Setting up a company in Ireland and confused by share capital? You’re not alone. Most founders want to get the paperwork done and start trading, but the decisions you make about shares at incorporation can affect everything from investor readiness to control of your business down the line.

This guide breaks down what share capital actually means for limited companies in Ireland, explains the difference between authorised and issued share capital, and helps you choose the right structure for your new company.

What is share capital for an Irish limited company?

Share capital represents ownership in a company. When you set up a private company limited by shares (the most common company type in Ireland), the company issues shares to its shareholders. Each shareholder owns a proportion of the company based on the number of shares they hold.

Share capital matters at incorporation for three reasons:

Ownership and control. Shares determine who owns the company and, in most cases, who gets to vote on key decisions.
Investment readiness. A well-structured share capital makes it straightforward to bring in new investors or co-founders later.
Limited liability. A member of the company is only liable up to the nominal value of shares they hold. This is the core protection that limited companies offer.

Understanding share capital for limited companies doesn’t require a law degree. But getting it right at the start saves time, cost, and complexity later.

What is the difference between authorised share capital and issued share capital?

These two terms cause more confusion than almost anything else in company formation. Think of it this way: authorised share capital is the ceiling; issued share capital is what’s actually been allocated.

Authorised share capital is the maximum amount of share capital the company is permitted to issue under its constitution. It’s a limit, not an obligation. If your constitution says the company has an authorised capital of €100,000 divided into 100,000 shares at €1 each, that’s the most you can issue without amending the constitution.

Issued share capital is the number of shares actually issued to shareholders. These are the shares that people own right now, that carry voting rights, dividend entitlements, and capital rights if the company is wound up.

A new company might have an authorised share capital of €100,000 but only issue 100 shares at €1 each to its founders. The remaining 99,900 shares sit unissued, ready to be allocated when needed, without requiring a constitutional amendment.

Does an LTD need authorised share capital?

Here’s something many founders don’t realise: under the Companies Act 2014, a private company limited by shares (LTD) is not required to have an authorised share capital at all. This was a deliberate reform. An LTD can issue shares without a pre-set ceiling, provided the directors have authority to do so.

However, many companies still choose to include an authorised share capital in their company constitution because it provides a clear framework for future share issues and helps manage shareholder expectations regarding dilution.

What does nominal value mean, and do shareholders have to pay it?

Every share in an Irish limited company has a nominal (or par) value. This is an arbitrary monetary amount assigned to each share, such as €1, €0.01, or even €0.001. There is no statutory minimum par value under the Companies Act 2014.

The nominal value is not the same as the market value of the shares. A €1 share in a profitable company could be worth thousands. The nominal value simply represents the minimum price at which a share can be issued. Shares cannot be issued at a discount to their nominal value.

When shares are issued at incorporation, they’re typically fully paid. This means each shareholder pays the nominal value (e.g., €1 per share for 100 shares = €100). Any amount paid above the nominal value goes to the share premium account. For most new companies, shareholders pay the nominal value on incorporation and that’s the end of it.

What does issued share capital tell you about ownership?

Issued share capital is the practical side of company ownership. The shares in the company that have actually been allocated to shareholders determine:

Ownership percentages. If 100 shares are issued and you hold 60, you own 60% of the company.
Voting power. Unless different classes of shares apply, each share typically carries one vote.
Dividend entitlements. Profits distributed as dividends are split according to shareholding (for the same class of shares).

Common founder setups include:

Single founder: 100 ordinary shares issued to one person. Simple and clean.
Two founders (equal): 100 shares, 50 each. Or 1,000 shares, 500 each, for more flexibility.
Two founders (unequal): 100 shares split 60/40 or 70/30, reflecting different contributions or roles.

The number of shares you start with is less important than the ratio. Whether you issue 100 shares or 100,000, a 60/40 split is still a 60/40 split. What changes is how easily you can issue additional shares to investors later without dealing in fractions.

When would a company issue new shares?

Issued share capital isn’t fixed forever. A company can issue additional shares in several situations:

Bringing in a new co-founder or business partner
Raising seed funding or later investment rounds
Setting up employee share schemes
Converting loans or convertible notes into equity

Each time a company issues new shares, the existing shareholders’ percentage ownership is diluted (unless they participate in the new issue). This is why planning your share structure early matters, particularly if fundraising is on the horizon.

What share capital amounts are recommended for new limited companies in Ireland?

There’s no single right answer, but certain approaches are well established in practice:

Standard formation: 100 ordinary shares at €1 each (€100 issued share capital). This is the most common structure for new Irish limited companies and works well for businesses with no immediate plans to raise external investment.
Startup / investor-ready: 100,000 shares at €0.001 each, with a smaller number issued to founders initially. This structure makes it easier to issue shares to investors at a premium without awkward fractional calculations.
Family business: A smaller number of shares (e.g., 100 at €1) with clear ownership reflecting family involvement. Different classes may be created later if needed.

