On July 16, the Brazilian Supreme Federal Court (STF) reinstated the higher IOF (Tax on Financial Operations) rates established by presidential decree, restoring taxation on financial transactions retroactively to June 27, 2025, the date on which the decree had been suspended by Congress.
With the single‑judge decision issued by Justice Alexandre de Moraes (07/16), the following rules are once again in effect:
However, the government’s attempt to tax the risco sacado (a type of supply‑chain financing) was rejected. The Justice held that this operation does not constitute a credit transaction and, therefore, cannot be subject to IOF, noting that extending the tax to this structure would exceed the Executive Branch’s constitutional authority.
The decision has raised concerns in the financial market, including fears of capital‑control measures and a potential uptick in offshore investments as a protective strategy. The reinstated, higher IOF rates — now valid retroactively — may significantly affect companies and investors who did not pay the tax during the suspension period.
