The consultants who lead every engagement.
TaxUp is a boutique Brazilian tax consultancy. Every engagement is led personally by a senior consultant — from the first diagnostic to oral arguments at CARF and the higher courts. These are the people who do the work.
A consultant-led firm
TaxUp is structured as a boutique by deliberate decision, not as a marketing label. There are no layered associates, no rotating juniors between meetings, and no work offshored to lower-cost teams. The consultant who scopes the matter at the diagnostic is the same one who signs the opinion, defends the structure in tax litigation, and sits across from the auditor when the inspection comes.
That continuity is the core deliverable. It is what makes the model fit situations where technical depth matters more than scale — corporate tax planning, recovery of credits, Transfer Pricing and adaptation to the Brazilian Tax Reform.

Work with the firm
Engagements begin with a diagnostic conversation directly with a senior consultant — no intake layers. The same consultant stays on the matter through to delivery.
