Every business begins with an idea, but one of the earliest and most consequential decisions a founder will make is how that idea is structured.
This is not simply a question of registration or formality. The chosen structure determines who bears risk, how profits are taxed, how decisions are made, how investment is raised, and how value is ultimately realised on exit.
In practice, we often see founders treat structure as a secondary consideration i.e. something to be addressed once the business gains traction. By that stage, however, early decisions can become embedded, and restructuring can trigger tax consequences, legal complexity, and avoidable cost.
The correct approach is to align structure with strategy from the outset, while retaining flexibility to evolve as the business grows.
Below is a detailed overview of the principal UK business structures, together with both advantages and limitations of each
- Sole Trader
Overview
A sole trader operates as an individual carrying on business in their own name or a trading name. There is no incorporation process and no distinction between the individual and the business.
Legal position
The business does not have separate legal personality. As a result, the individual is personally liable for all debts, contractual obligations, and liabilities, including claims in tort.
Tax treatment
Profits are taxed as income under self-assessment, subject to income tax and National Insurance Contributions.
Advantages
- Minimal setup and administrative burden
- Complete control over decision-making
- Direct access to profits without dividend restrictions
- Flexibility to commence and cease trading quickly
Disadvantages
- Unlimited liability, exposing personal assets (including property and savings)
- No separation of business and personal risk
- Limited ability to raise external finance or equity investment
- Reduced perceived credibility with counterparties
- No continuity independent of the individual
Commercial insight
Sole trader structures are often appropriate for testing viability, but they are rarely suitable where there is meaningful contractual exposure, regulatory risk, or growth ambition.
- General Partnership
Overview
A general partnership arises where two or more persons carry on business in common with a view to profit. It can arise expressly or by conduct, regardless of whether a formal agreement is in place.
Legal framework
Governed primarily by the Partnership Act 1890, which applies default provisions unless displaced by a partnership agreement.
Legal position
There is generally no separate legal personality (in England & Wales). Each Partner acts as an agent of the firm, and partners are jointly and severally liable for the obligations of the partnership.
Advantages
- Relatively simple to establish
- Flexible internal arrangements (if properly documented)
- Pooling of capital, expertise, and responsibility
- Tax transparency (profits taxed in the hands of partners)
Disadvantages
- Unlimited liability, including for the acts and omissions of other partners
- Significant risk where one partner binds the firm without authority
- Default statutory provisions may not reflect commercial intention
- Potential for disputes in absence of a robust partnership agreement
- Limited scalability and investment options
Commercial insight
Partnerships are frequently used where there is a high degree of trust between founders, but they carry material risk if governance, decision-making, and exit provisions are not clearly documented.
- Private Limited Company (Ltd)
Overview
A private company limited by shares is incorporated under the Companies Act 2006 and exists as a separate legal entity distinct from its shareholders and directors.
Legal position
- The company can contract, own assets, and incur liabilities in its own name
- Shareholders’ liability is generally limited to the amount unpaid on their shares
- Directors owe statutory duties under sections 171–177 of the Companies Act 2006
Tax treatment
- Profits are subject to corporation tax
- Shareholders are taxed on dividends and/or salary
Advantages
- Limited liability protection, subject to exceptions (e.g. personal guarantees, wrongful trading under the Insolvency Act 1986)
- Clear ownership structure through shares
- Ability to raise capital through equity issuance or investment rounds
- Enhanced credibility with investors, lenders, and counterparties
- Structured governance and decision-making framework
- Greater continuity and transferability of ownership
Disadvantages
- Ongoing compliance obligations (accounts, confirmation statements, statutory registers)
- Public disclosure of certain information at Companies House
- Directors’ duties and potential personal exposure for breach
- Formal processes required for decision-making and distributions
- Potential tax inefficiencies depending on extraction strategy
Commercial insight
For most growth-oriented businesses, the limited company structure is the default vehicle, particularly where there is any intention to raise external investment, scale operations, or pursue an exit.
However, the detail within the structure share classes, shareholder agreements, and governance arrangements—is often more important than the structure itself.
- Limited Liability Partnership (LLP)
Overview
An LLP is a corporate body with separate legal personality, created under the Limited Liability Partnerships Act 2000.
It combines elements of a partnership (internal flexibility and tax transparency) with features of a company (limited liability and separate entity status).
Legal position
- The LLP can contract and hold assets in its own name
- Members benefit from limited liability, subject to wrongful trading and personal wrongdoing
- Internal arrangements are governed by an LLP agreement
Tax treatment
- Typically treated as tax transparent, with profits taxed as income in the hands of members
Advantages
- Limited liability for members
- Flexibility in profit-sharing and management structures
- No requirement for share capital
- Familiar structure for professional services firms
Disadvantages
- Less suited to equity investment and venture capital structures
- Public filing requirements similar to companies
- Potential complexity in drafting effective LLP agreements
- Perception may vary depending on industry
Commercial insight
LLPs are particularly effective where businesses prioritise profit extraction and internal flexibility, rather than retained growth or external equity funding.
- Group Structures and Holding Companies
Overview
A group structure typically involves a holding company owning one or more subsidiary companies, each of which carries out distinct functions (e.g. trading, asset holding, IP ownership).
Legal position
Each entity within the group retains separate legal personality, allowing liabilities and assets to be ring-fenced.
Advantages
- Segregation of risk between trading and asset-owning entities
- Protection of key assets (e.g. intellectual property, property)
- Flexibility in structuring investment and exit (e.g. share sale at subsidiary level)
- Potential tax efficiencies (subject to structuring and applicable reliefs)
- Facilitates joint ventures and partial disposals
Disadvantages
- Increased administrative and compliance burden across multiple entities
- Greater complexity in governance and intercompany arrangements
- Higher professional and advisory costs
- Requires careful implementation to avoid unintended tax or legal consequences
Commercial insight
Group structures are rarely necessary at inception but become highly relevant as businesses scale, particularly where there is diversification, investment activity, or exit planning.
Strategic Considerations When Choosing a Structure
The appropriate structure will depend on a combination of:
- Risk profile – level of contractual, regulatory, or operational exposure
- Funding strategy – self-funded vs external investment
- Tax objectives – income extraction vs retained growth
- Control and governance – number of founders and decision-making dynamics
- Exit strategy – trade sale, investment, succession, or long-term hold
Crucially, structure should be viewed as dynamic rather than static. What is appropriate at inception may require refinement as the business evolves.
Johnson & Boon Insight
In our experience, structural issues rarely arise because founders chose an obviously unsuitable vehicle. More often, they arise because:
- The structure was chosen without reference to future funding or exit
- Ownership arrangements were not properly documented
- Tax and legal advice were not aligned
- Governance was not clearly defined at the outset
Addressing these issues later can involve restructuring, renegotiation, and potential tax exposure—all of which can be avoided with early, strategic advice.
Choosing the right structure is not about complexity—it is about alignment.
If you are establishing or restructuring a business, taking advice at the outset can ensure your legal framework supports growth, protects value, and preserves flexibility for the future.
