Example Data Table
These examples show how different buyer types can change the SDLT estimate.
| Scenario | Price | Status | Non-resident | Estimated SDLT |
|---|---|---|---|---|
| Main residence | £250,000.00 | main | No | £2,500.00 |
| Main residence | £295,000.00 | main | No | £4,750.00 |
| First-time buyer | £425,000.00 | first time | No | £6,250.00 |
| Additional dwelling | £300,000.00 | additional | No | £20,000.00 |
| Non-resident buyer | £300,000.00 | main | Yes | £11,000.00 |
Formula Used
The calculator uses a sliced band method. Each part of the price is taxed only inside its band.
Band tax = taxable slice × applicable rate
Total SDLT = purchase SDLT + lease rent SDLT
Effective rate = total SDLT ÷ property price × 100
Current Residential Bands Used
| Price Slice | Standard Rate | Additional Dwelling | Non-resident Uplift |
|---|---|---|---|
| Up to £125,000 | 0% | +5% | +2% |
| £125,001 to £250,000 | 2% | +5% | +2% |
| £250,001 to £925,000 | 5% | +5% | +2% |
| £925,001 to £1,500,000 | 10% | +5% | +2% |
| Above £1,500,000 | 12% | +5% | +2% |
First-time buyer relief uses 0% up to £300,000 and 5% from £300,001 to £500,000. If the price is above £500,000, standard bands are used.
For new residential leasehold rent, this page estimates 1% on the NPV amount above £125,000. Non-resident uplift is added when selected.

England Stamp Duty Guide
Stamp duty can change the real cost of a home purchase. Buyers often focus on the deposit, mortgage fees, and moving costs. Yet SDLT can add a large amount at completion. This calculator helps you estimate that figure before you commit. It uses tiered bands, so only the slice inside each band is taxed at that band rate. This is why a small price increase can create a smaller tax jump than many people expect.
Why SDLT Matters
England uses Stamp Duty Land Tax for residential property purchases. The rules are different in Scotland and Wales. A main home buyer usually pays the standard residential rates. A first time buyer may receive relief when the price qualifies. A buyer of an additional dwelling usually pays a surcharge. Non resident buyers may also face another surcharge. These choices can produce very different totals for the same property price.
Planning Your Purchase
Use the calculator during early research, mortgage planning, and offer checks. Enter the agreed price or expected price. Then choose the correct buyer status. Add non resident status when it applies. For new leasehold purchases, add the rent net present value if you have it. The result shows total tax, effective rate, and each taxed slice. This makes the estimate easier to review with a solicitor or adviser.
Useful Buying Tips
Always confirm your final position before completion. Reliefs can depend on ownership history, residence plans, company status, linked purchases, and replacement rules. A replacement main residence may avoid the higher rate when conditions are met. Some transactions need special treatment. Shared ownership, companies, trusts, six or more dwellings, mixed property, and complex leases can require detailed checks.
Better Cost Control
A clear stamp duty estimate improves budgeting. It can help you compare two homes, test a larger deposit, or decide whether a higher offer remains affordable. Keep a copy of your result. Use the CSV and PDF buttons to save your assumptions. Update the calculation when the price, buyer status, or lease details change.
The goal is not legal advice. It is a practical planning tool for cleaner estimates and faster property comparisons during searches.
