Provincial Tax Weaknesses Masked by General Sales Tax Reliance
In the fiscal year 2025-26, provincial tax collections in Pakistan were heavily influenced by the General Sales Tax (GST) on services, which served as the primary revenue driver. However, a deeper analysis reveals significant disparities in tax capacity and revenue mobilization across provinces, indicating weaknesses beyond GST collection. Punjab, Balochistan, Khyber Pakhtunkhwa, and Sindh all showed substantial reliance on GST, with its share ranging from 56.7% in Sindh to 69.6% in Punjab. Despite a higher GST percentage, Sindh's overall tax collection was the highest at Rs608 billion, largely due to its unique structural advantage from port-based Infrastructure Development Cess (IDC) on imports, totaling Rs180 billion. This maritime gateway position allows Sindh to benefit from trade-related revenues, diversifying its tax base more effectively than inland provinces.
However, even in Sindh, collections from property transfers (Rs1 billion), stamp duties (Rs32 billion), and motor vehicles (Rs25 billion) remain modest, suggesting administrative shortcomings and undervaluation. Punjab, while more dependent on GST, demonstrated stronger performance in conventional provincial taxes like property transfer tax (Rs27 billion), stamp duties (Rs54 billion), and motor vehicle taxes (Rs43 billion), indicating a broader tax effort and better administrative capacity. Khyber Pakhtunkhwa faced fiscal challenges with low IDC collections (Rs7 billion) due to border closures and underperformance in property and other provincial taxes, making GST on services its main revenue source. Balochistan also exhibited a narrow revenue base, with GST and IDC being dominant, and limited contributions from property, stamp duty, and land revenue. Across all provinces, the GST on services, despite improvements, remains heavily dependent on the telecommunications sector, and property tax collections are generally weak, presenting significant untapped revenue potential.
The reliance on GST, particularly from the telecommunications sector, highlights a systemic vulnerability in Pakistan's provincial revenue generation. While reforms have broadened the tax base for services, the underlying administrative capacity for collecting other provincial taxes appears underdeveloped across most regions. Provinces like Sindh benefit from unique trade-related revenue streams, but this geographic advantage masks the broader challenge of mobilizing taxes from domestic economic activities such as property and wealth. Punjab's comparatively stronger performance in conventional taxes suggests that administrative efficiency and broader tax effort are achievable. Future fiscal stability will likely depend on harmonizing legislation and collection mechanisms for non-GST provincial taxes, alongside enhanced enforcement and compliance, to reduce dependence on a few key sectors and geographic advantages. The significant gap between declared and estimated agricultural income also points to a major, underutilized revenue source that could be tapped through improved tax administration and policy.
