Section 38 CGST Act — GSTR-2B, ITC Statement & Inward Supplies

1. Why Section 38 matters

Searches such as “Section 38 CGST Act”, “what is GSTR-2B”, “GSTR-2B ITC statement”, “GST inward supplies”, “GSTR-1 vs GSTR-2B”, “how to reconcile purchase register with GSTR-2B” and “does GSTR-2B determine ITC” all lead to the framework in Section 38.

Section 38 is the recipient-side companion to Section 37. Section 37 deals with the supplier's outward-supply reporting; Section 38 deals with how those details and other prescribed information are made available to the recipient, together with an auto-generated statement containing input-tax-credit information.

The current framework is fundamentally different from the original proposed two-way GSTR-2 return architecture. Today, the practical centre of Section 38 is the auto-generated GSTR-2B statement and the data ecosystem around supplier filings, amendments, ISD, imports and other prescribed sources.

2. What Section 38 covers

The current Section 38 was substituted with effect from 1 October 2022. The amended structure moved away from the earlier recipient-prepared GSTR-2 model and created the statutory foundation for the auto-generated ITC statement. citeturn0search24

3. Complete statutory structure

Section 38(1) provides that the details of outward supplies furnished under Section 37(1), along with such other supplies as may be prescribed, and an auto-generated statement containing details of input tax credit, are made available electronically to recipients in the prescribed form and manner, within the prescribed time and subject to prescribed conditions and restrictions.

Section 38(2) divides the auto-generated statement conceptually into two broad groups:

• credit that may be available based on inward-supply information; and
• credit that cannot be availed, wholly or partly, where the supplier or transaction falls within the prescribed risk/restriction categories.

The listed restriction categories include specified newly registered persons, persons defaulting in payment of tax, persons whose outward tax reporting significantly exceeds tax paid, persons whose ITC claims exceed the permitted amount by the prescribed limit, persons defaulting under Section 49(12), and other prescribed classes. citeturn0search24

4. Why Section 38 was rewritten

The original GST return architecture contemplated a recipient-prepared inward-supply return. In practice, the GST system moved towards supplier-uploaded data, system-generated recipient information and GSTR-2B.

The Finance Act, 2022 substituted Section 38 with effect from 1 October 2022. The corresponding policy material from the GST Council explained that the return architecture was being aligned with the GSTR-1, GSTR-2B and GSTR-3B system and that the earlier provision requiring recipients to furnish inward-supply details was to be removed in favour of a static GSTR-2B statement. citeturn0search25turn0search24

5. How supplier data reaches the recipient

The practical data flow can be understood as:

For a finance team, this means the supplier's GSTR-1/GSTR-1A reporting becomes an important upstream control for the recipient's ITC reconciliation.

6. What is GSTR-2B?

GSTR-2B is the static, auto-generated statement of input tax credit information made available to a registered recipient.

It is generated from the data available in the GST system from specified sources and provides a structured view of credit that may be available and credit that is shown as not available/restricted according to the applicable rules and system logic.

GSTR-2B is therefore best understood as a reconciliation and ITC-control statement, not as a substitute for the taxpayer's own purchase register, books, invoice verification or Section 16 eligibility analysis.

7. Rule 60 — form and manner

Rule 60 prescribes the form and manner in which the details required under Section 38 are made available through the GST system.

The modern Rule 60 framework provides for the generation of FORM GSTR-2B and specifies the data windows for monthly and quarterly taxpayers. It also incorporates the treatment of information furnished through GSTR-1/IFF and other prescribed sources.

Historical versions of Rule 60 contained the old GSTR-2/GSTR-2A architecture. The rule was subsequently substituted as the GST system moved to the GSTR-2B model. The operative version applicable to a particular tax period should always be checked where historical reconciliation is involved.

8. Sources feeding the ITC statement

Depending on the nature of the transaction and the applicable rules, the recipient-side statement can contain data originating from several GST forms and systems.

Current GSTR-2B instructions also identify supplier GSTR-1/IFF, GSTR-1A and GSTR-5 data and ISD information among the sources represented in the statement. citeturn0search29

9. ITC that may be available

Section 38(2)(a) refers to inward supplies in respect of which credit of input tax may be available to the recipient.

This is a system-level availability classification. The recipient must still independently test the substantive requirements of Section 16 and the restrictions in Section 17.

A good ITC process therefore uses three layers:

1. Document layer: valid invoice/debit note/bill of entry or other eligible document.
2. GST-data layer: supplier/other source has reported the transaction and it appears appropriately in the GST system.
3. Legal-use layer: recipient has actually received the supply, uses it for business/taxable purposes as required, and no blocking/reversal provision applies.

10. ITC that may be shown as unavailable or restricted

Section 38(2)(b) creates a statutory framework for identifying supplies where ITC cannot be availed wholly or partly because prescribed supplier-side or transaction-side conditions are met.

