Stamp Duty Calculator Manual

Overview

The Stamp Duty Calculator helps property investors and homebuyers estimate stamp duty liability on UK property purchases. It covers all four jurisdictions — SDLT (England and Northern Ireland), LBTT (Scotland), and LTT (Wales) — with support for residential, non-residential, and mixed-use properties, individual and corporate buyers, surcharges, and first-time buyer relief.

For the calculation methodology behind this tool, see the Stamp Duty Methodology page. To use the calculator directly, go to the Stamp Duty Calculator.

Getting Started

Step 1 — Select Your Jurisdiction

Choose the jurisdiction where the property is located:

• England (SDLT) — HMRC rates and rules
• Scotland (LBTT) — Revenue Scotland rates and rules
• Wales (LTT) — Welsh Revenue Authority rates and rules
• Northern Ireland (SDLT) — Same SDLT rates as England

Step 2 — Enter the Purchase Price

Enter the property purchase price in pounds. The calculator accepts values from £0 to £50,000,000.

Step 3 — Select Buyer Type

• Individual — Personal purchase (includes first-time buyer relief eligibility)
• Limited Company — Corporate purchase (triggers corporate rate rules in England/NI)

Step 4 — Select Property Type

• Residential — Standard residential property (surcharges and reliefs apply)
• Non-residential — Commercial property or land (different rate bands)
• Mixed-use — Property with both residential and non-residential elements

Step 5 — Set Buyer Flags

• First-time buyer — Tick if you're a first-time buyer (individuals only). Triggers relief bands.
• Owns other property — Tick if you already own another property. Triggers additional property surcharges.
• Non-UK resident — Tick if you're not a UK resident. Triggers 2% surcharge (England/NI only).

Common Scenarios

Standard Individual Purchase (England)

A UK-resident individual buying a second residential property for £400,000:

• Base tax: £10,000 (progressive bands)
• HRAD surcharge: £12,000 (3% on £400,000)
• Total: £22,000 (effective rate 5.50%)

Corporate Purchase (England)

A limited company buying a residential property for £600,000:

• Flat 17% rate (price ≥ £500,000)
• No HRAD surcharge (corporate buyers excluded)
• Total: £102,000 (effective rate 17.00%)

First-Time Buyer (England)

A first-time buyer purchasing a £400,000 residential property:

• FTB bands: 0% up to £300,000, 5% on £300,001–£500,000
• Tax: £5,000 (5% on £100,000)
• Relief amount: £5,000 (standard tax £10,000 minus FTB tax £5,000)

Tips for Accurate Results

1. Check your jurisdiction — Rates differ significantly between England, Scotland, Wales, and Northern Ireland.
2. Corporate buyers — In England/NI, corporate purchases at or above £500,000 use a flat 17% rate. Below £500,000, progressive higher rates apply.
3. Wales additional properties — Wales uses an alternate rate table (not a flat surcharge). The entire rate structure changes.
4. Surcharges can stack — In England/NI, a non-UK resident who owns another property pays both HRAD (+3%) and non-UK resident (+2%) = +5% on top of base rates.
5. First-time buyer threshold — In England/NI, relief is lost entirely if the price exceeds £500,000. Even £1 over means standard rates apply to the full price.

Limitations

This calculator does not cover:

FAQ

Why does my SDLT differ from HMRC's calculator?

Small differences can arise from rounding — this calculator rounds per band to the nearest penny. For corporate purchases, the flat 17% rate applies at and above £500,000. If your result differs significantly, check your jurisdiction, buyer type, and property type selections.

Does this calculator cover Scotland and Wales?

Yes. The calculator supports LBTT (Scotland) and LTT (Wales) with jurisdiction-specific rate bands, surcharges, and first-time buyer relief where applicable. Wales does not offer first-time buyer relief. Scotland applies an 8% Additional Dwelling Supplement (ADS) on the full purchase price for additional properties.

How does the calculator handle corporate purchases?

In England and Northern Ireland, corporate buyers of residential property pay either progressive higher rates (below £500,000) or a flat 17% rate (at or above £500,000). Corporate buyers do not pay the 3% HRAD surcharge. For non-residential properties, corporate buyers pay standard non-residential rates. Scotland and Wales have no special corporate rules.

Can surcharges stack?

Yes. In England and Northern Ireland, a non-UK resident who owns another property can be subject to both the 3% HRAD surcharge and the 2% non-UK resident surcharge — a combined +5% on top of base rates.
