Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter A— Determination of Tax Liability › Part VII— BASE EROSION AND ANTI-ABUSE TAX › § 59A
Large U.S. corporations that meet size and payment rules must pay an extra tax for a year if they make enough deductible payments to related foreign parties. The extra tax is the amount, if any, by which 10.5% (5% for years starting in 2018) of a company’s "modified taxable income" is more than its regular tax after most tax credits. If the company is in a group that includes a bank or a registered securities dealer, the 10.5% rate is increased by one percentage point. Some credits can lower the regular tax, but the research credit is handled separately and certain housing, energy, and investment credits are limited so they only reduce the extra tax up to 80% in some cases. Modified taxable income: taxable income recalculated without deductions tied to those foreign-related payments and without the base-erosion part of any net operating loss. Base erosion payment: amounts a company pays to related foreign persons that are deductible, such as payments for services, interest, royalties, buying depreciable property, reinsurance, or items that reduce gross receipts because of certain foreign related corporations. Applicable taxpayer: a C corporation (not a RIC, REIT, or S corporation) with average annual gross receipts of at least $500,000,000 over the last three years and a base-erosion percentage of at least 3% (2% for the bank/dealer groups). Related party: large owners (25% or more) and other closely connected persons or entities under tax rules. Qualified derivative payment: certain marked-to-market derivative payments that meet strict reporting rules and are treated as ordinary. The Treasury can write rules to prevent avoidance or tricks to escape this tax.
