GSTR-9 Table 8D lapsed ITC calculation: causes, mismatch analysis, and Section 73 notice defense

When compiling your annual return in Form GSTR-9 under Rule 80 of the Central Goods and Services Tax Rules, Table 8 generates significant confusion for accounts teams. Taxpayers often find an unexpected figure in row 8D, titled Difference [A - (B + C)].

A positive value in Table 8D often prompts anxiety that the business has lost valuable input tax credit or that the GST portal will automatically levy penalties. Conversely, automated audit software frequently treats a positive or negative variance as an unexplained discrepancy, prompting tax officers to initiate scrutiny notices in Form GST DRC-01A or Form GST DRC-01 under Section 73 of the Central Goods and Services Tax Act. Understanding the exact arithmetic of row 8D and the legal framework governing lapsed credit enables you to file accurately and defend against erroneous demands.

Mathematical formula for Table 8D

The calculation of Table 8D is automated on the GST portal. Taxpayers cannot manually override the final output in row 8D. The portal executes the following formula:

Each component of this equation serves a distinct statutory purpose. Table 8A represents inward credit auto-populated directly from Form GSTR-2B across all twelve months of the financial year. It reflects both eligible and ineligible inward supplies uploaded and filed by your registered suppliers.

Table 8B auto-populates from Table 6B of Form GSTR-9. It captures the forward-charge inward supply credit actually claimed in your monthly return filings during the financial year. To understand how inward supply credits flow from books to return tables, see our guide on GSTR-9 Table 6 ITC availed bifurcation from books.

Table 8C is a user-declared field where the taxpayer enters credit pertaining to the financial year under review that was claimed in monthly returns filed between April and 30 November of the subsequent financial year. To examine the complete architecture of row 8A through row 8K, review our comprehensive breakdown in the GSTR-9 Table 8 reconciliation formula guide.

Positive vs negative values in Table 8D

The resulting value in Table 8D indicates the reconciliation position of your business:

Why Table 8A differs from Table 8B

Discrepancies between Table 8A and Table 8B are standard across operating businesses. The auto-populated figure in Table 8A rarely equals Table 8B due to genuine commercial and compliance timing differences:

1. Ineligible credit under Section 17(5): Suppliers file invoices for blocked items such as motor vehicles, executive health memberships, or food and catering. These invoices populate Table 8A. Under CBIC Circular No. 170/02/2022-GST, taxpayers report gross credit in Table 4A(5) and permanently reverse blocked credits in Table 4B(1) of Form GSTR-3B. Because Table 8B captures net eligible credit reported in Table 6B, Table 8A remains higher than Table 8B.
2. Credit claimed in subsequent financial year: Invoices received towards the close of the financial year (such as February or March) are frequently recorded in purchase registers after fiscal closing. When claimed in subsequent monthly returns up to 30 November, they reside in Table 8C rather than Table 8B.
3. Unclaimed or disputed invoices: Inward supplies appearing in GSTR-2B where goods were not received, services were deficient, or commercial disputes arose remain unavailed in monthly returns under Section 16(2)(b). These invoices stay in Table 8A but never enter Table 8B.
4. Place of supply errors: A supplier may inadvertently report your GSTIN with an incorrect state place of supply code. Such credit is restricted on the portal and cannot be availed in Form GSTR-3B.
5. Supplier filing timing: Invoices uploaded by vendors after the cut-off date or left in submitted status do not populate Table 8A, causing Table 8B to exceed 8A. For detailed analysis on resolving data mismatches across portals and ledgers, refer to our walkthrough on GSTR-9 Table 8A vs 2B vs books mismatch.

Does positive Table 8D automatically lapse under law?

A common misconception among accountants is that a positive balance in Table 8D represents a tax delinquency or an immediate accounting forfeiture. Under the GST legal framework, positive Table 8D represents credit available in supplier statements that you chose not to avail or were barred from availing.

