Companies House Northern Ireland

One of the first things you’ll need to do when setting up a new business in Northern Ireland is register it with Companies House.

Headquartered in Belfast, Companies House is the official body responsible for incorporating and dissolving limited companies. It keeps a register of company information, and makes this available to the public. Companies House in Northern Ireland is sponsored by the Department for Business and Trade.²

Company register Northern Ireland

Just before you register at Companies House, you’ll need to decide on a type of legal entity for your new business. There are a few different business structures to choose from, including sole trader, partnership, limited liability partnership (LLP) and limited liability company (Ltd). We’ll run through each of these legal structures in more detail below.

For each legal structure type listed below add what it is, how it works and the relevant requirements, liability and tax obligations related.

Sole trader³

A sole trader is a structure for just one person running their own business. This person is solely liable for any debts, but it also means that they will have full control over their business. It’s the simplest type of business structure available, and it’s also possible to set up as a sole trader without having to pay any registration fees with Companies House.

Sole traders must keep records and accounts, complete annual tax returns and pay income tax and National Insurance.

Partnership⁴

A partnership is a structure designed for two or more people running the business together. They share ownership as well as profits and liability.

There are a few different types of business partnership in Northern Ireland

The first is an ordinary partnership. This is where the partnership has no legal existence separate from the partners. So, if a partner dies, resigns or goes bankrupt, the partnership will need to be dissolved. However, the business itself can continue.

Ordinary partnerships need to register with HMRC.

There are also limited partnerships. This is where the business is owned by a mix of ordinary and limited partners. The latter’s liability is limited in proportion to the amount of money they have invested in the business.

Limited partnerships must register at Companies House, who will inform HMRC in order for tax records to be set up. This company type doesn’t usually need to file accounts or annual returns.

The third type of partnership is a limited liability partnership (LLPs), which we’ll look at next.

Limited liability partnership (LLP)⁴

An LLP is a corporate entity, although it’s taxed as a partnership. This business type must have two designated members, all of whom have limited liability.

LLPs must register with Companies House in Northern Ireland, send an annual return and file accounts. Companies House will inform HMRC of registration, and tax records will be set up.

Limited liability company (Ltd)

The last type of business entity, and a common choice, is a limited liability company.

A limited company is separate from its owners, meaning that its finances are kept completely separate. This kind of business will typically have shareholders, who receive shares in the company in return for the capital they put in. Shareholders will have ownership rights and liabilities according to the value of their investment.

Limited companies must be registered at Companies House, and must have at least one member and one director. The company must file annual returns and accounts, and inform HMRC that it exists and whether it is liable for Corporation Tax, VAT, PAYE for employers and other taxes.⁵

Open a Wise Business account and you can manage your company’s finances in 40+ currencies. You’ll be able to pay suppliers and staff in euros and British pounds, as well as receiving payments in multiple currencies.

You can even automate payments using the powerful Wise API to save even more time. See how it works here in our case study.

Wise payments are fast and secure (even for large amounts). Best of all, you’ll only pay low, transparent fees and always get the mid-market exchange rate.

This is the rate that banks use to buy and sell currency, and is widely considered the fairest rate you can get. When banks carry out currency conversions on behalf of customers, they usually add a mark-up or margin to the exchange rate. This makes it more expensive for your business, as less of your money reaches your recipient.

It’s quick and easy to open a Wise Business account, with a fully digital application, verification and on-boarding process. Check out the requirements here.
