Pls give advices on how to report interest income

Dear HMRC, I am seeking clarification on how to report interest income for the following scenarios: Case 1: Interest Credited to a Joint Account: I opened a fixed deposit savings account in my name (a single account). Upon maturity, the bank transferred the total amount (principal + interest) into a joint account shared by my spouse and me. When filing a tax return, should I report 100% of the interest earnings, or should the amount be split equally (50% each) between the two account holders? Case 2: Interest Credited Monthly on a Fixed Deposit: I have a fixed deposit account with a 12-month term. The bank credits interest into my account on a monthly basis, even though the deposit has not yet reached maturity (I was told by the bank I am allowed to take the money away before maturity). In this case, how should I report the interest income? Should I declare the interest received monthly in the corresponding tax year, or wait until the deposit matures to report the total interest? Your guidance on these matters would be greatly appreciated to ensure compliance with HMRC regulations. Thanks

Hi
1) On your return, declare the amount you received personally - in this case, 50% of the total interest paid out by your bank. 2) You do not need to declare this interest until maturity, when the interest is credited to your account and made available to you to use.
