U.S. public companies are required by the Securities and Exchange Commission (SEC) to use US GAAP (Generally Accepted Accounting Principles) for financial reporting. While IFRS (International Financial Reporting Standards) is used in over 140 nations, it is not used for domestic SEC filings, although foreign companies operating in the U.S. may use IFRS.
IFRS is used in more than 110 countries around the world, including the EU and many Asian and South American countries. GAAP, on the other hand, is only used in the United States. Companies that operate in the U.S. and overseas may have more complexities in their accounting.
IFRS is principles-based and may require lengthy disclosures in order to properly explain financial statements. It is the established system in the European Union (EU) and many Asian and South American countries. It has not yet been adopted as an official system in the United States.
Declaring (and rightfully so) that their main goal is to protect US investors' interests, the SEC notes that IFRS lacks consistent application, allows too much leeway with judgment, and is underdeveloped in many specific areas, for which the US GAAP has detailed and accepted guidance and established practice ( ...

Incompatibility with Local Tax Regulations
One of the major drawbacks of IFRS adoption is its frequent misalignment with local tax laws and reporting requirements. Many countries have tax systems closely tied to national accounting standards, where taxable income is directly derived from financial statements.
GAAP is used primarily in the United States, while IFRS is adopted by over 195 countries and territories worldwide. Key differences include inventory valuation (LIFO vs FIFO), asset revaluation, and revenue recognition approaches.
IAS 2 prohibits LIFO; US GAAP allows its use.
While the majority of US GAAP companies choose FIFO or weighted average for measuring their inventory, some use LIFO for tax reasons.
Enforcement: GAAP is rule-based, meaning publicly traded US companies are lawfully required to follow its directives. On the other hand, IFRS is standards-based and leaves more room for interpretation and sometimes requires lengthy disclosures on financial statements.
Although IFRS consists of a wide range of standards but its key four primary principles we will summarize below.
