What the 2025 Autumn Budget Means for UK Business Owners

The Autumn Budget has landed – or more accurately, leaked.

Thanks to the OBR accidentally publishing its report ahead of schedule, we had the chance to start reading through it before the Chancellor had even finished clearing her throat. It’s not often government paperwork arrives early…

Jokes aside, the Budget contains a series of subtle but significant shifts that directly affect UK business owners. While headlines will inevitably focus on personal taxes and welfare reform, the real story for SMEs and owner-managed companies is buried in the details.

Below is a business-focused breakdown of what’s changing, why it matters, and what owners, directors, buyers, and sellers should be thinking about next.

1. Dividends: Tax Is Rising

The Budget includes a 2-percentage-point increase across all dividend tax bands from April 2026, affecting all owner-managed companies that rely on dividends as a key method of profit extraction. This follows several years of frozen allowances and reduced dividend thresholds, further eroding the traditional “small salary + dividends” model.

What this means for business owners

• Your take-home income will fall, particularly if you distribute profits primarily via dividends.
• Companies with multiple shareholder-directors will experience a noticeable cumulative effect.
• It becomes increasingly important to review total reward, including salary, pension contributions, and benefits.
• Some businesses may consider retained profit strategies or reinvestment ahead of extraction.

For business buyers

• When analysing businesses where profits flow heavily to directors via dividends, expect lower post-tax returns.
• Adjust valuation models to reflect the higher tax drag on owner income.

2. Salary-Sacrifice Pensions Hit With a New NI Charge

A major under-the-radar change; National Insurance will now apply to salary-sacrificed pension contributions. For years, salary sacrifice has been one of the most tax-efficient remuneration tools for directors and senior staff. That advantage has now been partially removed.

Implications

• Director tax planning becomes more expensive – many owner-managers will effectively face a higher payroll tax burden.
• SMEs offering generous pension-via-sacrifice schemes will see increased employment costs.
• Expect accountants to recommend restructuring remuneration models before year-end.

Practical next steps

• Review all salary-sacrifice arrangements immediately.
• Remodel employee benefit costs for 2026 and beyond.
• For businesses being sold, update normalised EBITDA to reflect NI impacts on remuneration packages.

3. Employee Ownership Trust (EOT) Relief Tightened 

The Budget delivers one of the most significant changes to succession planning in years; capital gains tax relief on disposals to Employee Ownership Trusts will be cut from 100% to 50%. This does not scrap EOTs, but it removes their most powerful incentive to business owners.

Previously, owners selling to an EOT paid 0% CGT. Under the new rules, half of the gain becomes taxable, meaning many sellers will face an effective CGT rate of around 10% (assuming 20% CGT on the taxable portion). For many business owners, particularly those in professional services and owner-managed firms where EOTs surged in popularity, this is a meaningful shift.

Key points

• The EOT CGT advantage has been halved, making the route notably less generous.
• Sellers considering an EOT will need updated modelling of net proceeds, deal structure, and timing.
• Situations where an EOT was “almost as attractive” as a trade sale may now fall clearly in favour of open-market disposal.

For business advisers and buyers

• Expect more owners to pivot back toward traditional trade-sale routes or MBOs.
• EOT-heavy sectors (architects, agencies, manufacturing, consulting) may experience an increased supply of businesses coming to market.
• Buyers should be alert to owners reconsidering EOT plans and returning to competitive sale processes.

4. No New Changes to Business Asset Disposal Relief (BADR)

A relief to many. While no further changes were announced, it’s crucial for owners to remember that BADR is still moving from 14% to 18% in April next year. This remains a significant shift that materially reduces the attractiveness of selling at the 10% rate on the first £1m of lifetime gains (which had already been cut from £10m in 2020).

What this means in practice

• There is no new change today, but sellers from April 2026 will still face an increased tax bill.
• Owners considering a sale should factor the 18% rate into their planning.
• Where feasible, some sellers may consider accelerating their exit to avoid the uplift.

5. Corporation Tax: Writing Down Allowances Reduced

Another technical but important change in this Budget is the reduction in Writing-Down Allowances (WDAs) on capital expenditure. The main pool WDA, which applies to most plant and machinery, will fall from 18% to 15%, while the special rate pool for integral features and long-life assets will drop from 6% to 4%. For capital-intensive businesses, this change increases taxable profits by slowing the rate at which investment can be written off.

