How to Set Up as a Sole Trader in Ireland – A Complete Guide
Updated: Oct 5
Starting a business as a Sole Trader is one of the simplest ways to start your own business in Ireland. However, simply starting to provide services or sell products is not enough to ensure that your business is properly set up and managed. Tax registration, choosing the right business structure, Revenue obligations, record keeping and subsequent tax returns all require appropriate preparation.
In this guide, we explain what a Sole Trader is in Ireland, who this type of business structure may be suitable for, how registration works and what obligations arise once you start trading. We also explain how PK Accounting Advisory Limited can support you when starting and running your business.
What is a Sole Trader in Ireland?
A Sole Trader is an individual who runs a business on their own account. In this structure, the business owner makes decisions about the business, is responsible for running it and reports the income from the business through their own tax affairs.
Revenue identifies Sole Trader as one of the main ways of operating a business in Ireland, alongside partnerships and companies. A Sole Trader is not a separate legal person from the individual running the business – the business is directly connected to the person who operates it.
In practice, this means that a Sole Trader:
runs the business in their own name,
makes business decisions independently,
is responsible for records and tax returns,
reports business profits through their own tax system,
can employ staff if the relevant employer obligations are met.
This is often a suitable option for people starting service-based businesses, freelancers, specialists, contractors and entrepreneurs who want to start trading without setting up a Limited Company.
Who may benefit from operating as a Sole Trader?
A Sole Trader may be a suitable option for someone who wants to start a business independently and whose business model does not require a separate company structure from the outset.
For example, this may include:
freelancers,
consultants,
self-employed professionals,
people providing services to individuals or businesses,
contractors and subcontractors,
people starting a service-based business,
people developing a side business alongside employment.
This does not mean that Sole Trader is the right structure for every business. When choosing a business structure, it is worth considering factors such as the nature of the business, the level of risk, expected income, planned growth and whether a company structure may be needed in the future.
It is therefore worth considering not only how easily you can start the business, but also which structure is appropriate for your particular situation.
Sole Trader vs Limited Company – what is the difference?
One of the key decisions when starting a business in Ireland is choosing between operating as a Sole Trader and setting up a Limited Company.
With a Sole Trader, the business is not a separate legal person from the individual, and business income is reported through the individual’s personal tax affairs.
A Limited Company, on the other hand, is a separate legal person. The company has its own structure, its own statutory and tax obligations and separate financial and tax reporting.
There is therefore no single answer to which structure is “better”. The choice should depend on the individual circumstances of the business owner and how they plan to operate the business.
If you are just starting out and are unsure whether Sole Trader is the right structure for your business, it is worth discussing this decision before beginning the registration process.
How to set up as a Sole Trader in Ireland
The process can be divided into several key steps.
1. Define your business activity
Before registering, you need to determine what your business will do.
The tax registration process requires information about the type of business activity, including the appropriate NACE code, the business start date and expected turnover. Revenue identifies these as part of the Income Tax registration process for someone starting a business.
It is therefore worth preparing a short and clear description of your business activity in advance and considering which services or products you will offer.
2. Make sure you have a PPSN
Before registering for tax as a Sole Trader, you need a Personal Public Service Number (PPSN).
Revenue states that a Sole Trader’s Tax Reference Number is linked to their PPSN. The PPSN becomes the tax reference used for business matters only after tax registration has been completed.
3. Register your business with Revenue
A Sole Trader must register for the relevant taxes.
Tax registration can be completed online through eRegistration. A person running a business can use the Revenue Online Service (ROS) and, in certain circumstances, myAccount.
During registration, you will need to provide information including details of the business activity, the start date and expected turnover.
Once registration has been completed correctly, you can begin trading under the appropriate tax system.
4. Do you need to register a business name?
Not always.
If a Sole Trader operates under their own name, they do not need to register a separate business name simply because they are self-employed.
However, if you want to operate under a name other than your own name, you may need to register a Business Name with the Companies Registration Office (CRO).
Revenue states that a Sole Trader can register a business name with the CRO using Form RBN1.
The CRO also points out that registering a Business Name does not provide legal protection for the name itself and does not automatically mean that the name is available or suitable from the perspective of other rights, such as trademark rights.
It is therefore worth checking the availability of the name before choosing it and making sure that it does not create legal or reputational issues.
5. Check whether you need to register for VAT
Not every Sole Trader needs to register for VAT immediately.
The requirement to register depends, among other things, on the type of business activity and turnover. For businesses supplying services only, the current mandatory VAT registration threshold is €42,500. Different thresholds apply to certain activities involving the supply of goods.
Voluntary VAT registration may also be possible where the relevant conditions are met.
It is important to remember, however, that VAT is not only a question of reaching a particular turnover level. The type of services provided, where services are supplied and international transactions may also be relevant.
If your business serves customers in other countries or involves cross-border sales, it is worth reviewing your VAT position before starting the business.
What taxes does a Sole Trader pay?
Income from a Sole Trader business is reported under the self-assessment system.
Depending on the circumstances, the business owner may be required to pay:
Income Tax,
PRSI,
USC,
and, in certain circumstances, VAT or other taxes relating to the nature of the business.
