Second or multiple jobs
What to do if you get a second job
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 Revenue Payroll Notification (RPN) for you.
Where your employer does not register your employment, you may use Jobs & Pensions service in myAccount to register the employment yourself.
To make sure that you pay the correct amount of tax, you can allocate your tax credits and rate band between your existing and new employments. You can do this in myAccount via PAYE Services or by contacting us. Each employer will then receive an RPN which instructs them on the correct deductions to make.
You might be receiving a pension from a former employer (occupational pension). If you are, for tax purposes this is taken to be your main employment. Any other jobs you have are treated as second or multiple jobs.
