GST Online Payment: Process, Methods and Due Dates

Introduction

GST Online Payment allows registered taxpayers to deposit GST, interest, late fees, penalties, and other applicable amounts through the official GST portal. Taxpayers can generate a challan, select a payment method, and verify the deposited amount through the Electronic Cash Ledger.

Many users search for “GST Bill Online,” although GST liability is formally paid by generating a challan and using the deposited balance while filing the applicable GST return. Therefore, taxpayers should understand the complete GST Payment Process instead of treating a bank transaction as final payment.

This article explains how to pay GST online, generate Form GST PMT-06, verify the challan, and meet the applicable payment deadlines.

How Is GST Online Payment Calculated?

GST Online Payment is the process of depositing the cash portion of a taxpayer’s GST liability through the GST portal.

The liability is generally calculated after adjusting eligible Input Tax Credit against the output tax payable.

GST payable in cash = Output GST liability – Eligible Input Tax Credit

This is a simplified calculation for regular output tax liability. The final cash payment may also include reverse-charge liability, interest, late fees, penalties, and amounts that cannot be discharged through ITC.

For example, if the output GST liability is ₹50,000 and eligible ITC is ₹30,000, the remaining ₹20,000 must generally be paid through the Electronic Cash Ledger.

The Electronic Cash Ledger may be used to pay tax, interest, penalties, fees, and other prescribed amounts. In comparison, the Electronic Credit Ledger can be used only for eligible output tax liability, subject to the prescribed utilisation rules.

It is important to note that depositing money into the Electronic Cash Ledger does not automatically discharge the return liability. The taxpayer must offset the amount while filing GSTR-3B or another applicable return.

How to Pay GST Online Through the GST Portal

The following GST Payment Process Online can be used to generate a challan and complete the payment.

Step 1: Log In to the GST Portal

Visit the official GST portal and log in using your registered username and password.

Step 2: Open the Payment Section

After logging in, follow this path:

Services > Payments > Create Challan

A challan may also be generated while filing GSTR-3B if an additional cash payment is required.

Step 3: Enter the Payment Amount

Enter the correct amount under the applicable heads:

• IGST
• CGST
• SGST or UTGST
• Compensation Cess
• Interest
• Late fee
• Penalty
• Other applicable amounts

Check the tax head carefully before proceeding. Payment under the wrong head may prevent the taxpayer from offsetting the intended liability.

Step 4: Select the Payment Method

Select an available payment option, such as internet banking, debit or credit card, UPI, NEFT or RTGS, or permitted Over-the-Counter payment.

Available options and transaction limits may depend on the GST portal, authorised bank, payment gateway, or UPI provider.

Step 5: Generate Form GST PMT-06

After entering the details, generate the challan in Form GST PMT-06.

The GST portal will generate a Common Portal Identification Number or CPIN. The CPIN generally remains valid for 15 days from the date of challan generation.

Step 6: Complete the Payment

Complete the transaction using the selected payment mode. Avoid refreshing the page or initiating another payment while the first transaction is being processed.

Step 7: Verify the CIN

After the amount is successfully credited to the government account, the collecting bank generates a Challan Identification Number or CIN. The CIN appears on the challan and confirms successful payment.

Step 8: Check the Electronic Cash Ledger

Go to:

Services > Ledgers > Electronic Cash Ledger

Confirm that the payment is reflected under the correct tax and payment heads.

Step 9: Offset the GST Liability

Use the cash ledger balance while filing GSTR-3B. GSTR-3B is the summary return through which taxpayers declare and discharge their GST liabilities for a tax period.

GST Online Payment Methods

Taxpayers may Pay GST Online through the payment options displayed on the portal.

Over-the-Counter payments may be made through permitted cash, cheque, or demand draft facilities. Taxpayers using NEFT or RTGS should wait until the amount appears in the Electronic Cash Ledger before filing the return.

GST Payment Due Date

The GST Payment Due Date depends on the taxpayer’s return-filing frequency and the applicable payment form.

The official GST portal states that monthly GSTR-3B is generally due on the 20th of the following month. For quarterly filers, it is generally due on the 22nd or 24th, depending on the State or Union Territory. The government may extend a due date through a notification.

Taxpayers should also review the GST Compliance Calendar FY 2026-27 to track applicable monthly and quarterly deadlines.

Interest, Late Fee and ITC Rules

Interest and late fee apply to different defaults.

Interest on Delayed GST Payment

Interest may apply when the taxpayer fails to pay GST within the prescribed period. Under Section 50, interest is calculated from the day following the date on which the tax became due.

For a current-period liability, the GST portal generally computes interest on the portion discharged through the Electronic Cash Ledger.

However, a liability relating to an earlier period may attract interest on the gross amount, subject to the applicable legal provisions.

Late Fee for Delayed Return Filing

Late fee applies when GSTR-3B or another applicable return is filed after its due date. Therefore, delayed payment interest and return-filing late fees should not be treated as the same consequence.

Use of Input Tax Credit

Eligible ITC may be used only against permitted output tax liability. Interest, late fee, penalty, and similar amounts must generally be paid through the Electronic Cash Ledger.

IGST credit must first be fully utilised before CGST or SGST credit is used, subject to the prescribed order. CGST credit cannot be directly used against SGST liability, and SGST credit cannot be directly used against CGST liability.

The law also provides an order for discharging dues: previous tax-period dues are generally cleared before the current tax-period liability.

CPIN, CIN and GST Payment Status

CPIN and CIN represent different stages of GST Challan Payment.

• CPIN: Generated when Form GST PMT-06 is created. It identifies the challan before payment.
• CIN: Generated after successful payment and bank confirmation.

To check the payment status, go to:

Services > Payments > Challan History

A debit appearing in the bank account alone should not be treated as final confirmation. Taxpayers should verify the CIN and ensure that the amount is reflected in the Electronic Cash Ledger.
