLT payable by a company purchasing an additional residential dwelling is identical to the amount payable by an individual on the same price. The SPV decision is about income tax, not stamp duty.

What is an SPV and how does its SDLT work?
A Special Purpose Vehicle (SPV) is a limited company registered specifically to hold investment property. The standard SIC code for UK property holding companies is 68100. Setting one up costs from £12 at Companies House; the ongoing costs (accountancy, Companies House annual return, business banking) run to approximately £873–£2,493 per year.
For properties under £500,000, the SDLT calculation for an SPV purchase follows exactly the same banded structure as a personal purchase, including the 5% additional dwelling surcharge. The company is treated as an entity that already owns (or will own) additional property, so the standard additional dwelling rates apply.
For properties over £500,000, a flat 17% rate applies on the entire purchase price — not just the portion above £500,000. This is the corporate rate for residential property purchases, and it produces dramatically higher SDLT bills than the personal banded calculation.
SDLT comparison table — personal name vs SPV
| Purchase price | SDLT (personal name) | SDLT (SPV / Ltd company) | Difference |
|---|---|---|---|
| £200,000 | £11,500 | £11,500 | £0 |
| £350,000 | £25,000 | £25,000 | £0 |
| £500,000 | £40,000 | £40,000 | £0 |
| £600,000 | ~£48,750 | £102,000 (17% flat) | +£53,250 |
| £1,000,000 | ~£73,750 | £170,000 (17% flat) | +£96,250 |
The key insight: below £500,000, SDLT is identical in personal name and SPV. The SPV decision is driven by income tax, not stamp duty.
Why investors still choose an SPV despite identical SDLT
The income tax case for SPV ownership has become compelling for higher-rate taxpayers since April 2020:
Section 24 restrictions: Personal-name landlords receive only a 20% basic-rate tax credit on mortgage interest, regardless of their tax rate. A 40% taxpayer paying £10,000/year in mortgage interest gets a £2,000 tax credit — not £4,000. The effective cost of the mortgage is higher after tax than in an SPV.
SPV tax treatment: A limited company holding buy-to-let property can deduct mortgage interest in full as a business expense before calculating taxable profit. Corporation tax (19–25%) then applies to the remaining profit, rather than income tax at 40–45%.
Inheritance planning: Shares in an SPV can be transferred gradually to beneficiaries without triggering the same CGT and SDLT consequences as gifting property directly.
For a landlord with three properties generating £40,000 net rental income and £20,000 mortgage interest costs, the personal-name vs SPV difference in annual tax liability can reach £4,000–£8,000 per year.
The £500,000 cliff edge — a critical warning
The single most expensive mistake in BTL structuring: buying a property over £500,000 through an SPV without taking specialist SDLT advice first.
A £600,000 property purchased through a limited company attracts SDLT of £102,000 — 17% of the entire purchase price. The same property purchased in personal name costs approximately £48,750 in SDLT. The difference is £53,250 — more than the annual rental income on most BTL properties.
This is not a loophole. It is a known structural penalty that applies above the £500,000 threshold. Investors who are unaware of it, or who assume company SDLT mirrors personal SDLT at all price points, face a bill they did not budget for.

Annual costs and ongoing considerations for SPVs
Buying through an SPV is not free even after the formation cost:
- Accountancy: £500–£1,500/year for a property-holding SPV with standard reporting requirements
- Companies House annual return: £13/year
- Business bank account: approximately £120/year
- ATED (Annual Tax on Enveloped Dwellings): Applies to companies owning single residential properties worth over £500,000. Charges range from £4,400/year (£500k–£1m) to over £260,000/year (over £20m). Specific reliefs apply to genuine let residential property — this is a complex area requiring specialist advice
When does an SPV make sense?
Broadly beneficial when:
- Higher-rate taxpayer (40%+ income tax)
- Planning to hold the property for 5+ years
- Building a portfolio of 4+ properties
- Wants to plan inheritance via share transfer
Broadly not beneficial when:
- Basic-rate taxpayer with a single property
- Short-term hold or likely to sell within 3–5 years
- The SPV mortgage rate premium and annual accountancy costs exceed the annual tax saving

