The Job Retention scheme is due to end in April 2021 as it stands.
But with growing speculation the current UK lockdown will still be in place long into the spring, there have been calls for this, too, to be extended.
The Times reports Mr Sunak is expected to extended the scheme on March 3, but this has not been confirmed by the Government as yet.
The Stamp Duty holiday is due to end on March 31, and some experts have called for the six-month break to be extended.
The holiday has helped fuel a surge in the housing market, with many buyers and sellers racing to complete their purchases before the scheme expires.
It is thought the end of the scheme could see house prices plummet, but as yet there is no suggestion from the Treasury about whether the scheme could be extended.
However, there’s also speculation Stamp Duty could be scrapped altogether – along with Council Tax – and replaced with a Property Tax.
