Various rulings and tax agency actions in 2023 were arguably “unusual” and “surprising.” Most of these items were not the key holding of court decisions or IRS news releases or guidance. They were more subtle or buried. This article uncovers a variety of these oddities and posits what we might learn from them.

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.
