CGT on LLC Dissolution

My husband and I live in the UK and hold rental properties within an LLC in the US. The LLC is in the process of being dissolved. My understanding is that the resulting distribution will be a capital gain rather than a dividend. On which form is this CGT reported, and can the base cost be deducted? Thank you.

Hi,

You can see guidance here:

Capital Gains Tax: what you pay it on, rates and allowances

Thank you.
