Committee headed by the Chief Economic Adviser Dr. Arvind Subramanian on Possible Tax rates under GST submits its Report to the Finance Minister.

On the Revenue Neutral Rate (RNR), the Committee recommends the same in the range between 15 percent and 15.5 percent (Centre and states combined) with a preference for the lower end of that range based on the analysis made in the Report 


Following are the highlights of the Executive Summary of the Report submitted:


Getting the design of the GST right is, therefore, critical. Specifically, the GST should aim at tax rates that protect revenue, simplify administration, encourage compliance, avoid adding to inflationary pressures, and keep India in the range of countries with reasonable levels of indirect taxes.


The term revenue neutral rate (RNR) will refer to that single rate, which preserves revenue at desired (current) levels.


Against this background, the Committee drew a few important conclusions.


  • Because identifying the exact RNR depends on a number of assumptions and imponderables; because, therefore, this task is as much soft judgement as hard science; and finally also because the prerogative of deciding the precise numbers will be that of the future GST Council, this Committee has chosen to recommend a range for the RNR rather than a specific rate. For the same reason, the Committee has decided to recommend not one but a few conditional rate structures that depend on policy choices made on exemptions, and the taxation of certain commodities such as precious metals.


The summary of recommended options is provided in the table below.

Summary of Recommended Rate Options (in percent)
RNR Rate on precious metals “Low” rate (goods) “Standard” rate

(goods and services)

“High/Demerit” rateor Non-GST excise (goods)
15.0     6   12   16.9     40
15.0     4   12   17.3     40
15.0     2   12   17.7     40
15.5     6   12   18.0     40
15.5     4   12   18.4     40
15.5     2   12   18.9     40


All rates are the sum of rates at center and states


  • On the RNR, the Committee’s view is that the range should between 15 percent and 15.5 percent (Centre and states combined) but with a preference for the lower end of that range based on the analysis in this report.
  • On structure, in line with growing international practice and with a view to facilitating compliance and administration, India should strive toward a one-rate structure as the medium-term goal.
  • Meanwhile, the Committee recommends a two-rate structure. In order to ensure that the standard rate is kept close to the RNR, the maximum possible tax base should be taxed at the standard rate. The Committee would recommend that lower rates be kept around 12 per cent (Centre plus states) with standard rates varying between 17 and 18 per cent.
  • It is now growing international practice to levy sin/demerit rates—in the form of excises outside the scope of the GST–on goods and services that create negative externalities for the economy. As currently envisaged, such demerit rates—other than for alcohol and petroleum (for the states) and tobacco and petroleum (for the Centre)—will have to be provided for within the structure of the GST. The foregone flexibility for the center and the states is balanced by the greater scrutiny that will be required because such taxes have to be done within the GST context and hence subject to discussions in the GST Council. Accordingly, the Committee recommends that this sin/demerit rate befixed at about 40 percent (Centre plus states) and apply to luxury cars, aerated beverages, paan masala, and tobacco and tobacco products (for the states).
  • The Committee’s recommendations on rates summarized in the table above are all national rates, comprising the sum of central and state GST rates. How these combined rates are allocated between the center and states will be determined by the GST Council. This allocation must reflect the revenue requirements of the Centre and states so that revenues are protected. For example, a standard rate of 17% would lead to rates at the Centre and states of say 8 percent and 9 percent, respectively. The Committee considers that there are sound reasons not to provide for an administration-complicating “band” of rates, especially given the considerable flexibility and autonomy that states will preserve under the GST (including the ability to tax petroleum, alcohol, and other goods and services).
