Need clarity on the 2025 Autumn Budget?
The Autumn Budget 2025 predictions are already taking shape as we head towards 26 November, a date the Treasury has confirmed for the Chancellor’s next fiscal statement. If you want support planning for the year ahead, the right accounting services can help you stay compliant and confident.
This year’s Budget lands in a tough economic climate. The latest figures from the Office for National Statistics show public sector net debt at around 95 per cent of GDP, one of the highest levels in decades, while borrowing in the first half of the year exceeded the Office for Budget Responsibility’s forecast due to weak growth and higher spending.
Rachel Reeves is still bound by Labour’s core fiscal rule that public debt must fall as a share of GDP by the end of the Parliament. At the same time, Labour has pledged not to raise Income Tax, National Insurance or VAT for working people, a promise repeated in official manifestos and HM Treasury summaries.
These competing pressures mean the Chancellor may look elsewhere for revenue. Analysts at several respected institutions, including the Institute for Government and the Institute for Fiscal Studies, have highlighted that reliefs, allowances and property-related taxes are the most likely areas to change if the government wants to raise money without breaching headline tax pledges.
It is important to remember that nothing is confirmed until the Chancellor delivers her speech. Speculation is helpful for planning, but you should not make irreversible decisions based solely on rumour.
In this guide you’ll learn:
- What credible Budget predictions suggest for income tax, dividends and National Insurance
- Whether Corporation Tax or VAT rules could shift for small businesses
- How property, pensions and investment taxes may change
- What owners, directors and sole traders can do to prepare without panicking

When is the 2025 Autumn Budget?
The Autumn Budget will be delivered on 26 November 2025, as confirmed by the HM Treasury in a formal announcement.
The timing matters because the speech will be accompanied by updated forecasts from the Office for Budget Responsibility (OBR), setting the backdrop for any tax or spending decisions.
The UK’s public finances are under strain. According to the Office for National Statistics (ONS) data the public sector net debt (PSND) stood at 95.3 % of GDP in September 2025.
Working-within these tight constraints, the government is bound by the fiscal rule requiring debt to fall as a share of GDP. Politically, the Labour Party has also pledged not to raise Income Tax, National Insurance or VAT for working people, further narrowing the Chancellor’s options.
Because of all this, many analysts expect the Chancellor to target less visible levers of taxation such as reliefs, allowances or property-related taxes rather than headline tax-rate hikes.
Nothing is fixed until the Budget speech, so businesses and directors should treat all speculation as planning prompts, not actionable certainty.
What is coming in the Autumn Budget 2025?
Below are the most credible Autumn Budget 2025 predictions that could affect small businesses, company directors and landlords who operate through a company. Each prediction includes a likelihood rating based on recent government statements, fiscal rules and analysis from independent institutions.
Income Tax threshold freezes
Likelihood: High
According to analysis from the House of Commons Library, the freeze on Income Tax thresholds until April 2028 is already locked in. Several fiscal commentators note that extending this freeze to 2030 would raise significant revenue without breaching Labour’s pledge not to increase Income Tax for working people. This would pull more directors into higher tax bands over time and increase the overall tax burden on salaries.
What this means for your business: If Income Tax thresholds stay frozen, more of your director’s salary may fall into the higher rates over time. This is the fiscal drag effect flagged by the Institute for Fiscal Studies, and it affects anyone who takes part of their income through PAYE. If you want a refresher on how the bands currently work, see our guide on UK tax brackets.
National Insurance changes for directors and partners
Likelihood: Medium
According to commentary from the Institute for Fiscal Studies, the government has been examining ways to widen the National Insurance base. The IFS notes that applying employer National Insurance to partnership profits has been explored as a potential revenue source. This would directly affect LLP partners and some professional firms, especially those using partnership structures for tax efficiency.
What this means for your business: If National Insurance rules tighten for partnerships or non-PAYE income, LLPs and service companies could see higher personal tax costs. If you want a refresher on how the bands currently work, see our guide on UK tax brackets.
Directors paid through a mix of salary and dividends may need to review their balance ahead of the new tax year.
Dividend tax changes
Likelihood: Medium
The GOV.UK guidance on dividend tax confirms that the dividend allowance fell to £500 this year. Analysts at several economic institutions have argued that a further reduction or a rise in dividend tax rates would raise revenue without breaching Labour’s “no income tax rise for working people” pledge. This would impact directors who rely on dividends rather than salary.
What this means for your business: If the dividend allowance is reduced again or dividend tax rates rise, profit extraction becomes more expensive. Directors who rely on a low-salary, high-dividend structure should keep an eye on this. For an overview of how dividends currently work, read our explainer on what a dividend is.
Corporation Tax adjustments
Likelihood: Low to Medium
The current 25 per cent main rate is published on GOV.UK. According to recent commentary from the Institute for Government, the government is unlikely to increase the headline rate again because it could damage competitiveness.
However, tightening reliefs and allowances remains possible. These adjustments would affect investment decisions for small companies and could reduce tax efficiency for directors drawing profits.
What this means for your business: The main rate is expected to remain at 25 per cent, but reliefs and allowances may change. Adjustments to capital allowances, R&D rules or the small profits rate can still shift your final bill. If you want a quick breakdown of how the current system works, see our guide on how to pay Corporation Tax.
Companies using marginal relief should pay close attention to any tweaks that affect bands or thresholds. Even subtle changes can alter the effective rate for companies earning between £50,000 and £250,000.
VAT threshold or policy changes
Likelihood: Medium
The Office for Budget Responsibility has highlighted for several years that the UK’s VAT threshold is unusually high internationally. OBR analysis shows that this creates a distortion in business behaviour, often called the “bunching” problem. Freezing the threshold or adjusting it slightly is viewed by analysts as a credible option for raising revenue. Owners near the £90,000 threshold would be most affected.
What this means for your business: Businesses near the £90,000 VAT registration threshold should monitor any changes the Chancellor announces. The OBR has repeatedly highlighted that the frozen threshold distorts business behaviour, so movement here is possible. If you want to prepare in advance, our guide on registering for VAT explains how the process works and what to expect.
Capital Gains Tax changes
Likelihood: Medium
According to official guidance on GOV.UK, the CGT annual exempt amount has already been reduced to £3,000. Several tax experts note that CGT has been one of the easiest levers for recent Chancellors to adjust quickly. Any rise in CGT rates or further cuts to allowances would impact directors holding shares, as well as landlords operating through companies.
What this means for your business: Changes to Capital Gains Tax would affect directors selling shares, property or business assets. Any reduction to the allowance or increase to the rate would increase the tax due on disposals.

