GSTR-3B without editing: the Council's alternate mechanism for liability and ITC from April 2027, open for comments

FORM GSTR-3B takes liability from the taxpayer’s own FORM GSTR-1 and input tax credit (ITC) from FORM GSTR-2B, and both can now be edited before filing. The GST Council, at its 57th meeting on 8 October 2026, recommended an alternate mechanism under which that editing stops: liability is corrected only through FORM GSTR-1, GSTR-1A or IFF, and ITC only through the Invoice Management System (IMS) and a set of statements and forms. The Council recommended that the mechanism, with the matching amendments to the CGST Rules, 2017, apply from the return period of April 2027.

The drafts are open for public consultation. Stakeholders are invited to send comments by Monday, 30 November. What follows is drawn from the 93-page consultation paper, with its draft rules, forms and circular. None of it is law yet.

Why the Council wants to stop direct editing

Editing auto-populated values creates differences between GSTR-1 and the tax paid, and between GSTR-2B and the ITC taken. The consultation paper names these differences as a frequent cause of demand notices from officers and of system-generated intimations.

The portal already offers GSTR-1A, IMS, a credit reversal statement and an RCM statement. Only GSTR-1A is in the CGST Rules, and some taxpayers do not use the rest properly. The proposal gives each a rule and makes it the only route. Where differences are still settled by editing GSTR-3B each month, that practice has to end with the April 2027 return.

Liability to follow GSTR-1

A new sub-rule (1A) of rule 61 provides that the outward supplies reported in the return shall not be at variance with those furnished in GSTR-1, as amended by GSTR-1A, or through IFF, for the same tax period. An omission or error discovered later is rectified only in the statement of outward supplies for the period in which it is noticed, subject to the time limit in section 37(3) of the Central Goods and Services Tax Act, 2017 (CGST Act). Reverse charge is the exception: an error there can still be adjusted in a later GSTR-3B.

To make that workable, GSTR-1A is to be widened. The amended proviso to rule 59(1) lets a supplier amend or add details in GSTR-1A for an earlier tax period as well, subject to section 37(3), and the Note adds that a recipient’s GSTIN is to become correctable through it.

GSTR-1 is also to classify credit notes, debit notes and advances by the nature of supply (regular, section 9(5) or zero-rated), so that they stop landing in the wrong table of GSTR-3B.

Tax paid through DRC-03 after an audit or inspection

Where tax is paid through FORM GST DRC-03 after an audit, inspection, scrutiny or enforcement action, and the supplier then reports the invoice in GSTR-1 so that the buyer gets credit, the same liability is auto-populated again in GSTR-3B. Editing it out creates a mismatch.

The proposed provisos to rule 142(2) and 142(3) add a Part B to DRC-03. Within seven days of the payment in Part A, the taxpayer may declare the invoices or debit notes against which the tax was paid. Those details then flow into the statement of outward supplies, the liability is not added again in GSTR-3B, and the recipient sees the document in GSTR-2B. The window is short: a DRC-03 payment meant to pass credit to a customer will need its invoice details ready when the tax is paid.

ITC to follow GSTR-2B and IMS

New sub-rule (1B) of rule 61 provides that ITC declared as available on supplies other than reverse charge shall not be at variance with GSTR-2B for that period. Managing credit therefore moves to IMS.

IMS enters the rules as a new sub-rule (6A) of rule 60. Each document may be accepted, rejected or kept pending (a bill of entry only accepted or kept pending), and one left without action when GSTR-3B is filed is deemed accepted. Two time limits are new:

• An invoice or debit note can be kept pending only up to the time allowed for taking ITC under section 16(4) or 16(6). After that it drops out of IMS.
• A credit note can be kept pending until the GSTR-3B of the second succeeding month is filed (monthly filers) or of the next quarter (quarterly filers). It is deemed accepted on that filing, or at the end of the month in which that return falls due if it has not been filed by then.

Keeping a credit note pending has a cost. Under the proposed clause (v) of rule 60(6A), a recipient who has availed and utilised ITC on the original invoice pays interest under section 50(3) on the amount attributable to the credit note. Interest runs from the due date of the return for the period in which it appeared on IMS until the return in which it is accepted or deemed accepted. On the other side, new rule 67B provides that where a recipient rejects a credit note, the supplier pays the attributable tax with interest under section 50 in the next return, as if due from the original return date.

Reverse charge credit and reclaimed ITC

Two portal statements become rules.

• Rule 86D, FORM GST PMT-02B, the Electronic Statement of tax paid on reverse charge basis and ITC claimed. ITC on reverse charge supplies in Tables 4(A)(2) and 4(A)(3) may not exceed the reverse charge liability declared in that return plus the balance in the statement.
• Rule 86C, FORM GST PMT-02A, the Electronic Credit Reversal and Reclaim Statement. ITC reclaimed may not exceed the balance in the statement, which is credited with temporary reversals in Table 4(B)(2).

Reclaimed ITC is to be reported in a new Table 4(AA) of GSTR-3B, instead of Table 4(A)(5) together with Table 4(D)(1). The draft circular states that until Table 4(AA) is live, the method in Circular No. 170/02/2022-GST dated 6 July 2022 continues. Discrepancies in either statement are reported in FORM GST PMT-04, which is amended to cover them.

Both statements let taxpayers report a cumulative opening balance when they were introduced. Once the caps apply, the balance declared then becomes a ceiling on credit, so it should be checked against the books before April 2027.

Excess reversals and FORM GST PMT-10

Unlike a temporary reversal, an excess permanent reversal in Table 4(B)(1), under rules 38, 42 or 43 or section 17(5), has no systematic route back today. The proposed FORM GST PMT-10 allows it to be rectified on self-assessment, within the time limit in the proviso to section 39(9). The amount is credited to the electronic credit ledger, or to the reclaim statement where it should have gone to Table 4(B)(2) in the first place. Until PMT-10 is on the portal, the draft circular allows the excess to be set off against the next period’s 4(B)(1) reversal.

What the draft circular says on using IMS

The draft circular builds on para 4 of Circular No. 170/02/2022-GST. Where the conditions in section 16(2) are not yet met, for example where the goods are yet to be received, the document should be kept pending, not accepted and then reversed in Table 4(B)(2).

Rejecting a credit note adds the tax back to the supplier’s liability. The circular asks recipients to take care before rejecting. Where no ITC was taken on the original invoice, IMS already lets the recipient accept the credit note and state how much ITC to reduce, instead of rejecting it.

A mistaken rejection or acceptance, once GSTR-3B is filed, is undone by the supplier: the document is reported again in an amendment table of a later GSTR-1 or IFF, or amended in GSTR-1A, and the recipient acts on it again in IMS. The recipient cannot fix it alone, which makes supplier co-operation part of the recipient’s ITC position.

Other changes and open points

The draft rules also omit rules 88C and 88D from a prospective date, which is not given. ITC distributed by an ISD as ineligible is to flow to Table 4(D)(2), so that recipients need not reverse it again in Table 4(B)(1).

The consultation paper does not say where comments are to be sent. The Council speaks of the return period of April 2027, while the dates of effect in the draft rules and the draft circular are left blank. The final text may change once the comments are considered.
