Mexican GAAP is the body of accounting rules known as the Normas de Información Financiera, or NIF, issued by Mexico’s independent standard-setter, the Consejo Mexicano de Normas de Información Financiera (CINIF).1Institute of Chartered Accountants in England and Wales (ICAEW). Accounting in Mexico Every commercial entity preparing statutory financial statements in Mexico uses NIF, from small private companies to issuers on the Mexican Stock Exchange. The framework looks a lot like IFRS on the surface, and CINIF has spent more than two decades deliberately converging the two, but several material differences remain. The biggest is inflation accounting, which NIF triggers at a far lower threshold than IFRS and which U.S. GAAP does not address at all. Cash flow classification, consolidation scope, and a mandatory employee profit-sharing expense are the other places where the frameworks part ways.
How the NIF Framework Is Structured
The standards are organized into lettered series, which mirrors the topic-based organization of IFRS.
- Series A sets out the conceptual framework underlying everything else.
- Series B covers financial statements as a whole, including the statement of financial position, comprehensive income, and consolidation.
- Series C addresses specific line items such as inventories, receivables, and property.
- Series D covers topical areas such as employee benefits, leases, and liabilities.
Where no Mexican standard addresses a transaction, NIF uses IFRS as supplementary guidance. Financial institutions layer sector-specific rules from their regulators on top of this baseline.
Who Reports Under NIF
All commercial entities preparing statutory financial statements in Mexico generally use NIF. That includes private companies of every size, publicly traded companies on the BMV, and regulated financial institutions.
Companies cross-listed on U.S. exchanges have a choice. They can adopt IFRS as issued by the IASB for their SEC filings and avoid a U.S. GAAP reconciliation. If they stay on NIF, they must provide a full reconciliation to U.S. GAAP.2U.S. Securities and Exchange Commission. Foreign Private Issuers – Financial Reporting Manual That pressure has pushed many of Mexico’s largest multinationals toward IFRS for consolidated reporting, while their domestic subsidiaries continue filing under NIF locally.
Inflation Accounting: The Biggest Difference
All three frameworks acknowledge that inflation distorts historical-cost financial statements. They disagree sharply on when to do something about it.
NIF B-10 and the 26% Trigger
Under NIF B-10, “Effects of Inflation,” Mexico treats an economy as inflationary when cumulative inflation over the prior three years reaches or exceeds 26%, which averages roughly 8% per year. Once that threshold is met, companies must restate all non-monetary assets and liabilities (property, equipment, inventory, and stockholders’ equity) to 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 produces a gain or loss on net monetary position, which flows through the income statement. Restated asset values also change depreciation and amortization in later periods, so the effects ripple through profitability for years. When cumulative three-year inflation drops back below 26%, the standard is suspended and companies stop recognizing inflation effects.
IAS 29 and the 100% Bar
IFRS does have an inflation standard, IAS 29 (“Financial Reporting in Hyperinflationary Economies”), but it applies only when cumulative three-year inflation approaches or exceeds 100%. That is nearly four times the NIF threshold. In practice, IAS 29 captures only a handful of economies at any given time (Venezuela and Zimbabwe have been typical examples), while NIF B-10 catches the moderate inflationary periods that are far more common in Mexico’s economic history. U.S. GAAP has no equivalent mechanism for domestic reporting.
Where Mexico Stands Now
Mexico’s cumulative three-year inflation for 2022 through 2024 is approximately 19.7%, based on annual rates of about 7.9% in 2022, 5.5% in 2023, and 4.7% in 2024.3St. Louis Fed – FRED. Inflation, Consumer Prices for Mexico That is below the 26% threshold, so NIF B-10 restatement is currently suspended. Mexican financial statements reviewed in 2026 will not carry inflation adjustments unless the picture changes, but the standard remains on the books and can reactivate if inflation accelerates.
Cash Flow Classification
Where interest and dividends appear in the statement of cash flows is a recurring source of confusion, because the three frameworks each handle it differently.
- Under NIF, interest and dividends received are operating activities, while interest and dividends paid are financing activities.
