I'm a rebel, I don't attach anything.  As long as the gross proceeds match, there wont be any CP2000, and nobody is going to look at those attachments.

I did attach an 8949 from Cointracker for crypto currency transactions, since it didn't come from a brokerage and I summarized on Sch D.

F I N E.....I'll come visit you in jail (where Timmy will be too) & bring a cake with a file in it.  

I do attach, but I agree with you.  NO ONE is looking at them; years ago before you could scan/attach I would say I was gonna' mail & more than one got *forgotten* (I'd find them in the file the following year...).  Never heard a peep from the IRS.

I forgot some of those, too. Nowadays you don't have to attach the covered ones.

I used to send them in by mail back in the days when the brokerage reports rarely included the basis and people were bringing in their own hand written worksheets showing their buys.  Once the brokerages started including basis, I stopped mailing them and I've never attached one, except for that crypto one.

I always felt bad for the person that had to open all those envelopes and scan them in for nobody to ever look at them again.

Thanks for the great advice! This saves me a ton of time.
