The stamp duty holiday has a tapered extension until the end of September 2021.
Prior to the holiday, stamp duty was payable on any property over £125,000, or for first-time buyers, on properties over £300,000.
Under the current holiday, the threshold has been raised to £500,000 until the end of June 2021 and from then till the end of September 2021 the nil threshold will be reduced to £250,000 before reverting back to the usual £125,000 threshold on 1st October 2021.
As an example, purchasing a property at £400,000 would save you £10,000 if you complete before the end of June 2021, and £2500 if you complete before October 2021.
