Notes & assumptions
Assumptions: Residential SDLT rules for England & Northern Ireland. First-time buyer relief applied only when price <= £625,000 (0% up to £425,000; 5% on portion between £425,001–£625,000). Standard bands used if not eligible: 0% to £250,000; 5% £250,001–£925,000; 10% £925,001–£1,500,000; 12% above £1,500,000. Additional property surcharge = 3% of the purchase price; Non-UK resident surcharge = 2% of the purchase price. This tool gives an estimate only — confirm with HMRC and a tax adviser.

Worked examples
Example 1 — First-time buyer, £300,000 purchase
A first-time buyer purchasing a main residence for £300,000.
Interpretation
First-time buyer relief applies: SDLT = £0 (purchase price is under the £425,000 threshold).
Example 2 — Standard buyer, £350,000 purchase
A standard (not first-time) purchaser buying a single main residence for £350,000.
Interpretation
Standard bands apply: 0% on first £250,000 and 5% on £100,000 = £5,000 SDLT total.
Example 3 — Buy-to-let purchaser, £400,000 purchase (additional property surcharge)
Purchaser is buying an additional property (not replacing a main residence).
Interpretation
Standard SDLT on £400,000 = 0% on £250,000 + 5% on £150,000 = £7,500; additional property surcharge = 3% × £400,000 = £12,000. Total estimated SDLT = £19,500.
Frequently asked questions
Does this calculator cover Scotland and Wales?
No. Scotland uses LBTT (Land and Buildings Transaction Tax) and Wales uses LTT (Land Transaction Tax). Use the relevant national tax authority calculators for those jurisdictions.
When does the non-UK resident surcharge apply?
A non-UK resident purchaser surcharge (additional percentage on the purchase price) can apply depending on residency status. Rules and effective dates can change — confirm your status with HMRC guidance or an adviser.
Is this a substitute for professional tax advice?
No. This tool provides estimates only. For a definitive calculation, contact HMRC or a qualified tax advisor.
