Changed Jobs in Ireland? How to Claim Your Tax Refund 2025

Reviewed by: MyTaxRebate Team on 10 Mar 2026 | Authority: s.472 TCA 1997

Quick Answer

Changing jobs in Ireland creates two distinct tax risks: emergency tax on the new employer before your credit certificate is transferred, and a rate band mismatch during the transition period. Under s.112 TCA 1997 (Schedule E), each employer must deduct PAYE based on a Revenue-issued credit certificate. When you leave one employer and start another, your credits and standard rate band remain with the previous employer until Revenue transfers them to the new one. During the gap - which can last days or weeks - your new employer places you on emergency tax at 40%. Even after the certificate transfer, there may be a period where the correct cumulative position is not applied. Both overpayments are recoverable. The Employee Tax Credit (s.472 TCA 1997, €1,875 in 2025) and any unused reliefs from both employment periods can be included in a single year-end claim covering all four claimable years (2022 - 2025). MyTaxRebate reviews your full employment history and submits the consolidated recovery claim to Revenue.

Key Facts at a Glance

• ✓Your tax credit certificate stays with your previous employer until Revenue transfers it to your new employer - this process typically takes days to weeks.
• ✓During the transition, your new employer places you on emergency tax at a flat 40% deduction on all income.
• ✓Emergency tax from prior years is recoverable for up to four years - 2022, 2023, 2024, and 2025.
• ✓A mid-year job change can also affect your standard rate band allocation - income from the new employer may be incorrectly taxed at 40% even after the emergency tax period ends.
• ✓Any unused credits from the period between jobs (where income dropped to zero) also convert to a refund.
• ✓Claims cover all employment periods within the four-year window - 2022 closes on 31 December 2026.

What Happens to Your Tax Credits When You Change Jobs

When you leave a job, Revenue continues to have your full annual credit and rate band allocation assigned to your previous employer in its system. Your new employer starts completely fresh - it has no credit information for you until Revenue issues a new certificate. In practice, this means your first pay period with the new employer almost always involves emergency tax. The emergency tax rate is 40% on all income, regardless of your actual rate or income level.

PAYE Modernisation (introduced January 2019) was designed to make the transfer faster by linking employer payroll submissions in real-time. However, the credit certificate transfer still requires Revenue to process the new employer's registration and your PPS number before issuing the certificate. This typically takes three to seven working days for workers who provide their PPS number immediately on starting. For workers who take time to register, emergency tax can persist for several weeks.

The Transition Period Overpayment

Once your credit certificate is issued to the new employer, the deduction rate is corrected going forward. However, the overpayment from the emergency tax weeks is not automatically corrected by Revenue - it must be claimed separately. In addition, the cumulative tax position for the year (based on total income from both employers) must be reviewed to ensure the rate band was correctly applied across the full year. If you moved from a lower-paying to a higher-paying role (or vice versa), your rate band allocation may have shifted in a way that produces either a further overpayment or a small underpayment.

The Mechanism Behind Job-Change Overpayments

Under s.112 TCA 1997, employment income from any PAYE source is assessed as Schedule E income and your tax liability is calculated cumulatively across the full year. When you change jobs, Revenue issues a new tax credit certificate to your new employer. However, there is almost always a period at the start of the new job where the certificate has not yet been issued - or where the credit has been issued but not yet processed into the payroll system. During this gap, many employees are placed on emergency tax at 40%, regardless of their actual income level. The Employee Tax Credit under s.472 TCA 1997 (€1,875) and Personal Tax Credit (€1,875) should reduce your effective rate significantly below 40% for most income levels, so emergency tax typically creates a substantial overpayment.

The Rate Band Issue When Changing Jobs

Even after emergency tax ends, a job change during the year can create a rate band overpayment. Revenue's standard rate band (€42,000 in 2025 for a single person) is issued to your employer and divided across pay periods. If you changed jobs in the middle of the year, your previous employer applied a portion of the rate band for the period you worked there. Your new employer may initially apply the full rate band - or may not receive full details of the year-to-date income from your old employer - potentially resulting in a discrepancy in how the annual band was used across the year. A year-end review corrects this and identifies any resulting overpayment.

Combining Job-Change Overpayments with Additional Reliefs

When reviewing a year where you changed jobs, MyTaxRebate also identifies all additional reliefs available for that year: medical expenses, WFH relief, flat-rate expenses for your occupation(s), and any other applicable credits. In some cases, a year involving a job change also involved a period of reduced income or unemployment between the two positions - both of which further affect your tax position and increase the refund entitlement. A comprehensive review for all four backdatable years (2022 - 2025) ensures nothing is missed.

When to Act for a Job-Change Refund

Job-change overpayments can be recovered for any year from 2022 to 2025, subject to Revenue's four-year backdating limit. The 2022 tax year closes permanently on 31 December 2026. Workers who changed jobs in 2022 and were on emergency tax during that transition have until that date to submit a claim for that year. A four-year review covering all years in the window ensures every job-change overpayment period is identified and included, alongside any additional reliefs available for each year.

MyTaxRebate reviews your employment history across all four claimable years and identifies every job-change overpayment period. All applicable years and additional reliefs are included in one consolidated Revenue claim, managed entirely on your behalf.

Tax Scenarios

Common Mistakes To Avoid

• ✗Providing your PPS number to the new employer only after your first pay date: This is the primary cause of extended emergency tax. Provide your PPS number to your new employer before your first pay date to minimise the emergency tax period.
• ✗Assuming the old employer handled the credit transfer: Credit transfer from old to new employer happens through Revenue, not through your employers. Your old employer has no involvement - it is your responsibility to ensure Revenue has your new employer's details.
• ✗Not claiming if the gap was short: Even a few days of emergency tax can generate a meaningful overpayment - and when combined with additional reliefs and a year-end calculation, the total refund is often larger than expected.
• ✗Not reviewing prior years where job changes also occurred: If you changed jobs in 2022, 2023, or 2024 as well as 2025, each of those years should be reviewed - the same overpayment pattern often recurs.

When This Does Not Apply
