Argentina Beneficial Ownership in 2026: The 10% Rule, ARCA and the Provincial Registries
Argentina runs one of the lowest beneficial-ownership thresholds in the world — 10% of capital or votes, set by the financial intelligence unit in 2021 — and has no register anyone can search. The data exists in triplicate: every company declares its shareholders and beneficiario final annually to the tax agency, now called ARCA; sworn beneficial-owner declarations sit with the IGJ in Buenos Aires and its counterparts in every province; and the banks and gatekeepers supervised by the UIF hold their own files at the same 10% line. All of it is sealed — by tax secrecy, by registry practice, by AML confidentiality. Add a federal structure in which each of two dozen jurisdictions keeps its own commercial registry, and Argentina becomes the corpus's clearest case of a country that knows its owners thoroughly and shares nothing: the verifier's route runs through the Boletín Oficial, the provincial registries, and the counterparty's own filings. This guide maps the regime as it stands after the October 2024 FATF evaluation and the AFIP-to-ARCA handover.
01The 10% rule
The operative definition sits in UIF Resolución 112/2021 (Boletín Oficial, 21 October 2021): the beneficiario final is any natural person holding at least 10% of the capital or voting rights of a legal person, trust (fideicomiso), investment fund, or any other legal structure — or who exercises final control, direct or indirect, by any other means. The threshold was halved from 20%, and where no one qualifies, the fallback names the person in charge of the entity's direction, administration or representation. The definition radiates outward: the IGJ, the CNV, the BCRA and the other regulators are themselves obliged subjects before the UIF, so their own rulebooks — and the provinces' — carry the same test.
Calibrate expectations accordingly: an Argentine beneficial-owner list should run long. A structure that yields one name under a 25% regime can yield five or six under 10% — and a short list on a layered structure is, as everywhere in this series, a finding.
02The collection engine: RG 4697 and ARCA
The systematic collection runs through the tax agency. General Resolution 4697/2020 (Boletín Oficial, 15 April 2020, replacing RG 3293/2012) obliges Argentine legal persons — and resident individuals with foreign holdings — to file an annual information return reporting, as at 31 December: their shareholders and members; their beneficiario final, with the supporting chain documented where the ownership is indirect; their directors, managers, síndicos and ARCA-empowered attorneys; and, where relevant, foreign passive entities under the registry created by Law 27.260. Title II registers transfers of participations; Title III keeps corporate authorities current. Since the 2024 dissolution of AFIP, the regime is administered by its successor, ARCA — the Agencia de Recaudación y Control Aduanero — through the same online services.
Two refinements matter. RG 5338/2023 added a listed-entity rule: a resident holding shares in a listed foreign company is its beneficiario final only from 2% of the equity — a strikingly low line that sweeps portfolio-scale positions into the regime. And the sanction structure is the familiar tax-procedure one: automatic and material fines under Law 11.683 for omitted or defective informative returns, plus the practical consequences of bad standing with the agency. The amounts are indexed — check the current schedule rather than quoting a figure.
03Access: sealed three ways
None of this is readable. The ARCA filings sit behind tax secrecy under Article 101 of Law 11.683 — the same seal as Turkey's Article 5 and the LatAm tax-custodian regimes. The sworn beneficial-owner declarations filed with the IGJ — a duty carried through the IGJ's successive general resolutions — and the provincial registries are held by the registrars, not published. And the UIF-side files are AML-confidential by definition — a ring that extends beyond banks to escribanos (the notaries who intervene in Argentine corporate life), accountants and the registrars themselves, each an obliged subject holding its own beneficial-owner file. Argentina has no public or legitimate-interest access route to beneficial-ownership data; the FATF's October 2024 evaluation of Argentina — which the country passed without grey-listing — recorded beneficial-ownership transparency among the areas to keep strengthening, and no centralised public register has been created since. Internationally, the same data moves: Argentina exchanges financial-account information under the OECD Common Reporting Standard and a FATCA agreement with the United States — sealed domestically, shared state to state.
