What is Input Credit under GST ? How to Calculate & claim it?

GST has been implemented by subsuming different taxes with one of the objectives of avoiding the cascading effect of taxes. I.e., the effect of the tax on tax. To overcome this effect, GST consists of a concept called an Input Tax Credit.

Input Tax Credit means reducing the tax liability on outputs by the amount of taxes paid on inputs. It is a procedure to avoid charging of tax on the tax already paid on inputs.

Say, a business purchased the raw material for manufacturing its final product for Rs 100. On such purchases he is liable to pay GST at a certain percentage say @18% i.e. Rs 18 in this case. Rs 18 being known as tax paid on inputs or input tax. Moreover, on selling such product after value additions say for Rs 200 , they collect certain taxes presumed @28%. Which is known as payment of output tax amounting to Rs 56 in this case. Applicability of input tax credit mechanism requires them to deposit the differential tax (output tax liability – input taxes already paid) with the government ie. Rs 56-18= Rs 38 is only the net payable amount, not the whole amount they have collected ie. Rs 56.

Who can claim ITC under GST (Goods and Services Tax Law) in India?

Only a person who is registered under GST is entitled to take credit of tax paid on inward supplies, i.e., purchases of goods or services or both used in the course of furtherance of business. Means Unregistered suppliers are not allowed to take input tax credit for the amount of tax paid on inward supplies of goods or services or both.


Conditions to be satisfied for taking ITC

There are some conditions prescribed under the GST Act for availing the input tax credit. Some of the essential conditions are as under:-

Documents required for ITC

The input tax credit is available to a person who is registered including the input service distributor, based on any of the following documents, namely

  • An invoice issued by the supplier in accordance with the provisions of section 31of the CGST Act 2017
  • A debit note issued by the supplier in accordance with the provisions of section 34 of the same act.
  • Invoice issued  by the recipient along with the proof of payment (Received from an unregistered person and as per Reverse charged)
  • Invoice or credit note or any document issued by an input service distributor

Document must contain relevant information

The input tax credit shall be available to the registered person only if:-

  • All the applicable particulars are contained in the documents
  • Descriptions of goods and services
  • The total value of goods and services
  • Amount of tax charged
  • Place of supply in case of supply
  • GSTIN of receiver and supplier

Receipt of goods or services

A registered person cannot avail the ITC until he does not receive the goods. In case of “bill to ship to” model, where the goods are delivered to a third party on the direction of the registered person who purchased the goods from the supplier then it shall be deemed that the person receiving the goods is a registered person.


Tax charged is paid to the government

For availing the input tax credit, the registered person who charged the tax in respect of such supply has been paid to the government. The payment can be made either in cash or through utilizing the input tax credit.


Filing of return

A registered person can only claim the credit or refund of ITC through the return, so he has to file the return as per section 39.

If depreciation is claimed on tax component, ITC will not be admissible

If the registered person has claimed depreciation on the cost of capital goods under the provisions of the Income Tax Act, 1961, then the ITC shall not be allowed on the tax component.
Thus we can say that the government will not provide you the double benefit on the tax components. As per the government, you cannot claim both the depreciation and ITC as per GST law on tax component at a time. Means either you can claim depreciation on tax component or ITC of such tax paid.


Time limit for availing ITC

According to Section 16 of the CGST Act, 2017, A registered person is entitled to take the input tax credit for any debit note or invoice for the supply of goods or services or both before:

  1. The due date for furnishing the return, u/s 39 of CGST Act, for the month of September following the end of the fiscal year, or
  2. Furnishing of relevant annual return,

Apportionment of credit

  • In case of service or goods partly used for business and partly for the nonbusiness purpose, then the amount of credit shall be limited to the part on input tax that is attributable to the business.
  • ITC shall be restricted to goods or services used for taxable supplies is the same are used for effecting taxable supply as well as exempted supply. ITC may be availed on inward supply for making the zero-rated supply.

Utilization of Input Tax Credits

GST Framework in India

There are three types of taxes available under GST, i.e., CGST, SGST, IGST. Moreover, the same is available to take the credit on input. Their credit can only be set off for specific purposes. The following are the restriction on utilizing credits of various input taxes available:

  • IGST credit,
    1. First, the credit is available to set off against IGST credit,
    2. Then for balance (if any) set off with CGST and then SGST/UTGST.
  • CGST credit,
    1. It is to be utilized against IGST and
    2. then balance with CGST,
  • SGST Credit,
    1. It can be utilized to set off for IGST, and
    2. Then the balance for SGST/UTGST .

ITC treatment in case of input goods and services

The input tax credit concerning inputs or input services, which are being

  • partly used for business and
  • partially for other purposes, or
  • being partly used for effecting taxable supplies including zero-rated goods and services and
  • partly for changing exempt supplies shall be attributed to the purpose of business or
  • for influencing taxable supplies in the following manner, namely:-

Step 1: First, we need to calculate common credit

Total input tax related to inputs and input services in a tax periodT
Less: Input tax on inputs and input services that are intended to be used exclusively for a nonbusiness purpose(T1)
Less: Input tax on inputs and input services that are intended to be used exclusively for exempt supplies(T2)
Less: Input tax which is ineligible for a tax credit (Blocked credits)(T3)
ITC Credited to Electronic Credit LedgerC1
Less: Input tax on inputs and input services that are intended to be used exclusively for taxable supplies including zero-rated supplies(T4)
Common ITC available for apportionmentC2

Step 2: Now we will calculate the credit attributable to exempt supplies (Ineligible credit) by the apportionment of the common credit

D1= (E/F) x C2
D1 = the amount of input tax credit attributable to exempted supplies
E = The aggregate value of exempt goods or services during the tax period
F = The total turnover of the state of the registered person during the tax period
C2 = Common credit available


Step 3: After that, we need to calculate the amount of the credit attributable to nonbusiness if common inputs and input services are used partly business and partly for the nonbusiness purpose

D2 = 5% of C2
D2 = the amount of input tax credit attributable to nonbusiness purpose


Step 4: Now we will calculate the total eligible ITC

C3 = C2 – (D1 + D2)
C3 = the eligible input tax credit from the common credit

Note: The amount equal to the aggregate of D1 and D2 shall be included in the registered person ‘s output tax liability.


Some situations in which ITC cannot be claimed:

  • Motor Vehicle and other conveyance purchased except when used for supplying such vehicles,  imparting training on driving  or transportation of passengers/ goods, navigating or flying such vehicles
