Selling a business is a major financial event that can shape an entrepreneur’s future. In the United Kingdom, capital gains tax (CGT) plays a crucial role in determining how much of the sale proceeds an owner keeps. Over the years, the rules around CGT, especially the concessionary rates for business sales, have changed significantly. These changes affect how business owners plan their exits and manage their wealth. This article explores the evolution of capital gains tax on business sales in the UK, focusing on the concessionary rates, the impact of recent changes, and practical advice for business owners.
What Is Capital Gains Tax and How Does It Apply to Business Sales?
Capital gains tax is a tax on the profit made when you sell or dispose of an asset that has increased in value. For business owners, this often means paying tax on the gain made from selling shares in their company or the business assets themselves.
In the UK, CGT rates depend on your total taxable income and the type of asset sold. For most assets, the rates are 10% or 20%, but business owners have historically benefited from lower rates under specific reliefs.
The Role of Entrepreneurs’ Relief (Now Business Asset Disposal Relief)
Entrepreneurs’ Relief (ER), renamed Business Asset Disposal Relief (BADR) in 2020, was introduced to encourage entrepreneurship by reducing the CGT rate on qualifying business disposals to 10%. This relief applied to gains up to a lifetime limit, which was initially set at £1 million but later increased.
The £10 Million Lifetime Limit
Until recently, business owners could claim BADR on up to £10 million of gains during their lifetime. This meant that if you sold your business or shares and your total gains were below this threshold, you would pay only 10% CGT on those gains instead of the higher standard rates.
This concessionary rate was a significant incentive for entrepreneurs, allowing them to keep more of their profits and reinvest or enjoy the rewards of their hard work.
Recent Changes to Capital Gains Tax on Business Sales
The UK government has been reviewing and adjusting CGT rules, including BADR, to raise revenue and address perceived inequalities in the tax system. These changes have created uncertainty and concern among business owners.
Reduction of the Lifetime Limit
One of the most impactful changes was the reduction of the BADR lifetime limit from £10 million to £1 million. This change means that business owners can now only claim the 10% rate on gains up to £1 million, with any gains above that taxed at the standard CGT rates.
Impact on Business Owners
This reduction affects many entrepreneurs who planned their business sales around the £10 million threshold. For example:
A business owner expecting to sell shares with a gain of £8 million would have paid 10% CGT on the entire amount under the old rules.
Now, they pay 10% on the first £1 million and 20% (or 28% for residential property) on the remaining £7 million, significantly increasing their tax bill.
Practical Examples of How CGT Changes Affect Business Sales
Example 1: Small Business Sale Under £1 Million Gain
Sarah owns a small business and plans to sell it for a gain of £800,000. Under the current BADR rules, she pays 10% CGT on the entire gain, resulting in a tax bill of £80,000.
Example 2: Medium Business Sale Over £1 Million Gain
John sells his business with a gain of £5 million. He pays 10% on the first £1 million (£100,000) and 20% on the remaining £4 million (£800,000), totaling £900,000 in CGT. Under the old rules, his tax would have been just £500,000.
Example 3: Large Business Sale Near the Old Limit
Emma sells her business with a gain of £9 million. She now faces a CGT bill of £1.6 million compared to £900,000 previously, nearly doubling her tax liability.
Strategies to Manage Capital Gains Tax on Business Sales
Business owners can take steps to reduce their CGT exposure or plan their sales more effectively.
Use of BADR: Ensure you meet all qualifying conditions for BADR, such as owning at least 5% of shares and voting rights.
Timing of Sale: Spread the sale over multiple tax years to use annual CGT exemptions.
Gifting Shares: Transfer shares to family members or trusts to use their CGT allowances.
Investing in SEIS/EIS: Use Seed Enterprise Investment Scheme or Enterprise Investment Scheme to defer or reduce CGT.
Professional Advice: Consult tax advisors to explore reliefs like rollover relief or holdover relief.
What Business Owners Should Know Going Forward
The landscape of capital gains tax on business sales is evolving. The reduction of the BADR lifetime limit signals a shift towards higher taxation on large business disposals. Business owners should:
Review their exit plans in light of current CGT rules.
Keep detailed records of business ownership and transactions.
Stay informed about potential future tax changes.
Seek professional advice early to structure sales tax-efficiently.
Selling a business involves more than just finding a buyer. Understanding how capital gains tax applies and adapting to changes in reliefs like Business Asset Disposal Relief can save significant amounts of money. While the reduction of the lifetime limit from £10 million to £1 million increases tax bills for many, careful planning and expert advice can help business owners protect their gains and achieve their financial goals. If you are considering selling your business, start by reviewing your CGT position and exploring all available options to make the most of your sale.
