| Well, that is what most CPA's are doing these days, they are simply reporting Netting out both the Sales and Purchases for all the Short Term purchase and using the date as "Various" and doing the same for the Long term transactions as well.
This is clearly meant to avoid to individually stating each and every transaction, due to the fact that not only is this very tedious but it is costly for the client. As long as you clearly indicate the Wash Sale nature of the transaction and show that the losses are considered disallowed due to the Wash Sale Rules then I think you should be fine! |
