Narrative Opinion Summary
The case involves an appeal by the Illinois Department of Revenue against a Cook County circuit court's decision favoring Miami Corporation, a Delaware entity with significant oil and gas interests. The core issue revolves around the appropriate method for apportioning income attributable to Illinois for tax purposes, specifically whether Miami Corporation could deviate from Illinois's statutory three-factor formula and utilize separate accounting for its Louisiana operations. Originally, the Department applied the three-factor formula, which Miami Corporation contended significantly distorted its income allocation, leading to excessive tax liabilities for the years 1978 to 1982. The trial court sided with Miami Corporation, permitting the use of separate accounting, a decision affirmed by the appellate court. The court concluded that the statutory formula did not accurately reflect Miami Corporation's business activities in Illinois, particularly given its unitary nature and the substantial income derived from its Louisiana oil and gas assets. The case highlights the constitutional requirement for accurate state taxation of corporate income and the permissible use of alternative apportionment methods under section 304(f) of the Illinois Income Tax Act when statutory formulas result in significant distortions. Ultimately, the appellate court upheld the trial court's ruling, granting the requested tax refunds to Miami Corporation.
