Copyright 1996 InterAm Database National Law Center for Inter-American Free Trade April 10, 1992 Completion of U.S.A. - Mexico tax treaty delayed by withholding disagreement TEXT: It has been reported that negotiations for the new U.S.A. - Mexico tax treaty have stalled over a disagreement about the rate of withholding tax applicable to cross-border dividends. Mexico is said to be insisting on a zero withholding rate for both intercompany dividends and portfolio dividends, while the U.S. position, based on the U.S. Model Treaty, is 5% for intercompany dividends and 15% for portfolio dividends. The U.S.A. is said to be willing to reach a compromise on the portfolio rate, but is concerned that Congress would not accept a zero rate overall. The Mexican position is that the rates it is offering on interest, royalties and dividends must be accepted as a package, since it believes that it is making significant revenue concessions with respect to the rate on interest. Two other areas of dispute are reported to be whether to make the Mexican asset tax expressly creditable under the treaty and whether or not to include in the treaty a compulsory arbitration clause.
