Key takeaways
- A sole proprietorship, or sole trader business, is one person trading in their own right, with no legal separation between owner and business.
- You register with Revenue as self-employed for free, and only register a business name if you trade under a name other than your own.
- Your profits are taxed as personal income, so you pay income tax, the Universal Social Charge and social insurance, and file a return each year.
- A limited company limits your personal liability and has a lower tax rate on trading profits, but it brings more filing and running costs.
What is a sole proprietorship?
A sole proprietorship is a business owned and run by one person, who trades in their own name without setting up a separate legal entity. In Ireland it’s usually called a sole trader business, and the two terms mean the same thing.
It’s the easiest way to start trading in Ireland, and Revenue’s overview of business types sets out how it compares. You make every decision and keep every euro of profit after tax, but you’re personally responsible for whatever the business owes.
Who a sole trader structure suits
A sole proprietorship suits people who want to start trading quickly, with light admin and full control. Freelancers, consultants, tradespeople and anyone running a side business alongside a job often start this way.
Picture a graphic designer landing their first few clients. They can register with Revenue, send invoices and start earning within weeks, without company paperwork. If the work grows or carries more risk, they can compare other business structures later.
Plenty of people in Ireland work for themselves. The Central Statistics Office (CSO) Labour Force Survey estimated 359,200 self-employed people in Q2 2026, up 0.8% on a year earlier.
Advantages of being a sole trader
The sole trader structure keeps costs and admin low, which helps when you’re starting out. Here’s what makes it appealing.
Easy and low-cost to set up
Registering with Revenue as a self-employed sole trader costs nothing. You can do it online or on paper with Form TR1, and there’s no company constitution or shareholder agreement to draft.
Simple tax reporting
Your business profits go on your personal tax return, a Form 11, rather than a separate company return. That keeps your accounting simpler and your compliance costs lower.
Full control over your business
Every decision is yours, with no directors or shareholders to consult. You can change your prices or services the day you decide to.
Keep all profits
Everything the business earns after expenses and tax belongs to you. There are no dividends to declare or profits to share, so the link between your effort and your income is direct.
Privacy of financial information
Limited companies file an annual return with financial statements at the Companies Registration Office (CRO) using Form B1. Sole traders have no equivalent filing, so your accounts stay private. If you register a business name, though, the name and your identity appear on the public CRO register.
Disadvantages of being a sole trader
The same simplicity that makes the structure easy to run also brings trade-offs. Weigh these before you commit.
Unlimited personal liability
There’s no legal line between you and your business. According to Citizens Information, if the business fails, your personal assets can be used to repay its debts. That could include your savings or your home.
Harder to raise capital and grow
You can’t sell shares to raise money, and lenders may see a one-person business as higher risk. Growth also depends on you, because the work and the admin both sit with one person.
Higher tax as your profits grow
Your profits are taxed as personal income, so profits above the standard rate band are taxed at the higher rate. You also pay the Universal Social Charge (USC) and Pay Related Social Insurance (PRSI). A limited company pays corporation tax on its trading profits instead, at a lower rate.
No business continuity
A sole trader business is tied to you personally. If you fall ill or retire, it doesn’t carry on as a separate entity, which can make it harder to sell or pass on.
Sole trader tax obligations in Ireland
As a sole trader, you’re taxed through self-assessment on your business profits. The figures below are for 2026 and reflect Budget 2026. Budget 2027 is due on 6 October 2026 and may change them, usually from January 2027.
Income tax and tax credits
According to KPMG’s Budget 2026 tables, income tax is 20% on the first €44,000 if you’re single, and 40% above that. For a married couple with one income, the 20% band is €53,000. So if you’re single with €50,000 profit, €44,000 is taxed at 20% and €6,000 at 40%.
Tax credits then reduce the tax you owe, starting with a €2,000 personal credit for a single person. You can also claim the Earned Income Tax Credit, worth the lower of €2,000 or 20% of your earned income. If you also have a job, this credit and your Employee Tax Credit together can’t exceed the maximum Employee Tax Credit.
Universal Social Charge
You also pay USC, unless your total income is €13,000 or less. The same KPMG tables set these 2026 USC rates:
- 0.5% on income up to €12,012
- 2% on income from €12,012.01 to €28,700
- 3% on income from €28,700.01 to €70,044
- 8% on income above €70,044
Self-employed income over €100,000 carries an extra 3%, so you pay 11% USC on that portion, as Citizens Information explains.
Class S PRSI
Self-employed people pay PRSI at Class S. The Class S rate is 4.2% until 30 September 2026 and 4.35% from 1 October 2026, with a minimum annual contribution of €650.
Class S builds your entitlement to benefits such as the State Pension (Contributory), Jobseeker’s Benefit for the Self-Employed, Maternity Benefit and Treatment Benefit. Illness Benefit isn’t included, which is why income protection insurance is worth a look.
