2019 Loss Limitation School - 461(l) Excess Business Losses, NOLs, 163(j), Basis, At-Risk and Passive Activity Losses

Do you desire to not be tripped up and held back by the plethora of loss limitation rules that threaten deductibility of business losses? The new menacing §461(l) excess loss rules are poorly drafted and have no meaningful interpretation. The NOL rules have been turned by TCJA upside down on their ear. §163(j) has been added to trip up business interest expense.


How do these new loss limitation rules interact with the age old basis, at-risk and passive activity loss rules? This course lays it all down for you and gets you through the woods as unscathed as possible.
