I receive a "consolidated" 1099-B from my broker. It has separate sections for ST gains/losses with Box A and Box B checked and LT gains/losses with Box D and Box E checked. Four separate sections.
What exactly is and is not reported to the IRS?
According to Form 8949 instructions, Box A and Box D are checked when the __basis__ [sic] is reported to the IRS by the broker.
I assume that means that the broker reports __all__ of the details of each Box A/D transaction to the IRS: proceeds and gains/losses as well as the basis. Right?
The more important question is....
And according to Form 8949 instructions, Box B and Box E are checked when the __basis__ [sic] is not reported to the IRS.
Does that mean that the broker reports __none__ of the details of Box B/E transactions to the IRS: __not__ proceeds and gains/losses as well as __not__ basis?