04The public layer: a federal mosaic
Argentina is a federation, and the commercial registry is provincial. The IGJ covers only the City of Buenos Aires; each province runs its own Registro Público (Córdoba, Santa Fe, Mendoza and the rest), with its own procedures, fees and — in several cases — online lookups of varying depth. What binds them is publication: constitutions, capital changes and authority appointments of SAs and SRLs are announced in the Boletín Oficial (national, for CABA) or the provincial gazettes — and for an SRL, whose members appear in the registered contract and its amendments, the gazette trail tracks ownership. For an SA, shares move by private transfer recorded in the company's own share register (and, since 2019's Law 27.444 simplifications, largely outside public filings): the public record freezes at formation — the same cliff this series has mapped from Brazil's CNPJ regime to Mexico's beneficiario controlador. Listed companies are the exception, disclosed through the CNV and BYMA.
One registrable trace softens the SA's darkness — and verifiers routinely miss it. Under the General Companies Law (Ley 19.550), a foreign company that takes shares in an Argentine company must itself register with the local registry (Article 123), appointing a representative and keeping the registration current — with annual informative duties on the IGJ side. So while the transfer of SA shares to a foreign holding goes unpublished, the foreign holding's own presence is on the public record: finding an Art. 123 registration tells you a foreign shareholder layer exists, names its home jurisdiction, and gives you the thread to pull in that country's register. Argentina also settled one question decades ago that still plagues other jurisdictions in this series: bearer shares were abolished — shares must be nominative under Law 24.587 (1995), so ownership is always somewhere on a ledger, even when that ledger is private.
Twenty-four registries, one sealed layer — one workflow
Argentine verification means a provincial-registry mosaic below and sealed beneficial-ownership filings above. Zavia.ai connects directly to official registries in 100+ countries, assembles the Argentine corporate layer — entity, authorities, gazette record — flags where SA ownership cannot be trusted for currency, resolves the chain through the Uruguayan, Spanish, US and other layers where Argentine structures run, and returns an auditable map to the natural person with sanctions and PEP overlays — the benchmark for the RG 4697 filing and the sworn IGJ declaration you request from the counterparty.
05Where to look: free, paid, and sealed
| Source | What it gives you | Cost | Access notes |
|---|---|---|---|
| Boletín Oficial (boletinoficial.gob.ar) | SA/SRL constitutions, capital changes, authority appointments — CABA and national notices | Free | Searchable archive; provincial gazettes separate |
| IGJ (CABA) | Registry records, certificates (informes) on entities and authorities | Small fees per report | Online requests; sworn BF declarations held, not published |
| Provincial Registros Públicos | The same, province by province | Varies by province | Procedures and online depth differ widely — know the jurisdiction |
| CNV / BYMA (listed tier) | Issuers' shareholding and governance disclosures, financials | Free | The glass tier; Spanish, some English |
| ARCA constancia de inscripción | Tax-registration status of a CUIT | Free | Status only — not ownership |
| ARCA RG 4697 filings | Shareholders, beneficiario final, authorities, as at each 31 Dec | Not available at any price | Tax secrecy, Art. 101 Law 11.683 — request via the counterparty |
| IGJ / provincial sworn BF declarations | Declared beneficial owners at 10% | Not public | Registrar-held; via the counterparty |
| SA share register (libro de registro de acciones) | Ownership as it actually stands | Not public | Company book — via the counterparty, reconciled to financials |
06API access and bulk data: what exists, what doesn't
The machine-access position, plainly: no Argentine official source offers a public API or licenses bulk downloads of the corporate register. The Boletín Oficial is a human-readable archive; the IGJ and provincial registries work request-by-request; ARCA's services are taxpayer-credentialed; and nothing at the beneficial-ownership layer is licensable at all — the RG 4697 filings and the sworn declarations are sealed by law. Zavia.ai's delivery model is the answer to exactly this shape: the same official-registry data, retrieved at source and structured, via API, as licensed bulk data feeds, through the online platform, and inside AI agents over MCP — with the sealed layers staying sealed, and the open layer made machine-usable with cross-border chain resolution on top.
