When you’re working remotely in Ireland for a company back home or elsewhere, a big question quickly comes up: where do I pay tax?
You’d think it’s a simple either-or answer. But once you mix remote work with a foreign employer, it can become quite complex. Should you pay your tax to the Irish Revenue Commissioners in Ireland? Your employer’s local tax office? Or somehow both?
In this guide we will break down how tax residency impacts your tax liability when you are remote working and which country has taxing rights on your income. Plus, we’ll look at how tax treaties can protect your income and make sure you’re not taxed twice on the same earnings.
Understanding Tax Residency in Ireland
Before you can answer where you pay tax, you have to figure out where you’re a tax resident.
Tax residency here in Ireland is based on the number of days you spend in the country during a tax year.
Ireland considers you a tax resident if you spend:
- 183 days or more in the country in a single tax year, or
- 280 days or more over two consecutive years, with at least 30 days in the second year.
If you’re considered a tax resident in Ireland, you’re usually taxed on your worldwide income. And yes, that includes your salary from a foreign employer.
Even if you are not an Irish tax resident your Irish source income is taxable in Ireland. Generally speaking, income earned from work carried out in Ireland is considered Irish source.
Residency determines quite a lot, and once it’s cleared up you can then move into:
- Which country has primary taxing rights
- Determining where your income has been ‘sourced’
- How double tax treaties apply
- What happens if you’re tax resident in two countries
- Employer payroll and registration obligations
So start with residency.
Which Country Has the Right to Charge You Income Tax?
If you’re living in Ireland and physically carrying out your job here – even if your employer is based abroad – Ireland will usually have the primary right to tax your salary.
Why? Because employment income is generally taxed where the work is performed. If you’re sitting at your kitchen table in Dublin or Cork doing the job, that income is considered Irish-source income.
But that doesn’t always stop your home country from having an interest. Your original country may still try to tax that income if:
- You’re still considered tax resident there
- You haven’t formally broken your tax ties
- The country taxes based on citizenship rather than residency (for example, the US)
This is where things can overlap. Ireland may have the right to tax the income because the work is completed here, but your home country may also claim a right based on residency or citizenship.
That overlap is what creates the risk of double taxation – and why tax treaties become so important; meaning the value of professional advice cannot be understated.
A Word on Employer Obligations
This is the part that often surprises people. If you’re working remotely in Ireland on a permanent or long-term basis, your foreign employer is often required to register as an employer with Irish Revenue – even if they have no office here.
In many cases, this means setting up a payroll which allows Irish PAYE, PRSI, and USC to be deducted correctly. It’s not optional if Irish payroll obligations arise andd is something you should discuss with your HR department early.
Remember, remote work across borders creates employer compliance responsibilities not just personal tax questions!
How to Avoid Double Taxation as a Remote Working Expat in Ireland
If both Ireland and your home country believe they have the right to tax your income, it doesn’t automatically mean you’ll end up paying twice.
This is where Double Tax Agreements (DTAs) are incredibly helpful.
Ireland has tax treaties with many countries. These agreements are designed specifically to prevent double taxation. They work in a few ways:
- Tax credits: If you’ve already paid tax on your income in one country, the other country will usually give you a credit for that amount – so you’re not taxed on the same income twice.
- Exemptions: Sometimes a tax treaty makes it clear that only one country is allowed to tax that income. In that case, the other country steps back.
- Tie-breaker rules: If both countries see you as a tax resident, the treaty includes rules to decide which one gets priority, so you’re not stuck in the middle.
The thing to understand is that tax treaties don’t remove your obligation to report income. You still need to declare your earnings properly in the relevant country. The treaty simply makes sure you’re not taxed twice on the same income while attempting to meet your tax obligations in two locations.
To protect yourself during remote working arrangements in Ireland:
- Make sure your tax residency position is clear.
- Formally break tax residency in your home country if you’ve permanently moved.
- Check whether you need to file returns in both countries.
- Confirm whether foreign tax credits are being applied correctly.
Remote working across borders is common now, but the tax rules haven’t become any simpler. Getting clarity early can prevent costly mistakes later.
How to Claim Double Tax Relief In Ireland
A tax treaty gives you the right to relief – but you still have to claim it properly.
If you’re a tax resident in Ireland and you’ve already paid tax on the same employment income in another country, you’ll usually claim a foreign tax credit through your Irish tax return.
In practical terms, that means:
- You declare your full income in Ireland
- You confirm how much tax you’ve already paid abroad
- Revenue gives you credit for that foreign tax – up to the Irish tax due on that income
The goal is always to make sure the same income isn’t taxed twice.
For some remote workers, this means registering for Irish self-assessment – particularly if your salary isn’t being processed through an Irish payroll. That catches a lot of people off guard in their first year.
If both countries treat you as a tax resident, the relevant double tax agreement includes tie-breaker rules to decide which country takes priority. In more complex cases, you may need formal confirmation of your residency position before relief can be applied properly.
Don’t Overlook Remote Working Relief (2026)
One final point many expats miss. If you’re working remotely from home in Ireland and your employer isn’t paying you a tax-free daily allowance (up to €3.20 per day), you may be entitled to claim Remote Working Relief.
In 2026, you can still claim 30% of eligible electricity, heating, and broadband costs for the days worked from home. This relief is claimed through your annual tax return.
It won’t transform your tax bill – but it’s money you shouldn’t leave on the table.
