1. Choose your business type
Sole trader
Simplest option. You and the business are the same in law, so you are personally liable for debts. Register for Income Tax with Revenue.
Limited company (LTD)
A separate legal entity that limits personal liability. Must be registered with the Companies Registration Office (CRO) and file annual returns.
Partnership
Two or more people sharing ownership. Each partner pays tax on their share of profits.
Business name
If you trade under a name that isn't your own, register it as a business name with the CRO.
2. Register your business
Company registration
File online through CRO's CORE system. You need a company name, registered office in Ireland, at least one director and a company secretary.
EEA-resident director
A company needs at least one EEA-resident director, or a non-resident bond, or proof of a real economic link to Ireland.
Beneficial owners
After forming a company, register its beneficial owners on the RBO register within 5 months.
Business bank account
Open a separate business account — banks will ask for your CRO certificate and ID.
3. Register for tax
Revenue Online Service (ROS)
Register for Income Tax (sole trader) or Corporation Tax (company) and get your ROS access.
VAT
Register once your turnover goes over the VAT threshold (€42,500 for services, €85,000 for goods). You can register voluntarily below it.
Employer PAYE
If you hire staff, register as an employer before the first payday and report pay through PAYE Modernisation.
Preliminary tax
Self-employed people pay tax in advance each year — keep records and set money aside.
4. Funding & free support
Local Enterprise Offices (LEO)
Free mentoring, 'Start Your Own Business' courses and grants for small businesses in every county.
Enterprise Ireland
Support and investment for high-potential start-ups that plan to export and grow.
Microfinance Ireland
Small loans for start-ups that can't get bank credit.
Start-up tax reliefs
New companies may get relief from corporation tax in their first years, and investors may use EIIS relief.
5. If you are from outside the EU/EEA
You usually need permission to run a business in Ireland.
Start-up Entrepreneur Programme (STEP) — main route
For innovative start-ups that can grow and sell internationally. Needs €50,000 funding (€30,000 per extra founder) and a €350 fee. Not for retail, catering or personal services. Gives 2 years' residence at first.
Business Permission (Stamp 1) — limited
Still in the rules, but Irish Immigration no longer has an application page for it. Contact Immigration Service Delivery before relying on it.
Already living here?
Stamp 4, Stamp 5 and EU/EEA, UK or Swiss citizens can run a business with no extra permission. Most other stamps (1, 1G, 2, 3) can't.
