Settlement Agreements Explained – What to Know Before You Sign
If your employer has offered you a settlement agreement, you're probably dealing with a stressful situation and facing a decision under time pressure. This guide explains what a settlement agreement actually is, what rights you're giving up by signing, which payments are tax-free, and — critically — what to watch out for before you put your name to anything.
The most important thing to know upfront: you cannot legally sign a settlement agreement without independent advice from a qualified solicitor. This isn't a formality — it's a legal requirement, and your employer must contribute to the cost.

A settlement agreement — previously called a compromise agreement — is a legally binding contract between you and your employer. In return for a financial payment, you agree to waive your right to bring most employment tribunal claims against your employer.
Settlement agreements are used in a wide range of situations: redundancy, dismissal, disputes about pay or treatment, or simply as a way to bring an employment relationship to an agreed end without either side going to tribunal. They are not an admission of wrongdoing by either party — they are a commercial resolution.
Once signed, a settlement agreement is final and binding. You cannot generally reopen claims that are listed in the agreement, even if you later discover information that would have changed your decision. That is why taking proper legal advice before signing is non-negotiable.
What Claims Does Signing Away?
A settlement agreement must specifically list the claims being waived — a blanket "all claims" waiver is not legally sufficient. Common claims that are waived include:
- Unfair dismissal
- Wrongful dismissal
- Discrimination claims (race, sex, age, disability, religion, sexual orientation)
- Claims for unpaid wages or holiday pay
- Breach of contract claims
- Redundancy pay disputes
However, some claims cannot be waived by a settlement agreement regardless of what it says:
- Personal injury claims not known at the time of signing
- Accrued pension rights
- Claims arising after the date of the agreement
- Certain whistleblowing claims
The Legal Advice Requirement
A settlement agreement is only legally valid if you have received independent legal advice from a qualified solicitor, barrister, legal executive, or trade union representative. This is a statutory requirement under the Employment Rights Act 1996 — without it, the agreement cannot waive your tribunal rights.
Your employer must contribute to the cost of your legal advice. The amount they contribute varies — typically £250 to £500 for a straightforward settlement, more for complex cases. If the employer's contribution doesn't cover the full cost, you may need to top it up, though many solicitors will complete a standard settlement agreement review within the employer's contribution.
The legal fees contribution paid directly to your solicitor is tax-free with no limit — it does not count toward your £30,000 termination payment exemption.
How Settlement Payments Are Taxed
This is where many employees — and some employers — get it wrong. Different elements of your settlement package are taxed under different rules.
Settlement Agreement — Tax Treatment by Component
| Payment type | Tax treatment | Counts toward £30,000? |
|---|---|---|
| Statutory redundancy pay | Tax-free within £30,000 limit | Yes — counted first |
| Enhanced redundancy pay | Tax-free within remaining £30,000 headroom | Yes |
| Ex-gratia / compensation for loss of employment | Tax-free within remaining £30,000 headroom | Yes |
| Pay in lieu of notice (PILON) | Always fully taxable as earnings | No — sits outside the exemption entirely |
| Accrued holiday pay | Always fully taxable as earnings | No |
| Legal fees contribution to solicitor | Tax-free — no limit | No — separately exempt |
The £30,000 Tax-Free Threshold in Practice
The £30,000 exemption applies to qualifying termination payments — amounts paid to compensate you for the loss of your employment, rather than for work you have done. The threshold has been unchanged since 2018.
Statutory redundancy pay counts toward the threshold first. If your statutory redundancy pay is, say, £8,000, you have £22,000 of the threshold remaining for enhanced redundancy pay and ex-gratia compensation. If the combined total of all these elements exceeds £30,000, the excess is taxable at your marginal rate.
Important: PILON does not reduce or use up any of the £30,000 threshold. It is always taxable as a separate matter, regardless of how the agreement is structured or labelled.
