Boutique-format Brazilian tax consultancy for foreign founders, multinationals, and Brazilian groups operating internationally. Direct consultant-led work in English, French and Portuguese — nine integrated practice areas, offices in São Paulo, Rio de Janeiro and Brasília.
Three operating decisions — not slogans — that change the relationship between client and adviser.
No layered associates. No rotating juniors between meetings. No work offshored to lower-cost jurisdictions. The consultant who scopes your matter at the diagnostic is the same one who signs the final opinion, defends the structure in CARF, and sits across from the auditor when the inspection comes. That continuity is the core deliverable, not a marketing claim.
Brazilian tax law is one of the most jurisprudence-driven systems in the world — STJ and STF rulings carry binding effect, CARF precedents reshape industry practice, and infraconstitutional regulation moves quarterly. We invest in continuous study of jurisprudence and academic literature so each recommendation is anchored in verifiable precedent — not adapted from a generic playbook.
Technical material is produced in English and Portuguese from the start — not translated after the fact. Communication with foreign CFOs, tax directors, and parent companies happens in English directly, with no translation layer. Coordination with foreign counsel runs under OECD standards (Local File, Master File, BEPS Action 13). French is also available when relevant for European matrices.
Nine practice areas documented in English, covering the full corporate tax cycle of a Brazilian operation — from the border to the higher courts.

It is a thesis.
TaxUp is a boutique Brazilian tax consultancy with three offices — São Paulo, Rio de Janeiro and Brasília — working in English, Portuguese and French. Unlike the Big 4 and traditional firms, every engagement is run directly by the responsible consultant, with the focus on the thesis, the strategy and a measurable result.
A senior consultant studies the matter, maps the opportunities and builds the argument. Internal systems verify SPED and EFD at volume — they never replace the legal reasoning.
No outsourcing and no intermediate managers. You speak with the consultant who runs the engagement, from the diagnostic through to execution.
On tax credit recovery you pay only when the credit is approved and actually used by the company — no upfront cost.
