Back of the envelope calculations indicate significant revenue can be raised if California conforms to GILTI.
The California Legislature is considering a bill (AB 71) that would subject 50% of a category of income derived from federal tax law, known as Global Intangible Low-Taxed Income (GILTI), to California’s corporate income tax. In short, GILTI represents an attempt by the federal government to estimate, by formula, how much income — really earned in the US — has been shifted to low-tax jurisdictions to avoid US tax.
