What is the GST e-invoicing requirement for distributors?

E-invoicing under GST is mandatory for taxpayers above a specified annual turnover threshold, which has been progressively lowered over time. Under e-invoicing, the supplier generates each invoice through the Invoice Registration Portal (IRP), which assigns a unique Invoice Reference Number (IRN) and a QR code. The distributor receiving such an invoice should verify that the QR code is valid and that the IRN is present — an invoice without an IRN from a supplier who is required to generate e-invoices is not a valid document for ITC purposes. Distributors who are themselves above the threshold must also generate e-invoices for all B2B sales. The threshold and scope of e-invoicing requirements should be verified against the current GST notification, as changes are announced periodically.

GST Compliance for Ayurvedic Medicine Distributors in India

Q: What GST rate applies to Ayurvedic medicines in India?

Most Ayurvedic medicines listed in the Ayurvedic, Siddha, or Unani pharmacopoeia and manufactured under a drug licence attract GST at 12 percent. Certain Ayurvedic products — particularly those classified as food supplements, nutraceuticals, or health foods rather than as licensed medicines — may fall under a different GST category. The applicable rate depends on how each product is classified under the HSN code system, which is determined by the product's licence, formulation classification, and the HSN code assigned by the manufacturer. A distributor should obtain the HSN code and applicable GST rate for each SKU directly from the principal before invoicing and confirm that the code matches the purchase invoice received.

Q: Which GST returns must an Ayurvedic distributor file?

A registered GST taxpayer who is a distributor will typically file GSTR-1 (outward supply details, filed monthly or quarterly depending on turnover), GSTR-3B (monthly summary return with tax payment), and GSTR-9 (annual return). Distributors with annual turnover above the applicable threshold must file GSTR-9 along with GSTR-9C (the reconciliation statement, where applicable). The GST portal auto-populates GSTR-2B, which reflects the input tax credit available from supplier filings and is the basis for ITC claims. Distributors should reconcile their purchase records against GSTR-2B monthly before finalising GSTR-3B to avoid claiming ITC on invoices that the supplier has not yet uploaded.

Q: How does a distributor claim input tax credit on Ayurvedic medicine purchases?

Input tax credit on purchases from the principal is claimable provided four conditions are met: the purchase invoice is valid and contains all required GST particulars (supplier GSTIN, HSN code, GST amount, invoice number, and date); the supplier has uploaded the invoice in their GSTR-1 filing, making it visible in the distributor's GSTR-2B; the goods have been received; and the tax on the purchase has been paid by the supplier. The distributor should not claim ITC on invoices that do not appear in GSTR-2B — even if the invoice is in hand — until the supplier has filed the corresponding GSTR-1 entry. Claiming ITC on invoices not in GSTR-2B creates a mismatch that can result in a demand notice from the GST department.

Q: What records must an Ayurvedic distributor maintain for GST compliance?

A GST-registered distributor must maintain purchase registers (covering all inward supplies with invoice details), sales registers (all outward supplies with invoice number, buyer GSTIN, HSN code, and GST amount), stock registers showing opening stock, purchases received, sales dispatched, and closing balance per SKU, and a separate account of input tax credit claimed and utilised. All records must be retained for at least six years from the end of the financial year to which they relate, as the GST department can raise audit queries or scrutiny notices within that window. Records should be maintained in a format that allows the distributor to produce any specific invoice or stock movement on request without a significant search.

Q: How should a distributor handle GST on credit notes from the principal?

When the principal issues a credit note — for example, to adjust for returned goods, short supply, or a commercial revision — the distributor must reverse the input tax credit proportionate to the credit note amount. The reversal is reported in GSTR-3B in the month in which the credit note is received or the month for which the ITC reversal applies, whichever is earlier. The credit note should be matched against the original purchase invoice in the distributor's purchase register, and the net ITC position should be updated accordingly. A distributor who does not reverse ITC on credit notes will accumulate an incorrect ITC balance that will surface as a mismatch in the annual GSTR-9 reconciliation.

