Company Share Buybacks in Ireland: Purchasing a Company's Own Shares

A company share buyback in Ireland is a company purchasing its own shares from one or more of its members. Under the Companies Act 2014 a company may not simply buy its own shares whenever it likes: the Act sets a general prohibition and then lists the routes that are allowed, with purchase under section 105, funded from distributable profits (or fresh share proceeds), being the route this guide outlines. This guide walks through the outline of that route, what happens to the shares afterwards, the filing and tax questions to raise, and who in the business needs to be involved. It is a general overview, not legal or tax advice, and the paperwork usually lands with the company secretary (see our guide to company secretary duties in Ireland).

The starting point: a general prohibition

The Companies Act 2014 (section 102, as shown on the Irish Statute Book) says a company may acquire its own fully paid shares only in specified ways. Those include transfer or surrender for no consideration, cancellation following a capital reduction, a court order, redemption or purchase under section 105, redemption of certain preference shares, and mergers or divisions. Any other acquisition is prohibited.

The same section states that a prohibited acquisition is an offence for the company and any officer in default, and that the purported acquisition is void. That is why the order of steps matters. A buyback that skips the authority or funding rules is not just untidy; it risks falling outside the routes the Act permits, and section 102 says an acquisition in a way the Act does not allow is void.

Before relying on any section, check the current consolidated version of the Act.

What section 105 requires in outline

Section 105 permits a company to acquire its own shares by purchase or, for redeemable shares, by redemption or purchase. In outline, the section deals with three things: how the purchase is paid for, who must authorise it, and what members must be told.

Funding

The purchase must be paid for out of profits available for distribution or, where the shares are to be cancelled, out of the proceeds of a fresh issue of shares made for that purpose. There are further rules where the shares were originally issued at a premium. In practice, whether a company has enough distributable profits is a question for its accounts and its advisers, which is one reason directors should not treat a buyback as a quick administrative step.

Authority

The acquisition must be authorised by the company's constitution, by the rights attached to the shares, or by a special resolution. The section then adds safeguards for the special resolution route:

• The resolution fails if a holder of the affected shares votes them and the resolution would not have passed without those votes.
• It cannot be passed as a unanimous written resolution, and in a majority written resolution the signing member's own shares are disregarded when checking the majority.
• Any member with voting rights may demand a poll.
• The purchase contract, or a written memorandum of its terms, must be made available to members, and it must name the members whose shares are involved.

A later variation of a purchase contract needs its own prior special resolution, and a purchase under an option is allowed only if the option terms were authorised by special resolution. The section also sets time periods for making the contract available; check the section itself for the detail rather than relying on a summary.

Cancel the shares or hold them in treasury

Section 106 says shares a company acquires under section 105 are either cancelled or held as treasury shares. It also says cancelling shares does not reduce the company's authorised share capital, and it explains how amounts move to undenominated capital where the buyback is funded from distributable profits.

Section 109 deals with treasury shares. As shown on the Statute Book, it sets a cap on the nominal value of treasury shares held at any one time, says the company cannot exercise voting rights on them, and says no dividend is payable to the company on them. The company can later cancel them or re-issue them, and a re-allotment needs a price range fixed by special resolution that remains effective for a limited period. The cap and the period are stated in the section itself and are not repeated here because they depend on the current wording; check the section on the day.

Filings with the CRO

The Companies Registration Office (CRO) share capital page (last updated 17 November 2025) lists several share-related forms, including Form B7 for certain alterations to share capital and Form H5 for a company buying its own shares. The page describes Form H5 as the form for a company's purchase of its own shares and mentions a limit linked to non-redeemable share capital. This guide does not rely on that wording. Our suggestion: confirm directly with the CRO, or with your adviser, which form and which time limit apply to your buyback before you rely on either.

The CRO page also says share transfers should be noted on the company's annual return, so check whether your buyback needs to be reflected there; our guide to the CRO annual return B1 filing requirements explains that process.

Tax treatment: distribution or capital gain?

Tax is often the deciding factor, so it should be raised before the resolution is passed. Revenue's Tax and Duty Manual Part 06-09-01, "Acquisition by a company of its own shares" (last reviewed January 2026), explains that where a company pays more than the original issue price, the excess is generally treated as a distribution, an anti-avoidance rule. Capital gains treatment can apply instead where the conditions in the relevant part of the Taxes Consolidation Act 1997 are met.

The manual lists conditions that include the type of company (an unquoted trading company or the unquoted holding company of a trading group), a trade-benefit test, a test that the buyback is not part of a scheme to give the owner a share in profits without a dividend, residence of the vendor, a minimum ownership period, a reduction in the vendor's interest, and that the vendor is not connected with the company afterwards. The manual also says the company files a return (Form AOS1) with its corporation tax return for the period in which the payment is made, and that in exceptional cases Revenue may give an advance opinion on the trade-benefit test. The manual contains specific periods and percentages. They change, so read the manual on the day rather than a summary of it.

Revenue has a separate manual (Part 06-09-02, last reviewed May 2025) for quoted companies. It says advance clearance is not required and that the company self-assesses whether the relevant section applies. Revenue's Part 06-09-01 manual also says costs incurred by a company in buying back its own shares are not allowed as a deduction for tax purposes, subject to an exception for certain expenditure on shares given as consideration for goods or services or to an employee or director.

Who needs to be involved

A buyback touches several roles. Directors will want to be satisfied about the funding and the company's position, and our summary of directors' duties under the Companies Act 2014 is a useful reminder of the standards they work to. The company secretary typically prepares the resolution, circulates the contract or memorandum, updates the registers and handles filings.

A practical approach: before the board meets, assemble a short file containing the latest accounts showing distributable profits, a draft of the purchase contract, a note of who must abstain or whose shares are affected, a tax adviser's view on distribution or capital treatment, and a list of the CRO filings you expect to make. Reviewing it together catches most problems early. This is our own suggestion, not a statutory checklist, and finance and legal teams in Dublin and elsewhere will have their own variations.

Frequently asked questions

Can an Irish private company buy back its own shares?

The Companies Act 2014 allows a company to acquire its own shares by purchase or redemption under section 105, subject to the funding, authority and disclosure rules summarised above. Any acquisition outside the listed routes is prohibited.

Does a buyback need a special resolution?

The Act says the acquisition must be authorised by the company's constitution, by the rights attached to the shares, or by a special resolution. Where a special resolution is used, there are safeguards on voting and on written resolutions.

What happens to the shares after the company buys them?

Section 106 says they are either cancelled or held as treasury shares. Treasury shares carry no votes and no dividends for the company, and the Act sets conditions on holding and re-issuing them.

Is the price paid treated as a dividend for tax?

It can be. Revenue's manual says the excess over the original issue price is generally treated as a distribution unless the conditions for capital gains treatment are met. Which applies depends on the facts, so take tax advice before agreeing a price.

Where do I check the current rules?

Check the Companies Act 2014 on the Irish Statute Book, the CRO's share capital page and Revenue's Tax and Duty Manual Part 06-09-01 on the day you plan the transaction.

A buyback is a structured process rather than a single decision, so work through authority, funding, filings and tax in that order and keep a record of each step.
