Steps to start a business in Northern Ireland

Starting a business in Northern Ireland follows the same broad process as the rest of the UK, with useful regional support available along the way. Here are the key steps:

• Research your business idea and target customers: Identify your target market, check whether there's demand for your product or service and research what competitors already offer.
• Write a simple business plan: Set out your revenue model, startup costs, target customers and how you plan to cover expenses in the early months. nibusinessinfo offers a free business plan template to get you started.¹
• Choose a business structure: Decide between sole trader, partnership or limited company. Each carries different rules on liability, tax and how you register the business.
• Register with HMRC or Companies House: Sole traders register for Self Assessment with HMRC,² and limited companies register with Companies House.³
• Check licences, permissions and insurance: Some business activities require a licence or permit before you can legally trade.⁴ Employers' liability insurance is a legal requirement for most businesses that hire staff.⁵
• Set up business records and accounting: Record all income and expenses from day one. Accurate records make Self Assessment, VAT returns and cash flow management easier to handle.
• Check your tax, VAT and business rates responsibilities: Sole traders file a Self Assessment return. Limited companies pay Corporation Tax and register with HMRC after incorporation.⁶
• Find local business support and funding: nibusinessinfo's My New Business covers business structure, naming, managing money, premises, staff and legal responsibilities.¹ Go Succeed offers free tailored advice through Northern Ireland's 11 local councils.⁷
• Open a business bank account: Keep business and personal finances separate from the start.
• Start trading and review your finances regularly: Monitor income, expenses and cash flow each month so you can spot issues early and adjust quickly.

Choosing your business structure

Choosing the right structure affects how you pay tax, your personal liability and your reporting responsibilities. Most businesses register as either a sole trader or a limited company, though other structures are available.

Sole trader

A sole trader is the simplest structure to set up. You run the business yourself, keep all profits after tax and make all business decisions. There are no registration fees with Companies House, but you're personally responsible for any business debts.⁶

You must register for Self Assessment with HMRC, keep records of income and expenses and pay Income Tax and National Insurance on your profits.

Business partnership

A partnership suits two or more people running a business together. Partners share profits, decisions and liability, and each partner pays Income Tax on their share of profits through Self Assessment.⁸

Partners are personally liable for business debts, including those caused by other partners. There are different types of partnership, including ordinary and limited partnerships.

Limited liability partnership (LLP)

An LLP combines elements of a partnership and a limited company. Members have limited liability, so personal assets are protected beyond what they've invested in the business. LLPs must register with Companies House, file annual accounts and have at least two designated members.⁹

Limited company

A limited company is legally separate from its owners, which limits personal liability for business debts. Limited companies must register with Companies House, file annual accounts and a confirmation statement, and register with HMRC for Corporation Tax.³

Social enterprise

A social enterprise is a business with a social, community or environmental mission. It's not a legal structure in itself. Social enterprises typically register as a limited company, CIC or another recognised structure depending on their goals.⁸

If you're unsure which structure fits your situation, nibusinessinfo has guidance on choosing a business structure for Northern Ireland founders.¹

Registering your business in Northern Ireland

How you register your business depends on the structure you choose. Here's what each route involves.

Sole trader

Registering as a sole trader is free and done through HMRC, not Companies House. You need to register for Self Assessment, keep records of all income and expenses and pay Income Tax and National Insurance on your profits.⁶

Limited company

To register a limited company, you must incorporate with Companies House. The digital incorporation fee is currently £100.¹⁰ You'll need to choose a company name, appoint at least one director and provide details of shareholders and people with significant control (PSCs).

Companies House identity verification

From 18 November 2025, identity verification became a legal requirement for all new directors and PSCs. New directors must verify their identity before appointment or incorporation. New PSCs must provide their personal verification code to Companies House within 14 days of appointment.¹¹

You can verify directly through GOV.UK One Login using an accepted photo ID. Once verified, you receive a personal code to use across all Companies House roles.

Partnership and LLP

Ordinary partnerships register with HMRC for Self Assessment. Limited partnerships and LLPs must also register with Companies House.⁹ If you're unsure which registration route applies to your business, nibusinessinfo has step-by-step guidance for Northern Ireland founders.¹

The loan is a personal loan for business purposes, available over one to five years at a fixed rate of 7.5% per annum.¹⁶ Applicants must be 18 or over, a UK resident and starting a new business or trading for up to 60 months.

Funding and loan availability can change quickly. Always check the official provider page before applying. Support availability can also vary by council area and eligibility.

Tax, VAT and business rates

Tax responsibilities vary depending on your business structure, turnover, profits, premises and whether you employ staff. Here's a high-level overview of what to check.

Self Assessment

Sole traders and most partners must register for Self Assessment with HMRC and file a tax return each year.⁶ You'll pay Income Tax and National Insurance on your profits.

Corporation Tax

Limited companies pay Corporation Tax on profits. The main rate is 25% for profits over £250,000, with a small profits rate of 19% for companies with profits of £50,000 or less. Companies with profits between £50,000 and £250,000 pay the main rate reduced by marginal relief.¹⁸

VAT

You must register for VAT if your taxable turnover exceeds £90,000 in any 12-month period, or if you expect to.¹⁹ Voluntary registration is also available below the threshold.

PAYE

If your business hires staff, you must register as an employer with HMRC before the first payday.²⁰ This also applies if you're the sole director of a limited company and pay yourself a salary.

Business rates

Business rates in Northern Ireland are a tax on non-domestic properties such as offices, factories and shops.²¹ nibusinessinfo has guidance on how non-domestic rates work, how to pay them and what rate reliefs may be available.

Tax responsibilities depend on your business structure, turnover, profits, premises and whether you employ staff. Check GOV.UK or HMRC guidance, or speak to an accountant if you're unsure.

Licences, permissions and insurance

Before trading, check whether your business activity needs a licence, permit, registration or insurance. Requirements vary by sector and local council area.

Some business activities need a licence or permit from your local council or a government body before you can legally trade. Common examples include food businesses, alcohol sales, taxis, childcare, beauty treatments, street trading and waste handling.⁴

Use the GOV.UK licence finder to check which licences apply to your business activity and location. Your local council can also advise on sector-specific requirements in Northern Ireland.

If you hire staff, employers' liability insurance is a legal requirement for most businesses.⁵ Some sectors also require professional indemnity or public liability insurance. Check GOV.UK or speak to a broker to confirm what applies to your business.

Open a business bank account

Keeping business and personal finances separate makes bookkeeping cleaner, simplifies tax records and gives you a clearer picture of cash flow. nibusinessinfo has guidance on choosing a business bank account in Northern Ireland and the key factors to consider.

Limited companies need a separate business account because the company is a legally separate entity.²² Sole traders are not legally required to have one, but a dedicated account makes managing income, expenses and tax returns much easier.

When comparing accounts, look at:

• Monthly fees and transaction costs
• Cash deposit options
• Accounting software integrations
• International payment support
• Customer service and online banking features

Northern Ireland businesses can compare high street banks, local banks such as Danske Bank, Ulster Bank, Bank of Ireland and AIB, as well as online providers.

If your business handles overseas payments or works with international clients, Wise Business is worth comparing alongside traditional optionsfor multi-currency management and international transfers.
