"Prove it" dumb ass.
From Forbes 2020
“Presidents aren't required to release their returns to anyone — and the IRS is prohibited from even discussing the existence of any individual president’s return. But to say that presidential tax secrecy is legal isn’t the same thing as saying it’s right.
American presidents, when acting in their private capacity as American taxpayers, are basically above the law — at least during their time in office. And because their taxpaying is the focus of broad and consistent public attention, any problem with their behavior poses an existential threat to the popular consent that makes the tax system function.
The United States needs a law mandating presidential tax disclosure — even if it means giving Trump a pass and imposing it only on future chief executives.
Roles in Tension
Presidents have a dual relationship with the tax system. On one hand, they serve as the nation’s tax collector in chief, supervising the agencies charged with enforcing the tax law. At the same time, however, presidents are themselves taxpayers, subject to the same legal responsibilities as anyone else. In practical terms, this arrangement means that presidents must police their own tax behavior.
In theory, the IRS is keeping tabs on presidents and their taxes. Since 1977, the agency’s internal guidelines have required an annual, automatic audit of returns filed by sitting presidents and vice presidents.”
