Cedar Trail's return claims a $50,000 benefit for a research deduction. The tax director says the position is “probably fine” and books the full amount. That sentence does not document either Topic 740 step.

Step 1: recognition on technical merits

Ask whether the position is more likely than not to be sustained upon examination, including applicable appeals or litigation, based on technical merits and under the required assumption that the taxing authority examines the position with full knowledge of relevant information.

This is a legal and tax-technical conclusion. The course case supplies a conclusion and supporting memo for accounting use. A learner evaluates whether the memo addresses the correct position, unit of account, authority, facts, reporting date, and examination assumption. The calculator accepts only the result; it cannot create the legal analysis.

If recognition fails, no benefit is recognized. Do not proceed to a probability average and do not recognize the full benefit with a valuation allowance.

Step 2: cumulative-probability measurement

For a position that passes recognition, order possible benefit amounts from largest to smallest and accumulate their settlement probabilities:

Benefit sustained Probability Cumulative probability
$50,000 20% 20%
$40,000 35% 55%
$20,000 30% 85%
$0 15% 100%

The recognized benefit is $40,000: the largest amount whose cumulative probability exceeds 50 percent. The $50,000 outcome alone reaches only 20 percent; adding the $40,000 outcome brings the cumulative probability to 55 percent, so $40,000 is the first benefit level to cross the threshold. It is not the $27,000 expected value and not automatically the single most likely outcome. The ending unrecognized tax benefit is $10,000.

Roll uncertainty through the provision

If the opening unrecognized benefit was $6,000, the $4,000 increase raises recognized current tax expense under the bounded fact pattern. Track interest and penalties under the entity's supplied accounting policy and disclose the policy as required. Settlements, statutes of limitation, changes in technical merits, and new information receive dated rows rather than retroactive edits to the original probability table.

Keep the balances distinct

An unrecognized tax benefit is not called a DTL merely because settlement may occur later. A valuation allowance does not repair a failed uncertain-position recognition conclusion. Presentation depends on what balance the uncertainty affects and the applicable guidance.

Test the position file

For each position, retain the unit of account, return benefit, technical-merits memo and owner, recognition result, ordered settlement outcomes, cumulative probability, recognized benefit, unrecognized benefit, interest and penalty policy, expected settlement or statute evidence, rollforward change, and rate- reconciliation effect.
