ASC 740-10 Accounting for Uncertainty in Income Taxes

ASC 740-10 Accounting for Uncertainty in Income Taxes

ASC 740 (formerly known as FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes or “FIN 48”) establishes a “more-likely-than-not” threshold for the reporting of uncertain tax positions on financial statements. This standard requires new disclosures in annual financial statements, including a reconciliation of total unrecognized tax benefits, classification of income tax-related interest and penalties, years which remain open to examination and unrecognized tax benefits that are expected to significantly change within 12 months of the reporting period.

ASC 740 brings significant changes to tax compliance and financial reporting and requires the design of a comprehensive plan for evaluating and tracking uncertain tax positions. For many companies, development and implementation of this type of plan and associated processes and procedures can be overwhelming, particularly for those subject to multiple tax jurisdictions.
