Part of our GST practice: GST Compliance GSTR-2A Reconciliation GSTR-3B Filing GST Audit

Overview

Why ITC Review Goes Beyond Matching

GSTR-2B reconciliation and ITC review is a two-part exercise. The reconciliation part matches the credit recorded in the books and claimed in GSTR-3B against the static GSTR-2B statement; the review part tests every credit against the four conditions of Section 16(2) and screens out credit blocked under Section 17(5). GSTR-2B does not automatically identify every blocked credit, so a manual eligibility review remains essential.

A credit can appear in GSTR-2B and still be ineligible — a blocked credit under Section 17(5) often matches perfectly because the supplier reported it correctly, yet the buyer still cannot claim it. Matching alone therefore does not guarantee a defensible claim. Reconciliation and eligibility review must be performed together, because a GSTR-2B match confirms supplier reporting, not eligibility.

N D Savla & Associates combines GSTR-2B reconciliation with a genuine eligibility review — GSTR-2B to GSTR-3B alignment, Section 16(2) four-condition testing, Section 16(4) time-limit verification, Section 17(5) blocked-credit screening, Rule 36(4) compliance, Rule 42 and Rule 43 common-credit apportionment, ITC reversal in Table 4(B) with interest computation, and re-claim management. Our practice connects with the wider GST compliance framework and coordinates with GSTR-2A reconciliation, GSTR-3B filing, and GST audit.

Because interest on wrongly claimed credit runs from the original claim date until reversal and is never recoverable, early identification is far more valuable than late correction. We deliver a periodic ITC health-check that quantifies the true eligible credit, any exposure from past wrong claims, and the corrective actions needed — giving the business both protected credit and audit readiness.

Common ITC Review Profiles

Which Businesses Need a Deeper ITC Review?

ITC review is relevant for every regular taxpayer, but the input mix, supply profile, and credit complexity change the approach in these common situations.

Manufacturer with a Large Capital Goods Pool

Significant plant and machinery credit — capital goods treatment, Section 16 condition testing, and the depreciation-versus-credit check on the GST component.

Business Claiming Employee Welfare Credit

Food, travel, and welfare expenses — Section 17(5) screening with the obligatory-under-law exception analysis and reversal where the credit is blocked.

Company with Taxable and Exempt Supplies

Mixed-supply credit pool — Rule 42 and Rule 43 common-credit apportionment, exempt-portion computation, and the resulting reversal.

Importer Reconciling IGST Credit

Import credit flowing from ICEGATE — reconciliation across ICEGATE, the bill of entry, and GSTR-2B before the IGST credit is claimed.

Business That Claimed Motor-Vehicle Credit

Vehicles below the prescribed seating capacity — Section 17(5) seating-capacity test, business-use exception, and reversal where blocked with interest.

Enterprise Preparing for GST Audit

Audit-readiness on the credit position — a full ITC health-check that quantifies true eligible credit, any exposure, and the corrective actions needed.

Our Services

Our GSTR-2B Reconciliation & ITC Review Services

Our practice follows a structured eight-step workflow — data gathering, GSTR-2B to GSTR-3B alignment, Section 16(2) testing, Section 16(4) time-limit checks, Section 17(5) screening, Rule 42/43 apportionment, reversal management, and an ITC health-check report. The six service blocks below cover the end-to-end engagement.

01

GSTR-2B to GSTR-3B Alignment & Rule 36(4)

GSTR-2B is the static, fixed statement of available credit for each period, and Rule 36(4) caps claimable credit at the amount it reflects — so a buyer can no longer claim credit on the strength of a valid invoice alone. We download the static GSTR-2B, gather the purchase register, retrieve the filed GSTR-3B, and align the GSTR-3B ITC claim with the GSTR-2B auto-populated figures so any excess over the base is identified immediately, because excess invites automatic scrutiny.
Rule 36(4) – GSTR-2B Cap
02

Section 16(2) Four-Condition Testing

Section 16(2) sets four cumulative conditions: a valid tax invoice, debit note, or prescribed document; actual receipt of the goods or services; payment of the tax to the government by the supplier (verified through GSTR-2B); and the buyer having filed the GSTR-3B for the period. All four must hold together — satisfying three is not enough. We test each claimed credit against every condition, giving particular attention to the third, which is the most commonly missed and links the claim to the portal.
CGST Act – Section 16(2)
03

Section 16(4) Time-Limit & Capital Goods Treatment

Credit must be claimed within the Section 16(4) window, beyond which it lapses permanently — so we prioritise credit approaching the cut-off for timely claim. We also confirm the correct treatment of capital goods credit, which is generally allowed in full in the period of purchase subject to the Section 16 conditions and follows a different timing pattern from the Rule 43 apportionment, ensuring the business does not also claim depreciation on the GST component if it claims the credit.
Section 16(4) – Claim Window
04

