Informing HMRC about no self-emplyed work in tax year

All my earnings have been taxed at source this financial year, I haven't done any self-employed work. I don't need to submit a self-assessment, but believe I need to inform HMRC about the situation. How do I do that?

Hi Nicolajw,

You can do this by contacting our Self Assessment helpline.

Self Assessment: general enquiries

Thank you.
