When does the Budget come into effect 2025? Will changes be made straightaway - as Rachel Reeves makes announcement today
Chancellor Rachel Reeves will set out her tax and spending plans when she delivers her Budget today.
The chancellor will speak for around an hour. The Leader of the Opposition, Kemi Badenoch, will then offer her response before MPs begin a days-long debate on the proposals.
After this the Office for Budget Responsibility will publish its latest economic and fiscal outlook, plus there will be analysis from economic think tanks like the Institute for Fiscal Studies. Rachel Reeves has just been snapped leaving 11 Downing Street - her official residence - with the traditional red box in hand.
Fresh out of a lengthy cabinet meeting, the chancellor will now make her way to the House of Commons to announce the Budget at 12:30pm.
The Budget’s provisions do not take effect as a single event, it varies to align with the UK's fiscal year (April 6 to April 5) and legal requirements. Adjustments to the likes of duties on alcohol, tobacco, or certain taxes like capital gains can enter force at 6:00 PM on Budget day via the House of Commons' Provisional Collection of Taxes motion, which is typically passed by convention without debate.
Most tax and spending changes are effective from April 6, 2026 (start of the 2026/27 fiscal year), after the Finance Bill receives Royal Assent. This includes income tax, corporation tax, VAT, and national insurance adjustments.
Items like carried interest tax changes, Agricultural Property Relief reforms, and Making Tax Digital for income tax rollout begin April 6, 2026. Welfare reforms including crapping the two-child benefit cap would be a phased rollout starting late 2026, with full effects by 2027/28. Pension and salary sacrifice schemes would be effective from April 2026.
