Do I need to file a self-assessment?

I used this survey link (https://www.gov.uk/check-if-you-need-tax-return) on the government's website to see if I needed to do a self-assessment for filing tax return. The answer given to me was No - I do not need to send a self-assessment tax return. Basically, I have done my calculation when I answered the questions in the above link: 1) My income was below £50,000 for Tax Year 2022/2023 2) For Question 7 re Capital Gain Tax, I also answered No because I have not sold any personal assets at all, let alone assets valued over £6,000 and I have not sold/given away shares of holiday home. - I have however sold my sole and main residence in November 2022 but since this was not my "holiday home" and since it was my sole and main residence since 2022/2023, then I am exempt from capital gain tax. My Questions: #1 : Is it ok for me to follow the survey result above and not file a self-assessment tax return? #2: I did the above survey (this is the link: https://www.gov.uk/check-if-you-need-tax-return) AFTER I have registered myself with HMRC for a self-assessment. I have filled in the form and am waiting for my Unique Taxpayer Reference Number. - Is it ok to register myself with HMRC for self-assessment but do not file the self-assessment return?

Hi

Based on the information you have provided (after using our Self Assessment Criteria tool) you do not have to either
(a) register for Self Assessment or
(b) complete a 2022/23 Self Assessment tax return.

Thank you

My apologies, there is a typo in 2) above...I meant to say, "since it was my sole and main residence since 2002/2003, then I am exempt from capital gain tax". And I have met all the conditions for the full Private Residence Relief as stated here: https://www.gov.uk/government/publications/private-residence-relief-hs283-self-assessment-helpsheet/hs283-private-residence-relief-2023 May I confirm that your answers above - that I do not need to register for self-assessment nor complete a 2022/2023 self-assessment tax return still hold?

Hi

Yes, based on the information you have provided, you are not required to register for Self Assessment.

Thank you
