Let’s be direct: AI is one of the most powerful capacity tools tax professionals have seen in decades. Used correctly, it buys you time you can reinvest into high-value advisory: planning, structuring, audits, negotiations, strategy, client education, and relationship building. But here’s the catch that you as an elite tax practitioner already understand: aggressive planning requires rigorous defensibility. If you’re going to use AI to accelerate complex planning work, your defense file must be stronger, not weaker. This playbook gives you that: a practical framework that keeps you safe while you scale.

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.
