Argentina: A Private Wealth Law Overview
Structural Reform
The victory of President Javier Milei in the October 2025 midterm elections set the tone for the beginning of 2026. As the most voted political force nationwide, the ruling party expanded its representation in Congress – effective as of December – and, although it still lacks an outright majority, it has managed to advance its legislative agenda through consensus-building with other political blocs.
During the first few months of 2026, two highly relevant laws were enacted, reflecting both the progress of the government's reform programme and its ability to navigate a still fragmented political landscape. These initiatives consolidate a shift in economic and regulatory policy and establish a new framework within which both clients and legal advisers must operate.
Tax Innocence Law
Argentina's tax system has historically been characterised by high tax pressure, increasing regulatory complexity and sustained levels of litigation, against a backdrop of persistent inflation and foreign exchange restrictions. This environment has contributed to significant informality and a structurally tense relationship between taxpayers and the tax authorities.
Law No 27,799 introduces a meaningful shift in approach, seeking to redefine that relationship based on a presumption of compliance and good faith on the part of taxpayers. The reform includes amendments to the criminal tax regime (thresholds have been increased incorporating automatic adjustment mechanisms), shorter statute of limitations periods, and the creation of a simplified income tax filing regime for certain taxpayers. Its overarching objective is to facilitate compliance, reduce disputes and encourage formalisation, concentrating enforcement efforts on significant tax evasion and moving towards a model aligned with enhanced legal certainty standards.
Labor Modernization Law
This law introduces structural changes to Argentina's employment framework, primarily aimed at reducing litigation and promoting formal employment through the flexibilisation of certain legal institutions.
However, its implementation has faced immediate judicial challenges. Argentina's National Labor Court of Appeals has lifted the preliminary injunction that had suspended a significant portion of the country's Labor Modernization Law, allowing the previously blocked provisions to take immediate effect. As a result, the labour reform provisions that had been on hold are now enforceable again on an interim basis, restoring the law's original scope while litigation continues.
However, the ruling is procedural in nature and does not constitute a decision on the merits. The court has yet to rule on the substantive legal challenges to the reform, meaning the outcome remains uncertain. The case continues before the judiciary, and a definitive judicial determination on the law's validity is still pending.
Within this framework, the Incentive Regime for Medium-Sized Investments (Régimen de Incentivo para Medianas Inversiones – RIMI) was also introduced – a tax promotion framework aimed at fostering productive investment by micro, small and medium-sized enterprises. The regime focuses on investment in the real economy, including capital goods, productive infrastructure and energy efficiency initiatives, while expressly excluding financial or speculative investments. Key benefits include accelerated depreciation for corporate income tax purposes and early refund of VAT input tax credits. While RIMI is positioned as a relevant tool to strengthen value chains and promote exports, its effectiveness will largely depend on macroeconomic stability and private sector confidence.
Broader tax reform: a gradual approach
In parallel, a broader tax reform was under consideration, including reductions in corporate income tax rates and exemptions on the transfer of equity interests in local companies. These initiatives were ultimately removed from the fiscal chapter of the Labor Reform Law following pressure from provincial governors, who opposed any measures that would reduce revenue from taxes subject to federal co-participation arrangements. Given the limited fiscal space and the political constraints imposed by the provinces, the government opted to prioritise fiscal consolidation. The administration has instead adopted a gradual approach through targeted adjustments while deferring more comprehensive reforms to a later stage contingent upon improved fiscal performance. This strategy reflects a balance between fiscal prudence and incremental tax relief, aiming to ease the overall burden without compromising public finances.
Outlook for private clients
The legislative developments of early 2026 are unfolding against a broader macroeconomic backdrop that is itself significant for private clients. Following years of exchange rate instability and capital controls, the government has made meaningful progress towards monetary normalisation, including a gradual liberalisation of foreign exchange restrictions and the consolidation of a unified exchange rate. Inflation, while still elevated, has shown a sustained downward trend. Crucially, the current administration has signalled a markedly different attitude towards high-net-worth individuals and private capital – one that is pro-investment and explicitly opposed to the punitive fiscal measures that characterised previous governments. This shift in tone, while not yet fully translated into comprehensive legislative reform, is already reshaping the environment in which private clients plan and make decisions.
While recent history, including the extraordinary tax on big fortunes, incredibly high personal asset tax rates and an increasingly aggressive tax administration, still weighs on private client perceptions, Milei's electoral victory appear to bring a degree of stability and mid-term policy continuity that was previously absent. For private clients, this translates into reasonable confidence that the current administration's commitment not to introduce new taxes nor increase the existing ones is a non-negotiable principle.
Beyond the specific and concrete tax measures already implemented, the most relevant shift for high-net-worth individuals (HNWIs) has been a renewed sense of certainty and peace of mind over the past two years under the current administration. After a long period of sustained tax pressure, HNWIs were operating under a permanent defensive mindset, focused mainly on protecting liquidity and financial assets abroad.
That dynamic has shifted, and families are focusing on long-term planning not exclusively driven by asset protection and tax efficiency, with a more strategic view of preserving and growing family wealth among generations, allowing for discussions around governance and generational transition that for years were overshadowed by urgency. Of course, the continuity of this new mindset will depend on how next year unfolds, as it will be a key election year.
