Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter A— Determination of Tax Liability › Part VI— ALTERNATIVE MINIMUM TAX › § 56A
Corporations must start with the net profit or loss shown on their applicable financial statement for the year, then change that number in certain ways to get their adjusted financial statement income for tax purposes. "Adjusted financial statement income" means that book profit or loss after the rule changes. "Applicable financial statement" means the company’s official financial report for the year, as defined by other tax rules or IRS guidance. Adjustments are made when the financial report covers a different period than the tax year; when results are for a group of companies; when the company owns or is owned by others (including partnerships, subsidiaries, controlled foreign corporations, or disregarded entities); and when special items appear on the books but are treated differently for tax. The rules ignore federal income taxes and generally ignore foreign income or war-profits taxes taken on the books (with some exceptions). Cooperatives, Alaska Native claims items, and some tax credits or payments have special timing rules. Mortgage-servicing income cannot be counted earlier than it is taxed, and the IRS will issue rules to stop abusive arrangements and to align book and tax treatment of benefit plans, depreciation, depletion, amortization (including special rules for certain wireless spectrum bought after December 31, 2007), corporate reorganizations, liquidations, and partnership contributions or distributions. After making those adjustments, the company must lower its adjusted financial statement income by the smaller of the total financial-statement net operating loss carryovers it has or 80 percent of the adjusted income before this loss deduction. A financial-statement net operating loss is a book net loss from a year ending after December 31, 2019, and any unused portion carries forward. The Treasury/IRS will provide regulations and guidance to explain and apply these rules.
