Tax credits and the standard rate cut-off point
Two settings on your Revenue record do more to determine your take-home pay than anything else: your tax credits and your standard rate cut-off point. Both are adjustable, both are frequently wrong after a job change, and neither will correct itself. This guide explains what they do and how to check them.
1. What a tax credit is
A tax credit reduces the income tax you owe, euro for euro. If your calculated tax is €7,000 and you hold €4,000 of credits, you pay €3,000. This makes credits straightforward to value: a €500 credit is worth exactly €500 to anyone with at least that much tax to pay.
That is different from a deduction or relief, which reduces the income being taxed. A €500 deduction is worth €100 to someone paying 20% on that slice of income and €200 to someone paying 40%. Both mechanisms exist in the Irish system, and confusing them leads to over-estimating what a relief is worth.
Most single employees hold two credits automatically: a personal tax credit and an employee (PAYE) tax credit. Irish Money Clock assumes a combined €4,000 for a single employee in 2026.
Credits are non-refundable. They can reduce your income tax to zero but not below it, so if your income is low enough that your calculated tax is less than your credits, the unused portion is simply lost. It does not carry over to the following year and it is not paid out.
2. The standard rate cut-off point
The cut-off point is the amount of income taxed at 20% before the 40% rate begins. It depends on your family circumstances and how you are assessed:
| Situation | Effect on the cut-off point |
|---|---|
| Single employee | The standard single figure. This calculator uses €44,000 for 2026. |
| Single Person Child Carer | An increase on the single figure, alongside the corresponding credit. |
| Married or civil partners, one income | A higher combined figure than the single amount. |
| Married or civil partners, two incomes | A higher combined figure again, with a transferable element and a portion that cannot be transferred between spouses. |
The transferable element is worth understanding for couples. Where one spouse earns considerably more than the other, moving the transferable portion of the rate band to the higher earner keeps more of their income at 20%. Where both earn above the individual limit, there is nothing useful to move.
3. How the two work together
The order of operations matters. The cut-off point decides how much of your income is taxed at each rate. Credits are then subtracted from the resulting figure.
Single employee, €50,000 gross, no pension
On a monthly payroll, one twelfth of both the cut-off point and the credits is applied each month. That is what makes deductions steady across the year rather than front-loaded, and it is why a mid-year change to either setting produces a visible adjustment in the following payslip.
4. Credits employees most often miss
These are the credits and reliefs that most commonly go unclaimed by PAYE workers. All are claimed through Revenue myAccount, and all can be backdated four years.
- Rent Tax Credit — for tenants in private rented accommodation. You will need the tenancy details and information about the landlord.
- Medical expenses relief — relief at the standard rate on qualifying unreimbursed health expenses, including GP visits, prescriptions, consultants and certain dental treatment. Keep receipts.
- Nursing home expenses — relief at your marginal rate, which makes this one of the most valuable reliefs available where it applies.
- Tuition fees — relief on qualifying third-level fees above a disregarded amount, available whether you pay for yourself or someone else.
- Single Person Child Carer Credit — a credit plus an increase in the cut-off point, for a parent or carer with whom a child resides for most of the year.
- Home Carer Credit — for jointly assessed couples where one spouse cares for a dependent person.
- Flat rate expenses — fixed deductions agreed for specific occupations, from nurses to shop assistants to engineers. Many people in listed occupations have never claimed theirs.
- Remote working relief — relief on a proportion of electricity, heating and broadband costs for days worked at home, where your employer has not paid the tax-free daily allowance.
5. Two jobs, or a job you have left
This is the single most common cause of a wrong deduction. Your credits and cut-off point are allocated to specific employments through myAccount. If the allocation does not match reality, the arithmetic is correct but the inputs are not.
- A ceased job still showing as active may be holding credits and rate band that your current employer cannot use, so you are taxed as if you had fewer credits than you do.
- Two active jobs with a default split may leave one employment with more rate band than it needs while the other pays 40% unnecessarily.
- A new job with no Revenue Payroll Notification in place will normally be taxed on the emergency basis. See our guide to emergency tax for how to fix it.
All three are corrected in the same place, and the correction usually flows through to your next payslip rather than requiring a claim at year end.
6. Checking your certificate
- Sign in to Revenue myAccount at revenue.ie.
- Open Manage your tax for the current year.
- Confirm your employments are listed correctly, and that any job you have left is shown as ceased.
- Review your credits, add any you are entitled to, and check how your rate band is divided between employments.
- Submit. Revenue issues an updated notification to your employer, normally reflected in the next pay run.
For prior years, request a Statement of Liability for each year you want reviewed. If you overpaid, the refund is paid directly to your bank account.
Irish Money Clock is an independent educational tool. The figures here illustrate how the rules generally work — they are not tax advice and they are not published by any public body. Rates, bands and credits change with each Budget, so confirm current official figures with Revenue and treat your own payslip and Revenue myAccount as authoritative.
Frequently asked questions
How far back can I claim a credit I missed?
Revenue allows claims for the four previous tax years. Reviewing several years at once is common and often produces a single refund covering all of them, so it is worth checking even if you only recently became aware of a credit.
What happens to my credits if I have two jobs?
You divide your credits and rate band between the employments through myAccount. If you leave the allocation at its default, one job may use credits you would rather apply elsewhere, or a job you have left may hold credits that cannot be used at all.
Do unused tax credits carry over to next year?
No. Credits are allocated per tax year and any part you could not use because your income was too low is lost at year end. They do carry forward between pay periods within the same year when PAYE is operated on the cumulative basis.
Is the Rent Tax Credit worth claiming?
For tenants in private rented accommodation it is one of the more valuable credits available, and it is claimed by fewer people than are eligible. You need details of the tenancy and the landlord, and you claim it through myAccount.
