UK Stamp Duty Rates

Stamp duty rates vary depending on the property value and your status as a first-time buyer. Here are the current rates as of 2023:

Residential Property Rates

Purchase Price	First-time Buyer Rate	Standard Rate
£0 - £300,000	0%	0%
£300,001 - £500,000	5%	5%
£500,001 - £925,000	10%	10%
£925,001 - £1.5M	15%	15%
Over £1.5M	12% on amount over £1.5M	12% on amount over £1.5M

First-time buyers get a 3-year stamp duty holiday on properties under £500,000, meaning they pay no stamp duty on purchases under £425,000.

Commercial Property Rates

Commercial property stamp duty rates are higher and vary by property type:

Offices: 10% on the first £150,000, then 5% on the remainder
Retail: 10% on the first £150,000, then 5% on the remainder
Industrial: 10% on the first £150,000, then 5% on the remainder
Land: 2% on the first £150,000, then 5% on the remainder

How Stamp Duty is Calculated

The stamp duty calculation follows these steps:

Determine the property value
Check if you qualify for any reliefs (first-time buyer, etc.)
Apply the appropriate rate to the relevant portion of the property value
Sum the amounts from each rate bracket

Calculation Formula

For residential properties:

Stamp Duty = Σ (Rate × (Upper Bracket - Lower Bracket))
Where:
- Rate is the applicable percentage for each bracket
- Upper Bracket is the upper limit of the bracket
- Lower Bracket is the lower limit of the bracket

For example, a £600,000 property would be calculated as:

First £300,000: £0 (exempt)
Next £200,000 (£300,001-£500,000): £10,000 (5%)
Next £100,000 (£500,001-£600,000): £10,000 (10%)
Total: £20,000

Worked Examples

Example 1: First-time Buyer

Purchase price: £450,000

Calculation:

First £300,000: £0 (exempt)
Next £150,000 (£300,001-£450,000): £7,500 (5%)
Total stamp duty: £7,500

Example 2: Standard Rate Buyer

Purchase price: £750,000

Calculation:

First £300,000: £0 (exempt)
Next £200,000 (£300,001-£500,000): £10,000 (5%)
Next £250,000 (£500,001-£750,000): £25,000 (10%)
Total stamp duty: £35,000

Frequently Asked Questions

Stamp duty is typically paid when you complete the purchase of the property, usually at the same time as paying the purchase price.

Can I pay stamp duty in installments?

Yes, you can pay stamp duty in installments if you're buying with a mortgage. The lender will usually deduct the duty from your mortgage payments.

Is stamp duty the same for all properties?

No, stamp duty rates vary by property type and buyer status. Residential properties have different rates than commercial properties, and first-time buyers get special rates.

Can I get a refund on stamp duty?
