In dissolving the LLC/ multi-member partnership, there are several things to consider. First is the final K-1 which shows the separately stated items from the partnership that must be reported.
Then there is the disposition of your partnership interest. That is considered the disposition of a capital asset. After considering the final K-1 adjustments, you have to recompute your the basis in your partnership interest.
You then compare the basis of the partnership interest to what you receive. The difference is generally a capital gain or loss. However, certain things such as unrealized receivables/inventory, etc., may result in ordinary gain. Here are some links to help.
