Meta reduced its tax liabilities by $355 million by classifying CEO Mark Zuckerberg as a researcher. The company attributed $4.1 billion of Zuckerberg's stock option income from 2012 and 2013 to research wages. The Internal Revenue Service disputes this classification, arguing the compensation covered work performed between 2008 and 2010, while Meta maintains the options were tied to coding work from 2005.

The company also categorizes its AI data centers as pilot models to claim tax credits on hardware purchases. Meta currently lists $18.74 billion in tax benefits as uncertain, primarily due to ongoing research credit disputes. Meanwhile, Elon Musk exercised 303.96 million Tesla stock options in June, resulting in a paper gain of approximately $116 billion, which is 28 times the amount Meta claimed for Zuckerberg.

While Tesla holds $1.83 billion in unused federal research credits, tax regulations generally exclude top executives from research-related tax breaks unless they directly conduct or supervise research. The US Tax Court has yet to issue a ruling on the Meta case, which will determine if executive stock option payouts can legally qualify as research wages under current federal guidelines.
