Do ALL companies have to comply with GAAP?

Not all companies are required to comply with Generally Accepted Accounting Principles (GAAP). Publicly traded companies in the United States must follow GAAP as mandated by the Securities and Exchange Commission (SEC). However, private companies have the option to use GAAP or other accounting frameworks, such as the cash basis or tax basis of accounting, depending on their financial reporting needs and regulatory requirements. Additionally, some smaller entities may choose not to adhere to GAAP if they are not seeking external financing or investment.