| Dimension | IGJ & provincial Registros Públicos | ARCA RG 4697 regime | Zavia.ai |
|---|---|---|---|
| Operated by | The City of Buenos Aires (IGJ) and each province | ARCA — the federal tax agency, successor to AFIP | Zavia.ai — sourced directly from official registries, not third-party aggregation |
| Who can use it | Anyone, per-request; gazette layer free | The tax administration and authorities — sealed by Art. 101 | Any compliance, data or product team, anywhere |
| Entity existence & authorities | Yes — records and paid informes | Not its purpose | Yes — structured, with authorities cross-linked across entities |
| Shareholders | SRL members via registered contracts; SA shareholders generally not after formation | Reported annually as at 31 Dec — sealed | Yes where the source discloses — SA staleness flagged; chains resolved through corporate holders |
| Beneficial owners | Sworn declarations held, not published | Reported annually with chain documentation — sealed | Ownership chain mapped from official registry data through foreign layers to the natural person; the counterparty's filings benchmarked, not replaced |
| Threshold logic | UIF-aligned 10% | UIF-aligned 10%; 2% for listed foreign entities | Configurable to your policy across every jurisdiction |
| Cross-border resolution | One province at a time; Argentine entities only | Argentine taxpayers only | 100+ countries in one query — the Uruguayan, Spanish and US layers above Argentine groups included |
| Freshness | Gazette current for SRL; frozen at formation for SA ownership | Annual, as at 31 December | Real-time updates from official registries, with change monitoring |
| Screening | None | None | Sanctions and PEP overlays on resolved individuals |
| Cost | Free gazettes; small per-report fees | No route at any price for private parties | Subscription — self-serve from $49/month; enterprise licensing for API and bulk |
| Delivery | Manual, per-registry | — | API, bulk data feeds, online platform, MCP integration for AI agents |
07The entity landscape
| Vehicle | Form | Where ownership sits |
|---|---|---|
| Sociedad Anónima | SA | Share register kept by the company; transfers private — the dark form |
| Sociedad de Responsabilidad Limitada | SRL | Members in the registered contract and amendments — the gazette trail stays current |
| Sociedad por Acciones Simplificada | SAS | The digital-first form of Law 27.349 (2017) — restricted in CABA for a period, revived post-2024; registry treatment varies by jurisdiction |
| Listed SA | CNV / BYMA | Disclosure through the regulator and exchange — the glass tier |
| Fideicomiso | Trust under the Civil & Commercial Code | No registry of its own in most cases; parties reported to ARCA and identified at 10% under the UIF test |
08A worked example
Take a Córdoba agribusiness SA, held 60% by a Uruguayan holding company and 40% by three siblings directly. The provincial registry and gazette give you the constitution, the current directors and the founding shareholders — from 2011. The Uruguayan layer bought in later; the transfer itself was never published — but the Uruguayan company's Article 123 registration with the provincial registry marks its presence, and names its home jurisdiction.
Run the regime. Each sibling at 13.3% crosses the 10% line; so does whoever stands behind the Uruguayan company at roughly 17% or more of it — the stake that works out to 10% of the Argentine entity looked through. The company's RG 4697 filing — due annually, as at 31 December — names all of them, with the Uruguayan chain documented; its sworn declaration sits with the provincial registrar. You can read neither. So: pull the registry record and gazette trail; treat the SA shareholder picture as historical; request the share register, the latest RG 4697 acknowledgement and the sworn BF declaration through the counterparty; resolve the Uruguayan layer under Uruguay's own rules — and if the chain runs on to a Panamanian vehicle, under Panama's; and screen the individuals. A filing that names only a director under the fallback, for a structure like this, is a finding.
