We all know how messy tax returns can get when couples who used to file jointly divorce and there are children (and tax credits) involved. It’s often difficult to explain the rules surrounding Head of Household filing status and the various tax credits available to parent-clients who have separated or divorced. But what happens when the clients misunderstand and decide to fight about it in family or divorce court? The following case study says “nothing good” can be a horrifying and frustrating answer to this question.

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.
