If you’re buying a buy-to-let property in the UK, Stamp Duty Land Tax (or SDLT) is going to be one of your biggest upfront costs — and it’s significantly higher than what someone buying their main home would pay.
Since October 2024, anyone buying a second property (including buy-to-let investments) pays an extra 5% surcharge on top of the standard Stamp Duty rates. And if you’re a non-UK resident, there’s an additional 2% surcharge on top of that.
This means you could be paying anywhere from 5% to 19% of the property price in Stamp Duty alone — before you’ve even paid for solicitor fees, surveys, or your mortgage deposit.
This guide will break down exactly how Stamp Duty works for buy-to-let landlords, show you how much you’ll pay with real examples, and explain when you might be able to avoid or reclaim some of it.
What is Stamp Duty Land Tax (SDLT)?
Stamp Duty Land Tax (SDLT) is a tax you pay to HMRC when you buy property or land in England and Northern Ireland.
If you’re buying in Scotland, you pay Land and Buildings Transaction Tax (LBTT) instead. In Wales, it’s called Land Transaction Tax (LTT). The rates and thresholds are different, but the basic principle is the same.
For the rest of this guide, we’ll focus on SDLT in England and Northern Ireland — which is what most buy-to-let investors deal with.
How Stamp Duty Works for Buy-to-Let Properties
When you buy a buy-to-let property, you pay higher Stamp Duty rates than someone buying their main home.
This is called the additional property surcharge — and it’s an extra 5% on top of the standard rates.
Standard Stamp Duty rates vs buy-to-let rates
Here’s how the rates compare:
| Property price | Standard SDLT rate | Buy-to-let rate (with 5% surcharge) |
| Up to £250,000 | 0% | 5% |
| £250,001 – £925,000 | 5% | 10% |
| £925,001 – £1.5 million | 10% | 15% |
| Over £1.5 million | 12% | 17% |
Important: The surcharge applies to the entire purchase price, not just the portion over £250,000.
Why is Stamp Duty higher for buy-to-let?
The Government introduced the 5% surcharge in 2016 to:
- Cool down the buy-to-let market
- Make it easier for first-time buyers to compete
- Generate more tax revenue from property investors
The surcharge increased from 3% to 5% in October 2024, making buy-to-let property significantly more expensive to purchase.
How Much Stamp Duty Will You Pay? Real Examples
Let’s look at exactly how much Stamp Duty you’d pay on different property prices.
Example 1: £150,000 buy-to-let property
Purchase price: £150,000
Since the price is under £250,000, the entire amount is taxed at the buy-to-let rate of 5%.
Stamp Duty: £150,000 × 5% = £7,500
Example 2: £250,000 buy-to-let property
Purchase price: £250,000
Again, the entire amount is under the first threshold, so:
Stamp Duty: £250,000 × 5% = £12,500
Example 3: £300,000 buy-to-let property
Purchase price: £300,000
Now it gets a bit more complex because the price crosses the first threshold. Here’s how it’s calculated:
On the first £250,000: £250,000 × 5% = £12,500
On the remaining £50,000: £50,000 × 10% = £5,000
Total Stamp Duty: £12,500 + £5,000 = £17,500
That’s 5.83% of the purchase price.
Example 4: £500,000 buy-to-let property
Purchase price: £500,000
On the first £250,000: £250,000 × 5% = £12,500
On the next £250,000: £250,000 × 10% = £25,000
Total Stamp Duty: £12,500 + £25,000 = £37,500
That’s 7.5% of the purchase price.
Example 5: £1 million buy-to-let property
Purchase price: £1,000,000
On the first £250,000: £250,000 × 5% = £12,500
On the next £675,000: £675,000 × 10% = £67,500
On the remaining £75,000: £75,000 × 15% = £11,250
Total Stamp Duty: £12,500 + £67,500 + £11,250 = £91,250
That’s 9.125% of the purchase price.
Quick reference table: How much Stamp Duty you’ll pay
| Property price | Stamp Duty (buy-to-let) | % of price |
| £150,000 | £7,500 | 5% |
| £200,000 | £10,000 | 5% |
| £250,000 | £12,500 | 5% |
| £300,000 | £17,500 | 5.83% |
| £400,000 | £27,500 | 6.88% |
| £500,000 | £37,500 | 7.5% |
| £750,000 | £62,500 | 8.33% |
| £1,000,000 | £91,250 | 9.13% |

Do You Always Pay the 5% Surcharge?
Not always. There are a few situations where you might not have to pay the additional property surcharge.
1. If it’s your first (and only) property
If you’re buying your very first property and you’re planning to rent it out (rather than live in it), you don’t pay the surcharge — you pay the standard residential rates.
