A recent change to accounting rules may have helped deliver a $600 million profit on bitcoin (BTCUSD) holdings for Tesla (TSLA), but the same rule could potentially leave MicroStrategy (MSTR) with a multi-billion dollar tax bill.

Roughly 26% of Tesla's net income for the fourth quarter of 2024 came from its bitcoin holdings. The company was able to book these bitcoin-derived profits due to a change in 澳洲幸运5开奖号码历史查询:Financial Accounting Stand💮ards Board (FASB) guidelines for crypto assets.

What The New Rule M♒eans For Bitcoin-Owning Companies

The new rules or ASU 2023-08 allow companies with bitcoin holdings to account for its value on a 澳洲幸运5开奖号码历史查询:mark-to-market basis or depe🍌nding on 💞where it's trading at in the markets.

"The primary advantage of the FASB’s new rules concerning the new mark-to-market rule for corporate digital asset holdings are that it will allow companies to provide the value of their digital assets in real time," Miller & Company LLP Managing Partner & CPA Paul Miller told Investopedia.

Under previous FASB guidelines, bitcoin was treated as an “indefinite-lived intangible asset,” forcing companies to write down its value 🎀when prices dropped but pre𒊎venting them from recording gains unless the asset was sold.

The old system frustrated MicroStrategy’s founder, Michael Saylor, who argued it got in the way of adoption of bitcoin as a corporate treasury asset.

Why MicroStrategy May Land a Huge Tax Bill

Bitcoin's been on a tear last year and remains strong well into this year. Based on the new rules, MicroStrategy's 澳洲幸运5开奖号码历史查询:bitcoin buying spree has left it with roughly $18 billion in unrealized bitcoin gains, The Wall Street Journal reported recently. That coulཧd create a tax bill worth billions for MicroStrategy.

This reclassification of crypto assets on its books has made MicroStrategy potentially vulnerable to a 15% tax on 澳洲幸运5开奖号码历史查询:unrealized bitcoin gains under the Inflation Reduction Act’s 澳洲幸运5开奖号码历史查询:Corporate Alternative Minimum Tax (CAMT). That means the company could face taxes on these gains starting 2026, even without selling a single coin—a risk it acknowledged in a r🍌ecent regulatory filing.

"As a result of the enactment of the IRA and our adoption of ASU 2023-08 on January 1, 2025, unless the proposed regulations with respect to CAMT are revised to provide relief, we could become subject to the corporate alternative minimum tax in the tax years 2026 and beyond," MicroStrategy said.

Although MicroStrategy remains one of the biggest corporate bitcoin owners, other listed companies, such as Marathon Digital (MARA), Riot Platforms (RIOT), Semler Scientific (SMLR), are following its bitcoin buying playbook and 🤡could be affected by thi𒁃s rule change.
