Felipe Caldron, Mexico's new President, addressed one of Mexico's biggest problems low tax revenue by getting passed through the legislature a tax bill that will increase tax revenues from 11% of gross domestic product to 13.5 % of GDP. This will be done by a corporate tax that taxes sales rather than profits starting at 16.5% in 2008 and rising to 17.5% in 2010. The original proposal Calderon requested would have taken this to 19%. The bill cuts taxes on Pemex which will give it an additional $3 billion a year as it is falling behind in new reserves added from exploration and drilling that would replace ones being depleted leading to a decline in output. And the tax bill imposes a tax of 2.5% on cash deposits above $2200 to attempt to collect some taxes from the underground economy which employs about a quarter of the workforce. In addition it imposes a gasoline tax of 5.5% that will go to the state governors for local spending needs. The deal was negotiated by giving the opposition reforms in the electoral process including replacing all commissioners of the Federal Election Institute, and bans radio and television advertising for candidates. Calderon wanted to increase the taxe revenue to 14% of GDP, this would increase it to 13.5%. Considering the previous administrations failure to get any legislation through Congress while Pemex production slipped, and tax revenues were some of the lowest in the world due to widespread evasion (see a similiar problem and tax reforms in the Philippines recently), this is a breakthrough. But Pemex has to turn the corner, and lags way behind Petrobras in Brazil in terms of progress in exploration and new reserves. Revenues from the oil company largely help fund state spending in Mexico. However reforms that free up the state energy sector as Brazil has done (see the recent article on Petrobras in wsj ) some years back are still for the future. How much will this help. Its a modest beginning from a low point under the Vicent Fox administration. The additional $10 billion it generates next year will go to fill the gap in declining tax revenues from state oil company Pemex, and rising health and pension committments of the state....
