Stamp Duty 2026: Changes & History | UK

Updated: 20 May 2026

Introduction to Stamp Duty

Stamp Duty, also known as Stamp Duty Land Tax (SDLT), is a tax levied on the purchase of property in the United Kingdom. The tax is typically paid by the buyer and is calculated based on the purchase price of the property. The stamp duty threshold, which is the minimum amount at which the tax is payable, has undergone several changes over the years.

Historical Context of Stamp Duty Threshold

The stamp duty threshold has been adjusted numerous times to reflect changes in the property market and the economy. In the past, the threshold was as low as £60,000, but it has been increased to £125,000 for residential properties and £150,000 for non-residential properties in the tax year 2026. This increase in the threshold has resulted in a significant reduction in the amount of SDLT payable for many buyers.

Changes to Stamp Duty Land Tax (SDLT) Rates

The rates of SDLT have also changed over the years. In the tax year 2026, the rates are as follows:

Impact of Stamp Duty Threshold on First-Time Buyers

The increase in the stamp duty threshold has had a significant impact on first-time buyers. In the tax year 2026, first-time buyers are exempt from paying SDLT on the first £300,000 of the purchase price, provided the property is worth no more than £500,000. This exemption has made it easier for first-time buyers to get onto the property ladder, as they do not have to pay SDLT on the majority of the purchase price.

Additional Charges for Second Homes and Buy-to-Let Properties

Buyers of second homes and buy-to-let properties are subject to an additional 3% charge on top of the standard SDLT rates. This charge applies to all properties, regardless of their value, and is intended to help control the demand for housing and reduce the burden on first-time buyers.

Future Expectations for Stamp Duty Threshold

The future of the stamp duty threshold is uncertain, as it is subject to change based on government policy and economic conditions. However, it is likely that the threshold will continue to be adjusted to reflect changes in the property market and the economy. In the tax year 2026, the UK government has announced plans to review the SDLT system and consider making further changes to the threshold and rates.

Potential Reforms to SDLT

There have been several proposals for reforming the SDLT system, including introducing a more progressive tax system and increasing the stamp duty threshold for certain types of properties. Some experts have suggested that the government could introduce a tiered system, with higher rates for more expensive properties and lower rates for lower-priced properties. However, any changes to the SDLT system would require careful consideration of the potential impact on the property market and the economy.

Conclusion

The stamp duty threshold has undergone significant changes over the years, with the most recent increase to £125,000 for residential properties and £150,000 for non-residential properties in the tax year 2026. The impact of these changes on buyers, particularly first-time buyers, has been significant, with many benefiting from the increased threshold and exemptions. As the property market continues to evolve, it is likely that the stamp duty threshold will continue to be adjusted to reflect changes in the economy and government policy.
