Why it matters
The surprise is the problem.
I was unaware of the implications of wash loss sales so I just carried on trading the full year... rendering my total tax liability to be 4x higher than it should have been.
I’ve spent hours trying to understand this, but still struggling... 1099-B from broker shows... a loss of -$2200. Does this sound like wash sale territory?
I closed all my positions before year end and allowed 31 or more days to pass... despite this, my 1099 summary is showing disallowed wash sales.
February is late. The trades are done. The tax bill is real. Check supported activity before filing season.
