Input Tax Credit Reversal Under Rules 42 and 43 of CGST Rules


Introduction: Input Tax Credit

What is Input Tax Credit? Well, while a business entity pays taxes to India’s government on any output products, it can avail the open to claim the tax amount earlier paid on the input used in the manufacturing or selling them. This means at the time of paying tax on output, the business entity gets to reduce the tax it has already paid on the inputs and requires to pay only the balance amount. Let’s understand this with an example, just imagine you’re a toy maker and make a purchase of raw material, let’s say wooden logs from a registered dealer and pay the appropriate tax amount on it, which we can assume is Rs. 300. And now on selling the final products (Toys), you collect Rs. 500 from the buyer. Here, instead of paying the entire tax amount of Rs. 500, you can avail the benefit of the Input Tax Credit and reduce the already made tax on input (Rs. 300) from the tax amount levied on the selling of the final product (Rs 500) and pay only the remaining amount (Rs. 200) to the Indian Government. Now, the question arises, what about the wrongly claimed Input Tax Credit, either intentionally or accidentally? What should the business entity do under such an event? Well, answering these questions to you in lucid and layman’s terms is the motive of this article, with a special emphasis on Rules 42 and 43 of CGST Rules. So, make sure you read it till the end.

Input Tax Credit Reversal (ITC Reversal)

When a registered taxpayer of the country wrongly claims ITC, the Input Tax Credit Reversal comes into the picture, which requires it to reverse/return excess ITC claimed during the filing process of GST Returns. In the Reversal of the Input Tax Credit, also referred to as ITC Reversal, the tax amount earlier claimed on the input gets included in the tax liability on the output, hence zeroing down the effect of earlier claimed tax saving under ITC. The taxation authority may also require the responsible business entity to pay interest on the ITC tax saving amount depending upon when such a reversal is done. 

Now, there are certain rules, especially Rule 42 of CGST/SGST rules, which make the reversal of the Input Tax Credit mandatory for the country’s taxpayers as per the circumstances. Let’s take an overview of them to give you a brief understanding.

Process to Calculate ITC Reversal Under Rule 42 of CGST

Before we take a direct dive into the calculation, we need to understand the parts under which Input Tax Credit can be divided:-

  • Specific Credit
  • Common Credit

Specific Credit 

Specific Credit is nothing but an Input Tax Credit that is associated with the supplies used for a single purpose, which can be taxable, non-taxable, or personal. In simple terms, under Specific credit, ITC either will be attributable to the taxable supplies or to the supplies which are exempted from tax/intended to use for personal consumption.

Common credit

Common Credit is ITC that cannot be associated with the supplies which are used for partly taxable and partly non-taxable or personal consumption. Here, the business entity has to calculate and reverse the proportionate ITC amount to the extent of supplies that are non-taxable/used for personal consumption. The rest of the ITC left can be used for claims.

Calculate Input Tax Credit Under Rule 42 of CGST/SGST Rules

  • The very first task for a business entity is to sort out the specific credits (explained above), which can’t be used for ITC claims from the total Input Tax Credit. Do this by following the below instructions:-
  1. The total Input Tax levied on inputs (both goods and services) during a tax period is donated as ‘T.’
  2. The amount of specific credit associated with the inputs, which are to be used for non-business purposes, is denoted as ‘T1.’
  3. The amount of specific credit associated with the inputs, which are used for exempt supplies, is represented as ‘T2.’
  4. Out of the total Input tax, the part which comes under ‘Blocked Credits’ as per Section 17(5) is denoted as ‘T3’
  5. ‘T4 ’ is used to denote the amount of Input tax associated with inputs, which are intended to be used exclusively for effective supplies, including zero-rated stores but don’t include exempted ones.

Note: A business entity must declare T1, T2, and T3 at a summary level in the GSTR 3B form for every tax head. 

  • Out of the total Input Tax Credit, exclude T1, T2, and T3 and calculate the common credit by following the below instructions:-
  1. The amount of Input Tax Credit (ITC) that is credited to the electronic credit ledger of the registered person is represented as ‘C1.’ To derive C1, you need to subtract the total sum of T1, T2, and T3 from T.
  2. To calculate the Common credits (explained above) which are denoted as C2, reduce T4 from C1.
  • Assess the amount of Input Tax Credit out of Common Credit that needs to be reversed by following the below instructions:-
  • The total value of exempt supplies made during the tax period is represented as ‘E.’
  • Total turnover in the State of the registered person during the tax period is represented as ‘F.’
  • ‘D1’ represents the ITC attributable to exempt supplies out of common credit. To calculate D1, you need to first divide ‘E’ by ‘F’ and multiply the resultant by C2.
  • ‘D2’ represents the ITC attributable to non-business purposes out of common credit. To calculate D2, you need to find out 5 percent of C2.
  • ‘C3’ denotes the left ITC eligible for a claim out of common credit. To calculate C3, you need to deduct the sum of D1 and D2 from C2.

After going through the instructions mentioned in the above steps, the D1 and D2 you get in the last will be Input Tax credits that must be reversed.
