Thought Leadership

In 2025, Alfonso contributed to an opinion piece with LexLatin titled: “Mexico’s Supreme Court Reviews Virtual Return in IMMEX Transactions: Should VAT Be Paid Twice?” He argued that the virtual return legal fiction should be applied consistently, such that if goods are deemed returned abroad, their sale must also be treated as occurring outside Mexico, warning that a contrary approach could lead to tax distortions and potential double VAT exposure.
