What Is an LLP? Limited Liability Partnerships Explained

The limited liability partnership, or LLP, is the structure that tries to give you the best of both worlds. It keeps the flexibility and tax treatment of a partnership — partners sharing profits and running things their own way — while adding the crucial protection of a company: limited liability. That combination is why LLPs are so popular with professional firms such as solicitors, accountants and architects, where partners want to work together without being personally ruined by a colleague's mistake. This guide explains what an LLP is, how its members are taxed, and how it stacks up against an ordinary partnership and a limited company. This is general information, not legal or tax advice.

What an LLP is

A limited liability partnership is a business structure that combines the flexibility of a partnership with the limited liability of a company. Introduced in the UK in 2000, it was designed precisely to solve the problem at the heart of an ordinary partnership: that partners are personally liable for the business's debts and for each other's actions.

The defining features of an LLP are:

• It is a separate legal entity — distinct from its members, able to own property, sign contracts and sue or be sued in its own name.
• Its members have limited liability — they are generally not personally responsible for the LLP's debts beyond what they have agreed to contribute.
• It is run by members (the equivalent of partners), with the internal arrangements set out in an LLP agreement rather than imposed by a rigid company structure.
• It must have at least two members, and at least two of them must be "designated members" with extra responsibilities for filing.

In short, an LLP behaves like a partnership day to day but shields its members the way a company shields its shareholders. It sits naturally alongside the other structures covered in our guide to business partnerships.

Limited liability: the key benefit

The whole point of an LLP is in the name. In an ordinary partnership, liability is unlimited and joint — if the business fails, creditors can pursue the partners' personal assets, and one partner can be liable for another's actions. An LLP removes that exposure.

With an LLP:

• A member's liability is generally limited to the amount they have invested or agreed to contribute.
• Personal assets — homes, savings — are protected from most business debts.
• One member is not automatically liable for the negligence or debts of another.

Limited liability is protection, not a force field. Members can still be liable for their own professional negligence, for fraud, or where they have given a personal guarantee. It shields you from the business's general debts, not from your own wrongdoing.

For firms whose partners give professional advice — where a single error could lead to a large claim — this protection is invaluable, which explains why so many law and accountancy practices operate as LLPs.

How an LLP is taxed

Here the LLP keeps its partnership character: it is tax-transparent. The LLP itself does not pay Corporation Tax. Instead, like an ordinary partnership, its profits flow through to the members, who are each taxed individually.

The mechanics are:

1. The LLP works out its total profit for the year.
2. Profit is shared between the members according to their agreement.
3. Each member pays Income Tax and National Insurance on their share through Self Assessment, taxed broadly as self-employed individuals.
4. The LLP files its own partnership tax return to show how profits were divided, but pays no tax itself.

This is a significant point of difference from a limited company. A company is taxed in its own right on its profits, and the owners are then taxed separately on salary and dividends they extract. An LLP has just one layer of tax, at the member level. Whether that is more or less efficient than a company depends on profit levels and how money is taken out — exactly the kind of comparison we explore in sole trader vs limited company. Members will each need to handle their own Self Assessment tax return and pay National Insurance on their share.

Disclosure: the trade-off

The protection of limited liability comes at a price: public disclosure. Because an LLP is a registered entity with limited liability, the law requires it to be more transparent than a private, unlimited partnership.

An LLP must:

• Register at Companies House when it is formed.
• File annual accounts at Companies House, which become public.
• File a confirmation statement each year confirming its details — the same filing companies must make, covered in our guide to the confirmation statement.
• Keep its registered details, members and people with significant control up to date.

This is more administration than an ordinary partnership, which files nothing at Companies House and keeps its accounts private. For many firms the disclosure is a fair exchange for limited liability — and the public register can even lend credibility — but it is a genuine difference to weigh. The filing duties broadly mirror those you take on when you register a UK company.

LLP vs ordinary partnership vs company

It helps to see the three side by side:

The LLP occupies a clear middle ground. Against an ordinary partnership, it adds limited liability and separate legal status — at the cost of public filing. Against a limited company, it keeps tax transparency and flexible internal governance, avoiding the company's two-layer tax and rigid director-shareholder roles. The choice usually turns on liability, tax position and how the owners want to share profits and make decisions.

Setting up and running an LLP

To set up an LLP, you broadly:

1. Choose at least two members, designating at least two as designated members.
2. Pick a name that complies with the rules and ends with LLP or Limited Liability Partnership.
3. Have a registered office address.
4. Register (incorporate) the LLP at Companies House.
5. Put an LLP agreement in place setting out profit shares, decision-making and what happens when members join or leave.

The LLP agreement is just as important as a partnership agreement. Without one, default statutory rules apply, which may not match what the members intend — for instance over profit sharing or decision-making. Getting it drafted properly at the outset, while everyone is aligned, prevents disputes later. Once running, the LLP must keep proper records, file its accounts and confirmation statement on time, and ensure each member meets their personal tax obligations.

The bottom line

An LLP combines the flexibility of a partnership with the limited liability of a company. It is a separate legal entity registered at Companies House, its members are protected from most business debts, and it is taxed transparently — members pay Income Tax and National Insurance on their share of profits while the LLP itself pays no Corporation Tax. The trade-off for that protection is public disclosure: an LLP must file accounts and a confirmation statement. Popular with professional firms, it sits between an ordinary partnership and a limited company. Put a solid LLP agreement in place, keep up with filings, and treat GOV.UK and Companies House as the authoritative sources.
