The million-dollar question faced by Irish residents in a start-up scenario is, “Should I form a Limited Company or Sole Trader?”
The answer depends on several factors: the nature of your business, expected turnover, whether you’ll maintain other employment, the level of commercial risk, whether you intend to raise investment, and your long-term tax and pension goals.
While this guide gives you the essentials, the best advice is always to speak with an Accountant or Tax Advisor. A good advisor will assess your plans and explain the pros and cons of each structure. If you’d like us to connect you with a trusted accountant in your area, feel free to contact us — we work with professionals nationwide.
What is the Difference Between a Limited Company and a Sole Trader?
A Limited Company is a separate legal entity from its Directors and Shareholders. It must file Annual Returns with the Companies Registration Office (CRO) and follow statutory compliance requirements. Although there is more administration, a company can offer significant benefits in terms of tax efficiency, limited liability, and professional credibility.
A Sole Trader (or Partnership) is simpler and cheaper to set up. However, there is no legal separation between the individual and the business. You are personally liable for all debts. If you trade under any name other than your own, you must register a Business Name with the CRO (e.g., “John Smith Carpentry”).
Advantages of a Limited Company:
- Limited Liability – This means that the liability of the shareholders is limited to the amount paid for shares. This can only be changed if Directors have traded fraudulently or negligently, or if they continue to trade when the company has been struck off.
- Low Corporation Tax – The rate of corporate tax in Ireland is only 12.5%.
- Separate Legal Entity – The business is a separate legal entity from the people involved (Directors & shareholders)
- Name Protection – The company name is protected, meaning nobody else can use the name as a limited company name.
- Tax-Efficient Pension Options – Directors can make large, tax-efficient employer pension contributions.
- Professional Credibility – Business can appear more credible when bidding for tenders, signing contracts, etc.
- Clear Ownership Structure – Clear and defined ownership and duties. Useful for bringing in investors or issuing shares.
Disadvantages of a Limited Company:
- More Compliance – There is more compliance necessary with a limited company. Annual Returns with the CRO, tax filings, bookkeeping, and statutory obligations, etc.
- Higher Set-Up and Wind-Down Costs – There are higher costs to open the business, accountancy fees, and potential strike-off processes.
- PPSN Requirement – All Directors are required to provide a PPS number, or equivalent, to the CRO upon incorporation.
Advantages of Sole Trader/Partnership:
- Low Start-Up Costs – Simple and inexpensive to register.
- Low Running Costs – Fewer administrative obligations mean lower costs to run your business.
- No CRO Annual Returns – You do not need to file Annual Returns with the CRO unless a Business Name is registered (and even then, no financial statements are required).
Disadvantages of a Sole Trader/Partnership:
- No Limited Liability – No limit on personal liability for the debts of the business.
- Higher Personal Tax Rates – Profit is taxed at personal tax rates (up to 52%) instead of corporation tax at 12.5%.
- Limited Pension Planning Options – Compared with executive pensions in a company, sole traders/partnerships have limited scope to avail of pension tax breaks and executive pensions.
- May Appear Less Credible – May not be considered as credible as a limited company when tendering for contracts, etc.
