It does not present a full set of financial statements (revenue, net income, or cash flow from operations) but focuses exclusively on fiscal outflows.

- States: R$ 29.6 billion.
- Municipalities: R$ 0.7 billion.

Material Changes vs. Prior Period
- Total Contributions: Increased compared to 1Q25 (R$ 65.7 billion), though the text explicitly highlights specific component changes rather than a total percentage.
- Federal Contributions: Increased by 8% compared to 1Q25.
- State Tax Payments: Increased by 13.4% compared to 1Q25. This was driven by higher ad rem ICMS rates on fuels effective January 1, 2026, and an increase in ethanol blending in gasoline from 27% to 30%.
- Municipal Taxes: Increased by 18.3% compared to 1Q25, reflecting service contracting activities subject to ISS-ST.
- Government Take: Decreased by 9% compared to 1Q25, primarily due to lower payments of Special Participation.
Outlook, Risks, and Unusual Items
- Regulatory Changes: A new Export Tax (IE) on crude petroleum and diesel fuel became effective March 12, 2026.
- Tax Policy: The report emphasizes Petrobras' role as a major taxpayer, noting it accounts for over 10% of total ICMS payments in 20 Brazilian states.
- Accounting Basis: The filing explicitly states that data is on a cash basis, which differs from accrual-based figures in the Statement of Value Added (DVA) found in full financial statements.
- Historical Context: Over the last four quarters, Petrobras contributed R$ 284.3 billion to the public treasury.
Investor Verification Checklist
- Verify the full 1Q26 financial statements (Form 20-F or equivalent) to reconcile cash-basis tax payments with accrual-based revenue and net income.
- Confirm the impact of the new Export Tax (IE) on future export margins and cash flows.
- Review the Q4 2025 Tax Report referenced in the text for details on tax risk management and compliance.
- Assess the sustainability of the 13.4% increase in state tax payments given the permanent change in ICMS rates and ethanol blending mandates.
- Investigate the drivers behind the 9% decrease in Government Take to determine if it reflects lower production volumes or pricing changes.
