Land Transaction Tax (LTT) Wales calculator

Use our tool to calculate your Land Transaction Tax (LTT) when buying a property in Wales.


Think carefully before securing other debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage.

Land Transaction Tax (LTT) is the Welsh version of stamp duty – a tax paid on property purchases.

It’s a tiered system, which is based on the purchase price of your property. This means you’ll pay a different percentage of tax on different portions of the price.

It’s calculated differently to stamp duty in England, Scotland and Northern Ireland.

The bill will differ depending on:

  • Whether or not you’re a first-time buyer.
  • Whether the property is your main residence or a second home.

Here’s how Land Transaction Tax (LTT) in Wales is calculated:

  • Portion costing between £0-£180,000: 0%
  • Portion costing between £180,001 and £250,000: 3.5%

How and when do I pay stamp duty?

Your stamp duty bill is due no more than 30 days after you complete the purchase of a property. Your conveyancer will usually send your stamp duty payment to HMRC on your behalf on completion day.

It is sometimes possible to borrow more from your mortgage lender to fund your stamp duty bill. However, this should be avoided as it means you’ll be paying interest on it for the entirety of your mortgage term.

There is a small list of cases where you’ll be exempt from stamp duty, including with inherited properties, zero-carbon home purchases under £500,000, some Right to Buy transactions and charity purchases. The full list is available on the HMRC website.
