Article 116, sole paragraph, of the Brazilian National Tax Code states that the tax authority may disregard legal acts or transactions carried out to conceal the occurrence of the taxable event or the nature of the elements of the tax obligation, subject to procedures to be established by ordinary law. The statute is the starting point, not an automatic answer. The assessment must reconstruct what was decided, documented, executed and recorded in the specific case.
The decision comes before the thesis
The operational question is not whether a structure is labelled “tax avoidance.” The question is whether, for a defined decision and deadline, the projected or completed acts have a legal basis, contemporaneous documentation, consistent execution and sufficient controls.
TaxUp treats estimated tax savings as one input to the case. The calculation must be reconciled with implementation costs, side effects, exposure by period and reversibility. The recommendation also records the fact that could reverse it; without that test, the matrix merely confirms the initial hypothesis.
Minimum input and information governance
The assessment starts only after the company can define the object. The minimum input includes:
| Input | Control question | Minimum record |
|---|---|---|
| Structure and parties | What is the sequence of acts and who participates? | flow, people and relevant relationships |
| Stage | Is the structure an idea, design, approval, implementation, ongoing operation or challenge? | current state and next milestone |
| Decision and deadline | What must be decided, by whom and by when? | decision-maker, owner and date |
| Expected effect | What is the effect by period? | tax, cost, cash and exposure |
| Evidence | What already exists and when was it produced? | agreements, minutes, studies, calculations, records and filings |
| Reversal fact | What would cause the company to adjust or stop the design? | verifiable document, event or conclusion |
The internal sponsor names the decision and deadline. Tax, legal, accounting and operational teams assemble the facts and reconcile the numbers under identified owners. If an audit, notice or procedural deadline already exists, that urgency is recorded before any optimization exercise.
A document created after the event is not treated as contemporaneous evidence. Missing information receives a gap status; contradictory information receives a conflict status. This distinction prevents a narrative from concealing what remains to be demonstrated.
Defensibility matrix
| Axis | Decision question | Expected evidence | Counter-test |
|---|---|---|---|
| Facts and structure | What will actually happen, in what order and between which parties? | flows, acts, agreements and records | does execution differ from the design? |
| Business decision | Which business problem does the transaction address? | studies, deliberations and alternatives considered, if any | was the rationale created only afterward? |
| Legal basis | Which provision authorizes, limits or characterizes the treatment? | number, excerpt and opened official source | is there a specific rule or adverse reading? |
| Execution | Do people, assets, functions and risks match the legal form? | observable operation and accountable owners | is any step merely formal? |
| Timing | When did each decision, document and act occur? | verifiable timeline | was the record created after the event? |
| Accounting and tax | Do the ledgers and filings reflect the design? | bookkeeping, policies and filings | is any treatment inconsistent? |
| Comparable decision | Which facts and taxes in the decision actually match? | full decision and a differences chart | did the outcome depend on a fact absent here? |
| Materiality | What is the effect, cost and exposure by period? | reconciled calculation and assumptions | does cost or exposure exceed the effect? |
| Reversibility | How can the structure be stopped, corrected or exited? | plan, cost and dependencies | is the decision difficult to reverse? |
| Implementation | Who approves, executes, records and reviews? | owners, controls and milestones | does a control depend on missing data? |
“Present,” “gap” and “conflict” are working states in the matrix, not autonomous legal conclusions. The weight of each axis depends on the specific case; there is no automatic score that converts points into legality.
Four outcomes, including do not proceed
Proceed with conditions applies when facts, legal basis, evidence and execution support the next step, but controls must accompany implementation. Adjust and reassess keeps the decision open while a correctable conflict is addressed.
Do not proceed is an express outcome when form and execution diverge, minimum evidence is missing, materiality is unfavorable or reversibility is inconsistent with the exposure. Investigate further is not provisional approval: it suspends the recommendation until the decisive source, document or fact is confirmed.
NTC article 116 and Civil Code article 167: different objects
Article 167 of the Brazilian Civil Code declares a simulated legal transaction null and allows the concealed transaction to survive if it is valid as to substance and form. Article 116, sole paragraph, of the National Tax Code instead addresses administrative disregard in tax matters and retains an express procedural condition.
Article 108, paragraph 1, of the National Tax Code also sets a textual limit: analogy may not result in the assessment of a tax that is not provided by law. That limit does not decide by itself how a panel characterizes the facts of an assessment. The connection between the legal planes depends on the applicable rule, taxable object, evidence and reasoning in the case.
