Similar to most countries, the objectives of the taxation system in Pakistan are not well-defined. Historically, the primary objective has been resource generation for the government. The taxation system has simultaneously addressed the secondary objectives of promoting area/sectorspecific economic activities, discouraging undesired imports/production, encouraging savings and investment. These objectives were met through a variety of tax concessions and exemptions, rebates and credits, differentiated tax rates and tariffs. The revenue shortfalls/leakages resulting from preferential tax treatment of the desired activities were offset through appropriate changes in various fiscal instruments, e.g. high tax rates and tariffs, regulatory duties, extended withholding and presumptive taxes, excise duties on services, and many more. These measures, in turn, complicated the taxation system and adversely affected the equity, neutrality and progressivity thereof.
