Tax Reforms

India’s tax-GDP ratio may be too high

Note4Students

From UPSC perspective, the following things are important :

Prelims level : Tax buoyancy

Mains level : Paper 3- Tax-to-GDP ratio

Context

What the data conclusively show is that the debate on the Indian economy should shift away from simplistic notions (borrowed from the West?) of the tax-GDP ratio being low in India.

India’s low tax-to-GDP ratio

  • One of the stylised beliefs in India, and amongst some leading economic commentators both in India and abroad, is that our tax/GDP ratio is lower than what it “should” be.
  • This low tax-to-GDP ratio is blamed for a lower rate of investment, a higher fiscal deficit, and lower GDP growth — and all because the tax ratio is too low.
  • There can be reasonable doubts about the presumed links.
  • There are three important fiscal variables in the economy — taxes, fiscal deficit, and debt.
  • They are inter-related — lower tax revenue means higher fiscal deficit, for the same level of expenditures, and higher deficit means higher debt.
  • All three, directly or indirectly, are assumed to affect growth and/or inflation.

Analysing India’s tax-to-GDP ratio

  • Two common observations on tax-to-GDP for India — first, it is low at around 10-11 per cent of GDP and it has stayed at close to that level for the last 20 years.
  • In 2019, it hit a decade low of 10 per cent of GDP, the same as in 2014.
  • Second, in comparison with our peers, it is much lower.
  • Hence, logic dictates that we should strive to increase it.
  • But which country should we compare India with?

Issues with comparing tax-to-GDP with other countries

  • A common observation is to look at the tax-GDP ratio in G20 countries.
  • Function of average level of per capita income: This is the beginning of a set of misinterpretations committed either knowingly, or unknowingly.
  • Because simple logic dictates that tax collected is a function of the average level of per capita income.
  • Per capita income in the G20 varies from around $2,100 (India) to around $65,000 (US).
  • The 10-11 per cent figure for India is the tax/GDP ratio for taxes administered at the central level.
  • Challenges in data collection: Taxes in India, as in many other large, especially federal, countries, are collected at both a federal and state level.
  • And many economies have local (municipal) taxes as well. The tax collected is the sum of all these taxes.
  • Until now, collecting such disaggregated data for a large set of countries was challenging.
  • However, in a recent web publication, the IMF on their World Revenue Longitudinal Data set has published such data for all countries, from 1990-2019.
  • In this pre-pandemic year, among G20 economies, India’s tax-GDP (Xtax) ratio of 16.7 per cent was higher than that of China (15.9 per cent), Mexico (14.1 per cent), Indonesia (11.0 per cent), Saudi Arabia (5.9 per cent) and Turkey (15.9 per cent).
  • A more informative indicator of whether a country is taxing too much or too little in comparison with others is to look at the tax-GDP ratio adjusted for PPP per capita income.
  • Prediction via a simple regression of tax-to-GDP on log PPP per capita GDP can yield one estimate of the tax gap — the difference between actual and actual adjusted for level of income.
  • The world average tax gap is -1.3 per cent; India is +1.2 per cent for the nine years 2011-2019.
  • So, India’s tax GDP ratio averages 2.5 percentage points more than an average economy.
  • For every year for which data are available 1990-2019, India has had a positive tax gap — there is little evidence that a higher tax/GDP ratio helps growth.

How corporate tax cut helped India

  • Corporate tax cut 2019: For years, the advocacy in India was to increase revenue from corporate tax which is one of three major components of tax revenue, the other being income and indirect taxes.
  • In September 2019, Finance Minister going well against Indian established conventional wisdom, lowered the corporate tax rate by around 10 percentage points.
  • Avoiding triple whammy: Opponents said that empirical evidence around the world (for example, the US) meant that if tax rates were lowered, revenues would decline, the fisc would increase, as would inequality.
  • A triple whammy that is best avoided.
  • However, now, three years later, we can assess the efficacy (or not) of this bold experiment.
  • For the three months April-June 2022, corporate tax revenues, y-o-y, are up 30 per cent.
  • Using fiscal 2019-20 as a base, corporate tax revenue has increased by 66 per cent, GDP by 33 per cent — an average tax buoyancy of 2.0 over three years.
  • The previous largest tax buoyancy was in 2006-7 when the world was buoyant.
  • Tentatively, the tax-GDP ratio in the fiscal year 2022-23 will average over 18 per cent in India, a level close to Japan and the US.

Conclusion

In India, the debate should shift to expenditures, and quality of expenditures (and perhaps to reform of the direct tax code). In this regard, suggestion that freebies be critically examined is most timely and welcome.

 Back2Basics: Tax buoyancy and tax elasticity

  • Tax buoyancy: The buoyancy of a tax system measures the total response of tax revenue both to changes innational income and to discretionary changes in tax policies over time, and it is traditionally interpreted as the percentage change in revenue associated to a one percent change in income.
  • Tax elasticity: It refers to changes in tax revenue in response to changes in tax rate.
  • For example, how tax revenue changes if the government reduces corporate income tax from 30 per cent to 25 per cent indicate tax elasticity.
