Campaign financing in Brazil is essential to ensure fair and competitive elections. In recent years, the system has undergone significant changes, such as the prohibition of corporate donations and the creation of the Special Campaign Financing Fund (FEFC). 

However, despite the progress, challenges such as monitoring the use of resources, combating undeclared funds, and ensuring transparency in accounting remain a concern.

Furthermore, the growth of crowdfunding ( electoral crowdfunding ) and the use of new technologies in oversight open new perspectives for the future. In this article, we explore the rules, challenges, and trends of electoral financing, highlighting the importance of transparency and fairness in the democratic process.

1. Constitutional foundations of electoral financing

Campaign financing in Brazil is a highly relevant issue for democracy. The Federal Constitution establishes guidelines to guarantee fair elections, preventing the abuse of economic power and ensuring national sovereignty.

One of the fundamental pillars is the prohibition of financing by foreign entities. Article 17, §1, of the Constitution prohibits political parties from receiving financial resources from abroad. This rule seeks to prevent external interference in the electoral process and preserve the country's political autonomy.

Furthermore, Article 14 ensures the fairness of elections by establishing limits on the abuse of economic power. The goal is to prevent candidates with greater financial resources from gaining an unfair advantage, thus compromising equality among competitors.

Another important point is the transparency regarding the origin of the resources used in campaigns. The Constitution and electoral legislation stipulate that parties must account to the Electoral Court, ensuring that financing is within legal limits and respects the principles of morality and publicity.

The financing model also reflects the democratic principle. The ban on corporate donations, decided by the Supreme Federal Court (STF) in 2015, sought to prevent large corporations from influencing elections, strengthening the direct participation of society in the electoral process.

Thus, the financing of electoral campaigns in Brazil is structured to balance the need for resources with the preservation of equality among candidates and transparency in the use of public and private money.

2. Types of campaign financing in Brazil

Campaign financing in Brazil is structured in different ways, each with specific rules. Understanding these methods is essential to ensuring the transparency and legality of the electoral process.

3.1 Party fund and special campaign financing fund (FEFC)

The Party Fund, officially called the Special Fund for Financial Assistance to Political Parties, is intended to cover the daily expenses of political parties. Its resources come from electoral fines, pecuniary penalties, and budgetary allocations from the Federal Government. 

The distribution is carried out by the Superior Electoral Court (TSE), with 1% of the total divided equally among all parties with registered statutes and 99% distributed according to the number of votes obtained in the last election for the Chamber of Deputies.

The Special Campaign Financing Fund (FEFC), known as the Electoral Fund, is a specific public fund for financing electoral campaigns. Established by Law No. 9.504/1997, articles 16-C and 16-D, its management and distribution follow guidelines established by TSE Resolution No. 23.605/2019.

3.2 Donations from individuals

Individuals can contribute financially to election campaigns, respecting legal limits. Donations should not exceed 10% of the gross income declared by the donor to the Federal Revenue Service in the year prior to the election. Contributions can be made by electronic transfer, credit card, or crowdfunding.

3.3 Self-financing

Candidates can finance their own campaigns, provided they observe the spending limits established for each position. This practice allows for greater control over the resources used, but must be carried out transparently and within legal norms.

3.4 Prohibition of donations from legal entities

Since 2015, with the decision of the Supreme Federal Court (STF), corporate donations to election campaigns have been prohibited. This measure aims to reduce economic influence in the electoral process and promote greater equality among candidates. 

4. Challenges in transparency and oversight of financing

Campaign financing in Brazil faces constant challenges related to transparency and oversight. Ensuring that resources are used correctly and legally is essential to strengthening democracy and preventing abuses of economic power.

4.1 Use of public resources: how to ensure that funds are used correctly?

The use of public funds in election financing requires strict rules and efficient control mechanisms. Both the Party Fund and the Special Campaign Financing Fund have specific purposes and cannot be used for candidates' personal expenses or for non-election purposes.

To ensure the proper use of these funds, political parties must follow detailed rules from the Superior Electoral Court (TSE) and provide detailed accounts of every expense incurred. Transparency is fundamental, and failure to comply with the rules may lead to the suspension of future transfers and even sanctions against parties and candidates.

4.2 Accountability: obligations of candidates and political parties

All candidates and parties must account for their income and expenses during the elections. This information must be submitted to the TSE (Superior Electoral Court) and made available for public consultation.

Among the main obligations are:

  • Detailed record of donations received, including donor identification.
  • Proof of expenses, with receipts and invoices.
  • Transparency in financial transactions, using bank accounts specifically for the campaign.

Failure to provide accountability or withholding information may result in sanctions such as fines, suspension of transfers from the Party Fund, and even the revocation of mandates in serious cases.

4.3 Technological advances in inspection: the use of artificial intelligence and digital audits

Technology has played a crucial role in modernizing election oversight. The use of artificial intelligence (AI) and digital audits allows for a more efficient and agile analysis of campaign accounts.

The TSE (Superior Electoral Court) already implements tools that cross-reference banking, tax, and accounting information to identify irregularities. In addition, algorithms analyze patterns of suspicious financial transactions, helping to detect fraud.

Another important advancement is the availability of real-time data, allowing citizens, the press, and oversight bodies to monitor campaign spending. The digitization of the accountability process increases transparency and hinders illicit practices.

4.4 Off-the-books campaign financing and electoral corruption: measures to combat illicit financing

Off-the-books campaign financing is one of the main challenges in election campaign financing. It consists of raising and using funds without official declaration, which violates electoral law and can result in crimes such as money laundering and corruption.

To combat this practice, several measures were implemented:

  • Stricter oversight by the TSE (Superior Electoral Court) and the Federal Revenue Service., through the cross-referencing of financial data.
  • More severe punishmentsincluding hefty fines and even imprisonment for those who engage in off-the-books accounting practices.
  • Encouraging transparency, requiring that all donations and expenses be recorded and disclosed.

The fight against illicit campaign financing requires constant oversight and active participation from society. The greater the transparency in the electoral process, the lower the chances of corruption and undue economic influence.

Ensuring fair and transparent election financing is essential to strengthening democracy and allowing elections to be held in a balanced way, without undue privileges.

5. Future prospects for campaign finance

Campaign financing in Brazil is constantly changing, with proposals to make it more transparent and equitable. Among the main legislative initiatives are the creation of a stricter spending cap, increased public funding, and the possible reintroduction of corporate donations under more restrictive rules.

International experiences show different approaches. Germany adopts a mixed model, while France prioritizes public funding and the United States maintains a predominantly private system, but with strong transparency mechanisms.

Civil society plays a key role in monitoring election spending, using digital platforms and transparency initiatives to report irregularities and strengthen trust in elections.

Technology is also transforming election financing. Crowdfunding allows candidates to raise small donations online, expanding popular engagement. However, it is necessary to regulate these practices to ensure transparency and prevent fraud, with solutions such as the use of blockchain to track donations.

The closing thought

Campaign financing is an essential pillar of democracy, guaranteeing a level playing field for candidates and transparency in the use of resources. The evolution of regulations, coupled with strengthened oversight and the use of new technologies, is fundamental to preventing abuses and reinforcing trust in the electoral process.
