Stamp duties are levied on conveyances and transfers of land and property, and on securities (share and bond) transactions. The term comes from the fact that historically stamps on documents, following their presentation to the Stamp Office, indicated payment. Land and property transactions are now charged Stamp Duty Land Tax (SDLT), whereas electronic transfers in securities are charged Stamp Duty Reserve Tax (SDRT). In 2019/20 stamp duties raised £15.1 billion in total. SDLT accounted for just over three quarters of this total (£11.6 billion); receipts from just residential properties were £8.4 billion.[1]

Historically stamp duty land tax (SDLT) has been charged at a single rate on the whole purchase price of a property, with different rates for different value bands. When the sale price of a property exceeded the threshold for a higher rate of duty, tax would be charged on a ‘slab basis’, at the higher rate on the whole value of the sale rather than the part of the price above the threshold.  The tax has been charged at the same rate of tax irrespective of the number of residential properties owned by the buyer.

Both of these aspects of the tax have been reformed in recent years.

First, in his Autumn Statement in December 2014 the then Chancellor George Osborne announced that in future SDLT would be charged on residential property on a ‘slice basis’: rates would only apply to the part of a property’s selling price that fell within each value band. New rates and thresholds would be introduced, with effect from 4 December 2014, to ensure that in removing these distortions, most buyers would not have to pay more tax. In addition, as Mr Osborne explained, “anyone who has exchanged contracts but not completed by midnight [on December 3] will be able to choose whether to pay under the old system or the new, so no one in the middle of moving house will lose out.”[2] It was estimated that this reform would cost £395m in 2014/15, rising to £760m in 2015/16.[3] To give effect to these changes the Government introduced primary legislation: the Stamp Duty Land Tax Act 2015.[4]

Second, in his Autumn Statement in December 2015 Mr Osborne announced that from 1 April 2016 new higher rates of SDLT would apply on the purchase of additional residential properties, such as second homes and buy-to-let properties. The Government launched a consultation exercise on how the new rates would apply. In the 2016 Budget the Chancellor announced certain modifications to the Government’s original plans, though the main principle underpinning the new duty regime would remain: the higher rates apply on a purchase if, at the end of the day, the buyer ends up with more than one property, but not if the property purchased is to replace one’s main residence, which is being sold.[5] The new higher rates were forecast to raise £675m in 2016/17, rising to £750m in 2017/18.[6]

Mr Osborne also announced that the structure of SDLT on commercial property would be reformed, so that the tax would be charged on a ‘slice basis’, in the same way as residential property. The Chancellor summarised the impact of the new duty regime as follows: “commercial stamp duty will have a zero rate band on purchases up to £150,000, a 2% rate on the next £100,000, and a 5% top rate above £250,000. There will also be a new 2% rate for those high-value leases with a net present value above £5 million … These reforms raise £500 million a year and while 9% will pay more, more than 90% will see their tax bills cut or stay the same.”[7]

Provision to give effect to both of these changes to the tax was included in the Finance Act 2016 (specifically s128 and s127 of the Act).

More recently there have been two further reforms to SDLT: a new relief for first-time buyers, and a temporary SDLT ‘holiday’ introduced as part of the Government’s response to Covid-19.

In the 2017 Autumn Budget the then Chancellor Philip Hammond announced that for first time buyers, the price at which a property became liable for SDLT would be set at £300,000. The relief would come in with immediate effect but would not apply for purchases of properties worth over £500,000. It was estimated that the new relief would cost £125m in 2017/18, rising to £560m in 2018/19.[8] Provision for the new relief was included in the Finance Act 2018 (specifically s41 of the Act).[9] Subsequently in the 2018 Budget Mr Hammond announced that the relief for first-time buyers would be extended to all ​first-time buyers of shared ownership properties valued up to £500,000. Relief would be retrospective to ensure first time buyers who had previously made a purchase would benefit.[10]

The Chancellor Rishi Sunak did not propose any major changes to SDLT in the 2020 Budget, but as part of his Plan for Jobs, presented on 8 July 2020, he announced a temporary increase to the nil rate band (NRB) for residential house sales, from £125,000 to £500,000.[11] The new NRB would apply from 8 July 2020 to 31 March 2021, at an estimated tExchequer cost of £3.2bn.[12] In recent weeks there has been speculation the Government might extend this relief, and in his Budget statement on 3 March the Chancellor announced that the new NRB would be extended to 30 June. In addition a NRB of £250,000 would apply from 1 July to 30 September 2021.[13] It is estimated this additional relief will cost £1.5bn in total.[14] HMRC has published guidance on this extended tax relief.[15]

While this briefing discusses these reforms to the taxation of residential property, a second Commons Library briefing Paper looks at the wider issues of housing need and housing supply.[16]

Guidance on SDLT is collated on This includes an online calculator for those who wish to determine how much duty they are liable to pay, on transactions for both residential and commercial property.

Over this period SDLT has been devolved to both Scotland (from April 2015) and Wales (from April 2018). Both the Scottish and Welsh Governments charge their own replacement taxes: the Land and Buildings Transactions Tax collected by Revenue Scotland; and the Land Transaction Tax collected by the Welsh Revenue Authority. In both cases higher rates of tax are charged where the purchaser already owns a residential property, and in the case of Scotland, tax relief is also provided for first time buyers. Statistics on each of these taxes are published by Revenue Scotland and the Welsh Revenue Authority. In addition the Office for Budget Responsibility publishes statistics on historic receipts and projected revenues from all three of these property transaction taxes. The OBR’s most recent forecast is that in 2021/22 SDLT will raise £11.3 billion, while its Scottish and Welsh equivalents will raise £700m and £300m respectively.[17]
