How to Declare a Settlement Agreement on Your UK Tax Return (SA100 / SA102)
If your employment settlement agreement includes compensation exceeding the £30,000 threshold under Section 403 of ITEPA 2003, or if you already file a UK Self Assessment tax return, you must declare your settlement correctly. This guide provides a box-by-box breakdown of forms SA100 and SA102, and explains how to handle the employer tax indemnity clause.
Where do I declare settlement agreement payments on my tax return?
Termination payments are declared on supplementary page SA102 (Employment) or the "Additional Information" page online. The tax-free element up to £30,000 goes into Box 5. The taxable excess exceeding £30,000 goes into Box 9, and any PAYE tax deducted by your employer is recorded in Box 10.
1. Box-by-Box SA100 / SA102 Breakdown
When filing your Self Assessment return online or on paper, termination payments must not be lumped into ordinary salary. Entering termination awards into Box 1 will result in HMRC calculating employee National Insurance contributions, which do not apply to genuine compensation for loss of office.
Box 5: Lump sums or other benefits up to £30,000
Enter the genuine compensation amount that qualifies for the £30,000 exemption under Section 403 of ITEPA 2003. This includes statutory redundancy pay, enhanced severance, and non-contractual ex-gratia sums. If your total compensation was £25,000, enter £25,000 here.
Box 9: Compensation and lump sums exceeding £30,000
If your total qualifying compensation was £50,000, the first £30,000 is exempt (Box 5) and the remaining £20,000 is entered in Box 9. This amount is subject to income tax at your marginal rate (20%, 40%, or 45%) but remains free of employee National Insurance.
Box 10: Tax taken off box 9
Record the PAYE tax already deducted by your employer on the payment entered in Box 9. Employers typically apply an emergency tax code or 0T code. Recording this prevents double taxation.
2. The Employer Tax Indemnity Clause Explained
Virtually all UK settlement agreements contain a tax indemnity clause. This clause requires you to reimburse your employer if HMRC concludes that additional tax or National Insurance is due on your severance package.
Employers insert this clause because PAYE regulations place primary liability on the employer for under-deducted tax. However, unrepresented employees often accept aggressive indemnity clauses that leave them exposed to unfair liabilities.
Essential Solicitor Protective Amendments:
- Exclude Employer NICs: Confirm you only indemnify standard income tax, never employer Class 1A NICs (15.0%).
- Exclude Employer Penalties: Ensure you are not liable for interest or penalties caused by your employer's payroll delay.
- Advance Written Notice: Require the employer to give you at least 21 days notice before responding or settling with HMRC.

Frequently Asked Questions: Tax Return Reporting
Do I need to file a Self Assessment tax return if my settlement agreement was under £30,000?
If your total termination package was entirely below the £30,000 threshold under Section 403 of ITEPA 2003, and all notice pay was taxed via PAYE with no other untaxed income, you generally do not need to register for Self Assessment solely because of the settlement. However, if you are already registered for Self Assessment, HMRC requires you to report termination awards on your SA102 return.
Which boxes on the SA102 Self Assessment form do I use for a settlement agreement?
On supplementary page SA102 (or the "Additional information" section Ai 2 online), enter qualifying non-taxable termination payments up to £30,000 in Box 5. Enter any taxable compensation exceeding £30,000 in Box 9, and record the PAYE tax already deducted by your employer in Box 10.
Why does my employer insist on a tax indemnity clause in the settlement agreement?
Under UK tax rules, the employer is legally responsible for operating PAYE correctly. If HMRC subsequently challenges the tax-free status of any payment, HMRC can issue an assessment against the employer. The tax indemnity clause enables the employer to reclaim any unpaid income tax and interest directly from you.
How should my solicitor amend the employer tax indemnity clause?
Your solicitor should ensure the indemnity covers only income tax (not employer Class 1A National Insurance contributions), excludes penalties resulting from employer payroll delays, requires the employer to give you written notice before settling with HMRC, and gives you the right to dispute unreasonable HMRC assessments.
Does an employer contribution to my legal fees count towards the £30,000 exemption limit?
No. Under HMRC Extra-Statutory Concession A81 and Section 413A of ITEPA 2003, payments made directly by an employer to your solicitor for independent legal advice under Section 203(3) ERA 1996 upon agreement completion are completely tax-exempt and do not consume any part of your £30,000 threshold.
