Argentina has formally committed to implementing the OECD’s Crypto-Asset Reporting Framework, pledging to begin the automatic exchange of information on crypto transactions with other jurisdictions by September 2029, in a step that brings one of Latin America’s most crypto-intensive economies into a global tax transparency system now backed by 77 jurisdictions.
The OECD’s Global Forum on Transparency and Exchange of Information for Tax Purposes announced on Sept. 14 that Argentina had formally committed to CARF, a framework developed with G20 countries to extend cross-border tax information exchanges to crypto assets. The commitment sets a firm deadline for Argentina to start exchanging information with other participating tax authorities.
Notably, the commitment does not immediately create a new crypto tax or reporting regime for Argentine users. Before exchanges can begin, Argentina will need to bring CARF into its domestic legal framework, establish the required reporting system, and put bilateral or multilateral arrangements in place so the collected information can actually be shared with other tax authorities.
## A system built for crypto’s borderless nature
CARF was developed by the Organization for Economic Cooperation and Development together with G20 countries to give tax authorities standardized information about crypto transactions involving their residents, closing a gap left by traditional financial account reporting rules that were never designed for digital assets. The G20 later backed the framework and asked the Global Forum to support its implementation.
The OECD first developed the reporting framework in 2022 before publishing further international tax transparency standards covering digital assets. Argentina becomes the 77th jurisdiction to formally commit, with participating countries scheduled to start exchanges in 2027, 2028 or 2029 depending on their implementation timetable.
Gaël Perraud, chair of the Global Forum, said Argentina’s commitment would give its tax authorities visibility into crypto activity that has so far remained outside their reach. “It will help ensure that Argentina’s tax authorities are equipped with the information they need on transactions in crypto-assets taking place abroad,” Perraud said, adding that the system is intended to address tax evasion and avoidance risks associated with crypto.
The Global Forum will monitor Argentina’s progress toward the September 2029 deadline, while its secretariat provides technical support during implementation. Argentina has been a member of the forum since 2009 and has participated in CARF discussions both as a developing country and as a member of the CARF Group.
## What gets reported, and by whom
CARF is mainly directed at crypto-asset service providers that facilitate transactions for customers, including centralized exchanges and brokers, though depending on their activities some other service providers can fall within scope. Reporting providers are required to collect identifying information about covered users alongside transaction information that can later be exchanged between participating tax authorities.
The records can include a customer’s name, address, jurisdiction of tax residence and tax identification number, together with transaction data covering purchases, sales and transfers by crypto asset. For Argentine authorities, that means standardized information about transactions carried out abroad by residents, which officials can then compare against taxpayers’ domestic filings.
Importantly, CARF does not by itself decide whether a user owes tax on a transaction. Tax liabilities remain governed by the domestic laws of each jurisdiction; the framework only establishes what information service providers collect and how tax authorities exchange it. Self-custody also does not automatically mean a wallet balance is reported, though transactions involving a self-custody wallet can enter the reporting system when they pass through a covered service provider.
## The clock is already running elsewhere
Similar requirements have already begun taking effect in other jurisdictions. Data collection started on Jan. 1, 2026 across 48 jurisdictions, including the United Kingdom and European Union countries, while many participating authorities are preparing for their first information exchanges in 2027.
The reach of the system has limits. A recent crypto tax analysis found that transactions within the practical reach of international reporting systems represented only 14 percent of an estimated 457 billion USD in potentially taxable onchain activity during 2025. Chainalysis said decentralized exchanges, private wallets, peer-to-peer transfers, crypto payments and onchain income accounted for much of the activity outside practical reporting reach.
## Why Argentina matters
Argentina has long ranked among the world’s heaviest adopters of crypto on a per-capita basis, with citizens turning to digital assets amid recurring currency volatility and inflation. That adoption has made the country a significant node in global crypto flows, and its entry into the CARF system means that activity will progressively become visible to tax authorities both at home and abroad.
For the OECD, Argentina’s commitment strengthens the framework’s claim to being a genuinely global standard rather than a rich-country club. For Argentine users, the practical message is that the transition period is finite: domestic implementation, reporting system construction and exchange arrangements must all be completed before September 2029, and each of those steps will bring local rules closer to the international standard.
The message from Buenos Aires to the Global Forum is one of alignment. The message to crypto users in Argentina is simpler: the era of borderless, invisible crypto taxation is drawing to a close, on a schedule that is now written down.
2029 automatic exchange. so three more years of bl Exterior and then everyone’s holdings get reported to AFIP in one shot. good luck to the locals
bl exterior users moving to hardware wallets wont help when the exchanges do the reporting. the data leaks at the offramp, not the wallet
With inflation doing what it does, crypto adoption there is survival not speculation. CARF will not change that, it just pushes more people to privacy chains
survival demand sure, but CARF chases offramps not chains. cash usdt trades in buenos aires are about to get a lot more popular
premium on cash usdt in buenos aires was already 5 to 8 percent last i checked. once reporting starts in 2029 that spread basically becomes the privacy tax people pay to stay off the books
5 to 8 percent was the walk-in cueva rate back in june. post 2029 that spread becomes the afip-free tier and locals will price it like a subscription
cueva spreads going from 8 percent to the afip free tier, you just know someone in buenos aires is building that product right now
the afip free tier framing is bleak but accurate. reporting does not kill the cueva, it just gives the spread an official name
cash USDT in Buenos Aires already trades at a spread. CARF just makes the premium official, the parallel market priced this in years ago
bl Exterior was always a lag, never a shield. once exchanges start reporting in 2029 AFIP gets the full 2026-2028 history dumped on them at once
the 2026 to 2028 history dump is the scary part. AFIP getting three years of retroactive exchange data in one file is a tax collectors dream
77 jurisdictions in CARF now and Argentina joining is significant given the size of their crypto economy. the deadline is firm, that is the notable part
77 jurisdictions and a firm september 2029 date is the headline. the fine print is argentina still has to write the domestic law, and congress there moves slower than the inflation it causes
congress passing a data exchange law before 2029 while inflation is the actual priority, bold of anyone to hold their breath. the 77 jurisdictions will just have to wait
two administrations from now is the optimistic read on the domestic law. ill believe it at the first AFIP filing deadline
first filing deadline is the real test, agreed. but the Global Forum publishes peer reviews, and argentina cares more about that scoreboard than any local law. momentum is on the 77 side
commitment by 2029 means at least two governments and a currency crisis from now here. ill believe the data exchange when i see the AFIP software actually working
true but they said the same about CRS and that one did happen. 77 jurisdictions is a lot of pressure to comply with
no new tax created yet, this is just the reporting plumbing. still, anyone who thought exchange flows would stay invisible forever was dreaming
a 2029 deadline with the domestic law still unwritten is the entire argentine experience in one sentence. the commitment is real, the plumbing is fiction so far
plumbing is fiction so far, fair, but Argentina is the 77th jurisdiction to commit and the Global Forum reviews progress publicly. Milei’s crew cares about looking compliant more than most, that counts for something
caring about the scoreboard and writing the implementing law are different sports. that congress could not pass a budget on time, CARF legislation by 2029 is a hope not a plan
congress passing a CARF law by 2029 is optimistic sure, but milestone fast tracked half the financial agenda with decrees this year. different toolkit now
everyone arguing about 2029 while the fine print says argentina still needs bilateral deals with every partner before a single datum moves. thats the actual bottleneck
77 jurisdictions and a firm date is more than argentina usually commits to on paper. but CRS deadlines slipped years almost everywhere, crypto plumbing is worse
