Abstract

The offsetting of withholding income tax (IRRF) on service exports represents a significant challenge in international taxation for Brazilian companies. The diversity of foreign tax systems, the lack of documentary standardization, and the rigorous demands of national legislation make credit recognition difficult. The study aimed to analyze the legal, documentary, and operational challenges related to offsetting the IRRF paid abroad on service exports, considering Brazilian legislation, international treaties, and administrative jurisprudence from CARF. A qualitative, exploratory, and analytical approach was used, through bibliographic review, normative examination, jurisprudence investigation, and a case study in a multinational company. Company X, with service exports of R$ 26,647,021.30 in 2025 to 32 countries, was analyzed. The results indicated that the main obstacles do not lie in the absence of a legal basis, but in the asymmetry between Brazilian formal requirements, such as official documents, sworn translations, and apostilles, and the operational reality of withholdings. This situation generated a negative IRPJ balance of R$ 10,737,400.49 in 2025, evidencing the economic risk of disallowance. It was concluded that effective IRRF offsetting requires structured tax governance, documentary standardization, and integration between the involved units and areas.

1. Introduction

The Brazilian tax system is often described by doctrine as one of the most complex in the world, a result of the overlap of taxes, the multiplicity of legal regimes, and normative instability. This characteristic, as pointed out by Torres (2003), generates a high degree of legal uncertainty and imposes relevant challenges on companies, especially when they are involved in operations that extend beyond national territory.

Regarding the export of services, Withholding Income Tax (IRRF) presents relevant particularities, as its application does not stem exclusively from domestic tax legislation, but also from international treaties signed by Brazil and guidelines formulated by multilateral organizations, especially the Organization for Economic Cooperation and Development (OECD). This normative overlap contributes to the existence of distinct models of tax withholding, certification, and proof in various countries, which frequently generates incompatibilities when confronted with the formal requirements of the Brazilian Federal Revenue Service.

The incidence and subsequent compensation of IRRF on service exports involve two distinct scenarios: intercompany and non-intercompany operations. In intercompany operations, the provision of services occurs between companies belonging to the same economic group, characterized by internal financial flows and, often, by administrative structures that do not fully meet Brazilian requirements for documentary proof. The lack of standardization among subsidiaries, discrepancies in tax records, communication difficulties between foreign units, and distinct accounting practices increase the risk of denial of claimed credits. In non-intercompany operations, in turn, challenges arise related to the heterogeneity of withholding certificates issued by foreign clients, linguistic barriers, differences in tax collection systems, and limitations in the provision of complete information by the contracting parties.

The doctrine of international tax law recognizes the credit for taxes paid abroad as an essential instrument for the elimination of double legal taxation. However, as pointed out by Xavier (2010) and Schoueri (2018), the effectiveness of this mechanism depends on the strict fulfillment of legal, documentary, and procedural requirements, the non-compliance with which is sufficient to make the intended credit unfeasible.

Given this scenario, the offsetting of Withholding Income Tax (IRRF) paid abroad on service exports is frequently limited by operational and documentary obstacles. These challenges represent a significant practical and theoretical gap, as they directly affect the cash flow, tax costs, and fiscal governance of Brazilian companies involved in global service provision chains. Proper management of the offsetting process can substantially improve financial liquidity, reduce tax burdens, and strengthen the fiscal governance of organizations. By critically examining the obstacles faced in the corporate reality and proposing reflections aligned with good tax compliance practices, this research seeks to contribute to the evolution of national literature and offer technical subsidies for strategic decision-making in the business environment. Thus, this work aims to analyze, in an integrated manner, the legal, documentary, and operational challenges related to the offsetting of Withholding Income Tax (IRRF) paid abroad on service exports, encompassing both intercompany and non-intercompany operations, seeking to understand how Brazilian legislation, international norms, and business practices interact and affect the utilization of tax credits, as well as to identify the main factors that contribute to financial losses and disallowance risks.

2. Material and Methods

The development of this study was based on a qualitative approach, of an exploratory and analytical nature, suitable for understanding the legal, documentary, and operational challenges related to the compensation of Withholding Income Tax (IRRF) in the context of service exports. The research adopted as a methodological strategy the integrated analysis of bibliographic review, normative examination, investigation of administrative jurisprudence, and case study, allowing the legal framework to be related to concrete business practices.

Initially, a literature review was conducted focusing on the contextualization of the fundamentals of international taxation. This stage emphasized the criteria of residence and source, the methods for eliminating double taxation provided for in the Model Tax Convention of the Organisation for Economic Co-operation and Development (OECD), and the application of income tax in international operations involving the provision of services. Specialized literature was used as a theoretical basis to identify key concepts and points of convergence between domestic law and international treaties.

