Your after-incorporation checklist

You've got your certificate of incorporation. Here's what needs to happen next — and the deadlines that catch new companies out.

Updated October 2026 · General guidance, not legal or tax advice.

  1. Register beneficial owners (RBO) — within five months of incorporation.
  2. Register for corporation tax with Revenue through ROS eRegistration — you'll get a tax reference for the company.
  3. Register for VAT if turnover will exceed the thresholds (at the time of writing €42,500 for services / €85,000 for goods) — or voluntarily to reclaim VAT on set-up costs.
  4. Register as an employer (PREM) before paying anyone, including yourself as a director on payroll.
  5. Open a business bank account in the company's name — never mix company and personal money.
  6. Decide how you'll take payments — invoicing, payment links, online checkout or a card terminal. Rates and set-up support for new businesses differ a lot between providers, so compare.
  7. Get insurance — public liability, professional indemnity or employer's liability depending on your trade.
  8. Diary your first annual return (B1) — due six months after incorporation, then yearly. Late filing brings penalties and can cost you audit exemption.
  9. Keep statutory registers — members, directors and secretaries, minutes of meetings.

Frequently asked questions

When is the first annual return due for a new Irish company?

The first annual return date is six months after incorporation. After that, the annual return is due each year.

Do I need to register for VAT straight away?

Only if your turnover will exceed the VAT thresholds, but many new companies register voluntarily so they can reclaim VAT on start-up purchases. Ask your accountant.
