The government exempted the majority of home buyers in England and Northern Ireland from paying stamp duty tax in July
Chancellor Rishi Sunak announced the cut last month, stating: "Right now, there is no stamp duty on transactions below £125,000.
"Today, I am increasing the threshold to £500,000. This will be a temporary cut running until March 31 2021 - and, as is always the case, these changes to stamp duty will take effect immediately.
"The average stamp duty bill will fall by £4,500. And nearly nine out of 10 people buying a main home this year, will pay no stamp duty at all."
The measure is a temporary one and has been billed a “stamp duty holiday”.
When will the new measures come into force?
Mr Sunak said that the measure would be in place until March 31, 2021.
