Acquiring a residential property in England or Northern Ireland requires understanding the Stamp Duty Land Tax (SDLT). This tax is an immediate additional expense over and above the deposit, and other property purchase-related costs such as the estate agent’s, solicitor’s and surveyor’s fees. For a housing market already grappling with affordability issues, amidst high property prices and high interest rates, understanding SDLT, including calculations, reliefs and timelines, should assist with financial preparedness.
SDLT, commonly referred to as “stamp duty”, is a tax applied to property purchases in England and Northern Ireland above certain purchase price thresholds. It is payable by the property buyer within 14 days of the property being legally transferred into the buyer’s ownership. SDLT is a tiered tax, with higher purchase prices attracting progressively higher rates. The equivalent tax in Scotland is the Land and Buildings Transaction Tax (LBTT) and in Wales it is the Land Transaction Tax (LTT). LBTT and LTT have different thresholds and rates from SDLT.
SDLT Payment and Administration
Though paid by the property buyer, SDLT liabilities are usually handled by the buyer’s solicitor, who files the required returns to HM Revenue & Customs (HMRC). As the assessed SDLT amount requires full payment within 14 days after ownership legally changes hands and the keys are handed over by the seller to the buyer, advance financial planning for payment of this tax is advisable.
SDLT Thresholds and Rates1
If, after buying the property, it is the only residential property the buyer will own, the following SDLT rates apply:
Table 1
Property purchase price
SDLT rate
Up to £250,000
Zero
The next £675,000 (the portion from £250,001 to £925,000)
5%
The next £575,000 (the portion from £925,001 to £1.5 million)
10%
The remaining amount (the portion above £1.5 million)
12%
For example, if the property purchase price is £625,000, Stamp Duty Land Tax is calculated as £250,000 x 0% (i.e. £0) plus £375,000 x 5% (i.e. £18,750) = £18,750.
Relief for First-Time Buyers
If the buyer of the property is a first-time buyer, the following rates apply, provided that the purchase price of the first home does not exceed £625,000:

Property purchase price
SDLT rate
Up to £425,000
Zero
The next £200,000 (the portion from £425,001 to £625,000)
5%
If the property purchase price exceeds £625,000, the standard rates set out in Table 1 above apply.
Additional SDLT on Second Homes and BTL
On the other hand, purchasing a second home or a buy-to-let (BTL) rental investment property incurs an additional 3% SDLT surcharge on standard residential rates:
Table 3
Property purchase price
SDLT rate
Up to £250,000
3%
The next £675,000 (the portion from £250,001 to £925,000)
8%
The next £575,000 (the portion from £925,001 to £1.5 million)
13%
The remaining amount (the portion above £1.5 million)
15%
For example, if the property purchase price is £625,000, Stamp Duty Land Tax is calculated as £250,000 x 3% (i.e. £7,500) plus £375,000 x 8% (i.e. £30,000) = £37,500.
Additional SDLT paid by Non-UK Residents
Non-UK residents pay a further surcharge of 2% over and above the 3% surcharge paid on second homes and BTL properties:
Table 4
Property purchase price
SDLT rate
Up to £250,000
5%
The next £675,000 (the portion from £250,001 to £925,000)
10%
The next £575,000 (the portion from £925,001 to £1.5 million)
15%
The remaining amount (the portion above £1.5 million)
17%
For example, if the property purchase price is £625,000, SDLT is calculated as £250,000 x 5% (i.e. £12,500) plus £375,000 x 8% (i.e. £37,500) = £50,000.
Impact of Higher Mortgage Rates on Managing SDLT
While broader shifts in mortgage interest rates do not directly trigger SDLT changes, they do impact overall affordability for buyers. Given that house prices are already stretching budgets, especially for first-timers, high SDLT payments at completion add a further financial burden. This affordability squeeze is even more pronounced in expensive city centres.
So, in times when monthly mortgage payments are rising, gathering together a large sum for upfront SDLT payment which becomes due within 14 days after completion risks delaying the transaction if funds are tied up elsewhere. Careful financial planning for all immediate upfront purchase costs, including deposits, SDLT, legal fees, estate agent fees and surveyor fees, ensures preparedness.
Future Changes in Rates2
Stamp duty rates are subject to change, based on government policy.
Before 23 September 2022, the Stamp Duty Land Tax (SDLT) rates were structured as follows: 0% up to £125,000, 2% from £125,001 to £250,000, 5% from £250,001 to £925,000, 10% from £925,001 to £1,500,000, and 12% for amounts above £1,500,000.
However, following the mini-budget announced on 23 September 2022, several adjustments were made to SDLT rates. The nil-rate band was increased from £125,000 to £250,000. As a result, SDLT rates were adjusted to 0% up to £250,000, 5% from £250,001 to £925,000, 10% from £925,001 to £1,500,000 and 12% for amounts above £1,500,000.
Additionally, the threshold for first-time buyers was also changed. Previously, first-time buyers started paying SDLT from £300,000 onwards, but this was increased to £425,000. Moreover, the maximum value of a property on which first-time buyers can claim relief was increased from £500,000 to £625,000.
The current rates that came into force on 23 September 2022 and these are scheduled to last until 31 March 2025.
Thereafter, from 1 April 2025 onwards, SDLT is scheduled to revert to the higher older rates as described above.
To conclude, as an inevitable accompaniment to the dream of UK home ownership, understanding SDLT obligations should help plan for the road ahead with more confidence.
