One tax. Since 2019.
Stamp.Expert does one thing: stamp duty. Stamp first launched for conveyancers in 2019 as Stamp Check. In 2026 we rebuilt it from the ground up, sharpening the questions so the firms that use it can see a complex purchase coming.
A calculator gives one number. Nearly half of purchases need more.
Most stamp duty mistakes don't start with the maths. They start with an answer: a share in a flat abroad that never came up, a home that isn't being sold after all, a separation with no court order. The fee-earner types up what they heard, the calculator does its job, and the file shows a figure with no working behind it.
Stamp starts with the client's own answers, on their own phone, and says plainly when the answer isn't simple.

*Stamp.Expert data for checks completed in 2026, up to November 2026. Non-standard means something in the client's answers makes the stamp duty uncertain. Best and worst cases are the two ends of the range shown to the client; the amount actually due depends on the facts and, for non-standard purchases, on advice from a tax adviser. Stamp.Expert does not give tax advice.
Three things we won't bend on.
The client answers.
The person who knows the facts answers the questions. No translation, no typing up a phone call.
Advice stays independent.
Stamp has no in-house tax advisers. When a case is complex, the client chooses an independent tax firm from an open panel, or their own adviser.
Honest about limits.
Stamp reduces your risk and leaves you a defensible file. It doesn't take away your responsibility, and we won't say it does.
