Tax credits and reliefs in Ireland

The two-minute version

• Tax credit = a fixed € amount that comes off your income-tax bill, euro for euro. Doesn't reduce USC or PRSI.
• Tax relief = you spent something (medical bills, rent, fees), and you get a percentage back — usually 20%.
• Personal Credit + Employee Credit are applied automatically. Everything else you have to claim.
• You have until 31 December 2026 to claim 2022, until 31 Dec 2027 to claim 2023, and so on. Miss the deadline, miss the money.
• Most claims take 5 working days to refund once submitted on myAccount.

How credits and reliefs actually work

Your gross salary is taxed in steps: PAYE (income tax), USC, PRSI. PAYE is the only one credits and reliefs touch. The calculation is roughly:

PAYE before credits − (default credits + extra credits + 20% × reliefs) = PAYE you actually pay

Default credits — Personal Tax Credit (€2,000 single / €4,000 jointly assessed) and Employee/PAYE Tax Credit (€2,000) — are baked in by Revenue. The rest are opt-in. Even if you've heard of them, they don't appear in your payslip until you tell Revenue you're claiming them.

How to file on Revenue myAccount

Revenue's myAccount is the PAYE worker's portal. You'll need a PPS number, an Irish address, and either a verified MyGovID or your Revenue identification details.

Real-time credits during the year

Some credits and reliefs can be claimed as you go, so they show up in your weekly/monthly pay rather than as a year-end refund:

1. Sign in at revenue.ie/myAccount
2. PAYE Services → Manage your tax for the current year.
3. Select the credit (e.g. Rent Tax Credit) and enter the details — landlord's name, RTB number, rent paid.
4. Revenue updates your tax credits and your employer applies them on the next payroll run (rolling restart of your tax position).

End-of-year claims (Statement of Liability)

For health expenses and any credits you didn't claim during the year, you file a separate income tax return for that year:

1. PAYE Services → Review your tax for the year(s) you want to claim.
2. Click Request Statement of Liability.
3. Click Complete Income Tax Return.
4. On the Tax Credits & Reliefs page, select the relevant credit (e.g. Health → Health expenses) and complete the form.
5. Submit. Refund (if any) usually lands in 5 working days.

Back-claiming for the previous 4 years

Revenue's 4-year rule means you can claim refunds for the four most recent completed tax years. Right now in 2026, that's 2022, 2023, 2024, 2025.

Each year is a separate filing. You cannot lump them together.

Step-by-step

1. Sign in to myAccount.
2. PAYE Services → Review your tax 2022–2025.
3. Pick the year. Request a Statement of Liability.
4. Click Complete Income Tax Return.
5. Add every credit and relief you were eligible for that year — rent paid, medical bills, single-parent status, dependents, etc.
6. Submit. Repeat for each of the four years separately.

Receipts: keep them for 6 years. Revenue can request proof on any claim during this window.

What credits don't do

• They don't reduce USC or PRSI. Those are calculated separately on your gross income.
• They're non-refundable. If your PAYE bill is €1,500 and your credits add up to €3,000, you owe €0 — you don't get the extra €1,500 paid out.
• They don't carry forward. Unused credit in one year doesn't roll into the next.

Checklist before you submit

• PPS number on hand
• Receipts/invoices for every relief amount you're claiming
• Landlord's name, address, RTB registration number (Rent Credit)
• Doctor/dentist receipts and Med 2 form for non-routine dental (Health Expenses)
• Confirmation your tenancy is RTB-registered if not rent-a-room/digs
• If married: spouse's PPS, decide whether jointly assessed

After this

Plug the credits into the calculator to see what your real take-home becomes — and what you might be due back across 2022–2025.