The Act specifically lists categories such as:

• specified newly registered persons during the prescribed period;
• registered persons who have defaulted in payment of tax for the prescribed period;
• persons whose outward tax reported exceeds tax paid beyond the prescribed limit;
• persons whose ITC availed exceeds the permitted amount beyond the prescribed limit;
• persons defaulting in discharging tax liability under Section 49(12); and
• other prescribed classes.

The detailed thresholds and operational implementation depend on the Rules and system notifications. citeturn0search24

11. Supplier-risk and mismatch indicators

The Section 38 rewrite was designed to allow the GST system to communicate more than simple invoice visibility. It also creates a legal basis for identifying certain supplier-risk or mismatch situations.

For example, the statutory architecture contemplates cases where:

• output tax reported by the supplier materially exceeds output tax paid;
• ITC claimed by a supplier materially exceeds the credit that can be availed under the prescribed framework; or
• the supplier has a continuing tax-payment default.

These indicators should not be treated as a blanket declaration that every invoice of a supplier is invalid. They are part of the prescribed mechanism for identifying credit that cannot be availed wholly or partly under Section 38(2).

12. Invoice Management System and Section 38

The GST Council in December 2024 recommended amendments to Section 38 and Rule 60 to provide a legal framework for generation of GSTR-2B based on actions taken by taxpayers on the Invoice Management System (IMS). citeturn0search27

This development is important because it moves GST reconciliation towards a more active recipient-side document workflow. Instead of treating GSTR-2B as merely a downloaded file, businesses can use invoice-level actions and reconciliation decisions as part of their ITC-control process.

13. GSTR-1A and GSTR-2B

GSTR-1A allows specified same-period amendments to supplier outward-supply data. When a supplier changes its reported data through the prescribed mechanism, that amended information can flow into the recipient-side GST data in accordance with the Rules and portal generation cycle.

For the recipient, this creates an important reconciliation point:

14. When GSTR-2B becomes available

Rule 60 prescribes the generation cycle for GSTR-2B. For monthly taxpayers, the statement is generated after the prescribed supplier-reporting cut-off. For quarterly taxpayers, the Rule provides separate timing for the first two months and the third month of the quarter.

The practical result is that the date on which an invoice is uploaded by a supplier and the date on which it appears in a particular GSTR-2B are not necessarily the same date.

15. Why GSTR-2B is static

GSTR-2B is designed as a static statement for a tax period. Once generated, it provides a defined data snapshot that the recipient can use for reconciliation and ITC accounting.

This is different from continuously changing live data. A later supplier amendment may therefore appear in a later statement rather than retroactively changing the historical statement that was already generated.

For this reason, businesses should archive their GSTR-2B files each month rather than relying only on the portal's current display.

16. GSTR-2B reconciliation

A proper GSTR-2B reconciliation compares at least:

A useful reconciliation classification is:

• Matched: GSTIN + invoice + date/value/tax agree within defined tolerance.
• Value mismatch: invoice exists but taxable value/tax differs.
• Missing from 2B: purchase register invoice is not available in the relevant statement.
• Extra in 2B: supplier-reported invoice is not in the purchase register.
• Credit-note impact: supplier credit note affects available ITC.
• Eligibility exception: invoice appears but Section 16/17 analysis prevents or limits credit.

17. Purchase register vs GSTR-2B

Section 38 is the legal foundation behind the recipient-side GST data that businesses reconcile against their purchase registers.

For a strong monthly process, match at minimum:

18. Does GSTR-2B itself create ITC?

No. GSTR-2B is an auto-generated statement of information and system classification. It does not independently create a legal entitlement to input tax credit.

The recipient must still satisfy the substantive requirements of the CGST Act, especially Section 16, and apply restrictions/reversals under Section 17 and other applicable provisions.

19. Section 38 and Section 16

Section 16 sets out the substantive conditions for ITC. Section 38 supplies the recipient-side GST information and statement needed to operate the modern reporting architecture.

20. Section 38 and Section 17

Section 17 contains restrictions such as blocked credits and apportionment/reversal for exempt/non-business use. GSTR-2B may show that an invoice is available in the GST system, but the recipient must still apply Section 17.

Examples include:

• blocked motor-vehicle credit;
• food/catering and other blocked categories;
• works-contract restrictions;
• personal consumption;
• CSR-related restrictions; and
• common-credit reversals.

21. Credit notes and ITC reversal

When a supplier reports a credit note, the recipient must consider the corresponding reduction in ITC. Current GSTR-2B instructions specifically identify credit-note information and explain that the liability/tax treatment continues according to the applicable provisions.

The 55th GST Council also recommended amendments to Section 34(2) and Rule 67B concerning recipient ITC reversal and adjustment of supplier output tax liability against credit notes. citeturn0search27

22. Section 37 and Section 38

In practical terms, the two provisions form one data chain: supplier reporting → GST system → recipient ITC information.

