How to register as a sole trader in Ireland: the two steps

Do you have to register?

Two situations, and they work differently.

If self-employment is your main income.

Revenue's guidance is that you should register for Income Tax self-assessment if you are self-employed. There is no minimum income. That holds whether you clear €2,000 in your first year or €60,000.

If you have a Pay As You Earn (PAYE) job and work for yourself on the side.

Revenue treats you as a "chargeable person", meaning someone who has to register and file a Form 11 return, once your side income passes either of two figures:

• Net non-PAYE income of €5,000 or more. Net means what is left after allowable expenses, losses and capital allowances.

• Gross non-PAYE income of €30,000 or more. Gross means everything you invoiced, before any expenses come off.

You only have to pass one of them. Say you resell equipment: you invoice €34,000 over the year and spend €30,000 buying stock. Net income of €4,000 sits under the first threshold, but the €34,000 gross figure clears the second, so you are a chargeable person and you register.

Below both figures you may not need to register. Revenue asks you to declare that income on a Form 12 through myAccount instead, and codes it against your tax credits to collect what you owe. A salaried designer earning €3,000 from evening work usually sits here.

What to have ready

• A Personal Public Service (PPS) number. You cannot register with Revenue without one, so start there if you do not have it.

• A myAccount or Revenue Online Service (ROS) login.

• Your start date. The date you began trading, or intend to. It sets your first filing period.

• A description of what you do, and your business name if you plan to use one.

Step 1: Register for income tax with Revenue

Revenue charges nothing for this, and it is the step that makes you a sole trader. It moves you out of PAYE and into self-assessment, where you work out what you owe and pay it yourself.

If you are a PAYE employee, sign in to myAccount, go to Manage My Record, open tax registrations and register for Income Tax. Revenue sets out the process for registering as a sole trader on its own site. You can register while still employed, and plenty do.

If you already use ROS, add Income Tax through the eRegistration service instead.

If you cannot register online, use the paper Form TR1, which also covers Value-Added Tax (VAT). Non-residents registering for Irish tax for the first time use the TR1 (FT) version, and Revenue will not process a paper application from anyone who could have registered online.

Once it goes through, your Tax Reference Number is your PPS number and you get a Notice of Registration confirming it. Revenue also registers you for Class S Pay Related Social Insurance (PRSI) at the same time, which is what builds your State Pension entitlement.

Step 2: Register your business name, if you use one

Only if you trade under a name that is not your own. Aoife Byrne can work under her own name without registering anything else, but Byrne Ceramics goes on the register at the Companies Registration Office (CRO).

Register the name within one month of adopting it, not within a month of your first invoice. The month runs from the day you start using the name, so if you have been trading under a brand for a while, register now rather than waiting.

The CRO fee schedule sets two routes:

• Online through CORE, the CRO's filing system, using Form RBN1 for an individual. €20.

• On paper, using the Form RBN1. €40.

You will get a Certificate of Registration, which you have to display prominently at your place of business. You will generally need it to open a business bank account too.

Registration buys you less than you might assume. The CRO does not check your proposed name against the company, business name or trade mark registers, and registering it gives you no protection against someone else using it. So if you register Byrne Ceramics on Monday, nothing stops a Byrne Ceramics opening in the next county on Tuesday. Search those registers yourself before spending anything on signage.

Step 3: Check whether other taxes apply

Value-Added Tax. Revenue sets the VAT thresholds at €42,500 for services and €85,000 for goods, and registration becomes obligatory once your turnover passes, or looks likely to pass, the one that applies to you. The test runs on any rolling 12 months rather than your calendar year, which is where you can get caught out.

Employer PAYE and PRSI. Only if you take on staff. Being a sole trader does not stop you employing people.

Relevant Contracts Tax. Relevant Contracts Tax (RCT) applies if you subcontract in construction, forestry or meat processing.

If any of these apply from the start, Form TR1 registers you for several at once.

What you owe once you are registered

Pay and file by 31 October. Each year by that date you file your return for the previous year, pay any balance on it, and pay preliminary tax for the current one. Preliminary tax is an advance payment towards the year you are in, estimated from the income tax, PRSI and Universal Social Charge (USC) you expect to owe. Filing through ROS usually earns an extension into November, and Revenue confirms the date each year.

Class S PRSI. Contributions run at 4.2% of your income after allowable expenses, or €650, whichever is greater, and all PRSI rates rise by 0.15% on 1 October 2026. Earn under €5,000 from self-employment and you are exempt. Class S covers the State Pension (Contributory) and Maternity Benefit, but not short-term illness payments.

Records and expenses. Keep every invoice, receipt and bank statement. You can claim a deduction for costs incurred wholly and exclusively for the business, and for pension contributions.

What registering does not do

Registering settles your tax position and leaves your legal exposure where it was. You and the business are the same legal person, so if it fails, your creditors can pursue your personal assets, meaning anyone the business owes money to.

Ireland does not generally require sole traders to insure against that. Motor insurance is compulsory to drive in a public place, so if you drive for work, check your policy covers that use. Beyond that, Citizens Information notes that you are not legally obliged to be insured in business while advising cover for various situations, and gives the example that if the public has access to your premises you should have public liability insurance.

Clients apply the pressure long before the State does. Contracts, venues, landlords and site operators often want proof of cover at a stated limit, and they tend to ask after you have won the job.

What fits depends on the work. Public liability responds when your work injures someone or damages their property: a customer trips over the cable running to your till, or you put a drill through a client's water pipe. Professional indemnity responds when your advice or your service is alleged to have cost a client money, like a costing error in a quote they then build a budget around. Employers' liability is cover for claims brought by your own staff, so it matters once you hire.

Sorting that out before a contract requires it is easier than sorting it out afterwards.

The short version

1. Get a PPS number if you do not have one.

2. Register for income tax with Revenue through myAccount, ROS or Form TR1. No fee.

3. If you use a business name, register it with the CRO within one month. €20 online, €40 on paper.

4. Add VAT, employer or RCT registrations if they apply.

5. Diarise 31 October, keep proper records, and sort out cover before a client asks for it.
