IFRS 18, effective 2027, mandates a strict, three-category structure (operating, investing, financing) in the income statement with defined subtotals like "Operating Profit" and "Profit Before Financing and Taxes". It also forces disclosure of management-defined performance measures (MPMs) and requires more detailed disclosure of expenses by nature within functions (e.g., depreciation). In contrast, US GAAP does not require these specific, standardized income statement subtotals and allows more flexibility in, or differs on, expense classification, such as the presentation of financial costs.

When comparing US GAAP accounting to IFRS accounting?

A prime difference between GAAP and IFRS is in how they account for inventory expenses.

Whereas IFRS only allows the use of the FIFO method, the LIFO method is strictly prohibited.
