The chain, in order
Everything in Argentine finance keys off one of two identity numbers, and they key off your immigration status. Work the chain in this order and the process makes sense; attack it from the bank end and it does not.
| Step | What it is | What it needs |
|---|---|---|
| 1. Migration file | An expediente at the immigration directorate, and in practice a residencia precaria once your application is filed | A filed residency application |
| 2. CUIL | The labour identity number issued by the social security agency | A DNI for foreigners — or, without one, any one of three alternatives: a migration file showing your current residence type and your entry to the country; a passport recording a residence type that is not tourist or permanent; or an entry permit issued by a consulate or under an international agreement |
| 3. CUIT | The tax identity number issued by the tax authority | Either a CUIL, or the specific application route for a foreign resident without a DNI |
| 4. The account | A caja de ahorro in pesos, usually with a dollar account alongside | Your identity number, proof of address, and whatever the individual bank asks for |
| 5. CBU and alias | The 22-digit account identifier and its human-readable nickname — the rails everything here runs on | The account |
The link that breaks for most newcomers is step 2 — and it is routinely described wrongly, including by us until we re-read the page. The social security agency’s own page directs the service at Argentines and at foreigners who want to work here in employment. For an applicant without a DNI it asks for one of three documents, not all of them: an expediente de migraciones “donde conste el tipo de residencia vigente y el ingreso al país”; a passport “en el que conste tipo de residencia, la cual no debe ser turista o permanente”; or a “permiso de ingreso al país expedido por Consulados o en virtud de Convenios Internacionales”.
Notice where the tourist exclusion actually sits: in the passport option, not as a blanket rule across all three. The practical reading is still that a visa-free tourist arrival gives you nothing to put in any of the three boxes — there is no migration file, the passport route excludes tourist status in terms, and an ordinary entry stamp is not a consular or treaty entry permit. But the page nowhere says “a tourist cannot get a CUIL”, so neither will we. If your entry was under a consular permit or a bilateral agreement, read the third option again and ask ANSES. Our residency guide is the step before this one.
The CUIT route for a foreign resident without a DNI
The tax authority publishes a specific path, and it is worth knowing because it means you do not have to wait for a DNI to become tax-legible. You file through the digital submissions system, under the “special situations” heading for a new individual CUIT, or in person at an agency.
What it needs, from the tax authority’s own page:
- Form F. 460 F/PD, sections 1 to 5.
- Your identity document or passport.
- A current immigration certificate showing your expediente number and the nature of your residency.
- A clear frontal photograph.
- Proof of address where it differs from the address on file.
The CUIT issued this way is provisional, with a maximum validity of two years, or tied to the admission period immigration granted you. Within ten business days of receiving an Argentine DNI you must apply for the ordinary resident CUIT and request the linking of your credentials and the unification of your historical registry data, on form F. 581/PD.

What about a CDI?
You will read that a non-resident can obtain a CDI — an identification code rather than a tax number — with a passport, and use it to open basic banking. We checked the tax authority’s page on identity numbers for foreigners and it addresses CDI only in the context of diplomatic representations and similar entities; there is no CDI route described there for an ordinary foreign individual. That does not prove the route does not exist, but it does mean we are not going to tell you it does. If it matters to your plan, ask the tax authority directly rather than a blog.
What the account actually gets you
Argentina runs on bank transfer far more than on card. What you are really buying with all this paperwork is a CBU — the 22-digit account identifier — and an alias, its readable nickname. With those you can:
- Pay rent, a coach, a cleaner or a plumber by transferencia, which is how most people here settle most things. Every contact in the ArgExpats directory will quote you a CBU or an alias sooner or later.
- Receive money from abroad through services that pay into a local account. Wise, for example, needs your full name, postal address, 22-digit CBU and 11-digit CUIT or CUIL — and caps transfers into pesos at the equivalent of USD 18,000 per transfer and per calendar month, which is its own platform rule rather than an Argentine one.
- Open an account at a locally registered crypto exchange, which is the route with the best legal rate for converting dollars. Details in our guide to getting paid in USD.
- Hold a dollar account alongside the peso one, which since 2025 is materially more useful than it used to be.
Note that fintech wallets issue a CVU rather than a CBU. Functionally they interoperate for transfers; legally the underlying product is different.
Two rules that make a local account worth having
No commission on incoming foreign currency
BCRA Comunicación “A” 8330, dated 2025-09-18, says banks “no podrán cobrar comisiones” on operations by resident individuals that credit foreign currency from abroad into accounts the client holds in foreign currency. Only documented correspondent-bank charges may be passed through, at cost.
The same communication abolished the USD 36,000 annual cap on receiving service-export income without converting it to pesos, and a further communication in April 2026 extended that to all service concepts. In other words: you can receive dollars, keep them as dollars, in an Argentine bank, without a cap and without a bank commission. That is a genuinely new situation and it is the main reason a local account is worth the paperwork now.
Savings accounts are exempt from the transaction tax
The 0.6% tax on bank debits and credits — the impuesto al cheque — exempts caja de ahorro savings accounts. Receiving into a savings account rather than a current account avoids it. Registered monotributistas have also been able to claim an exemption on current accounts since 2021, but it is not automatic: you have to enrol in the register of fiscal benefits and select the monotributo option.
