Argentina’s Inocencia Fiscal II law took effect on 9 October. It limits when the tax agency can challenge eligible people who move hidden dollars into the formal financial system. Filers using a simplified income-tax return receive a presumption that their figures are accurate unless the agency finds a significant discrepancy. ARCA, the state’s tax collector, carries the burden of proof.
Who Gets Protection
Congress passed Law 27.826 on 17 September 2026. President Javier Milei promulgated it through Decree 1160/2026, signed with Cabinet Chief Diego Santilli and Economy Minister Luis Caputo and dated 8 October. The law appeared in the Official Gazette the following day.
Resident individuals and estates can use the simplified return. ARCA can challenge a return if it finds at least 15% more tax is due, a gap above the tax-crime threshold or fake invoices. The agency may rely on the taxpayer’s return, its own systems and third-party data to make its case. If a ruling annuls an ARCA challenge, the agency must return any payment with interest within 45 working days.
The program channels funds through institutions that still hold gatekeeping power. Participants must move money through channels authorized by the Central Bank or the National Securities Commission, or pay cash when signing a property deed at a notary. Money moved through those channels keeps the regime’s protection until 31 December 2027.
The Money the State Wants
INDEC, the national statistics office, reported that residents held US$268.8 billion in foreign-currency cash and deposits abroad on 30 June 2026. Its figure doesn’t distinguish dollars kept at home from money in overseas accounts. Argentines have kept dollars at home or abroad amid inflation and devaluation, sometimes calling cash at home “dollars under the mattress.”
The law sets no target for the amount of hidden money that should enter banks. Its impact is expected to appear later in central bank deposit data. Banks and other businesses subject to anti-money-laundering rules must treat proof of joining the regime as a favorable sign, but they still have to check clients. ARCA must provide an automated way for them to verify a client’s status.
The financial intelligence unit, UIF, has 15 working days to tell banks how to treat clients covered by the regime. ARCA has 30 days to issue rules for halving older fines. The system centers not only on tax enforcement but also on financial institutions deciding how customers may handle their money.
Who Gets Fined—and Who Doesn’t
Formal tax fines, including penalties for missing filing deadlines, automatically fall 25% for individuals, estates, nonprofit groups and micro, small and medium-sized firms. Large taxpayers, as ARCA classifies them, don’t qualify. A separate measure halves fines for certain formal breaches before 9 October that aren’t final or remain unpaid, for obligations due since the first law. Taxpayers must first pay or meet the original obligation; earlier payments won’t be refunded.
Large taxpayers may file and pay on time using the simplified return, but they don’t receive its protections. The same limit applies to senior officials who held office during the five years before joining, including secretaries of state and higher ranks, national and provincial legislators, judges, prosecutors and judicial council members. Users generally must have been Argentine tax residents for the full year, with an exception for the 2025 return. Tourists and foreign investors who don’t live in Argentina aren’t affected; foreigners who qualify as Argentine tax residents can, in principle, choose the simplified return.
The law also revises penalties for rural employers who fail to register workers with RENATRE, the national register of rural workers and employers. The heaviest fine ranges from 1,500,000 pesos to 7,500,000 pesos per worker. From 1 January 2027, rural fines will rise annually with the UVA, an inflation-linked unit of account.
The account of the law includes no grassroots or community response. The reported market mood is less confident: Infobae reported that local bank shares had fallen more than 50% in dollar terms since their January 2025 peak on Wall Street. Claudio Maulhardt of Latin Securities, writing about Galicia’s results, said he struggled to be very optimistic about banks. “If Argentina does well,” he added in comments cited by Infobae, “its banks will do well in the future.”
