The £30,000 Tax-Free Rule on Settlement Agreements

The basic rule: section 403 ITEPA 2003

Under section 403 of the Income Tax (Earnings and Pensions) Act 2003, the first £30,000 of a termination payment is exempt from income tax. This has been the rule since 1988 and the threshold has not increased in decades — meaning it covers a smaller proportion of typical settlements every year.

Importantly, this exemption applies to income tax only. National Insurance contributions on the excess (above £30,000) are also payable at 2% — for both employee and employer — following changes introduced in April 2020.

What qualifies for the £30,000 exemption?

The following types of payment can be included within the £30,000 tax-free pool:

• Statutory redundancy pay — always qualifies
• Enhanced redundancy pay — qualifies up to the £30,000 combined limit
• Ex-gratia payments — payments made without any contractual obligation, as compensation for loss of employment
• Compensation for loss of office — genuine compensation (not pay for work done)
• Some injury to feelings awards — where they relate to a non-employment matter (complex area — get advice)

What does NOT qualify — always taxable

The following are always subject to income tax and NI regardless of the £30,000 exemption:

• Payment in lieu of notice (PILON) — see below for the critical change in 2018
• Holiday pay — accrued holiday is earnings, always taxable
• Salary or wages owed — any arrears of pay are earnings
• Bonus payments — contractual bonuses are earnings
• Payments for restrictive covenants — always taxable as employment income
• Benefits in kind — continued use of a company car, for example

The 2018 PILON rule change — critical

Before April 2018, whether PILON was taxable depended on whether there was a contractual PILON clause. Without a clause, a payment in lieu of notice was sometimes treated as damages (tax-free within the £30,000 limit).

This changed completely in April 2018. Now, all PILON payments are treated as taxable earnings regardless of whether a PILON clause exists in the contract. HMRC introduced the concept of "Post-Employment Notice Pay" (PENP), which calculates the taxable element of any payment that relates to an unworked notice period.

This is one of the most commonly misunderstood areas of settlement agreement tax — do not assume any element of notice pay is tax-free.

How the £30,000 limit applies in practice

The exemption applies to the total of all qualifying payments, not per payment type. Example:

Can you increase the tax-free element?

There are legitimate ways to structure a settlement to maximise the tax-free amount:

1. Pension contributions

Employer contributions to your pension scheme from a settlement payment are generally not subject to income tax and NI (subject to annual allowance limits). This can be highly tax-efficient for higher earners. Requires agreement from the employer and must be structured correctly.

2. Correct categorisation

Ensuring payments are correctly categorised in the agreement matters. An experienced solicitor will review the structure to ensure the maximum qualifying amounts sit within the tax-free pool.

3. Avoiding contractual payments in the termination payment

Payments that the employer was already contractually obliged to make (like an accrued bonus) should not be labelled as part of the settlement's ex-gratia element — they are taxable regardless, and conflating them can create compliance issues.

NI on termination payments

Since April 2020, employers must pay Class 1A NI at 13.8% on termination payments above £30,000. Employees pay 2% employee NI on the excess above £30,000. This makes very large settlement payments somewhat less generous in net terms for both parties, and may affect negotiation dynamics.

The £30,000 exemption — common misconceptions

Despite being a well-known rule, the £30,000 tax-free exemption is surrounded by persistent misunderstandings. Getting these wrong can result in unexpected tax bills — or, in the employer's case, HMRC penalties for incorrect payroll treatment.

Misconception 1: "The entire settlement is tax-free up to £30,000." This is wrong. Only qualifying termination payments sit within the £30,000 pool. Notice pay (PILON), accrued holiday, bonus, and salary arrears are always taxable regardless of the £30,000 limit. The exemption applies only to the non-earnings elements of a settlement — genuine compensation for loss of employment.

Misconception 2: "My employer can just label everything as 'ex-gratia' and it will be tax-free." HMRC looks through labels to substance. A payment that is in reality compensation for wages earned, bonus due, or notice that should have been worked cannot be recharacterised as a tax-free ex-gratia payment. HMRC can challenge the categorisation years after the payment is made.

