Auditor-Fiscal da Receita Federal common mistakes

Auditor-Fiscal da Receita Federal · Understand the traps and how to avoid them.

Mistake 1

On interpretação de texto items, choosing the alternative that matches the candidate's prior knowledge of the subject rather than what the passage actually states, and treating an inference as if it were an explicit assertion.

Time pressure pushes candidates to skim; familiar vocabulary from Direito Tributário or Economia triggers recognition-based answering, and the difference between 'o texto afirma' and 'o texto permite concluir' is not checked.

What to do instead

For each item, locate and mentally mark the exact trecho that supports the answer, and reject any alternative containing a claim not anchored in that trecho; classify the command verb (afirma, infere-se, conclui-se) before reading the options.

Mistake 2

Applying regência, crase, and concordância by ear in the redação and in the objetivas, particularly with verbs like assistir, aspirar, implicar, and with 'haver/existir' constructions.

Colloquial Brazilian Portuguese usage diverges from the norma padrão precisely in these structures, so what sounds correct is often wrong; candidates memorized rules in isolation but never contrasted minimal pairs.

What to do instead

Keep a personal error log of only the constructions missed in simulados, write one correct and one incorrect minimal pair for each, and revise the log weekly; in the redação, reserve the final 10 minutes for a targeted pass over crase, regência verbal, and paralelismo.

Mistake 3

In Raciocínio Lógico, solving proposições compostas and argument validity by intuition instead of building the truth table or applying the inference rules systematically, and confusing negação with contrapositiva.

Items are designed so the intuitively plausible alternative is the logically invalid one; candidates also misread 'somente se', 'se e somente se', and 'a menos que' as equivalent connectives.

What to do instead

Translate every enunciado into symbolic form (P, Q, conectivos) before evaluating; for equivalências, memorize the three canonical pairs (negação de condicional, contrapositiva, De Morgan) and test each alternative by constructing a counterexample assignment.

Mistake 4

Treating estatística descritiva and probabilidade items as formula recall, applying the wrong measure (média vs. mediana under assimetria, variância populacional vs. amostral) or misinterpreting intervalos de confiança as probability statements about the parameter.

Formulas are memorized without the conditions of use; the distinction between parâmetro and estimador and the effect of outliers on measures of central tendency are under-practiced.

What to do instead

For each item, first write the nature of the variable and the shape of the distribution, then select the measure; drill a fixed set of 'which measure and why' questions and explicitly state the frequentist interpretation of the confidence interval in one sentence.

Mistake 5

Answering Direito Constitucional items from general civics knowledge, without distinguishing controle difuso from concentrado, or the effects of ADI, ADC, and ADPF, and without checking whether the question concerns validade, vigência, or eficácia da norma.

The exam tests technical distinctions (efeitos erga omnes vs. inter partes, efeito repristinatório, modulação de efeitos) that casual reading of the CF/88 does not supply; candidates conflate the STF's roles.

What to do instead

Build a comparison table for each remédio and each ação de controle (competência, legitimidade, objeto, efeitos, possibilidade de liminar e de modulação) and rehearse it against past-style hypotheticals until the distinctions are automatic.

Mistake 6

In Direito Administrativo, classifying atos and vícios by the label that sounds most severe, rather than by the legal regime: confusing anulação with revogação, decadência with prescrição, and atributos do ato (presunção, autoexecutoriedade, imperatividade) with each other.

The concepts overlap in ordinary language, and the different prazos and efeitos (retroativos vs. ex nunc) are studied separately instead of side by side.

What to do instead

For every ato administrativo item, answer three fixed questions in writing: é legal ou conveniente? os efeitos são ex tunc ou ex nunc? há prazo decadencial da Administração? Only then read the alternatives.

Mistake 7

In Direito Tributário, jumping to the CTN article number without checking the constitutional limits first, and misapplying the regras-matriz de incidência: confusing fato gerador with obrigação tributária, lançamento with crédito tributário, and suspensão with extinção.

The discipline is studied as a list of articles, so candidates cannot reconstruct the sequence competência → hipótese → fato gerador → obrigação → crédito → lançamento → suspensão/extinção/exclusão when an item scrambles the order.

What to do instead

Draw the full chain from competência to exigibilidade for each tributo before answering; for any item naming a dispositivo, also name the constitutional principle or article that constrains it, and verify the item does not invert the chain.

Mistake 8

In Contabilidade e Auditoria, computing lançamentos and demonstrações without first classifying the accounts (patrimonial vs. resultado, circulante vs. não circulante) and without checking the regime de competência; in auditoria, answering by the 'most conservative' procedure instead of by risco and materialidade.

Candidates memorize formulas (depreciação, ajuste a valor presente, equivalência patrimonial) but skip the classification step, so the arithmetic is right and the accounting treatment is wrong; auditoria is treated as common sense rather than as a risk-based methodology.

What to do instead

Before any calculation, write the debit and credit accounts and their classification; for auditoria items, identify the assertion being tested (existência, integralidade, valoração, direitos e obrigações) and the risk level before selecting the procedure.

Mistake 9

In Economia, Finanças Públicas e AFO, confusing the concepts that share vocabulary: déficit nominal vs. primário vs. operacional, receita efetiva vs. realizada, empenho vs. liquidação vs. pagamento, and the LRF limits on despesa de pessoal and dívida.

These pairs differ by one qualifier and are learned in isolation; the exam exploits the qualifier, and candidates answer from the general idea rather than the precise definition.

What to do instead

Maintain a glossary of minimal pairs with the defining formula or legal basis for each; for AFO items, trace the estágio da despesa explicitly and cite the LRF article or the Constituição provision that grounds the limit before choosing.

Mistake 10

In Comércio Internacional e Aduana, applying the Regulamento Aduaneiro from memory without checking the specific regime, and classifying mercadorias by the product name rather than by the RGI and Notas Explicativas do SH; in valoração, using the invoice value without testing the métodos in order.

The SH and the valoração aduaneira are rule-ordered systems, but candidates learn examples instead of the method: they skip the Regras Gerais de Interpretação and jump to the first method of valoração without verifying that the previous one is inapplicable.

What to do instead

For classification, always state the posição, then apply RGI 1 and the notas de seção/capítulo in writing before considering RGI 2–6; for valoração, list the six métodos in order and justify in one line why each prior method fails before applying the next.
