Key takeaway
Understand Irish tax residency rules for remote workers employed by a foreign company, including the 183-day rule and double taxation treaties.
Working from your laptop in Dublin for a company headquartered in New York or London sounds simple, but Irish tax law has clear rules about when this triggers Irish tax obligations. Here's what remote workers need to understand.
When Do You Become an Irish Tax Resident?
You're Irish tax resident if you spend 183 days or more in Ireland in a single tax year (January–December), or 280+ days combined across the current and previous tax year (with a minimum of 30 days in each). Once resident, your worldwide income — including salary paid by a foreign employer into a foreign bank account — generally becomes taxable in Ireland.
Does It Matter Where Your Employer Is Based?
Not for determining your personal tax liability — what matters is where you are physically working from, not where your employer or their payroll is located. A remote worker living in Cork and working for a US company is generally taxable in Ireland on that income once Irish tax residency applies, regardless of the employer having zero Irish presence.
What Should Your Employer Do?
Technically, once you're working from Ireland, PAYE withholding obligations can apply to your foreign employer, even without an Irish office. Many employers handle this via an Employer of Record (EOR) service or 'shadow payroll' arrangement to correctly withhold Irish tax. If your employer isn't set up for this, you may need to register for Revenue's self-assessment system and pay tax directly yourself, including preliminary tax payments.
How Do Double Taxation Agreements Help?
Ireland has treaties with over 70 countries to prevent the same income being fully taxed twice. If both Ireland and your home country claim tax residency over you, the specific treaty (often based on OECD model rules around 'centre of vital interests' and days present) determines which country has primary taxing rights. Check the specific treaty text via Revenue.ie, as terms vary by country.
What About Social Insurance (PRSI)?
Separately from income tax, you may also need to consider PRSI (social insurance) obligations, and possibly a certificate of coverage from your home country's system if a bilateral social security agreement exists, to avoid double social insurance contributions.
What Records Should You Keep?
Track your exact days present in Ireland versus abroad using a simple spreadsheet or app, keep employment contracts and payslips, and retain any correspondence with Revenue. This documentation is essential if your residency status is ever queried or if you need to claim treaty relief.
Frequently Asked Questions
How many days can I work remotely in Ireland before paying Irish tax?
Irish tax residency is generally triggered at 183 days in a single tax year, or 280 days combined across two consecutive years (with at least 30 days in each) — beyond this, worldwide income typically becomes taxable in Ireland.
Do I need to pay Irish tax if my foreign employer doesn't have an Irish office?
Potentially yes — tax liability depends on where you physically work from, not where your employer is based. Once Irish tax resident, your foreign employment income can be taxable in Ireland regardless of employer location.
What is an Employer of Record and do I need one?
An Employer of Record is a service that legally employs you in Ireland on behalf of your actual employer, handling PAYE, PRSI and compliance. It's not mandatory but is a common solution when a foreign employer wants to legally employ someone in Ireland without setting up an Irish entity.
Can I be taxed twice on the same income in Ireland and my home country?
Ireland's double taxation agreements with over 70 countries are designed to prevent this, generally through tax credits or exemptions, but the exact mechanism depends on the specific treaty — professional advice is recommended for complex cases.
Do I need to register with Revenue if I work remotely from Ireland?
In most cases yes, especially if your employer isn't operating Irish payroll — you'll likely need to register for self-assessment and file an annual tax return covering your foreign employment income.
