GST Challan Generation in Form PMT-06: Procedure, Errors and Best Practices

GSTpayment does not end with a bank debit. Under GST, a taxpayer must first generate a challan, deposit the amount into the Electronic Cash Ledger and then use that balance to discharge tax, interest, late fee, penalty or other dues. Form GST PMT-06 is the challan used for this deposit.

When is PMT-06 Used?

PMT-06 is used whenever a taxpayer has to deposit money into the Electronic Cash Ledger. It is relevant in routine filing as well as special compliance situations.

Common use cases include:

• Payment of tax before filing GSTR-3B
• Payment of reverse charge liability
• Payment of interest under Section 50
• Payment of late fee for delayed return filing
• Payment of penalty or other amount
• Monthly tax deposit by QRMP taxpayers
• Cash payment by composition taxpayers
• Deposit during audit, investigation, recovery, or other proceedings

For taxpayers under the QRMP scheme, PMT-06 has a specific role. Such taxpayers have to deposit tax for the first two months of the quarter through Form GST PMT-06 on or before the 25th day of the next month. The amount deposited is used for offsetting liability in the quarterly GSTR-3B.

PMT-06 and QRMP Scheme

Tax professionals must pay close attention to QRMP cases. Under QRMP, return filing is quarterly but tax payment is monthly for the first two months of the quarter.

The taxpayer has two options:

• Fixed sum method
• Self-assessment method

Under the fixed sum method, the taxpayer deposits a prescribed percentage or amount based on the tax paid in the past period. Under the self-assessment method, the taxpayer computes tax based on outward supplies, inward supplies, and available ITC. The deposit is made through PMT-06.

No late fee applies for delay in monthly tax deposit for the first two months. However, interest applies where tax remains unpaid or is paid beyond the due date, as per the applicable provisions. Late fee applies to delay in filing the quarterly GSTR-3B, not to the monthly PMT-06 deposit.

Step-by-Step Procedure to Generate PMT-06

The taxpayer must log in to the GST portal and access the payment section. The challan has to be created before making payment.

Step 1: Identify the liability

Before challan generation, prepare a payment working. The working must separate the amount under each head:

• Integrated tax
• Central tax
• State tax or Union Territory tax
• Cess
• Interest
• Penalty
• Fee
• Other amount

This working is essential because PMT-06 requires head-wise entry.

Step 2: Check existing cash ledger balance

Before depositing fresh cash, check the Electronic Cash Ledger. A balance under the correct head reduces or removes the need for fresh payment.

For example, if the taxpayer has CGST tax balance in cash ledger, that balance is available for CGST tax payment. If the balance is under interest or penalty, it does not settle tax liability.

Step 3: Select the correct major head

The major head refers to the tax category. The taxpayer must choose the correct head:

• IGST
• CGST
• SGST or UTGST
• Cess

A wrong major head creates payment mismatch. For instance, money deposited under IGST will not settle CGST liability unless it is transferred through the permitted mechanism.

Step 4: Select the correct minor head

The minor head identifies the nature of payment. The taxpayer must classify the amount as tax, interest, penalty, fee, or other amount.

This step is a frequent source of errors. Amount deposited under interest will not settle tax. Amount deposited under tax will not settle late fee. The classification must match the liability.

Step 5: Choose payment mode and complete payment

After entering the amount, the taxpayer selects the payment mode and completes the banking process. Once the bank confirms payment, the amount is credited to the Electronic Cash Ledger.

Step 6: Verify CIN and ledger credit

After payment, the taxpayer must verify that the Challan Identification Number is generated and the amount reflects in the Electronic Cash Ledger. Without ledger credit, the taxpayer cannot offset liability in GSTR-3B or other relevant forms.

CPIN, CIN and BRN: Why They Matter

• A PMT-06 transaction creates several reference numbers. Each has a role in audit trail and grievance handling.
• CPIN is the Common Portal Identification Number generated when the challan is created.
• CIN is the Challan Identification Number generated after payment confirmation.
• BRN is the Bank Reference Number generated by the bank.
• Tax professionals must preserve all three numbers along with payment proof, challan copy, bank debit proof, return offset details, and cash ledger screenshot.

Common PMT-06 Errors

Wrong major head

This error arises when tax is deposited under the wrong tax head. A taxpayer deposits under IGST when CGST and SGST are payable, or deposits under cess when no cess liability exists. Return offset fails because the cash balance does not sit under the required head.

Wrong minor head

This error arises when the taxpayer deposits tax under interest, fee, penalty, or other amount. The amount remains in the cash ledger but does not discharge the intended liability.

Bank debit without CIN

In some cases, the bank account is debited but CIN is not generated. This creates a mismatch between bank records and GST portal records. The taxpayer must preserve the bank debit proof and raise the issue through the prescribed GST payment grievance mechanism.

Cash deposit without return filing

Depositing cash through PMT-06 is not the same as filing GSTR-3B. After cash deposit, the taxpayer must offset the liability and file the return. If the return remains unfiled, late fee and interest issues continue.

Reverse charge paid through ITC planning

Reverse charge liability requires cash payment. ITC cannot be used to pay reverse charge tax. Tax professionals must check this before finalising GSTR-3B.

QRMP deposit mismatch

In QRMP cases, the amount deposited through PMT-06 for the first two months must be matched with the final quarterly liability. Any shortfall has to be addressed in the quarterly GSTR-3B along with interest where applicable.

Corrective Measures for Wrong Cash Ledger Deposit

A wrong PMT-06 deposit does not mean the money is lost. Where cash is deposited under the wrong head, the taxpayer has to use the prescribed transfer mechanism to move the balance between heads in the Electronic Cash Ledger.

This correction must be done before return offset. The professional handling the return must not proceed with filing until the cash ledger reflects the right balance under the right head.

Conclusion

Form GST PMT-06 is a key payment document under GST. It connects tax computation, cash deposit, ledger credit, and return filing. For tax professionals, the focus must be on accuracy of head-wise payment, correct classification, payment confirmation and return offset.
