A foreign buyer enters exclusive negotiations with an Argentine manufacturing group. Financial projections look strong. The seller's management presents clean audited accounts. Then legal due diligence begins. and within two weeks, the review team surfaces undisclosed labour contingencies, an informal foreign exchange arrangement that predates current regulations, and a corporate structure whose shareholding chain is poorly documented. The deal does not collapse, but the purchase price falls significantly and the closing timeline shifts by three months. Scenarios like this are not unusual in Argentina. They are, however, largely avoidable with a well-structured due diligence process.
M&A due diligence in Argentina is a multi-stream legal review covering corporate structure, tax compliance, labour obligations, regulatory status, and foreign exchange exposure of the target company. A properly scoped review typically takes between four and ten weeks and requires documentary analysis under Argentine corporate legislation, tax legislation, labour law, and the civil and commercial code. The primary output is a due diligence report that informs the representations and warranties in the contrato de compraventa de acciones (share purchase agreement, or SPA) and shapes the closing conditions negotiated between the parties.
This guide walks through the full due diligence process for foreign acquirers in Argentina: the preparatory steps, each review stream. Documentary requirements, common errors. Additionally, the decision checklist that helps buyers decide when they have enough information to proceed.
Why Argentine due diligence demands a structured approach
Argentina's legal and regulatory environment creates layers of complexity that do not appear in comparable transactions in Western Europe or North America. Foreign acquirers who apply a standard due diligence template from another jurisdiction frequently miss the most consequential risks.
Argentine corporate legislation – centred on the Ley General de Sociedades (General Corporations Law) – governs the internal affairs of Argentine companies. However, compliance with that legislation is only one part of the picture. The interaction between corporate law, tax legislation, foreign exchange regulations, and labour law creates an environment where a company can be formally compliant in one area while carrying significant undisclosed exposure in another.
Foreign exchange controls are a persistent feature of the Argentine business environment. The Banco Central de la República Argentina (Central Bank of Argentina, or BCRA) administers a system of restrictions on the purchase of foreign currency and the repatriation of profits. Targets with cross-border supply chains, dollar-denominated contracts, or foreign shareholders frequently carry foreign exchange exposure that is not visible in the profit and loss account. A buyer who does not examine BCRA filings and historical currency transactions may inherit compliance obligations or enforcement risk.
Argentine tax legislation adds a further dimension. The federal tax authority, the Administración Federal de Ingresos Públicos (Federal Administration of Public Revenue, or AFIP), operates an active audit programme. Tax assessments can be challenged before administrative tribunals and, ultimately, before the federal courts. The prescription period for tax claims is longer in Argentina than in most OECD jurisdictions. This means that historical tax positions remain open for review well beyond what foreign buyers typically assume. A due diligence that examines only the most recent two or three fiscal years may leave substantial tail risk undiscovered.
Labour law risk deserves equal attention. Argentine employment legislation is strongly protective of employees. Collective bargaining agreements, called convenios colectivos de trabajo (collective labour agreements). Set minimum conditions by industry sector and are binding on all employers in that sector regardless of whether the company is a party to the agreement. Underpayments, misclassified contractors, and unrecorded severance accruals frequently surface during labour due diligence. These are among the most common causes of post-closing disputes in Argentine transactions.

Step-by-step: the due diligence process from preparation to report
A well-organised due diligence process in Argentina follows a sequence of distinct phases. Each phase has defined inputs, outputs, and decision points. Compressing or skipping phases is the single most common mistake made by foreign buyers operating under timeline pressure.
Phase 1 – Scope definition and data room setup (days 1–5). The buyer's legal counsel defines the scope of review by reference to the transaction structure. A share purchase carries different due diligence priorities from an asset acquisition. In a share purchase, the buyer inherits all historical liabilities of the target entity. In an asset acquisition, liability exposure is generally more limited – but regulatory approvals and contract novation requirements can extend the closing timeline considerably. Once scope is agreed, the seller is asked to populate a virtual data room with documents organised by review stream.
Phase 2 – Corporate and title review (days 3–12). This stream examines the target's corporate structure from incorporation to the present day. Reviewers look at the estatuto social (corporate charter), books of shareholders' meetings, share registry, and any pledge or encumbrance over shares. A common problem at this stage is an incomplete or outdated share registry. Under Argentine corporate legislation, share transfers must be recorded in the target's own books to be effective against third parties. Buyers should not assume that the seller's representations about ownership are accurate without verifying the registry directly.
If the target is part of a corporate group, the reviewer maps the entire shareholding chain. Foreign holding entities at the top of the structure may be subject to their own disclosure obligations under Argentine corporate legislation if they conduct activities in Argentina. Unregistered foreign entities operating in Argentina – even as holding companies – can face civil liability limitations that affect the validity of transaction documents.
