What we see in Castlebar
Mayo's business base is dominated by small owner-managed companies and sole traders, often in tourism, trades and agriculture. For businesses at this scale the questions that matter are the unglamorous ones: whether to register for VAT at all, how much to set aside for preliminary tax, and whether the company structure is earning its cost.
Whatever your sector, the engagement works the same way: a fixed monthly fee agreed in advance, a named chartered accountant assigned at onboarding, and every enquiry answered within four business hours.

Questions Castlebar businesses ask
- Do you have an office in Castlebar?
- No. Our office is at Marina House, Clarence Street, Dún Laoghaire, Co. Dublin. We serve Castlebar businesses entirely online — secure document portal, cloud accounting and video calls — which is what keeps the fee fixed and lower than a local high-street practice.

- Can I switch to you from my current Castlebar accountant?
- Yes, and it is routine. We write to your existing accountant for professional clearance and the handover records, and we handle the transfer. The best time to move is shortly after a year end, but it can be done at any point.
- Are you chartered accountants?
- Yes. Finlay Mulligan & Co. are Chartered Accountants, regulated by Chartered Accountants Ireland. We are not a bookkeeping agency, and the person on your account is a qualified accountant.
