The Cohan rule is named for George M. Cohan. George Michael Cohan (1878 – 1942) was a theatrical producer. In the decade before World War I, he was called the “man who owned Broadway” and is considered the father of American musical comedy. In 1940 he was awarded the Congressional Gold Medal for his contribution to morale during World War I with his songs “You’re a Grand Old Flag” and “Over There,” the first time the medal was awarded to someone in an artistic field. But his most enduring legacy may be the tax rule that shared its name.

State Tax Planning with the “80/20 Company” Exclusion
Many multinational groups find that foreign-source dividends and other income earned by domestic affiliates are fully or partially subject to state income taxation, even where the federal system provides an exemption. This state-level “leakage” can be material – particularly in high-tax jurisdictions – and is often overlooked because the income appears sheltered at the federal level. For groups with predominantly foreign operations, a starting structure or a restructuring that causes one or more domestic affiliates to qualify as an “80/20 company” can substantially reduce or eliminate state taxation on that income.
