I've done a few returns now, who have only one or two broker packets. I am kinda getting to like it, especially for the "reported to IRS/covered" sales. The brokerages are providing a summary that's now very easy to enter into 1099-B link. In prior years I used to send the details by mail with Form 8453 which was a pain. So this is a huge improvement! Entering the trades that are not reported / uncovered / to the IRS is less fun. Over time, these latter should diminish in number. I still don't know if the 1099-B's will be easy if a client has several accounts with several brokerages. But I have only a few clients who like to diversity that way.
