What is LLC (Limited Liability Company)?

An LLC, or limited liability company, is a US business structure that protects its owners from personal liability for the business's debts. There is no UK LLC: the UK equivalent is the private limited company (Ltd), and the closest UK cousin to an LLC is the limited liability partnership (LLP).

Example

A UK consultant signs a contract with a US client who calls its own business an LLC. The consultant trades through a UK Ltd and does not need an LLC of their own.

How LLC (Limited Liability Company) Works in Practice

An LLC is a limited liability company, a structure created under US state law. It gives its owners, called members, limited personal liability, so their own assets are generally protected from the business's debts. It is popular in the US because it is simple to run and, by default, the profits pass through to the owners and are taxed on their personal returns.

The UK has no company type called an LLC. The closest equivalent in everyday use is the private limited company, usually written Ltd. A Ltd is a separate legal entity owned by shareholders and run by directors, it pays Corporation Tax on its profits, and the owners are taxed on salary and dividends they take out. Its liability protection is similar in spirit to an LLC.

The UK structure that looks most like an LLC in how profits flow is the limited liability partnership, or LLP. An LLP gives members limited liability but is taxed as a partnership, so profits are taxed on the members personally. It is mainly used by professional firms. A Ltd and an LLP are both registered at Companies House.

If you are a UK founder trading with US clients, you generally do not need to form a US LLC. Your UK Ltd can contract with US customers. US clients may ask you for a tax form confirming you are not a US taxpayer, usually from the W-8 series. If you plan to hire, sell or raise money in the US, take advice on whether a US entity helps.

Step by Step

A UK founder who wants limited liability registers a Ltd with Companies House, gets a certificate of incorporation, registers for Corporation Tax and keeps statutory records. The company files annual accounts and a confirmation statement.

If you want partnership style taxation with limited liability, an LLP may suit, although it carries its own filing duties. Sole traders keep things simplest but have no liability protection.

When dealing with a US LLC as a customer or supplier, treat it like any other business: agree terms, issue invoices and keep records. Cross border tax and VAT questions are worth checking when amounts are significant.

Practical Tips

  • Use a UK Ltd as your default structure unless you have a clear reason for a US entity
  • Ask a US client which tax form they need before the first payment
  • Keep your company records separate from personal finances to preserve limited liability
  • Take professional advice before setting up any cross border structure

Common Mistakes to Avoid

  • Assuming a UK business can register as an LLC, which is not a UK company type
  • Forming a US LLC when a UK Ltd would do, adding cost and filings for no benefit
  • Ignoring US tax form requests from clients, which can lead to withholding on payments
  • Confusing an LLC with an LLP, which are different structures in different countries