Next, the applicable Brazilian legislation was analyzed. Highlighted were Law No. 9.430/1996, Law No. 12.973/2014, the Income Tax Regulation (RIR/2018), and Normative Instruction RFB No. 213/2002. This stage aimed to identify the material and formal requirements for the offset of taxes paid abroad, such as the inclusion of income in the calculation of real profit, legal offset limits, and documentary proof criteria.

Concurrently, an analysis of the administrative jurisprudence of the Administrative Council of Tax Appeals (CARF) was carried out. This investigation was based on representative rulings and consultation solutions on the subject. The jurisprudence was examined based on previously defined analytical categories, which included: (i) the legal limits of the tax credit paid abroad; (ii) the formal requirements for documentary proof; (iii) the timing of credit recognition; and (iv) the main grounds used by the tax administration to disallow the compensation claims.

To verify practical adherence to the legal analysis, a case study was adopted in a large multinational company, hereinafter referred to as Company X. This company has a relevant presence in Brazil and recurrent exposure to service export operations. The choice of Company X was justified by its high participation in intercompany and non-intercompany operations, the diversity of jurisdictions involved, and the recurrence of withholding income tax abroad.

The case study analysis focused on the internal procedures adopted by Company X for the identification, documentation, control, and attempted offset of Withholding Income Tax (IRRF) paid abroad. The following were used as analytical criteria: (i) the adequacy of the received documents to the requirements of Brazilian legislation; (ii) the standardization of documentary flows; (iii) the integration between internal areas and international units; and (iv) the friction points between business practice and the formal rigor required by the Brazilian tax administration.

Data collection involved the examination of fiscal documents, proof of withholding from abroad, internal reports, corporate communications, and IRPJ (Corporate Income Tax) calculation statements. Company X’s anonymity was preserved throughout the process. Data interpretation aimed to identify recurring patterns, operational weaknesses, and determining factors for the risk of disallowance, allowing for the correlation of regulatory and jurisprudential requirements with practical difficulties encountered.

Furthermore, agreements to avoid double taxation entered into between Brazil and other countries were considered as a complementary methodological element, especially those that adopt the credit method for the elimination of double juridical taxation, as provided for in the OECD Model Convention. The analysis of the treaties aimed to verify the material limits of the right to offset taxes paid abroad and to assess whether the restrictions observed in practice arise from conventional clauses or, predominantly, from normative and operational requirements imposed by Brazilian legislation and tax administration.

This methodological approach enabled the construction of a critical and applied analysis on the compensation of IRRF in service exports, integrating theory, legislation, jurisprudence, and business reality. The research sought to provide a comprehensive understanding of the multiple factors that influence the effectiveness of tax compensation in a scenario of international complexity.

3. Results and Discussion

The analysis of the research results revealed that the growth of Company X’s service exports, although strategic for its international expansion and revenue increase, introduced significantly greater tax complexity, especially regarding Withholding Income Tax (IRRF). The company’s expanded global presence was not limited to an increase in operations and financial values, but intensified the fiscal and operational risks inherent in proving taxes paid abroad and subsequently claiming credits in Brazil. This dynamic underscores the need for robust and adaptable tax management.

The findings demonstrated that the diversity of foreign tax regimes, with their specific rules for withholding tax, issuance of receipts, and recognition of taxes paid, exposes the company to a complex scenario. This jurisdictional heterogeneity indicates that the challenge of offsetting withholding income tax is not merely quantitative, but structural. The effectiveness of the offset depends less on the existence of the substantive right to the credit and more on the company’s operational capacity to adequately prove, in accordance with the formal requirements of Brazilian legislation, the effective incidence and payment of the tax abroad, as highlighted by Schoueri (2018).

In this context, the results indicate that the central problem of IRRF (Brazilian withholding income tax) compensation does not predominantly lie in the absence of a legal basis or incompatibility with international double taxation agreements. The main obstacle resides in the asymmetry between the formal requirements of Brazilian legislation and the operational reality of withholdings made by foreign clients and entities. As exports expand, the volume of documents received from abroad increases, frequently presenting heterogeneity in language, format, and certification, raising the risk of credit denial, even when the tax has been effectively collected.

