PAL in self assessment

How do I add a payment after leaving (bonus payed 2 months after leaving the company) in the Self Assessment form? This payment was not included in the P45 or P60, I just have a payslip. Should I add it as another employer even though I was not employed by them during the fiscal year? or as 'Other UK Income' / Employment lump sums, compensation and deductions and certain post-employment income (6th option in the online form). Thanks

Hi dolores_1980,
You can complete an employment page.
For the other question regarding post-employment income, please see here for guidance on if that section needs to be completed:
