Your First Job

If you are commencing employment in Ireland for the first time and have received your PPS No. you need to register for My Account with Revenue on

You will need the following details to register:

  • PPS number
  • Date of birth
  • Mobile number or landline number
  • Email address
  • Home address.

Revenue will match the details provided by you against details provided to them by the DSP. If all is in order they will issue a temporary password for my Account to you by post. This takes about five working days from the time you submit your registration request.

You will have to create a new password when you sign in to my Account for the first time. It is important to remember that the temporary password that they send you has an expiry date so you should sign in to my Account and create your new password as soon as you receive their letter. Otherwise you will have to register for myAccount again.

If your details do not match with those on file from the DSP, we will contact you and you may be required to have your details with the DSP updated. When this has been done you will have to submit your registration application for my Account again.

Step 1. Register your new job

Once you start work you must register the details of your new job with Revenue to get your Tax Credit Certificate (TCC) - see section 2, otherwise your employer will deduct emergency tax on your pay. The Jobs and Pensions service will guide you through the process of registering your details and setting up your new job.

You will need the following details to complete the job registration:

  • your new employers tax registration number
  • the date you started your new job
  • your staff number if you have been allocated one by your employer - this is also called a personnel, works or payroll number.
  • if you are receiving a benefit from the Department of Social Protection they may ask you for the weekly amount, if it is not already on our record.

They will also ask some questions to help determine your correct tax credits.

After your registration is complete and your job is set up, a TCC will issue notifying both you and your employer of your tax credits and rate band. You will be able to view your TCC on PAYE Anytime (available within my Account) within two working days.

Once your employer has received this notification, he or she can make the correct income tax deductions from your pay.

Step 2. What is a Tax Credit Certificate (TCC)?

A TCC is a certificate issued to you by Revenue outlining the tax credits you are currently claiming and your income tax rate band. It also shows your USC rates and thresholds.

Your employer will receive a separate certificate showing the total amount of your tax credits and rate band. Your employers certificate does not give a breakdown of the tax credits you have claimed only the total amount. The USC rates and thresholds are also shown on your employer's certificate.

If you don't have a PPS (Personal Public Service Number) you can apply for this at your local Social Welfare Office. They require certain documents and Proof of Identity to be brought to their offices before a PPS number can be issued.
