Sole Trader vs Limited Company in Ireland: Which Should You Choose?
There are two main ways to structure a business in Ireland: register as a sole trader or incorporate a limited company. A sole trader is legally the same entity as the person running it, with unlimited personal liability and income taxed at personal rates (20% up to €44,000, 40% above). A limited company is a separate legal entity, taxed at 12.5% corporation tax on trading profits, with the owner's liability generally limited to their shareholding. The right choice depends mainly on your profit level, appetite for risk, and how much admin you're willing to take on.
Liability: What Happens If the Business Can't Pay Its Debts
Sole trader: You and the business are the same legal person. If the business runs up debts it can't pay, creditors can pursue your personal assets, including your home, car, or savings. There's no legal wall between business and personal finances.
Limited company: The company is a distinct legal entity. Your personal liability is generally capped at the value of your shares (or any personal guarantee you've signed). If the company fails, your house and personal savings are normally protected, provided you haven't acted negligently or fraudulently as a director.
This is usually the single biggest factor for anyone in a higher-risk trade (construction, consultancy with large contracts, anything with material liability exposure).
Tax: Where the Real Difference Shows Up at Higher Profits
Sole trader tax:
- Profits are taxed as personal income through self-assessment, whether or not you draw the cash out of the business.
- Standard rate: 20% on income up to €44,000 (single person, 2026 rate).
- Higher rate: 40% above that threshold.
- USC also applies: 0.5% up to €12,012, 2% up to €28,700, 3% up to €70,044, and 8% above that. Self-employed income over €100,000 carries an additional 3% USC surcharge.
- PRSI (Class S for the self-employed) applies on top.
- Combined marginal rate at higher income levels can reach roughly 52–55%.
Limited company tax:
- The company pays corporation tax at 12.5% on trading income (25% on non-trading/investment income), not personal income tax rates.
- You only pay personal income tax, USC and PRSI on what you actually draw out as salary or dividends.
- Profits retained in the company (not drawn as salary or dividends) are taxed once, at 12.5%, rather than at your marginal personal rate — this is the core tax advantage as profits grow.
- Companies file an annual Corporation Tax Return (CT1) and pay tax within nine months of their accounting year end.
Where the crossover tends to happen: as a rough rule of thumb, once a business is consistently generating profit well beyond what the owner needs to draw as salary, the ability to retain profit at 12.5% rather than pay 40%+ personal tax on it starts to outweigh the extra compliance cost of running a company. There's no single "magic number" — it depends on your drawings, expenses, and pension planning — which is why this is worth a conversation with an accountant rather than a rule of thumb applied blindly.
VAT: The Threshold Is the Same Either Way
VAT registration rules don't differentiate between sole traders and limited companies — they're based on turnover, not structure. As of 2026, registration becomes mandatory once rolling 12-month turnover exceeds:
- €85,000 for the supply of goods
- €42,500 for the supply of services
Voluntary registration below these thresholds is allowed, and can make sense if you're B2B and want to reclaim input VAT on setup costs.
Setup and Ongoing Admin
Sole trader:
- Register for income tax with Revenue (via eRegistration or a TR1 form), linked to your PPS number.
- Minimal setup cost, no separate company filings.
- File one annual self-assessment tax return covering business and personal income.
Limited company:
- Register with the Companies Registration Office (CRO), including a company constitution and details of directors, secretary and shareholders.
- Requires a company secretary and at least one director.
- Annual obligations: CRO annual return, CT1 corporation tax return, statutory accounts, and minutes of directors'/shareholders' meetings.
- Materially higher accountancy and compliance costs than a sole trade.
Funding, Credibility and Continuity
A limited company can issue shares to raise equity finance, which a sole trader structure cannot do — sole traders are limited to personal savings, credit facilities, and loans. Companies also tend to carry more credibility with larger clients and suppliers, and they continue to exist independently of any one individual, so ownership can be transferred by selling shares rather than winding the business up. A sole trade is tied to the individual: if they stop trading, the business effectively ends with them.
The trade-off is privacy: company directors and shareholders are on the public record at the CRO, where a sole trader's affairs are not.
Quick Comparison

|---|---|---|
| Legal status | Same entity as the owner | Separate legal entity |
| Liability | Unlimited, personal assets at risk | Generally limited to shareholding |
| Tax on profit | Personal income tax (20%/40%) + USC + PRSI | 12.5% corporation tax (trading) |
| VAT threshold | €85,000 goods / €42,500 services | Same |
| Setup cost | Low | Higher |
| Ongoing admin | Annual self-assessment return | CRO returns, CT1, statutory accounts |
| Raising equity | Not possible | Can issue shares |
| Continuity | Tied to the individual | Continues independently |
Which One Is Right for You?
There's no universal answer, but as a starting point:
- Sole trader tends to suit: early-stage or side businesses, low-risk services, and anyone who wants to test an idea with minimal setup and admin before committing further.
- Limited company tends to suit: businesses with meaningful liability exposure, those retaining significant profit in the business rather than drawing it all out, and anyone planning to raise investment or bring in other shareholders.
Because the right answer depends on your specific profit level, risk exposure, and long-term plans, it's worth getting advice from a practising accountant before you register either structure — the cost of switching later (winding down a sole trade, or incorporating an existing one) is higher than getting it right at the outset.
