Reversal Of Input Tax Credit (ITC) for Non-payment of consideration Within 180 Days and Reavailment of input tax credit Under GST

GST ITC Rule – Reversal and Reclaim of Input Tax Credit If Payment Not Made Within 180 Days

Introduction

Under the GST law, the Input Tax Credit (ITC) system is one of the biggest benefits to businesses. It allows taxpayers to offset the tax paid on purchases (inward supplies) against their outward tax liability. But this benefit comes with certain conditions to maintain transparency and accountability in the tax chain.

One such critical condition is:

The buyer must pay the supplier the invoice amount along with GST within 180 days.

If this is not done, the claimed ITC must be reversed, and interest becomes payable. These provisions are embedded in Section 16(2) of the CGST Act and further detailed in Rule 37 of the CGST Rules.

What Do the Law and Rules Say?

Section 16(2) – CGST Act

As per Section 16(2), a registered person is entitled to claim ITC only when:

1.    They possess a valid tax invoice.

2.    They have received the goods or services.

3.    The tax has been paid to the government by the supplier.

4.    The recipient files the return (GSTR-3B).

But the second proviso adds a vital condition:

“If the recipient fails to pay the supplier the value of the supply along with tax within 180 days, he must reverse the ITC along with interest under Section 50.”

However, if payment is made later, the third proviso assures that:

“The recipient shall be entitled to re-avail the ITC once payment is made.”

Rule 37 – CGST Rules

Rule 37 prescribes the mechanism for this reversal and re-availment:

  • If full or partial payment is not made within 180 days, the recipient shall reverse proportionate ITC in GSTR-3B of the period immediately following the 180-day deadline.
  • Interest must also be paid on such reversed amount.
  • Once payment is made, the ITC can be reclaimed in any future tax period, and there is no time limit for this re-availment.
  • Supplies without consideration under Schedule I, or additional charges under Section 15(2)(b) (e.g., freight paid by the buyer) are deemed to be paid and thus exempt from this rule.

Example to Understand in Practical Terms

Let’s say:

  • Invoice Date: 1st January 2025
  • Value: ₹1,00,000 + GST ₹18,000
  • ITC Claimed in January 2025 GSTR-3B: ₹18,000
  • Payment Not Made Until: 1st August 2025

What should be done?

  • 180 Days end on: 30th June 2025
  • In July 2025, you must:
    • Reverse ₹18,000 ITC
    • Pay interest from 1st Jan to 30th June under Section 50
  • In August 2025, if you make payment:
    • Re-avail ₹18,000 ITC in GSTR-3B
    • No need to file a separate form

Conclusion

So, remember:

  • Claim ITC only when all conditions are met
  • Reverse it if payment is delayed
  • Reclaim it once you make the payment
