What factors limit India’s tax-to-GDP ratio? Suggest measures to widen the tax base without raising rates.

Solution

Introduction: The tax-to-GDP ratio measures how much of national output the State mobilises as tax. A low ratio limits spending on infrastructure, health and education and pushes the Government towards borrowing.

Body:

  • Structural limits: a large informal sector outside the tax net; agricultural income exempt from central income tax; a narrow personal income tax base relative to the population.
  • Design limits: exemptions and deductions; GST exclusions such as petroleum products and electricity, which break the input-credit chain; frequent rate changes and classification disputes.
  • Compliance limits: evasion, under-reporting and litigation backlogs.
  • Measures to widen the base: data analytics using GST, e-invoicing and financial transaction data; formalisation through digital payments; phasing out exemptions in favour of lower uniform rates; simplified compliance for small taxpayers; faster dispute resolution; property tax reform at the local level.

Conclusion: India can raise revenue more through a wider base and better compliance than through higher rates, in line with the Laffer-curve insight that very high rates can reduce collections.
