Spending Review of Brazil’s National Housing Initiative (PMCMV): Lessons for Ensuring Accountability in the Allocation and Expenditure of Government Funds

By André Farias, Senior Auditor of Brazilian Federal Court of Accounts (TCU)

Abstract

While financial audits of public expenditures are a cornerstone of government accountability, a critical dimension of public finance often escapes equivalent scrutiny: revenue losses through tax expenditures. In 2023–2024, Brazil’s Supreme Audit Institution (SAI Brazil), conducted an audit of federal tax benefits which revealed significant governance gaps and risks to fiscal sustainability.

This article presents a case study of that audit, by detailing how Brazil’s audit body assessed the efficiency of tax benefit programs and their actual economic impact, aiming to improve transparency in public finances. It concludes explaining what lessons were learned for other SAIs seeking to enhance oversight of fiscal policy beyond traditional financial audit procedures.

Introduction

Supreme Audit Institutions (SAIs) have long served as guardians of public spending. However, in an era of rising fiscal pressures and growing reliance on tax incentives to stimulate economic sectors, public accountability must also extend to revenue-side decisions. Tax breaks and incentives often lead governments to lose as much revenue as they spend directly. Yet, these losses are rarely subject to the same scrutiny or transparency.

Recognizing this imbalance, SAI Brazil initiated a series of reviews culminating in a comprehensive audit of federal tax expenditures as part of its 2023 assessment of the Union’s annual accounts. The findings sparked national debate and highlighted urgent reforms needed to bring fiscal governance in line with constitutional principles of efficiency, transparency, and equity.

Background: The Scope and Scale of Tax Expenditures in Brazil

According to TCU’s 2024 reporting on the 2023 federal accounts, the Brazilian government forfeited an estimated R$518.9 billion (USD 105 billion) in tax revenues due to a wide range of exemptions and incentive programs. This figure represents 5.9% of the country’s GDP, and nearly one-quarter of total government revenues.

More strikingly, 32 new tax benefit programs were introduced in 2023 alone, with projected costs of R$213.6 billion through 2026. TCU flagged that many of these incentives lacked ex-ante impact assessments, monitoring mechanisms, or clear social or economic justification. In some cases, long-standing exemptions were renewed despite consistent underperformance in delivering intended public benefits.

Audit Methodology

The audit was conducted as part of TCU’s Report and Preliminary Opinion on the Accounts of the Federal Government, led by Minister Vital do Rêgo. The scope included:

• Inventory and classification of all active tax expenditure programs.
• Analysis of projected vs. realized fiscal impact using data from Federal Revenue Service and the National Treasury.
• Cross-examination of tax benefits and policy outcomes, including employment generation, regional development, or industrial growth.
• Review of legislative practices concerning the approval and renewal of tax incentives.
• Comparative international benchmarking, focusing on OECD guidelines for transparency and control of tax expenditures.

Key Findings

1. Lack of Strategic Planning and Performance Criteria

The TCU observed that the Executive Branch rarely subjects tax expenditure policies to the same planning rigor required for public spending. Few programs had established objectives, measurable targets, or performance indicators. As a result, many tax benefits functioned as quasi-permanent subsidies with little oversight or feedback on their effectiveness.

2. Fiscal Risk and Budgetary Constraints

The unchecked expansion of tax expenditures contributed to the structural fragility of Brazil’s public finances. The R$518.9 billion in foregone revenues far exceeded all federal investments and rivaled major mandatory spending categories such as pensions or healthcare. This dynamic undermines budget credibility and restricts fiscal space for discretionary investments.

3. Regressive Distribution of Benefits

The audit showed that a disproportionate share of tax benefits favored large corporations and wealthier sectors. For instance, state-owned oil company Petrobras and mining giant Vale received R$29.5 billion and R$19.2 billion respectively in tax relief, without clear public returns. Meanwhile, smaller businesses or vulnerable populations benefited minimally from the existing tax architecture.

4. Governance Gaps in the Legislative Process

TCU highlighted that many tax incentives were introduced or extended through provisional measures or last-minute amendments in budget discussions, bypassing structured review. Some programs lacked cost ceilings or sunset clauses, allowing them to persist indefinitely without reevaluation.