23. Section 38 and GSTR-3B

GSTR-2B is an important input into the recipient's GSTR-3B ITC working, but it is not itself the GSTR-3B return.

A disciplined monthly process should reconcile:

1. purchase register;
2. GSTR-2B;
3. eligible ITC after Sections 16/17 adjustments;
4. credit-note reversals;
5. Rule 37A reversals where applicable;
6. prior-period credits/reversals; and
7. ITC finally reported in GSTR-3B.

24. Rule 37A connection

Rule 37A creates a specific reversal mechanism where a supplier has furnished the relevant invoice/debit-note details but has not furnished the corresponding GSTR-3B return by the prescribed time.

Current GSTR-2B instructions identify a separate table for such Rule 37A situations and the reversal deadline linked to 30 November following the end of the financial year in which the recipient availed the ITC, where the prescribed conditions are met. citeturn0search29

This makes Section 38/GSTR-2B particularly important for year-end ITC controls.

25. Reverse charge supplies

Reverse-charge transactions require separate analysis because the recipient may itself be responsible for tax payment and related documentation.

GSTR-2B can contain information relevant to reverse-charge supplies reported by suppliers where the prescribed framework provides for such communication. However, the recipient's RCM liability should be determined independently from its own books, contracts, invoices and applicable notifications.

26. ISD and inward-supply information

Input Service Distributor invoices and credit/debit notes are part of the broader recipient-side ITC data ecosystem.

For a group with multiple GST registrations, the finance team should distinguish:

• supplier invoices directly received by a GST registration;
• ISD-distributed input services;
• RCM credits;
• import credits; and
• other prescribed credit categories.

Combining all of them into one “2B total” without source classification can produce incorrect ITC reconciliation.

27. Import of goods

Import-of-goods ITC is supported by bill-of-entry/customs data rather than a domestic supplier's GSTR-1. The GSTR-2B ecosystem can therefore contain import-related information through the prescribed data exchange.

For imports, reconcile:

• bill of entry;
• IGST paid at Customs;
• GSTR-2B/import data;
• purchase register;
• goods receipt; and
• ITC claimed in GSTR-3B.

28. E-commerce and other data

Electronic commerce and other specialised GST transactions can generate data through separate statutory reporting channels. Section 38 allows “such other supplies as may be prescribed” to be included in the electronic communication framework.

Therefore, a robust ITC system should not assume that every valid credit will have an identical domestic B2B invoice pattern.

29. Finance Act 2022 restructuring

The most important legislative development for Section 38 was the substitution of the entire section through the Finance Act, 2022, effective 1 October 2022.

The amendment replaced the earlier inward-supply return concept with the present auto-generated statement architecture. This aligned the CGST Act with the practical GSTR-1 → GSTR-2B → GSTR-3B model.

The GST Council's 43rd-meeting return-reform material specifically described the proposed removal of the two-way inward-supply return and adoption of GSTR-2B as the static recipient statement. citeturn0search25

30. 2024 IMS developments

In December 2024, the GST Council recommended a legal framework connecting Section 38 and Rule 60 with the Invoice Management System (IMS), so that GSTR-2B could take account of taxpayer actions on invoices. citeturn0search27

This represents a shift towards a more controlled invoice-level recipient workflow. Businesses should therefore maintain documented rules for accepting, rejecting, deferring and reconciling supplier invoices within the applicable GST-system functionality.

31. Current operational framework

The modern Section 38 compliance model can be represented as:

The exact portal functionality and data tables can evolve. The statutory provisions and Rules applicable to the relevant tax period should therefore control the final compliance position.

32. Detailed practical examples

Example 1 — invoice appears in 2B

A supplier reports a ₹1,00,000 taxable purchase with ₹18,000 GST. It appears correctly in GSTR-2B. The recipient still verifies receipt, invoice validity, business use and Section 16/17 conditions before claiming ₹18,000.

Example 2 — purchase register invoice missing from 2B

The recipient has a valid purchase invoice and GRN, but the supplier has not reported it. The invoice is placed in the “missing from 2B” follow-up bucket and the supplier is contacted.

Example 3 — value mismatch

Books show taxable value ₹5,00,000, while GSTR-2B shows ₹4,80,000. The difference is investigated rather than automatically claiming the higher ITC.

Example 4 — wrong GSTIN

The supplier reports the invoice against another GSTIN of the same group. The recipient should seek correction; internal accounting alone does not transfer the GST-system credit to the correct registration.

Example 5 — credit note

A supplier issues a ₹20,000 credit note plus GST. The recipient tracks the reduction and adjusts/reverses ITC as required.

