BRAZIL Law and Practice Contributed by: Paulo Honório de Castro Júnior and Bruno Marques Feitosa, William Freire - Advogados Associados

In practice, tax audits apply a substance-over-form approach. Transactions lacking economic rationale or business purpose may be recharacterised. Admin - istrative courts increasingly examine economic sub - stances, particularly in cross-border restructurings, intercompany financing and treaty-based structures. Transfer Pricing and Thin Capitalisation Brazil’s transfer pricing regime, recently aligned with the arm’s-length principle, requires related-party trans - actions to reflect market conditions. The tax authori - ties may make primary adjustments and impose pen - alties where pricing deviates from comparables. Thin capitalisation rules restrict the deductibility of interest paid to foreign related parties, applying fixed debt-to-equity ratios. Payments exceeding statutory thresholds are non-deductible, and enhanced scrutiny applies to transactions involving low-tax or privileged tax regimes. Controlled Foreign Company Rules Brazil operates strict CFC rules. Profits of controlled foreign entities must be included annually in the Bra - zilian parent’s taxable base, regardless of distribu - tion. This mechanism limits deferral strategies and addresses profit shifting to low-tax jurisdictions. Withholding Taxes and Blacklist Regimes Cross-border payments to jurisdictions classified as low-tax or underprivileged regimes are subject to aggravated withholding tax rates and stricter deduct - ibility requirements. Taxpayers must demonstrate the identity of the beneficial owner and the operational capacity of the foreign entity. Exchange of Information and Reporting Brazil participates in the automatic exchange of finan - cial information under the Common Reporting Stand - ard (CRS) and implements country-by-country report - ing for large multinational groups. These transparency tools support risk assessment and detection of base erosion strategies. Penalties and Criminal Enforcement Non-compliance may result in significant administra - tive penalties, including fines of 75% of unpaid tax, increased to 100% in cases of fraud. Criminal pros -

ecution may also apply under tax crime legislation, particularly where wilful misconduct or falsification is established. 5.3 Blacklists and Non-Cooperative Jurisdictions List of Low-Tax and Privileged Jurisdictions Brazil maintains two distinct lists for tax purposes: • low-tax jurisdictions (commonly referred to as “blacklisted jurisdictions”), defined as countries or dependencies that (i) do not tax income or (ii) apply a maximum income tax rate below 17%; and • privileged tax regimes, which refer not to entire jurisdictions but to specific legal entities or regimes that benefit from harmful preferential tax treatment. Both lists are issued and periodically updated by the RFB. Tax Consequences Transactions involving entities located in such jurisdic - tions are subject to stricter tax treatment. The main consequences include: • increased withholding tax – payments of interest, royalties and certain service fees are subject to a 25% withholding income tax rate (instead of the standard 15%); • application of transfer pricing rules: transfer pricing rules apply regardless of whether the counterparty is related; • stricter thin capitalisation limits – a reduced 0.3:1 debt-to-equity ratio applies to loans granted by or guaranteed by entities in these jurisdictions; and • deductibility restrictions – expenses paid to such entities may be disallowed unless the taxpayer demonstrates the identity of the ultimate beneficial owner and the operational substance of the foreign entity. Additional Compliance Requirements Brazilian taxpayers must provide enhanced docu - mentation to substantiate the economic substance and legitimacy of transactions involving blacklisted or privileged regimes. Failure to do so may result in denial of deductions, tax reassessments and aggra - vated penalties.
