Wyden Calls Accounting Giants to Reveal Malta Tax ‘Secret Sauce’

U.S. Senator Ron Wyden, the ranking Democrat on the Senate Finance Committee, has asked the four biggest accounting firms to describe the Malta‑focused tax advice they provide to corporate clients. Wyden says the firms’ work may be enabling corporations to shift billions of dollars offshore, and he wants a clear picture of the mechanics behind those strategies.

The request was made during a Senate hearing, and the firms have indicated they will cooperate with the committee’s investigation.

Wyden’s move underscores the Senate’s growing focus on offshore tax avoidance and signals that the era of opaque Malta‑based structures may be coming to an end. The investigation remains ongoing, and further disclosures are expected as the committee presses for transparency.