Revenue states that Sole Traders pay Income Tax, PRSI and USC on business profits.
For self-employed individuals, PRSI is generally dealt with under Class S. Current rules provide for a minimum annual contribution and a specific rate depending on income; the Class S rate changes from 1 October 2026.
For this reason, it is important not to look only at the amount of invoices issued to customers. For tax purposes, the key figure is the properly calculated income or profit that is subject to tax.
Revenue is not the same as profit
This is one of the most important things a new business owner should understand.
If a Sole Trader issues invoices totalling €50,000 during the year, this does not automatically mean that €50,000 is their taxable profit.
The tax calculation needs to take into account appropriate business expenses.
Revenue requires records to be maintained so that the correct business result can be established.
Not every private or mixed-use expense is a deductible business expense. The rules on deductibility depend on the nature of the expense and its connection with the business.
It is therefore worth separating business expenses from personal expenses from the beginning and keeping documentation supporting the costs incurred.
What records should a Sole Trader keep?
Running a business involves more than issuing invoices.
Revenue requires appropriate records to be maintained so that tax returns can be prepared correctly. Records may include:
sales invoices,
purchase invoices and receipts,
expense records,
bank statements,
accounting books and reports,
transaction records,
information required to prepare tax returns.
Revenue states that original required records should be retained for six years. Ultimate responsibility for maintaining proper records remains with the business owner, even if the records are handled by an accountant or tax agent.
Good organisation of records from the first day of trading can make future tax returns considerably easier.
Form 11 and the annual Sole Trader tax return
A Sole Trader is subject to the self-assessment system.
Annual income from the business is reported through Form 11, submitted through the Revenue Online Service (ROS).
The Pay and File system means that the business owner must report the previous tax year and pay the tax due, while also taking into account preliminary tax for the current year.
The standard deadline is 31 October. Where the required return and payment are completed through ROS, Revenue provides an extended deadline. For the 2025 tax return and preliminary tax for 2026, the ROS deadline in 2026 is 18 November.
Deadlines can change, so current Revenue information should be checked before each tax return.
What is preliminary tax?
For someone starting a business, it is particularly important to understand the concept of preliminary tax.
This is an estimated amount of Income Tax, PRSI and USC relating to the current tax year, which needs to be taken into account under the Pay and File system. Revenue states that preliminary tax is generally payable by 31 October of the relevant year.
The first year of trading may work slightly differently. Revenue provides specific rules concerning the first preliminary tax payment, so it is worth planning for these tax liabilities from the beginning of the business.
This is also important from a cash-flow perspective.
Tax should not come as a surprise at the end of the year. It is a good idea to set aside an appropriate amount of money for future tax liabilities from the beginning.
Can a Sole Trader employ staff?
Yes.
Operating as a Sole Trader does not mean that the business owner has to work entirely alone. A Sole Trader can employ staff, but additional employer obligations will then apply.
Revenue states that an employer must take account of obligations relating to Employer PAYE/PRSI and other employment requirements.
If you are planning to hire your first employee, it is therefore worth treating this as a separate stage of the business and preparing appropriately for payroll obligations.
Can you be a Sole Trader while also working under PAYE?
Yes, it is possible to operate as a Sole Trader while also being employed.
In this situation, your tax position becomes more complex because income from employment and business income need to be properly taken into account in your tax affairs.
Revenue allows a person who was previously registered as a PAYE employee to register for Income Tax self-assessment.
Therefore, if you are employed and also planning to start your own business, you do not automatically have to leave your employment. However, both sources of income need to be correctly set up and reported.
What else should you consider before starting your business?
Tax registration is only one part of starting a business.
Before starting, it is also worth considering:
Business bank account
Keeping business finances separate from personal finances can make it much easier to monitor income and expenses, even where the nature of the business does not require a separate business bank account.
Invoicing
It is worth deciding from the beginning how invoices and sales documents will be issued and stored.
Insurance
Depending on the type of business, appropriate insurance may be relevant, such as professional indemnity or business insurance.
Client agreements
For ongoing work with clients, it is worth clearly defining the scope of services, fees, payment terms and other conditions of the relationship.
VAT
If your business may approach the VAT threshold or involves overseas customers, it is worth reviewing the situation early rather than waiting until a particular turnover level has been exceeded.
Accounting
The most important thing is to establish how income, expenses and supporting documents will be recorded on an ongoing basis before the number of transactions starts to increase.
Is it worth using an accountant when setting up as a Sole Trader?
A Sole Trader can register independently. There is no requirement to use an accountant simply because you are starting a business.
Professional support can, however, be particularly valuable if:
you have no experience with the Irish tax system,
you are unsure which business structure to choose,
you are also working under PAYE,
you are planning to register for VAT,
you will have international customers,
you expect to employ staff,
you want to organise your records correctly from the beginning,
you do not want to handle your annual tax returns yourself.
In these situations, an accountant should not be seen only as someone who “does the tax once a year”. Well-organised support can also help you establish the right way of running and managing your business from the outset.
