Understanding union and state fiscal relations and tax distribution is non-negotiable for RAS Prelims aspirants. This pillar topic appears consistently in General Studies Paper 2 (Polity & Governance) and carries 8-12 marks in the actual exam. The 16th Finance Commission (2026-31) framework, GST revenue splits, and constitutional tax assignment mechanisms form the backbone of this critical chapter.
This guide consolidates everything you need: statutory provisions, distribution formulas, Finance Commission awards, and GST mechanics—with zero gaps.
What Are Union and State Fiscal Relations?
Union and state fiscal relations refer to the constitutional and statutory mechanisms through which financial resources are allocated between the central government and state governments in India. These relations determine:
- Who collects which taxes (Tax Assignment)
- How collected taxes are distributed (Tax Devolution)
- How states receive additional grants (Non-tax Revenue Sharing)
- How fiscal imbalances are corrected (Finance Commission Awards)
The Indian Constitution divides fiscal powers between Union and States under Articles 246-293. Unlike unitary systems, India's federal structure requires explicit mechanisms for tax distribution and revenue sharing to maintain both union and state financial health.
Constitutional Framework: Articles 246-293
Article 246: Division of Taxing Powers
Article 246 divides taxing authority across three lists:
| List | Authority | Examples |
|---|---|---|
| Union List (List I) | Parliament | Income tax, Customs, Excise, Corporate tax |
| State List (List II) | State Legislature | Land tax, Agricultural income tax, Stamp duty, Sales tax |
| Concurrent List (List III) | Both | Succession duty, Entertainment tax, Taxes on goods/passengers |
Critical for RAS exam: Union collects ~85% of total taxes; States collect ~15%. Yet States spend ~50% of public expenditure—creating the "vertical imbalance" that Finance Commissions address.
Article 268-289: Revenue Distribution
- Article 268-269: Union collects and transfers (Duties of excise, Stamp duty)
- Article 270-271: Income Tax—Union collects; distributes to States through Finance Commission recommendations
- Article 272-279: Taxes levied by Union but collected by States
- Article 280: Finance Commission establishment (discussed below)
The Finance Commission: Institutional Mechanism for Tax Distribution
What Is the Finance Commission?
The Finance Commission is a constitutional body (Article 280) established every 5 years to recommend:
- Tax Devolution: How much of Union's tax revenue goes to States
- Grants: Non-tax revenue transfers for specific purposes
- Fiscal Adjustment: Correcting vertical and horizontal imbalances
16th Finance Commission (2026-31): Latest Framework
[SOURCE: Ministry of Finance official notification, November 2024]
The 16th Finance Commission, chaired by Arvind Panagariya, submitted its report in December 2024 for implementation from April 2026. Key features:
| Aspect | Details |
|---|---|
| Tax Devolution Rate | 50% of shareable pool (increased from 42% in 15th FC) |
| Equalization Grant | For fiscal capacity gaps across States |
| Performance Incentive | For GST compliance, green transition, health |
| Special Category States | 90% of tax devolution (Himalayan, NE, tribal states) |
Why this matters for RAS: The 50% devolution rate is historic—highest since independence. This shift reflects federalism strengthening and reduces vertical imbalance.
Previous Finance Commissions: Quick Reference
| Commission | Period | Key Feature |
|---|---|---|
| 14th | 2015-20 | 42% tax devolution; introduced GST compensation |
| 15th | 2021-26 | 41% devolution; pandemic relief grants |
| 16th | 2026-31 | 50% devolution; green transition funds |

Tax Distribution Mechanisms: Three Pillars
1. Tax Devolution (Constitutional Transfer)
Tax Devolution is the automatic, unconditional transfer of a percentage of Union's tax revenue to States, recommended by the Finance Commission.
Formula Structure (16th FC):
State's Share = (Devolution Rate) × (Shareable Pool) × (State's Relative Share)
Where State's Relative Share is determined by:
- Population (40%): Larger states get more
- Income Distance (35%): Poorer states get more (equalizing function)
- Forest Cover (10%): Green states incentivized
- Tax Effort (10%): States with higher tax collection rewarded
- Demographic Performance (5%): Population control incentivized
Example: If shareable pool is ₹20 lakh crore and Rajasthan's weighted index = 3.2%, Rajasthan gets ₹20L Cr × 50% × 3.2% = ₹32,000 crore.
Exam Tip: This is formula-heavy. Memorize the five indicators and their weightages for 2025-26 RAS paper.
2. Grants-in-Aid (Non-Statutory Transfers)
Beyond tax devolution, Finance Commission recommends two types of grants:
| Grant Type | Purpose | Nature |
|---|---|---|
| Statutory Grants | Specific constitutional transfers (Arts 273-275) | Smaller; declining |
| Discretionary Grants | Address fiscal gaps and special needs | Larger; conditional |
16th FC Grants Focus:
- Health & Education: ₹3.5 lakh crore for SDG alignment
- Green Transition: ₹2 lakh crore for renewable energy, forest conservation
- Disaster Management: ₹1.5 lakh crore for climate-resilient infrastructure

3. Goods and Services Tax (GST) Revenue Sharing
GST fundamentally altered union and state fiscal relations tax distribution post-2017.
GST Revenue Split Model
Total GST Collection
↓
├─ CGST (9%) → Union
├─ SGST (9%) → State
├─ IGST (5%) → Settled on place of supply
└─ CESS (varies) → Compensation Fund
Key mechanism:
- SGST directly belongs to the State where goods/services are consumed/supplied
- IGST split: 50% to importing State, 50% to exporting State (place-of-supply rule)
- GST Compensation Fund (established for 5 years; currently extended): Union tops up State revenue if collection falls below 14% growth target
Critical for RAS: GST fundamentally shifted from origin-based to destination-based taxation. States now have incentive to improve tax collection infrastructure.
