Every accountant faces transactions that were rectified after the close of the financial year. A billing value omitted in January is corrected in September. A customer credit note issued in March is uploaded in October. When completing annual compliance, reporting these transactions requires strict adherence to Form GSTR-9 structure to avoid artificial tax demands.
The primary compliance rule for gstr 9 table 10 and 11 reporting subsequent year outward supply adjustments rests on isolating when tax was actually paid. If an adjustment was declared and discharged in GSTR-3B between April and November of the following financial year, it belongs exclusively in Part V, not in Part II Table 4.
Statutory framework under Section 39(9) of the CGST Act
The legal mechanism permitting corrections in subsequent tax periods is codified in Section 39(9) of the CGST Act 2017. Under this provision, registered persons discovering errors or omissions in previously furnished monthly returns are permitted to rectify those particulars in the return for the tax period during which the error is noticed, subject to payment of interest under Section 50.
The statutory deadline for such rectifications is strictly bounded. Under the proviso to Section 39(9), no rectification is permissible after the thirtieth day of November following the end of the financial year, or the actual date of filing the relevant annual return, whichever is earlier. For outward supplies, complementary reporting instructions in Form GSTR-1 allow upward amendments in Table 9A, debit notes in Table 9B, and credit note downward adjustments in Table 9C.
To reflect these delayed corrections without distorting the turnover of either financial year, the Central Board of Indirect Taxes and Customs established Part V in Form GSTR-9, governed by Rule 80(1) of the CGST Rules 2017. Part V acts as an inter-period bridge, matching the outward tax liabilities of the audited year with payments realized in the subsequent period.
Reporting scope across Part V Tables 10 to 14
According to the official GST Portal Form GSTR-9 User Manual, Part V captures particulars of transactions for the financial year declared in returns of the next financial year till the specified period. Each table has a defined technical role:
- Table 10 (Supplies / tax declared through amendments (+) net of debit notes): Captures additions to outward taxable turnover and output tax. This includes upward rate corrections, omitted invoices disclosed in subsequent year GSTR-1 Table 9A, and original debit notes issued in the subsequent year relating to the previous financial year.
- Table 11 (Supplies / tax reduced through amendments (-) net of credit notes): Captures reductions in outward taxable turnover and output tax. This includes downward invoice value corrections in GSTR-1 Table 9A and credit notes issued between April and November in GSTR-1 Table 9B and 9C.
- Table 12 (Reversal of ITC availed during previous financial year): Captures input tax credit reclaimed or reversed in the subsequent financial year relating to previous year supplies, as detailed in our guide on GSTR-9 Table 6 ITC availed bifurcation from books.
- Table 13 (ITC availed for the previous financial year): Captures eligible input tax credit of the financial year availed between April and November of the next year, forming the baseline figure for GSTR-9 Table 8 reconciliation formula compliance.
- Table 14 (Differential tax paid on account of declaration in Table 10 and 11): Computes the net additional tax payable and records tax actually paid across Integrated Tax, Central Tax, State Tax, and Cess.
Common mistake: Reporting subsequent year amendments in Part II Table 4 instead of Table 10. Table 4 is designed to capture transactions declared in returns filed for the financial year (April to March). Placing subsequent year corrections in Table 4 creates a false mismatch against your filed GSTR-3B liability in Table 9, triggering scrutiny notices.
Why Part V values do not auto-populate on the portal
Unlike Table 4, Table 6A, and Table 8A, the fields in Part V remain completely blank on the GST portal. Taxpayers must compute and insert these figures manually. This design is deliberate.
When you file GSTR-1 and GSTR-3B between April and November, the portal database aggregates totals for that current tax period. While GSTR-1 amendments reference the original invoice date, GSTR-3B consolidates all monthly output tax into a single lump-sum figure in Table 3.1. The portal cannot verify from return data alone whether an amendment in October GSTR-1 was actually discharged in October GSTR-3B, or whether it was offset by other current-year credits.
Consequently, the taxpayer and their tax professional must verify three independent sources before filling Table 10 and Table 11:
- The audited sales register for the target financial year.
- The amendment tables (Table 9A, 9B, 9C) of GSTR-1 filed during April through November of the subsequent period.
- The tax liability discharge ledgers in monthly GSTR-3B filings of that subsequent period.
