Fee exemption in a Brazilian concurso: who qualifies and how to ask

A fee exemption (isencao de taxa de inscricao) waives the registration payment for a specific concurso, but it is never automatic. A candidate must request it inside the window the edital sets, attach proof of meeting the stated criteria, such as enrollment in the Cadastro Unico for low-income families, and get that request approved before the regular registration deadline closes. Missing that window means paying the full fee, with no exception.

What actually qualifies someone for a fee exemption?

The federal rule, applied by most national concursos, grants exemption to a candidate registered in the Cadastro Unico (CadUnico) who belongs to a low-income family, generally defined by monthly per-capita income up to half a minimum wage or total family income up to three minimum wages. States and municipalities layer their own criteria on top through local legislation: some grant exemption to unemployed candidates, some to blood donors registered with a public program, some to candidates who already applied for a public defender’s assistance. None of these criteria apply automatically across concursos; each edital states, in its own exemption chapter, exactly which categories it recognizes for that specific selection.

How does a candidate actually request the exemption?

The candidate submits a formal request (requerimento de isencao) to the organizing body or the banca organizadora, through the same portal used for registration, during the exemption window the edital opens before the general registration period. The request needs the candidate’s Numero de Identificacao Social (NIS), the identifier tied to CadUnico registration, or whatever documentation the specific criterion demands. The organizing body then publishes a preliminary list of approved and denied requests, opens a short period for appeal, and issues a final decision before the regular registration deadline, so a denied candidate still has time to register and pay normally.

What happens if the exemption request is denied?

The candidate is notified through the result list the organizing body publishes and can still register for the concurso by paying the fee before the standard deadline, as long as that deadline has not already closed. Losing an exemption appeal is not the same as losing eligibility to compete: it only means paying rather than being waived. This is one of several concurso-specific procedures, alongside understanding what a cargo efetivo actually is, that trips up first-time candidates who assume rules from one selection carry over to another.

Does the CNU offer fee exemptions the same way?

The CNU, like other federal selections, opens an exemption window tied to CadUnico registration and other federally recognized criteria, published inside its own edital for each cycle. Because the CNU consolidates dozens of cargos and blocos into a single national selection, its exemption rules apply once across all of them rather than separately per agency, which is one of the structural simplifications we describe in how CNU blocks and cargos work.

Do security and police concursos apply different exemption rules?

The general federal criteria (CadUnico membership, low income) still form the base, but a police concurso such as PF agente may add or restrict categories inside its own edital, particularly because these selections carry additional stages, physical tests and background checks that some states link to distinct exemption categories for candidates already enrolled in specific social assistance programs. The rule to remember is structural, not a fixed list: always read the exemption chapter of that specific edital, never assume a category recognized in one concurso automatically applies in another.

Frequently asked questions

Is the fee exemption the same across every concurso in Brazil? No. Each edital defines its own exemption criteria and window, even though most federal selections converge around CadUnico-based low-income exemption. A criterion valid for one concurso is not automatically valid for another.

Can I request exemption after the registration deadline has passed? No. The exemption request window always closes before the general registration deadline, precisely so a denied candidate still has time to pay and register normally. There is no late exemption request once that window shuts.

Do I need to already be registered in CadUnico to request exemption? Yes, for the most common federal criterion. Registration in the Cadastro Unico, and having an active NIS, needs to exist before you submit the exemption request, since the organizing body checks that registration directly.

Does an approved exemption carry over to future concursos by the same agency? No. An exemption is granted for one specific selection process only. A new edital, even from the same conducting body, requires a new exemption request under whatever criteria that new edital states.

Where do I find the exemption rules for a specific exam? Inside that concurso’s own edital, in the chapter titled something like “Da Isencao da Taxa de Inscricao.” The exam pages on this site link to the official notice for each covered concurso for exactly this reason.
