The National Finance Commission distributes tax revenue collected by the federal government among Pakistan's provinces every five years. The most recent NFC Award saw vertical revenue distribution of 80% to provinces and 20% to the federal government. Horizontally, Punjab received the largest share at 57.9% while Sindh, NWFP, and Balochistan received lower shares. Critics argue population alone should not determine distribution and other factors like infrastructure and poverty levels should also be considered to ensure a more equitable division of resources.
