If you are planning to buy a property in the UK or Northern Ireland, you may need to pay Stamp Duty Land Tax (SDLT), even as a non-resident. To simplify this process, calculator-online has designed an interactive stamp duty calculator for the UK. It helps you estimate what you might owe to HMRC (Her Majesty's Revenue and Customs). Our tool also supports calculating stamp duty for Australian states including NSW, VIC, QLD, WA, SA, ACT, NT, and TAS.
SDLT, introduced in 2003, is a tax payable on the purchase of land or property in the UK. Any property transaction over £40,000 must be reported to HMRC to obtain a Land Transaction Certificate from the Land Registry. SDLT is generally payable by the buyer within 14 days of completing the purchase.
For buyers who do not already own property in the UK or overseas, SDLT is calculated based on the following thresholds:
Use the SDLT calculator to quickly determine the exact amount payable.
This advanced calculator helps you determine stamp duty for both residential and commercial properties in the UK and Australia. It accounts for factors such as first-time buyers, property type, and the state or territory in Australia.
There are three common ways to pay SDLT:
Sign an agreement on non-judicial stamp paper and submit it to the sub-registrar within 4 months to maintain validity.
Some states allow online payment via government websites. You can download receipts and forms to submit to the registrar.
Payment can also be made using a blank paper submitted to an authorized bank for stamping.
SD is calculated on the property’s purchase price. Stamp duty is a state tax and varies between regions, generally ranging from 3–10%.
SD can also be calculated using the circle rate (minimum value set by local authorities). The higher of the property price or circle rate is used for calculation.

First-time buyers in the UK (as of 22 November 2017) are exempt from SDLT on properties up to £300,000. For properties above this, SDLT is charged at 5% on the portion exceeding £300,000.
Pay within 3 months of settlement. Rates vary depending on purchase price, e.g., $80,001–$300,000: $1,290 + $3.50 per $100 above $80k.
Pay within 30 days of transfer. Example: $440,001–$550k: $18,370 + 6% of value above $440k.
Pay within 30 days of contract. Example: $75k–$540k: $1,050 + $3.50 per $100 above $75k.
Pay within 2 months. Example: $100,001–$250k: $2,090 + $3.80 per $100 above $100k.
Pay on or before settlement. Example: $250k–$300k: $8,955 + $4.75 per $100 above $250k.
Pay at settlement date. Duty varies based on property type and value.
Pay within 60 days of agreement. Use the calculator for current transfer rates.
Example: $200k–$375k: $5,935 + $4 per $100 above $200k.
Some buyers may qualify for concessions depending on state/territory rules.
Removable fixtures (like fridges or carpets) are not included in SDLT, while fixed items (like light switches) are. Adjusting the purchase price with the vendor can reduce SD liability.
All residential property buyers in the UK must pay SDLT, including non-residents. No exemptions or personal allowances apply.
Calculator-online’s SDLT tool helps UK, Northern Ireland, and Australian buyers estimate their stamp duty obligations. After paying SDLT and registering the property, the buyer becomes the official owner of their new home. Always ensure your property is purchased from a reliable builder!
