Quick Summary & Key Takeaways (Featured Snippet)
1. Overview & The CBIC Circular 170/02/2022-GST Paradigm
Prior to July 2022, taxpayers followed diverse accounting practices in filing Form GSTR-3B. Many businesses netted off ineligible credits before reporting in Table 4(A), or reported Section 17(5) blocked credits only in the non-accounting information Table 4(D)(1). This practice created significant data divergence between supplier GSTR-1 filings, buyer GSTR-2B auto-drafted statements, and the Electronic Credit Ledger.
To establish an unassailable electronic audit trail, the Central Board of Indirect Taxes and Customs (CBIC) issued Circular No. 170/02/2022-GST (dated July 6, 2022), prescribing a strict, uniform mechanism:
Core Regulatory Directives Under Circular 170
100% GSTR-2B Reflection
Every rupee appearing in GSTR-2B must be pulled into Table 4(A), including blocked, ineligible, and restricted invoices.
Permanent vs Temporary
Ineligible credits must be classified into Table 4(B)(1) (irrevocable loss) and Table 4(B)(2) (recoverable upon future event).
Table 4(D)(1) Disclosure
Reclaimed credits must be declared in Table 4(D)(1) to prevent the GSTN risk engine from flagging fraudulent inflation of ITC.
2. Structural Blueprint of GSTR-3B Table 4
Form GSTR-3B Table 4 consists of four primary subsections that govern the monthly addition, subtraction, net crediting, and informational reporting of ITC:
| Table Sub-Clause | Reporting Description | Impact on Electronic Credit Ledger |
|---|---|---|
| Table 4(A) | ITC Available (Import of Goods, Import of Services, RCM Inward Supplies, ISD, All Other ITC) | Gross positive credit intake |
| Table 4(B)(1) | As per Rules 38, 42 & 43 of CGST Rules and Section 17(5) (Permanent Reversals) | Permanent debit / write-off (Non-reclaimable) |
| Table 4(B)(2) | Others (Temporary Reversals: Rule 37 180-days, Section 16(2)(b), Section 16(2)(c)) | Temporary debit (Eligible for future reclaim) |
| Table 4(C) | Net ITC Available [Table 4(A) minus Table 4(B)] | Exact sum credited to Electronic Credit Ledger |
| Table 4(D)(1) | ITC reclaimed which was reversed under Table 4(B)(2) in earlier tax period | Informational disclosure (Matches 4(A)(5) reclaim) |
| Table 4(D)(2) | Ineligible ITC under Section 16(4) and restricted due to PoS rules | Informational disclosure (Does not enter 4(A)) |
3. Permanent Reversals: Table 4(B)(1) Scope
Table 4(B)(1) is reserved strictly for statutory reversals that permanently extinguish the credit. Any amount declared in this sub-table can never be reclaimed in subsequent months:
Section 17(5) Blocked Credits
Motor vehicles for transport of persons (seating capacity ≤ 13 persons, unless used for taxable passenger transport or driving school), food & beverages, outdoor catering, health insurance, club memberships, corporate gifts, free samples, goods lost, stolen, destroyed, or written off.
Rule 38: Banking & Financial Entities
Scheduled commercial banks, NBFCs, and financial institutions opting for the special 50% statutory reduction under Section 17(4). The remaining 50% of monthly input credit must be permanently debited in Table 4(B)(1).
Rule 42: Common Input / Input Services
Proportionate reversal of common tax paid on inputs and input services used for making both taxable and exempt supplies, as well as common credit used for non-business / personal consumption.
Rule 43: Common Capital Goods
Monthly pro-rata depreciation reversal (out of 60 statutory months) on capital assets used concurrently for taxable operations and exempt supplies.
