Selling a business is a significant financial decision — but it’s also a legal process that must be handled correctly. In the UK, selling a business involves more than just handing over the keys. You must meet legal obligations, prepare detailed documentation, and ensure you follow tax, employment, and compliance laws.
Whether you’re selling a small independent store or a growing enterprise, this guide outlines the legal requirements to sell a business in the UK — helping you avoid penalties, delays, or disputes. At SellAnyBiz.com, we make the process easier by connecting sellers with qualified buyers and providing essential support every step of the way.
Understand What Type of Sale You’re Making
Asset Sale vs Share Sale
The structure of the business sale affects your legal responsibilities and tax implications. There are two main types:
- Asset Sale: You sell specific assets of the business, like inventory, equipment, goodwill, and property. The buyer does not take on liabilities.
- Share Sale: You sell shares of the business (if it’s a limited company), and the buyer takes control of the entire business — including its debts, contracts, and obligations.
Why It Matters
In an asset sale, the seller may retain liabilities. In a share sale, the buyer assumes both assets and liabilities. Legal and financial advisors can help you choose the best structure for your goals.
Get Your Legal Documents Ready
Essential Legal Agreements for the Sale
Before marketing your business, make sure you have the correct legal documents prepared:
- Confidentiality Agreement (NDA) – Protects your business information when dealing with potential buyers.
- Heads of Terms – A non-binding outline of key sale terms such as price, payment method, and timeline.
- Sale and Purchase Agreement (SPA) – The final legally binding contract detailing the terms of the business sale.
- Disclosure Letter – A document highlighting known liabilities or issues in the business to avoid future disputes.
Don’t Skip This Step
Buyers expect clear and professional documentation. Working with a solicitor ensures these documents meet legal standards and protect your rights.
Conduct Due Diligence
What is Due Diligence?
Due diligence is the buyer’s investigation of your business before agreeing to the purchase. You’ll be asked to provide complete records and financial transparency.
What You’ll Need to Share
- Profit and loss accounts for the past 3–5 years
- Tax returns and VAT records
- Contracts with customers, suppliers, or landlords
- Intellectual property documents
- Staff contracts and payroll records
- Proof of licenses or permits
Having this ready streamlines the sale and builds buyer trust.
Inform Your Employees and Follow TUPE Rules
What is TUPE?
If employees will transfer with the business, the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE) will apply. TUPE protects employee rights during a business transfer.
What You Must Do
- Notify employees in writing
- Consult with employees or union reps
- Provide details of employment terms to the buyer
- Ensure continuity of employment contracts
Failure to comply can result in legal claims or fines.
Handle Your Tax Responsibilities
Taxes When Selling a Business
Selling a business can lead to various tax liabilities. It’s crucial to understand what’s required and how to minimise your tax burden.
Key Tax Considerations
- Capital Gains Tax (CGT) applies to profits from the sale.
- You may qualify for Business Asset Disposal Relief (formerly Entrepreneurs’ Relief), reducing CGT to 10%.
- Stamp Duty applies to share sales.
- VAT considerations may apply to asset sales.
Speak with an accountant or tax advisor to structure your sale efficiently.
Review Regulatory and Licensing Requirements
Transferring Licenses or Registrations
If your business operates in a regulated industry, such as food services, finance, or healthcare, licenses may need to be transferred to the buyer or reapplied for.
What to Check
- Food hygiene certifications
- Financial conduct licenses
- Local council permits
- Data protection registrations (if applicable)
Check with the relevant authority to ensure compliance.
Notify HMRC and Companies House
Keep Your Records Up to Date
You must notify the appropriate government bodies about the sale of your business. This is especially important if you’re selling a limited company.
Required Notifications
- Inform HMRC about cessation of trading, VAT deregistration, and payroll closure.
- Notify Companies House about changes to directors, shareholders, or company ownership.
- Submit final accounts and tax returns if winding down the company.
