Transfer pricing
Mexico
Mexico has transfer pricing rules. Acceptable transfer pricing methods include the comparable uncontrolled price method, the resale price method, the cost-plus method, the profit-split method, the residual profit-split method and the transactional net-margin method. In certain cases, specific appraisals are used. Transactions between related parties are subject to greater scrutiny, and there are several informative tax returns on related parties transaction that must be filed. It may be possible to reach transfer pricing agreements in advance with Hacienda. These agreements may apply for a period of up to 5 years, such agreements are not available for Maquila regime companies since 2022.
Beginning in 2016, certain Mexican taxpayers must file additional transfer pricing documentation, including a Master File and Country-by-Country reports, as recommended by Action 13 of the Base Erosion and Profit Shifting report.
The 2022 reform included changes in definitions to increase the scope of transfer pricing adjustments; to compare the financial information of similar companies (single year/same year); to include detailed information for capital adjustments; to expand function, risk and asset analysis of the foreign entity; and to clarify the use of the interquartile range.
Interest deductibility rules
Interest deductions may be disallowed under 2 scenarios: in case of the thin cap rule and in case of a net interest in excess of 30 percent of the EBITDA tax.
If the debt-to-equity ratio exceeds 3 to 1 on loans with foreign related parties, the interest triggered by the exceeding proportion of the loan are non-deductible under the thin cap rule. There are some exceptions to these rules, based on the type of activities that would be funded in Mexico.
Net interest against a Mexican taxpayer that exceeds 30 percent of a taxable EBITDA will not be deductible. The first MXP20 million (USD1 million) of annual interest per group is fully deductible. A carry-forward of the non-deductible interest is provided for up to 10 years.
