The question every new business owner asks
If you are starting a business in Ireland, one of the first decisions you will face is whether to operate as a sole trader or to incorporate as a limited company. It is a question I get asked almost every week at our Dundalk office, and there is no one-size-fits-all answer. The right structure depends on your income level, your appetite for paperwork, and how much personal risk you are comfortable carrying.
Let me walk you through the key differences so you can make an informed decision before you register with Revenue or the CRO.
What is a sole trader?
A sole trader is the simplest business structure in Ireland. You and the business are legally the same entity. You register with Revenue as a self-employed individual, file an annual Form 11 income tax return, and pay income tax, PRSI, and USC on your profits.
There is no requirement to register with the Companies Registration Office (CRO) unless you trade under a business name different from your own. Setting up is straightforward: you complete a TR1 form with Revenue, and you are in business.
The advantages are clear. Minimal paperwork, low setup costs, and complete control. You keep all the profits after tax, and your financial affairs remain private. There are no annual returns to file with the CRO, no company secretarial obligations, and no requirement to publish your accounts.
What is a limited company?
A limited company is a separate legal entity from its owner. You incorporate through the CRO, typically as a private company limited by shares (LTD). The company has its own tax reference number, files its own corporation tax return (Form CT1), and must submit an annual return to the CRO along with financial statements.
The key word here is “limited.” Your personal liability is limited to the amount you have invested in the company. If the business fails, your personal assets — your home, your car, your savings — are generally protected. That separation of personal and business liability is the single biggest reason people incorporate.
Tax: where the real difference lies
As a sole trader, your profits are taxed at your marginal income tax rate. In 2026, that means 20% on the first EUR 44,000 (for a single person) and 40% on everything above that. On top of income tax, you pay USC (up to 8%) and PRSI at 4%. At higher income levels, the effective tax rate for a sole trader can exceed 50%.
A limited company pays corporation tax at 12.5% on trading profits. That is a significant difference. However, you still need to extract money from the company to live on, and that extraction — whether as salary, dividends, or a combination — is itself subject to income tax, USC, and PRSI.
The real tax planning opportunity with a limited company comes from the ability to control the timing and method of extracting profits. You can leave retained earnings in the company, invest in the business, or make pension contributions through the company. A sole trader has less flexibility.
As a general rule of thumb, if your annual profits consistently exceed EUR 80,000 to EUR 100,000, a limited company structure will almost certainly save you tax. Below EUR 40,000, the administrative costs of running a company often outweigh the tax savings. In between, it depends on your circumstances.
Liability and risk
For sole traders, personal liability is unlimited. If your business is sued or runs up debts it cannot pay, your personal assets are on the line. For many service businesses with low risk profiles — a freelance graphic designer, for example — this may not be a major concern.
But if you are in construction, if you employ staff, or if your business carries any meaningful risk of a claim, limited liability is worth serious consideration. I have seen sole traders in Dundalk lose personal savings over a business dispute that would have been contained within a limited company structure.
Administrative burden
This is where sole traders have the clear advantage. A sole trader files one tax return per year (Form 11) and keeps basic records of income and expenses. That is it.
A limited company must file an annual return with the CRO (currently EUR 20 online), prepare and file financial statements that comply with company law — we detail every requirement in our guide to CRO filing requirements for Irish company directors — file a corporation tax return, operate PAYE/PRSI if directors take a salary, and maintain statutory registers and minutes. The annual compliance cost for a small limited company, including accountancy fees, CRO filing, and registered office, typically runs between EUR 2,500 and EUR 4,000.
Which is right for you?
There is no universal answer. Consider a sole trader structure if you are just starting out and your profits are modest, if you want to keep things simple, or if you are testing a business idea before committing fully.
Consider a limited company if your profits consistently exceed EUR 80,000, if you want to protect personal assets, if you plan to take on employees or significant contracts, or if you want to build a business you might sell in the future. Before you incorporate, it is worth understanding the legal duties that come with being a company director.
Talk to us before you decide
This is genuinely one of the most important decisions you will make for your business, and it is worth getting right from the start. Restructuring later — converting from sole trader to limited company or the reverse — is possible but involves costs, tax implications, and paperwork that could have been avoided.
