Buy-to-Let Stamp Duty Rates 2026
Buy-to-let investors pay higher Stamp Duty Land Tax (SDLT) than residential buyers. Since April 2016, purchasing an additional property in England attracts a 3% surcharge on top of the standard SDLT rates. This guide covers the current rates, worked examples, and how stamp duty affects your rental yield.
Current BTL Stamp Duty Rates (2026)
When buying a buy-to-let or second home in England, you pay the standard SDLT rate plus 3% on each band:
| Purchase Price Band | Standard Rate | BTL Rate (+3%) |
|---|---|---|
| Up to £125,000 | 0% | 3% |
| £125,001 – £250,000 | 2% | 5% |
| £250,001 – £925,000 | 5% | 8% |
| £925,001 – £1,500,000 | 10% | 13% |
| Above £1,500,000 | 12% | 15% |
SDLT is a progressive tax — you only pay the higher rate on the portion of the price within each band, not on the entire purchase price.

How Stamp Duty Affects Rental Yield
Stamp duty is a one-off upfront cost that reduces your overall return on investment. While it does not change your annual gross yield calculation, it is a significant part of your total acquisition cost.
To understand the true impact, consider stamp duty as part of your total investment:
Yield on Total Cost = (Annual Rent) ÷ (Purchase Price + Stamp Duty + Legal Fees) × 100
For a £250,000 buy-to-let property with £850/month rent:
- Gross yield (on purchase price): (£850 × 12) ÷ £250,000 = 4.08%
- Yield on total cost: (£850 × 12) ÷ (£250,000 + £10,000 + £2,000) = 3.89%
The higher the property price, the more stamp duty erodes your effective yield. This is one reason why lower-value properties in Northern England often deliver better returns — stamp duty is a smaller proportion of the total investment.
When the Surcharge Does Not Apply
The 3% surcharge does not apply if:
- You are buying your only property (your main residence)
- You are replacing your main residence (you sell within 3 years)
- The property costs less than £40,000
- You are a first-time buyer purchasing your first home (separate first-time buyer relief applies)
The surcharge does apply if you already own a property and are buying an additional one, regardless of whether it is for buy-to-let or personal use.
Companies and Stamp Duty
If you purchase through a limited company, the 3% surcharge always applies — even if it is the company's first property. Properties above £500,000 purchased by companies may also be subject to the 15% flat rate under the Annual Tax on Enveloped Dwellings (ATED) regime, though buy-to-let properties are generally exempt from ATED.

You can also browse rental yields by postcode to find areas where lower property prices mean lower stamp duty and higher yields.
Key Points for BTL Investors
- Budget for stamp duty as a significant upfront cost — it ranges from 3% on low-value properties to over 6% on properties above £500,000
- Stamp duty cannot be offset against rental income for tax purposes
- Factor stamp duty into your total return calculation, not just your annual yield
- Lower-priced properties incur proportionally less stamp duty, improving total returns
