Detailed Guidance
As a general rule, a termination payment up to £30,000 is tax-free. This tax-free slice is inclusive of any redundancy payment. Care should be taken to ensure that other types of taxable payments, such as holiday pay, are not wrongly rolled into a termination payment. Similarly, if there is notice pay has not be paid and taxed, this may result in a tax charge on some or possibly all of the the first £30,000.
Most other payments, with a few exceptions, will be subject to PAYE deductions, i.e. income tax and employee national insurance.

who pays the tax on a settlement agreement?
What qualifies as a tax-free ‘termination payment?
You may see a term called ‘Post Employment Notice Pay’, or PENP for short, used in a settlement agreement. PENP is subject to the usual PAYE deductions.
If tax is due will my employer deduct it from the settlement?
If some or all of the payments are taxable, usually, the employer should deduct the appropriate income tax and any applicable employee national insurance, before making the payment. If the settlement agreement wrongly provides for a payment to be paid tax-free, and the tax authority (HMRC) discover this later, the employer will be asked to make good the situation by paying the tax and national insurance due, along with interest and possibly fines and/or penalities. While good employers will try and make sure the correct tax is deducted, and get it right most of the time, mistakes can happen. To protect themselves, employers usually include a clause in the settlement agreement that says the employee will pay the employer a sum equal to any excess tax and associated interest and/or fines or penalties HMRC demands from the employer.
