The Chancellor, John Healey, has delivered the Autumn Budget 2026, announcing a range of tax changes and measures affecting businesses, employers and the self-employed.

While the Government has avoided widespread increases to the main business tax rates, there are several important changes that small business owners should be aware of. These include changes to Capital Gains Tax relief, increases in the National Minimum Wage, additional business rates support and new requirements for tax reporting.

Business Asset Disposal Relief – Important Changes for Business Owners

One of the most significant announcements concerns Business Asset Disposal Relief (BADR), which can reduce the Capital Gains Tax payable when business owners sell their business or shares in their company.

From 6 April 2027, the lifetime limit for qualifying gains will be reduced from £1 million to £500,000.

The reduced Capital Gains Tax rate of 18% will continue to apply to qualifying gains within the available lifetime allowance. Gains exceeding that limit will generally be subject to the normal Capital Gains Tax rates.

For business owners considering retirement or selling their company, this could result in a substantially higher tax bill.

Our advice: If you are considering selling your business, retiring or transferring your shares, it is worth reviewing your plans well before April 2027.

National Minimum Wage – Higher Employment Costs

The National Minimum Wage and National Living Wage will increase from 1 April 2027.

The new hourly rates will be:

• £13.21 for employees aged 21 and over.
• £11.27 for employees aged 18 to 20.
• £8.31 for employees aged 16 to 17 and eligible apprentices.

For a full-time employee aged 21 or over working 37.5 hours per week, the minimum annual salary will increase to approximately £25,760.

Although the headline rates of employers’ National Insurance have not been increased in this Budget, higher wages will also increase associated employment costs, including employer pension contributions.

Our advice: Businesses employing staff should review their wage budgets and consider the impact on profitability and cash flow.

Business Rates – Additional Relief for High Street Businesses

There is some welcome news for businesses operating in the retail, hospitality and leisure sectors.

From April 2027, the Government will increase the rateable value thresholds for Small Business Rate Relief for qualifying properties in England.

The threshold for 100% relief will increase from £12,000 to £18,000, with tapered relief available for qualifying properties with rateable values up to £21,000.

Qualifying businesses will also benefit from a two-year real-terms freeze on business rates bills.

Additional relief will be available for pubs, social clubs and qualifying live music venues.

These changes could provide meaningful savings for smaller shops, cafés, restaurants, salons and other qualifying high street businesses.

Corporation Tax and Business Investment

The existing structure remains in place, with a 19% small profits rate and a 25% main rate, subject to the usual thresholds, marginal relief and associated-company rules.

Full expensing will also continue for qualifying capital expenditure by companies, allowing businesses to obtain immediate tax relief on certain investments in plant and machinery.

Self-Employed Trading Allowance Increased

From 6 April 2027, the Income Tax trading allowance will increase from £1,000 to £3,000.

This will benefit individuals earning relatively small amounts from self-employment or other qualifying trading activities.

The change may be particularly helpful for people running small side businesses or undertaking occasional freelance work.

It is important to remember that the trading allowance is an alternative to deducting actual business expenses, rather than an additional allowance available on top of those expenses.

New Capital Gains Tax Relief for Entrepreneurs

The Chancellor has also announced a new Founders’ Relief, intended to encourage entrepreneurs to establish and grow innovative businesses in the UK.

From April 2027, qualifying founders of eligible high-growth businesses will be able to benefit from a reduced Capital Gains Tax rate of 10% on up to £10 million of lifetime gains.

This relief is aimed at a particular category of growing businesses and will not automatically apply to all company directors or shareholders.

The detailed eligibility conditions will be important in determining who can benefit.

VAT and Electronic Invoicing

There has been no increase in the standard rate of VAT, which remains at 20%.

However, the Government has confirmed plans to introduce mandatory electronic VAT invoicing from 1 April 2029.

Businesses will be required to issue VAT invoices in a specified electronic format, with further technical guidance expected before implementation.

Although the change is some years away, it represents another significant development in the move towards digital tax administration.

Businesses using modern accounting software should be well placed to adapt, although changes to existing invoicing procedures may be necessary.

Changes to Self Assessment Tax Payments

Another important announcement concerns the timing of Income Tax payments.

From April 2029, taxpayers who currently make Self Assessment payments on account will be required to make more regular payments towards their annual tax liabilities.

The intention is to bring tax payments closer to the period in which income is earned.

For sole traders and partners, this could mean a change to the way tax payments are budgeted throughout the year.

Further details will be needed before the full implications can be assessed.