GST compliance for an Ayurvedic medicine distributor involves more than filing returns on time. It requires maintaining accurate purchase and sales registers, reconciling input tax credit against GSTR-2B every month, and ensuring that every invoice — inward and outward — meets the documentary requirements for a valid ITC claim. Distributors who treat GST as a filing task rather than an ongoing discipline tend to accumulate reconciliation gaps that surface as scrutiny notices or audit demands well after the fact. This guide covers the four core compliance areas for Ayurvedic distributors, the five-step discipline for staying current, and the most common filing errors that create downstream problems.

Four Core GST Compliance Areas for Ayurvedic Distributors

Each area has distinct filing, documentation, and reconciliation requirements. A gap in any one of them can create issues across the others:

Compliance area	What it covers	Key document	Review frequency
Outward supply reporting	All sales invoices issued to retailers, chemists, and sub-stockists, including HSN codes, GSTIN of recipients, and GST amounts	GSTR-1 (monthly or quarterly depending on turnover)	Monthly — GSTR-1 must be filed before the 11th of the following month for the standard filing cycle
Input tax credit management	ITC claimable on purchases from the principal; ITC reversal on credit notes, returns, and exempt or non-business use	GSTR-2B (auto-populated by the portal from supplier filings)	Monthly — reconcile purchase register against GSTR-2B before filing GSTR-3B; do not claim ITC on invoices absent from GSTR-2B
Tax payment and summary return	Net GST liability after ITC offset, payable in cash for any balance; outward tax liability and ITC summary	GSTR-3B (filed monthly by the 20th of the following month)	Monthly — errors in GSTR-3B accumulate; reconcile with GSTR-1 output tax and GSTR-2B ITC position before submission
Annual reconciliation	Full-year reconciliation of all outward supplies, inward supplies, ITC claimed, and tax paid across all monthly returns	GSTR-9 (annual return); GSTR-9C (reconciliation statement for applicable taxpayers)	Annual — filed after the financial year closes; gaps between GSTR-1, GSTR-3B, and books of account must be resolved before filing

Five-Step Monthly GST Compliance Discipline

Running GST compliance as a monthly discipline rather than a filing deadline prevents the accumulation of reconciliation gaps that become difficult to resolve at year-end:

Verify HSN codes and GST rates on each principal invoice received

When a purchase invoice arrives from the principal, confirm that the HSN code matches the product classification and that the GST rate applied is correct for that HSN. For most licensed Ayurvedic medicines, the applicable rate is 12 percent. Products classified differently by the manufacturer — such as nutraceuticals or food supplements — may carry a different rate. A mismatch between the rate on the purchase invoice and the rate on the outward sales invoice creates an ITC claim at one rate and an output liability at another, which will appear as a discrepancy in GSTR-9.

Reconcile GSTR-2B against the purchase register before the 17th

Download GSTR-2B for the month as soon as it is available on the GST portal (typically by the 14th of the following month). Match each entry in GSTR-2B against the corresponding invoice in the purchase register. Invoices present in the purchase register but absent from GSTR-2B cannot be claimed as ITC in the current month — mark them for follow-up with the principal and hold the ITC until the entry appears. Invoices in GSTR-2B that do not match any purchase register entry indicate a possible supplier error and should be queried before the ITC is claimed.

File GSTR-1 with complete outward supply details by the 11th

GSTR-1 must include all B2B invoices issued during the month, with the buyer's GSTIN, invoice number, date, taxable value, HSN code, and GST amount. Credit notes issued during the month must also be uploaded in GSTR-1 under the credit note section. B2C sales — invoices issued to unregistered buyers — are reported as a consolidated entry at the state level for invoices below the specified value threshold. Incomplete or delayed GSTR-1 filing directly affects the buyer's GSTR-2B, which disrupts their ITC claim — this is a common source of retailer or sub-stockist complaints.

File GSTR-3B with the verified ITC and pay any net tax liability

GSTR-3B should be filed only after the GSTR-2B reconciliation is complete. Report the ITC figure from the reconciled GSTR-2B position — not the total from the purchase register. Calculate the net GST payable after offsetting ITC: IGST ITC offsets IGST liability first, then CGST and SGST; CGST ITC offsets CGST liability only; SGST ITC offsets SGST liability only. Any balance after ITC offset must be paid in cash through the electronic cash ledger before the return is filed. Late GSTR-3B filing attracts a late fee per day of delay.

