Temporary change to job

I am currently on secondment to another role within the same NHS Trust. This is for 7 months only and then it will end. How do I update my details so it that reflects that yes my salary has increased but it is only temporary?

Hi Anna Nash,

To avoid an overpayment at the end of the tax year it would be appropriate to contact the helpline with a new estimated income for the year.

Thank you.
