Hi Ashly,
If you received P45s for both your NHS and NHSP employments, then use the P45 for the employment that you left most recently when completing your P85.
If you complete a Self Assessment return to declare your NHSP income, then you do not have to complete a P85 - send us a paper 2024/25 tax return, along with SA109 Residence pages, after the 6th of April 2025.
Tax if you leave the UK to live abroad.
Thank you.
