Summary (tl;dr)

The keyword "taxes" is trending as taxpayers prepare for the upcoming 2026 U.S. tax season, marked by significant changes from the "One, Big, Beautiful Bill Act," while globally, the implementation of the OECD's minimum corporate tax continues alongside discussions at the UN for international tax reform.

Essential Background

Historically, tax codes undergo annual adjustments for inflation, but recent legislative actions have brought more substantial shifts. In the U.S., the "One, Big, Beautiful Bill Act" (OBBBA), passed in 2025, made permanent many tax cuts from the 2017 Tax Cuts and Jobs Act (TCJA) and introduced new provisions. Simultaneously, at an international level, the Organisation for Economic Co-operation and Development (OECD) has been leading an initiative, known as Pillar Two or the Global Minimum Tax, to ensure large multinational enterprises pay a minimum effective corporate tax rate of 15% globally, with initial implementation having started in 2024 for some jurisdictions.

The Full Story

As of early December 2025, "taxes" is trending due to the Internal Revenue Service (IRS) urging U.S. taxpayers to prepare for the 2026 filing season, which will reflect the substantial changes introduced by the "One, Big, Beautiful Bill Act" (OBBBA) for the 2025 tax year. These changes include new federal deductions for tips, overtime, and car loan interest, a temporary deduction for seniors, and increased standard deductions. Additionally, the IRS and Treasury Department recently issued multiple notices providing crucial interim guidance on international tax provisions stemming from the OBBBA, affecting areas like foreign tax credits and controlled foreign corporations.

Concurrently, the global implementation of the OECD's Pillar Two, which establishes a 15% global minimum corporate tax, continues to be a major discussion point, with many jurisdictions bringing their domestic legislation into effect around late 2025 and early 2026. There are ongoing international discussions, including within the G7, regarding how the U.S. will interact with this global framework, especially following an executive order from President Trump indicating an intention to withdraw the U.S. from Pillar Two. The United Nations is also actively discussing reforms to the global tax system to better align taxation with where business activities and value creation occur.

Why It Matters

These trending tax developments carry significant implications for individuals and multinational corporations alike. For U.S. taxpayers, understanding the new deductions, increased standard deductions, and the phase-out of paper tax refunds introduced by the OBBBA is crucial for accurate filing and maximizing potential refunds in the upcoming 2026 tax season. The transition to predominantly electronic refunds also necessitates taxpayers ensure they have bank accounts.

Globally, the implementation of the Pillar Two minimum tax could profoundly reshape international corporate tax strategies, aiming to curb profit shifting and ensure fairer taxation of large businesses. The evolving stance of the U.S. on Pillar Two, and the broader UN discussions on global tax reform, highlight a period of significant change in international tax policy, impacting global competitiveness and tax revenue for various nations.
