Quick answer
- A tax credit reduces Income Tax euro for euro, while a rate band decides how much income is taxed at 20% before 40% begins.
- Your Tax Credit Certificate shows your credits, rate band, USC details, employment identifier and tax basis for the year.
- Payroll receives totals and cut-off points through an RPN; Revenue does not give the employer a breakdown of the credits you claimed.
- Changing an allocation between jobs changes where PAYE is deducted during the year, not the total annual entitlement by itself.

Tax credits and rate bands do different jobs
| Payroll item | What it does | 2026 single-employee reference |
|---|---|---|
| Tax credit | Reduces calculated Income Tax euro for euro | €2,000 Single Person plus up to €2,000 Employee Tax Credit |
| Standard-rate band | Sets how much income is taxed at 20% | €44,000 annual general band |
| Cut-off point | The period or job-specific share of the band available to payroll | May be lower if split between jobs |
| Tax basis | Controls whether payroll uses cumulative, Week 1/Month 1 or emergency treatment | Shown through Revenue payroll records |
What your Tax Credit Certificate shows
Your TCC is the employee-facing record in the My Documents area of myAccount. It sets out tax credits, reliefs, the Income Tax rate band, USC rates and bands, and the employment identifier. Check that the correct employments are listed and whether the certificate is cumulative or Week 1/Month 1.
TCC versus Revenue Payroll Notification
| Record | Who sees it | What it contains |
|---|---|---|
| Tax Credit Certificate (TCC) | You | Credits, reliefs, rate bands, USC details, basis and employment identifier |
| Revenue Payroll Notification (RPN) | Your employer/payroll | Total credits, Income Tax and USC cut-off points, basis, relevant prior pay/tax and any exemptions |
| Payslip | You and employer | Pay inputs and deductions actually processed for that payday |
Revenue says the employer receives only the total tax credits, not a breakdown of the personal credits or reliefs you claimed. Payroll should request the latest RPN before calculating pay.
How allocation between jobs changes a payslip
If all credits and rate band remain with a main job, a second job may have no 20% band or tax credits allocated and can therefore show 40% PAYE from the first euro. This is not automatically Emergency Tax. Revenue allows you to divide the credits and bands in Manage your tax for the current year, but moving an allocation does not reduce the combined annual Income Tax liability by itself.
| Allocation choice | Likely payslip effect | Important caution |
|---|---|---|
| Everything with main job | Main-job PAYE is lower; second job may be taxed at 40% | High PAYE on the second job can still be correct |
| Split based on estimated pay | Deductions can be spread more evenly | Revenue may issue revised records on Week 1 basis |
| Transfer unused amounts | Another job can use available credits/band | Some job-specific credits cannot be split |
What to do when your credits or band look wrong
- Download the current TCC. Do not compare a 2025 certificate with a 2026 payslip.
- Check every active and ceased employment. An old active job can affect allocation or delay a refund review.
- Compare the payslip and Revenue pay details. Confirm that gross/taxable pay and deductions were reported correctly.
- Update permitted current-year claims or allocations in myAccount. Use MyEnquiries where the service does not offer the required change.
- Allow payroll to retrieve the updated RPN. The employer cannot safely replace Revenue’s figures with a verbal amount from an employee.
Frequently asked questions
What is a Tax Credit Certificate in Ireland?
It is Revenue’s employee-facing record of your tax credits, reliefs, rate band, USC details, employment identifier and tax basis for a tax year.
Where can I find my Tax Credit Certificate?
Revenue says it can be viewed, downloaded or printed from the My Documents folder in myAccount.
What is a Revenue Payroll Notification?
An RPN is the record made available to an employer with the totals, cut-off points and basis needed to calculate Income Tax, USC and any applicable LPT.
Can my employer see which tax credits I claimed?
Revenue states that the employer receives the total credits, not the breakdown of the personal credits and reliefs claimed.
Why is my standard-rate band lower than €44,000?
The band may be split between employments, adjusted for another income or assessment, or based on personal circumstances. Use the amount on your current TCC rather than assuming the general single band.
Can I split tax credits between two jobs?
Yes. Revenue allows credits and rate bands to be divided through Manage your tax for the current year. This changes where tax is deducted, not the overall entitlement by itself.
Can unused tax credits be refunded or carried into next year?
No. Credits can reduce Income Tax paid, but Revenue says unused credits cannot be refunded as cash or carried into another tax year.
What tax credits can I claim?
That broad question depends on personal circumstances and belongs in the Irish Tax Credits guide. This page focuses on how approved credits and bands reach PAYE payroll.