Eletrozema and Gerdau: two individual case slices
Eletrozema: convergence of the facts in that proceeding
In Decision 1401-007.754, proceeding 10600.720090/2016-19, the 1st Ordinary Panel of the 4th Chamber of CARF’s 1st Adjudication Section heard the case on December 17, 2025, with Luiz Augusto de Souza Gonçalves as reporting councilor. Eletrozema’s voluntary appeal was unanimously denied on the merits; the panel reduced the qualified penalty on its own motion and resolved the isolated estimated-payment penalty point through the chair’s tie-breaking vote.
Among the defense arguments recorded in the proceeding, the taxpayer alleged that the products were distinct; that it had organizational freedom; that shared management was compatible with keeping the activities separate; that the entities had operating capacity; that there was an alleged absence of activity with third parties; and that there was an alleged absence of fraud, willful misconduct or collusion. These are the taxpayer’s allegations in that proceeding, not facts adopted by TaxUp or general conclusions of the panel.
The opinion itself preserves an important counterpoint: no element in the record, viewed alone, definitively proved the tax authority’s conclusion. Its reasoning depended on the convergence of the full set. In its examination of the silent partnerships in that proceeding, the opinion recorded no practical distinction between the companies’ activities and held that the facts, taken together, distorted the arrangement. The limit is individual: the decision creates no presumption for another silent partnership, industry or sequence of acts.
Gerdau: a narrow favorable stock-option illustration
In Decision 9202-010.506, proceeding 16682.721015/2013-46, the 2nd Panel of the Higher Chamber of Tax Appeals heard Gerdau Aços Longos’s special appeal on November 22, 2022, with João Victor Ribeiro Aldinucci as reporting councilor. The appeal was unanimously admitted and granted by majority, with four dissenting votes.
The majority stated, in the official Portuguese text, that “A onerosidade decorre do fato de que o empregado ou administrador paga o preço do exercício estipulado” and recorded that no separate option premium had been paid, only the amount required to purchase the shares. This is a narrow favorable illustration tied to the facts of that stock-option plan and the object assessed in the proceeding. It does not transfer the result to every equity plan, variable compensation arrangement or tax structure without factual comparison.
Adversarial test before the recommendation
Before closing the matrix, the responsible team attempts to refute the working hypothesis. The test is documented in five steps:
| Step | Test | Expected record |
|---|---|---|
| 1 | State the strongest countercase | the rule, fact or reading that most weakens the design |
| 2 | Look for divergence between form and execution | comparison of contracts with actual people, assets, systems, payments and records |
| 3 | Separate contemporaneous evidence from later rationale | date and owner of each document |
| 4 | Compare a decision through its decisive fact | tax, period, instrument, outcome, votes and material differences |
| 5 | Record the reversal fact | the event that requires adjustment, suspension or a decision not to proceed |
Hypothetical example: the business separation appears only in the contracts; people, assets and systems remain integrated; the rationale is produced after the decision; the accounting does not reconcile with the cash flow; total cost exceeds the net effect; and unwinding the agreements is costly. The coherent outcome is do not proceed with the current design. Reopening requires new facts, verifiable execution and a reconciled calculation. The example describes no client and does not characterize an operation in the abstract.
Scope, deliverable, owners, channel and limits
| Element | Definition |
|---|---|
| Initial scope | one defined decision, its sequence of acts, period, parties, effects and deadline |
| Possible deliverable | fact map, evidence gaps, counterarguments, decision matrix, conditions and reopening events, as contracted |
| Company owner | sponsor who names the decision and deadline; tax, legal, accounting and operational teams provide facts and reconcile numbers |
| TaxUp owner | team named in the confirmed scope, with coordination, assumptions, pending items and limits recorded |
| Initial channel | booking form; confidential documents should not be submitted through the open field |
| Document channel | defined after the initial conversation, scope verification and, where applicable, a conflict check |
| Outside initial scope | formal legal opinion, implementation, litigation, prediction of authority acceptance and result guarantee, unless expressly contracted |
The initial conversation defines the problem; it does not validate the structure. A company may begin with the tax-planning pillar, the Brazilian tax-regime comparison or the analysis of holding companies, depending on the actual decision. If an assessment or dispute already exists, the intent belongs to tax litigation.
