I'm doing my tax return for 19-20.
I left a job in mid March 2020. The paperwork didn't get to payroll, they paid me in full at the end of March and issued a P60. I then got a "nil" P45 in April (for 20-21), and an invoice for the pay owed but with no tax-type details on it.
What do I put in my tax return? Have I got all the info I need? I can't help thinking that I should either have a replacement P60, or a P45 with negative pay, or the P45 I should have got all along in 19-20.