Misconception 3: "I can receive multiple £30,000 exemptions in the same tax year from different employers." In theory, the exemption applies per employment — not per tax year. However, where payments from the same employment are split across multiple payments or documents, HMRC will aggregate them. Payments from genuinely separate, unrelated employments each attract their own £30,000 pool.

Misconception 4: "Injury to feelings payments are always tax-free." Only injury to feelings payments that relate to a non-employment matter (e.g. a disability that existed before employment) are potentially tax-free. Injury to feelings awards arising from workplace discrimination are generally treated as taxable employment income. This is a complex area where professional advice is essential.

What counts toward the limit: Statutory redundancy pay, enhanced redundancy pay, ex-gratia compensation for loss of office, and certain non-contractual payments all count toward the £30,000 pool. Once the pool is used up, any remaining qualifying payment is taxable at your marginal rate.

Notice pay taxation after April 2018

The April 2018 reforms introduced the concept of Post-Employment Notice Pay (PENP) to end the longstanding practice of treating non-contractual PILON payments as tax-free damages. Under the PENP rules, a defined portion of any termination payment that relates to an unworked notice period is treated as taxable earnings — regardless of whether the employment contract contains a PILON clause.

How PENP is calculated (in plain English): HMRC's formula determines what you would have earned during your notice period had you worked it, then taxes that amount as earnings. Any amount paid above PENP (the genuine compensation element) can sit within the £30,000 tax-free pool.

A worked example:

• Employee's basic monthly salary: £5,000
• Contractual notice period: 3 months
• Post-employment notice pay (PENP): £5,000 × 3 = £15,000 — taxable as earnings
• Ex-gratia compensation: £35,000 — first £30,000 tax-free, £5,000 taxable
• Statutory redundancy pay: £6,000 — but the £30,000 pool is already used by ex-gratia, so this is taxable

In this example, £15,000 of notice pay and £5,000 of ex-gratia and £6,000 of redundancy pay are all taxable. Only £30,000 (the first £30,000 of ex-gratia) is tax-free. The total taxable element is £26,000 — significantly more than many employees expect.

The PENP calculation becomes more complex when employees have variable pay, bonuses, or benefits included in their remuneration. If your pay is not straightforwardly monthly salary, ask your solicitor or a tax adviser to model the PENP calculation before finalising the settlement agreement.

How to structure payments to minimise tax

There are legitimate, HMRC-approved methods for structuring a settlement to reduce your overall tax burden. These should always be agreed with your employer and documented correctly in the settlement agreement.

Timing payments across tax years. If your settlement is agreed late in a tax year (e.g. March), it may be worth deferring the ex-gratia payment to the new tax year (April onwards) so it falls in a year when you have not yet used your personal allowance and lower rate bands. This can save thousands of pounds for higher-rate taxpayers. Confirm the employer is willing to agree a deferred payment date.

Pension contributions. Employer contributions directly into your pension scheme from a settlement payment are not subject to income tax or NI, provided they are within your annual allowance (currently £60,000 per year, though carry-forward of unused allowances from previous years may allow more). For higher earners, redirecting a portion of the settlement into pension can be highly tax-efficient. This requires the employer's agreement and must be structured as an employer contribution — not a payment to you that you then put into a pension.

Legal and professional fees. The contribution your employer pays toward your legal fees for advice on the settlement agreement is not taxable income to you. If your legal costs exceed the employer's contribution, the excess is not deductible against the settlement payment — but make sure the contribution is clearly identified in the agreement as a separate payment rather than part of the ex-gratia sum.

Correct categorisation of payments. Ensuring that payments genuinely qualifying for the £30,000 exemption are correctly identified — and that contractual sums (notice pay, holiday pay, bonus) are separately identified — is essential. A well-drafted settlement agreement with clear payment schedules helps both you and your employer comply with their payroll obligations correctly.