Maintain credit note and return records with the original invoice linkage

Every credit note issued to a customer or received from the principal must be linked in the records to the original invoice it adjusts. Credit notes received from the principal require an ITC reversal in the month of receipt. Credit notes issued to customers reduce outward supply liability in GSTR-1. Without this linkage, the annual GSTR-9 reconciliation will show unexplained differences between the monthly returns and the books of account. A simple credit note register — even a spreadsheet — that records the original invoice number, the credit note number, the reason, the amount, and the GST impact is sufficient to keep this position clean.

Four GST Disciplines That Keep the Distribution Business Clean

Treat GSTR-2B as the ITC authority, not the purchase register

The purchase register records what the distributor received and what should be claimable. GSTR-2B records what is actually claimable in the current period based on supplier filings. These two will not always match in the same month — supplier filing delays are common. Claiming ITC from the purchase register rather than GSTR-2B is the single most frequent source of ITC demand notices. The discipline is to claim only what appears in GSTR-2B, and to follow up with the principal on any missing entries.

Issue compliant invoices on every outward sale

A GST invoice issued to a registered buyer must include the buyer's GSTIN, the distributor's GSTIN, a sequential invoice number, the date, the HSN code, the taxable value, the GST rate, and the GST amount split into CGST and SGST (or IGST for inter-state sales). An invoice missing any of these particulars is not a valid document for the buyer's ITC claim — which can create a dispute with the retailer or chemist who needs the ITC. Invalid invoices also create GSTR-1 filing gaps.

File returns before the deadline, not on it

Late filing of GSTR-1 delays the buyer's GSTR-2B population. Late filing of GSTR-3B attracts a late fee and, if the tax liability is unpaid, interest at 18 percent per annum on the outstanding amount. Building the compliance calendar with internal deadlines two to three days before the statutory deadline gives the distributor time to resolve any last-minute reconciliation issues without penalty. A pattern of late filings also increases the likelihood of scrutiny from the GST department.

Resolve GSTR-1 to GSTR-3B mismatches before the annual return

Differences between the output tax reported in GSTR-1 and the tax paid in GSTR-3B across the year must be resolved before GSTR-9 is filed. An excess in GSTR-1 over GSTR-3B means tax was reported as due but not paid — a demand liability. A shortfall in GSTR-1 relative to GSTR-3B means tax was paid on sales not yet reported. Both create annual reconciliation complexity. Checking GSTR-1 against GSTR-3B quarterly — not just at year-end — gives the distributor time to correct through the normal monthly filing cycle.

Watch for ITC reversals on expired or returned goods

When goods are returned to the principal — whether because of expiry, damage, or a commercial arrangement — the input tax credit already claimed on those goods must be reversed. Failure to reverse ITC on returned stock results in an ITC balance that is higher than what the distributor is entitled to, which will surface as a discrepancy in the annual reconciliation. The amount to reverse is the ITC proportionate to the value of goods returned. The reversal is reported in GSTR-3B in the month the return or debit note is processed, and the corresponding entry should be linked to the original purchase invoice in the records.

Three GST Compliance Metrics Worth Tracking

100%

GSTR-2B to purchase register match rate

Every ITC claimed in GSTR-3B should correspond to an entry in GSTR-2B — any shortfall indicates unclaimed or incorrectly claimed ITC

Zero

Late filing months in the year

A single late GSTR-3B month triggers late fees and interest; a pattern of late filings increases scrutiny risk significantly

≤ 1%

GSTR-1 to GSTR-3B variance at year-end

Output tax reported in GSTR-1 and tax paid in GSTR-3B should reconcile within rounding tolerance — gaps above 1% typically require amendment or explanation in GSTR-9

