## What is Stamp Duty Land Tax (SDLT)?
Stamp Duty Land Tax (SDLT) is a tax paid when purchasing property or land in England and Northern Ireland. It is a tiered tax - like income tax - meaning you only pay each rate on the portion of the purchase price falling within that band, not on the full price.
SDLT must be paid within 14 days of completion. Your conveyancing solicitor will typically calculate and submit it as part of the purchase process. Late payment incurs interest plus HMRC penalties.
Scotland uses Land and Buildings Transaction Tax (LBTT) - different rates and thresholds apply.
Wales uses Land Transaction Tax (LTT) - again different from England.
## SDLT Bands for 2026 - Standard Residential Purchases
| Property Price Band | SDLT Rate |
|-------------------|-----------|
| Up to £250,000 | 0% |
| £250,001 - £925,000 | 5% |
| £925,001 - £1,500,000 | 10% |
| Above £1,500,000 | 12% |
Example - £400,000 standard purchase:
- 0% on first £250,000 = £0
- 5% on remaining £150,000 = £7,500
- Total SDLT: £7,500 (effective rate: 1.875%)
## First-Time Buyer Relief - 2026
First-time buyers in England pay reduced SDLT under relief rules:
| Property Price Band | First-Time Buyer Rate |
|-------------------|-----------------------|
| Up to £425,000 | 0% |
| £425,001 - £625,000 | 5% (on portion above £425k) |
| Above £625,000 | Standard rates apply (no relief) |
Both buyers must be genuine first-time buyers on joint purchases to qualify.
Example - £500,000 first-time buyer purchase:
- 0% on first £425,000 = £0
- 5% on remaining £75,000 = £3,750
- Total SDLT: £3,750 (vs £12,500 standard - saving of £8,750)
Example - £700,000 first-time buyer purchase (above relief threshold):
- Standard rates apply: 0% × £250k + 5% × £450k = £22,500
- No first-time buyer relief above £625,000
## Additional Dwelling Surcharge - Buy-to-Let and Second Homes
Buyers purchasing an additional residential property pay a 3% surcharge on all SDLT bands from £1. This applies to:
- Buy-to-let investments
- Holiday homes and second residences
- Purchases where you own another residential property and are not replacing your main residence
| Band | Standard Rate | Additional Property Rate |
|------|--------------|-------------------------|
| £0 - £250,000 | 0% | 3% |
| £250,001 - £925,000 | 5% | 8% |
| £925,001 - £1,500,000 | 10% | 13% |
| Above £1,500,000 | 12% | 15% |
Example - £300,000 buy-to-let property:
- Standard SDLT: 0% × £250k + 5% × £50k = £2,500
- Additional 3% on full £300k = £9,000
- Total SDLT: £11,500 (effective rate: 3.83%)
## SDLT Refund for Chain Movers
If you are buying a new primary residence before selling your existing home, you pay the additional 3% surcharge. However, you can claim a full refund if you sell your previous main residence within 3 years of buying the new one. The refund must be claimed within 12 months of the sale. This is a valuable lifeline for chain movers who face temporary dual ownership.
## Corporate Buyers - 15% Rate
Companies and non-natural persons (trusts, partnerships) purchasing residential property worth over £500,000 pay a flat 15% SDLT rate, regardless of bands. This was introduced to deter bulk residential property investment by corporate vehicles. Individual directors buying personally are not subject to this - it applies to the corporate entity as purchaser.
## How to Reduce Your Stamp Duty Bill Legally
1. Multiple Dwellings Relief (MDR): When purchasing two or more dwellings in a single transaction (e.g., a property with a self-contained annexe), you can elect for MDR - calculating SDLT as the average price per dwelling, with a minimum effective rate of 1%. MDR was significantly restricted in June 2024 - seek specialist advice.
2. Mixed-Use Property: Properties with both residential and commercial elements (e.g., a flat above a shop, a house with planning consent for commercial use) qualify for non-residential SDLT rates: 0% up to £150,000, 2% on £150k-£250k, 5% above £250k. Significantly cheaper than residential rates for higher-value properties.
3. First-Time Buyer Schemes: Shared ownership schemes have their own SDLT rules - you can elect to pay SDLT only on the purchased share (market value method) or the full value (staircasing approach). The market value method usually results in lower initial SDLT.
4. Negotiating Purchase Price: On a property priced just above an SDLT threshold, negotiating even £1 below can save thousands. At £925,000 the rate jumps from 5% to 10% - buying at £924,999 saves approximately £4,000 versus £925,000.
## Scotland - Land and Buildings Transaction Tax (LBTT)
Scotland replaced SDLT with LBTT in 2015. Rates as of 2026:
| Band | Rate |
|------|------|
| Up to £145,000 | 0% |
| £145,001 - £250,000 | 2% |
| £250,001 - £325,000 | 5% |
| £325,001 - £750,000 | 10% |
| Above £750,000 | 12% |
First-time buyer relief: 0% on first £175,000. Additional dwelling supplement: 6% surcharge.
## When is SDLT Due?
SDLT is due 14 days from the effective date of the transaction (usually completion). Your solicitor handles the SDLT return and payment via HMRC's online portal. Failure to pay on time results in: £100 penalty for first 3 months late, then £200, then interest and further penalties based on the amount unpaid.
Pre-completion, your solicitor will request cleared funds for SDLT alongside the purchase price balance, ensuring same-day payment at completion.
