Accounting for Foreign-Owned Companies in Mexico
Foreign ownership does not eliminate a company's Mexican accounting and tax responsibilities.
A Mexican company with foreign shareholders generally has the same ongoing accounting, invoicing, tax filing, and reporting requirements that apply to other Mexican businesses.
Foreign companies operating in Mexico without a Mexican legal entity may also have Mexican tax obligations depending on the nature of their activities, income sources, and whether they create a taxable presence in Mexico.
Because cross-border structures can vary considerably, Mextax can review your company's circumstances and help determine which Mexican accounting and tax requirements apply.
CFDI Electronic Invoicing
Mexican businesses use CFDI (Comprobante Fiscal Digital por Internet) electronic invoices to document many business transactions for tax purposes.
Proper invoicing is an important part of maintaining compliant accounting records and supporting income and deductible business expenses.
Mextax can assist with the issuance and cancellation of CFDIs as part of your accounting services.

Business Expenses and Foreign Suppliers
Companies operating in Mexico often purchase software, professional services, consulting, advertising, equipment, or other products and services from suppliers in the United States, Canada, and other countries.
Whether a foreign expense can be deducted in Mexico depends on the nature of the expense, the supporting documentation, payment method, and other applicable Mexican tax requirements.
