Property & Tax

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.
