Key legislation
Partnership Act 1890 (adopted), Companies Act 2014
Ireland adopted the UK's Partnership Act 1890 and it remains in force. The Companies Act 2014 consolidated all prior company law into a single statute. Ireland's 12.5% corporate tax rate (15% for multinationals with revenue over €750M under OECD Pillar Two) and EU membership make it attractive for international startups. The Enterprise Ireland and SURE (Start-Up Refunds for Entrepreneurs) schemes provide additional startup support.
Default partnership rules in Ireland
Ireland's partnership law derives from the Partnership Act 1890, identical to the UK version. Partners share profits and losses equally by default. Every partner may take part in the management of the partnership. No person can be introduced as a partner without the consent of all existing partners. Any partner may dissolve the partnership by giving notice. The Act's provisions apply unless a written partnership agreement says otherwise. Irish partnerships are not separate legal entities from their partners.
The most important takeaway: profits are split equally by default in Ireland, regardless of capital contributions. If you and a partner start a business and one of you invests €100,000 while the other invests €5,000, you still split profits 50/50 without a written agreement. This default can be overridden by a partnership agreement.
Private Company Limited by Shares (LTD) in Ireland
The Private Company Limited by Shares (LTD) is the default entity for Irish startups under the Companies Act 2014. There is no minimum share capital requirement. Formation costs €50 for online filing through the CRO (Companies Registration Office) and takes 5–10 business days. The company must have at least one director who is EEA-resident (or obtain a Section 137 bond). A constitution replaces the old memorandum and articles of association. Without a shareholders' agreement, the company's constitution and the Companies Act 2014 govern shareholder relationships.
Without a shareholders' agreement, the relationship between founders is governed by the country's default rules, which rarely account for the realities of a startup — where contributions change over time and early effort often goes uncompensated. An operating agreement or shareholders' agreement is essential. Use our equity calculator to determine a fair split based on actual contributions.
What happens when a partner leaves in Ireland
Under the Partnership Act 1890, any partner can dissolve the partnership by notice. Upon dissolution, assets are applied to pay debts and liabilities, then to return capital contributions, then to distribute any surplus equally. For companies, directors can resign but shares are only transferred or bought back according to the constitution or a shareholders' agreement. The Companies Act 2014 provides remedies for oppressed minority shareholders under Section 212.
A written agreement should address departure terms specifically, including how the buyout value is calculated, the payment timeline, vesting schedules, and any non-compete provisions. Understanding the concept of dead equity is important for managing these situations. Learn more about how dead equity affects businesses.
Marriage and business equity in Ireland
Ireland does not have community property. The Family Law (Divorce) Act 1996 gives courts broad discretion to make "proper provision" for spouses on divorce. The court considers each spouse's income, earning capacity, property, financial needs, and contributions to the family. Business interests can be divided as part of the settlement. Pre-nuptial agreements are not currently given statutory recognition in Ireland, though they may be considered as one factor among many.
Ireland uses equitable distribution in divorce proceedings under the Family Law (Divorce) Act 1996. While Ireland's separate property regime is generally more favorable for business owners, a clear equity agreement and proper documentation of ownership remain important for protecting your interests.

Frequently asked questions
What is the default partnership split in Ireland?
Under the Partnership Act 1890, which Ireland adopted from the UK, profits and losses are shared equally among all partners by default. This applies regardless of capital contributions. A written partnership agreement can set a different arrangement.

Online filing through the CRO costs €50. There is no minimum share capital requirement. Formation typically takes 5–10 business days. At least one director must be EEA-resident or the company must obtain a Section 137 bond.
Is Ireland's 12.5% tax rate available to startups?
Yes. The 12.5% corporate tax rate applies to trading income for all Irish-resident companies. Startups may also qualify for the three-year corporate tax exemption for new companies earning less than €40,000 per year, with marginal relief up to €60,000.
Are pre-nuptial agreements enforceable in Ireland?
