Tax transactions mark a new era for tax law in Brazil. Tax authorities in various other countries already have mechanisms of a similar nature, which have long been a part of their taxpayers' lives. This mechanism, therefore, represents a step forward in the Brazilian tax authorities' relationship with taxpayers – one based on trust and credibility. This trust ensures a more harmonious relationship between the parties that is less likely to result in litigation. Meanwhile, the system gains credibility both in terms of the parties' interactions and in the desired outcome. In my opinion, tax transactions are an evolution that should be applicable to all taxpayers. There's no turning back now