Worked numerical case study: October adjustments
Consider Alpha Industrial Solutions Private Limited filing Form GSTR-9 for Financial Year 2024-25. During the statutory audit conducted in September 2025, the accounts team identifies two items requiring correction in the October 2025 return (filed in November 2025):
- Transaction A: An unbilled inter-State consulting assignment from February 2025. Taxable value is ₹5,00,000, with IGST @ 18% amounting to ₹90,000. This is reported in October 2025 GSTR-1 and tax is discharged in October 2025 GSTR-3B.
- Transaction B: A price reduction credit note issued on 15 October 2025 for an intra-State supply made in March 2025. Taxable value reduction is ₹2,00,000, with CGST @ 9% (₹18,000) and SGST @ 9% (₹18,000). Total tax reduction is ₹36,000.
The table below summarizes the exact disclosure path in Form GSTR-9 for FY 2024-25:
| GSTR-9 Table | Description | Taxable Value | Integrated Tax | Central Tax | State Tax |
|---|---|---|---|---|---|
| Table 10 | Supplies declared through amendments (+) | ₹5,00,000 | ₹90,000 | ₹0 | ₹0 |
| Table 11 | Supplies reduced through amendments (-) | ₹2,00,000 | ₹0 | ₹18,000 | ₹18,000 |
| Net Impact | Net subsequent year outward adjustment | ₹3,00,000 | ₹90,000 | (₹18,000) | (₹18,000) |
| Table 14 (Payable) | Differential tax payable | Nil | ₹90,000 | ₹0 | ₹0 |
| Table 14 (Paid) | Differential tax paid in GSTR-3B | Nil | ₹90,000 | ₹0 | ₹0 |
In Table 14, the taxpayer reports ₹90,000 under IGST in both the Payable and Paid columns. The downward adjustment of ₹36,000 (CGST ₹18,000 and SGST ₹18,000) reduced output tax liability in October 2025 GSTR-3B, so no additional payment is required for those heads in Table 14.
Common pitfalls: Table 4 confusion and Section 61 scrutiny
A frequent compliance blunder occurs when taxpayers combine subsequent year adjustments with current year turnover in Table 4. Table 4 calculates total tax payable for the year. If you include the ₹5,00,000 consulting supply in Table 4, the portal will show ₹90,000 of unpaid liability in Table 9, because Table 9 only draws tax paid from the twelve GSTR-3B returns filed for that specific financial year.
When Table 9 reflects tax payable exceeding tax paid, the GST portal automated risk assessment flags the return. The jurisdictional tax officer receives an alert and initiates scrutiny proceedings under Section 61 of the CGST Act 2017, issuing a discrepancy notice in Form GST ASMT-10.
Scrutiny notice risk: Filing subsequent year corrections in Table 4 forces you to defend a false liability mismatch in Form GST ASMT-11. Keeping subsequent year amendments strictly in Part V (Tables 10, 11, and 14) documents that tax was lawfully remitted in the subsequent period pursuant to Section 39(9).
Another pitfall involves reporting credit notes issued after 30 November. Under Section 34(2) of the CGST Act, credit notes relating to an annual period cannot reduce output tax liability if issued after the 30 November cut-off. Any commercial credit notes issued after November must be treated as financial adjustments without GST impact and should not be entered in Table 11.

Frequently asked questions
Why are GSTR-9 Table 10 and 11 blank on the GST portal?
The GST portal does not auto-populate Part V tables. Table 10 and Table 11 require manual entry because the portal system cannot independently determine whether an amendment filed between April and November belongs to prior financial year adjustments or current year operations.
Can you report outward supplies in Table 10 if tax was not paid in GSTR-3B?
No. Table 10 is reserved exclusively for supplies and tax declared through amendments in returns of the subsequent financial year up to November. If tax was never declared in GSTR-3B, the liability belongs to Table 4 of GSTR-9 or must be discharged through Form GST DRC-03 with applicable interest.
What is the consequence of entering subsequent year adjustments in Table 4 instead of Part V?
Entering subsequent year adjustments in Table 4 inflates current financial year turnover beyond what was declared in GSTR-3B of that year. This creates an unexplainable mismatch in Table 9 tax payable, prompting automated scrutiny notices in Form GST ASMT-10 under Section 61.
Reconcile your inward records before filing GSTR-9
While outward supplies require careful allocation between Part II and Part V, inward credit reconciliation across financial years demands equal precision. Your GSTR-2B and purchase register files are read in your browser and never uploaded to any server. Identify vendor mismatches and timing differences instantly.
