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.

Charitable Impacts of the One Big Beautiful Bill Act
For charitable-minded taxpayers, several provisions in the One Big Beautiful Bill Act (OB3 Act) will impact the tax reduction associated with their charitable giving starting next year in 2026. In one case, the change increases the deductible amount, but all other changes surprisingly reduce the value of charitable contribution deductions. This article will review how the OB3 Act changed the charitable contribution deduction landscape and strategies for tax year 2025 and beyond to maximize the tax reduction value from charitable contributions.