Property-related taxes for company landlords
Likelihood: Medium
Analysis from the Institute for Government confirms that policymakers have been exploring options for taxing high-value property more effectively. These include upper council tax bands, revaluation of property values and mansion-tax style mechanisms. Directors who hold investment properties through companies may face higher annual charges if these reforms progress.
What this means for your business: These possible reforms would affect landlords holding property inside a company, particularly those with high-value assets. Annual charges may rise, meaning directors should review cash flow, rental profitability and tax position if these changes move forward.
If you want to understand how company property decisions work today, read our guide to buying property through a limited company.
Pension tax changes for directors
Likelihood: Medium
The rules for pension tax relief are set out on GOV.UK. According to discussion papers cited by the Institute for Fiscal Studies, limiting higher-rate pension tax relief or capping salary sacrifice has been examined as a way to increase revenue. Directors who use pension contributions to extract profits tax-efficiently should watch for any movement here.
What this means for your business: If higher-rate pension tax relief is restricted or salary sacrifice rules change, directors may need to rethink how they build long-term savings. Pension contributions remain one of the most efficient ways to extract profit from a company, but the Chancellor may tighten the rules to boost revenue.
ISA limit changes
Likelihood: Medium
The rules on ISA allowances are published on GOV.UK. Analysts have suggested that cutting the Cash ISA limit could encourage more investment into UK-listed companies. This would affect directors who use ISAs alongside dividend and pension strategies.
What this means for your business: If the ISA allowance is reduced, it affects how directors save outside their business. ISAs are often used to build personal reserves while keeping company cash optimised for operations, so any cut to limits may shift how much income directors extract each year.
Other Budget rumours (limited relevance to business owners)
These measures have appeared in news coverage but do not meaningfully affect most companies or directors:
- Tourism tax
- Milkshake sugar-tax extension
- Taxi VAT changes
- Gambling duty
- Cycle to Work scheme caps
- Fuel duty rises
If you run a small business or take income as a director, these are the areas most likely to affect your tax bill, so it is worth keeping a close eye on November’s announcements. We’ll write a separate blog on the day outlining the changes.
How to prepare for the Autumn Budget without panicking
You do not need to overhaul your finances based on predictions. A few simple steps will put you in a strong position once the Chancellor confirms the final measures.
- Review how you pay yourself. Look at your current mix of salary, dividends and pension contributions. This helps you understand where any changes may hit hardest.
- Update your business forecasts. Make sure your cash flow, profit projections and expected tax bills are accurate. This gives you room to adjust quickly if thresholds or allowances move.
- Delay big decisions if you can. If you are planning large withdrawals, selling assets or changing your company structure, it may be worth waiting until the Budget speech.
- Keep your records clean. Up to date bookkeeping makes it easier to respond to changes in Corporation Tax, VAT or reliefs.
- Avoid making moves based purely on rumours. Speculation can be useful for planning, but acting early without confirmed policy can create unnecessary costs.

FAQs on the 2025 Autumn Budget
When is the Autumn Budget 2025?
The Autumn Budget will be delivered on 26 November 2025. The Chancellor will speak shortly after Prime Minister’s Questions, which usually places the announcement early in the afternoon.
What time does the Autumn Budget usually start?
Budgets typically begin around 12.30pm. The Office for Budget Responsibility’s forecasts are published at the same time, which helps explain the impact of the measures.
Will the Autumn Budget increase Corporation Tax for small businesses?
A rise in the main Corporation Tax rate is unlikely, but adjustments to reliefs and allowances may still increase your effective rate. Small businesses using marginal relief should pay attention to any changes to thresholds or qualifying rules.
How could the Autumn Budget affect my director salary and dividends?
If thresholds remain frozen or dividend taxes increase, the tax you pay on salary and profit extraction could rise. Directors who use a mix of salary and dividends will need to check how the final measures affect their take home income.
Are VAT thresholds expected to change?
There is speculation that the VAT registration threshold may be frozen for longer or adjusted slightly. Any movement here would affect businesses close to the £90,000 limit and may bring more companies into VAT registration.
Could the Autumn Budget change pension tax relief for directors?
It is possible the Chancellor may look at higher-rate pension tax relief or salary sacrifice rules. This would affect directors who use pension contributions as part of their profit extraction strategy.
Should I delay major financial decisions until after the Budget?
If you can, it may be sensible to wait. Selling assets, withdrawing large sums or changing your company structure is easier once you know the confirmed measures. Acting early based on rumours can create unnecessary risk.
