Maquiladora Safe Harbor (6.9% / 6.5%) & Shelter vs. Standalone IMMEX Calculator
Interactive financial model for US CFOs and tax directors: calculate Mexican Maquiladora Safe Harbor income tax (Article 182 LISR: 6.9% on assets vs. 6.5% on costs) and compare 3-year Shelter vs. Standalone IMMEX operating costs.
Use this interactive CFO model to run two Mexican manufacturing scenario calculations side by side:
- Article 182 LISR Maquiladora Safe Harbor Tax Test: Compares 6.9% of Total Operating Assets (including US-consigned machinery and consigned inventory) against 6.5% of Total Mexican Operating Costs to calculate your illustrative taxable profit and 30% Mexican corporate income tax (ISR).
- Shelter vs. Standalone IMMEX 3-Year Scenario Analysis: Compares the recurring headcount-based Shelter fee against your user-defined internal G&A cost, setup expenses, and Year-1 VAT financing or Rule 7.4.1 bond parameters for a standalone Mexican subsidiary.
