The recent 2G-controversy and the related debate over the role of the PAC as opposed to the JPC also raises a broader Issue regarding the general scrutiny of government finances by Parliament. Oversight of the government’s finances involves the scrutiny of the government’s financial proposals and policies. The Indian Constitution vests this power with the Parliament by providing that (a) taxes cannot be imposed or collected without the authority of law, and (b) expenditure cannot be incurred without the authorisation of the legislature. The Indian Parliament exercises financial oversight over the government budget in two stages: (1) at the time of presentation of the annual budget, and (2) reviewing the government’s budget implementation efforts through the year. The Parliament scrutinises the annual budget (a) on the floor of the House, and (b) by the departmentally related standing committees. Scrutiny on the floor of the House The main scrutiny of the budget in the Lok Sabha takes place through: (a) General discussion and voting: The general discussion on the Budget is held on a day subsequent to the presentation of the Budget by the Finance Minister. Discussion at this stage is confined to the general examination of the Budget and policies of taxation expressed during the budget speech. (b) Discussion on Demand for Grants: The general discussion is followed by a discussion on the Demand for Grants of different ministries. A certain number of days or hours are allocated for the discussion of all the demands. However, not all the demands are discussed within the allotted number of days. The remaining undiscussed demands are disposed of by the Speaker after the agreement of the House. This process is known as the ‘Guillotine’. Figure 1 shows the number of Demands discussed and guillotined over the last five years. It shows that nearly 90% of the Demands are not discussed every year. 
Some Important Budget Documents Annual Financial Statement – Statement of the estimated receipts and expenditure of the government. Demand for Grants –Expenditure required to be voted by the Lok Sabha. A separate Demand is required to be presented for each department of the government. Supplementary Demand for Grants – Presented when (a) authorized amounts are insufficient, or (b) need for additional expenditure has arisen. Finance Bill – Details the imposition of taxes, the rates of taxation, and its regulation. Detailed Demand for Grants – Prepared on the basis of the Demand for Grants. These show further break-up of objects by expenditure, and also actual expenditure in the previous year. For more details see detailed note on Financial Oversight by Parliament here.
In November 2017, the 15th Finance Commission (Chair: Mr N. K. Singh) was constituted to give recommendations on the transfer of resources from the centre to states for the five year period between 2020-25. In recent times, there has been some discussion around the role and mandate of the Commission. In this context, we explain the role of the Finance Commission.
What is the Finance Commission?
The Finance Commission is a constitutional body formed every five years to give suggestions on centre-state financial relations. Each Finance Commission is required to make recommendations on: (i) sharing of central taxes with states, (ii) distribution of central grants to states, (iii) measures to improve the finances of states to supplement the resources of panchayats and municipalities, and (iv) any other matter referred to it.
Composition of transfers: The central taxes devolved to states are untied funds, and states can spend them according to their discretion. Over the years, tax devolved to states has constituted over 80% of the total central transfers to states (Figure 1). The centre also provides grants to states and local bodies which must be used for specified purposes. These grants have ranged between 12% to 19% of the total transfers.
Over the years the core mandate of the Commission has remained unchanged, though it has been given the additional responsibility of examining various issues. For instance, the 12th Finance Commission evaluated the fiscal position of states and offered relief to those that enacted their Fiscal Responsibility and Budget Management laws. The 13th and the 14th Finance Commissionassessed the impact of GST on the economy. The 13th Finance Commission also incentivised states to increase forest cover by providing additional grants.
15th Finance Commission: The 15th Finance Commission constituted in November 2017 will recommend central transfers to states. It has also been mandated to: (i) review the impact of the 14th Finance Commission recommendations on the fiscal position of the centre; (ii) review the debt level of the centre and states, and recommend a roadmap; (iii) study the impact of GST on the economy; and (iv) recommend performance-based incentives for states based on their efforts to control population, promote ease of doing business, and control expenditure on populist measures, among others.
Why is there a need for a Finance Commission?
The Indian federal system allows for the division of power and responsibilities between the centre and states. Correspondingly, the taxation powers are also broadly divided between the centre and states (Table 1). State legislatures may devolve some of their taxation powers to local bodies.
The centre collects majority of the tax revenue as it enjoys scale economies in the collection of certain taxes. States have the responsibility of delivering public goods in their areas due to their proximity to local issues and needs.
Sometimes, this leads to states incurring expenditures higher than the revenue generated by them. Further, due to vast regional disparities some states are unable to raise adequate resources as compared to others. To address these imbalances, the Finance Commission recommends the extent of central funds to be shared with states. Prior to 2000, only revenue income tax and union excise duty on certain goods was shared by the centre with states. A Constitution amendment in 2000 allowed for all central taxes to be shared with states.
Several other federal countries, such as Pakistan, Malaysia, and Australia have similar bodies which recommend the manner in which central funds will be shared with states.
Tax devolution to states
The 14th Finance Commission considerably increased the devolution of taxes from the centre to states from 32% to 42%. The Commission had recommended that tax devolution should be the primary source of transfer of funds to states. This would increase the flow of unconditional transfers and give states more flexibility in their spending.
The share in central taxes is distributed among states based on a formula. Previous Finance Commissions have considered various factors to determine the criteria such as the population and income needs of states, their area and infrastructure, etc. Further, the weightage assigned to each criterion has varied with each Finance Commission.
The criteria used by the 11th to 14thFinance Commissions are given in Table 2, along with the weight assigned to them. State level details of the criteria used by the 14th Finance Commission are given in Table 3.
Grants-in-Aid
Besides the taxes devolved to states, another source of transfers from the centre to states is grants-in-aid. As per the recommendations of the 14th Finance Commission, grants-in-aid constitute 12% of the central transfers to states. The 14th Finance Commission had recommended grants to states for three purposes: (i) disaster relief, (ii) local bodies, and (iii) revenue deficit.
