Salary Sacrifice

[JeremyE]

I have just retired after 23 years with my employer, I had asked for 60% of the last 3 months of wages to be salary sacrificed into my pension including 100% of my final exit bonus. They paid the normal wage part into my pension but forgot to do the final bonus which amounted to just under £10,000. This means I have now paid tax and NI on that amount. They have admitted their mistake but say there is nothing they can do, so essentially I am quite a bit out of pocket, is there anything I can do? Any advice would be appreciated.

Hi, Payroll manager posting.

Did they confirm in writing they would pay the bonus into your pension? or are there any written company policies regarding sacrificing?

Regardless, I would suggest you and ask them to roll back and recalc the payroll for the month. Then offer to return the Net pay to them. It a hassle but most payroll software has this facility. It's their mistake and youve paid the price heavily in tax/NI!!
You may struggle to receive a revised P45, though they could easily confirm the revised earnings in writing. In recalculating the payslip they would need to send a revised RTI file to HMRC who can advise your new employer.

Whether it's an unlawful deduction of wages would very much depend on the answer to the first question.