Section 17(5) Blocked-Credit Screening

Section 17(5) blocks credit on specific categories even where every Section 16 condition is met — motor vehicles below the prescribed seating capacity, food and beverages, outdoor catering, beauty and health services, club memberships, employee travel benefits, works contract and construction of immovable property, and personal-consumption items, each with its own business-use exception. Because the portal cannot know how a purchase will be used, GSTR-2B does not flag every blocked credit, so we apply the manual business-use test the portal cannot perform.
CGST Act – Section 17(5)
05

Rule 42 & Rule 43 Common-Credit Apportionment

Where a business makes both taxable and exempt supplies, Rule 42 and Rule 43 apportion common credit and require reversal of the exempt portion — with Rule 43 dealing specifically with capital goods credit apportionment. Even a small exempt-supply component triggers the apportionment, and the unreversed exempt portion becomes an exposure. We compute the correct apportionment and reversal for every business with mixed supplies, and reconcile import IGST credit from ICEGATE against the bill of entry.
Rule 42 / Rule 43
06

Reversal, Re-Claim & ITC Health-Check Report

Blocked or ineligible credit is reversed in Table 4(B) of GSTR-3B, with interest from the original claim date until reversal — a permanent cost — so we slot each reversal into the correct period and track any reversal eligible for future re-claim once the disqualifying condition is cured. We then produce an ITC health-check report showing the true eligible credit, the exposure from any past wrong claims, and the corrective actions needed. Our internal audit service supports the wider controls review.

Frequently Asked Questions

Common Questions on GSTR-2B & ITC Review

What is GSTR-2B reconciliation and ITC review?
It is a two-part exercise. The reconciliation part matches the ITC recorded in the books and claimed in GSTR-3B against the static GSTR-2B statement. The ITC review part tests every credit against the four conditions of Section 16(2) and screens out credit blocked under Section 17(5). GSTR-2B lists which credit is available, but it does not automatically identify every blocked credit, so a manual eligibility review remains essential. Together they ensure the business claims only credit that is both reflected in GSTR-2B and genuinely eligible. Our GSTR-2A reconciliation page covers the dynamic-statement matching side.
Why is GSTR-2B the basis for claiming ITC?
GSTR-2B is the static, fixed statement of available credit for each tax period. Under Rule 36(4) of the CGST Rules 2017, ITC is restricted to the credit reflected in GSTR-2B. One of the four Section 16(2) conditions also requires that the supplier has paid the tax to the government — verified through the invoice appearing in GSTR-2B. The portal auto-populates the GSTR-3B ITC table from GSTR-2B. Because it is static, GSTR-2B gives a definitive monthly position. Our GSTR-3B filing page covers the claim return.
What are the four conditions of Section 16(2)?
Section 16(2) of the CGST Act 2017 sets four cumulative conditions that must all hold simultaneously. First, the buyer must hold a valid tax invoice, debit note, or prescribed document. Second, the buyer must have actually received the goods or services. Third, the supplier must have paid the tax to the government — verified through GSTR-2B. Fourth, the buyer must have filed the GSTR-3B for the period. Failure on any one blocks the credit. Our GST compliance page covers the broader framework.
What is blocked credit under Section 17(5)?
Section 17(5) of the CGST Act 2017 blocks ITC on specific categories even where all Section 16 conditions are met. Blocked categories include motor vehicles below the prescribed seating capacity, food and beverages, outdoor catering, beauty and health services, club memberships, employee travel benefits, works contract and construction of immovable property, and personal-consumption items — each with business-use exceptions. GSTR-2B does not automatically flag every blocked credit, so manual review is essential. Blocked credit wrongly claimed must be reversed in Table 4(B) of GSTR-3B with interest. Our GST audit page covers compliance review.
What is Rule 36(4) and how does it affect ITC?
Rule 36(4) of the CGST Rules 2017 restricts the ITC a buyer can claim to the credit reflected in GSTR-2B. The framework progressively tightened until ITC became limited strictly to what appears in GSTR-2B. A buyer can no longer claim credit merely on the strength of holding a valid invoice — the invoice must also appear in GSTR-2B. This makes the supplier's compliance directly control the buyer's ITC availability. Our GST reconciliation page covers the reconciliation framework.
How is blocked or ineligible ITC reversed?
Blocked or ineligible ITC must be reversed in Table 4(B) of the GSTR-3B return. Where it was claimed in an earlier period, the reversal is made in a subsequent GSTR-3B. Interest applies from the date the credit was originally availed until reversal, so the interest is a permanent cost. The ideal practice is to identify ineligible credit before claiming it. Some reversed credit can be re-claimed once the disqualifying condition is cured, though the interest is not recoverable. Our GST notice page covers notice response on ITC disputes.
What is an ITC health-check?
An ITC health-check is a periodic review of the complete input tax credit position to confirm that every claimed credit is eligible, supported, and defensible. It re-examines the GSTR-2B to GSTR-3B alignment, re-tests the Section 16(2) conditions, screens the full purchase base for Section 17(5) blocked credit, verifies Rule 36(4) compliance, checks Rule 42 and Rule 43 apportionment, and confirms all required reversals were made with correct interest. The output shows the true eligible ITC, any exposure, and corrective actions. Our internal audit page covers the wider controls review.
