Plain-English summary

Chief Counsel Advice discusses why taxpayers referred to as IC taxpayers cannot amend their returns after being selected for audit under the rationale described. The advice says that some IC taxpayers are not selected for audit in some years, which could allow them to take tax positions beyond reasonable bounds in the hope of avoiding an audit. It contrasts this with CIC taxpayers and compares post-selection amendments under Rev. Proc. 94-69 to withdrawing an audit-risk bet after the outcome is known.

I don't know that that was the only reason, but I think it played into the rationale.

Rationale:
Since IC taxpayers are not selected for audit in some years, they can play "audit roulette", i.e. take tax positions beyond reasonable bonds on the chance that they will not be selected for audit. (CIC taxpayers can not play audit roulette). For this reason, IC taxpayers can not amend returns once selected for audit. Allowing IC taxpayers to amend their returns after being selected for audit, pursuant to Rev. Proc. 94-69, is the equivalent of permitting audit roulette players to withdraw their bets - in the form of penalty - after the roulette ball falls into the audit pocket.
