The chancellor is facing calls to cut taxes and raise public sector pay after the government recorded a surprisingly large £5.4bn surplus last month.
The balance sheet is typically in surplus in January because of tax receipts from self-employed workers, but this year the figure was £5bn higher than predicted by the Office for Budget Responsibility. Public borrowing for the year was also £30bn below the OBR’s November forecast.
Capital gains tax payments hit £13.2bn in January – up 24% from the same month in 2022 – as investors hurried to lock in gains ahead of speculation about tax rate rises last spring.
