The rule

1. Who must register and when. The RNIE must register: Mexican companies in which foreign investment, Mexicans with another nationality domiciled abroad, or neutral investment take part, including through a trust; foreign individuals or companies, and Mexicans with another nationality domiciled abroad, that habitually carry out commercial acts in Mexico; and trusts of shares, real estate or neutral investment that give rights to foreign investment. The company or person registers; for trusts, the trustee bank does. Registration is due within 40 business days from incorporation or entry of the foreign investment, from formalization of the foreign company's documents, or from creation of the trust or grant of beneficiary rights to the foreign investor. Foreign individuals and companies register within 40 business days after they start trading habitually.
Cost to do it: LFD art. 72 sets no duty for RNIE filings; the cost is preparing the forms, usually done by the company's lawyers or accountants.
Example: A Mexican company incorporated on 2 November 2026 with a Chilean parent must file its RNIE registration within 40 business days of that date. / No government fee in either currency.Ley de Inversión Extranjera (Foreign Investment Law, LIE), DOF 27 December 1993, last reform DOF 27 May 2024; Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, LIE art. 32 (fractions reformed DOF 24 December 1996 and 23 January 1998); RLIE art. 37, 1998-01-23 official text · verified 2026-10-26

2. What the registration contains. For companies and foreign traders: name, domicile, incorporation date and main activity; the legal representative and persons authorized for notices; name, nationality, immigration status where relevant, domicile and percentage of each foreign investor; subscribed and paid capital; and the expected start of operations and approximate total investment with its schedule. For trusts: the trustee, settlors and foreign beneficiaries, the trust's date, purpose and term, and a description, value, use and location of the trust assets. Any change must be notified as the regulation provides, and the RNIE may ask for clarifications.
Cost to do it: No duty; internal time to collect shareholder and capital data.
Example: The registration lists the Chilean parent's 99 percent stake, a Mexican individual's 1 percent, MXN 50,000 of paid capital and the investment schedule for the first plant. / MXN 50,000 is about USD 2,702.Ley de Inversión Extranjera (Foreign Investment Law, LIE), DOF 27 December 1993, last reform DOF 27 May 2024, Art. 33 (fraction I, d) reformed DOF 25 May 2011), 1993-12-27 official text · verified 2026-10-26

3. The registry is confidential. The RNIE is not public. The Ministry of Economy may not give third parties the information in the files of a registered person; only those who prove they represent the registered person may consult a file, in person at the registry.
Cost to do it: No fee.
Example: A competitor cannot obtain a rival's RNIE filings; a buyer in due diligence must ask the target for its filing receipts. / Not applicable.Ley de Inversión Extranjera (Foreign Investment Law, LIE), DOF 27 December 1993, last reform DOF 27 May 2024; Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, LIE art. 31; RLIE art. 32, 1998-09-08 official text · verified 2026-10-26

4. Annual renewal. Registered companies and foreign traders must renew their registration every year by filing the economic and financial questionnaire with corporate, accounting, financial, employment, production and activity data for the prior fiscal year. The window follows the first letter of the name: A to J during April, K to Z during May. Filings made before the assigned month are treated as filed on the first business day of that month. The questionnaire covers only the last five fiscal years and is required only above the amount the CNIE sets by general resolution.
Cost to do it: No duty; missing the renewal is fined 30 to 100 UMA (LIE art. 38, fraction IV), MXN 3,519.30 to MXN 11,731 in 2026.
Example: Andes Componentes S.A. de C.V. files its 2026 questionnaire during April 2027; Zeta Logística S.A. de C.V. files during May 2027. / Fine range about USD 190 to USD 634.Ley de Inversión Extranjera (Foreign Investment Law, LIE), DOF 27 December 1993, last reform DOF 27 May 2024; Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, LIE art. 35; RLIE art. 38, fraction III, and art. 43 (reformed DOF 31 October 2014), 2014-10-31 official text · verified 2026-10-26

5. Quarterly reports. Above the amounts the CNIE sets by general resolution published in the DOF, registered companies and foreign traders must report within 10 business days after each calendar quarter: changes to the registered data (shareholding, capital, representatives); and income and outflows from new contributions or withdrawals that do not affect capital, retention of the year's profits or use of retained earnings, and loans payable or receivable with foreign subsidiaries, the foreign parent, foreign shareholders or foreign group companies, including bonds, notes, deposits and trade credit with maturities over one month, naming the counterparties. Trustee banks update trust data within 40 business days of a change when the investment exceeds the CNIE amount.
Cost to do it: No duty; late or wrong reports are fined 30 to 100 UMA (LIE art. 38, fraction IV).
Example: A subsidiary that borrows from its US parent in August 2026 and exceeds the CNIE quarterly amount reports the loan within 10 business days after 30 September 2026. / Fine range about USD 190 to USD 634 per infraction.Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, Art. 38, fractions I and II, and art. 41 (reformed or added DOF 31 October 2014), 2014-10-31 official text · verified 2026-10-26

