PROPERTY GUIDE
How much Stamp Duty on a £300,000 house?
Stamp Duty Land Tax depends on the price and the buyer's circumstances. England and Northern Ireland use SDLT; Scotland and Wales have different property taxes.
STANDARD £300,000 EXAMPLE
The SDLT is calculated in bands, not at one rate.
Under the current standard residential bands, the first £125,000 is charged at 0%, the next £125,000 at 2%, and the final £50,000 of a £300,000 purchase at 5%. That produces £5,000 of SDLT under the standard scenario.
£125,001 to £250,000
2% applies to this £125,000 portion.
£250,001 to £300,000
5% applies to the final £50,000 portion.
Calculation: £125,000 × 0% = £0; £125,000 × 2% = £2,500; £50,000 × 5% = £2,500. Standard SDLT therefore totals £5,000 on this simplified £300,000 scenario.

BUYER STATUS CAN CHANGE THE BILL
£300,000 does not produce one SDLT result for everyone.
A qualifying first-time buyer may pay 0% on the first £300,000 under the current relief. An additional-property purchase can attract higher rates, while a non-UK-resident surcharge can also apply in qualifying circumstances.
Important: if you are a first-time buyer, do not simply assume that the standard calculation is your answer. Check whether you qualify for the relief and whether the property price and joint-buyer circumstances meet the conditions.
JURISDICTION
Make sure you are using the right property tax.
Scotland uses Land and Buildings Transaction Tax and Wales uses Land Transaction Tax. This guide is specifically about residential SDLT in England and Northern Ireland.
Specialist transactions such as linked purchases, corporate transactions, multiple dwellings or particular reliefs can require a different analysis.

WHY THE BUYER PROFILE CHANGES THE RESULT
£300,000 is the property price, not the whole tax question.
For residential SDLT in England and Northern Ireland, the rate is applied to slices of the transaction value. Buyer status can then change which rates or reliefs apply. This is why a headline number should always show the scenario behind it.
Standard single-property case
Under the current standard bands, the £300,000 price produces £5,000 of SDLT: £0 on the first £125,000, £2,500 on the next £125,000 and £1,500 on the final £50,000.
Qualifying first-time buyer
Current relief can mean no SDLT on the first £300,000, subject to the published conditions. A purchase above £500,000 does not qualify for the first-time-buyer relief.
Other circumstances
Additional-property and non-UK-resident rules can create higher charges. Transaction structure can also matter, so unusual purchases should not rely on a simplified example.
