You live in the U.S. and someone in Argentina must deal with ARCA for you: Form 3283, signed from here

What Form 3283 is for

It is the form one person uses to authorize another to act on their behalf before ARCA — the Agencia de Recaudación y Control Aduanero, which replaced AFIP as Argentina's federal tax and customs agency. There are two versions, and it helps to know which one you are being asked for:

• F.3283 (authorization). For filings and proceedings. The form itself lists the powers you can delegate: receiving notices in case files, signing tax returns and extension requests, withdrawing documents, filing appeals, collecting refunds, among others. It also states that one authorization must be prepared per tax.
• F.3283/F (authorized relationship administrator). For individuals: you grant someone "full power" to act as your Administrador de Relaciones before ARCA and to use all of the agency's online services on your behalf, with their own tax login. This is the version that solves day-to-day matters from a distance.

Which one fits your case is for your accountant in Argentina to decide. The form is the key; they know which doors it opens.

When an emigrant needs it

• An inheritance. The estate has its own tax front, and someone has to appear before ARCA for the undivided estate or for the heirs.
• A rented property. Rental income keeps generating obligations in Argentina even though you live abroad.
• A sale. Selling real estate or a car in Argentina involves steps before ARCA that someone has to carry out.
• The wealth tax (Bienes Personales). As long as you remain registered or hold assets within its scope, there are annual filings.
• Deregistration. Closing out taxes, changing your tax domicile, or wrapping up what stayed open when you left.

In every one of these the constraint is the same: almost everything is done online with a personal tax login, and the login is personal. Form 3283/F is the formal mechanism for someone else to operate with theirs on your behalf. Which exact filing applies to you is your accountant's call; without the authorization, they cannot even start.

What ARCA requires for the signature

This is the point that trips up people living abroad. Form 3283 says, in its note (d): when the authorization is not granted before agency employees, "the signature of the grantor must be authenticated by: banking institutions, justices of the peace, heads of civil registry offices, police commissioners, notaries (escribanos o notarios) anywhere in the country, with certifying authority under the rules of the jurisdiction in which they act." Form 3283/F says the same in short form: a bank, a justice of the peace, a civil registry head, or a notary (escribano público).

Notice "anywhere in the country": the list is written for someone signing in Argentina. ARCA publishes no specific instruction for signatures certified abroad — I looked through its forms and its FAQ database, and it is not there. What exists are the general rules on how a foreign document enters Argentina, and those are the rules that apply.

How to meet it from the United States

There are two routes.

1. The Argentine consulate. Consulates certify signatures: you book an appointment, show up in person with your ID, and sign in front of the consular officer. It is the textbook route and needs neither apostille nor translation, because the certifying official is Argentine. Each consulate sets its own fee; the limit is practical — appointments, distance, and weekdays.

2. Florida Notary Public + apostille. You sign the form by video before a Notary Public. I am a Florida Notary Public authorized for online notarization (commission HH 652310, verifiable in the state registry) and a Public Accountant (Argentina), so I understand the form you are signing even though I do not fill it in. Then:

• The Florida Department of State apostilles the notarial certificate. Argentina and the United States are parties to the Hague Convention of 1961 (Argentine Law 23,458): the apostille replaces consular legalization (arts. 2 and 3) and certifies the notary's signature and capacity (art. 5).
• In Argentina, a licensed public translator translates the notarial certificate and the apostille, which are in English (Law 20,305, art. 6), and the translators' association legalizes the signature. The form itself is already in Spanish — what gets translated is the certification.
• Your representative files everything at the agency office. For Form 3283/F, their signature is additionally authenticated by an ARCA agent at the office, in person. That part of the process is theirs, not yours.

An honest caveat: the office that receives the form is the one that evaluates it. Before you sign, have your accountant confirm with that office that the "foreign notary + apostille + translation" circuit works for your case. It is the circuit the general rules allow; the final sign-off comes from the ARCA agent, not from me.

The English-certificate trap

Almost everyone asks the same thing: "Have the notary certify in Spanish so I can skip the translator." It cannot be done, for two reasons that chain together:

• The Florida Department of State only apostilles documents whose notarial statement is in English — it says so in its list of accepted documents. A certificate in Spanish does not get apostilled, and the apostille is what ARCA and the other agencies require to authenticate a foreign certification, save for the exceptions in Article 3 of the Convention.
• And because it is in English, Argentina requires it translated (Law 20,305). That is not the translator being difficult; it is the consequence of the first point.

The worse variant: asking the notary to fill in the form or tell you which boxes to tick. A Notary Public certifies your signature; what goes on the form is your accountant's job. You come to the session with the form already completed and unsigned.

What I do, what your accountant does

• Your accountant in Argentina: picks the form, completes it, coordinates the translator, and files it together with your representative.
• You: one video call with a valid ID, from any state.
• Me: I check that the form is ready to be signed, perform the remote notarization, obtain the apostille, and send you the PDF as soon as it is ready; the original travels by tracked courier. What depends on me takes 3 to 4 business days; shipping is separate and its timing depends on the destination. From USD 250 per document.
