Mexican GAAP is the country’s financial reporting framework, formally called the Normas de Información Financiera (NIF) and maintained by an independent standard-setter, the Consejo Mexicano de Normas de Información Financiera (CINIF).1Institute of Chartered Accountants in England and Wales (ICAEW). Accounting in Mexico Its structure closely resembles IFRS, and after two decades of convergence work many individual standards track their IFRS counterparts. The gaps that remain are not cosmetic. NIF triggers mandatory inflation restatement at a much lower threshold than IFRS, U.S. GAAP has no equivalent mechanism at all, and NIF diverges from both on cash flow classification, consolidation edge cases, and Mexico’s constitutionally mandated employee profit sharing.
How the Standards Are Organized
NIF is grouped into lettered series. Series A sets out the conceptual framework. Series B covers the financial statements as a whole, including the statement of financial position, comprehensive income, and consolidation. Series C handles specific line items such as inventories, receivables, and property. Series D deals with topical areas like employee benefits, leases, and liabilities. The hierarchy mirrors the topic-based organization of IFRS, and where no specific Mexican standard exists, NIF uses IFRS as supplementary guidance.
Who Uses NIF
Commercial entities preparing statutory financial statements in Mexico generally use NIF. That covers private companies of every size, publicly traded companies on the Mexican Stock Exchange (BMV), and regulated financial institutions, which layer sector-specific rules from their regulators on top of the NIF baseline.
Companies cross-listed on U.S. exchanges have a choice. They can adopt IFRS as issued by the IASB for their SEC filings, which the SEC accepts without any reconciliation to U.S. GAAP.2U.S. Securities and Exchange Commission.

Foreign Private Issuers – Financial Reporting Manual Several large Mexican multinationals have moved to IFRS for consolidated reporting for this reason, while their domestic subsidiaries continue using NIF locally.
Inflation Accounting: The Biggest Divergence
The largest substantive gap between Mexican GAAP and international standards is how each framework accounts for inflation.
Under NIF B-10, Mexico classifies an economy as inflationary when cumulative inflation over the prior three years reaches or exceeds 26%, roughly 8% annually on average. When that threshold is met, companies restate all non-monetary assets and liabilities (property, equipment, inventory, stockholders’ equity) to reflect current purchasing power using the Índice Nacional de Precios al Consumidor (INPC), Mexico’s national consumer price index. Monetary items such as cash and receivables stay at nominal value. The gap between restated non-monetary items and unchanged monetary items generates a gain or loss on net monetary position, which flows through the income statement, and restated asset values also change subsequent depreciation and amortization expense for years afterward.
IFRS has an equivalent standard, IAS 29, but it applies only when cumulative three-year inflation approaches or exceeds 100%, nearly four times the NIF trigger. In practice IAS 29 captures only extreme cases like Venezuela or Zimbabwe. NIF B-10, by contrast, captures the moderate inflationary periods that show up more often in Mexico’s economic history. U.S. GAAP has no domestic mechanism of this kind at all.
Where does Mexico stand right now? Cumulative three-year inflation for 2022 through 2024 comes to roughly 19.7%, built from annual rates of about 7.9% in 2022, 5.5% in 2023, and 4.7% in 2024.4St. Louis Fed – FRED. Inflation, Consumer Prices for Mexico That sits below the 26% threshold, so NIF B-10 restatement is currently suspended. The standard remains on the books and reactivates if inflation accelerates enough to cross the trigger again.
Cash Flow Classification
Interest and dividends are handled differently in each of the three frameworks, and the differences change reported operating cash flow.
- Under NIF, interest and dividends received are operating activities; interest and dividends paid are financing activities.
- Under U.S. GAAP, interest paid and interest and dividends received are all operating; only dividends paid are financing.
- Under IFRS (IAS 7), companies choose: interest paid can be operating or financing, interest received can be operating or investing, dividends received can be operating or investing, and dividends paid can be operating or financing.5International Financial Reporting Standards Foundation. Classification of Interest and Dividends in the Statement of Cash Flows
Two companies with identical economics can report different operating cash flows depending on which framework they follow. Comparing a NIF filer to a U.S. GAAP filer, interest paid shifts from operating (U.S. GAAP) to financing (NIF), making the NIF filer’s operating cash flow look higher and its financing cash flow look lower. Reclassify before comparing.
Consolidation
NIF B-8 defines control using the same three elements as IFRS 10: power over the investee’s relevant activities, exposure to variable returns, and a link between that power and those returns. The differences sit at the edges.
IFRS 10 explicitly recognizes de facto control, meaning an investor can be treated as controlling an entity with less than 50% of voting shares if the remaining shareholders are widely dispersed and passive. NIF B-8 is less explicit on this point. Mexican regulatory accounting criteria also carve out exceptions for investment companies and certain non-financial sector entities, which may not be consolidated even when a holder exercises significant influence.6Grupo BMV. Diferencias Contables Entre Criterios de la CNBV e IFRS Under IFRS 10, those same entities would likely fall inside the consolidation perimeter. Special purpose entities are handled through specific NIF guidance, whereas IFRS 10 folds them into its broader control model. The same corporate structure can end up with a different consolidation scope depending on which framework applies.
Employee Profit Sharing (PTU)
Mexico’s constitution requires employers to distribute 10% of their pre-tax profits to employees each year, a program called Participación de los Trabajadores en las Utilidades (PTU). Neither IFRS nor U.S. GAAP has an equivalent obligation, and international analysts frequently misread the line.
The profit base for PTU comes from the company’s annual income tax return filed with Mexico’s tax authority (SAT), not the NIF accounting profit. The amount is split into two equal halves: one distributed equally among all employees, the other in proportion to each employee’s salary. Individual payouts are capped at three months of the employee’s wages.
Under NIF D-3, PTU is treated as an employee benefit and recognized as an expense on the income statement. It is not a distribution to equity holders. A Mexican company’s reported profit will be lower than an otherwise identical company in a jurisdiction without mandatory profit sharing, and for labor-intensive businesses the difference can be material.
What This Means for U.S. Filers and Parent Companies
If you file with the SEC as a foreign private issuer using NIF, you owe a full quantitative reconciliation to U.S. GAAP. The 2026 deadline for a Form 20-F covering fiscal year 2025 is April 30, 2026, assuming a December 31 year-end.7Broadridge. 2026 SEC Filing Deadlines and Holidays When NIF B-10 inflation accounting is active, unwinding the INPC-based restatement of assets and equity is the largest reconciliation adjustment. Even when B-10 is suspended, cash flow classification, consolidation scope, and PTU still generate reconciling items.
U.S. parent companies with Mexican controlled foreign corporations file IRS Form 5471 for each subsidiary annually. When the subsidiary keeps its books under NIF, the filer indicates this on the form using Item G, Code 03.8Internal Revenue Service. Instructions for Form 5471 Schedule H then converts NIF-basis book income into earnings and profits for U.S. tax purposes, and every material NIF-versus-U.S.-tax difference (inflation restatement if active, PTU expense, depreciation differences) has to be run through that calculation. Peso-denominated transactions separately generate foreign currency gains or losses under IRC Section 988, generally treated as ordinary.9Office of the Law Revision Counsel. 26 U.S. Code 988 – Treatment of Certain Foreign Currency Transactions Those currency effects can move in the opposite direction from NIF inflation adjustments on the same underlying event, which is why the E&P work needs the Mexican accounting team and the U.S. tax team on the same page.
