I just submitted sa1 form in 6 sep 2023, but no any reply about the UTR yet. There is also no record by checking the form submitted status in HMRC app. Second question , my wife is not self employed, but if she submitted the CWF1. The UTR she still can use to submit tax return? Or she need to submit SA1 again to get another UTR? Third question, if my father got oversea bank saving interest and uk bank saving interest, but the total is within his personal allowance. He still need to register self assessment? Thank you. I am quite annoying on the tax issue that my whole family settle in UK just a short term period.
