It had been expected that Mr Sunak was going to announce his second Budget as Chancellor in the autumn, but this was put aside due to the COVID-19 pandemic.
During his speech in the House of Commons on 17th December, Mr Sunak also announced that the Coronavirus Job Retention Scheme (also known as the furlough scheme), which subsidises the wages of employees whose workplace operations are affected by COVID-19, will be extended from March to April 2021.
The Budget will come at a challenging time for the UK economy as it faces the fallout from the COVID-19 pandemic.
Official forecasts have predicted the biggest economic decline in 300 years, with the UK's national income expected to shrink by 11.3% in 2020 and not return to pre-crisis levels until the end of 2022.
Government borrowing is also expected to rise to its highest level outside of wartime, according to the Office for Budget Responsibility.
Mr Sunak said earlier in the year that, although the high levels of borrowing were justified to deal with the virus, “the situation is clearly unsustainable over the medium term”.
However, the Institute for Fiscal Studies said that tax rises of more than £40 billion a year are “all but inevitable” to halt debt from reaching unmanageable levels.
