1. What is Commercial Stamp Duty?
Stamp duty (also called Stamp Duty Land Tax (SDLT) in the UK or Transfer Duty in some countries) is a government tax applied to property transactions. It’s typically paid by the buyer or tenant and varies based on:
- Property value
- Type of transaction (purchase, lease, transfer)
- Location (different rates apply in different states/countries)
Who Pays Commercial Stamp Duty?
- Buyers – When purchasing commercial property
- Tenants – When signing a lease (especially long-term leases with high rent)
- Investors – When transferring ownership or acquiring shares in a property-holding company
💡 Pro Tip: Some jurisdictions offer stamp duty exemptions or concessions for first-time buyers, small businesses, or specific industries. Always check local regulations!
2. How Commercial Stamp Duty is Calculated (By Country)
Stamp duty rates vary widely across countries. Below, we break down the key calculation methods in major markets.
A. United Kingdom (UK) – England & Northern Ireland
Tax Name: Stamp Duty Land Tax (SDLT)
Commercial Property Purchase Rates
| Property Value | Rate |
|---|---|
| Up to £150,000 | 0% |
| £150,001 – £250,000 | 2% |
| Above £250,000 | 5% |
Example:
- A £500,000 office purchase:
- £0 on first £150K
- 2% on next £100K = £2,000
- 5% on remaining £250K = £12,500
- Total SDLT = £14,500
Lease Duty (UK)
- Premium Duty: Same as purchase rates
- Rent Duty: 1% on Net Present Value (NPV) of rent over £150K

B. Australia (State-Based Stamp Duty)
Each Australian state has different rates. Here’s an approximate guide:
| State | Approx. Rate (for $1M property) |
|---|---|
| New South Wales (NSW) | ~4.5% ($45,000) |
| Victoria (VIC) | ~5.5% ($55,000) |
| Queensland (QLD) | ~3.5% ($35,000) |
| Western Australia (WA) | ~4.2% ($42,000) |

C. Singapore (Buyer’s Stamp Duty – BSD)
- 1% on first S$180K
- 2% on next S$180K
- 3% on remaining amount
Example (S$1M property):
- 1% of S$180K = S$1,800
- 2% of S$180K = S$3,600
- 3% of S$640K = S$19,200
- Total BSD = S$24,600
📌 Additional Buyer’s Stamp Duty (ABSD) may apply for foreign buyers.
D. Hong Kong
- Flat rate of 0.1% to 4.25% (scales with property value)
- Special Stamp Duty (SSD) if sold within 3 years
E. India (State-Based Stamp Duty)
- Typically 5%–8% of property value
- Maharashtra: 5%
- Delhi: 6%
- Karnataka: 5.6%
💡 Tip: Some Indian states allow e-stamping to avoid fraud.
