Mexico tax update: Nearshoring, audits, and treaty twists

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Adriana Rodriguez, a PwC international tax partner based in Mexico City, for a discussion recorded at PwC’s International Tax Conference. Doug and Adriana discuss the core features of Mexico’s corporate tax system, including corporate income tax, withholding taxes, VAT, inflation adjustments, CFC rules, capital gains planning, and the impact of the multilateral instrument on treaty access.
