# Self-Invoicing Under GST: How to Organise Records Where Required

Organise GST self-invoicing records only after confirming the statutory requirement. Section 31(3)(f) applies to specified reverse-charge supplies received from a supplier treated as unregistered for that provision. It is not a rule that every purchase from an unregistered vendor needs a GST self-invoice. Establish the relevant liability, supplier status and supply facts first, then issue the recipient's invoice within the prescribed time and retain the supporting trail.

## Confirm the actual reverse-charge entry

Identify the supply, supplier category, recipient category and applicable notification on the transaction date. Review conditions, exemptions and relevant choices. A vendor master marked “unregistered” is an identity fact, not a complete reverse-charge conclusion.

Write the basis in a short transaction note or approved recurring arrangement. If the same vendor supplies different activities, review each relevant category rather than extending one decision to every bill. This is especially useful for MSMEs using occasional local vendors, where an overly broad default can create unnecessary tax entries and confusing records.

## Verify supplier status for the relevant date

Obtain the vendor's legal identity, address and registration information. Where a GSTIN is supplied, verify it on the official GST Portal and consider effective dates. Preserve the evidence used for the transaction rather than relying solely on today's master record.

The statutory explanation includes suppliers registered solely for tax deduction under section 51 within the relevant unregistered-supplier expression. Review that specific situation where it arises. Do not assume that the presence of any GST-related identifier automatically removes the self-invoice requirement, or that every registered supplier is treated the same for this clause.

## Record receipt of supply accurately

Maintain goods-receipt records or service completion evidence, the vendor's bill, contract and acceptance details. Rule 47A, effective from 1 November 2024 under Notification 20/2024-Central Tax, requires the covered recipient-issued invoice within thirty days from receipt of the supply. Create a deadline from the supported receipt date.

A vendor bill arriving late does not necessarily change when the supply was received. Likewise, the date accounts enters the bill may differ from actual delivery or service receipt. Keep those dates distinct so a delay in internal approval does not silently reset the statutory clock.

## Prepare the prescribed invoice information

Apply the relevant Rule 46 particulars to the recipient-issued document, with the correct supplier and recipient identities and clear reverse-charge treatment. Use a controlled invoice number and issue date, meaningful supply description, appropriate classification, taxable value, rate and tax heads. Keep the document's role distinguishable from ordinary outward sales invoices.

Link the vendor bill and internal approval as additional evidence. A handwritten vendor receipt may support the commercial expense but should not be assumed to contain every statutory self-invoice particular. Conversely, the self-invoice does not prove that the service was performed; keep the underlying receipt or performance evidence.

## Illustrative required self-invoice

Assume a reviewed unregistered-vendor service is covered by reverse charge, the recipient must self-invoice, taxable value is ₹12,000 and the confirmed assumed aggregate rate is 18%. Tax is ₹2,160. For an ordinary intra-State supply in a State under those assumptions, CGST and SGST are ₹1,080 each.

The recipient records the vendor obligation and its own tax liability distinctly. If it pays the supplier ₹12,000, that supplier payment does not itself discharge the ₹2,160 GST. Keep the self-invoice, applicable payment voucher, bank settlement and tax working linked to the same transaction rather than creating duplicate purchase expenses.

## Review valuation and place of supply separately

A self-invoice should not use an arbitrary value because the supplier did not issue a GST invoice. Read the agreement and identify all consideration and required additions. Related-party, non-cash or other special arrangements can require a different valuation review.

Determine place of supply and tax heads from the applicable goods or services provisions. The vendor's local contact address does not necessarily settle every service-location question. If the transaction involves another State or a cross-border element, collect the relevant facts before applying the ordinary local default.

## Keep timing, payment and credit in separate columns

Track receipt date, self-invoice deadline, issue date, supplier payment, reverse-charge liability, tax payment and credit review. The invoice deadline and tax time of supply are related but not interchangeable. Section 13's current reverse-charge service rules include specific recipient-invoice treatment, so review the operative framework for the actual supply.

ITC eligibility depends on statutory conditions, restrictions and timing, not simply generation of a self-invoice. Do not issue an invented or backdated document to produce a desired credit period. Preserve the chronology and obtain a reasoned treatment for any late discovery.


Send the pending list to the person who can resolve the missing fact. Procurement can confirm vendor identity, the receiving team can confirm delivery and the service owner can confirm completion. Keeping those responsibilities explicit makes the thirty-day document control practical instead of leaving accounts to guess a receipt date from a late bill.
## Control the recurring process

Run a periodic list of applicable reverse-charge receipts without completed self-invoices. Assign the missing evidence or approval to a named role. Review changed supplier status, changed supply scope and expired recurring approvals before carrying forward the old treatment.

A sound self-invoicing file establishes why the obligation exists, when supply was received, how value and tax were determined and which linked documents complete the transaction. That keeps the process focused on required cases and prevents a generic “unregistered purchase” label from replacing the legal analysis.