Phase 3 – Tax review (days 5–18). Tax due diligence in Argentina covers federal income tax, value added tax. Turnover tax levied by each province where the target operates. Additionally, any transaction taxes applicable to the share transfer itself. Argentine tax legislation imposes transfer pricing rules on transactions between related parties. Targets with cross-border intercompany arrangements should be reviewed against AFIP's transfer pricing guidelines, which follow OECD principles but are administered with considerable local discretion.
Tax reviewers request the last five to six years of filed returns, AFIP correspondence, and any ongoing or resolved audits. The longer prescription period under Argentine tax legislation means that assessments from earlier periods can still be raised. Buyers should ask the seller to provide a specific representation on the absence of pending AFIP investigations or, where investigations exist, to quantify the exposure for indemnity purposes.
Phase 4 – Labour and employment review (days 5–15). This stream reviews the target's employee headcount, payroll records, employment contracts, collective bargaining agreement applicability, and accrued severance obligations. Argentine employment legislation provides for statutory severance calculated by reference to tenure and salary. Targets that have undergone restructurings, workforce reductions, or informal employment arrangements carry elevated labour risk. Misclassified contractors are a particular concern: Argentine courts frequently reclassify service relationships as employment relationships, triggering retroactive social security contributions and severance liability.
Phase 5 – Regulatory and sector-specific review (days 8–20). Regulated industries – financial services, energy, telecommunications, food production, healthcare, and media – require a dedicated regulatory stream. Each sector has its own supervisory body and its own compliance obligations. Change of control in a regulated entity typically requires prior approval from the sector regulator. That approval process can take from several weeks to several months, depending on the regulator and the completeness of the application. Buyers who do not identify regulatory approval requirements early in the process routinely find that their anticipated closing timeline is unachievable.
Phase 6 – Environmental review (days 8–18). For industrial, agricultural, or real estate targets, environmental due diligence is a separate stream. Argentine environmental legislation assigns strict liability for remediation of contaminated sites. Buyers of companies with manufacturing facilities, waste handling operations, or agricultural land should commission an environmental review as a condition of any binding commitment.
Phase 7 – Report drafting and risk assessment (days 15–25). The due diligence report consolidates findings across all streams. It identifies confirmed risks, contingent risks, and areas where further information is needed. The report directly informs the SPA negotiation. Confirmed risks typically result in price adjustments, escrow arrangements, or specific indemnities. Contingent risks are addressed through representations and warranties. Areas of incomplete disclosure become conditions precedent to closing.

Documentary checklist: what to request and why it matters
The data room request list is the practical instrument that drives the due diligence process. A poorly drafted request list results in incomplete disclosure, delayed review, and gaps that only appear at closing. The following checklist covers the core documents required across all review streams in an Argentine transaction.
Corporate documents. Request the target's current estatuto social with all amendments, the certificate of incorporation, the share registry book. Books of minutes of shareholders' meetings and board meetings for the past five years. Additionally, any shareholders' agreement or voting trust arrangement. Also request evidence of any pledge, lien, or third-party right over shares.
Regulatory registrations. Request proof of registration with the Inspección General de Justicia (General Directorate of Companies, or IGJ) if the target is incorporated in the City of Buenos Aires, or with the equivalent provincial registry. Request AFIP tax identification documents and, where applicable, registrations with sector regulators.
Tax documents. Request filed returns for income tax, VAT, and provincial turnover tax for the past five to six years. Request any AFIP audit correspondence, tax payment schedules, and instalment agreements. Request transfer pricing documentation for any period in which intercompany transactions occurred.
Labour documents. Request a full list of employees with employment start dates, salary details, and collective bargaining agreement coverage. Request payroll tax filings with AFIP and the social security authority. Request any pending or resolved labour claims, conciliation proceedings, and collective dispute records.
Material contracts. Request all contracts above a defined threshold value, including supply agreements, distribution agreements, technology licences, real property leases, and financing arrangements. Pay particular attention to change-of-control clauses. A significant number of Argentine commercial contracts include provisions that allow counterparties to terminate or renegotiate upon a change of ownership.
Litigation and claims. Request a full list of pending legal proceedings, administrative claims, and arbitration proceedings involving the target as either claimant or respondent. Request the target's external legal counsel to confirm the completeness of that list and to provide their assessment of exposure for each matter.
Foreign exchange and BCRA compliance. Request all filings with the BCRA relating to foreign currency purchases, profit remittances, and intercompany loan registrations. For targets with foreign shareholders, verify that all dividend remittances were made in accordance with applicable BCRA regulations at the relevant time.
Intellectual property. Request certificates of registration for all trademarks, patents, and domain names used in the business. Verify that registrations are held in the target entity's name and are not subject to challenge. Argentine intellectual property legislation requires active use of registered trademarks; non-use for a sustained period can expose registrations to cancellation proceedings.
For buyers who also need to assess the corporate governance structure of the Argentine target as a standalone matter. Our overview of corporate law in Argentina provides relevant background on company types, governance obligations, and registration requirements.
