Common questions
When is the next UK Budget?
The Chancellor normally delivers one major fiscal event each autumn, with a smaller Spring Statement providing an economic update and occasional tax changes. Dates are confirmed by HM Treasury a few weeks in advance. We update these guides on the day of each event with the measures that affect accountants, businesses and individuals.
What is the difference between the Budget and the Spring Statement?
The Budget is the main annual fiscal event, where the Chancellor sets out tax and spending decisions for the year ahead. The Spring Statement is a lighter update responding to the Office for Budget Responsibility forecast. In practice the Spring Statement can still contain significant tax announcements, so both are worth reading.
When do Budget tax changes take effect?
It varies by measure. Income tax and National Insurance changes usually start at the beginning of the tax year on 6 April. Corporation tax changes often align with the financial year from 1 April. Some measures, particularly duty rates and anti-avoidance rules, take effect immediately or from midnight on Budget day. Each of our explainers states the commencement date for the measures it covers.
