Disposal of an asset

Tax Questions
#1

I have filled in my self assessment, it is the first time I have needed to fill in the Capital gains section.

This is what is written,

“you must provide a computation for each disposal of an asset which is not exempt from Capital Gains Tax. If you do not attach a computation you must provide the information in the any other information section”

I think the computation sheet they provide is for if you have up to 20 disposals, I have 3175 disposals.

In the capital gains section of the self assessment form there is a place to upload PDF files. What I have done is upload 128 pages of Capital Gains Transactions from the 169 page Koinly Complete Tax Report.
I also uploaded the 2 page Koinly HMRC Summary Report.

Do you think that will be sufficient?

I know you are not tax advisors or allowed to give tax advice. I am asking your opinion about what I have uploaded and if you think I should upload any other files.

Hi @lykoin

You are right. While we cannot give tax advice, we can explain how Koinly reports are generally used for UK tax filings.

From what you described, you have done the right thing:

:white_check_mark: You uploaded the Capital Gains Transactions section (with all 3175 disposals).

:white_check_mark: You also included the HMRC Summary Report, which is specifically designed for UK tax returns.

These two documents together typically meet HMRC’s requirements, especially if you’re using software to generate your computations.

If you want to be extra cautious, I suggest you consult a crypto-aware tax accountant.
