  • Section 12(5) – Residuary Provision: If time of supply cannot be determined: date of filing return (if return is to be filed); otherwise, the date of payment of tax.
  • Section 12(6) – Interest / Late Fee / Penalty: Time of supply = date of receipt of such additional amount.

Time of Supply of Services (Section 13)

  • Section 13(1): GST liability on services arises at the time of supply determined under this section.

    1. Invoice issued within prescribed time: Time of supply = earlier of the date of issue of invoice or the date of receipt of payment.

Historical Background and Constitutional Provisions of GST

Historical Background

Before the introduction of GST, India had a complex system of indirect taxation with multiple taxes levied by both Central and State Governments. The Central Government imposed taxes such as Central Excise Duty, Service Tax, Additional Excise Duty, etc., while State Governments imposed Value Added Tax (VAT), Entry Tax, Luxury Tax, Entertainment Tax, etc. This led to problems like the cascading effect of taxes (tax on tax), lack of uniformity, and difficulty in compliance. To remove these issues and create a unified tax system, Goods and Services Tax (GST) was introduced in India on 1 July 2017. GST is a destination-based tax on the consumption of goods and services.

Constitutional Provisions of GST

GST was introduced through the 101st Constitutional Amendment Act, 2016, which made significant changes in the Constitution.

  1. Article 246A

    It grants concurrent powers to both Parliament and State Legislatures to make laws regarding GST. However, Parliament has exclusive power to make laws for inter-state supply.

  2. Article 269A

    It provides that GST on inter-state trade or commerce (IGST) shall be levied and collected by the Central Government and apportioned between the Centre and States.

  3. Article 279A

    It provides for the establishment of the GST Council, which recommends GST rates, exemptions, and policies.

  4. Article 366(12A)

    It defines GST as a tax on the supply of goods or services or both, except taxes on alcoholic liquor for human consumption.

  5. Compensation to States

    The Constitution also provides for compensation to States for the loss of revenue due to the implementation of GST for a specified period.
