In the building materials, cement, and TMT steel dealership business, complex credit and debit notes are a weekly reality. Manufacturers (such as UltraTech, Ambuja, ACC, Dalmia, or Shree Cement) routinely issue large credit notes for monthly quantity targets, quarterly turnover rebates, price protection schemes, and rake unloading damage.
At the same time, dealers issue or receive debit notes for freight rate variances, handling charges, or billing rate disputes. A real scenario frequently asked by dealers is: "Cement company gave a Credit Note of ₹6,55,890 and we have a Debit Note of ₹4,35,000. Exactly how much GST must be reversed?"
Immediate Quick Answer: The exact tax reversal depends on whether these notes are Gross (inclusive of 28% GST), Taxable Base, or Financial (Commercial) Credit Notes. If both carry 28% GST and amounts are inclusive: your net GST reversal is ₹48,319.69. If amounts are base values before tax: your net GST reversal is ₹61,849.20. If the credit note is a Financial Credit Note, your reversal is ₹0.00!
1. Step-by-Step Mathematical Calculations
Cement (HSN code 2523) attracts the highest GST slab of 28% (14% CGST + 14% SGST, or 28% IGST). Here are the three commercial cases:
Case A: Values are Gross (Inclusive of 28% GST)
Most credit/debit note PDFs issued by cement manufacturers state the final payable adjustment inclusive of GST:
| Calculation Step | Formula | Amount (₹) |
|---|---|---|
| Gross Credit Note received from Cement Co. | CN Amount | ₹6,55,890.00 |
| Gross Debit Note adjusted | DN Amount | ₹4,35,000.00 |
| Net Difference to be Adjusted | ₹6,55,890 − ₹4,35,000 | ₹2,20,890.00 |
| Taxable Base Value | ₹2,20,890 / 1.28 | ₹1,72,570.31 |
| Total GST to be Reversed (28%) | ₹2,20,890 − ₹1,72,570.31 | ₹48,319.69 |
| • CGST (14%) Reversal (Intra-state) | ₹48,319.69 / 2 | ₹24,159.84 |
| • SGST (14%) Reversal (Intra-state) | ₹48,319.69 / 2 | ₹24,159.84 |
| • IGST (28%) Reversal (Inter-state) | Total 28% tax | ₹48,319.69 |
Case B: Values are Base Taxable Amounts (Excluding 28% GST)
If the credit note voucher specifically states "Taxable Value = ₹6,55,890" and "DN Taxable Value = ₹4,35,000" with GST added on top:
| Calculation Step | Formula | Amount (₹) |
|---|---|---|
| Net Taxable Reduction | ₹6,55,890 − ₹4,35,000 | ₹2,20,890.00 |
| Total Net GST Reversal @ 28% | ₹2,20,890 × 28% | ₹61,849.20 |
| • CGST (14%) Reversal | ₹2,20,890 × 14% | ₹30,924.60 |
| • SGST (14%) Reversal | ₹2,20,890 × 14% | ₹30,924.60 |
Case C: Financial (Commercial) Credit Note — The Zero Reversal Scenario
Under CBIC Circular No. 92/11/2019-GST, when secondary discounts or post-sale turnover incentives are not pre-agreed at the time of original supply, manufacturers issue a Commercial / Financial Credit Note without GST:
- The document does not mention any CGST, SGST, or IGST reduction.
- The cement manufacturer does NOT reduce its output tax liability on the portal.
- Statutory Rule for Dealer: The dealer is NOT required to reverse any Input Tax Credit in GSTR-3B! You retain 100% of the original ITC claimed on the purchase invoice.
2. Statutory Rule: Section 34(2) of the CGST Act
When the cement company issues a valid GST credit note, Section 34(2) states:
"Any registered person who issues a credit note in relation to a supply of goods or services... shall declare the details of such credit note in the return... and the tax liability shall be adjusted... Provided that no reduction in output tax liability of the supplier shall be permitted, if the incidence of tax and interest on such supply has been passed on to any other person."
When the company declares the ₹6,55,890 credit note in its GSTR-1, it automatically lands in your GSTR-2B Table 3 (Part A) as a negative credit. Under Rule 36(4), your eligible ITC for that tax period is reduced automatically.
3. Where to Show This in Form GSTR-3B
There are two methods used by tax professionals, depending on portal auto-population:
- Netting Off in Table 4(A)(5) (Portal Standard): In the modern GST portal system, credit notes reflected in GSTR-2B automatically reduce your "All other ITC" figure in Table 4(A)(5). If your gross purchases for the month had ₹3,00,000 ITC, the net ₹48,319.69 reduction will automatically make it ₹2,51,680.31.
- Reporting in Table 4(B)(2) — Others (Manual Reversal): If the company's credit note does not automatically net off in 2B or you are performing an annual reconciliation, you declare the tax amount under Table 4(B)(2) as an ITC Reversal.
4. What if the Debit Note was Issued by You (Dealer) Against the Company?
In building materials, dealers often raise debit notes on companies for broken bags or rate differences. If the cement company accepts your debit note, they will either issue a matching credit note or offset it against your monthly billing statement. Ensure you verify whether your debit note was registered as a financial voucher or a GST debit note to avoid double-counting tax adjustments.

Frequently Asked Questions
How much tax reversal is needed on a ₹6,55,890 Credit Note and ₹4,35,000 Debit Note in cement?
If both notes carry 28% GST and the figures are tax-inclusive: Net adjustment is ₹2,20,890 (₹6,55,890 - ₹4,35,000). Taxable base is ₹1,72,570.31, and net GST reversal is ₹48,319.69 (₹24,159.84 CGST + ₹24,159.84 SGST). If the figures are base taxable values, net GST reversal @ 28% is ₹61,849.20. If the credit note is a financial/commercial credit note without GST, zero tax reversal is required.
What is the difference between a GST credit note and a financial credit note from a cement company?
A GST credit note is issued under Section 34 with 28% GST reduction, requiring the dealer to reverse matching ITC in Table 4 of GSTR-3B. A financial/commercial credit note (under CBIC Circular 92/11/2019) only adjusts ledger balances for commercial discounts without touching GST; the dealer does not reverse any ITC.
Where is the ITC reversal reported in Form GSTR-3B?
Under the current GST portal mechanism, credit notes uploaded by suppliers in GSTR-1 are automatically netted off against eligible ITC in Table 4(A)(5) via GSTR-2B. Alternatively, manual reversals are declared under Table 4(B)(2) 'Others'.
What is the GST rate on Portland and slag cement?
Cement (HSN code 2523) is taxed under the highest GST slab of 28% (14% CGST + 14% SGST for intra-state supply, or 28% IGST for inter-state supply).