Recommendations

In its final opinion on the 2023 accounts (Decision n. 1534/2024 – Plenary), TCU issued concrete, actionable recommendations:

• Impose a prudential cap on total tax expenditures as a percentage of federal revenues.
• Suspend the creation of new exemptions while the federal budget remains in deficit.
• Mandate ex-ante and ex-post impact evaluations for all tax benefit programs, aligning with international standards such as those from the OECD and IMF.
• Enhance transparency by expanding public disclosure of beneficiaries, fiscal cost estimates, and expected outcomes of tax policies.
• Institutionalize periodic review mechanisms for existing programs, including automatic sunset provisions unless renewed based on performance.

These measures aim to rebalance Brazil’s fiscal governance framework and improve the effectiveness and fairness of public finance instruments.

Public and Policy Impact

The audit-identified weaknesses in Brazil’s National Housing Initiative (PMCMV)’s financial management and monitoring have had—and may continue to have—several consequences for the program’s public impact and policy outcomes:

• Harm to Transparency and Social Oversight: Inconsistent and unreliable data on how funds are applied and on program results undermine the program’s transparency and make auditing difficult. This prevents society—including non-governmental organizations, which are implicit in the concept of social oversight—from tracking and scrutinizing the public policy.
• Difficulty Measuring Effectiveness: The lack of robust monitoring and up-to-date indicators—such as changes in the housing deficit—weakens the ability to assess whether the program is effectively meeting its core objectives. This limits decision-making and policy improvements aimed at better serving the population’s needs.
• Risk of Project Interruptions and Unmet Goals: Financial difficulties and divergent spending forecasts signal a risk of construction stoppages due to erroneous projections of cash disbursements. Issues like delayed payments to contractors and untimely monitoring contribute to an accumulation of halted projects, directly affecting beneficiaries.
• Inefficient Use of Public Resources: Problems such as the improper use of outstanding payables, expenditures without prior commitment, and accounting shortcomings reveal deficiencies in financial management. Failure to observe the accrual basis results in an undervaluation of federal assets, complicating both asset and financial management.
• Compromised Accountability: The lack of reliable data and adequate monitoring impairs the government’s ability to report transparently and accurately to society on PMCMV implementation and results.

In summary, the lessons learned point to an urgent need to improve information management, results monitoring, and accounting and financial procedures to ensure the transparency, reliability, efficiency, and effectiveness of the PMCMV and future housing programs.

What other SAIs can learn from this TCU’s spending review audit

The audit of PMCMV, with an emphasis on its financial management, revealed several weaknesses and highlighted key lessons for managing large-scale public programs:

• Critical, Unified Data Management: There were extensive and worrying divergences and inconsistencies in financial data among the Ministry of Regional Development (MDR), Caixa Bank (the operational manager), and the other financial agents. The decision mentioned the apparent absence within the program of a clear, objective accounting procedure. This shows an imperative need for a joint, robust information-management plan to ensure consistent, reliable, and timely data.
• Essential Results Monitoring and Evaluation: After more than ten years, mechanisms for evaluating outcomes were still deemed incipient. A prior audit had already recorded the precarious monitoring of PMCMV results. The housing-deficit indicator has been outdated since 2015, blocking any assessment of recent impact, showing that continuous monitoring and evaluation are indispensable for refining public policy.
• Program-Specific Accounting Segregation: The audit found no segregation of accounts within the Residential Lease Fund (FAR) for PMCMV-Companies and the FAR sub-programs. This prevents clear data on total costs and the sources and uses of funds for each program. This remind us that resources must be segregated among different housing programs for clarity and better management.
• Careful Financial and Budgetary Planning: Although part of the analysis was referred to another proceeding, initial findings showed insufficient federal-budget resources and issues such as using outstanding payables from prior years. This point emphasizes how precise budgetary and financial planning is crucial.
• Compliance with Public-Sector Accounting Standards: Failure to use the accrual basis to record some beneficiaries’ financial participation in the MDR’s accounts also violated the Public-Sector Accounting rules. This led to an undervaluation of the Union’s assets and difficulty in forecasting future program results, showing that accounting records must strictly follow standards to correctly reflect rights and obligations.

Conclusion

As governments worldwide seek to reconcile fiscal discipline with inclusive development, the oversight of tax expenditures becomes imperative. Brazil’s TCU approached this complex issue with a firm strategy, delivering practical insights that prompted real reforms. 

This shows that tax oversight can be both technical and transformative. By doing so, it not only safeguarded billions in public resources but also strengthened the foundations of democratic governance. 

For the international audit community, this case underscores that effective public finance auditing must look beyond spending into the often-hidden world of tax incentives and their real impact on society.
