and makes adjustments
Tax Balance Sheets--the missing
statements
Balance Sheets vs. Tax Returns
Source of Confusion
GAAP measures A, L, and E
Tax takes (unimportant) Changes to get
Taxable Income
Example: Accounting for Income Taxes
GAAP trying to measure Deferred Tax ASSETS
and LIABILITIES

a failure to appreciate the role of
accounting
