How to register with Revenue for the first time?
Register through Revenue’s eRegistration service
- Log into your myAccount or ROS portal at ros.ie (Revenue’s online system) and navigate to ‘Manage My Record’ > ‘Tax Registrations’.
- Select ‘Income Tax’ and click ‘Register’ (Revenue).
- You’ll be prompted to confirm a NACE code — this classifies your business activity (Revenue).
- Submit the application.
- After submission, Revenue typically processes the application within 5–10 working days (Revenue).
eRegistration is the fastest route: no paper, no postage, and you get a confirmation letter within two weeks. For first-time sole traders, this digital flow is the recommended path.
Complete Form TR1 (Part A and Part B) if offline
- If you cannot use the online service, download Form TR1 from Revenue’s website and submit it by post (Revenue). Part A covers personal details, Part B covers business information.
- Processing time for paper applications may take longer than the online route — Revenue does not guarantee a specific turnaround (Revenue).
The trade-off: Paper is slower and carries no certainty on timing. If you’re starting a business within the next month and need your Tax Reference Number quickly, choose eRegistration.
How much does it cost to register as a sole trader in Ireland?
No registration fee for self-assessment or sole trader status
- Revenue does not charge any fee for registering as a sole trader or for self-assessment (Revenue). The entire registration process — whether online or paper — is free.
- VAT registration is separate and becomes mandatory only if your turnover exceeds €37,500 (services) or €75,000 (goods) (Kinore (Irish accounting platform)).
“Free registration” does not mean free taxes — once you’re registered, you’re liable for Income Tax, PRSI, and USC on your profits. The €0 sign-up cost is just the entry ticket.
The pattern: Ireland’s tax authority makes registration costless to remove barriers for new self-employed people. The real costs come later, in the form of tax payments and professional accounting fees.
How long does it take to register as self-employed in Ireland?
Processing time for eRegistration
- Online applications submitted through myAccount or ROS are typically processed within 5–10 working days (Revenue).
- After processing, you receive a letter or notification confirming your Registration Number and activating your myAccount (YouTube (government-affiliated walkthrough)).
Processing time for paper application (Form TR1)
- Revenue does not publish a standard turnaround for paper Form TR1 submissions. Estimates from third-party advisers suggest it can take 2–4 weeks (TaxReturned.ie).
- Because of postal handling and manual data entry, paper registration is inherently slower and less predictable.
Why this matters: If your business needs a Tax Reference Number to invoice clients or open a business bank account, the online route gets you operational faster. Paper is a fallback for those without internet access or with specific circumstances.
How do I register for my account with Revenue?
Create a myAccount on revenue.ie
- Visit ros.ie/myaccount-web/register.html and complete the three-step registration: fill in the form, enter the temporary password sent to you, then create your own password (Revenue myAccount).
- myAccount is the primary portal for individual taxpayers to file returns, view balances, and manage registrations.
Use the eRegistration service to obtain a Registration Number
- Once inside myAccount, select ‘Manage My Record’ → ‘Tax Registrations’ → ‘Income Tax’ → ‘Register’ (Revenue).
- After approval, you’ll receive a unique Revenue Registration Number — this is your official tax identifier for self-assessment.
The implication: Your myAccount and Registration Number are the keys to Ireland’s self-assessment system. Without them, you cannot file returns or make tax payments.
What is the 24 month rule for self-employed?
Travel and subsistence rules for temporary workplaces
- The 24-month rule limits tax-free travel and subsistence expenses for self-employed individuals working at a temporary location. After 24 consecutive months at the same site, expenses become taxable as a benefit-in-kind (Revenue self-assessment guide).
Qualifying conditions for the 24-month rule
- To claim tax-free travel expenses, the workplace must be temporary — meaning the assignment is expected to last 24 months or less. If the contract extends beyond that, the location becomes your permanent place of work and travel costs are no longer deductible.
What this means: Self-employed contractors in construction, consulting, or IT who move between client sites need to track durations carefully. After two years at one client, your tax bill may suddenly rise if you’ve been claiming mileage.
How much can a sole trader earn before paying tax in Ireland?
Income thresholds and tax bands for sole traders (2025)
- There is no tax-free allowance for self-employed income in Ireland — all profits above €0 are taxable (Revenue).
- Profits are taxed at the standard income tax rates: 20% on the first €42,000 (single, 2025) and 40% on the remainder, plus PRSI (4%) and USC (rates from 0.5% to 8%).
PRSI and USC obligations
- Self-employed individuals pay Class S PRSI at 4% on all profits above €5,000 (Revenue).
- USC applies on total income: 0.5% up to €12,012, 2% up to €25,760, 4.5% up to €70,044, and 8% above that.
The catch: Unlike employees who have a tax-free Personal Tax Credit (€1,875 in 2025), sole traders start paying tax from the first euro of profit. Proper bookkeeping is essential to avoid underpayment.
Timeline for self-assessment registration in Ireland
- Day 1 — Start self-employment or earn first income.
- Within 30 days — Register with Revenue via eRegistration or Form TR1 (Revenue).
- 5–10 working days after registration — Receive Registration Number and activate myAccount.
- 31 October following tax year — File annual Self-Assessment return if using paper (Kinore).
- Mid-November following tax year — File online via ROS (extended deadline for online filers) (Revenue).
The pattern: Missing the 30-day registration window can lead to penalties and interest. Mark your calendar as soon as you take on your first client.

Expert perspectives on registering as self-employed

For first-time sole traders in Ireland, the choice is straightforward: use the online eRegistration service to get your Tax Reference Number within two weeks, or risk delays with paper forms. The cost is zero, the deadline is firm at 30 days, and the consequence of missing it is a potential penalty. For anyone earning outside the PAYE system, registration isn’t optional — it’s the legal foundation of your self-employment.

Frequently asked questions
What documents do I need to register as self-employed?
You need your Personal Public Service (PPS) Number, your contact details, and a description of your business activity to select the appropriate NACE code. No other documents are required for basic registration (Revenue).
Can I register for self-assessment if I am employed and self-employed?
Yes. You can have both PAYE employment and self-employment income. Revenue’s myAccount allows you to manage both. You must register for self-assessment if your self-employment income is taxable (Revenue self-assessment guide).
Do I need a VAT number to register as a sole trader?
No. VAT registration is separate and only required if your turnover exceeds the thresholds (€37,500 for services, €75,000 for goods) (Kinore). Many sole traders never need a VAT number.
What happens if I do not register for self-assessment in Ireland?
Revenue can impose penalties for late registration, and you may miss the legal deadline to file returns. Failure to register could also result in Revenue issuing a default assessment, which may be higher than your actual tax liability (Revenue).
Can I register for self-assessment after the 30-day deadline?
Yes, but you should do it as soon as possible. There is no formal cut-off beyond the 30-day window — the deadline is a compliance requirement. Late registration may incur penalties, but Revenue will still process your application (Revenue).
How do I update my self-assessment registration details?
Log into myAccount or ROS and navigate to ‘Manage My Record’ to update your address, phone number, or business activity. For major changes like switching from sole trader to company, you may need to submit a new registration (Revenue).
Is it mandatory to register online or can I post Form TR1?
Both methods are accepted. Revenue’s official guidance directs most users to eRegistration, but Form TR1 remains available for those who cannot use the online service (Revenue).
