Understanding the UK Autumn Budget 2025: What Small and Medium Businesses Need to Know

Chancellor Rachel Reeves delivered the 2025 Autumn Budget today, outlining a package aimed at restoring fiscal stability at a time of weak productivity and sustained high borrowing costs.

Below is a practical breakdown of the provisions most likely to affect SMBs, Limited Company Contractors and sole traders, along with considerations for planning ahead.

Tax Changes

Dividend & Savings Income

From April 2026, dividend tax rates will rise by 2 percentage points, reaching 10.75% for basic-rate taxpayers and 35.75% for higher-rate taxpayers. Savings income taxes will increase from April 2027, with rates set at 22% (basic), 42% (higher), and 47% (additional).

Action: Review planned dividend distributions and assess whether salary adjustments or pension contributions may offer more efficient outcomes.

Property Income

A parallel 2 percentage points increase applies to property income tax from April 2027, with rates set at 22% (basic), 42% (higher), and 47% (additional).

Action: Businesses that hold rental property, such as hospitality or franchise operators, may need to reassess property strategies, especially with commercial valuations already under strain.

National Insurance on Pension Contributions

From April 2029, employer pension contributions over £2,000 per employee will be subject to 15% National Insurance, while employees will pay 8% (or 2% on earnings above £50,270).

Action: Evaluate current pension schemes to quantify future costs and consider revising benefit structures.

Frozen Income Tax Thresholds

The government will freeze personal income tax thresholds through 2030–31, a move that the OBR estimates will generate significant revenue as it gradually pushes more taxpayers into higher rate bands.

Action: Make full use of allowable expenses and tax-planning opportunities early in the tax year.

Customs Duties on Parcels

Duties will apply to parcels of any value from April 2026 to address undercutting by online retailers.

Corporate Tax Unchanged

Corporate tax remains largely unchanged providing some welcome stability, though ongoing scrutiny over remuneration and benefits is expected.

Cost Relief

National Living Wage

The new National Living Wage will rise 4.1% to £12.71 an hour from April 2026. While this increases payroll costs, it may help strengthen retention and morale in high-turnover sectors such as retail and care.

Action: Review employee rates prior to April 2026.

Electric Vehicle Mileage Charge

A 3p-per-mile levy for EVs will be introduced from April 2028, generating an estimated annual cost of around £255 per vehicle.

Action: Factor in this charge when assessing the financial case for electrifying fleets.

Energy Support

The Budget includes measures to shift some energy policy costs off household bills and into public spending, a step the Treasury says will reduce bills modestly. Independent analysis and industry bodies have set out possible savings and option. The government expects to absorb 75% of Renewables Obligation costs until 2029. This is expected to reduce average domestic energy bills by £76 per year and provide associated relief for commercial users.

Action: Revisit energy supply contracts to ensure savings are reflected in pricing.

Fuel Duty Freeze

Fuel duty remains at 52.95p per litre until at least September 2026. For logistics dependent businesses, this offers short-term stability. Planned increases from 2027, indexed to inflation, reinforce the case for fuel-efficient or hybrid fleets.

Other Reforms and Announcements

  • ISA Allowance Changes: Cash ISA contributions for under-65s capped at £12,000 annually, with the remaining £8,000 of the £20,000 total allowance reserved for investments.
  • Regional Powers: English mayors will gain authority to impose taxes on overnight hotel and holiday let stays.
  • Broader Economic Initiatives: Trade deals with the US, India, and EU; planning reforms; visa system overhaul; and nuclear power deregulation to facilitate investment.
  • The OBR forecast: UK GDP growth of 1.5% in 2025, with inflation returning to 2% by 2027.

Summary of Major Revenue-Raising Measures and projected yields for 2029-30:

  • Freeze personal tax and employer NI thresholds (from 2028–29): £8.0bn
  • Tax on salary-sacrificed pension contributions: £4.7bn
  • 2-point increase in dividend, property & savings income taxes: £2.1bn
  • Reduced writing-down allowance for corporation tax: £1.5bn
  • EV mileage charge (from 2028): £1.4bn
  • Gambling taxation reforms: £1.1bn
  • Reduced Capital Gains Tax relief for employee ownership trust disposals: £0.9bn

  • Enhanced tax administration & compliance: £2.3bn
  • Other measures (including Sizewell C levy increase): £4.4bn
