Rule 54(1): The ISD Invoice and the ISD Credit Note

Rule 54 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

The ISD invoice is the shortest document in GST. It has six particulars, no taxable value, no tax rate and no HSN code — because it is not evidencing a supply at all. It is a transfer note for credit.

Rule 54(1) requires an ISD to issue an ISD invoice or credit note, "clearly indicating in such invoice/credit note that it is issued only for distribution of ITC". The six particulars are the ISD's name, address and GSTIN; a consecutive serial number not exceeding 16 characters; the date of issuance; the name, address and GSTIN of the recipient; the amount of ITC distributed; and the signature or digital signature. Banking companies, financial institutions and NBFCs may issue any document in lieu thereof, whether or not serially numbered, containing those details. E-invoicing does not apply to ISD invoices.

The six particulars

Rule 54(1) prescribes:

• (a) Name, address and GSTIN of the ISD.
• (b) A consecutive serial number — unique and not exceeding sixteen characters.
• (c) Date of issuance.
• (d) Name, address and GSTIN of the recipient to whom credit is to be distributed.
• (e) Amount of ITC distributed.
• (f) Signature or digital signature of the ISD or its authorised representative.

And the document must say what it is. Rule 39 requires the ISD to issue the invoice "clearly indicating in such invoice that it is issued only for distribution of input tax credit" — the same requirement applying to the credit note under rule 39(1)(l), "for reduction of credit in case the ITC already distributed gets reduced for any reason".

The relaxation for financial institutions: "Banking, financial and non-Banking companies can issue any document in lieu thereof, by whatever name called, whether or not serially numbered but containing the above details."

What is deliberately absent

The Handbook draws the comparison in one line:

"Rule 46 of the CGST Rules governs the tax invoice whereas rule 54(1) and rule 54(1A) govern the provisions of ISD invoices. There is a simplified format for ISD invoice. ISD invoices are not required to include taxable value, tax rate or HSN code."

And elsewhere: "The invoice received from the suppliers is tax invoice, showing taxable value, tax rate, amount, and GSTIN of ISD. The invoice prepared by ISD will not show the taxable amount. It will only show the amount of ITC distributed (as per rule 54(1)). It is only for distribution of taxes."

The FAQ adds the head-wise requirement: the ISD invoice "shall mention CGST, SGST, and IGST separately", and "The credit of IGST, CGST, SGST & UTGST shall be given separately without mentioning tax rate or taxable amount."

Why the omissions make sense. A tax invoice evidences a supply — hence value, rate and classification. An ISD invoice evidences a movement of credit already computed. There is no supply to value, no rate to apply, and nothing to classify.

Two ISD invoices a month, not one per vendor bill

The Handbook settles a question that would otherwise generate enormous paperwork:

"It is not necessary to prepare a separate invoice for distribution against each supplier's invoice. The ISD can collectively at the end of the month prepare two ISD invoices per distinct person to distribute eligible and ineligible ITC separately."

Why two and not one. Because the portal will not accept the same invoice number twice when eligible and ineligible details are entered in Tables 5 and 8 of GSTR-6. Eligible and ineligible distribution →

So the monthly document set for an entity with N distinct persons is 2N ISD invoices — plus credit notes where a reduction has arisen.

The ISD credit note

Rule 39(1)(l) requires an ISD credit note "for reduction of credit in case the ITC already distributed gets reduced for any reason", in the rule 54(1) format.

When it is used:

• A supplier's credit note reduces the credit the ISD holds — apportioned to each recipient in the same ratio as the original distribution.
• A correction of wrong distribution — the same process applies, "including that it was distributed to wrong recipient."
• A 180-day non-payment reversal. The Handbook's FAQ: "The ISD shall raise a credit note on all distinct persons to whom the credit was originally distributed to reverse the ITC distributed. The ITC will be recovered/reversed from the branch units in the same proportion as it is originally distributed. The interest payable shall be paid by the distinct person if applicable. After the payment is made, the credit available will be redistributed in original ratio among distinct persons by preparing ISD invoice or debit note."

Where the reduction exceeds the month's distribution, the excess is added to the output tax liability of the recipient — rule 39(1)(n)(ii).

The ISD debit note, and the gap in the Rules

The Handbook records an honest gap:

"There is no specified format for debit notes to be raised by ISD in the CGST Rules. As the ISD debit note results in addition of credit, one may adopt the same format of an ISD invoice for raising an ISD debit note with a change only in the name of the document."

Rule 39(1)(m) nonetheless contemplates it — an additional amount of ITC arising from a supplier's debit note to the ISD is distributed in the same manner and in the month the debit note is included in GSTR-6.

E-invoicing does not apply

"As per FAQs issued by the GSTN on e-invoicing, it has been provided that e-invoicing is not applicable to the invoices issued by ISD. Therefore, ISD invoices do not attract e-invoicing compliances even if the e-invoicing threshold is crossed under regular GST registrations."

The last clause is the operative one for large groups. A company whose regular registrations are well past the e-invoicing threshold does not carry that obligation into its ISD registration.

This is consistent with rule 54 generally, which carves special document rules out of the ordinary rule 46 regime — the same structure that exempts banks, GTAs, passenger transporters and multiplexes from e-invoicing.

Records to keep

Section 35 requires every registered person to keep accounts of production, inward and outward supply, stock, ITC availed and output tax payable. The Handbook adapts it:

"In case of ISD there is no production, inward supply, outward supply, stock, or output tax payable… It is necessary for the ISD to maintain records in respect of the invoices received for common input services procured by the distinct persons. Also, ISD is required to maintain records of the invoices issued for the distribution of credit."

And from the FAQs: "ISD needs to maintain records relating to the ITC received for distribution and ITC distributed. It needs to keep a proper record of the invoices relating to the same. Other accounts like outward register, inward register, stock records may not be necessary."

Key takeaways

• Six particulars under rule 54(1), and the document must state it is issued only for distribution of ITC.
• No taxable value, no rate, no HSN — but CGST, SGST and IGST shown separately.
• Banks, financial institutions and NBFCs may use any document containing those details, serially numbered or not.
• Two ISD invoices per distinct person per month — eligible and ineligible — not one per vendor bill.
• The ISD credit note reverses distributed credit in the original ratio; an excess is added to the recipient's output tax liability.
• There is no prescribed ISD debit note format — adopt the ISD invoice format with a changed title.
• E-invoicing does not apply to ISD invoices, even where the entity's regular registrations cross the threshold.
• Records: invoices received and invoices issued — no stock or supply registers.