But — you also won’t qualify for first-time buyer relief, which means you’ll pay Stamp Duty from £125,001 onwards (not £300,000 like first-time buyers who live in their homes).
This is quite rare, but it can happen if you’re buying a rental property before you’ve bought your own home.
2. If the property costs less than £40,000
Properties worth less than £40,000 are exempt from Stamp Duty, including the surcharge.
This is very rare in the current market, but it can apply to things like parking spaces, garages, or very small plots of land.
3. If you’re replacing your main home
If you’re selling your current main home and buying a new one, you don’t pay the surcharge — even if you briefly own both properties at the same time.
But — you need to complete the sale of your old home within 36 months of buying the new one. If you don’t, you’ll have to pay the surcharge (and you can’t reclaim it).
4. If you inherit a property
If you inherit a property as part of an estate, you don’t pay Stamp Duty on it — you pay Inheritance Tax instead.
But — if you already own a property and you then buy another one (while you still own the inherited property), you’ll pay the surcharge on the new purchase.
5. Married couples and civil partners
If you’re married or in a civil partnership, HMRC treats you as one person for Stamp Duty purposes.
This means:
- If either of you owns a property, both of you pay the surcharge when you buy another property together
- You can’t avoid the surcharge by putting the new property in just one person’s name
Example:
You own your main home. Your spouse doesn’t own any property. You decide to buy a buy-to-let property together.
Even though your spouse doesn’t personally own a property, you’ll both pay the surcharge because you’re treated as one household.
Non-UK Residents Pay Even More
If you’re a non-UK resident buying a residential property in England or Northern Ireland, you pay an additional 2% surcharge on top of the buy-to-let rates.
This was introduced in April 2021 to regulate foreign investment in the UK property market.
What counts as a non-UK resident?
You’re considered a non-UK resident if you’ve spent fewer than 183 days in the UK in the 12 months before you buy the property.
How much extra do non-residents pay?
Let’s look at an example:
Property price: £500,000
Standard buy-to-let Stamp Duty: £37,500 (as calculated earlier)
Plus 2% non-resident surcharge: £500,000 × 2% = £10,000
Total Stamp Duty for non-resident: £37,500 + £10,000 = £47,500
That’s 9.5% of the purchase price.
Can you reclaim the non-resident surcharge?
Yes — if you become a UK resident within 2 years of buying the property, you can apply for a refund of the 2% surcharge.
You’ll need to prove you now meet the UK residency test (spending at least 183 days in the UK over a 12-month period).
When Do You Pay Stamp Duty?
You have 14 days from the date of completion (when you officially own the property) to:
- File a Stamp Duty Land Tax return with HMRC
- Pay the tax in full
If you miss this deadline, HMRC will charge you penalties and interest.
Most people don’t pay Stamp Duty themselves — your solicitor or conveyancer will handle the filing and payment on your behalf. They’ll usually take the money from your deposit or mortgage funds on completion day.
Can You Avoid Paying Stamp Duty?
Legally? Not really.
But there are a few strategies landlords use to reduce the amount they pay:
1. Buy properties under £250,000
The surcharge applies from £0 upwards, but the percentage you pay is lowest on cheaper properties (a flat 5% on anything under £250,000).
If you’re building a portfolio, buying two £200,000 properties costs less in Stamp Duty than buying one £400,000 property.
Two £200,000 properties: 2 × £10,000 = £20,000 in Stamp Duty
One £400,000 property: £27,500 in Stamp Duty
2. Spread purchases across tax years
If you’re buying multiple properties, spreading the purchases across different tax years won’t reduce the Stamp Duty you pay, but it can help with cash flow and budgeting.
3. Buy through a limited company
Buying property through a limited company doesn’t reduce the Stamp Duty you pay upfront — you still pay the same rates.
But — it can save you tax in the long run because:
- Mortgage interest is fully deductible from rental income (unlike for personal landlords)
- You pay Corporation Tax (19%) instead of Income Tax (20%, 40%, or 45%)
The downside is that transferring property from personal ownership into a company triggers both Stamp Duty and Capital Gains Tax, so this usually only makes sense if you’re buying new properties, not transferring existing ones.
4. Buy properties just below the thresholds
If you’re looking at a property priced just over a threshold (e.g., £925,001), try negotiating down to just below it (e.g., £925,000).
