Chapter VIII - Apportionment of tax and settlement of funds

Section 17

Section 17: Apportionment of tax and settlement of funds

Section 17 decides who finally gets IGST that stays in the integrated tax account, for example because the buyer is unregistered, a composition taxpayer or not eligible for credit. The Centre gets an amount equal to the central tax on a similar intra-State supply, and the balance goes to the State, or to the Centre for a Union territory, where the supply takes place.

Statutory text

Bare law

(1) Out of the integrated tax paid to the Central Government,—

(a) in respect of inter-State supply of goods or services or both to an unregistered person or to a registered person paying tax under section 10 of the Central Goods and Services Tax Act;

(b) in respect of inter-State supply of goods or services or both where the registered person is not eligible for input tax credit;

(c) in respect of inter-State supply of goods or services or both made in a financial year to a registered person, where he does not avail of the input tax credit within the specified period and thus remains in the integrated tax account after expiry of the due date for furnishing of annual return for such year in which the supply was made;

(d) in respect of import of goods or services or both by an unregistered person or by a registered person paying tax under section 10 of the Central Goods and Services Tax Act;

(e) in respect of import of goods or services or both where the registered person is not eligible for input tax credit;

(f) in respect of import of goods or services or both made in a financial year by a registered person, where he does not avail of the said credit within the specified period and thus remains in the integrated tax account after expiry of the due date for furnishing of annual return for such year in which the supply was received,

the amount of tax calculated at the rate equivalent to the central tax on similar intra-State supply shall be apportioned to the Central Government.

(2) The balance amount of integrated tax remaining in the integrated tax account in respect of the supply for which an apportionment to the Central Government has been done under sub-section (1) shall be apportioned to the,— (a) State where such supply takes place; and (b) Central Government where such supply takes place in a Union territory:

Provided that where the place of such supply made by any taxable person cannot be determined separately, the said balance amount shall be apportioned to,— (a) each of the States; and (b) Central Government in relation to Union territories, in proportion to the total supplies made by such taxable person to each of such States or Union territories, as the case may be, in a financial year:

Provided further that where the taxable person making such supplies is not identifiable, the said balance amount shall be apportioned to all States and the Central Government in proportion to the amount collected as State tax or, as the case may be, Union territory tax, by the respective State or, as the case may be, by the Central Government during the immediately preceding financial year.

(2A). The amount not apportioned under sub-section (1) and sub-section (2) may, for the time being, on the recommendations of the Council, be apportioned at the rate of fifty per cent. to the Central Government and fifty per cent. to the State Governments or the Union territories, as the case may be, on ad hoc basis and shall be adjusted against the amount apportioned under the said sub-sections.

(3) The provisions of sub-sections (1) and (2) relating to apportionment of integrated tax shall, mutatis mutandis, apply to the apportionment of interest, penalty and compounding amount realised in connection with the tax so apportioned.

(4) Where an amount has been apportioned to the Central Government or a State Government under sub-section (1) or sub-section (2) or sub-section (3), the amount collected as integrated tax shall stand reduced by an amount equal to the amount so apportioned and the Central Government shall transfer to the central tax account or Union territory tax account, an amount equal to the respective amounts apportioned to the Central Government and shall transfer to the State tax account of the respective States an amount equal to the amount apportioned to that State, in such manner and within such time as may be prescribed.

(5) Any integrated tax apportioned to a State or, as the case may be, to the Central Government on account of a Union territory, if subsequently found to be refundable to any person and refunded to such person, shall be reduced from the amount to be apportioned under this section, to such State, or Central Government on account of such Union territory, in such manner and within such time as may be prescribed.

Introduction

This is a government-to-government settlement provision. It does not change the tax a supplier charges or the credit a recipient can take, but it explains why place-of-supply and recipient-registration data reported in returns matter for revenue allocation.

Key takeaways

1

Six situations trigger apportionment

Sub-section (1) covers inter-State supplies and imports to unregistered persons or composition taxpayers, where the registered recipient is not eligible for credit, and where credit is not availed within the specified period.

2

Centre's share, then the balance

The Centre receives tax at a rate equal to central tax on a similar intra-State supply. The balance goes to the State where the supply takes place, or to the Centre where it takes place in a Union territory.

3

Ad hoc 50:50 sharing

Sub-section (2A), inserted by the IGST (Amendment) Act, 2018 with effect from 1 February 2019, allows amounts not yet apportioned to be shared 50:50 on an ad hoc basis on the GST Council's recommendations, adjusted later.

When IGST must be apportioned

Sub-section (1) lists inter-State supplies (clauses (a) to (c)) and imports (clauses (d) to (f)) where integrated tax will not be used as credit. These include supplies to unregistered persons or composition taxpayers under CGST section 10, cases where the registered person is not eligible for credit, and cases where credit is not availed within the specified period and remains after the due date for the annual return for that year.

In each case the amount calculated at the rate equivalent to central tax on a similar intra-State supply is apportioned to the Central Government.

Who gets the balance

Under sub-section (2), the balance goes to the State where the supply takes place, or to the Central Government where the supply takes place in a Union territory.

If the place of supply by a taxable person cannot be determined separately, the balance is shared in proportion to that person's total supplies to each State or Union territory in the financial year. If the taxable person cannot be identified, it is shared among all States and the Centre in proportion to State tax or Union territory tax collected in the preceding financial year.

Interim sharing, interest and refunds

Sub-section (2A) allows amounts not apportioned under sub-sections (1) and (2) to be apportioned 50:50 between the Centre and the States or Union territories on an ad hoc basis, on the Council's recommendations, and adjusted later. It was inserted by section 7 of the IGST (Amendment) Act, 2018 (32 of 2018), which came into force on 1 February 2019.

Sub-section (3) applies the same apportionment to interest, penalty and compounding amounts. Sub-section (4) reduces the IGST collection by the amounts apportioned and requires transfers to the central tax, Union territory tax or State tax accounts as prescribed. Sub-section (5) reduces later apportionment where apportioned tax is refunded.

Practical checklist

Do

  • Report place of supply and recipient GSTIN accurately; these details drive settlement between governments.
  • Treat Section 17 as a fund-settlement rule, not as a basis for charging a different tax amount.

Frequently asked questions

Does Section 17 change how much IGST a supplier charges?

No. It governs how integrated tax already collected is apportioned between the Centre and the States or Union territories.

What is the 50:50 rule?

Sub-section (2A) allows unapportioned amounts to be shared 50:50 between the Centre and the States or Union territories on an ad hoc basis, on the GST Council's recommendations, subject to later adjustment.
