πŸ”† 16th Finance Commission and Federalism Debate

πŸ“ Introduction
βœ… The recommendations of the Sixteenth Finance Commission have raised concerns over India’s fiscal federalism.
βœ… While the Commission increases grants to local bodies, many States fear a decline in their own fiscal autonomy.

πŸ“ Key Recommendations of the Commission
βœ… The States’ share in the divisible tax pool remains at 41%.
βœ… However, the effective share of States may fall from nearly 36% to 32% due to greater use of discretionary transfers.
βœ… The Commission has recommended nearly β‚Ή7.91 lakh crore for rural and urban local bodies during 2026–31.
βœ… Of this, around β‚Ή4.4 lakh crore is for rural local bodies and β‚Ή3.6 lakh crore for urban local bodies.

πŸ“ Why States are Concerned
βœ… The Commission has discontinued revenue deficit grants, which earlier supported fiscally weaker States.
βœ… Several smaller and poorer States may lose resources, especially many northeastern States.
βœ… The shift is from predictable, statutory transfers to discretionary grants and centrally sponsored schemes.
βœ… This may increase the Centre’s influence over States.

πŸ“ Article 275 vs Article 282
βœ… Grants under Article 275 are statutory and meant to support States based on need, especially tribal and special area States.
βœ… Grants under Article 282 are discretionary and can be tied to central priorities.
βœ… The Commission is criticised for replacing Article 275-based support with Article 282-type discretionary funding.

πŸ“ Impact on Fiscal Federalism
βœ… Fiscal federalism is based on predictable sharing of resources between Centre and States.
βœ… Greater dependence on discretionary grants may weaken cooperative federalism.
βœ… The recommendations also dilute the constitutional distinction between States and local bodies.
βœ… Panchayats and Municipalities are important, but they constitutionally function under the States through the 73rd and 74th Constitutional Amendments.

πŸ“ Need for a Balanced Approach
βœ… Strengthening local bodies is necessary for grassroots governance.
βœ… But this should not happen at the expense of States’ financial capacity.
βœ… The Centre must ensure a balance between empowering local governments and preserving State autonomy.

πŸ“ Conclusion
βœ… The 16th Finance Commission has attempted to deepen decentralisation, but excessive reliance on discretionary transfers may weaken India’s federal structure.
βœ… Fiscal decentralisation should strengthen both States and local bodies, not create competition between them.

πŸ”Ή Prelims Question
With reference to grants under the Constitution of India, consider the following statements:
1. Article 275 provides statutory grants to States in need.
2. Article 282 grants are discretionary in nature.
3. Panchayats and Municipalities derive their constitutional status from Part IV of the Constitution.

A) 1 and 2 only
B) 2 and 3 only
C) 1 and 3 only
D) 1, 2 and 3

βœ… Answer: A

πŸ”Ή Mains Question
β€œThe recommendations of the Sixteenth Finance Commission reflect a tension between decentralisation and fiscal federalism.” Critically examine.