Five GST Filing Mistakes That Create Problems for Distributors

Mistake	Why it happens	Correction
Claiming ITC from the purchase register without reconciling against GSTR-2B	The purchase register is available immediately; GSTR-2B requires waiting for the supplier to file and for the portal to populate	Hold ITC claims until GSTR-2B is available and reconciled. Follow up with the principal on any missing entries rather than claiming ahead of the portal confirmation
Filing GSTR-1 with incorrect or missing buyer GSTIN on B2B invoices	Buyer GSTIN is sometimes not collected at the time of sale, particularly for newer customers or one-off orders	Collect GSTIN at the point of first sale for every registered buyer. A customer master with verified GSTINs prevents the error at source. Incorrect GSTINs in GSTR-1 are a frequent cause of buyer ITC disputes
Not reversing ITC when credit notes are received from the principal	Credit note processing is often handled separately from the GST compliance routine, leading to the ITC reversal being missed	Maintain a credit note register with the GST impact calculated for each note. Include ITC reversal as a standing checklist item before filing GSTR-3B each month
Applying the wrong GST rate on sales invoices for products classified under different HSN codes	Distributors with a large SKU list may apply a uniform rate without checking individual product classifications	Build a product master that includes the HSN code and applicable GST rate for each SKU, sourced from the principal's invoice. Apply the rate from the product master on every sale invoice — do not use a blanket rate across the portfolio
Leaving year-end GSTR-1 to GSTR-3B mismatches to resolve in GSTR-9	Small monthly differences seem manageable until they accumulate into a material gap by the end of the financial year	Reconcile GSTR-1 output with GSTR-3B tax paid at the end of each quarter. Where differences exist, correct them in the next month's filing through an amendment or an additional liability payment. Resolving quarterly prevents the year-end pile-up

Frequently Asked Questions

What GST rate applies to Ayurvedic medicines in India?▼

Most licensed Ayurvedic medicines listed in the Ayurvedic, Siddha, or Unani pharmacopoeia attract GST at 12 percent. Products classified as nutraceuticals, food supplements, or health foods rather than as licensed medicines may fall under a different category. The applicable rate is determined by the HSN code assigned by the manufacturer, which should be verified on each purchase invoice from the principal. A distributor should not apply a blanket rate across the portfolio without confirming the classification for each SKU.

Which GST returns must an Ayurvedic distributor file?▼

A registered distributor typically files GSTR-1 (outward supply details, monthly or quarterly), GSTR-3B (monthly summary return with tax payment), and GSTR-9 (annual return). GSTR-2B — auto-populated by the portal from supplier filings — is the basis for ITC claims and must be reconciled against the purchase register before each GSTR-3B filing. Distributors above the applicable turnover threshold may also be required to file GSTR-9C (reconciliation statement). Filing obligations and thresholds should be confirmed with a GST-registered accountant, as they are subject to periodic revision.

How does a distributor claim input tax credit on Ayurvedic medicine purchases?▼

ITC is claimable when four conditions are met: the purchase invoice is valid and contains all required GST particulars; the supplier has filed the invoice in GSTR-1, making it visible in the distributor's GSTR-2B; the goods have been received; and the supplier has paid the tax on the transaction. The distributor should claim ITC only on invoices that appear in GSTR-2B — claiming ITC on invoices that are in the purchase register but not in GSTR-2B creates a mismatch that can result in a demand notice.

What records must an Ayurvedic distributor maintain for GST compliance?▼

A GST-registered distributor must maintain a purchase register (all inward supplies with invoice particulars), a sales register (all outward supplies with buyer GSTIN, HSN code, and GST amount), a stock register (opening stock, receipts, dispatches, and closing balance per SKU), and an account of ITC claimed, utilised, and reversed. All records must be retained for at least six years from the end of the financial year. Records should be in a format that allows any specific invoice or stock movement to be produced on request.

What is e-invoicing and when does it apply to distributors?▼

E-invoicing requires taxpayers above a specified annual turnover threshold to generate invoices through the Invoice Registration Portal (IRP), which assigns a unique Invoice Reference Number (IRN) and a QR code. A distributor receiving an e-invoice should verify that the IRN and QR code are present — an invoice without an IRN from a supplier required to generate e-invoices is not a valid ITC document. Distributors who are themselves above the threshold must generate e-invoices for all B2B sales. The applicable threshold and scope are subject to change; current requirements should be verified against the latest GST notification.

How should a distributor handle GST on credit notes from the principal?▼

When a credit note is received from the principal — for returned goods, short supply, or a commercial adjustment — the ITC proportionate to the credit note value must be reversed in GSTR-3B for the month of receipt. The credit note should be matched to the original purchase invoice in the purchase register, and the net ITC position updated. Failure to reverse ITC on credit notes results in an inflated ITC balance that will show as a reconciliation gap in GSTR-9. A simple credit note register that records the original invoice, the credit note details, and the ITC impact is sufficient to keep this position clean.
