It's incredibly frustrating to keep receiving tax penalty messages for the self-assessment year 2023-24. I started working in the UK on March 6, 2023, and worked only 26 days during the 2022-23 financial year. According to the HMRC site I used (https://www.gov.uk/check-if-you-need-tax-return), I shouldn’t need to submit a tax return. Calling a HMRC has too much waiting to resolve the issue.
