Partnerships and LLPs Explained Simply

Thinking about starting a business with others? Choosing between a traditional partnership and a Limited Liability Partnership (LLP) is one of the most important early decisions you’ll make. This guide breaks down exactly what each structure means in UK law, how they work in practice, their pros and cons, tax implications, legal requirements, and what to watch out for. By the end, you’ll know which option (if either) is right for your business—and how to avoid the common pitfalls that trip up so many new partnerships.

A partnership, in the UK context, is a straightforward business structure where two or more people share ownership and responsibility for a business. It’s governed by the Partnership Act 1890. Unlike a limited company, a traditional partnership is not a separate legal entity from its partners. This means that the partners themselves are personally responsible for the business’s debts and obligations.

One of the main appeals of setting up as a partnership is its simplicity. There’s no need to register the partnership with Companies House (though you must register for tax with HMRC), and the administration is lighter compared to limited companies. Each partner is self-employed and taxed individually through Self Assessment, with their share of profits, losses, and tax allowances.

However, the lack of legal separation between the business and its owners makes traditional partnerships risky. If the partnership cannot pay its debts, creditors can pursue the personal assets of any or all partners. Also, each partner is ‘jointly and severally’ liable for the actions of the others. This means that if one partner incurs debt or is negligent, all partners are on the hook.

• No separate legal personality – the partners and the business are legally the same
• Each partner is taxed as an individual on their share of profits
• No Companies House registration required, but must register with HMRC for tax
• All partners are personally liable for business debts
• Joint and several liability applies to all partners

A Limited Liability Partnership (LLP) is a modern business structure created by the Limited Liability Partnerships Act 2000. It combines elements of both partnerships and limited companies. An LLP is a separate legal entity from its members, meaning the LLP itself can own property, enter contracts, and be sued. The key feature is that its members (partners) have limited liability. Their personal assets are usually protected if the business fails, provided they haven’t given personal guarantees or acted fraudulently.

To form an LLP, you must register with Companies House. At least two designated members are required, and they take on legal responsibilities for filing annual accounts and returns. LLPs are particularly popular among professional practices—such as law firms, accountancy firms, and consultancies—where partners want both the flexibility of a partnership and some liability protection.

Unlike limited companies, LLPs are taxed as partnerships: profits are divided among members, who then pay tax as self-employed individuals. However, the LLP must comply with some of the same regulatory and reporting requirements as limited companies, including annual accounts and confirmation statements.

• Separate legal personality – the LLP exists independently of its members
• Limited liability for members (except in cases of fraud or wrongful trading)
• Must register with Companies House and comply with filing requirements
• Members taxed individually on their share of profits
• Popular with professional services and joint ventures

Both partnerships and LLPs are ‘tax transparent’. This means HMRC does not tax the business itself—profits are divided among the partners or members, who then report their share on their own Self Assessment tax returns. Each partner is responsible for paying Income Tax and Class 2 and Class 4 National Insurance contributions on their share.

The partnership or LLP must submit a partnership tax return (SA800) to HMRC each year, showing the total income, expenses, and how profits are split. Each partner/member is also responsible for submitting their own Self Assessment return. Profit shares do not have to match capital contributions or time spent—how profits are split should be detailed in the partnership or LLP agreement.

Unlike limited companies, there’s no corporation tax for partnerships or LLPs. Partners/members also aren’t employees, so there’s no PAYE on their drawings, but you must register as an employer if you have staff. One frequent mistake is failing to set aside enough for tax, as profits can be taxed even if not physically withdrawn from the business.

To set up a traditional partnership, you must register the business and each partner with HMRC for Self Assessment. There’s no requirement to register with Companies House, but you should agree on a business name and check it’s not already in use. For LLPs, you must register with Companies House, file an incorporation document, and pay a registration fee (currently £40 for postal, £12 online).

It is strongly recommended—though not legally required—to draw up a written partnership or LLP agreement. This document should lay out how profits are split, responsibilities, what happens if someone leaves, and dispute resolution. Without an agreement, the Partnership Act 1890 or the default LLP rules apply, which may not be suitable for your business.