Property Income – Higher Tax Rates for Landlords

Individuals receiving rental income will also be affected by an increase in the Income Tax rates applicable to property income.

From April 2027, these rates will rise by two percentage points across the relevant tax bands.

This could increase the tax burden on individuals who own residential or commercial investment properties personally.

Landlords should review their expected tax liabilities and consider the effect on the net income generated by their properties.

What Should Small Business Owners Do Now?

Although many of the changes will not take effect until April 2027 or later, there are several matters worth considering now.

Business owners approaching retirement should review the Capital Gains Tax implications of any planned sale. Employers should update their wage forecasts, while businesses occupying commercial premises should check their entitlement to business rates relief.

It is also sensible to review planned capital expenditure, future tax payments and the suitability of existing accounting systems.

Taking advice early can help businesses understand the financial impact of the changes and avoid unexpected tax liabilities.

Although some announcements will benefit smaller businesses, others could increase costs or create additional tax liabilities.

Businesses and employees can now claim more for business travel, following HMRC’s first mileage rate increase in 15 years.

HM Revenue & Customs (HMRC) has announced an increase to the Approved Mileage Allowance Payments (AMAPs) for employees and self-employed individuals using their own vehicles for business journeys. The change applies from 6 April 2026 and is backdated to the start of the current tax year.

The headline rate for cars and vans has increased from 45p to 55p per mile for the first 10,000 business miles travelled each tax year. The rate for mileage above 10,000 miles remains unchanged at 25p per mile.

New HMRC Mileage Rates for 2026/27

Vehicle	First 10,000 Business Miles	Over 10,000 Business Miles
Cars & Vans	55p per mile	25p per mile
Motorcycles	24p per mile	24p per mile
Bicycles	20p per mile	20p per mile

Employees carrying fellow employees on a qualifying business journey can also continue to claim an additional 5p per passenger per mile.

What Does This Mean?

The increase is designed to better reflect the rising costs of motoring, including fuel, maintenance, insurance and vehicle depreciation. It is the first increase to the standard mileage rate since 2011.

For employees who use their personal vehicles for work, the change could result in significantly higher tax-free mileage reimbursements. Businesses should also review their mileage policies and expense systems to ensure they are applying the updated rates.

From 6 April 2026, HMRC will require many UK taxpayers to submit quarterly updates of their income and expenses under the Making Tax Digital for Income Tax (MTD ITSA) rules.

This will replace the current single annual Self Assessment return with quarterly summary submissions made using compatible digital software, followed by a final year-end declaration.

To enable us to complete these submissions on your behalf, you will need to provide your income and expenditure details proactively on a quarterly basis with very short specific filing deadlines.

From 18 November 2025, all company directors and people with significant control (PSCs) will be legally required to verify their identity under the Economic Crime and Corporate Transparency Act 2023. This requirement is part of wider reforms to help prevent the misuse of UK companies.

Although not a deadline, more a “start-line” all returns to be filed after the above date will require this personal code to be submitted for all registered directors.

To do this start here Verify your identity for Companies House – GOV.UK

Once you have done this you will receive a personal code which you should keep secure, until such times as you may need that to submit accounts and returns to Registrar Of Companies

In the UK, if you sell certain assets (like property or shares) and make a profit (capital gain), you might need to pay Capital Gains Tax (CGT).

For some types of property, you must report and pay it separately and sooner—this is called a Real-Time Capital Gains Tax Return.

When do you need to file a Real-Time CGT Return?

You must file a real-time CGT return if:

1. You sell UK residential property that is not your main home (e.g., a rental property, holiday home, or second home).
2. You make a taxable capital gain (i.e., the profit is above your tax-free allowance, called the Annual Exempt Amount).
3. You owe CGT on the sale (e.g., because it isn’t covered by reliefs or allowances).

How soon must you report and pay?

• 60 days from the sale completion date
• You must calculate the CGT due and pay it at the same time as submitting the return.

What if you’re already filing a Self Assessment return?

• You still need to file a real-time CGT return if the property sale meets the criteria above.
• Later, you also report it in your Self Assessment to confirm the final tax amount (any overpayment or underpayment is adjusted then).

What types of property sales don’t need a real-time CGT return?

• If the property is your main home and qualifies for Private Residence Relief (so no tax is due).
• If your total capital gains in the tax year are below the Annual Exempt Amount (£6,000 for 2023/24).
• If you sell non-property assets like shares (these are reported in the normal Self Assessment).

What happens if you miss the deadline?

• Late filing penalties apply (starting from £100).
• Interest is charged on late tax payments.
