PAYE if I have 3 day a week permanent job and 3month contract with 2 days a week?

Each job will take off PAYE for the income earned, at the end of the tax season when you file you will most likely find that you will receive a large refund because of the way the PAYE is calculated.

Thank you. Thus permanent job will be taxed at normal rate and contract at 25 percent? This just does not seem right? Together both won't even tally to 12k.

When PAYE is calculated it is assumed that you are working a full year and so the period is based on the annual tables and then divided by 12. If you want to avoid this your employers can apply for a tax directive. to deduct less tax.
