 Common Errors in ITC

The errors are expected to be mainly centered around vendor compliances impacting ITC, doubtful credits, missed or short credits. Excess or duplicate credits, debit/ credit note adjustments, capital goods credit vis a vis capitalization, reversal for exempt supplies and reverse charge. We examine some of them in more detail hereunder:

1.   Considering ITC balance to payoff liability under reverse charge

  • Auditor needs to understand place of supply especially for export or import of services.
  • The old service tax law and the GST Act differ and there are some transaction which no longer attract If paid then refund can be sought as it is within limitation. Illustration: Rent a cab or manpower services which were liable for RCM under earlier tax regime but not notified services under GST regime.


3.   ITC could be claimed on the taxes paid under RCM on the GTA services:


  • ITC is only restricted for provider of GTA service who pays at 5%. The customer who pays taxes under RCM could avail ITC if


4.   Treating export of goods/services as exempted goods/services and not availing eligible credits related to same


  • Refund of taxes paid on the goods or services could be availed by the person making the exports even when output GST is not paid on exported goods/exported


5.   Non-reversal of ITC in cases where payment is not made to supplier within 180 days from the date of invoice


  • Reversal of ITC with interest is required. (recently the amendment for no interest has been made- but retrospective applicability not made )
  • The care to enable re credit on future payment can be


6.   Inter-State purchases made from unregistered persons


  • Procure goods only from a registered vendor & avail eligible
  • ITC availed on the basis of invoice of registered dealer provided by the unregistered person would not be available. Further availing ITC on the basis of photocopies may be disputed
  • No restriction for availing 100% of ITC on the purchase of capital goods. [50% credit was in earlier central excise regime].


7.   Availing ITC on supplies specifically blocked u/s 17.


  • Not allowed and if availed - has to be


8.   Availing credit when the same is restricted by rate notification


  • Where ITC was availed when the conditional of notification restricts. Credit to be reversed with


9.   Availing   ITC   merely   on   receipt   of   invoice   without   actual   receipt   of goods/services


  • ITC could be availed only on receipt of invoice and goods ( constructive receipts on instruction of purchaser included).


10.   Non-reversal of proportionate ITC in respect of exempted supplies, non- business purpose use


  • Non-business, non-taxable or exempt supplies not eligible for credit. It would amount to non-compliance of Rule 42 and 43 of the CGST Rules, 2017. supplies, where rate notification restricts availment of ITC (eg restaurant) shall be treated as exempt supplies for the purposes of computation of ITC reversal under Rule 42 & 43 of CGST Rules 2017.


11.   Non-availment of ITC on bank charges


  • ITC could be availed as there is no specific restriction U/S 17(5)


12.   Non-reversal of ITC in respect of goods lost, stolen, destroyed, written off or distributed as gifts/free samples


  • Where ITC is availed and then the goods lost, stolen, destroyed, written off or distributed as gifts/free samples, ITC has to be reversed with
  • Written off could mean fully written off and therefore provision may not impact this.
  • Inputs destroyed before putting into the production process would be
  • Inputs sent as samples are covered in this section. Inputs contained in final products would not be


13.   Delay in availing ITC


  • Avail the ITC on monthly basis and utilize for payment of output liability
  • The absence of proper mechanism/checklist to determine the eligibility of ITC of various purchase/procurement
