I do keep my own, but I only recently started checking what I have against what Ebay has at the end of each month.

Prior to that I assumed Ebay would give sellers a full summary of each financial year, because as a business, Ebay is required in virtually every western country to keep records of their financial activities, which clearly they do. So the ability to provide a yearly summary to seller is already within the system they have, they just dont bother to do it (it would be automated, its not like theyd have to DO much at all).

I hope this is one thing that changes soon. There's no reason why it shouldnt be provided to sellers ongoing, and every reason why it should be. It would be cheaper for Ebay to have it incorporated into their current system, which has the ability to do it, rather than pay out for time and man power for each individual request when a seller is audited or their harddrive dies (unless they charge for that too!).
