Opening a Bank Account in Argentina 2026: What Foreigners Actually Need
ARGENTINA · EXPAT GUIDE
Key Facts
- —The real gate Not the identity card but a tax key. The CDI exists for people without one and is free.
- —The document A passport is accepted until you have held residency one year. After that only the identity card.
- —The account type Ask for a savings account. A current account is taxed on both credits and debits.
- —The dollars Dollar savings accounts are allowed. Buying dollars at the official rate is what is restricted.
- —The street rate The informal rate sat about one percent above the official one in September 2026.
- —The catch Non-residents still need central bank approval to buy dollars. The 2025 opening did not reach them.
Most English-language advice on Argentine banking is wrong in both directions at once. It understates how much was liberalised and overstates how much of the currency control is gone.
Opening a bank account in Argentina as a foreigner is easier than the guides suggest. The obstacle to a bank account is not the national identity card.
The obstacle is a tax key, and the central bank requires one before any account opens. There are three of them and foreigners usually need the third.
Employees and pensioners get a labour key. People carrying on a taxable activity get a tax number.
Everyone else applies for an identification key called the CDI. It exists precisely for people with neither of the other two, and it is free.
The tax authority states plainly that it is for opening accounts and carrying out financial operations. A residency receipt from the migration office is accepted as proof of identity for it.
Which Document Proves Who You Are
Central bank rules set out a specific sequence for foreigners. Someone on a transitory or provisional residence uses the passport of their country of origin.
Someone granted temporary or permanent residence less than a year ago may use either the passport or the Argentine card. Either is accepted.
After one year of residency, only the Argentine card will do. That cliff is not in most published guides and it catches people out.
A non-resident presents a document from their own country, legalised or apostilled. If it is not in Spanish it needs a translator registered in Argentina with a certified signature.
The Right to Be Given an Account
Banks that let customers use cash machines must open a universal free account on request. It is an obligation, not a favour.
Identification follows the same rules described above, so a passport qualifies. The account is in pesos only and you must hold no other sight account anywhere.
That is the strongest card a foreigner holds if a branch refuses. Ask for it by name.
What no rule guarantees is a bank’s appetite for the paperwork. Regulation permits a passport-only account; commercial practice varies and no bank publishes its policy.
Savings Account, Not Current Account
This is the most useful piece of tax advice in the whole process. A current account attracts a tax of six per thousand on credits and six per thousand on debits.
That is 1.2 percent on every round trip. Savings accounts are expressly exempt from it.
A peso savings account must also be free by law. Opening, maintenance, one debit card, the bank’s own machines and internet banking all carry no charge.
That guarantee does not extend to dollar accounts. Banks may charge maintenance on a dollar savings account, so ask.
Dollars: What Is Allowed and What Is Not
Holding dollars in an Argentine bank account is unrestricted. Savings accounts are permitted in pesos, dollars, euros and renminbi, with no rule about nationality.
Buying dollars at the official rate is a different question. Residents lost the old monthly cap in April 2025, but a condition came back in stages that autumn.
Anyone buying at the official rate now signs an undertaking not to buy securities settling in foreign currency for ninety days. That covers the parallel financial rates.
So the control was not abolished. It was converted from a limit on quantity into a limit on behaviour.
Non-residents were never included in the opening at all. They still need prior central bank approval to buy foreign currency through the official market.
The one exception is small. A non-resident tourist may buy back up to US$100 at the official rate.
Even that requires proof of a prior sale. The system must show they sold at least that much within the previous ninety days.
Getting Money In
This is where the real liberalisation happened. Individuals no longer have to convert foreign earnings into pesos.
A cap on service exports was removed in September 2025. The exemption widened to all services and to goods in April 2026.
A freelancer invoicing abroad can therefore be paid in dollars and keep them. That is a genuine change from the old regime.
Banks may not charge commission to residents on incoming foreign currency credited to a foreign-currency account. Correspondent charges may only be passed through at cost.
A transfer into a dollar account keeps the money in dollars. A remittance service usually converts it into pesos, which is now rarely what you want.
The Rates, and Why the Old Advice Is Obsolete
On 11 September 2026 the official wholesale reference was 1,508.50 pesos to the dollar. The average retail selling rate was 1,531.73.
The informal rate was around 1,545, roughly one percent above the retail official rate. The historic premium that made cash king has effectively closed.
The financial rate used for securities settlement sat near 1,598, some six percent over the wholesale rate. That is where the residual friction now lives.
The currency has traded inside a published band since April 2025. On 11 September the floor stood at 734.08 pesos to the dollar and the ceiling at 1,894.30.
The market rate sat well inside both. In practice the band has not bound and the peso floats.
Does Holding Pesos Make Sense
Inflation was 1.7 percent in August 2026 and 33.5 percent over twelve months. The annual figure looks backward and overstates the current pace.
A thirty-day time deposit paid 21.51 percent nominal, which compounds to about 23.8 percent. Against recent monthly inflation that is roughly break-even.
Over the year to September the peso weakened only about ten percent against the dollar. A peso time deposit therefore beat holding dollars, by a wide margin.
Do not read that as a forecast. It happened because the exchange rate was stable inside a band that never bound, and that can change.
A savings account is a different matter. It pays close to nothing and loses value steadily, so use it to move money rather than to keep it.
Cards and One Surcharge to Watch
Argentine-issued cards carry a 30 percent surcharge on spending abroad. It is a prepayment against income tax and registered taxpayers can recover it.
That surcharge does not apply to a foreign card used inside Argentina. Foreign cards now receive a rate close to the official one.
Limits on cash advances abroad on locally issued cards were removed in April 2026. Those had been as low as US$50 per transaction.
The Order to Do It In
Settle your migration status first, because everything else depends on it. A provisional residency certificate unlocks both the passport rule and the tax key.
Then obtain the tax key. Then assemble identity documents, apostilled and translated before you travel rather than after.
Then open the account in a branch. Digital onboarding is built around the Argentine identity card and will usually fail without one.
Ask for the peso and dollar savings accounts together. The common mistake is arriving and trying to open a bank account before any of the previous steps are done.

Frequently Asked Questions
Can I open an Argentine bank account with just a passport?
The rules permit it, using a passport plus a CDI tax key. Whether a given branch will do it is a commercial decision, not a legal one.
Do I need a DNI?
Not at first. A passport is accepted while you are on a provisional or transitory residence, and for the first year of temporary or permanent residence.
Can foreigners hold dollars in Argentina?
Yes. Dollar savings accounts are permitted and holding, receiving and withdrawing dollars is unrestricted.
Can I buy dollars at the official rate?
Residents can, but must undertake not to buy foreign-currency securities for ninety days. Non-residents still need central bank approval.
Savings account or current account?
Savings. Current accounts are taxed six per thousand on credits and on debits, while savings accounts are exempt.
