Hi,
When you’re leaving a job, whatever payments the company makes to you are called “Termination Payments” by HMRC, regardless of whether they are redundancy payments, compensation for unfair dismissal, pay in lieu of notice (commonly abbreviated to PILON), holiday pay, or simply any wages owed.
As long as the payment is made because your employment is being terminated, for whatever reason, then the tax laws covering Termination Payments will apply:
Tax on termination payments
Whether you are entitled to the first £30000 tax free, will depend on how the settlement agreement is made up.
Thank you.
