The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, doesn’t reinvent the tax code it refines it. Much like its predecessor, the Tax Cuts and Jobs Act (TCJA), it keeps many familiar provisions in play: lower rates, expanded SALT flexibility, and broader deductions. But here’s the real story: While most tax pros are busy memorizing what stayed the same, the planners who will win 2025 are the ones spotting what just became possible. OBBBA quietly opens a handful of powerful new planning windows — each one capable of delivering real, measurable savings for the right client. The key is knowing which changes are worth your time… and which are just political garnish. Below, we’ve curated the most strategic, high-impact moves to make before year-end 2025, the ones that separate the advisors who explain the law from those who leverage it. Most tax pros will stop at what changed. The smart ones will keep reading to learn how to use it.

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.
