The UK Government’s Autumn Budget takes place on Wednesday 28 October 2026, making it one of the most important dates in the business calendar this autumn.
For businesses, the Budget could influence everything from employment costs and investment decisions to taxation, business rates and consumer demand.
At the time of writing, the detailed measures have not been announced. That means businesses should be careful about acting on speculation. However, the economic backdrop gives some indication of the issues that are likely to be closely watched when Chancellor John Healey delivers his Budget.
The Government has said the Budget will be based on fiscal discipline and meeting its fiscal rules, while also providing businesses and households with greater stability to plan for the future.
For business owners, the most useful approach is therefore not to try to predict the Budget, but to identify the areas where change could have the greatest effect.
Tax remains a key concern
Tax is likely to be one of the biggest areas of interest.
Businesses will be watching closely for any changes affecting:
- Corporation Tax
- Employer National Insurance
- Business rates
- Capital allowances
- Employment costs
- Dividend taxation
- Capital Gains Tax
- VAT
- Tax reliefs and investment incentives
The Government’s June Tax Update already established a programme of measures described as simplifying, modernising and improving fairness within the tax system. Some measures involve consultations and future changes, so businesses should not assume that the current position will necessarily remain unchanged.
The pressure on public finances
The Chancellor is entering the Budget with significant pressure on the public finances.
Recent reporting indicates that public-sector borrowing in August was substantially above expectations, increasing pressure on the Government’s fiscal position ahead of the Budget. The figures reported by the Financial Times showed borrowing of £18.3 billion for the month, £3.5 billion above the Office for Budget Responsibility’s forecast.
Businesses should therefore recognise that there may be limited room for large-scale tax reductions or spending increases.
This is one reason why companies should avoid making major decisions based on hoped-for Budget announcements.
Business costs remain a concern
The economic environment remains challenging.
The latest ONS Business Insights and Conditions Survey found that 29% of trading businesses cited economic uncertainty as a challenge, while cost of labour was the most reported challenge among businesses with 10 or more employees, at 37%.
The British Chambers of Commerce has also highlighted continued cost pressures.
Its September forecast expects UK GDP growth of only 1% in both 2026 and 2027, while business investment is forecast to fall by 0.2% in 2026.
This places considerable importance on measures that could affect the cost of employing people, operating premises and investing in the business.
Business rates and energy costs
Business rates remain an important issue for many companies, particularly those operating from physical premises.
The BCC has called for measures to reduce energy and business-rate pressures ahead of the Budget. Its proposals include reducing business-rate multipliers and providing greater support towards energy costs. These are proposals from the business organisation, not Government policy, but they demonstrate the issues currently being raised by the business community.
Retailers, hospitality businesses and other high-street companies will therefore be watching the Budget particularly closely.
Investment and allowances
Another important area is investment.
Businesses need to know whether the tax system encourages them to invest in equipment, technology, premises and productivity improvements.
The latest ONS figures show that UK business investment increased in the second quarter of 2026, but the BCC’s surveys suggest investment intentions remain weak.
That makes the treatment of investment in the Budget particularly relevant.
If businesses receive greater certainty around capital allowances or other incentives, it could influence investment decisions. Conversely, uncertainty about future tax treatment can encourage companies to delay expenditure.
What should businesses do before 28 October?
The best approach is preparation rather than speculation.
Businesses should review their current position and identify decisions that may be affected by Budget announcements.
For example:
- Are you planning major investment?
Understand the financial case independently of any possible tax relief. - Are you recruiting?
Calculate the full employment cost rather than focusing solely on salary. - Are you planning to sell or restructure the business?
Take professional advice before making decisions that could have tax consequences. - Are you reliant on business rates or energy costs?
Build realistic scenarios into your cash-flow forecasts. - Do you have sufficient cash reserves?
Uncertainty is easier to manage when the business has adequate working capital.
Budget Day is not the end of the process
One common mistake is to treat Budget Day as the moment when every question is answered.
In reality, Budgets frequently contain consultations, policy announcements, draft legislation and measures that take effect at different dates.
Businesses therefore need to distinguish between:
- Measures announced immediately
- Measures beginning later
- Consultation proposals
- Changes requiring legislation
- Longer-term Government ambitions
The practical implications may not become clear until the detail is published.
Prepare for several possible outcomes
Businesses do not need to predict what the Chancellor will announce.
Instead, they can prepare three simple scenarios:
- No major change:
What happens to your business if current costs and tax rules continue? - Higher costs:
What happens if employment, energy or tax costs increase? - Supportive measures:
What opportunities would you pursue if the Budget provides additional incentives?
This approach can help management make better decisions without relying on speculation.
Looking beyond the Budget
The Autumn Budget will be important, but it will not remove the underlying challenges facing UK businesses.
Companies will continue to deal with changing technology, labour costs, consumer demand, international trade and regulatory requirements.
The businesses best placed to respond will be those with good financial information and a clear understanding of their costs.
The message for October is therefore simple: watch the Budget, but prepare your business independently of it.
That way, whatever is announced on 28 October, the business will be in a stronger position to respond.
