Complete Guide to Rule 42 of CGST & SGST Rules Rule 42 of the CGST and SGST Rules describes how a taxpayer needs to reverse the input tax credit in relation to goods and/or services used for both taxable as well as exempt supplies. This will be important for those taxpayers who are not in a purely taxable environment. A taxpayer usually operates in a mixed supply environment where it provides both taxable as well as exempt supplies. What is Rule 42 of CGST & SGST Rules? Rule 42 defines how to apportion (divide) and reverse ITC on inputs and input services when they are used for both:
Taxable supplies
Exempt supplies
Business and non-business purposes
It ensures that taxpayers only claim the portion of ITC that relates to taxable supplies.
Why Rule 42 Exists The government allows ITC only on taxable supplies. If a business uses goods/services for exempt supplies as well, then claiming full ITC would cause revenue loss to the government.
When Does Rule 42 Apply? Rule 42 applies in the following cases:
You make mixed supplies (taxable + exempt).
You use inputs and input services for both types of supplies.
You need to reverse the proportionate ITC every month and finalize it annually.
Specific Conditions for ITC Reversal under CGST and SGST Input Tax Credit (ITC) must be reversed in certain situations as prescribed under the CGST and SGST Acts and Rules. These provisions apply equally to both GCST and SGST, and reversal is required in the same proportion for both.

Types of Input Tax Credit Under Rule 42 ITC is divided into three categories:
1. Exclusive Credit for Taxable Supplies (T) ITC is used only for taxable outward supplies.
2. Exclusive Credit for Exempt Supplies (E) ITC is used only for exempt supplies.cannot be claimed. It must be reversed.
3. Common Credit (C) ITC is used for both taxable and exempt supplies.
Step-by-Step Calculation of ITC Under Rule 42 Let:
T = ITC used only for taxable suppli
E = ITC used only for exempt supplies
C1 = Total eligible ITC on inputs + input services
C2 = Blocked credits (ineligible under section 17 (5))
C3 = Common credit after removing T & E
D1 = ITC reversal for exempt supplies
D2 = ITC reversal for non - business use
C4 = Net eligible credit
Step 1: Remove blocked credits C1 – C2 = C
Step 2: Remove ITC exclusively used for non-business purposes This part is D2 = 5 percent of total credit.
Step 3: Identify common credit C3 = C – (T + E + D2)
Step 4: Calculate proportionate reversal exempt supplies D1 = (Exempt turnover / Total turnover) × C3
Step 5: Final eligible ITC C4 = T + (C3 – D1 – D2)
Practical Example of ITC Reversal under Rule 42 Example Data Particulars Symbol Amount Total ITC for the tax period C1 ₹1,20,00 Blocked Credit C2 ₹30,000 ITC Exclusively for exempt supplies E ₹20,000 Exempt turnover - ₹10,00,000 Total Turnover - ₹50,00,000 ITC exclusively for taxable supplies T ₹35,500
Step-wise Calculation Steps Particulars Formula Amount Step 1 Common Credit C = C1 - C2 ₹1,20,000 - ₹30,000 = ₹90,000 Step 2 ITC attributable to exempt supplies (D1) (Exempt turnover / total turnover) * C (₹10,00,000 / ₹50,00,000) * ₹90,000 = ₹18,000 Step 3 ITC attribute to non-business use (D2) 5% of C 5% * ₹90,000 = ₹4,500 Step 4 Eligible Common ITC (C3) C - D1 - D2 ₹90,000 - ₹18,000 - ₹4,500 = ₹67,500
Final Eligible ITC Final eligible ITC includes:
ITC exclusively for taxable supplies (T)
Eligible portion of common credit (C3)
If ITC exclusively for taxable supplies (T) = ₹35,500
Final Eligible ITC = T + C3 ITC = ₹35,500 + ₹67,500
ITC = ₹1,03,000
