This bill primarily targets large multinational corporations rather than small businesses. However, small business owners could indirectly benefit if corporate inversions are curbed, since the resulting tax revenue could reduce pressure to raise taxes elsewhere, and a more level playing field means large competitors can't gain unfair tax advantages by relocating on paper to foreign countries.

Introduced in Senate
The bill was officially filed and given a number. It now enters the legislative queue.
Senate Democrats reintroduced the Stop Corporate Inversions Act, a measure aimed at preventing U.S. companies from shifting their tax domicile abroad. The bill would treat merged firms as domestic if original owners retain more than 50% control of the new entity.
S.3847 (Stop Corporate Inversions Act of 2026) was flagged as potentially relevant to multinationals including Amgen; the bill would tighten rules around inversion tax treatment — a longer-term policy item to monitor but not an immediate earnings driver.

The Stop Corporate Inversions Act of 2026 would treat a combined foreign corporation as a domestic corporation if the shareholders of the former U.S. corporation own more than 50 percent of the new entity, or if the group is managed and controlled in the United States.