6. Filing mechanics and corrections. Filings use the approved formats, in Spanish, with supporting documents, and translations by an expert translator where needed. The stamped copy with filing number and date, marked as filed without obvious errors, serves as the registration, renewal or cancellation certificate. If the authority finds omissions it gives 5 business days to cure them, otherwise the filing is treated as not filed; if it raises no request within 10 business days, the filing is deemed complete. Extensions of up to half of a deadline may be requested in writing before it expires, on special grounds and after paying the duty.
Cost to do it: Extension requests cost MXN 1,007 for the first and MXN 2,015 for later ones in 2026 (LFD art. 72, fraction IX, RMF 2026 Annex 4).
Example: A company that needs more time for a 40 business day registration can ask for up to 20 more business days before the deadline and pay MXN 1,007. / About USD 54 for the first extension.Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, Arts. 33, 34 and 35 (reformed DOF 31 October 2014) and art. 48, 2014-10-31 official text · verified 2026-10-26

7. Notaries police the registry. In incorporations, amendments, transformations, mergers, spin offs, dissolutions and liquidations, and any act involving a person obliged to register, notaries must ask for proof of RNIE registration or of the pending application. If it is not shown, the notary may still authorize the deed but must report the omission to the RNIE within 10 business days. Proof is the receipt of the last annual questionnaire due or, for new registrants, the registration receipt.
Cost to do it: No fee; the practical cost is a delayed closing if receipts cannot be found.
Example: At a capital increase in March 2027, the notary asks for the receipt of the questionnaire filed in 2026 for fiscal year 2025. / Not applicable.Ley de Inversión Extranjera (Foreign Investment Law, LIE), DOF 27 December 1993, last reform DOF 27 May 2024; Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, LIE art. 34; RLIE arts. 44 and 45, 1998-09-08 official text · verified 2026-10-26

8. Cancellation and fines. Registered persons must request cancellation within 40 business days after they stop being obliged to register, for example after foreign shareholders exit. Omission, late compliance or incomplete or incorrect information in registrations, reports or notices is fined 30 to 100 times the daily reference, read as the UMA since 2016; the Ministry hears the party first and weighs gravity, economic capacity, the delay and the value of the operation.
Cost to do it: MXN 3,519.30 to MXN 11,731 per infraction at the 2026 UMA of MXN 117.31.
Example: After a Mexican buyer acquires all foreign held shares on 15 January 2027, the company files its cancellation within 40 business days. / About USD 190 to USD 634.Ley de Inversión Extranjera (Foreign Investment Law, LIE), DOF 27 December 1993, last reform DOF 27 May 2024; Reglamento de la Ley de Inversión Extranjera y del Registro Nacional de Inversiones Extranjeras (RLIE), DOF 8 September 1998, last reform DOF 17 August 2016, LIE art. 38, fraction IV and last paragraphs; RLIE arts. 40 and 42, 1993-12-27 official text · verified 2026-10-26

RNIE calendar for a Mexican subsidiary of a foreign group

Worked example

Northwind Mexico S. de R.L. de C.V. is formed on 2 November 2026 by a US parent with MXN 50,000 (about USD 2,702) of capital.
It registers in the RNIE within 40 business days (LIE art. 32). In January 2027 the parent lends USD 2,000,000 (about MXN 37,005,200) for working capital; if the quarterly flows exceed the CNIE amount, the loan is reported within 10 business days after 31 March 2027 (RLIE art. 38, II).
Because its name starts with N, it files the questionnaire for fiscal year 2026 in May 2027 (RLIE art. 43).
A missed filing would cost MXN 3,519.30 to MXN 11,731 (about USD 190 to USD 634) per infraction (LIE art. 38, IV), and the notary at the next capital increase will ask for the latest receipt (LIE art. 34).

Step by step

1. At incorporation, diarize the 40 business day registration deadline and file the registration form with supporting documents.
2. Keep the stamped receipts; notaries and buyers will ask for them.
3. Each quarter, check capital flows, retained earnings decisions and intercompany loans against the CNIE reporting amounts; file within 10 business days.
4. Each April or May, file the economic and financial questionnaire for the prior fiscal year.
5. On exit of all foreign investors or liquidation, file the cancellation within 40 business days.

Common traps

Mexicans with a second nationality domiciled abroad count for RNIE purposes (LIE art. 32), even if the company has no other foreign shareholders.
Neutral investment also triggers registration (LIE art. 32, fraction I, c).
Loans of more than one month count, including trade credit and notes with group companies (RLIE art. 38, II).
A filing marked as having obvious errors is not a valid certificate (RLIE art. 35).
Thresholds are set by CNIE general resolution; check the current resolution before deciding a report is not required.
