P50Z - mistake in completion?

I emptied a pension pot and as advised by the pensions company, I filled in a P50Z as I have no PAYE income as finished my job in September 2023 and just have a small amount of self-employed income. There was a question about whether I had earned any self employed income since stopping work so I included the amount earned since September 2023 - but does this just mean this tax year? If so I have completed this incorrectly. I'm also unclear about the do not submit within 4 weeks of stopping work guidance - I thought that meant finishing my job but does it mean since getting the pension? I do I communicate with HMRC about the form?

Hi Jay Sear,
You would include the self employment income earned since you left your PAYE employment in September 2023.
Do not submit the form until 4 weeks have passed since leaving your employment or you've taken the pension payment - whichever is more recent. To discuss the form further, contact us by webchat or phone here:
