- First-Time Buyer Stamp Duty CalculatorOur first-time buyer stamp duty calculator saves you from one of the most common budgeting mistakes when buying your first home: not knowing what you actually owe until your solicitor asks for the money. Working out the right figure before you make an offer helps you budget with confidence and avoid nasty surprises at completion. In England and Northern Ireland, first-time buyer SDLT relief can wipe out your entire stamp duty bill on properties up to £300,000 - and gives partial relief up to £500,000. This calculator covers the 2026/27 rules for England, Scotland, and Wales so you get the right figure for wherever your property sits.
- LBTT Calculator (Scotland)Use this LBTT calculator to work out the Land and Buildings Transaction Tax due on a Scottish property purchase, including first-time buyer relief and the Additional Dwelling Supplement. LBTT is the tax that replaced Stamp Duty in Scotland, and it applies whenever you buy a home or land above the relevant threshold. Enter your purchase price to see an instant estimate of what you may owe, so you can budget accurately and avoid surprises before you complete.
- LTT Calculator (Wales)Our LTT calculator helps you work out the Land Transaction Tax (LTT) due on a property purchase in Wales, including the higher rates for additional properties. LTT is the Welsh equivalent of Stamp Duty Land Tax and applies whenever you buy a home or land over the relevant threshold. Enter your purchase price to see an instant estimate, whether you are a first-time buyer, moving home, or investing in a second property or buy-to-let.

- Second Home Stamp Duty CalculatorBuying a second home, investment property, or buy-to-let? You'll pay an additional property surcharge on top of the standard stamp duty rates. Our second home stamp duty calculator shows exactly how much you owe across England, Scotland, Wales and Northern Ireland for the 2026/27 tax year. The surcharge adds a flat 5% (or 8% in Scotland) to your bill the moment you own more than one residential property - here's how it works, when it applies, and whether you can avoid it.
- Section 24 Landlord Tax CalculatorThis Section 24 calculator shows how the mortgage-interest restriction changes the tax on your rental income, so you can see your real buy-to-let tax bill rather than guessing. Since the rules fully bit in 2020/21, you can no longer deduct mortgage interest from your rental profit. Instead you get a flat 20% tax credit on finance costs, which hits higher and additional-rate landlords hardest. Enter your rent, mortgage interest and other costs above to estimate the damage for the 2026/27 tax year, then read on for the formula and worked examples.
- Stamp Duty CalculatorThis stamp duty calculator shows what you'll pay in property tax when you buy a home in the 2026/27 tax year, whether that's Stamp Duty Land Tax (SDLT) in England and Northern Ireland, Land and Buildings Transaction Tax (LBTT) in Scotland, or Land Transaction Tax (LTT) in Wales. Enter the purchase price, pick the nation, and flag whether you're a first-time buyer or buying an additional property. Buying a home is stressful enough without a surprise tax bill at completion, so it helps to know the figure before you offer.
- Buy-to-Let Profit CalculatorThis buy-to-let profit calculator shows what you actually keep after costs and tax - including the Section 24 rules that stop individual landlords deducting mortgage interest, and corporation tax if you hold the property in a limited company.
Know the tax before you buy or let
Buying, selling and renting out property all carry their own tax rules, and the bills can be substantial. Our property tax calculators make the numbers clear so there are no surprises at completion or at the end of the tax year.
Buyers should start with the Stamp Duty Calculator, which works out Stamp Duty Land Tax across every band. If you are stepping onto the ladder for the first time, the First-Time Buyer Stamp Duty Calculator applies the relief automatically, while the Second Home Stamp Duty Calculator adds the additional-property surcharge.
For landlords and investors
If you let property, the Rental Income Tax Calculator estimates the tax due on your profits after allowable expenses. The Section 24 Landlord Tax Calculator shows how the restriction on mortgage interest relief affects higher-rate landlords — one of the most misunderstood changes in recent property taxation.
Each tool is updated for the current UK tax year and the latest stamp duty thresholds. Use them together to model the full cost of a purchase and the ongoing tax on rental income, so you can judge a deal on its real after-tax return rather than the headline yield.