4. Temporary Reversals: Table 4(B)(2) Scope & Timelines
Table 4(B)(2) is the designated staging area for input tax credits that are temporarily ineligible due to statutory timing preconditions under Section 16(2), but which the taxpayer expects to reclaim upon fulfillment of conditions:
Rule 37: Second Proviso to Section 16(2) (180-Day Non-Payment)
Where a recipient fails to pay the supplier the value of supply along with tax within 180 days from the invoice date, the proportionate ITC must be reversed in Table 4(B)(2). Interest under Section 50(3) @ 18% p.a. applies for the period credit was utilized until reversal. Once paid to the supplier, the entire original tax credit can be reclaimed in full.
Section 16(2)(b): Goods in Transit Not Yet Received
If an invoice appears in GSTR-2B because the supplier generated an e-invoice on March 30, but physical delivery of materials arrives at the factory gate on April 4, the credit cannot be availed in March. It must be temporarily reversed under Table 4(B)(2) in March and reclaimed in April.
Section 16(2)(c): Supplier Non-Payment / Verification Discrepancy
Invoices under commercial dispute or where the supplier has not filed GSTR-3B can be temporarily reversed in Table 4(B)(2) pending reconciliation or vendor resolution.
5. Mathematical Formula for Rule 42 Common Input Credit Reversal
Rule 42 outlines the precise mathematical procedure for apportioning common inputs and input services used for both taxable and exempt supplies:
Total ITC for Tax Period (T): Gross input tax on inputs and input services.
T1: Tax exclusively attributable to non-business/personal purposes (Ineligible).
T2: Tax exclusively attributable to exempt supplies (Ineligible).
T3: Tax blocked under Section 17(5) (Ineligible).
T4: Tax exclusively attributable to taxable supplies (including zero-rated exports) (Fully Eligible).
Common Credit (C2) = T - (T1 + T2 + T3 + T4)
Monthly Reversal (D1) = (E ÷ F) × C2
Personal Use Reversal (D2) = 5% × C2
Where:
E = Aggregate value of exempt supplies during the month.
F = Total turnover of the registered person in the State during the tax period.
Total Reversal Reported in Table 4(B)(1) = D1 + D2 + T1 + T2 + T3.
6. Rule 43 Capital Goods: Statutory 60-Month Apportionment
Under Rule 43 of the CGST Rules, capital assets (machinery, computers, commercial vehicles, office equipment) are statutorily presumed to have an economic useful life of 60 months (5 years) from the date of the purchase invoice.
Monthly Capital Goods Reversal Formula:
1. Monthly Common Capital Credit: Tm = Tc ÷ 60
2. Monthly Reversal for Exempt Ratio: Te = (E ÷ F) × Tr
Where Tc is the aggregate tax paid on common capital assets, Tr is the sum of Tm for all active capital assets within their 60-month lifecycle, and E/F is the ratio of exempt turnover to total turnover for the tax period. The resulting Te must be added to the monthly Table 4(B)(1) reversal.
7. Step-by-Step Mechanism: Reclaiming Credit in Table 4(D)(1)
When a temporary restriction is cured (e.g. paying the vendor balance on day 195, or receiving delayed raw materials), the taxpayer re-activates the credit following this statutory workflow:
Step 1: Identify Recovered Invoices in Accounting Ledgers
Extract bank payment proof showing bank clearance of vendor dues, or GRN (Goods Receipt Note) verifying warehouse physical entry.
Step 2: Add Reclaim Amount to Table 4(A)(5) 'All Other ITC'
Because GSTR-2B will not auto-populate an old invoice again, you must manually edit and increase Table 4(A)(5) by the reclaimed tax amount so it credits your Electronic Credit Ledger.
Step 3: Disclose the Exact Reclaim Amount in Table 4(D)(1)
Enter the identical reclaimed tax breakdown (IGST, CGST, SGST) in Table 4(D)(1): 'ITC reclaimed which was reversed under Table 4(B)(2) in earlier tax period'.
Step 4: Maintain Historical Table 4(B)(2) vs 4(D)(1) Register
Ensure cumulative Table 4(D)(1) reclaims never exceed cumulative past Table 4(B)(2) reversals, which would immediately trigger automated scrutiny under Rule 88C/88D.
