can I submit self assessment for the capital loss I made in 2018

Dear HMRC, I have one UK investment account in 2018. I made some capital loss in this account. It is the end of 2022 now. Can I still register this capital loss via HMRC? How can I do that?

Hi
Capital losses must be notified within 4 years of the end of the tax year in which they arise so if the loss you refer to is for year end 05/04/2018, it is now too late to report this and use it.
Capital Gains Tax: what you pay it on, rates and allowances
Thankyou.
Regards.

this happens in the later 2018. Is there a penalty if I submit this capital loss in the self assessment for 2018-2019 year now?

Hi nick zg99,

You do not need to submit a tax return to declare it.You can do this by letter.

As it is for the year end 5/4/19, you will need to ensure the information is submitted prior to 05/04/23.

You should give the details of the company involved, the date and amount of original investment and the reason for the loss

Thank you. 


 

Can you please give me the address I should send the letter to?

Hi,

The address is:

HMRC
PAYE & Self Assessment

Thank you.