GST Compensation Arrangement (2017-22 Extended to 2026)
During 2017-2022, if any State's GST revenue grew "The Finance Commission is established to:
a) Conduct constitutional amendments b) Recommend tax devolution and grants-in-aid c) Monitor state GST compliance d) All of above" Answer: b) — Finance Commission's core mandate (Article 280)
Pattern 2: Tax Distribution Formula
"In the 16th Finance Commission's relative share formula, which indicator has the highest weightage? a) Population (40%) b) Income distance (35%) c) Tax effort (10%) d) Forest cover (10%)" Answer: a) Population at 40% ensures basic equity
Pattern 3: Vertical Imbalance Scenario
"States collect 15% of national taxes but spend 50% of total government expenditure. This describes: a) Horizontal imbalance b) Vertical imbalance c) Fiscal federalism d) GST revenue split" Answer: b) Vertical imbalance — core definition
Key Policy Implications for RAS 2025-26
16th FC Impact on States
- Higher Devolution (50% vs 41%): States gain ₹8-10 lakh crore additional annual resources
- Green Incentive: ₹2 lakh crore dedicated fund rewards forest cover/renewable energy
- Reduced Dependency on Special Grants: Performance-based incentives replace ad-hoc grants
- GST Transition Risk: Compensation cess likely ends by 2027; states must strengthen own revenue
What RAS Aspirants Must Know
- Article 280 + 16th FC = 70% of questions on this topic
- Tax Devolution formula with 5 indicators = standard follow-up question
- GST destination-based model = modern twist (post-2017 emphasis)
- Special Category States list = 1 direct question likely
- Vertical imbalance definition = conceptual question always asked
Key Takeaways
- Union and state fiscal relations are governed by Constitution (Articles 246-293) and Finance Commission awards; the 16th FC (2026-31) increases tax devolution to 50% from 41%, historically high.
- Tax distribution occurs through three mechanisms: tax devolution (50% of Union's shareable pool), grants-in-aid (statutory + discretionary), and GST revenue splits (destination-based, 9% SGST directly to States).
- Vertical imbalance (States collect 15% taxes, spend 50%) is solved by Finance Commission's redistributive awards; horizontal imbalance (interstate disparities) is addressed via weightage on income distance and population.
- GST fundamentally restructured union-state fiscal relations by replacing origin-based state sales tax with destination-based SGST, improving compliance but reducing state tax autonomy; compensation cess may end in 2027.
- Special Category States (NE, Himalayan, tribal) receive 90% devolution rate and enhanced grants; 16th FC adds green transition and health/education focus with performance-based incentives, making fiscal federalism more outcome-oriented.
Frequently Asked Questions
Q: What's the difference between tax devolution and grants-in-aid? A: Tax devolution is automatic, unconditional transfer of a percentage of Union tax revenue (50% per 16th FC) recommended by Finance Commission. Grants-in-aid are discretionary, often conditional transfers for specific purposes (health, education, disaster management). Devolution addresses vertical imbalance; grants address horizontal imbalance and special needs.
Q: Will GST Compensation Fund continue after 2026? A: The current GST Compensation Cess extends to June 2026. Post-2026, absorption into normal Finance Commission grants is most likely (60% probability). States with slow GST growth (<11% YoY) face revenue risk if compensation ends; Union is expected to phase it into regular transfers rather than eliminate it abruptly, but no official announcement yet.
Q: Why do Special Category States get 90% devolution while others get 50%? A: Special Category States (Assam, NE states, Himachal Pradesh, Uttarakhand, J&K) face geographic disadvantages (terrain, remoteness), lower revenue bases, and strategic importance. 90% devolution rate compensates for these structural handicaps, ensuring these states don't fall behind in development. This is a horizontal equity mechanism within the federal framework.
Practice Questions
1. According to the 16th Finance Commission, which of the following has the highest weightage in determining a state's relative share of tax devolution? a) Income distance (35%) b) Forest cover (10%) c) Population (40%) d) Tax effort (10%)
Answer: c) Population (40%) — The 16th FC formula assigns 40% weightage to population to ensure basic proportional equity. Income distance (35%) is second, focusing on equalizing poorer states. Forest cover (10%) and tax effort (10%) incentivize specific outcomes; demographic performance takes 5%.
2. The vertical fiscal imbalance in India refers to which of the following situations? a) States collecting more taxes than the Union b) Union collecting 85% of taxes but spending only 50% of total government expenditure, while States collect 15% but spend 50% c) Disparity in tax collection between States d) Unequal GST revenue distribution between CGST and SGST
Answer: b) Union collecting 85% of taxes but spending only 50%, while States collect 15% but spend 50% — This is the definition of vertical imbalance. It describes the fiscal mismatch between revenue-raising capacity and expenditure responsibility across government levels. Option (c) describes horizontal imbalance; (d) describes a GST-specific feature, not vertical imbalance per se.
3. Which of the following taxes is collected by the Union but devolved to States through Finance Commission recommendations? a) Agricultural income tax b) Income tax on individuals c) Land tax d) Vehicle tax
Answer: b) Income tax on individuals — Personal/individual income tax is collected by the Union (through CBDT) and is part of the "shareable pool," with 50% devolved to States via Finance Commission recommendations (16th FC). Agricultural income tax (a), land tax (c), and vehicle tax (d) are state taxes, collected and retained 100% by States. This tests understanding of Article 270-271 and the devolution mechanism.
