The laws of tax planning that I developed over my writing career that will be expounded in the upcoming Reilly’s Laws of Tax Planning, published by Think Outside the Tax Box, lean a little on the conservative side, as tax planners use the term – conservative versus aggressive, not conservative versus liberal. This results, in large part, from their primary source being court decisions.
The 18th law stands out from the others in this regard. “Honest objective trumps realistic expectation” encourages practitioners to be somewhat more aggressive in claiming losses from activities that seem a little dubious . I still hold that view, even though there have been no encouraging developments in 2023. Here is a roundup on the action last year through December 2, 2023.

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.
