Quick Answer
Most Leaving Cert students who take summer jobs will overpay PAYE tax because Revenue allocates the full year's tax credits - the Employee Tax Credit (€1,875 under s.472 TCA 1997) and Personal Tax Credit (€1,875) combined worth €3,750 - regardless of how many months you actually work. A student who earns €5,000 over a 10-week summer job will have most or all of that PAYE withheld refunded, because the annual credits easily exceed the tax due on a summer wage. The key is to: (1) register the job with Revenue before starting to avoid emergency tax; and (2) submit a review the tax position in the Revenue system after the year ends to claim any refund. MyTaxRebate can assist with this review at no upfront cost.

How PAYE Works for Student Workers
When a student starts working in Ireland for the first time, they become a PAYE worker under s.112 TCA 1997. Their employer deducts income tax, Universal Social Charge (USC), and Pay Related Social Insurance (PRSI) from each wage payment and remits these to Revenue through the real-time reporting (RTR) system. The amount of income tax deducted depends on whether the employer has received a tax credit certificate from Revenue for the worker. The credit certificate tells the employer the worker's tax credits and standard rate cut-off, allowing the correct amount of PAYE to be deducted each pay period.
For a student working a 10-week summer job earning €500 per week (€5,000 total), the annual income is €5,000. The combined Employee Tax Credit (€1,875) and Personal Tax Credit (€1,875) of €3,750, at a 20% tax rate, effectively give a tax-free threshold of €18,750. Since €5,000 is well below this threshold, the student owes no income tax for the year. However, the employer will still deduct PAYE each week on a cumulative basis - applying the credits evenly across all weeks of employment. Where the employment covers only some weeks in the year, the credits for the non-working weeks remain unused and the student is owed a refund of any PAYE that was deducted.
How to Avoid Emergency Tax on a Summer Job
Emergency tax is the most common and avoidable reason students overpay PAYE tax. It arises when an employer does not have the worker's tax credit certificate before processing the first payroll. Emergency tax applies a flat 40% rate on all income with no credits. For a student earning €500/week, emergency tax deducts €200/week rather than the correct amount of approximately zero per week (given the high credit value relative to summer income). The solution is to register the employment in the Revenue system before the first payslip is processed: log into the Revenue system, go to "Jobs and Pensions", and add the employer's tax registration number. Revenue will issue a credit certificate to the employer within a few days, and the first payslip will be correctly taxed.
Claiming the Refund After the Summer Job
After the tax year ends, submit a review the tax position through the Revenue system for the year in question. Revenue calculates the correct annual tax position based on the full year's income (only the summer wages) and applies the full year's credits (€3,750 for 2025). Where the credits exceed the tax due on the summer wages, the difference is refunded. For a student earning €5,000 who had any PAYE deducted, the full amount is typically refunded plus a small additional amount. Even where the employer correctly deducted PAYE on a cumulative basis (reducing the overpayment), a year-end review often confirms a residual refund from unused monthly credits in the non-working period.