The analysis of Company X’s export revenue in 2025 contextualizes this scenario, with a total international turnover of R$ 26,647,021.30, distributed among 32 countries. This data not only highlights the economic relevance of service exports for the company but also the complexity arising from operating in multiple tax jurisdictions. The dispersion of revenue across various countries, even with individually reduced amounts, imposes a disproportionately greater documentary effort due to the diversity of regulations and the absence of standardization in foreign tax systems.

It was observed that France and Spain concentrated approximately 83% of Company X’s international revenue, which suggests greater legal-tax predictability, given that both countries maintain double taxation agreements with Brazil. In contrast, the distribution of the remaining revenue among other jurisdictions, although with smaller amounts, requires a marked sophistication in fiscal governance mechanisms and documentary control to ensure compliance and the utilization of credits.

The concentration of exports in jurisdictions covered by international agreements, such as France, Spain, Italy, Belgium, Canada, and Japan, which adopt the credit method according to Article 23 of the OECD Model Convention, is not tax-neutral. However, the analyzed data show that the mere existence of these agreements does not eliminate the obstacles to the effective use of tax credits. Difficulties persist related to proving the tax paid abroad and obtaining documents recognized by the foreign tax authority, in accordance with Brazilian formal requirements.

Conversely, exports spread across jurisdictions without a treaty impose a proportionally higher operational cost, as they require a case-by-case analysis of tax incidence and offer less predictability regarding credit recognition. This scenario reinforces that, although international agreements are important for delimiting the right to compensation, the main practical obstacles remain associated with operational and procedural aspects, not the absence of conventional support, demanding continuously updated technical and operational capacity from the company.

It is important to note that not all service exports necessarily result in withholding income tax in the destination country. In several jurisdictions, income taxation may be conditioned on the characterization of a relevant economic presence, the specific nature of the service provided, or the existence of a permanent establishment. This means that, even with international invoicing and exposure to multiple legal systems, the right to offset withholding income tax in Brazil is not always established, reinforcing the need to assess, on a case-by-case basis, the actual tax incidence abroad.

Based on the information extracted from the company’s internal records, it was verified that the Withholding Income Tax (IRRF) levied on international revenue throughout the fiscal year 2025 totaled R$ 1,840,390.98. This amount reflects the incidence of the tax on service export operations carried out during the period, highlighting the financial relevance of the tax credit arising from these operations and the need for efficient tax management for its utilization.

The company adopts a conservative stance regarding the utilization of these credits, opting not to use them immediately, month by month, in its income tax calculation. This strategy stems, above all, from the high volume of transactions carried out with multiple jurisdictions, each subject to its own rules for withholding, documentation, and proof of tax paid abroad. The company prioritizes the use of domestic credits, such as those arising from operations with public bodies or financial investments, which present a lower degree of bureaucracy and greater operational predictability.

In this context, the Withholding Income Tax (IRRF) credit arising from exports remains recorded as an asset for future offsetting, subject to adequate documentary validation and the consolidation of necessary information. The evolution of the accumulated IRRF balance throughout 2025 showed continuous growth, demonstrating that the main challenge associated with exports lies not only in the financial volume of the credit but also in the operational complexity and the level of precision required for its correct utilization before the Brazilian tax administration.

Given this scenario, the accumulation of income tax credits, both domestic and international, resulted in the formation of a negative IRPJ balance at the end of the 2025 fiscal year. The amount of advances exceeded the tax effectively due in the annual calculation of Real Profit, generating a negative IRPJ balance of R$ 10,737,400.49. The recovery of this balance depended on the formal instruments provided for in the legislation, such as PER/DCOMP, used for offsetting with own debts administered by the Federal Revenue of Brazil.

The analysis also showed that income tax credits paid or withheld abroad are subject to restrictions on their use, according to the consolidated understanding of the Administrative Council for Tax Appeals (CARF). CARF’s jurisprudence limits the offset to the amount of tax due in Brazil on the same income, prohibiting its use to form a negative balance eligible for refund. This understanding reinforces the need for strict segregation and control of tax credits, distinguishing those of a domestic nature from those originating abroad.

The IRPJ (Corporate Income Tax) calculation for the fiscal year 2025, which resulted in a negative balance of R$ 10,737,400.49, highlighted the importance of integrated tax compliance and governance management. The amount of IRRF (Withholding Income Tax) on international revenue, which contributed to this negative balance, was R$ 1,840,390.98. Other relevant deductions included IRRF on public entities (-R$ 5,640,205.26), IRRF on private entities (-R$ 10,867,944.96), and IRRF on financial investments (-R$ 808.52), demonstrating the complexity of the offsets.

