Budget 2025: What UK Small Business Owners Really Need To Know

Budget announcements rarely feel designed with small business owners in mind.

Budget 2025 is no different.

There are a few headline wins for individuals, but when you zoom in on small companies, employers and directors, the overall direction is clear: more tax, more pressure on payroll and more complexity when you eventually exit.

This guide breaks down the key areas that actually matter if you run a small business, work as a director or own property in your own name.

We’ll look at:

• Income tax and dividend tax rises

• National Minimum Wage increases

• Salary sacrifice changes

• Employee Ownership Trust (EOT) changes

• The so-called “mansion tax”

• Electric vehicle mileage charges

And, most importantly, what they might mean for you in the real world.

1. Income Tax & Dividend Tax Rises And Frozen Thresholds

Income tax on salary and property income

From April 2027, the main income tax rates on savings and personally owned property income are set to increase:

• Basic rate: 20% ➜ 22%

• Higher rate: 40% ➜ 42%

If you hold rental properties in your own name, this is a direct hit to the net income you keep after tax.

Even a 2% rise adds up over a full year of salary or rental income, especially if both you and a partner are drawing at or near the basic rate threshold.

Dividend tax rises

Dividends are also getting more expensive from April 2026.

Basic rate dividend tax is rising by 2 percentage points – for example from 8.75% to 10.75% at basic rate.

That means:

• A solo director taking around £50k out of their company each year could see roughly £750 extra tax

• A married couple both drawing around £50k from the same business could see approximately £1,500 extra tax between them

Nothing dramatic on its own, but enough that it needs to be built into cashflow forecasts, personal tax planning and dividend strategies.

Threshold freezes – the “stealth tax”

On top of the headline rate changes, income tax thresholds are being frozen until 2031.

Student loan repayment thresholds are also frozen.

In practice that means:

• Wages go up

• Tax thresholds do not

• More of your income is taxed at higher rates

• Student loan repayments rise as a percentage of your pay

This is why people call it a “stealth tax”; no obvious rate rise, but more of your income gets dragged into higher bands.

📌 What to do now

• Build the extra 2% into your forecasts from April 2026

• Review your salary vs dividend mix with your accountant

• If you’re close to higher rate bands, think about splitting income between spouses where appropriate and allowable

2. National Minimum Wage Increases – Especially Painful For Hospitality & Retail

From April 2026, National Minimum Wage is set to rise to:

• £12.71 per hour for 21+ (≈4% rise)

• £10.45 per hour for 18–20 (≈8.5% rise)

• £8.00 per hour for 16–17 (≈6% rise)

For higher-paying sectors, this might barely register. But if you run a small:

• Coffee shop

• Bar or pub

• Restaurant

• Leisure or tourism business

• Retail shop

…then this is significant.

It’s not just the headline wage either. For each pound of extra salary, you also face:

• Employer’s National Insurance

• Pension contributions

• Potential knock-on effects on pay scales for more experienced staff

A quick example

Imagine an independent coffee shop:

• Turnover: £200,000

• Wage bill: £100,000

An 8% rise in wage cost could easily add £8,000+ before employer NIC and pensions, and potentially nearer £10,000+ when everything is factored in.

At a 50% gross margin, that might mean you need £20,000+ extra turnover just to stand still.

📌 What to do now

• Model your 2026/27 wage bill with the new rates

• Stress-test your pricing and margins

• Consider where you can improve efficiency and productivity without simply cutting hours and burning out your team

3. Salary Sacrifice & Pensions – Less Efficient At Higher Levels

Salary sacrifice has been a popular tool for directors and employees who want to:

• Boost pension contributions

• Save income tax and National Insurance

• Keep net take-home reasonably healthy

Under Budget 2025 changes, there will now be National Insurance relief only on the first £2,000 of pension contributions via salary sacrifice.

