FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes"


Notice: Historical Content

This is an archival or historical document and may not reflect current law, policies or procedures.

In June, 2006 the Financial Accounting Standards Board issued Interpretation 48 of Financial Accounting Standard 109. This interpretation, known as “FIN 48”, is intended to eliminate inconsistency in accounting for uncertain tax positions in financial statements certified in accordance with U.S. GAAP. FIN 48 mandates new rules for recognition, de-recognition, measurement, and disclosure of all tax positions.

FIN 48 Policy and Field Guidance

IRS has determined that documents produced by a taxpayer and/or its auditors to substantiate the taxpayer’s uncertain tax positions in compliance with FIN 48 are included within the Service’s interpretation of Tax Accrual Workpapers and are therefore subject to the applicable policy of restraint.
