Chancellor Jeremy Hunt will deliver the 2024 spring Budget on 6 March, the Treasury has said.
It will include the government’s tax and spending plans as well as new growth and borrowing forecasts.
It could be the last chance for the government to announce significant changes to tax policy before the general election.
Reports suggest there may be further tax cuts as the Conservatives try to close a major deficit in the polls.
The chancellor used his last big fiscal speech, the Autumn Statement, to extend tax breaks for business and cut National Insurance.
Ministers have hinted that the next Budget could include bold pledges on housing and taxes, as Prime Minister Rishi Sunak struggles to narrow the gap with Labour ahead of a general election widely expected to be held next year.
Housing Secretary Michael Gove suggested to the Times newspaper that policies to cut costs for first-time buyers could be brought forward.
These could include support to reduce the size of deposits, or a relaunch of the Help to Buy Scheme.
Meanwhile, the Telegraph reported that the prime minister was considering a handful of major tax cuts as he comes under pressure from Tory MPs.
While the move would benefit the wealthy, and few people actually pay it, it is likely to create a clear dividing line with Labour.
The government has not commented on the reports.
The next general election must be held before the end of January 2025 but it is up to Mr Sunak to choose when to call it.
The Office for Budget Responsibility has been formally commissioned to publish economic forecasts on 6 March.