Under Section 16(4) of the CGST Act, a registered taxpayer cannot claim input tax credit in respect of any invoice or debit note after 30 November following the end of the financial year, or the date of furnishing the relevant annual return, whichever is earlier. If an eligible invoice reflected in Table 8A was not claimed in monthly returns before the statutory deadline, the entitlement to avail that credit formally lapses.

To account for this difference in the annual return, the taxpayer allocates the positive balance of Table 8D into two specific reporting fields. In Table 8E, declare genuine business credits that the taxpayer omitted or chose not to claim within the prescribed time limit. In Table 8F, record credits reflected in Table 8A that are blocked under Section 17(5) or restricted due to place of supply limitations.

The portal combines these unavailed sums with unclaimed import credit from row 8J to generate Table 8K:

Worked rupee computation example

Consider an auto-component manufacturer with the following audited figures for a financial year:

Step by step verification of the arithmetic:

1. Total credit claimed across periods: Table 8B (₹16,20,000) + Table 8C (₹1,10,000) = ₹17,30,000.
2. Initial difference in Table 8D: Table 8A (₹18,50,000) - ₹17,30,000 = ₹1,20,000.
3. Allocation of unavailed credit: Table 8E (₹35,000) + Table 8F (₹85,000) = ₹1,20,000.
4. Unexplained variance remaining: ₹1,20,000 - ₹1,20,000 = ₹0.

By allocating the positive ₹1,20,000 entirely between omitted claims (₹35,000) and blocked credits (₹85,000), Table 8K reports ₹1,20,000 as lapsed credit, demonstrating transparent disclosure with zero unexplained surplus.

Defending against Section 73 demand notices

In recent scrutiny cycles, field formations have issued automated intimations in Form GST DRC-01A and show cause notices in Form GST DRC-01 under Section 73 or Section 74, asserting that discrepancies in Table 8D constitute an unpaid tax liability.

When drafting your reply in Form GST DRC-06, structure your factual and legal defense across clear evidentiary grounds:

First, unavailed credit cannot constitute a tax liability. If the department issues a notice alleging a tax demand on a positive Table 8D balance, state unequivocally that row 8D represents inward supplies appearing in Form GSTR-2B that the taxpayer did not claim in Form GSTR-3B. Section 73 applies strictly to tax not paid, short paid, erroneously refunded, or input tax credit wrongly availed or utilised. Where credit was never availed, no demand under Section 73 can legally stand.

Second, establish fulfillment of Section 16(2) statutory conditions. Where a notice challenges a negative Table 8D balance where claims in 8B and 8C exceed 8A, establish that your business met all four conditions under Section 16(2) of the CGST Act at the time of claim: possession of valid tax invoices issued by registered suppliers under clause (a), physical receipt of taxable goods or underlying services under clause (b), payment of tax charged to the Government under clause (c), and furnishing of regular returns under clause (d).

Third, demonstrate vendor compliance and subsequent period filings. For discrepancies arising from vendor filing delays, compile an invoice-level reconciliation schedule demonstrating that suppliers reported invoices in subsequent periods or amended their GSTR-1 returns. Highlight that Table 8C captures claims made in the subsequent year up to 30 November as permitted by Section 16(4).

Step-by-step checklist to avoid Table 8D disputes

1. Download and aggregate all twelve monthly GSTR-2B JSON or Excel files from the GST portal to establish your gross inward supply baseline.
2. In the Form GSTR-9 dashboard, download the Table 8A Document Details spreadsheet to inspect the exact invoice records captured by GSTN.
3. Identify vendor invoices pertaining to blocked supplies under Section 17(5) and report them in Table 8F rather than leaving them unexplained.
4. Extract purchase invoices for the financial year claimed in monthly returns between April and 30 November of the subsequent financial year, entering the exact total into Table 8C.
5. Verify that Table 8D equals Table 8E plus Table 8F so that zero unaccounted difference remains on the annual return.