- Under U.S. GAAP, interest paid and interest and dividends received are all operating; dividends paid are financing.
- IFRS (IAS 7) is the most flexible. Interest paid can be operating or financing. Interest received can be operating or investing. Dividends received can be operating or investing. Dividends paid can be operating or financing.4International 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 under U.S. GAAP to financing under NIF, which makes the NIF filer’s operating cash flow look higher and its financing cash flow look lower. Reclassify before you compare.
Consolidation
NIF B-8 governs consolidated financial statements. Its definition of control tracks IFRS 10 closely and requires three elements: power over the investee’s relevant activities, exposure to variable returns, and a link between the power and those returns.
The differences show at the edges. IFRS 10 explicitly recognizes de facto control, so an investor can be deemed to control an entity with less than 50% of voting shares when 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 the holder exercises significant influence.5Grupo BMV. Diferencias Contables Entre Criterios de la CNBV e IFRS Under IFRS 10, those same entities would likely be consolidated based on the risks-and-benefits analysis. Special purpose entities can also fall inside or outside the consolidation perimeter depending on which framework applies.
Employee Profit Sharing (PTU)
Mexico’s constitution requires employers to distribute 10% of pre-tax profits to employees each year through a program called Participación de los Trabajadores en las Utilidades (PTU). There is no equivalent in IFRS or U.S. GAAP, and international analysts regularly misread the line.
The profit base for PTU is the company’s annual income tax return filed with Mexico’s tax authority (SAT), not NIF-basis accounting profit. 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 of profit to equity holders. A Mexican company’s reported net income will be lower than an otherwise identical company operating in a jurisdiction without mandatory profit sharing, and the gap can be material for labor-intensive businesses.
Financial Statement Presentation
NIF requires the same four primary statements that IFRS and U.S. GAAP users expect: statement of financial position, statement of comprehensive income, statement of cash flows, and statement of changes in stockholders’ equity. The income statement under NIF typically draws a sharper line between operational and non-operational income than many IFRS presentations do. The statement of changes in stockholders’ equity is treated as a full primary statement with granular detail on retained earnings, capital contributions, profit distributions, and other equity movements. Required minimum disclosures on related-party transactions and contingencies also differ in ordering and detail from a typical IFRS annual report.
If You File With the SEC
Mexican companies listed on U.S. exchanges file as foreign private issuers, typically on Form 20-F. For fiscal year 2025, the Form 20-F deadline is April 30, 2026, assuming a December 31 year-end.6Broadridge. 2026 SEC Filing Deadlines and Holidays
Whether a reconciliation is required depends on the primary accounting framework. The SEC accepts financial statements prepared under IFRS as issued by the IASB without any reconciliation to U.S. GAAP.7U.S. Securities and Exchange Commission.

Foreign Private Issuers – Financial Reporting Manual When NIF B-10 is active, unwinding the INPC-based restatement of assets and equity is the largest and most complex adjustment. Even with inflation accounting suspended, cash flow classification, consolidation scope, and PTU treatment still generate reconciling items.
If You Own a Mexican Subsidiary
U.S. parent companies with controlled foreign corporations in Mexico file IRS Form 5471 annually for each Mexican subsidiary. When the subsidiary keeps its books under NIF, the filer indicates this on Item G using Code 03.8Internal Revenue Service. Instructions for Form 5471
Schedule H is where NIF-basis book income gets converted to earnings and profits for U.S. tax purposes. The adjustments required by Treasury regulations must account for every material difference between NIF and U.S. tax accounting principles, including inflation restatement when active, PTU expense, and any differences in depreciation methods or asset carrying values. Peso-denominated transactions also generate foreign currency gain or loss under IRC Section 988, which is generally ordinary for U.S. tax purposes.9Office of the Law Revision Counsel. 26 U.S. Code 988 – Treatment of Certain Foreign Currency Transactions Those currency effects interact with NIF inflation adjustments in ways that can be counterintuitive, so the Mexican accounting team and the U.S. tax advisors need to coordinate closely on the E&P calculation.