Above that level, NI will be due, which:

• Narrows the tax advantage at higher contribution levels

• Makes planning a bit more fiddly for owner-directors using salary sacrifice as a main extraction route

• Slightly reduces the incentive to push large amounts into pensions via salary sacrifice

📌 What to do now

• Review your pension contribution strategy if you’re using salary sacrifice heavily

• Factor the reduced NIC saving into your overall remuneration planning

• Speak to both your accountant and an independent financial adviser before making changes

4. Employee Ownership Trusts (EOTs) – Still Attractive, But No Longer Tax-Free

For many years, an Employee Ownership Trust (EOT) has been one of the most attractive ways to sell a business:

• The trust acquires the shares

• Employees become the beneficiaries

• Historically, qualifying disposals could be taxed at 0% Capital Gains Tax

Budget 2025 changes that.

What’s changed?

• EOTs no longer offer 100% CGT relief

• Instead, 50% of the gain is exempt, and 50% is taxed at CGT rates (up to 24%)

So if you sold a business for £1,000,000:

• Before: potentially £0 CGT

• Now: £500,000 taxable at up to 24% CGT (~£120k–£125k in tax)

Is an EOT still worth it?

In many cases: yes. EOTs still offer:

• A structured way to pass the business to your team

• Continuity for clients and staff

• Cultural and legacy benefits

• More control over how the business is run after your exit compared to some third-party buyers

But the pure tax advantage has definitely been reduced.

Business Asset Disposal Relief also rising

If you plan to sell to a third party instead, Business Asset Disposal Relief (formerly Entrepreneurs’ Relief) is rising:

• Previously 10%

• Going up to 18% from April 2026

So whichever way you look at it, exiting your business is getting more expensive from a tax perspective.

📌 What to do now

• If you’re thinking of exiting in the next 3–5 years, start planning now

• • Trade sale

  • Management buyout

  • Employee Ownership Trust

    Run comparisons between:

• Think about more than tax: culture, continuity, risk and your own long-term role

5. “Mansion Tax” For Properties Over £2 Million

From April 2028 (if implemented), there will be a new tax on properties valued over £2 million – often labelled a “mansion tax”. This raises a few key questions:

• Who will be caught?

  Not just huge estates – many London and South-East homes could creep over £2m, especially where values have risen over decades.

• How will value be decided?

  We don’t yet have the full detail, but it is likely to lean on valuation bandings similar to council tax and business rates, which may trigger appeals and challenges near the threshold.

• What about long-term homeowners?

  Someone who bought a property for £1m thirty years ago and now finds it valued at £2.5m hasn’t “realised” that gain, but could still fall into the scope.

📌 What to do now

• If your property is likely to be near or above £2m, keep an eye on the detail as we approach 2028

• Don’t panic or rush decisions now – policies at that distance can and do change

6. Electric Vehicles – Per-Mile Charges From 2028

From April 2028 (if implemented), the Budget proposes a new per-mile levy on electric and hybrid vehicles:

• 3p per mile for fully electric vehicles

• 1.5p per mile for hybrids

As an EV driver, I’ve crunched some rough numbers:

• 100-mile round trip in an EV:

  • Electricity cost: maybe £3–£4 (depending on tariffs and efficiency)

  • New levy: £3

  • Total: £6–£7

Compare that with a similar trip in a petrol or diesel car, which might easily cost £20+ in fuel. So EVs will likely still be cheaper to run overall, but the “free ride” on road tax is ending.

📌 What to do now

• • Benefit-in-kind rates

  • Charging costs

  • Future per-mile levies

    If you’re considering an EV for your business, factor in:

• Build per-mile costs into your expense policies if you reimburse staff for business mileage

Final Thoughts: What Should Small Business Owners Focus On?

There’s a lot of noise in any Budget. Not all of it requires immediate action. Here’s a simple priority list:

1. Short-term (next 12–18 months)

   • Understand how wage rises might hit your margins

   • Review salary vs dividends and plan for the 2026 tax rises

   • Revisit salary sacrifice and pension contribution strategies

2. Medium-term (2–3 years)

   • If you’re planning an exit, start exploring EOT vs trade sale vs other routes now

   • If you’re close to higher tax bands, revisit your overall remuneration structure

3. Long-term (3+ years)

   • Keep an eye on the mansion tax and EV levies – but don’t make drastic decisions based on 2028 rules that may change

   • Focus on building a profitable, resilient business – that will matter more than any single Budget in the long run

As always, the detail of how this affects you will depend on your specific circumstances, so this is general guidance, not personal advice.

If in doubt, sit down with your accountant, run the numbers and build a plan that works for you.
