Calculating your Income Tax

What is a Tax Credit Certificate?

Your Tax Credit Certificate (TCC) sets out the following details for the tax year:

• tax credits, reliefs and rate band
• Universal Social Charge (USC) rates and rate band
• your Employment Identifier, which is a unique reference set by your employer for your employment.

You can view, print or download your TCC in the 'My Documents' folder in myAccount.

The 'My Documents' folder can be accessed on myAccount by following these steps:

1. Sign in to myAccount.
2. Click on the 'My Documents' folder on the top right-hand corner of the myAccount home page.
3. Select the specific year folder from the 'Summary' screen. 
4. View, download or print, the TCC from the 'My Documents' folder. 

You can request a new TCC by contacting Revenue via MyEnquiries. To do this, you should: 

1. Sign in to myAccount. 
2. Click 'MyEnquiries' on the top right-hand corner of the myAccount home page.
3. At the bottom of the page, click 'Add New Enquiry'.
4. In the 'Enquiry details' box, input your request for a new TCC. 
5. Confirm your email address. 
6. Click 'Submit enquiry'.

When you start your first employment in Ireland, you should go online, register for myAccount and register your new employment immediately. If not, you will have to pay Emergency Tax. A TCC will be available to you in 'My Documents' once you have registered your new employment.

A Revenue Payroll Notification (RPN) will be made available, on request, by your employer. The RPN shows your total tax credits, your tax and USC rate bands. Revenue will not give your employer a breakdown of the tax credits you have claimed, only the total amount. Your employer will use this to calculate your tax and USC.

Note

Your employer is obliged to register your new employment except where it is your first employment in the State. Your employer should register your employment with Revenue by requesting a new RPN for you.
