Company Secretary Requirements in Ireland for a Single Director Company
Staxo Team, 2026-09-16
One of the attractions of the Irish private company limited by shares (LTD) is that it can have a single director. What catches many founders out is the next line in the Companies Act: a single director company must have a separate company secretary. You cannot be both. This guide explains the rule, who qualifies, what the secretary actually does, and the options if you do not have someone to hand.
The rule in the Companies Act 2014
The CRO summarises it clearly. Most company types must have at least two directors and a secretary. An LTD may have one director if it chooses, but where it has a single director, it must have a separate person registered as secretary. Section 134 of the Act prevents the sole director from also acting as secretary.
The reason is basic governance. Many documents must be signed by a director and the secretary, or by two directors. Dual capacity, where one person signs as both, is not allowed for a sole director. Having two named officers means there is always a second person accountable for the company's filings.
If the company has two or more directors, one of them can also be the secretary. The separate secretary rule only bites when there is exactly one director.
Who can be a company secretary?
The bar is low. The CRO states that the secretary of a private company is not required to have any formal qualifications. The requirements are:
- An individual secretary must be over 18.
- The secretary must not be an undischarged bankrupt.
- The secretary does not need to be resident in Ireland or the EEA. The residence rule applies to directors, not secretaries.
- Unlike a director, the secretary can be a body corporate, which is how corporate secretarial services operate.
The directors have a duty to make sure the person appointed has the skills or resources to carry out the role. For a small company that usually means someone organised enough to keep the registers and make sure the annual return goes in on time.
Common choices for a one director company
- A spouse, partner or family member.
- A business partner who is a shareholder but does not want to be a director.
- A corporate secretary service provided by a formation agent or firm.
- A second director, which removes the need for a separate secretary altogether.
What the company secretary does
The secretary's duties are mostly administrative, but they carry legal weight. In a small company they typically include:
- Annual return. Making sure Form B1 is filed with the CRO within 56 days of the annual return date, with financial statements attached where required. The first B1 is due six months after incorporation.
- Statutory registers. Keeping the register of members, register of directors and secretaries, minutes of meetings and other records listed in Section 216 of the Act at the registered office.
- Officer changes. Filing Form B10 within 14 days of any change of director or secretary, or change in their details.
- Registered office changes. Filing Form B2 when the address changes.
- Beneficial ownership. Filing with the RBO within five months of incorporation and updating within 14 days of any change.
- Signing. Co-signing the B1 and other documents alongside a director.
- Meetings. Recording resolutions and minutes of directors' and members' decisions.
The secretary is not responsible for running the business or for the accounts. That stays with the director. But because the secretary's signature is on the annual return, they share responsibility if it is late or wrong.
Using a corporate secretary service
If nobody suitable is available, a company can appoint a corporate secretary. This is a company that acts as secretary for a fee. Providers vary in what they include, from a name on the register only to a full service that prepares and files the B1, maintains the registers and issues reminders. Fees vary by provider; treat any figure you are quoted as approximate until you see the engagement terms.
A corporate secretary is appointed on the A1 at incorporation, or later by Form B10. The body corporate's name, registered office and company number go on the form.
What happens if you do not have a secretary
The CRO will not incorporate a single director LTD without a separate secretary named on the A1. The form is returned. After incorporation, if the secretary resigns and is not replaced, the company is in breach of the Act. Consequences include:
- The company cannot validly file its annual return, because the B1 needs a director and a secretary to sign.
- A late annual return costs 100 euro plus 3 euro per day, up to 1,200 euro, and can cost the company its audit exemption for two years.
- Failure to notify the CRO of officer changes within 14 days is a Category 3 offence.
- Persistent non-filing can lead to involuntary strike-off.
If your secretary leaves, appoint a replacement and file a B10 straight away.

Frequently asked questions
Can my spouse be the company secretary?
Yes, as long as they are over 18 and willing to take on the role. This is the most common arrangement in small Irish companies.
Can the secretary also be a shareholder?
Yes. Being a shareholder does not prevent someone from being secretary or director.
Do I need a secretary if I add a second director?
You still need a secretary, but one of the two directors can hold the role. The separate person rule applies only to single director companies.
Is the secretary personally liable for company debts?
No. Liability for debts sits with the company. The secretary can, however, be prosecuted along with the directors for filing offences such as a late annual return.
Does the secretary need to live in Ireland?
No. There is no residence requirement for the secretary.
