Irish tax for Australians: why your first Dublin pay packet looks so small

Your first Irish payslip isn't a mistake, it's emergency tax. Register your job on Revenue myAccount before payday and most of it never happens.

The short version

• If your employer can't get a Revenue Payroll Notification for you, you pay emergency tax: from week 5 every euro is taxed at 40%, plus a flat 8% USC [1][2].
• Fix it with three things: a PPS number, a Revenue myAccount, and your job added under "PAYE Services" [2].
• In 2026 a single employee gets €4,000 in tax credits, pays 20% on the first €44,000 and 40% above that, plus USC and PRSI [3][4][5].
• Overpaid tax usually comes back through payroll. Anything else you can claim for the last four years only [2][6].
• Ireland and Australia have had a tax treaty since 1983 and a social security agreement since 2006. Your ATO residency still needs sorting separately [8][9][10].

How Irish tax differs from home

Ireland runs PAYE, like Australia's PAYG withholding, but there are three deductions on your payslip instead of one, and the year runs differently.

The big mental shift is tax credits. In Australia the tax-free threshold means your first slice of income isn't taxed. In Ireland everything is taxed, then credits are subtracted from the bill. A single employee gets a €2,000 personal tax credit and a €2,000 employee (PAYE) tax credit in 2026 [3]. That's €4,000 off your tax, every year, as long as Revenue knows who you are and who you work for.

The 2026 numbers

Revenue notes that Budget 2027 was announced on 6 October 2026, so check the charts in January for next year's figures [3].

What that means on €60,000

As a rough illustration only, a single person on €60,000 for all of 2026, with no other income or reliefs:

• Income tax: €8,800 (20% of €44,000) plus €6,400 (40% of €16,000), minus €4,000 credits, is €11,200 [3].
• USC: about €1,333 [4].
• PRSI: about €2,540, blending the two 2026 rates [5].

That leaves roughly €45,000, or about €3,750 a month. Our cost of living guide shows how far that goes against Dublin rents.

Emergency tax: what it is and why it bites

Emergency tax applies when your employer doesn't have a Revenue Payroll Notification (RPN) for you. That happens if they don't have your PPSN, or your job isn't registered with Revenue [2].

The rules, straight from Revenue [1]:

• With a PPSN, weeks 1 to 4: you get a single person's rate band (1/52 of €44,000, so €846.16 a week at 20%), but no tax credits.
• With a PPSN, week 5 onwards: everything is taxed at 40%.
• Without a PPSN: everything is taxed at 40% from day one.
• USC: a flat 8% on all of it.

Here's what that does to €900 a week, using Revenue's own figures plus the normal 2026 rates [1][3][4].

By week 5 you're losing around €300 a week more than you should. It's not lost forever, but it's rent money you don't have.

Getting off emergency tax, step by step

Lots of Australians land in Dublin on a Working Holiday Authorisation and start work within days. The PPS number is usually the slow bit, so start it the week you arrive.

1. Get your PPS number. Apply through MyWelfare with photo ID, proof of address and a reason such as a job offer. Our PPS number guide covers the proof-of-address catch.
2. Give your PPSN to your employer as soon as you have it [2].
3. Register for Revenue myAccount at revenue.ie. You'll need your PPSN.
4. Add your job. If it's your first Irish job, go to "PAYE Services", then "Add Job or Pension Details". You'll need your employer's Tax Registration Number and your start date, which payroll or HR can give you [2].
5. Check your jobs and credits. If you have two jobs, use "Managing Tax" for the current year to split your credits and rate band between them [2].
6. Wait for the RPN. Your employer downloads it before the next payroll run and switches you to the cumulative basis [2].
7. Watch the next payslip. If you were on emergency tax, your employer can refund overpaid tax and USC through payroll once the cumulative RPN arrives [2]. If it doesn't appear, ask payroll before you ring Revenue.

Claiming the rest back

Your payslip refund only covers what payroll can see. Other money comes back by reviewing the year in myAccount, usually after it ends. Common items for Australians are:

• tax overpaid if you started work mid-year and your credits were never fully used
• qualifying health expenses, such as some GP and consultant bills, which get relief at the standard rate
• the rent tax credit, if you rent privately and qualify, which you claim through myAccount

Don't sit on it. Revenue's four-year rule means you can only claim for the last four years, and claims for 2022 must be made by 31 December 2026 [6]. Leaving Ireland? Review your final year before you fly, while you still remember your myAccount password.

Are you still taxed in Australia?

Moving to Dublin doesn't automatically end your Australian tax residency. The ATO applies its residency tests, starting with whether you still "reside" in Australia [9]. If you remain an Australian resident for tax, you must declare your worldwide income, including your Irish salary [9]. Once you stop being a resident, you don't need to include foreign income in your Australian return, and Australian interest and dividends are taxed by withholding as a final tax [9].

Ireland has its own test. You're Irish tax resident if you spend 183 days or more here in a calendar year, or 280 days across this year and last year together. Fewer than 30 days in a year never counts [7]. If you arrive late in the year planning to stay, you can elect to be resident in your arrival year, which gives you full tax credits [7].

The Australia–Ireland tax treaty

The double tax agreement was signed on 31 May 1983 and has applied to Irish income tax since 6 April 1984 [8]. It decides which country gets first go at taxing each type of income and how double taxation is relieved. For a salary earned in Dublin, Ireland taxes it first. If you're still an Australian resident too, the treaty and Australian law generally let you offset Irish tax against the Australian tax on the same income, rather than paying twice. Rental income from a flat in Brisbane stays taxable in Australia either way.

The social security agreement

The Australia–Ireland social security agreement has applied since 1 January 2006 [10]. If an Australian employer sends you to Dublin temporarily, a certificate of coverage can keep you in the Australian system for up to four years, so you aren't paying into both [10]. Hired locally? You pay Irish PRSI like everyone else. Those PRSI years can also help you qualify for pensions later, through the agreement.

Your Australian super stays put while you're away. An Irish employer won't pay into it, and you can't usually take it out early just because you've moved.

Confused about which country wants what? Ask in Cooee Ireland, our Facebook group for Australians in Ireland. Someone has usually just had the same payslip shock.

Common mistakes

• Starting work without a PPSN. It means 40% from your first euro [1].
• Assuming payroll registered your first job. For a first Irish job, you add it in myAccount yourself [2].
• Forgetting to split credits across two jobs. Hospitality workers on two rosters often get caught [2].
• Leaving without a review. The four-year clock keeps ticking after you fly home [6].
• Ignoring the ATO. Tell your Australian accountant, or the ATO, that you've moved, and work out your residency before your first Australian return.