8. Comprehensive Comparison: Table 4(B)(1) vs Table 4(B)(2)
| Parameter | Table 4(B)(1) Permanent Reversal | Table 4(B)(2) Temporary Reversal |
|---|---|---|
| Statutory Basis | Rules 38, 42, 43 & Section 17(5) | Rule 37, Section 16(2)(b), Section 16(2)(c) |
| Reclaimability | 100% Non-Reclaimable (Lapsed forever) | 100% Reclaimable upon condition fulfillment |
| Reclaim Reporting Table | None | Table 4(A)(5) and Table 4(D)(1) |
| Interest Applicable on Reversal? | No (Reversed in same month of entry) | Yes, if credit was utilized before 180-day reversal (u/s 50(3)) |
| Annual GSTR-9 Mapping | Table 7C, 7D, 7E | Table 7H (Other reversals) / Table 6H (Reclaimed) |
9. Real-World Numerical Case Study: Manufacturing Enterprise
M/s Apex Polychem Pvt Ltd files GSTR-3B for October 2026. Gross ITC auto-populated in GSTR-2B is ₹10,00,000 (IGST ₹4,00,000, CGST ₹3,00,000, SGST ₹3,00,000). During internal accounting verification, the tax team identifies:
- ₹50,000 IGST on executive staff car insurance (Section 17(5) blocked credit).
- ₹30,000 (CGST ₹15k + SGST ₹15k) under Rule 42 common input reversal for exempt solar power generation.
- ₹1,20,000 (CGST ₹60k + SGST ₹60k) on vendor invoices overdue beyond 180 days (Rule 37 non-payment).
- ₹40,000 IGST reclaimed against a September invoice where supplier payment was released on October 12.
| GSTR-3B Table | IGST | CGST | SGST |
|---|---|---|---|
| Table 4(A)(5) All Other ITC (Gross + Reclaim) | ₹4,40,000 (400k + 40k reclaim) | ₹3,00,000 | ₹3,00,000 |
| Table 4(B)(1) Permanent Reversal (Blocked + Rule 42) | ₹50,000 | ₹15,000 | ₹15,000 |
| Table 4(B)(2) Temporary Reversal (180-Day Dues) | ₹0 | ₹60,000 | ₹60,000 |
| Table 4(C) Net ITC Credited to Ledger | ₹3,90,000 | ₹2,25,000 | ₹2,25,000 |
| Table 4(D)(1) Informational Reclaim Disclosure | ₹40,000 | ₹0 | ₹0 |
10. Common Reporting Errors & Pitfalls
Netting Off Ineligible Credit in Table 4(A) Directly
Deducting Section 17(5) credits before entering figures into Table 4(A)(5) results in a reconciliation mismatch against GSTR-2B, prompting automated SCNs from jurisdictional officers.
Parking Section 17(5) Blocked Credits in Table 4(B)(2)
Placing permanent blocked credits in Table 4(B)(2) inflates the recoverable credit pool. During audit inspections, GST authorities cross-examine your temporary ledger and disallow subsequent reclaims.
Reclaiming Without Disclosing in Table 4(D)(1)
If an enterprise adds reclaimed credit directly to Table 4(A)(5) without entering the corresponding amount in Table 4(D)(1), the GST portal's automated risk engine flags an excess ITC claim under Form DRC-01C.
Omitting Annual Rule 42/43 Re-computation Before Due Date
Under Rule 42(2), monthly reversals are interim estimates. Taxpayers must compute the final annual reversal for the entire financial year before November 30 following the end of the FY, and pay any shortfall with interest.
11. Audit Scrutiny & Automated DRC-01C Reconciliation
Under Rule 88D of the CGST Rules, the GST portal automatically compares the ITC availed in Form GSTR-3B with the ITC auto-generated in Form GSTR-2B. If the difference exceeds the prescribed risk threshold (typically 20% and ₹25 Lakhs), the system generates an automated intimation in Form GST DRC-01C:
Defending DRC-01C Intimations Legally:
When Table 4(D)(1) reclaims push Table 4(A)(5) higher than the current month's GSTR-2B, the taxpayer must select Reason Code "ITC claimed on account of earlier reversal under Rule 37 / timing difference" in Part B of Form DRC-01C. Citing the previous tax period's Table 4(B)(2) ARN number and ledger entry satisfies the automated query without officer escalation.