Factors to consider when choosing your amount of share capital:

How many founders or shareholders are involved at the start?
Is external investment likely within the next two to three years?
Will you need an employee equity plan in the future?
Do you want administrative simplicity now, or maximum flexibility?

If you’re a single-member company with no plans to raise funding, 100 shares at €1 is perfectly adequate. If you’re a startup anticipating investor involvement, speak to an accountant or company secretary before incorporating. The cost of restructuring later is significantly higher than getting it right from the start.

Can there be different classes of shares in an Irish limited company?

Yes. Private companies in Ireland can create different classes of shares, each with different rights attached. The most common share class is “ordinary shares,” but companies can also create preference shares, non-voting shares, and what are sometimes called alphabet shares (Class A, Class B, etc.).

Rights that can differ by class include:

Voting rights (some shares may carry no vote, or multiple votes)
Dividend rights (preferential dividends, or different rates)
Capital rights on winding up (priority return of capital)
Conversion or redemption features

When should you create different share classes?

Most new companies start with a single class of ordinary shares. Different classes typically become relevant when:

Investors require preference shares with priority dividend or liquidation rights
Founders want to retain control through shares with enhanced voting rights
Tax planning requires separate share classes (e.g., for family members or directors of the company)
Different shareholder groups need different economic rights

Creating a new share class requires amending the company constitution and filing the appropriate notices with the Companies Registration Office. Under Section 90 of the Companies Act 2014, if new shares have rights differing from those previously issued, the company must notify the Registrar within 30 days.

Can you change share capital after incorporation?

Absolutely. Share capital is not locked in at formation. Common changes include:

Issuing more shares. The directors can allot new shares provided they have authority (either from the constitution or by shareholder resolution). A Form B5 (Return of Allotments) must be filed with the CRO within 30 days. The filing fee is €15.
Increasing authorised share capital. If the company has an authorised share capital cap and needs to exceed it, an ordinary resolution and constitutional amendment are required.
Reducing share capital. Under Section 84 of the Companies Act 2014, a company may reduce its share capital through the Summary Approval Procedure or by special resolution confirmed by the court.
Subdividing or consolidating shares. Turning 100 shares of €1 into 1,000 shares of €0.10, or vice versa.

Each change comes with its own company registration requirements. Keep your statutory registers up to date and file notifications with the CRO within the required timeframes. Your company secretary or accountant should manage these filings as part of ongoing company law compliance.

How does share capital differ across Irish company types?

Not all company types handle share capital the same way:

LTD (Private Company Limited by Shares): No minimum share capital. Authorised share capital optional. The most flexible structure.
DAC (Designated Activity Company): Must state authorised share capital in its constitution. No statutory minimum.
PLC (Public Limited Company): Requires a minimum allotted share capital of €25,000. Cannot commence business until the CRO confirms this requirement is met.
CLG (Companies Limited by Guarantee): No share capital at all. Liability is limited to the members’ guarantee (typically €1).
Unlimited companies: Shareholders have unlimited liability. Share capital structure varies.

For the vast majority of new businesses in Ireland, an LTD is the right choice. It offers the simplest formation process, maximum flexibility regarding share capital, and full limited liability protection.

Frequently asked questions

Do I need a large authorised share capital to start a company in Ireland?

No. An LTD doesn’t even need an authorised share capital. Many companies start with 100 shares at €1 each and never need more. However, if you’re planning to raise investment, setting up a larger authorised and issued share capital structure from the start avoids the cost and paperwork of amending your constitution later.

Are changes to share capital always notified to the Companies Registration Office?

Yes. Allotments require a Form B5 within 30 days. Changes to share rights require notification under Section 90. Capital reductions, subdivisions, and consolidations all have their own filing requirements. Accurate registers and timely CRO filings are essential for company compliance.

Can I issue shares later to investors or employees?

Yes, provided the directors have authority to allot. Shares may be offered to existing members first under pre-emption rights (they have at least 14 days to accept). For employee equity schemes or investor rounds, get professional advice to ensure the structure is tax-efficient and legally sound.

Will authorised share capital affect my tax or company valuation?

No. Authorised share capital is a nominal figure in the company constitution. It does not represent company valuation, revenue, or assets. A company with €100,000 authorised share capital and €100 issued shares is not “worth” €100,000. Valuation depends on the business itself, not the amount of shares authorised.

What happens if I reach my authorised share capital limit?

If the company has an authorised share capital and wants to issue shares beyond it, the shareholders must pass a resolution to increase the authorised capital and amend the constitution. This is straightforward but involves paperwork and CRO filings, which is why many practitioners recommend setting a comfortably high ceiling at formation.
