Which tax applies to your purchase?
Where the property sits decides it, not where you live. Buy in England and you pay Stamp Duty Land Tax to HM Revenue and Customs under the Finance Act 2003. Buy in Wales and you pay Land Transaction Tax to the Welsh Revenue Authority, which replaced the English tax for Welsh property from 1 April 2018. Both work in bands, but the thresholds and rates differ. Wales gives first time buyers no relief at all and sets a higher starting threshold for everyone instead, and Wales allows thirty days to file and pay where England allows fourteen, under sections 44 and 57 of the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017 and section 76 of the Finance Act 2003, checked 20 September 2026. A buyer who assumes the English rules apply in Cardiff gets the wrong answer.
Scotland charges Land and Buildings Transaction Tax, which this calculator does not cover. We act in England and Wales only.
Why is the tax charged in bands?
Since 2014 the tax has worked like income tax: each slice of the price carries its own rate. A home a single pound over a threshold does not pay the higher rate on the whole price, only on that pound. That is why the band table matters more than the headline rate.
Government sets the bands and rates and changes them at Budgets. This page shows the date the rates came into force and the date we last checked them against the published source. Every band below was checked against the HMRC and Welsh Revenue Authority pages on 20 September 2026 and none had moved.
What counts as the price for land tax?
Everything given for the property, which the law calls the chargeable consideration. For most buyers that is simply the price. It also includes any mortgage debt you take over and the value of any work or services you do for the seller, which is why a transfer of equity with no cash changing hands can still carry tax.
Fixtures, meaning things attached to the property such as a fitted kitchen, are part of the land and taxed with it. Removable contents, curtains, freestanding appliances, furniture, can be paid for separately and left out, but only at an honest value. An inflated contents figure that drags the price under a threshold is a well-known trigger for an HMRC or WRA enquiry.
Two or more deals between the same buyer and seller, or people connected to them, as part of one arrangement are linked transactions. The tax is then worked out on the combined price. A house and a paddock bought from the same seller a month apart can be linked transactions, and they do not have to complete on the same day for that to happen. What the combined figure does is set the rate. The tax worked out at that rate is then shared between the deals in proportion to what each one cost, so you do not put the combined price on a single return (section 55(1C) of the Finance Act 2003, and section 28 of the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017, checked 20 September 2026). Watch the second purchase: where it is the later deal that first takes the pair over a threshold, a further return can be due on the earlier one as well, counted from the later completion. A transaction in Wales is never linked to one in England, because each tax only reaches land in its own country.
What counts as a first time buyer?
For the English relief, every buyer named on the transfer must never have owned a home anywhere in the world, and must intend to live in the property as their only or main residence. Inheriting a share of a property counts as owning it. If one of two buyers has owned before, both lose the relief. The conditions are in Schedule 6ZA to the Finance Act 2003, checked 20 September 2026.
A price ceiling caps the relief. Above it you get no relief at all, not a tapered one, so a home just over the line pays the full standard rates.
When do the higher rates for additional properties apply?
When you still own another dwelling once completion day has passed, and the home you are buying does not replace your main residence. That catches buy to let, holiday homes, and a new home bought before the old one has sold. In the last case the extra tax can be reclaimed if the old home sells within the allowed period, by a claim you or your conveyancer make to HMRC or the WRA; nothing is repaid automatically. In England the old home has to sell within three years beginning with the day after you completed the new purchase, and the claim runs to its own twelve month deadline; Wales runs to a different one. Schedule 4ZA paragraphs 3 and 8 to the Finance Act 2003 and Schedule 5 paragraphs 8 and 23 to the Welsh Act, checked 20 September 2026. Choose the additional property option in the calculator above to see the higher rates.
Companies buying residential property pay the higher rates every time, and above 500,000 pounds a flat rate of 17 per cent can apply instead, under Schedule 4A paragraphs 1(2) and 3(1)(a) to the Finance Act 2003, read on legislation.gov.uk on 20 September 2026. Reliefs exist for a genuine property rental or development business and have to be claimed.
What if the property is mixed use or more than one dwelling?
A single purchase that includes both residential and non-residential land, a shop with a flat above, a house with farmland, is charged at the non-residential rates, and the additional property surcharge does not apply, under section 55(1B) of the Finance Act 2003 with the definition of residential property in section 116, checked 20 September 2026. There is no size limit and no reasonable enjoyment test in the Act, so whether attached land is garden or grounds is fought case by case. HMRC challenges claims where the non-residential element is token, and the facts need to be genuine.
Several dwellings bought together follow their own rules. Multiple dwellings relief was abolished in England for transactions with an effective date on or after 1 June 2024, by section 7 of the Finance (No. 2) Act 2024, checked 20 September 2026. The test is the effective date and not completion loosely described, and the relief survives where the contract was entered into and substantially performed before that date, or entered into on or before 6 March 2024 and not varied since. A purchase of six or more dwellings at once is still treated as not residential property under section 116(7) of the Finance Act 2003, which the abolition did not touch. Wales still has its own relief under Schedule 13 to the Welsh Act, but the minimum tax where it is claimed rose from 1 to 3 per cent of the price attributable to the dwellings for effective dates from 13 February 2026, under W.S.I. 2026/40 (checked on legislation.gov.uk 26 September 2026), with the same kind of protection for contracts already exchanged and substantially performed. This calculator does not handle any of these cases.
Who pays the tax and when?
The buyer. Your conveyancer files the return and pays the tax from the completion funds, which is why it appears on your completion statement and must sit in the account before the day. In England the return and the tax fall due within fourteen days of completion; Wales allows thirty. A return is usually needed even where no tax is due, because the duty to notify starts at 40,000 pounds of chargeable consideration and both nil rate bands sit well above that: 125,000 pounds for residential property in England and 225,000 pounds in Wales. Below 40,000 pounds there is no return to file and no penalty to incur. Where the transaction is notifiable, the certificate HMRC or the Welsh Revenue Authority issues in response to the return is what HM Land Registry needs for most applications before it will register you. Where it is not notifiable there is no certificate and none is required, and what goes in with the application instead is an explanation of why (sections 77A and 79 of the Finance Act 2003, sections 46 and 65 of the Welsh Act, and HM Land Registry Practice Guide 1, checked 20 September 2026). Late filing carries a penalty even where you owe nothing.
The return is yours. Your conveyancer prepares it, but you sign the declaration, so read the questions about other property and first home status before it goes. When we act for you, we calculate the figure on the facts of your file, not on this page, and confirm it to you in writing before exchange.
