At a Glance

• Stamp Duty: Understand the tax implications of purchasing shares and property in the UK. Stamp duty is payable on the value of shares (0.5%) or property (SDLT rates from 0% to 17%). 

• Capital Gains Tax (CGT): Know how CGT affects both you and the seller, especially if the seller is eligible for Business Asset Disposal Relief (BADR), which can lower CGT rates. 

• Asset Purchase vs. Share Purchase: Decide between purchasing assets or shares. Asset purchases allow for capital allowances and might avoid liabilities, while share purchases might offer a smoother transition. 

• Tax Reliefs: Take advantage of reliefs like capital allowances, R&D tax credits, and the Patent Box regime to reduce your tax liabilities. 

• Inheritance Tax (IHT): Plan for business succession and future tax burdens, particularly if you are acquiring a family business. 

• The Importance of a Tax Advisor: Engage a tax advisor early to ensure tax efficiency, legal compliance, and better deal structuring. 
  

Why Use a Tax Guide to Buying a Business?

Buying a business is a major investment and one with significant tax consequences if not handled correctly. A detailed tax guide to buying a business helps you identify potential risks, access valuable reliefs, and structure the deal in a way that supports long-term growth. Whether it’s choosing between an asset or share purchase, understanding CGT implications, or managing stamp duty costs, this guide ensures you're well-informed at every step.

Stamp Duty and Its Impact on Your Purchase 

Stamp duty is one of the primary taxes to consider when buying a business. It applies differently depending on whether you're purchasing shares or property. 

• Stamp Duty on Share Purchases: If you're purchasing shares in a company, you’ll pay stamp duty at a rate of 0.5% on the transaction value or market value of the shares (whichever is higher). While this might seem straightforward, it can accumulate, especially for high-value transactions. 

• Stamp Duty Land Tax (SDLT): If the business you’re purchasing owns property or land, you may be liable for SDLT on the value of the land or property being transferred. SDLT rates can range from 0% to 17%, depending on the value and type of property. 
  

Tip: Work with us to determine the best approach to minimise stamp duty costs, particularly if the transaction includes high-value land or property. 

Capital Gains Tax (CGT) and Its Role in Business Acquisitions

When purchasing a business, the seller may be liable for Capital Gains Tax (CGT), and this could impact the final purchase price. 

• CGT on Share Purchases: In a share purchase, the seller is responsible for paying CGT on any capital gains made from the sale of their shares. This liability could be factored into the price you pay for the business. 

• CGT on Asset Purchases: For asset purchases, the seller may also face CGT on the sale of individual business assets, such as intellectual property or property. As the buyer, you’ll need to ensure the seller accounts for any CGT exposure when negotiating the price.  

Tip: If the seller* qualifies for Business Asset Disposal Relief (BADR), they may receive tax benefits, including reduced CGT rates. This can affect the asking price and should be factored into your decision-making.

Structuring the Purchase for Tax Efficiency

The structure of your transaction - whether an asset purchase or share purchase - can have significant tax implications. 

• Asset Purchase: If you choose to buy individual assets like stock, machinery, or intellectual property, you may be able to claim capital allowances on those assets. However, asset purchases often require negotiating contracts, transferring employees, and dealing with potential liabilities attached to those assets. 

• Share Purchase: In a share purchase, you acquire the entire business, including its assets, liabilities, contracts, and obligations. While this approach offers a smoother transition, it means assuming the company’s existing liabilities, which could be a potential risk. 
  

Tip: A tax advisor can help you choose the most tax-efficient structure based on the specific circumstances of the business you’re purchasing. 

Tax Reliefs and Incentives You Should Consider

Several tax reliefs and incentives are available to reduce the tax burden when purchasing a business. 

• Capital Allowances: If you buy tangible assets such as machinery or equipment, you can claim capital allowances on the cost of these assets. This can help reduce your taxable profits and lower your corporation tax liability. 

• Research & Development (R&D) Tax Credits: If the business you’re purchasing is involved in innovation or technological development, you may be eligible for R&D tax credits. These credits can provide cash back or reduce your tax liability based on qualifying expenditure on R&D activities. 

• Patent Box Relief: If the business holds patents or intellectual property, you may be able to claim Patent Box relief. This reduces the tax rate on profits derived from patented inventions. 
  

Tip: Ensure your tax advisor thoroughly assesses the business’s assets and activities to identify all available tax reliefs and credits that could be applied post-purchase. 

Inheritance Tax (IHT) Planning and Business Succession

Inheritance Tax (IHT) is often overlooked when buying a business, but it can become a key consideration, especially if you're purchasing a family-run business or a business with significant long-term planning involved. 

• Family Business Considerations: If you're purchasing a family business, IHT planning should be part of the overall transaction strategy. How you structure the deal can have lasting implications for tax efficiency and future wealth transfer. 

• Valuation and IHT: An accurate business valuation is crucial for both the purchase and future IHT planning. Properly valuing the business now ensures that you’re not hit with a hefty IHT bill later on. 
  

Tip: Plan ahead for IHT implications and consult a tax advisor for the most tax-efficient succession strategies to safeguard wealth for future generations. ‘Bespoke’ companies are something we specialise in. 

The Role of a Tax Advisor in the Buying Process

A tax advisor plays a critical role in the business acquisition process. Their expertise will help ensure the transaction is structured to minimise tax liabilities and maximise financial outcomes. 

Key tasks of a tax advisor include: 

• Advising on tax-efficient transaction structures (asset purchase vs. share purchase). 

• Identifying and maximising available tax reliefs and incentives. 

• Helping with capital gains tax and stamp duty planning. 

• Ensuring that the transaction complies with UK tax laws and regulations. 

• Assisting with the due diligence process and ensuring all documents are in favour. 

• Offering guidance on inheritance tax and long-term business succession planning. 
  

Tip: Involve a tax advisor as early as possible to ensure you make the best decisions at every step of the purchase process.
