Understanding GST Returns and Their Frequency

GST returns are documents that taxpayers submit to the government, detailing sales, purchases, input tax credits, and tax liabilities. The frequency of filing depends on the type and turnover of the business.

• Monthly Returns: Most businesses with an annual turnover above ₹5 crore must file monthly returns.

• Quarterly Returns: Small taxpayers with turnover up to ₹5 crore can opt for quarterly filing under the QRMP scheme.

  
  

Each return type has specific forms and deadlines, which businesses must follow strictly.

Monthly GST Return Due Dates

For businesses filing monthly returns, the key forms and their due dates are:

• GSTR-1 (Outward Supplies)

Due date: 11th of the following month

This form reports all sales and outward supplies made during the month.

• GSTR-3B (Summary Return)

Due date: 20th of the following month

This form summarizes the total sales, purchases, input tax credit claimed, and tax payable.

For example, for sales made in January, GSTR-1 must be filed by February 11, and GSTR-3B by February 20.

Late filing attracts a penalty of ₹50 per day (₹25 CGST + ₹25 SGST), capped at 5% of the taxpayer’s turnover in the state.

Quarterly GST Return Due Dates under QRMP Scheme

The Quarterly Return Monthly Payment (QRMP) scheme allows eligible taxpayers to file returns quarterly while paying taxes monthly.

• GSTR-1

Due date: 13th of the month following the quarter

For the quarter April-June, the due date is July 13.

• GSTR-3B

Due date: Last day of the month following the quarter

For the quarter April-June, the due date is July 31.

• Monthly Tax Payment

Taxpayers must pay tax monthly using Form PMT-06 by the 25th of each month.

This scheme reduces the compliance burden for small taxpayers while ensuring timely tax payments.

Practical Tips to Manage GST Filing Deadlines

Staying organized is key to meeting GST deadlines. Here are some practical tips:

• Maintain Accurate Records

Keep sales and purchase invoices updated and reconciled regularly.

• Use GST Software or Portals

Automate data entry and reminders for due dates using reliable GST filing software.

• Set Calendar Alerts

Mark all due dates on your calendar with reminders a few days in advance.

• File Early

Avoid last-minute rush by preparing returns well before deadlines.

• Consult a Tax Professional

Seek expert advice if you face complex transactions or compliance issues.

Consequences of Missing GST Filing Deadlines

Failing to file GST returns on time can lead to:

• Late Fees and Penalties

₹50 per day for late GSTR-3B filing, capped at 5% of turnover.

• Interest on Tax Due

Interest at 18% per annum on outstanding tax from due date till payment.

• Blocked Input Tax Credit

Buyers may lose input tax credit if suppliers do not file returns timely.

• Legal Notices and Audits

Repeated non-compliance can trigger scrutiny from tax authorities.

Timely filing protects your business from these risks and maintains a good compliance record.
