Capital gain tax

Hi, I have two questions on capital gain tax: 1) if I make gains and losses on my share investments but net-net is a loss, do I still need to file a self assessment (provided it is the only item to file, other than my salary which is tax-deducted)? 2) if my stock trading account is a joint account with my spouse, do we both need to file a self assessment or only one of us can do? Great if I can get more insight from you. Thank you!

Hi crowlkc,

Yes you would need to let HMRC know so that any losses still available could then be used at a later date.

Thank you.

Thanks, so if my stock trading account is a joint account with my spouse, do we both need to file a self assessment or only one of us can do? Thanks!

Hi

You both need to file separate tax returns, declaring your individual gains/losses and income.

Thank you
