I am leaving my job, what must I do?

When you leave a job, it is important to get a form T21 from your employer. This is a Leaving Certificate which has three parts. Part 1 is sent to the IncomeTax Division to inform us that you have ceased employment, parts 2 and 3 are given to you to hand to your new employer to inform them of your current tax code. Your new employer should retain part 2, and complete and return part 3 to the Income Tax Division. This informs us that you have started a new job.

If you do not get a form T21 or lose it, you will not have details of your current ITIP code.