Setting Up a Bank Account and Receiving the Refund
Before submitting the review, register an Irish bank account with Revenue in the Revenue system under "Manage My Tax - Add Bank Account". Revenue pays refunds electronically to the registered IBAN. Without a registered account, Revenue will issue a cheque by post, which takes significantly longer. For most students, a current account with any Irish bank or credit union qualifies. Revenue typically processes the review and issues the refund within 5 - 15 working days of submission.
How Emergency Tax Affects Students Starting Work
Emergency tax under s.112 TCA 1997 is the most significant issue for students starting their first job. When a student begins work and their employer does not have a tax credit certificate issued by Revenue, the payroll system defaults to emergency tax - deducting income tax at 40% on all income with no credits applied. For a student earning €400/week during the summer, emergency tax deducts approximately €160/week in income tax, compared to the correct deduction of approximately €0 - €25/week (depending on total earnings and the Personal Tax Credit allocation).
The fix is straightforward: log into the Revenue system and add the new employer under "Jobs and Pensions" using the employer's tax registration number. Revenue issues a credit certificate to the employer within 1 - 3 working days. Once received, correct PAYE deductions apply from that payroll run onwards. However, the emergency tax deducted during the weeks before the certificate was received is not automatically refunded - it must be claimed through a year-end review for the relevant year.
The Tax Credits Available to Students Working in Ireland
Every person working in Ireland, including students, is entitled to the Personal Tax Credit (€1,875 per year) and, for PAYE employees, the Employee Tax Credit (€1,875 per year under s.472 TCA 1997). Together these reduce the annual tax liability by €3,750. For a student working a summer job earning €8,000 total, the combined credits exceed the income tax liability on that income - meaning the student may have paid no income tax at all, and any tax deducted through emergency tax is fully refundable.
Students who work during the school term as well as in the summer should be aware that their total annual income is what determines the tax liability for the year. If total earnings across all employers in a year are below the amount covered by credits (€3,750 in credits can absorb all income tax on approximately €18,750 of income at the standard rate), a full refund of any PAYE deducted is available through the Revenue system. Students who had multiple jobs in the same year should review all employments together in the same the Revenue system year-end submission to get the correct combined picture.
Health expenses paid personally by the student (GP fees, prescriptions, dental costs beyond the standard plan) qualify for 20% relief under s.469 TCA 1997 and can be included in the same the Revenue system review. If the student also pays rent for college accommodation from their own income, the rent tax credit (€1,000/year for a single person renting in the private market) can be claimed for years where they were personally paying rent to an unconnected private landlord.

Tax Scenarios
Employee with missing credits
A PAYE worker finishes the year with standard credits not fully reflected in payroll. The corrected annual calculation reduces liability by €940, creating a refund once the file is reviewed properly.
Worker who changed jobs
An employee changes employer twice in one year and payroll deductions do not align neatly across the record. A full review shows €780 of overpaid tax after the final year-end reconciliation.
Part-year worker with reliefs still unused
A worker has employment income for only part of the year and also has allowable reliefs that were never fully used. The combined review produces a refund of about €1,120 rather than a smaller payslip-only correction.
Common Mistakes To Avoid
- ✗Not registering the job in the Revenue system before starting - causes emergency tax at 40%, creating a significant overpayment that must be recovered later.
- ✗Assuming the refund will arrive automatically - Revenue does not automatically issue refunds for PAYE overpayments; a review the tax position must be submitted through the Revenue system.
- ✗Not registering a bank account before submitting - causes Revenue to issue a cheque by post, which adds several weeks to refund timing.
- ✗Waiting too long to claim - prior year refunds can be claimed for up to four years, but acting promptly avoids the risk of forgetting or missing the window.

How do I avoid emergency tax on my summer job?
Register the employer in the Revenue system before your first payslip is processed. Add the employer under "Jobs and Pensions" using their tax registration number. Revenue issues a credit certificate to the employer and correct PAYE is deducted from day one.
How do I claim back tax from a summer job?
After the tax year ends, log into the Revenue system and submit a review the tax position for the relevant year. Revenue recalculates your position and issues any refund to your registered bank account within 5 - 15 working days.
At what income does a student start paying tax?
With both the Employee Tax Credit and Personal Tax Credit (€3,750 combined at 20%), the effective income threshold is approximately €18,750 per year. Earnings below this level typically result in zero net income tax for the year.
How long does the refund take to arrive?
Revenue typically processes the review and issues the refund within 5 - 15 working days. Register a bank account in the Revenue system before submitting for electronic transfer. Without a registered account, a cheque is issued by post.
Can I claim for summer jobs from previous years?
Yes. The four-year backdating rule means you can claim for 2022, 2023, 2024, and 2025 in 2025. Any summer job in those years with unclaimed refunds can be reviewed through the Revenue system.
