I have completed my tax return online via Government Gateway. The tax calculation shows 'Interest from UK banks, building societies and securities etc: £13,912.00' I'm not clear how this is calculated. I would have expected the total to be based on Box 1 and Box 2 (taxed and untaxed interest respectively) but there seems to be something else going on. My Box 1 and Box 2 figures are as follows: Taxed UK interest (box 1): £8,230.50 Untaxed UK interest etc (box 2): £3,625.95 I am not clear where the figure of £13,912.00 comes from, and cannot see a breakdown of it. I will be paying tax at 40% on this interest, so would expect to be paying 40% on the untaxed interest, and a further 20% on the taxed interest, after the £500 allowance. I have got some dividend income but would not expect this to affect the interest total. I have not got any gilts.

I have a capital loss from publicly-traded shares from a previous year. I understand that I can carry this loss forward and subsequently offset it against a gain in future. I get the impression that I am supposed to enter it on my tax return but cannot see where. I presume it would be box 47 ('losses available to be brought forward') but cannot find this box or the equivalent in the Capital Gains section when completing Self Assessment online. Can anyone advise?
