Ireland's sole trader basics: VAT thresholds, self-assessment, and the pay-and-file deadline
Freelancing in Ireland as a sole trader means self-assessment with Revenue: income tax, USC and PRSI on your profits, VAT only once you pass the threshold, and one pay-and-file deadline each year that trips up first-timers.

Freelancing in Ireland is usually simplest as a sole trader: you register with Revenue (via ROS/eRegistration), and file under self-assessment. Three things are worth getting straight before your first invoice.
What you pay on your profits
A sole trader pays three charges on business profits: Income Tax (20% then 40% bands), the USC (Universal Social Charge), and PRSI Class S for the self-employed (with a minimum annual amount). You calculate them yourself on the annual Form 11 — the essence of self-assessment.
VAT: only once you cross the threshold
Unlike Spain, Ireland has a VAT threshold, and it was raised for 2025:
You must register for VAT once your turnover exceeds the threshold in any 12-month period; below it, registration is voluntary (sometimes worth it to reclaim input VAT). A separate €10,000 threshold covers cross-border distance sales and digital services.
The deadline that catches first-timers
Irish self-assessment hinges on one pay-and-file date a year.
By that date you do two things at once: file the previous year's return and pay preliminary tax for the current year. Preliminary tax is your estimate of this year's liability, and it must be at least the lower of 90% of the current year or 100% of the prior year. Underpay and you face interest and surcharges — which is why first-timers, who owe a full year's tax and a preliminary payment together, feel the squeeze. Setting money aside monthly is the boring fix.

Frequently asked questions
What are the VAT registration thresholds in Ireland?
Since 1 January 2025, €42,500 for a person supplying services and €85,000 for goods (a distance-selling/digital threshold of €10,000 also applies). You must register once turnover exceeds the threshold in any 12-month period; below it, registration is voluntary. The service and goods figures were raised from €40,000 and €80,000.
What is preliminary tax and the pay-and-file deadline?
Irish self-assessment runs on one annual pay-and-file date (31 October, with a ROS extension into mid-November). By then you file the previous year's Form 11 and pay preliminary tax for the current year — an estimate that must be at least the lower of 90% of the current year's liability or 100% of the prior year's. Missing it triggers interest and surcharges.
