As a landlord I've been required to fill out self-assessment. Today I started to fill out the self-assessment but saw a message (sent August 2022) in my account that said: Stopping Self Assessment. You don't have to send a tax return after year ended 5 April 2022 unless your financial circumstances change or HM Revenue and Customs tells you to. I have no idea why self assessment has been stopped. Any ideas, and what should I do?
