Uncertain tax position

Working definition

A position taken or expected to be taken in a tax return whose financial-statement benefit depends on separate recognition and measurement under Topic 740.

An uncertain tax position is a return position whose financial-statement benefit requires separate recognition and measurement. It is not a deferred-tax-asset realization problem. Keep the technical-merits conclusion, benefit measurement, interest, penalties, settlements, statutes, and presentation in their own schedule.

Separate the two gates

ASC 740-10-25-5 requires a more-likely-than-not recognition criterion before and apart from measurement. The measured benefit follows only for a recognized position.

Suppose a return claims a $60,000 credit. A supplied technical memo concludes that recognition passes, and supported settlement outcomes measure a $45,000 benefit. The remaining $15,000 is unrecognized. A valuation allowance cannot be used to reach the same net result because it addresses realization of recognized deferred tax assets. This page does not establish the unit of account, technical merits, probabilities, interest policy, or legal conclusion.

A closing control ties the recognized and unrecognized portions back to the return benefit without hiding interest or penalties in either amount.
