上千家美国企业排队“退税”，尴尬的美国关税战试图挽尊

Core Viewpoint - The recent U.S. Supreme Court ruling has led to a significant wave of tax refund claims from American businesses, as it deemed certain tariffs illegal, prompting a halt to their collection. However, the introduction of new tariffs under Section 122 of the Trade Act of 1974 by President Trump adds a layer of uncertainty to the situation [1][5][7]. Group 1: Tariff Changes and Refunds - Over a thousand U.S. companies, including Costco, are seeking refunds for tariffs paid, amounting to potentially over $175 billion [1][5]. - The Supreme Court's ruling on February 20 declared tariffs imposed under the International Emergency Economic Powers Act (IEEPA) illegal, effective from February 24 [1][4]. - The new tariffs under Section 122 are set to add an additional 10% on global goods, with Trump indicating a potential increase to 15% shortly thereafter [1][7]. Group 2: Economic Implications - The Tax Foundation estimates that the IEEPA tariffs have increased the average tax burden on American households by approximately $1,000 in 2025, with an additional $1,300 expected in 2026 if continued [4]. - BCA Research predicts a short-term decline in federal tax revenue by 0.5% to 1% of GDP due to the ruling, potentially leading to a slight increase in the budget deficit and upward pressure on bond yields [4][5]. Group 3: Legal and Administrative Challenges - The refund process for the tariffs is expected to be complicated and lengthy, with estimates suggesting it could take 1 to 2 years for importers to receive their refunds [5][6]. - Legal challenges regarding the necessity of refunds are anticipated, which may prolong the resolution of these issues [5][6]. Group 4: International Reactions and Trade Relations - The ruling has created uncertainty for trade agreements previously negotiated under the IEEPA, with varying impacts on different countries [8][11]. - The European Union has called for transparency from the U.S. regarding the ruling and is considering suspending trade agreements until clarity is provided [11][12]. - Countries like Switzerland and South Korea are preparing for the possibility of permanent tariffs and are seeking to maintain balanced trade agreements with the U.S. [12].