09Common failure modes
| The mistake | Why it fails |
|---|---|
| Applying 25% — or the old 20% | The UIF halved the threshold to 10% in 2021; every regulator's rulebook follows it |
| Searching for a national registry | The commercial registry is provincial — IGJ is CABA only; know the jurisdiction first |
| Reading gazette shareholders as current for an SA | SA transfers are private ledger entries; the public record freezes at formation |
| Expecting to read the ARCA filings | Tax secrecy under Art. 101 of Law 11.683 seals them absolutely |
| Stopping at a fideicomiso | The parties are identified at 10% and reported — ask the fiduciario, don't assume opacity |
| Missing the 2% listed-foreign rule | RG 5338/2023 sweeps 2%+ holdings in listed foreign entities into the regime |
| Missing the Article 123 trace | A foreign company holding Argentine shares must register locally — its presence and home jurisdiction are public even when the share transfer is not |
| Ignoring the regional superstructure | Uruguayan and Spanish holding layers over Argentine groups resolve in their own registers |
10How to verify an Argentine UBO: workflow
- Fix the jurisdiction. CABA (IGJ) or which province — the registry, fees and procedures follow from it.
- Pull the registry and gazette record. Constitution, authorities, capital events; the Boletín Oficial or provincial gazette for the announcement trail.
- Classify the form. SRL (contract trail current), SA (ownership frozen publicly — ledger via counterparty), SAS (check the jurisdiction's treatment), listed (CNV/BYMA).
- Apply the 10% test. Capital or votes, direct or indirect, then control by other means, then the direction/administration fallback — consciously.
- Request the filings. The share register, the latest RG 4697 acknowledgement and the sworn beneficial-owner declaration, through the counterparty; check the 31 December reference date against known events.
- Resolve the layers above. Uruguayan, Spanish, US and offshore layers in their own jurisdictions.
- Screen and evidence. Sanctions, PEP and adverse-media checks on every resolved individual, with an auditable trail.
11Practical takeaways
| Scenario | What you can rely on | What you must supplement |
|---|---|---|
| Any Argentine company | An RG 4697 filing and a sworn BF declaration must exist | Independent chain-building; both are self-declared and sealed |
| SRL | A current registered-contract ownership trail | The beneficial layer above corporate members |
| SA | Existence, authorities, founding structure | The share register — via the counterparty; treat public ownership as stale |
| Fideicomiso in the chain | Parties identified at 10% and reported | The fiduciario's records, via the counterparty |
Argentina rewards the verifier who takes the threshold seriously and the federation literally. The 10% line — among the lowest anywhere — means Argentine lists run long, and the tax-custodian design means they are refreshed every year and readable never. The public mosaic is genuinely useful for SRLs and the listed tier, historical for SAs, and different in every province. Build the workflow on the jurisdiction, the gazette, the form, the counterparty's own filings and the regional superstructure — and read the October 2024 evaluation for what it was: a pass, with beneficial-ownership transparency still on the to-do list, and no public register on the horizon.

12Frequently asked questions
Does Argentina have a beneficial ownership register?
No searchable register exists. Beneficial-ownership data is collected three ways: annually through the tax agency ARCA under General Resolution 4697/2020, which requires every Argentine legal person to report its shareholders, beneficiario final and corporate authorities as at 31 December; through sworn beneficial-owner declarations filed with the IGJ in Buenos Aires and the provincial public registries; and through the customer-due-diligence files of banks and other obliged subjects supervised by the UIF. All three layers are confidential — tax secrecy, registrar practice and AML confidentiality respectively — and no public or legitimate-interest access route exists.
What is the beneficial ownership threshold in Argentina?
10% — among the lowest in the world. UIF Resolución 112/2021 defines the beneficiario final as any natural person holding at least 10% of the capital or voting rights of a legal person, fideicomiso, investment fund or other legal structure, or who exercises final control by any other means; the previous threshold of 20% was halved. Where no natural person qualifies, the person in charge of the entity's direction, administration or representation is treated as the beneficiario final. Because the IGJ, CNV, BCRA and provincial registries are themselves obliged subjects before the UIF, the 10% test runs through their rulebooks too.
What is the RG 4697 information regime?
