The Brazilian Bar Association (OAB) in Rio de Janeiro has recently secured a favorable ruling to temporarily suspend a proposed tax increase on law firms that operate under the presumed profit tax regime. This ruling was issued by Federal Judge Débora Maliki from the 6th Federal Court in São João de Meriti, Rio de Janeiro, and arises from concerns regarding the legal nature of the increased taxation. The contested tax increase, set at 10%, forms part of broader fiscal adjustments stipulated by Complementary Law No. 224/2025, which aimed to cut down various tax benefits.

The OAB-RJ's primary argument against the tax increase is that the presumed profit regime should not be categorized as a fiscal benefit but rather as a legitimate method for calculating taxes. This distinction is crucial for determining the rights of law firms to continue paying taxes at previous rates until a final decision on the legality of the tax increase is reached. Judge Maliki's ruling underscores that lawmakers cannot arbitrarily redefine the legal category of a tax scheme in order to justify increased revenue generation under the guise of fiscal benefit reductions.

Furthermore, Judge Maliki noted that the changes imposed by Law No. 224/2025 potentially violate constitutional limits by misclassifying the presumed profit regime as a fiscal benefit. This legal challenge highlights the ongoing debates surrounding tax policies in Brazil, particularly how they affect legal professionals and small business owners. The implications of this suspension could extend beyond law firms, potentially influencing how other sectors respond to similar tax adjustments in the future, as it sets a precedent concerning the taxation of businesses operating under specific regimes.