At £925,001:
On first £250,000: £250,000 × 5% = £12,500
On next £675,000: £675,000 × 10% = £67,500
On remaining £1: £1 × 15% = £0.15
Total: £80,000.15
At £925,000:
On first £250,000: £250,000 × 5% = £12,500
On remaining £675,000: £675,000 × 10% = £67,500
Total: £80,000
A £1 difference in price saves £0.15 in Stamp Duty — not a huge saving. But understanding the thresholds can help with negotiations.
Can You Get a Stamp Duty Refund?
In some cases, yes.
1. If you sell your old main home within 36 months
If you paid the 5% surcharge because you owned two properties at the time of purchase, but you then sell your old main home within 36 months, you can apply for a refund of the surcharge.
Example:
You own your main home. You buy a new home and move into it, but you haven’t sold your old home yet. You pay the surcharge on the new property.
18 months later, you sell your old home.
You can now reclaim the 5% surcharge you paid on the new property.
2. If you become a UK resident (for non-residents)
If you paid the 2% non-resident surcharge but you become a UK resident within 2 years, you can reclaim it.
How to claim a refund
You need to submit an amended Stamp Duty Land Tax return to HMRC. Your solicitor can help with this, or you can do it yourself through the HMRC website.
The refund usually takes 4–6 weeks to process.
Stamp Duty in Scotland and Wales
If you’re buying in Scotland or Wales, the system is slightly different.
Scotland: Land and Buildings Transaction Tax (LBTT)
Additional dwelling supplement: 6% (higher than England’s 5%)
LBTT rates for buy-to-let (2025/26):
| Property price | LBTT rate (including 6% supplement) |
| Up to £145,000 | 6% |
| £145,001 – £250,000 | 8% |
| £250,001 – £325,000 | 11% |
| £325,001 – £750,000 | 16% |
| Over £750,000 | 18% |
Wales: Land Transaction Tax (LTT)
Higher rate supplement: 5% (same as England)
LTT rates for buy-to-let (2025/26):
| Property price | LTT rate (including 5% supplement) |
| Up to £225,000 | 5% |
| £225,001 – £400,000 | 10% |
| £400,001 – £750,000 | 12.5% |
| £750,001 – £1.5 million | 15% |
| Over £1.5 million | 17% |
Is Buy-to-Let Still Worth It With Higher Stamp Duty?
That depends on your situation.
The 5% surcharge (up from 3% in 2024) has made buy-to-let more expensive to enter. But it hasn’t killed the market entirely.
When buy-to-let still makes sense
- You’re a higher-rate taxpayer and you’re buying through a limited company
- You’re buying in an area with strong rental demand and good capital growth
- You’re holding properties long-term (10+ years), so the upfront Stamp Duty is spread over many years of rental income
- You’re buying properties under £250,000, where the surcharge is a flat 5%
When it might not make sense
- You’re buying short-term (flipping properties in 1–2 years) — the Stamp Duty eats into your profit margin
- You’re a basic-rate taxpayer with a large mortgage — the combination of Stamp Duty and mortgage interest changes since 2020 can make returns very tight
- You’re buying in an area with weak rental yields — if you’re only getting 3–4% gross yield, the Stamp Duty can take years to recover
Common Stamp Duty Mistakes Landlords Make
1. Not budgeting for Stamp Duty upfront
Many new landlords focus on the deposit and forget that Stamp Duty is due within 14 days of completion.
On a £300,000 property, that’s £17,500 you need to have available immediately.
2. Assuming the surcharge doesn’t apply
Some landlords think “I’m selling my old home, so I won’t pay the surcharge.” But if you haven’t completed the sale by the time you buy the new property, you’ll pay the surcharge (though you can reclaim it later).
3. Not reclaiming the surcharge when eligible
If you sell your old main home within 36 months, you’re entitled to a refund — but HMRC won’t do it automatically. You have to apply.
Thousands of landlords miss out on refunds every year simply because they don’t know they’re entitled to them.
4. Mixing up residential and commercial Stamp Duty
If you’re buying a commercial property (like a shop with a flat above it), you pay commercial Stamp Duty rates, which are lower.
Some landlords pay residential rates by mistake and overpay.
Final Thoughts
Stamp Duty on buy-to-let properties is now one of the biggest upfront costs of property investment in the UK.
Here’s the short version:
- You pay 5% more than standard residential rates (the additional property surcharge)
- Non-UK residents pay an extra 2% on top of that
- On a £300,000 property, you’ll pay £17,500 in Stamp Duty
- On a £500,000 property, you’ll pay £37,500
- You have 14 days to file and pay after completion
- You can reclaim the surcharge in some situations (selling your old home within 36 months, or becoming a UK resident)
Before you buy, make sure you’ve factored Stamp Duty into your budget — because it’s a cost you can’t avoid, and it’s not getting any cheaper.