The annual collection engine, administered since 2024 by ARCA (formerly AFIP). General Resolution 4697/2020 obliges Argentine legal persons — and resident individuals with foreign participations — to file an annual return reporting, as at 31 December each year: shareholders and members; the beneficiario final, with the chain of intermediate holdings documented where ownership is indirect; directors, managers, síndicos and empowered attorneys; and foreign passive entities under the registry created by Law 27.260. Separate titles register transfers of participations and keep corporate-authority data current. Filing runs through ARCA's online participaciones societarias service.
Who is the beneficial owner if no one holds 10%?
The test continues to control by other means: any natural person exercising final control of the entity, directly or indirectly, through the chain of ownership or otherwise, qualifies regardless of percentage. Only where no one can be identified on either basis does the fallback apply: the natural person in charge of the entity's direction, administration or representation is recorded as the beneficiario final. As in the other cascade regimes in this series, a filing that names only a director or administrator for a structure with concentrated ownership above it deserves scrutiny — it usually means the earlier steps were cut short.
Is Argentina on the FATF grey list?
No. Argentina's fourth-round mutual evaluation, conducted with GAFILAT and discussed at the FATF's October 2024 plenary, did not result in grey-listing — an outcome the country had worked toward with the March 2024 reform of its AML law (Law 27.739) and related measures. The evaluation nonetheless identified beneficial-ownership transparency among the areas requiring continued strengthening, and Argentina reports progress through the standard follow-up process. No centralised or public beneficial-ownership register has been created since the evaluation.
Can I see the shareholders of an Argentine company?
It depends on the form and the province. An SRL's members appear in its registered contract and amendments, announced through the Boletín Oficial or the provincial gazette, so the public trail tracks ownership. An SA's shares transfer privately in the company's own share register, so the public record generally freezes at formation — current ownership comes from the ledger, via the counterparty. Listed companies disclose through the CNV and BYMA. And because the commercial registry is provincial, what is retrievable online, at what fee, differs between the IGJ in Buenos Aires and each province's Registro Público.
How are trusts (fideicomisos) treated?
The fideicomiso — the Civil and Commercial Code trust used across Argentine real estate, finance and agriculture — is squarely inside the regime. The UIF's 10% definition applies to fideicomisos expressly: the fiduciante, fiduciario, beneficiaries and any controller are identified under the same test, and obliged subjects must identify the beneficial owners of each party to the contract. The tax-side information regimes require trust reporting to ARCA, and the RG 4697 chain-documentation duty runs through trust layers like any other. Verification routes through the fiduciario — a regulated party in financial fideicomisos — and the counterparty's filings.
What is the 2% rule for listed foreign entities?
An amendment by General Resolution 5338/2023 to the RG 4697 regime: where an Argentine-resident individual holds shares in a foreign entity that publicly lists its securities, the resident is treated as its beneficiario final for reporting purposes from just 2% of the shareholding — or, failing that, where they exercise final control by other means. The unusually low line sweeps portfolio-scale foreign positions into the annual information return. It is a reporting threshold for residents' foreign holdings, not a change to the domestic 10% beneficial-owner definition.
What replaced AFIP?
ARCA — the Agencia de Recaudación y Control Aduanero — created in late 2024 when the federal government dissolved AFIP and reorganised its tax and customs functions into the new agency. For beneficial-ownership purposes nothing substantive changed: the RG 4697 information regime, the participaciones societarias online service, the tax-secrecy protection of Article 101 of Law 11.683 and the sanction framework all continue under ARCA's administration. Filings, acknowledgements and taxpayer services now run under the ARCA name, and references to AFIP in older guidance should be read accordingly.
How do you verify the ownership of an Argentine company?
Fix the jurisdiction first — IGJ for Buenos Aires City, otherwise the relevant provincial Registro Público — and pull the registry record and gazette trail: constitution, authorities, capital events. Classify the form: SRL contract trails stay current; unlisted SA ownership freezes publicly at formation, so request the share register; listed names disclose via CNV. Apply the 10% test with its control limb and fallback, request the latest RG 4697 acknowledgement and the sworn beneficial-owner declaration through the counterparty, check the 31 December reference date, resolve Uruguayan, Spanish and other foreign layers in their own registers, and screen every individual identified with an auditable trail.
