Correct way to amend tax return as a result of not correctly reporting gains on sale of private stock based on Installment method?
After much research, the answer is "a": recompute the tax return using the installment sales method because (1) the escrow payment was subject to "substantial restrictions" by virtue of the escrow being structured to pay buyer's indemnification claims and (2) the taxpayer did not correctly elect out of the installment method by reporting the entire gain including the escrow payments on the return in the year of the transaction.