VAT registration
You must register for Value-Added Tax (VAT) once your turnover reaches, or is likely to reach, a set threshold in any 12-month period. Revenue’s VAT thresholds are €42,500 if you supply services and €85,000 if you supply goods. If you sell both, the €85,000 threshold applies only when at least 90% of your turnover comes from goods.
Pay and file deadlines
Each year’s main deadline is 31 October, known as pay and file. By 31 October 2026, you file your 2025 Form 11, pay any balance of 2025 tax and pay preliminary tax for 2026.
If you both file and pay through the Revenue Online Service (ROS), Revenue extends the deadline to 18 November 2026. Filing online and paying another way keeps you on the 31 October date.
Business expenses and records
You can deduct expenses incurred wholly and exclusively for your business, a test set out in Revenue’s Tax and Duty Manual. If you use your car for work and personal trips, for example, you claim only the business share.
Equipment such as a laptop or van is claimed through capital allowances, at the standard wear-and-tear rate of 12.5% a year over eight years. You also need to keep your records, such as invoices and receipts, for six years.
How to set up as a sole trader in Ireland in 5 steps
Setting up takes a few registrations and some basic admin. Follow these five steps to start trading properly.
- Register with Revenue as self-employed through myAccount or ROS. Your Personal Public Service Number (PPSN) then becomes your tax reference number.
- Register any trading name other than your own with the CRO within one month. The registration fee is €20 online or €40 on paper.
- Register for VAT if your turnover is likely to reach the threshold for goods or services in any 12-month period.
- Open a separate business bank account and set up a system for tracking your expenses. Keeping the money apart makes your Form 11 easier.
- Check whether your trade needs a licence or permit, and arrange insurance before you take on your first job.

Sole trader vs limited company in Ireland
Choosing between a sole trader structure and a limited company is one of the biggest early decisions you’ll make. The biggest differences are how much personal risk you carry and how your profits are taxed.
Key differences
Each structure suits a different stage of business. Compared with a limited company, a sole trader business:
- is legally the same as you, while a company is a separate entity that limits your personal liability
- pays income tax, USC and PRSI on profits, while a company pays corporation tax at 12.5% on trading income and 25% on non-trading income
- keeps its accounts private, while a company files financial statements with the CRO each year
- lets you draw money as you need it, while a company pays you through salary or dividends
When a sole trader structure makes sense
A sole trader structure often fits when you’re starting out, your work is low-risk and your profits sit mostly within the standard rate band. It keeps costs down while you test your idea.
A company may suit you better once profits regularly reach the 40% band. It also helps if you want to protect personal assets or bring in investors. An accountant can model the tax difference and help you time the change.
Supports for sole traders in Ireland
State-backed supports are open to sole traders as well as companies. The two main starting points are your Local Enterprise Office and Microfinance Ireland.
There are 31 Local Enterprise Offices across Ireland, offering advice and mentoring to small businesses. They’re a first stop for local supports and can refer you to Microfinance Ireland for funding.
Microfinance Ireland offers unsecured business loans of €2,000–€25,000, so you don’t need to put up collateral. Sole traders qualify if the business has fewer than 10 staff and turnover under €2 million.
Legal considerations and insurance
Trading as a sole trader involves little paperwork, but you’re still responsible for meeting the rules that apply to your trade. That can include licences or permits and the health and safety rules for your type of work.
Insurance matters more for sole traders because of unlimited personal liability. Cover worth considering includes:
- public liability insurance, for claims when someone is injured or their property is damaged because of your work
- professional indemnity insurance, for claims that your advice or service caused a client financial loss
- income protection insurance, which replaces part of your income if illness or injury stops you working
- equipment cover, for your tools and stock against theft or damage
You can read about other cover options before speaking to a broker who works with small businesses.

FAQs on sole proprietorship
Here are answers to common questions about running a sole proprietorship in Ireland.
Is a sole proprietor the same as a sole trader?
Yes, they’re the same thing. Sole proprietor is more common in the US, while Irish bodies such as Revenue use sole trader or self-employed.
Can a sole trader have employees?
Yes, you register with Revenue as an employer and run Pay As You Earn (PAYE) on their wages. Since 1 January 2026, you must also enrol eligible staff in My Future Fund at a 1.5% employer contribution, which covers them but not you.
Can I switch from sole trader to a limited company later?
Yes, you can incorporate a company at any point and move your business into it. Plan for new filings, as a company’s first annual return date is six months after it’s incorporated.
Do I have to pay PRSI if I earn under €5,000?
No, self-employed income under €5,000 a year is exempt from PRSI. You can choose to pay €650 as a voluntary contributor to keep building your social insurance record.
Can I be employed and a sole trader at the same time?
Yes, your salary stays taxed under PAYE while you register as self-employed for the side business. You then file a Form 11 each year covering all your income, including your business profits.
