Stamp Duty for Landlords: Additional Rate Explained

The Additional Rate Surcharge

When purchasing a buy-to-let or additional residential property in England and Northern Ireland, you pay the standard Stamp Duty Land Tax (SDLT) rates plus an additional 5% surcharge (increased from 3% in October 2024).

This applies if you already own a residential property and are buying another one. It does not apply to your first property purchase.

SDLT Rates for Additional Properties (2025/26)

| Property Price Band | Standard Rate | Additional Rate (incl. surcharge) | |--------------------|--------------|---------------------------------| | Up to £250,000 | 0% | 5% | | £250,001 to £925,000 | 5% | 10% | | £925,001 to £1,500,000 | 10% | 15% | | Above £1,500,000 | 12% | 17% |

Worked Examples

£200,000 Buy-to-Let

• £200,000 at 5%: £10,000
• Total SDLT: £10,000

Compare to first-time buyer: £0 (below the first-time buyer threshold)

£350,000 Buy-to-Let

• First £250,000 at 5%: £12,500
• Next £100,000 at 10%: £10,000
• Total SDLT: £22,500

£500,000 Buy-to-Let

• First £250,000 at 5%: £12,500
• Next £250,000 at 10%: £25,000
• Total SDLT: £37,500

When the Surcharge Applies

The surcharge applies when:

• You own (or partly own) another residential property anywhere in the world
• You are purchasing an additional residential property in England or Northern Ireland
• The property costs more than £40,000

Exceptions

• Replacing your main residence — if you sell your old home within 36 months of buying the new one, you can reclaim the surcharge
• Properties under £40,000 — the surcharge does not apply
• Caravans, mobile homes, and houseboats — not subject to the surcharge

Impact on Buy-to-Let Economics

The 5% surcharge significantly affects the return on investment for buy-to-let properties. On a £300,000 property, the surcharge adds £15,000 to your purchase costs. This must be funded upfront and cannot be reclaimed through rental income tax deductions.

When calculating the viability of a buy-to-let investment, include the full SDLT (with surcharge) in your upfront costs and factor it into your yield calculation.

Scotland and Wales

Scotland and Wales have their own property transaction taxes:

• Scotland: Land and Buildings Transaction Tax (LBTT) with a 6% Additional Dwelling Supplement
• Wales: Land Transaction Tax (LTT) with a 4% higher rate

The rates and thresholds differ from SDLT, so check the specific rules for the relevant jurisdiction.
