UK Budget 2026/27: What Changed for Your Taxes and Finances

The UK's 2026/27 tax year began on 6 April 2026, shaped by the Autumn Budget delivered by then-Chancellor Rachel Reeves on 26 November 2025. Since then, UK politics has shifted meaningfully — including a change of Prime Minister — but the tax rules set in that Budget remain the foundation for your 2026/27 finances. Here's what actually changed, and what's coming next.

The Headline: A £26 Billion Tax Increase

The November 2025 Budget raised taxes by roughly £26 billion, continuing a trend of significant fiscal tightening. Despite the scale of this figure, the Budget itself was described by analysts as a "steady-as-she-goes" package rather than a structural overhaul — meaning most of the impact comes from extending existing freezes and adjusting specific measures, rather than dramatic headline rate changes.

Key Changes Now in Effect (2026/27 Tax Year)

• Personal tax threshold freeze extended — the freeze on income tax thresholds (Personal Allowance, basic and higher rate bands) has been extended from April 2028 all the way to April 2031. Combined with wage growth, this continues to pull more people into higher tax brackets over time — a phenomenon known as "fiscal drag."
• Dividend tax increases — dividend tax rates rose in April 2026 for income held outside ISA allowances, affecting anyone with investment income beyond their tax-free wrapper.
• National Insurance changes on pension salary sacrifice — changes to how salary sacrifice arrangements for pensions are treated under National Insurance took effect, affecting take-home pay calculations for employees using this common tax-efficient pension contribution method.
• VAT and business rates — the headline VAT rate remains at 20%, with reduced (5%) and zero rates unchanged for essential goods; business rates saw new lower multipliers introduced for eligible properties in England.
• Fuel duty — the temporary 5p cut and rate freeze were extended to September 2026, with a planned staged reversal beginning after that point.

Changes Coming Later in 2026 and 2027

Several of the Budget's more significant measures don't take effect immediately:

• Quarterly tax reporting for sole traders and landlords earning more than £50,000 begins in the 2026–2027 tax year, though the government has confirmed no late-submission penalties will apply during this first transitional year — the new penalty regime starts from 6 April 2027.
• Inheritance tax on private pensions — a change first announced in autumn 2024 — takes effect from April 2027.
• A "mansion tax" on higher-value properties is set to launch in April 2028.
• ISA cash allowance changes and further salary sacrifice pension limits are scheduled for 2027–2029.

The overall UK "tax take" — income tax, National Insurance, VAT, and corporation tax combined — is projected to rise from 34.5% of GDP in 2024/25 to 38.5% by 2030/31, which would mark a post-1945 high.

A Notable Political Development: New Prime Minister

As of 20 July 2026, Andy Burnham formally took up the role of UK Prime Minister, appointing a new Chancellor and Treasury ministers. One of his first announced moves was a pledge to remove VAT from domestic electricity bills from 1 October 2026, expected to save households roughly £45 a year. This change in leadership adds genuine uncertainty to the timing and content of the next Autumn Budget, expected sometime between late October and late November 2026.

What This Means If You're an Immigrant or Newcomer to the UK

• Threshold freezes affect everyone equally, including new arrivals — as your salary grows, expect a larger share to fall into higher tax bands than in previous years, even without a change in your circumstances.
• If you're self-employed or a landlord earning over £50,000, prepare for quarterly reporting requirements beginning this tax year, even though penalties are deferred until April 2027.
• New UK residents benefiting from the Foreign Income and Gains (FIG) regime should note that this framework remains separate from the general Budget measures above, but is worth reviewing alongside your overall tax position if you're newly arrived.
• Watch for the Autumn Budget 2026, likely in October or November, which — under the new government — could bring further changes given the change in political leadership.

Application Checklist

• Review your income against the frozen tax thresholds to anticipate any bracket changes for 2026/27.
• If self-employed or a landlord earning over £50,000, prepare for quarterly reporting starting this tax year.
• Check whether the pension salary sacrifice National Insurance changes affect your take-home pay calculations.
• Factor dividend tax increases into any investment income held outside an ISA.
• Monitor announcements from the new government ahead of the Autumn Budget 2026.
• Speak with a UK accountant if you're newly arrived and unsure how these changes interact with your specific residency status.
