Frequently asked questions

How do I register a company in Mayo?

The process is the same nationwide: you file Form A1 and a constitution with the Companies Registration Office (CRO), usually online. A formation agent or accountant in Mayo can prepare and file everything for you, typically within a day or two, with the CRO processing it in around 5–10 working days.

How much does company formation cost in Mayo?

The CRO online fee is €50 at the time of writing. Professional packages from formation agents and accountants serving Mayo typically range from about €150 to €450 including that fee, depending on whether a secretary, registered office or tax registration is included.

Can I register as a sole trader in Mayo instead?

Yes. Sole traders register with Revenue rather than the CRO, which is free. Many businesses in Castlebar and across Mayo start as sole traders and incorporate once profits grow — your matched accountant can tell you which suits you.

Does the Local Enterprise Office help new businesses in Mayo?

Mayo is served by Local Enterprise Office Mayo. Local Enterprise Offices run Start Your Own Business courses, mentoring and grant schemes for small businesses. They don't register companies for you, but they're well worth contacting alongside your formation partner.
