The US Internal Revenue Service claims that Microsoft Corporation should pay approximately $30 billion in tax refunds, nearly three times the amount the company invested in OpenAI earlier this year. Microsoft plans to appeal strongly against this adjustment, arguing that they have consistently adhered to tax regulations in the US and globally. Interestingly, this tax amount is nearly three times the $10 billion investment Microsoft made in OpenAI at the beginning of 2023, a move announced just days before the company began significant layoffs. Additionally, this tax news surfaced just days before the expected deadline for Microsoft's planned acquisition of video game company Activision Blizzard, a deal worth $68.7 billion. The US Federal Trade Commission had attempted to block this transaction, citing concerns that it aimed to suppress competition for the company's Xbox console series.
