I am employed (PAYE). I have never registered for Self Assessment as I have never needed to. I do not have a Unique Taxpayer Reference. I have Capital Gains Tax to pay on shares sold. As this is to be a one-off, I submitted my information via the Real Time Transaction service. This was on 1st November 2024. I have yet to receive a Payment Reference Number from HMRC. Payment is due by 31 January 2025. What do I do if I do not receive a PRN in time? From what I understand, if I go down the Self-Assessment route, I must submit and await a response from HMRC to obtain a UTR. I would rather not register for self-assessment as declaring income other than my PAYE will not happen in the future as my understanding is that once you register for Self-Assessment, you need to file annually, even if you've nothing to declare. Even if I did have to go down the Self-Assessment route, what if I did not receive my UTR in time to make payment for 31 January 2025?

Good afternoon, I am currently using the CGT calculator (non-property) on the tax.service.gov.uk site and have a query. Where it says: "In the 2023 to 2024 tax year, what was your income? Include your salary before tax", is this my gross salary or my salary less any salary sacrifices? Example: Gross annual salary of £50,000 Annual workplace pension salary sacrifice of 10% (£5,000) Annual car lease salary sacrifice of £5,000 Income (pre-tax): £40,000. Would my answer to the calculator question be £40,000 as that's my taxable income OR the £50,000 gross salary even though £10,000 isn't taxable? Thanks
