“Audit disputes regarding positive and negative evidence for tax asset realizability”
Manual Data Flow Trap
1Manual Export
Attribute Export
Deferred tax balances dumped from the provision model into a working file.
2Stale Evidence
Memo Paste
Positive and negative evidence reused from prior-year Word files, not the current schedules.
3After Fieldwork
Fieldwork Adjustment
Auditors re-perform the conclusion and change the allowance after close.
Root Operational Bottleneck
Deferred tax assets are judged realizable in a quarterly provision workbook whose positive and negative evidence is pasted from prior-year memos and forecasts that are not linked to the attribute schedules.
Control Hazard & Audit Exposure
Auditors dispute the valuation allowance because the working papers cannot show which facts supported the conclusion in the period, so the allowance is adjusted after fieldwork.
Manifests in: Tax provision model and valuation allowance working papers
Deterministic Replacement (After)Golden Door Standard
Target Software Architecture
ASC 740 Tax Model & Scenario Evidence Archival Engine
Deterministic Pipeline Execution
1Linked
Attribute Ledger
Deferred tax balances are stored with their originating book-tax differences.
2Contemporaneous
Evidence Records
Each fact is dated, classified positive or negative, and attached to the DTA line.
3Locked
Versioned Conclusion
The allowance posts only from the evidence set whose conclusion matches the entry.
Deterministic Software Pattern
ASC 740 tax-attribute engine that stores each piece of positive and negative evidence against the DTA schedule and versions the allowance conclusion per period.
Continuous Assertion Rule
Realizability assertion: the valuation allowance cannot post unless every DTA balance cites contemporaneous evidence records whose conclusion matches the booked allowance.