Example 6 — Rule 37A

The supplier reports the invoice but fails to furnish the relevant GSTR-3B by the prescribed deadline. The recipient monitors the Rule 37A condition and performs reversal/re-availment where required.

Example 7 — import

IGST paid on import is reconciled to the bill of entry and import data rather than expecting a domestic supplier invoice in GSTR-2B.

Example 8 — RCM

A legal service is received under reverse charge. The recipient determines and pays the RCM liability from its own records even if the transaction does not behave like a normal supplier-reported B2B invoice.

Example 9 — same-period supplier amendment

A supplier corrects an invoice through GSTR-1A. The recipient compares the revised information with its purchase register and checks whether the amendment changes the ITC amount.

Example 10 — duplicate ITC risk

An invoice is first matched in one month and later appears again due to an amendment or duplicate reporting. The reconciliation system must identify the document as already accounted for and prevent double credit.

33. Construction and infrastructure examples

For construction, roads, mining, irrigation, pipeline and other infrastructure companies, Section 38 should be integrated into project-wise ITC reconciliation.

A project-level ITC control can follow: PO → GRN → supplier invoice → purchase register → GSTR-2B → eligibility review → GSTR-3B.

34. Legislative development

35. GST Council background

Return-reform architecture

The GST Council's return-reform work progressively moved away from the original two-way GSTR-2 process towards supplier-uploaded data, static GSTR-2B and summary GSTR-3B. The 43rd Council reform material specifically described this transition. citeturn0search25

53rd Council and ITC data flow

The 53rd Council recommendations and subsequent Rule changes strengthened the GSTR-1/GSTR-1A/GSTR-2B workflow and the relationship between supplier reporting and recipient ITC data.

55th Council and IMS

The 55th GST Council recommended amendments to Section 38 and Rule 60 to provide a legal framework for GSTR-2B generation based on taxpayer actions in IMS. citeturn0search27

40. Section 38 GST FAQs

What is Section 38 of the CGST Act?

Section 38 deals with electronic communication of outward-supply and other prescribed information to recipients and the auto-generated statement containing input-tax-credit information.

What is GSTR-2B under Section 38?

GSTR-2B is the static, auto-generated ITC statement generated from prescribed GST data and made available to the recipient.

Is GSTR-2B a return?

No. GSTR-2B is an auto-generated statement. It is not the recipient-filed GSTR-2 return that formed part of the original GST return architecture.

Does GSTR-2B determine ITC eligibility?

No. GSTR-2B is an important GST-data and reconciliation control, but the recipient must independently satisfy Section 16 and apply Section 17 and other applicable provisions.

What is the difference between GSTR-2A and GSTR-2B?

GSTR-2A is a dynamic inward-supply viewing facility, while GSTR-2B is a static auto-generated statement for a defined period and is designed for ITC reconciliation and return preparation.

What is Rule 60 GST?

Rule 60 prescribes the form and manner for making the Section 38 information available, including the GSTR-2B generation framework.

Does GSTR-2B contain GSTR-1 data?

Yes. Supplier-reported outward-supply data furnished through the prescribed mechanisms forms an important source of GSTR-2B.

Does GSTR-1A affect GSTR-2B?

GSTR-1A amendments can feed into recipient-side GST data according to the applicable Rules and portal generation cycle.

What if an invoice is missing from GSTR-2B?

Reconcile it with the purchase register and supplier. Determine whether the supplier has reported it, whether it will appear in a later statement, and whether the substantive ITC conditions are otherwise satisfied.

What if an invoice appears in GSTR-2B but is not in my books?

Do not claim ITC merely because it appears. Investigate the invoice, verify receipt and accounting, and determine whether the transaction actually belongs to the GST registration.

What is Rule 37A in relation to GSTR-2B?

Rule 37A can require reversal of ITC in specified cases where the supplier has reported the invoice but has not furnished the corresponding GSTR-3B by the prescribed time.

Does RCM have to appear in GSTR-2B?

RCM requires separate legal analysis. The recipient should not ignore its own reverse-charge liability merely because a transaction does not appear like a normal supplier-reported B2B invoice.

Does import ITC appear in GSTR-2B?

Import-related information can be incorporated through the prescribed Customs/GST data exchange. The recipient should reconcile it to the bill of entry and IGST paid.

Can I claim ITC only based on GSTR-2B?

No. GSTR-2B is evidence of GST-system reporting, not the complete statutory test for ITC.

Why is GSTR-2B called static?

It is generated for a defined period as a statement based on data available under the prescribed cut-off. Later supplier actions can therefore appear in a subsequent statement rather than changing the historical snapshot.

What is the best way to reconcile GSTR-2B?

Compare purchase register, GSTR-2B, invoice/GRN evidence, supplier data, credit notes, imports, ISD and RCM separately, then apply Section 16/17 eligibility and reconcile the final amount to GSTR-3B.