Common errors by foreign acquirers – and how to avoid them
Foreign buyers consistently repeat a set of identifiable errors when conducting due diligence in Argentina. Understanding these errors in advance allows a buyer to design a process that avoids them.
Relying on seller representations without independent verification. Argentine transaction practice does not impose the same documentary disclosure obligations that apply in some common law jurisdictions. Sellers provide representations and warranties in the SPA, but those representations are only as valuable as the indemnity backing them. A buyer who relies primarily on seller representations – rather than independent documentary review – may discover that the indemnity is effectively unenforceable against an offshore holding company after closing. Independent verification through the data room is the only reliable protection.
Underestimating provincial tax exposure. Foreign buyers frequently focus their tax review on federal taxes and treat provincial turnover tax as a secondary concern. In practice, a company operating across multiple Argentine provinces can carry substantial provincial tax arrears. Each provincial tax authority administers its own audit programme and its own prescription periods. A buyer who limits tax due diligence to AFIP filings may close the transaction with undisclosed provincial tax exposure that only materialises during a post-closing audit.
Accepting informal workforce arrangements at face value. Some Argentine companies. particularly family-owned businesses and targets in sectors with high labour informality. carry a portion of their workforce on terms that do not conform to Argentine employment legislation. Management may characterise these workers as independent contractors, commission agents, or service providers. Argentine courts apply substance-over-form analysis to employment relationships. If the working relationship has the characteristics of employment, the courts will treat it as employment regardless of the contractual label. A buyer who acquires a company with a significant informal workforce should price that exposure into the transaction or require pre-closing regularisation.
Treating the closing conditions lightly. Closing conditions in an Argentine SPA. including regulatory approvals, absence of material adverse change, and third-party consents – are sometimes treated as formalities by buyers eager to conclude the deal. In practice, the absence of a required regulatory approval can render a share transfer voidable. An improperly documented change-of-control consent can give a key commercial counterparty grounds to exit a material contract. Buyers should treat closing conditions as substantive requirements, not administrative steps.
Applying insufficient time to the process. Timeline pressure is the most consistent driver of due diligence failure in Argentine transactions. Buyers who compress the review to meet an arbitrary signing deadline routinely discover post-closing that the process did not surface risks that a properly scoped review would have identified. A due diligence timeline of less than four weeks for any transaction of meaningful size should be treated as a warning sign rather than an efficiency gain.
Self-assessment checklist before proceeding to signing
This checklist helps a foreign buyer determine whether due diligence is sufficiently complete to proceed to SPA negotiation and signing.
Corporate and title review is complete if:
- The share registry confirms the seller's ownership free of encumbrances
- The corporate charter and all amendments are consistent with the transaction structure
- All shareholders' meeting resolutions required to authorise the transaction have been identified
- No unregistered or improperly registered foreign holding entities have been identified
Tax review is complete if:
- Filed returns for the relevant prescription period have been reviewed across all applicable taxes
- AFIP audit status has been confirmed and any open audits have been quantified
- Provincial turnover tax exposure across all operating provinces has been assessed
- Transfer pricing documentation is available and consistent with filed returns
Labour review is complete if:
- The full employee population is documented and aligned with AFIP social security filings
- Applicable collective bargaining agreements have been identified and compliance verified
- All contractor arrangements have been reviewed for reclassification risk
- Accrued severance obligations have been independently calculated
Regulatory review is complete if:
- All required change-of-control approvals have been identified and timeline assessed
- All material contracts have been reviewed for change-of-control clauses
- BCRA compliance history has been confirmed and any open foreign exchange positions quantified
The deal should not proceed to signing if any of the following remain open:
- Title to shares has not been independently verified in the share registry
- A regulatory approval has been identified but its timeline or likelihood is unknown
- Material labour or tax contingencies have been identified but not quantified or allocated

Frequently asked questions
Q: How long does M&A due diligence take in Argentina?
A: A standard due diligence process in Argentina typically runs between four and ten weeks, depending on the size of the target and the depth of review required. Regulated industries and companies with foreign exchange exposure often add two to four weeks to that timeline. Delays in document delivery by the seller are the most common cause of extended processes.
Q: What is the biggest misconception foreign buyers have about due diligence in Argentina?
A: Many foreign acquirers assume that a clean set of audited financial statements means the corporate and tax positions are equally sound. In Argentina, financial reporting and legal compliance are frequently misaligned. Tax exposure, undisclosed labour contingencies, and informal foreign exchange arrangements can sit entirely outside the audited accounts and only surface during legal due diligence.
Q: What costs should a foreign buyer expect for legal due diligence in Argentina?
A: Legal fees for due diligence in Argentina vary considerably based on transaction size and scope. A focused review of a small to mid-size target typically starts in the low tens of thousands of US dollars. Comprehensive reviews of larger or regulated targets – covering corporate, tax, labour, environmental, and regulatory streams – can reach into the hundreds of thousands. Buyers should also budget for translation costs and notarisation fees where documents must be submitted to foreign registries.