Manufacturing firms, engineering companies, construction businesses, automotive operators, and fleet-heavy sectors will feel this most acutely. In practice, it lengthens the payback period on new equipment and reduces the near-term tax benefit of investing in plant, machinery, or upgrades. At a time when financing costs are already elevated and margins are under pressure, this shift makes future capital expenditure decisions more complex and, in some cases, less attractive.

Impact on valuations

• Buyers must adjust future tax liabilities upward.
• Multiples may soften in asset-heavy sectors.
• Businesses preparing for sale should ensure CAPEX assumptions reflect slower relief.

It’s worth noting that while WDAs are being reduced, certain qualifying investments may continue to benefit from enhanced first-year allowances (e.g. 40% FYA on main-rate assets). These do not offset the broader reduction in writing-down allowances but may offer limited relief for growth-focused or CAPEX-intensive firms making strategic investments. Eligibility will depend heavily on asset type and scheme qualification.

6. Profitability Pressures: OBR Confirms Lower Returns & Slower Growth

The OBR forecasts that business profits will decline in 2025 before beginning a gradual recovery. More importantly, the real rate of return on capital, a key measure of underlying business profitability, is projected to fall to around 10.75% in 2026, down from 12.5% in 2022. This downward shift reflects a range of structural and cyclical pressures across the economy. Wage growth remains elevated, productivity continues to stagnate, and borrowing conditions are still tight. Inflationary pressures remain embedded in supply chains and operating costs. At the same time, many businesses have delayed investment decisions over the past two years, creating a backlog of capital expenditure that is becoming harder to finance or justify.

Together, these factors reinforce a challenging environment for UK SMEs. Higher costs, slower growth, and weaker investment incentives mean many firms will struggle to expand margins. For sectors with naturally low pricing power, absorbing cost increases without eroding profitability will be particularly difficult.

Impact for owners

• Margins are likely to remain squeezed. Businesses with limited ability to increase prices will feel the pressure most, meaning owners must be realistic about medium-term performance and consider proactive efficiency measures.
• Labour-intensive sectors will also feel the impact of rising wage floors, including the latest National Living Wage increase.

Impact for buyers

• Lower profitability forecasts raise perceived risk, which will affect discount rates and deal structures. More cautious valuations should be expected.

7. Business Investment Forecast Falls Again

The OBR has once again downgraded expectations for business investment; hardly surprising given persistent low confidence and high borrowing costs. Businesses in manufacturing, logistics, construction, care, and hospitality may find it harder to justify long-delayed investments in fleets, machinery, and infrastructure.

For many SMEs, this means higher financing costs, extended payback periods, and increased operational risk. Buyers evaluating businesses with ageing assets or significant CAPEX backlogs may apply downward pressure to valuations or seek more conservative deal terms. However, tech-enabled and scale-up SMEs may benefit from targeted support schemes such as enhanced investor reliefs, though access and eligibility remain sector-dependent.

8. Frozen Tax Thresholds: Fiscal Drag Continues to Hurt Consumers & SMEs

The government’s extended freeze on personal tax thresholds will pull an additional 780,000 people into basic-rate tax, 920,000 into higher-rate, and 4,000 into additional-rate tax by 2029-30. A process economists politely refer to as fiscal drag, where everyone else might simply call “a tax rise by stealth”. This freeze quietly reshapes spending patterns across the SME economy.

Impact on SMEs:

• Consumers have less disposable income
• Wage expectations remain high
• PAYE-drawing directors are taxed more heavily
• Demand recovery in discretionary sectors will be slow

9. Likely Pressure Ahead for Business Rates

While business rates were not directly changed, the Budget highlighted mounting financial pressure on local authorities with significant increases in SEND (Special Educational Needs and Disabilities) provision costs. Historically, when local authority costs rise and funding does not, business rates follow.

Some industry commentary suggests that future business rate reforms may offer targeted support for smaller high-street, hospitality, or leisure operators, while larger commercial properties could face higher liabilities. However, the Budget provides limited clarity, and local authority funding pressures still point toward upward pressure overall.

What Business Owners Should Do Now

Now is the time for business owners to take stock; the changes mentioned reshape how profits are extracted and how businesses fund growth. Forecasts should be updated to reflect higher tax drag and constrained consumer spending, and CAPEX plans should be revisited with more scrutiny than ever.

Anyone considering selling their business should re-examine valuation expectations. Lower profitability forecasts and a higher long-term tax burden will influence buyer appetite and deal structure. Timing also matters, as with BADR rising to 18% next year, sellers should model scenarios to understand how this affects net proceeds. Succession planning deserves a fresh look too; while EOTs remain viable, the removal of the full CGT exemption means the financial calculation has shifted.
