Overview
Mexico is the most popular destination for American expats, and many start businesses there — restaurants, real estate companies, consulting firms, and e-commerce operations. If you own 10% or more of a Mexican corporation, you likely have CFC reporting obligations via Form 5471. This guide explains how Mexican corporate structures interact with US CFC, GILTI, and Subpart F rules.
Country-Specific Guidance
Mexican corporations (Sociedad Anónima, S. de R.L., S.A.P.I.) are foreign corporations for US tax purposes. If US persons collectively own more than 50% and each owns at least 10%, the corporation is a CFC.
Mexico has a Totalization Agreement with the US, which may exempt you from US self-employment tax if you pay into IMSS. However, the Totalization Agreement does not affect CFC or GILTI rules.
Mexican corporate tax rates (30% federal) are lower than US rates, which means GILTI inclusions are common for profitable Mexican CFCs.
If your Mexican corporation provides services to US clients, the income may be foreign base company services income under Subpart F, triggering current inclusion even if no distributions are made.
Mexican real estate held through a corporation creates CFC status if US ownership thresholds are met. Rental income may be passive income subject to Subpart F.
Common Mistakes
Assuming a Mexican LLC (S. de R.L.) is treated as a disregarded entity for US tax — it may be, but only if no election is made and it has a single owner. Multiple-member S. de R.L.s are often partnerships or corporations.
Failing to file Form 5471 for a profitable Mexican corporation because no distributions were made.
Ignoring GILTI because the corporation pays Mexican tax — GILTI applies to net tested income, not taxable income.
Not attributing stock owned by a Mexican spouse or family members when calculating CFC status.
Filing Tips
Obtain Mexican financial statements and translate them to USD using the appropriate exchange rate method (year-end rate for the balance sheet, average rate for the income statement).
Calculate QBAI (Qualified Business Asset Investment) carefully — Mexican real estate and equipment count, but intangibles do not.
Consider a Section 962 election if you are an individual shareholder to reduce GILTI tax rate.
File Form 5471 with your Form 1040 by the extended due date. The $10,000 penalty applies even if the corporation had no income.
Frequently Asked Questions
Does my Mexican corporation need to file US taxes?
The corporation itself does not file a US return, but you as a US shareholder must file Form 5471 to report the corporation's income, balance sheet, and your share of Subpart F and GILTI. The corporation may also need to register for US tax purposes if it conducts business in the US.
Can I avoid GILTI by paying myself a salary?
Paying yourself a reasonable salary from the Mexican corporation reduces the corporation's net tested income, which reduces GILTI. However, the salary is taxable to you as earned income. The optimal balance depends on your total income, FEIE eligibility, and Mexican tax rates.
What if my Mexican corporation is inactive?
Even inactive corporations may require Form 5471 if you meet the ownership thresholds. However, inactive corporations with no income generally have no Subpart F or GILTI inclusions. You still must file the form to avoid the $10,000 penalty.
