In the Peruvian competitive business environment, tax audits in Peru have become fundamental for organizations aiming to maintain strict tax compliance while optimizing tax payments. Frequent updates to the SUNAT (Superintendencia Nacional de Aduanas y de Administración Tributaria – National Superintendency of Customs and Tax Administration) regulations and the application of International Auditing Standards (IAS) and International Financial Reporting Standards (IFRS) make it essential to have specialized audit services that guarantee transparency, efficiency, and financial security.
What Is Tax Auditing in Peru?
A tax audit involves a comprehensive analysis of a company’s tax situation to verify the correct declaration and tax payment to the SUNAT, detect inconsistencies, errors, or omissions that could result in penalties or fines, and also identify legal opportunities to optimize the tax burden.
Unlike a financial audit in Peru, which aims to validate financial statements in general, a tax audit focuses on tax issues and their correct application within the current legal framework. It is a risk mitigation tool that prevents tax risks and enhances accounting management.
Importance of Tax Audits in Peruvian Companies
Tax compliance in Peru is not only a legal obligation but also a reputational business and sustainability factor. An error in tax returns or in the interpretation of regulations can result in significant penalties, as well as damage the organization’s credibility with partners, customers, and investors.
Tax audits in Peru ensure transparency and financial order through a detailed review of accounting records, monthly and annual returns, and supporting documentation, which allows companies to anticipate possible SUNAT observations and avoid tax contingencies.
Additionally, tax audits are directly related to financial assurance in Peru, since verifying the consistency between accounting and tax information reinforces the reliability of financial statements.
Types of Tax Audits
In practice, tax audits often include other types of reviews that strengthen business management:
- Accounting audit ensures that accounting records are correctly structured and comply with IFRS.
- Internal audit: evaluates internal controls and processes that affect tax management.
- External audit: provides an independent opinion on compliance with tax and accounting obligations.
- Compliance audit: reviews the company’s adherence to current tax and labor legislation.
- Internal control audit: identifies flaws in control systems that could lead to errors in tax returns.
- Audit under SUNAT regulations: ensures that processes are aligned with the tax authority’s requirements.
These reviews provide an overview of the company, strengthening governance and financial compliance at all levels.
Tax Audit by Sector in Peru
Each economic sector has particularities that require specific audit procedures. In Peru, audit services adapt to the needs of different industries:
- Audit for the mining sector: Control of royalties, specific taxes, and export withholdings.
- Audits for the construction sector: Verification of budgets, valuations, and IGV (Impuesto General a las Ventas – General Sales Tax/VAT) payments on construction projects.
- Audits for the retail sector: Review of inventories, e-invoicing, and tax credits.
- Audits for the agro-industrial sector: Control of exports and tax benefits for the agricultural industry.
- Audits for technology companies and startups: Analysis of digital revenues, cloud services, and international withholdings.
- Audits for NGOs and the financial sector: Compliance with specific accounting standards and reviews of donations or funds.
An auditing consultancy in Peru, specialized in each industry, ensures accurate diagnoses and recommendations tailored to the operational context.
Regulatory Compliance and Tax Quality Assurance
Compliance with International Auditing Standards (IAS) and International Financial Reporting Standards (IFRS) is essential to ensure the effectiveness and comparability of accounting and tax reports. An IFRS audit in Peru provides an accurate reflection of the company’s financial position, while an ISA audit establishes the applicable review and assurance methodology.
Locally, a SUNAT audit ensures the correct application of tax regimes—General Regime, MYPE, or Special Income Tax Regime—and consistency in IGV, income, and other tax returns. Moreover, the risk audit identifies possible tax contingencies, and the process audit optimizes the efficiency of tax management.
The result is assurance of tax compliance in Peru, which not only avoids penalties but also contributes to the continuous improvement of the internal financial system.
Benefits of Tax Audits in Peru
Among the main advantages of conducting a tax audit in Peru are:
- Prevention of penalties and fines: Advance review avoids observations or audits with adverse results.
- Tax optimization applies tax benefits, deductions, or credits correctly.
- Financial compliance reinforces transparency and improves strategic decision-making.
- Financial process assurance guarantees the integrity of accounting data.
- Accounting certification: it supports banks, investors, and regulatory bodies.

Additionally, companies conducting periodic audits can access accounting certification and certification services under international standards, strengthening their corporate reputation.

Beyond the cost, an audit is an investment in financial security and business continuity.
