Halifax has estimated that an extra four in 10 first-time buyers have been exempt from paying stamp duty as a result of the government raising the starting threshold from £125,000 to £250,000 over the past two years.
The bank says the temporary increase in the threshold has meant that 95% of first-time buyers over the period have not had to pay stamp duty.
An estimated 150,000 first-time buyers have benefitted from the increase in the threshold over the past two years with approximately 380,000 first-time buyers paying no stamp duty.
Returning the starting threshold to £125,000 will result in nearly 45% of first-time buyers paying stamp duty. Halifax said.
The South East and Greater London have benefitted most from the change with around seven in 10 first-time buyers having to pay no stamp duty directly due to the raising of the threshold from £125,000 to £250,000.
The North and Northern Ireland have benefitted the least with only one in six first-time buyers exempt from the tax as a result of the increase.
Only 4% of first-time buyers in Greater London will be exempt from stamp duty when the starting threshold returns to £125,000. Four in five first-time buyers in the South East will pay the tax.
The proportions of first-time buyers paying stamp duty will be much lower in other parts of the country with less than one in five paying the tax in the North and Northern Ireland.
