Quick Answer
What is the 75 percent rule for Irish tax credits? If you are an EU citizen living abroad but earning money in Ireland, you are not automatically entitled to full Irish tax credits. To get your full tax credits, at least 75 percent of your total worldwide income for the year must be taxable in Ireland. If your Irish income makes up less than 75 percent of your global earnings, your Irish tax credits will be reduced proportionally.

What is the 75 Percent Rule?
When you are a non-resident working in Ireland, the biggest factor in getting a tax rebate is how many tax credits you are allowed to use to lower your tax bill. That is why this page sits so closely beside our guide to tax rebates for non-residents working in Ireland.
Revenue's 75 percent rule is a specific test designed for EU citizens and nationals. It states that you can only claim your full, unreduced Irish tax credits if at least three-quarters (75 percent) of your entire worldwide income is subject to Irish tax.
This means that if you move to Spain but continue to work remotely for a Dublin company, or if you commute to Ireland for a few months of the year, Revenue will look at your total global earnings before deciding what tax credits you deserve.
Why Your Worldwide Income Matters
Many people assume that because they are only paying Irish tax on their Irish income, Revenue shouldn't care about what they earn in Germany, France, or Australia.
However, under the 75 percent rule, your foreign income is the deciding factor. The more money you earn outside of Ireland, the smaller your percentage of Irish income becomes. If that percentage drops below 75, your tax credits drop with it.

How Proportional Tax Credits Work
If you fail the 75 percent test, you don't lose your credits completely. Instead, you move onto proportional credits.
Revenue will calculate exactly what percentage of your global income came from Ireland, and they will give you that exact percentage of your tax credits. For example, if your Irish salary makes up 40 percent of your total worldwide income for the year, you will receive exactly 40 percent of your normal Irish tax credits.
This is why understanding your exact income breakdown is crucial before filing a claim. If you just emigrated, this rule heavily impacts your departure year, which we cover in detail in our complete guide to claiming tax back after leaving Ireland.
What MyTaxRebate Checks Before Submitting
We never submit a non-resident tax claim without doing the math first.
MyTaxRebate reviews your Irish earnings, your foreign earnings, your exact timeline, and your EU nationality status. We calculate your exact percentage to see if you cross the 75 percent threshold. If you don't, we calculate your proportional credits to ensure we are claiming the absolute maximum legal amount allowed by Revenue, without risking an audit.
Unsure What Your Global Income Ratio Is?
If you worked in Ireland but earned money elsewhere, you might still be owed a healthy refund. Let our team do the math to see exactly how many tax credits you can claim.
Tax Scenarios
Passing the 75 percent threshold
You are a French citizen who earns €40,000 in Ireland and €5,000 from a small business in France. Your total worldwide income is €45,000. Because your Irish income (€40,000) makes up 88 percent of your worldwide income, you comfortably pass the 75 percent test. You are entitled to 100 percent of your Irish tax credits.
Failing the threshold and getting proportional credits
You are a Spanish citizen who works in Ireland for a few months, earning €15,000. You then return to Spain and earn €35,000. Your total worldwide income is €50,000. Your Irish income is only 30 percent of your global total. Therefore, you fail the 75 percent test and will only receive 30 percent of your normal Irish tax credits.
A non-EU citizen scenario
You are a citizen of a non-treaty country outside the EU. You earn €30,000 in Ireland and have no other global income. Even though 100 percent of your income is Irish, the 75 percent rule is specifically an EU-focused relief. As a non-treaty, non-EU citizen, you are generally entitled to zero Irish tax credits, meaning your tax liability will be significantly higher.
Common Mistakes To Avoid
- ✗Assuming EU citizenship guarantees full credits: Your passport gets you in the door, but your income percentage decides the final amount.
- ✗Forgetting to declare foreign income: Hiding your overseas salary to try and pass the 75 percent test is tax evasion and will trigger a Revenue audit.
- ✗Confusing this with split-year treatment: The 75 percent rule is about tax credits. Split-year treatment is about shielding foreign income from Irish tax. They are two completely different rules.
When This Approach Does Not Apply
Key Takeaways

Frequently Asked Questions
What happens if exactly 75 percent of my income is Irish?
You pass! The rule states that your Irish income must be at least 75 percent of your worldwide income. Hitting exactly 75 percent entitles you to full Irish tax credits.
Do I have to pay Irish tax on my foreign income under this rule?
No. Revenue asks for your worldwide income purely to calculate your ratio and figure out your tax credits. They do not use this rule to suddenly tax your foreign salary.
Does this rule apply to UK citizens after Brexit?
Currently, UK citizens are generally still treated favorably under specific double taxation agreements, but the strict EU 75 percent rule technically applies to EU/EEA nationals. UK citizens usually rely on the Ireland-UK tax treaty for credit preservation.
How does MyTaxRebate prove my worldwide income to Revenue?
We work with you to gather your foreign payslips, foreign tax returns, or statements of earnings from your home country. We compile these into a compliant package that Revenue will accept.
