What Is Due Date for GST Return Filing? A Guide for Indian Businesses

Missing a GST deadline can mean late fees, interest where applicable, and unnecessary stress for your business. The tricky part? Not every GST-registered business follows the same filing schedule. The GST return filing due date depends on the return you need to submit, whether you file monthly or quarterly, and any government notification extending the deadline.

In this guide, we'll explain the due dates for GSTR-1 and GSTR-3B, how monthly and quarterly filing differ, and how to keep your business on track.

What Is the GST Return Filing Due Date?

For many regular taxpayers, the usual deadlines are:

• GSTR-1: The 11th of the following month for monthly filers.
• GSTR-1: The 13th of the month following the quarter for quarterly filers.
• GSTR-3B: The 20th of the following month for monthly filers.
• GSTR-3B: Generally the 22nd or 24th of the month following the quarter for eligible quarterly filers, depending on the state or union territory.

These are the standard timelines, not universal deadlines for every taxpayer. Special categories, applicable rules and government extensions can change the date. Always verify the relevant tax period on the official GST Portal.

What Is the Due Date for GSTR-1?

GSTR-1 is the statement used by applicable registered taxpayers to report details of outward supplies, including relevant sales invoices, credit notes and debit notes.

Your filing frequency determines the usual deadline:

• Monthly filing: The 11th of the following month.
• Quarterly filing: The 13th of the month following the quarter.

For example, a monthly GSTR-1 for October would generally be due on 11 November. A quarterly GSTR-1 for the October–December quarter would generally be due on 13 January.

These examples illustrate the usual schedule; check for any applicable extension before filing.

You can review the official GSTR-1 filing guidance for eligibility, filing steps, and other requirements.

What Is the Due Date for GSTR-3B?

GSTR-3B is a summary return through which applicable taxpayers report their tax liabilities and eligible Input Tax Credit (ITC), among other prescribed details.

The usual deadlines are:

• Monthly filers: The 20th of the month following the tax period.
• Quarterly filers: Generally the 22nd or 24th of the month following the quarter, depending on the applicable state or union territory.

For example, a monthly GSTR-3B for October would generally be due on 20 November. Quarterly filers should confirm the deadline applicable to their principal place of business. The official GSTR-3B guidance explains the standard schedule.

Remember, filing GSTR-1 does not automatically mean GSTR-3B has been filed. Check the status of each applicable return separately.

What Is the GST Monthly Return Due Date?

Monthly filing generally means submitting the applicable return for each tax month, even when business activity is lower than usual.

For many regular taxpayers, the usual schedule is:

For example, if you're preparing returns for October, you would generally plan to file GSTR-1 by 11 November and GSTR-3B by 20 November. These are separate obligations. Completing one early does not remove the need to complete the other.

Practical tip: Don't wait until the deadline to reconcile invoices. Review sales, purchases, eligible ITC, and tax liability in advance so you have time to resolve discrepancies.

What Is the GST Quarterly Return Due Date?

Eligible taxpayers who opt for the Quarterly Return Monthly Payment (QRMP) scheme can file GSTR-1 and GSTR-3B quarterly while making applicable tax payments monthly.

The usual quarterly deadlines are:

For example, returns for the October–December quarter would generally be due in January of the following year.

Under QRMP, quarterly returns do not mean that every tax payment can wait until quarter-end. Applicable monthly payment obligations still need attention.

Eligibility and payment requirements depend on the scheme rules. Check the official QRMP scheme guidance before choosing or changing your filing frequency.

What Is the GST Return Filing Last Date for Your Business?

To avoid confusion, identify your taxpayer category, return type, and filing frequency before checking a deadline.

Use this quick checklist:

• Identify your return: Determine which GST return or statement applies to your registration.
• Confirm your filing frequency: Check whether you file monthly or under an eligible quarterly scheme.
• Select the tax period: Make sure you are checking the deadline for the correct month or quarter.
• Check official updates: Review the GST Portal for notifications or extensions.
• Complete the filing: Submit the return and confirm its status on the portal.
• Save your records: Keep the filed return, acknowledgement, and relevant payment details.

A simple compliance calendar makes the GST return filing deadline easier to track, especially if your business manages several GST registrations.

What Happens If You Miss the GST Return Due Date?

Missing a deadline does not mean you should ignore the return. The appropriate next step is to check the outstanding filing, calculate any applicable amount due, and complete the required compliance steps as soon as possible. Depending on the return and circumstances, late filing may result in late fees, interest, or other consequences under the applicable rules.

If you discover a missed deadline:

• Log in to the GST Portal and identify the outstanding return.
• Review any tax liability and applicable interest.
• Check the applicable late fee and payment requirements.
• File the pending return using the prescribed process.
• Retain the acknowledgement and payment records.

The exact consequences depend on the return type, tax liability, and applicable provisions. If your case involves a notice, an ITC discrepancy or a complicated liability calculation, seek qualified GST assistance.

How Can You Check the Latest GST Return Filing Due Date?

Rather than relying only on a calendar image or an old article, verify the deadline for your particular tax period.

Follow these steps:

1. Visit the official GST Portal.
2. Log in using your GST credentials.
3. Navigate to Services → Returns → Returns Dashboard.
4. Select the relevant financial year and tax period.
5. Review the applicable return and its filing status.
6. Check official advisories and notifications for any changes to the deadline.

You should also confirm that you are following the correct filing frequency. A date applicable to monthly filers may not apply to a taxpayer using QRMP. For additional guidance, consult the official GST Portal return manuals.
