Autumn Budget 2025: What to Expect

The Autumn Budget 2025 is shaping up to be one of the most closely watched fiscal events in recent years. With Chancellor Rachel Reeves scheduled to deliver the statement in November, many small business owners are rightly asking, “What could this mean for me?”

With economic uncertainty mounting and a significant fiscal shortfall forecast by the Office for Budget Responsibility, speculation is focusing on potential tax rises, relief cuts and changing business policies.

How important is the Autumn Budget?

This is the UK government’s opportunity to lay out its tax and spending plans for the upcoming financial year. Unlike the Spring Statement, which often includes updates or mid-year adjustments, the Autumn Budget is the major fiscal event.

For small businesses, this is when policy changes are announced that can impact everything from payroll costs and VAT obligations to investment reliefs and grant schemes. Whether you’re a sole trader, a growing SME, or running a limited company, decisions made in November could directly affect your bottom line.

When is the Autumn Budget?

Mark your calendar for 26th November 2025, just after 12.30pm, immediately following Prime Minister’s Questions. The Chancellor’s speech is expected to be broadcast live on major news channels like BBC and Sky News. It can also be streamed online via BBC iPlayer, the BBC News website and Parliament TV. Some sources also indicate that the Sky News YouTube channel may provide live coverage.

Limited room for tax increases?

The government has emphasised its commitment not to raise income tax rates, National Insurance, VAT, or the main rate of Corporation Tax. Together, these account for about 75% of total tax revenue, so where does that leave the Chancellor?

The answer, it seems, is in exploring less obvious routes - adjusting thresholds, tightening reliefs, or introducing sector-specific taxes. While the headlines may say “no tax rises”, the fine print could still mean higher costs for business owners.

One possibility is the government could extend the freeze on income tax thresholds beyond 2028, increasing tax revenue through what’s known as “fiscal drag” - a stealthy way to move earners into higher bands as wages rise.

Changes to Corporation Tax or business tax reliefs?

Corporation Tax is unlikely to increase beyond its current headline rate of 25%, a figure the government has promised to cap throughout this Parliament. However, this doesn’t mean all is quiet on the tax front. In fact, reliefs and allowances are likely to be under the microscope. The Annual Investment Allowance and Research & Development Tax Credits, both vital for business planning and growth, could be revised or restructured.

If your business currently benefits from these incentives, this is a good time to review your future investment plans. DL Accounts, an experienced accountant Cornwall firms rely on, can help assess your opportunities before the Budget hits.

Will the Budget affect payroll, NI or employment costs?

Changes announced in the Autumn Budget 2024 included a rise in employer National Insurance contributions, starting April 2025. That move alone is raising significant revenue from employers, especially impacting small businesses with tight margins.

There could be more to come, as one area being closely watched is salary sacrifice. This tax-efficient arrangement, where employees exchange part of their salary for pension contributions, may face new restrictions. The Treasury could limit exemptions or cap how much can be sacrificed, reducing its attractiveness for both employers and staff.

There are also whispers of changes to Employment Allowance and another potential National Minimum Wage rise in the next tax year. Combined, these would push up employment-related costs even further. For any small business trying to forecast costs or plan recruitment, this is a critical area to watch.

Is VAT in the spotlight?

There’s ongoing speculation that the VAT threshold could be lowered - possibly below its current level of £90,000 in turnover. This would force thousands more small businesses into VAT registration, increasing administrative burdens and possibly reducing competitiveness, especially for micro-businesses or freelancers. Alternatively, the government might opt to raise the threshold, as some industry groups have proposed. Either way, if your business hovers near the VAT line, it’s time to consider your strategy.

The other headline here is the government’s interest in digital reporting and e-invoicing. Following a consultation earlier this year, the Autumn Budget 2025 could include new steps towards modernising tax processes, including possibly mandating e-invoicing for certain sectors. If this is introduced, it could require significant operational adjustments.

Business Rates reform: what we know so far

Another major area where changes are expected is Business Rates. The government has signalled reform could be in the pipeline, especially to remove barriers to investment and support high street recovery. The upcoming Budget may introduce a marginal rate system, enhance Small Business Rates Relief, and provide improvement incentives for property upgrades. If your premises are currently near the edge of the SBRR threshold, even small changes could dramatically affect your costs.

The merger of the Valuation Office Agency with HMRC, due by the end of the current financial year, may also speed up future rate changes, making it even more important to stay on top of these developments.

Wealth and property impacts

Beyond business taxes, the government may look to raise revenue from wealth and property. While Chancellor Reeves has ruled out a full-blown “wealth tax”, there’s still pressure to reform Capital Gains Tax, Inheritance Tax and Stamp Duty Land Tax. Changes being floated include a lifetime cap on tax-free gifts, NI charges on rental income (a potential hit for landlords) and limits to primary residence CGT relief.

If you’re a business owner with significant property and investments, or planning to pass on wealth, these proposals could impact you directly. Early planning with professional tax services Cornwall businesses trust could help provide a lifeline and guide you on the best way forward.

Are there any new grants or support schemes?

There’s cautious optimism that new support measures will be introduced, especially for small and growing businesses. These could come in the form of targeted grants, innovation funds, or additional investment incentives. Labour’s newly formed Budget Board suggests a more “pro-business” tone, but with the fiscal hole looming, the schemes may be limited or highly targeted.

That said, Cornwall-based businesses, especially in retail, hospitality and tourism, may benefit from regional or sector-specific support, so it’s worth keeping an eye on announcements tailored to local areas.

How small business owners can prepare

With so much uncertainty, what can you do right now? Start by reviewing your tax position, reliefs, payroll costs and business rates. If you’re near the VAT threshold, make a plan for what happens if it moves. If you benefit from R&D relief, check that your activities and documentation still qualify.