12. Annual Reconciliation in Form GSTR-9
In Form GSTR-9 (Annual Return), the monthly Table 4 figures map into Table 7 and Table 6:
Table 7C: Rule 38 (Banking 50%)
Table 7D: Rule 42 (Exempt Supplies Input Reversal)
Table 7E: Rule 43 (Capital Goods 60-Month Reversal)
Table 7F: Blocked credits under Section 17(5)
Table 7H: Other reversals (including Rule 37 180-days non-payment)
Table 6B: Inward supplies (other than imports and RCM)
Table 6H: Amount of ITC reclaimed (matches cumulative Table 4(D)(1) filings across all 12 months)

14. Frequently Asked Questions
What changes did CBIC Circular No. 170/02/2022-GST introduce in GSTR-3B Table 4?↓
Circular 170 mandated that taxpayers must import the entire gross ITC auto-populated from GSTR-2B into Table 4(A), regardless of eligibility. Permanent reversals (Section 17(5) blocked credit, Rule 38 banking 50% reversal, and Rule 42/43 exempt supply ratios) must be reported in Table 4(B)(1), while temporary reversals (Rule 37 180-day non-payment, Section 16(2)(b) goods in transit, Section 16(2)(c)) must be placed in Table 4(B)(2).
What is the difference between Table 4(B)(1) and Table 4(B)(2) reversals?↓
Table 4(B)(1) is exclusively for permanent reversals that can NEVER be reclaimed in the future (such as Section 17(5) blocked credits on motor vehicles, food, corporate gifts, and Rule 42/43 exempt supply reversals). Table 4(B)(2) is for temporary reversals where the taxpayer can reclaim the credit in Table 4(A)(5) and report it in Table 4(D)(1) once the qualifying condition (e.g., payment to supplier within 180 days or receipt of delayed goods) is fulfilled.
How is Rule 42 common input credit reversal calculated?↓
Rule 42 requires common ITC on inputs and input services (C2) to be apportioned between taxable and exempt turnover. The monthly reversal D1 = (E ÷ F) × C2, where E is the aggregate value of exempt supplies during the month and F is the total turnover of the registered person in the State during the tax period. An additional 5% (D2) is reversed if common credit is used for personal purposes.
How does Rule 43 apply to capital goods ITC reversals?↓
Under Rule 43, the useful life of any capital asset is statutorily treated as 60 months (5 years) from the date of purchase invoice. Common capital goods credit is apportioned monthly by dividing the common tax by 60 (Tm = Tc ÷ 60). The monthly reversal amount Te is calculated as: Te = (E ÷ F) × Tr, where Tr is the sum of Tm for all common capital assets and E/F is the exempt turnover ratio.
How do you reclaim temporarily reversed ITC in subsequent GSTR-3B filings?↓
When the supplier is paid after 180 days or goods in transit are finally received, the taxpayer adds the reclaimed ITC to Table 4(A)(5) (All other ITC) to credit it back into the Electronic Credit Ledger, and concurrently reports the exact reclaimed amount in Table 4(D)(1) ('ITC reclaimed which was reversed under Table 4(B)(2) in earlier tax period') for government audit tracking.
What happens if a taxpayer wrongly reports Section 17(5) blocked credit in Table 4(B)(2)?↓
Reporting Section 17(5) credit in Table 4(B)(2) instead of Table 4(B)(1) inflates the temporary reversal pool and distorts the electronic ledger audit trail. Tax authorities cross-verify GSTR-3B Table 4(D)(1) reclaims against historical Table 4(B)(2) balances. If an ineligible blocked credit is erroneously reclaimed, it attracts demand proceedings under Section 73/74 with 18% p.a. interest under Section 50(3).