The reason to be in the banking system at all changed in 2025
For a decade there was a rational argument for staying out of the Argentine banking system: the official exchange rate was rationed and well below the street price, so money that entered through a bank lost a large chunk of its value on arrival. That argument is gone.
Currency controls on individuals were lifted on 2025-04-11, and on 2026-09-13 the parallel rate sat about one percent from the official one. There is no longer a meaningful penalty for bringing money in officially — and there are real benefits to the paper trail, because a lease, a residency renewal and a tax return all want documented income. Our blue dollar guide has the full picture.
It matters for one immigration route in particular: the rentista category requires that the funds enter Argentina through banking or financial institutions authorised by the central bank. The old incentive to route money informally was directly in tension with that requirement. It no longer is.
What we could not verify — and are not going to guess at
This is the section most guides skip, and skipping it is how people end up at a branch with the wrong documents.
- Which banks accept which residency status. Requirements are set bank by bank on top of the central bank’s rules, and we found no authoritative published comparison. Every list of “banks that accept foreigners” we found sits on commercial or search-optimised pages. Call two branches and ask; the answers differ.
- Whether digital banks accept a receipt for an identity application in progress. This is widely reported and would be genuinely useful if true. We could not confirm it from any bank’s own terms.
- Whether a non-resident can open a savings account with a passport alone. A non-resident account modality is described in secondary sources; we could not read the rule ourselves.
- ATM fees and withdrawal limits for foreign cards. The figures in circulation vary so widely — per-operation charges and daily caps differing by an order of magnitude between sources — that publishing any of them would be worse than publishing none.
- Which exchange rate a given remittance service uses for the peso leg. Wise’s own help page does not say. Get a live quote before you commit.
The practical move: before you go to a branch, write down which residency status you actually hold, call and ask what that specific status needs, and take originals of everything.
Commonly repeated, and now wrong
| You will read | The position as of 2026-09-13 |
|---|---|
| “Foreigners cannot open bank accounts in Argentina” | Wrong framing. The constraint is the identity number, which depends on your immigration status — not on your nationality. |
| “Get a CUIL as a tourist” | The social security agency gives an applicant without a DNI three alternative documents, and an ordinary tourist arrival produces none of them: a migration file showing your current residence type, a passport whose recorded residence type “no debe ser turista o permanente”, or a consular or treaty entry permit. The tourist exclusion is written into the passport option specifically. |
| “You must wait for a DNI to get a tax number” | No. There is a documented route to a provisional CUIT for a foreign resident without a DNI, valid up to two years. |
| “Do not put money through a bank, you will lose 40% on the exchange rate” | Dead since April 2025. The gap is roughly one percent, and the paper trail has real value for leases, residency and tax. |
| “Your bank will charge you to receive an international wire” | Prohibited since 2025-09-18 on foreign currency credited to your own foreign-currency account. Correspondent fees en route are separate and real. |
| “You can only receive USD 36,000 a year from abroad” | Cap abolished 2025-09-18. |
| “Every account pays the 0.6% transaction tax” | Savings accounts are exempt, and registered monotributistas can claim an exemption on current accounts — but only if they actively enrol. |
Common questions
Can a foreigner open a bank account in Argentina?
Yes, once you have the identity number Argentine financial products are keyed to. The real constraint is immigration status: you need a migration file and, in practice, a residency application in progress before the chain to a CUIL and a CUIT opens up.
Can a tourist get a CUIL in Argentina?
Not on the documents the social security agency lists. Without a DNI it accepts any one of three: a migration file showing your current residence type and entry to the country, a passport recording a residence type that it says must not be tourist or permanent, or an entry permit issued by a consulate or under an international agreement. An ordinary visa-free tourist arrival produces none of the three, so in practice no — though note the tourist exclusion is written into the passport option specifically rather than stated as a blanket rule.
Can I get a CUIT before I have a DNI?
Yes. The tax authority publishes a route for a foreign resident without an Argentine DNI: form F. 460 F/PD, your passport, a current immigration certificate showing your expediente number and residency status, and a photo. The CUIT issued is provisional with a maximum validity of two years, and you have ten business days after receiving a DNI to swap it.
What is a CBU and why does everyone ask for it?
The CBU is the 22-digit identifier of an Argentine bank account, and its alias is a readable nickname for the same thing. Argentina settles most payments by bank transfer rather than by card, so a CBU or alias is what you hand over to pay rent, a tradesperson or a coach. Fintech wallets issue a CVU instead, which interoperates for transfers.
Will an Argentine bank charge me for an incoming international transfer?
It is prohibited from charging a commission on foreign currency credited to your own foreign-currency account, under the central bank communication of 18 September 2025. Documented correspondent-bank charges incurred along the way may be passed on at cost.
Should I open a peso account or a dollar account in Argentina?
Usually both. The peso account gives you the CBU everything settles through; the dollar account is where foreign income lands, and since September 2025 individuals receiving service-export income are under no obligation to convert it to pesos.
Is it still worth avoiding the Argentine banking system?
No. The argument for staying out was the gap between the official and parallel exchange rates, and that gap collapsed after currency controls on individuals were lifted in April 2025. A documented paper trail is worth having for a lease, a residency renewal and a tax return.
