Argentina’s Inocencia Fiscal II law took effect on Friday 9 October, the day it appeared in the Official Gazette. It is President Javier Milei’s latest attempt to draw hidden dollars, kept at home or abroad, into Argentine banks.
For US investors, the stakes sit with Argentine bank shares traded on Wall Street, which depend on deposit growth and confidence. Inocencia Fiscal II protects people who file a simplified income-tax return from most challenges by the tax agency, and it cuts some fines.
What the Law Changes
Law 27.826 amends Law 27.799, the first Inocencia Fiscal (Fiscal Innocence) law, and the Tax Procedures Law. Congress passed it on 17 September 2026, and the president promulgated it by Decree 1160/2026, dated Thursday 8 October.
The decree carries the signatures of Milei, Cabinet Chief Diego Santilli and Economy Minister Luis Caputo. Milei, a libertarian economist, has governed Argentina since December 2023 on a programme of spending cuts and deregulation.
At the core of Inocencia Fiscal II is a simplified income-tax return for resident individuals and estates. Those who choose it get a presumption of accuracy, so the tax agency must accept their figures unless it finds a significant discrepancy.
The agency is ARCA, the Agencia de Recaudación y Control Aduanero, which collects taxes and customs duties. Under the new text, a discrepancy is significant if ARCA finds at least 15% more tax, a gap above the tax-crime threshold, or fake invoices.
The burden of proof lies only with ARCA, which may use just the taxpayer’s return, its own systems and data from third parties. If a ruling later annuls an ARCA challenge, the agency must refund any payment with interest within 45 working days.
Why Hidden Dollars Matter
Argentines have saved in US dollars for decades, after repeated bouts of inflation and devaluation. Many keep the notes at home, which is why locals speak of dollars under the mattress.
INDEC, the national statistics office, put residents’ foreign-currency cash and deposits abroad at US$268.8 billion on 30 June 2026. The figure comes from its September balance of payments report, covered in Argentina’s mattress dollars report.
Inocencia Fiscal II tries to bring part of those hidden dollars into the formal system. People in the simplified regime must move funds through channels authorised by the Central Bank or the National Securities Commission (CNV), the market regulator.
Cash paid when signing a property deed at a notary also counts as compliant. Until 31 December 2027, funds moved this way keep the regime’s protection, under the law’s text.
Banks and other firms bound by anti-money-laundering rules must treat proof of joining the regime as a favourable sign. They still have to check their clients, and ARCA must let them confirm a client’s status through an automated query.
Fines Cut for Individuals and Small Firms
Fines for formal breaches, such as missing a filing deadline, fall 25% automatically for individuals, estates, non-profit groups and micro, small and medium-sized firms. Large taxpayers, as classified by ARCA, do not qualify.
A second regime halves fines for formal breaches before 9 October that are not final or remain unpaid, on obligations due since the first law. Taxpayers must comply with the original obligation first or at the same time, and earlier payments are not refunded.
The law also rewrites the fines for rural employers who fail to register workers with RENATRE, the national register of rural workers and employers. The heaviest fine runs from 1,500,000 pesos (about US$990) to 7,500,000 pesos (about US$4,950) per worker.
Those conversions use about 1,516 pesos to the US dollar on 10 October 2026. From 1 January 2027, the rural fines will rise each year in line with the UVA, an inflation-linked unit of account.

Who Is Left Out
Large taxpayers may file the simplified return, but only to file and pay on time, without its protections. The same limit applies to senior officials who held office in the five years before joining.
That group includes secretaries of state and higher ranks, national and provincial legislators, judges, prosecutors and members of the judicial council. Users must also be Argentine tax residents for the whole year, except for the 2025 return.
What It Means for You
For tourists and foreign investors who do not live in Argentina, nothing changes at the airport, the exchange counter or the brokerage account. Foreigners who count as Argentine tax residents can, in principle, choose the simplified return.
For investors, the test is whether hidden dollars turn into bank deposits in the coming months. Infobae reported on 9 October that local bank shares have fallen more than 50% in dollars since their January 2025 peak on Wall Street.
If hidden dollars reach banks, those lenders would have more money to lend.
Writing on results at Galicia, a leading Argentine bank, Claudio Maulhardt of Latin Securities said he struggles 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.
What Is Not Known
Inocencia Fiscal II sets no target for how many hidden dollars should reach banks. Its effect will only show in later central bank deposit data, and INDEC’s headline figure does not split cash at home from accounts abroad.
The UIF, Argentina’s financial intelligence unit, has 15 working days to tell banks how to treat clients in the regime. ARCA has 30 days to issue the rules for halving older fines.