SDLT refunds — claiming back the surcharge
The most commonly missed refund opportunity: buying a new main residence before selling the previous one.
If you paid the higher rate of SDLT on a new main home because you still owned your previous property at completion, and you sell the previous property within 36 months, you can reclaim the additional 5% surcharge from HMRC.
Step-by-step:
1. Confirm you sold the previous main home within 36 months of completing the new purchase
2. Calculate the refund due (5% of the purchase price, applied in bands)
3. Log into Government Gateway and access the SDLT repayment section, or instruct your solicitor to file on your behalf
4. Submit within 12 months of the sale of the previous property (or 12 months from the SDLT filing date, whichever is later)
The refund claim is straightforward for standard main-home replacement cases. For complex situations — inherited properties, mixed-use properties, properties held in trust, or disputed "main residence" status — specialist SDLT advice is worth the cost.

Do you need professional SDLT advice?
For a standard second property purchase under £500,000, your solicitor can handle the SDLT calculation and filing as part of the conveyancing process. The calculation is mechanical once the facts are established.
Professional SDLT advice becomes genuinely valuable in the following situations:
- Property over £500,000 in a limited company — the 17% flat-rate penalty can be structured around in some circumstances
- Complex ownership structures — joint ownership, trusts, bare trusts, life interest trusts
- Non-UK resident purchasers — the 2% non-resident surcharge applies on top of all other rates; effective maximum rate for a non-resident buying a second home over £1.5m through an SPV is 19%
- Multiple Dwellings Relief — abolished in June 2024, but historic overpayment claims for transactions completed before that date remain possible
- Disputed main residence status — where it is not clear which property HMRC would regard as your main home
- Properties previously purchased with incorrect SDLT treatment — HMRC has a 4-year window to investigate, and so do you to claim overpayments
What SDLT specialists do that a standard conveyancer does not: review the whole transaction for reliefs and exemptions, not just calculate the standard liability. Specialist advisers routinely identify reliefs that the buyer's solicitor did not apply, particularly on mixed-use properties, uninhabitable dwellings, and properties with commercial elements.
SDLT is one of the largest upfront costs in any property transaction. A consultation with Cornerstone Tax can identify reliefs, refund opportunities, and optimal ownership structures — potentially saving thousands.

Frequently asked questions
Do I pay stamp duty on a second property if I sell my first?
If you complete on the sale of your previous main home on or before the completion date of the new purchase, the surcharge does not apply. If you buy before you sell, you pay the surcharge on completion and can reclaim it within 12 months of selling the previous property, provided the sale happens within 36 months.
Can I avoid the SDLT surcharge by buying in joint names?
Only if neither person purchasing already owns a residential property. If one joint buyer owns another property, the surcharge applies to the entire transaction — it is not applied only to the share owned by the person with existing property.
Is the 5% surcharge the same for buy-to-let and second homes?
Yes. SDLT does not distinguish between a BTL investment and a second home for personal use. Both attract the additional dwelling surcharge at 5% across the applicable bands.
Does an inherited property count as a second property for SDLT?
In most cases, yes. Inheriting a property makes you a property owner, which counts towards the additional dwelling threshold. Limited exceptions apply for spousal inheritance. Take tax advice before completing any property purchase if you have recently inherited.
Can a limited company claim first-time buyer relief?
No. First-time buyer relief applies only to individual purchasers, not companies. A company has no "first-time buyer" status regardless of whether it has previously purchased property.
What happens if I miss the 36-month refund deadline?
HMRC will not grant the refund after the 36-month window to sell the previous property has passed, or after the 12-month claim window from the filing date. There are no routinely applied extensions. If you are approaching either deadline, act immediately.
Conclusion
The SDLT position on second properties in 2025/26 is straightforward below £500,000: you pay the standard additional dwelling rates, the 5% surcharge applies from £40,000, and the bill is the same whether you buy in personal name or through an SPV.
The critical decision points are: whether you have recently sold a previous main home and are entitled to a surcharge refund; whether your property is near or above £500,000 (where the corporate flat rate is a material penalty); and whether you have paid SDLT correctly on past transactions.
For most BTL investors buying standard residential property under £500,000, the SPV decision rests on income tax — not stamp duty. For higher-rate taxpayers planning to hold for the medium to long term, the income tax case for SPV ownership is now compelling.
