ISLAMABAD (AFP) - Pakistan is defying mounting Western pressure to end a giant tax dodge with fewer and fewer people contributing to government coffers, spelling dire consequences for a sagging economy. Barely one percent of the population pays at all, as a corrupt bureaucracy safeguards entrenched interests and guards private wealth, but starves energy, health and education of desperately needed funds. Less than 10 percent of GDP comes from tax revenue - one of the lowest global rates and worse than in much of Africa, say economists. Federal Board of Revenue (FBR) spokesman Asrar Rauf said 1.9 million people paid tax in 2010, less than the year before, despite 3.2 million being registered to pay - itself a drop in the ocean of a population of 180 million. As a result, Pakistans fiscal deficit widened from 5.3 percent to 6.3 percent of GDP in 2010, the Asian Development Bank said this month, knocking 2011 growth figures to 2.5 percent and predictions for 2012 to 3.2 percent. Tax reform has come to nothing, not least because of political stalemate in the hamstrung parliament and a government coalition threatened with collapse by walk-outs. The IMF last May halted a $11.3 billion assistance package over a lack of progress on reforms, principally on tax. And despite a flurry of meetings, no new loan has been agreed in the run-up to the IMF and World Banks Spring meetings. An IMF review mission is due to visit on May 8. Consensus is building, we have almost reached agreement (on reform), one government official told AFP, but gave no details. Under pressure, President Asif Ali Zardari pushed through a short-term 15 percent flood surcharge on income tax and a 2.5 percent special excise duty in March, but it is uncertain whether they will survive the next budget in June. Government suggestions of raising revenue by reforming a general sales tax ran into walk-outs from politicians who said it unfairly hits the poor. What would really work, say analysts, would be scrapping exemptions that serve entrenched interests, such as a 50 percent tax discount on sugar and a gate on taxing agricultural income that largely exempts wealthy feudal landowners. But stalemate and vested interests have made that impossible. Theres talk of early elections. One has a brittle coalition. A lot of the reform areas that need to be dealt with have very well entrenched and powerful lobbies that are making the case against it, said a finance ministry official. As it is, the tiny minority who contribute say they carry a disproportionate tax burden, for which they get nothing in return. Pakistan suffers from an awful energy crisis, yet government spending on electricity subsidies last year reached just under one percent of GDP, health spending 0.5 percent and education two percent, said the finance ministry. According to a 2009 study by the Pakistan Institute of Legislative Development and Transparency, the average member of parliament was worth $900,000 and the wealthiest $37 million. Those figures stand against estimates that a quarter of the population lives below the poverty line and that GDP per capita stands at $2,400.
