Taxation of savings interest

If interest is added to a multi-year fixed term savings account annualy, but cannot be withdrawn until the account matures, does the tax liability for the interest occur each year it is paid (even though it stays inaccessible in the account), or does the whole tax liability occur in the tax year when the account matures? Thank you.

Hi

No.  If you cannot access the account or the interest until the account matures, the full amount of interest is then only taxable in the tax year the account matures.

Thank you
