Argentina’s Law 27.826, known as Inocencia Fiscal II, took effect Friday, 9 October 2026, the day it appeared in the Official Gazette. The government is betting that easing fear of the taxman will bring hidden dollars into the banking system, where decades of enforcement have failed.
The figures explain the gamble. INDEC, the national statistics office, put residents’ foreign-currency cash and deposits abroad at US$268.8 billion on 30 June 2026, according to its September balance of payments report. That figure doesn’t distinguish cash kept at home from money held overseas. Either way, it’s a vast pool of savings outside the formal economy.
The Policy
President Javier Milei promulgated the law through Decree 1160/2026, dated Thursday, 8 October and signed by Milei, Cabinet Chief Diego Santilli and Economy Minister Luis Caputo. Congress passed the measure on 17 September 2026. It amends Law 27.799, the first Inocencia Fiscal law, as well as the Tax Procedures Law.
The centerpiece is a simplified income-tax return for resident individuals and estates. Filers receive a presumption that their figures are accurate unless the tax agency, ARCA, finds a significant discrepancy. The threshold is 15% more tax, a gap above the tax-crime threshold, or fake invoices. ARCA alone must prove its case, drawing on the taxpayer’s return, its own systems and third-party data. If a ruling annuls an ARCA challenge, the agency must refund any payment with interest within 45 working days.
That’s a notable shift in the balance between citizen and state. The tax authority must now make its case, rather than demand that taxpayers disprove it.
How the Money Moves
Participants must route funds through channels authorized by the Central Bank or the National Securities Commission (CNV), the market regulator. Cash paid when signing a property deed at a notary also qualifies. Funds moved through these channels keep the regime’s protection until 31 December 2027.
Banks and other businesses covered by anti-money-laundering rules must treat proof of joining the regime as a favorable sign, though they still have to check their clients. ARCA must let them verify a client’s status through an automated query. The financial intelligence unit, UIF, has 15 working days to tell banks how to treat covered clients.
Fines and Exclusions
Formal tax fines, including penalties for missing a filing deadline, fall 25% automatically for individuals, estates, nonprofit groups and micro, small and medium-sized firms. Large taxpayers, as ARCA classifies them, don’t qualify. A separate regime halves fines for formal breaches committed before 9 October that aren’t final or remain unpaid. Taxpayers must first meet the original obligation, or meet it at the same time, and earlier payments aren’t refunded. ARCA has 30 days to issue rules for halving older fines.
The protections have limits. Large taxpayers may use the simplified return only to file and pay on time, without its safeguards. The same restriction applies to senior officials who held office during the previous five years, including secretaries of state and higher ranks, national and provincial legislators, judges, prosecutors and judicial council members. Users must be Argentine tax residents for the full year, except for the 2025 return. Tourists and foreign investors who don’t live in Argentina aren’t affected.
Rural employers face a different rule. Penalties for failing to register workers with RENATRE, the national register of rural workers and employers, reach a top tier of 1,500,000 to 7,500,000 pesos per worker, roughly US$990 to US$4,950 at about 1,516 pesos to the dollar on 10 October 2026. From 1 January 2027, those fines will rise annually in line with the UVA, an inflation-linked unit of account.
Market Reaction
Banks stand to benefit from any deposit inflow, yet investors haven’t rushed in. Infobae reported on 9 October 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 results at Galicia, a leading Argentine bank, 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.
The law sets no target for how many hidden dollars should reach banks. Any effect is expected to appear later in central bank deposit data.
Why This Matters:
Argentines have kept dollars at home or abroad for decades amid inflation and devaluation, starving the formal economy of capital. This law tests whether lighter enforcement, a shifted burden of proof and lower fines can rebuild trust where mandates failed. It treats private savings as a resource to attract rather than a target to hunt. Success would show up in bank deposits, and therefore in credit and investment, not in new tax collected. But the law sets no target, and bank shares remain deeply depressed. Whether savers believe the protections will outlast the political moment is the open question.