You’ll also need to consider whether to register for VAT (if turnover exceeds £85,000), set up a business bank account, and register as an employer with HMRC if you’ll have staff. For regulated industries, you may need additional licences or approvals.

• Check if your business name infringes any trademarks
• Register for VAT if turnover exceeds £85,000 (or voluntarily)
• Consider professional indemnity insurance to protect against claims
• Appoint at least two designated members for LLPs (they have extra responsibilities)
• Prepare to file annual accounts and returns for LLPs

The decision between a traditional partnership and an LLP comes down to a few core questions: How much risk are you willing to take? How much administrative burden can you handle? And what are your growth ambitions? Traditional partnerships are less regulated and easier to set up, but the lack of liability protection is a major concern for many.

LLPs, on the other hand, are more complex to run, with mandatory filing at Companies House and stricter record-keeping. However, the limited liability protects members’ personal assets if the business runs into trouble (unless you’ve signed personal guarantees or acted recklessly). LLPs also have more credibility with certain clients and lenders, particularly in professional services.

Consider also the ease of bringing in new members, transferring ownership, or winding up the business. LLPs can make these processes smoother, as the entity continues regardless of changes in membership. Traditional partnerships automatically dissolve if a partner dies or leaves, unless otherwise agreed.

• Traditional partnerships suit low-risk, low-complexity businesses with strong trust between partners
• LLPs are ideal for professional firms and businesses wanting limited liability
• LLPs require more admin, but offer enhanced protection and credibility
• Think about long-term growth and succession—LLPs are more flexible

Traditional partnerships have relatively light ongoing admin. You must keep accurate business records, submit a partnership tax return (SA800), and ensure each partner files their Self Assessment tax return. No annual accounts are required by law, but it’s wise to keep full accounts for internal use and potential HMRC checks.

LLPs have much heavier compliance obligations. You must file annual accounts and a confirmation statement with Companies House (even if dormant), keep statutory registers, notify Companies House of changes in membership, and comply with anti-money laundering rules if in a regulated sector. Failing to file accounts can result in fines (from £150 to £1,500 depending on lateness) and, after persistent non-compliance, striking off the LLP.

Both structures must comply with other UK regulations: data protection (ICO registration if you process personal data), health and safety (HSE), and employment law if you have staff. You’ll need to register for VAT once turnover hits £85,000 and may need to operate a PAYE scheme for employees. It’s common for new LLP members to misunderstand their tax status—they are not employees, even if they draw a regular amount each month.

• LLPs must disclose accounts on the public record at Companies House
• Designated members of LLPs are legally responsible for filings and compliance
• Partnerships don’t have to file accounts publicly, but should keep detailed records
• Both structures must file an annual partnership tax return (SA800) with HMRC
• Failure to comply with filing can result in fines and even business closure

Many business owners underestimate the risks of traditional partnerships. It’s a common misconception that you’re only liable for your own actions—actually, each partner is jointly and severally liable for all partnership debts and actions. This means your personal assets are on the line for mistakes or debts incurred by your partners, even if you weren’t involved.

Another regular pitfall is failing to create a clear, robust partnership or LLP agreement. Verbal agreements or default rules rarely suit a growing business and can cause chaos if someone wants to leave, falls ill, dies, or there’s a dispute. Make sure you spell out profit splits, decision-making processes, contributions, and exit procedures in writing, and review the agreement regularly.

Tax confusion is also rife. New partners or LLP members might assume they’re employees if they get a regular payment, but for tax purposes they are self-employed. This affects how you pay tax, claim expenses, and pay National Insurance. If in doubt, seek advice from a qualified accountant or business adviser before setting up, especially if you’re planning a complex profit-sharing arrangement or bringing in corporate members.

• Don’t assume your liability is limited in a traditional partnership – it isn’t
• Never skip a written partnership or LLP agreement
• Understand the tax treatment – you’re self-employed, not an employee
• Set aside money for tax on profits, not just drawings
• Check insurance requirements, especially for professional indemnity