Employer National Insurance on Your Settlement
Your employer also pays employer NIC at 13.8% on any part of your termination payment that exceeds the £30,000 threshold. This is a cost to your employer — it is not deducted from your payment — but it affects the total cost of your settlement to them.
A settlement of £60,000 costs your employer £60,000 to you plus 13.8% employer NIC on the £30,000 above the threshold (£4,140) — a total cost of £64,140. This is worth understanding in negotiations, as your employer may factor in their NIC liability when making or responding to offers.
How Long Do You Have to Decide?
Acas guidance recommends a minimum of 10 calendar days to consider a settlement offer before being asked to sign. Your employer should not pressure you to sign immediately or within a day or two of receiving the offer.
If you need more time to take advice, negotiate terms, or simply think through your options, you are entitled to ask for it. A reasonable employer will accommodate this. If you feel you are being pressured to sign unreasonably quickly, this may be relevant to any claim you have — and should be something your solicitor is aware of.
What to Negotiate — and What to Watch For
Many employees assume the first offer is final. It rarely is. Common areas to negotiate include:
- The total payment — particularly if you have strong grounds for an unfair dismissal or discrimination claim, the settlement should reflect the value of those claims
- The reference wording — settlement agreements often include an agreed reference. Make sure the wording is something you are comfortable with before signing
- Garden leave vs PILON — if you haven't yet served your notice, whether you work it, take garden leave, or receive PILON has different tax and employment implications
- Post-termination restrictions — some agreements seek to add or strengthen restrictive covenants. Be alert to any new restrictions being inserted that weren't in your original contract
- Confidentiality clauses — most settlements include confidentiality provisions. Understand exactly what you are and are not permitted to say about the circumstances of your departure
- Outstanding bonus or commission — make sure any bonus, commission, or share scheme payments that have accrued or are due are addressed explicitly in the agreement
Red Flags to Watch For
- Being given less than 10 days to sign
- A legal fees contribution so low it is impossible to get proper advice
- New or extended post-termination restrictions that weren't in your original contract
- Vague or poorly worded reference provisions
- A payment structured entirely as PILON to avoid the £30,000 exemption applying to any ex-gratia element
- Waiver of claims that are particularly valuable given your circumstances (for example, a discrimination claim if you have clear evidence)
If You Reject the Offer
You are under no obligation to accept. If you reject the offer, your employment situation continues as before — in most cases, the fact that a settlement was discussed is "without prejudice" and cannot be used against you in tribunal proceedings.
Rejecting a settlement does not automatically mean you will face dismissal — though in many cases the employer is offering a settlement precisely because they are planning to end the employment anyway. Your solicitor can advise on the likely alternative outcomes and the relative value of settling versus pursuing a claim.

Frequently Asked Questions
Can I be forced to sign a settlement agreement?
No — settlement agreements must be entered into voluntarily. You must be given a reasonable period to consider the offer (Acas recommends at least 10 days) and must receive independent legal advice before signing. Signing under duress may affect the validity of the agreement.
What if I don't agree with the settlement amount?
You can negotiate. The first offer is rarely final, particularly if you have strong tribunal claims. Your solicitor can advise on the strength of your position and help you negotiate improved terms.
Can I discuss the settlement with anyone?
Most settlement agreements include confidentiality provisions preventing you from disclosing the terms. However, you can always discuss it with your solicitor, and usually with your spouse or civil partner. Check the specific wording of your agreement carefully.
What happens to my pension?
Accrued pension rights cannot be waived by a settlement agreement. Your employer must continue pension contributions up to your termination date. Check your agreement to ensure pension entitlements are addressed, and take separate pensions advice if you have a significant pension entitlement.
Is the settlement confidential?
Almost always — most settlement agreements include mutual confidentiality clauses. This typically prevents you from disclosing the amount, terms, or circumstances of the settlement. Breaching a confidentiality clause can result in you having to repay some or all of the settlement payment.
