In some years, an extra line will show up at the bottom of the Allocation report, stating that one or more members must also claim some amount on their personal K-1 forms.
The reminder there only shows up if the member's basis went below zero during the year. This is normally only possible with a significantly large partial withdrawal.
Any negative cost basis figure at the end of the year is brought to zero when the allocation is done, so the note at the bottom of the allocation is more of a *Don't forget* reminder that the member's basis went negative during the year, than a listing for all withdrawals.
Members should be given a copy of their withdrawal report if they took any withdrawal during the year, but if the line does not appear, it only means that the member's cost basis did not become negative as a result of their withdrawal(s) during the year.