The audited results show that the risk of disallowance of IRRF credits constitutes not only a legal risk but also a relevant economic risk for the company. The compensation system through PER/DCOMP, provided for in art. 74 of Law No. 9,430/1996 and regulated by Normative Instruction RFB No. 2,055/2021, subjects the taxpayer to a high degree of formalism. Insufficient or inadequate supporting documentation may result in the non-approval of the compensation, with the consequent reestablishment of the tax debt’s enforceability.

From an economic point of view, this scenario implied relevant financial impacts, as amounts previously recognized in assets began to constitute exigible liabilities, subject to the incidence of default charges, in addition to the need for accounting provisioning. Furthermore, the process of responding to tax summons, preparing administrative defenses, and eventually initiating tax litigation generated additional costs with specialized legal advice, allocation of internal teams, and immobilization of financial resources for prolonged periods.

In this context, the risk of disallowance transcended the strictly fiscal sphere, becoming a factor of economic inefficiency, especially in fragmented export operations of lower individual value. The possibility of definitive loss of credit, added to the operational costs of the proof and defense process, showed that the management of IRRF in exports must consider not only the existence of the credit right but also the total economic cost associated with its recovery, under penalty of compromising the overall profitability of international operations.

From a critical perspective, the study’s results highlight a mismatch between the high formal rigor of Brazilian tax legislation and the logic of economic efficiency that guides international service provision operations. Although the legal system theoretically ensures the right to offset taxes paid abroad, the multiplicity of documentary requirements, such as obtaining proof issued by foreign tax authorities, sworn translation, apostille, and administrative validation, imposes significant operational costs and deadlines incompatible with business dynamics.

In the case of Company X, this rigor resulted in the deliberate adoption of a conservative strategy, maintaining withholding tax credits on the asset without immediate use, despite their high financial value, as a way to mitigate the risk of disallowance and tax assessment. This stance, although legally prudent, implies concrete economic inefficiencies, such as the immobilization of resources, increased compliance costs, and reduced expected economic benefit from the internationalization of service operations.

Thus, it is observed that the main obstacle to the compensation of IRRF does not arise from the absence of a legal basis or incompatibility with international treaties, but from the asymmetry between Brazilian administrative formalism and the operational reality of international transactions. This asymmetry compromises tax neutrality and reduces the competitiveness of Brazilian service exports, directly impacting the company’s ability to fully take advantage of the tax benefits provided for in the legislation.

In summary, the research demonstrated that effective compensation of IRRF in service exports requires structured fiscal governance, standardization of documentary flows, integration between national and international units, and constant alignment between the fiscal, legal, and operational areas. The effectiveness of credit rights is conditioned by factors that go beyond the mere existence of a legal basis, demanding robust organizational capacity to consistently and verifiably comply with formal requirements, mitigating the risks of disallowance and financial losses.

4. Conclusion

The present study aimed to analyze the legal, documentary, and operational challenges related to the offsetting of Withholding Income Tax (IRRF) paid abroad on service exports, considering Brazilian legislation, international treaties, and administrative jurisprudence from CARF. It was found that the complexity of IRRF offsetting does not primarily lie in the absence of a legal basis or incompatibility with double taxation agreements, but rather in the asymmetry between the formal requirements of Brazilian legislation and the operational reality of foreign withholdings. A case analysis at Company X, which invoiced R$ 26,647,021.30 for service exports to 32 countries in 2025, showed that the diversity of tax regimes and documentary heterogeneity, even in jurisdictions with treaties, significantly increase the risk of credit disallowance. It was observed that the IRRF levied on international revenue totaled R$ 1,840,390.98, contributing to a negative Corporate Income Tax (IRPJ) balance of R$ 10,737,400.49 at the end of the fiscal year 2025. CARF’s jurisprudence, by limiting the offset to the tax due in Brazil on the same income, prevents the formation of a refundable negative balance, reinforcing the strictly offsetting nature of the credit.

This situation reveals that the risk of disallowance transcends the legal sphere, constituting a substantial economic risk for companies, with costs associated with resource immobilization, compliance, and eventual litigation. The study’s main contribution lies in demonstrating that the effectiveness of withholding tax offset depends on structured fiscal governance, standardization of documentary flows, and continuous integration between the fiscal, legal, and operational areas of organizations. Although the right to offset is assured, the organizational capacity to consistently meet formal requirements is decisive for tax efficiency in international operations. The results offer technical subsidies to improve international tax management, mitigate risks, and strengthen internal controls, contributing to the economic sustainability of global operations. The nature of a single case study, although in-depth, suggests that future investigations could explore the application of these guidelines in a broader universe of companies.
