Brazil’s president can propose federal tax and budget changes and nominate Central Bank leaders, but cannot unilaterally rewrite tax law, spend beyond legal appropriations, or direct monetary policy. Congress and the Senate have approval roles, while constitutional and statutory rules limit executive power.
Which decisions belong to the president, Congress, and the Central Bank?
The president has substantial influence over the government’s agenda and administration, but influence is not the same as unilateral legal authority. The division of power differs by subject:
| Area | What the president can initiate or do | Who else decides, and what constrains the result |
|---|---|---|
| Taxes | Propose federal tax legislation and lead the administration’s tax agenda. | Congress legislates; the Constitution allocates taxing powers among the Union, states, Federal District, and municipalities. Constitutional changes require the constitutional amendment process. |
| Spending | Submit budget proposals and administer the enacted federal budget. | Congress considers the budget. Appropriations, mandatory expenditure, and fiscal rules constrain execution. |
| Central Bank | Nominate the Bank’s president and directors. | The Senate approves nominees. Statute gives the Bank autonomy, fixed-term leadership, and responsibility for conducting monetary policy. |
The framework described here draws on Brazil’s Constitution as amended by Constitutional Amendment 132 of 2023, Complementary Law No. 179 of 2021, and the government-hosted English translation of the Fiscal Responsibility Law marked revised in 2025. For close legal interpretation or a specific budget year, the consolidated Portuguese texts and that year’s budget laws control; the cited materials do not establish whether later amendments changed those provisions.
What can the president change about taxes?
Federal tax proposals require legislation
The president can make federal tax policy a priority and submit proposed changes through the legislative process. A proposal is not law simply because the president supports it: Congress must act on legislation, and the president’s role in signing or vetoing a bill occurs within that process. The president cannot use an executive decision to permanently rewrite the tax system.

Tax authority is divided across levels of government
The Constitution assigns taxing powers separately to the Union, states, Federal District, and municipalities. A president may shape federal policy, but cannot take over state or municipal tax powers by decree. Changing the Constitution’s allocation of those powers requires a constitutional amendment rather than ordinary presidential action.
The 2023 reform created shared institutions
Constitutional Amendment 132 of 2023 changed the Constitution’s tax provisions and established a framework that includes the IBS Management Committee. The constitutional text describes that committee as a public entity with technical, administrative, budgetary, and financial independence, with state and municipal representation. The arrangement makes implementation and governance a shared institutional matter—not a system under unilateral presidential command.

How much control does the president have over federal spending?
The president proposes; Congress considers the budget
The Constitution provides for a multi-year plan, a budget-guidelines law, and an annual budget law. The president’s government prepares and submits budget proposals, while Congress considers them. Once an annual budget is in force, the Executive administers its implementation, but authorization and legal constraints matter: the president cannot spend outside enacted appropriations or treat every outlay as freely adjustable.
Budget authority and cash execution are distinct
Under the Fiscal Responsibility Law, the Executive establishes financial programming and a monthly disbursement schedule within 30 days after the budget is published. That schedule governs the timing of financial execution; it does not turn the whole budget into discretionary spending or erase the limits imposed by appropriations and other laws.
Revenue shortfalls can trigger restrictions
If revenue projections indicate that fiscal targets are at risk, the law calls for restrictions on commitments and financial execution in accordance with the Budget Guidelines Law. The restrictions do not apply to legally or constitutionally mandatory expenditure, debt service, and certain other specified categories. The precise room to adjust spending therefore depends on the applicable year’s budget laws and the legal classification of each expense.
Can Brazil’s president control the Central Bank?
The president nominates leaders, but the Senate must approve them
Under Complementary Law No. 179 of 24 February 2021, the president nominates the Central Bank’s president and directors, subject to Senate approval. Their terms last four years and are staggered across the presidential term. The statute defines the Central Bank as a special autonomous agency without ministerial subordination and provides for technical, operational, administrative, and financial autonomy.
Rank #4
Monetary policy is not a presidential instruction
The Monetary Policy Council sets monetary-policy targets, and the Central Bank has exclusive responsibility for conducting the monetary policy needed to meet them. The law makes price stability the Bank’s fundamental objective, alongside financial stability and efficiency, smoothing fluctuations in economic activity, and promoting full employment. The president’s ability to nominate Bank leaders does not give the president day-to-day authority to set monetary policy.
Removal is limited by statute
The statute lists grounds for ending a leader’s term, including resignation, incapacity, specified final or collegial convictions, and proven recurring insufficient performance. For removal on the insufficient-performance ground, the Monetary Policy Council must submit a proposal and the Senate must approve it by absolute majority. The appointment power is therefore not an at-will dismissal power.

The Constitution separates currency and Treasury financing
The Constitution assigns currency issuance exclusively to the Central Bank and prohibits it from lending directly or indirectly to the National Treasury. It does permit the Bank to buy and sell Treasury securities to regulate the money supply or interest rates. Those monetary-policy operations are distinct from the government’s budget and fiscal relationship with the Bank.

When a candidate or president says they will change a tax, increase or cut spending, or alter Central Bank policy, ask three questions:
- Who can initiate it? Is the president proposing a bill or budget, nominating an official, or claiming direct authority to act?
- Who must approve or implement it? Does it require action by Congress, Senate approval, or a shared institution such as the IBS Management Committee?
- What legal constraint applies? Is the action limited by the Constitution, an appropriation, fiscal rules, fixed terms, or the Central Bank’s statutory autonomy?
A promise may be politically influential even when the president cannot deliver it alone. The distinction is whether the president can set a proposal in motion, whether another institution must authorize it, and whether the law limits what can happen after approval.
