Understanding GST and Why Filing Returns is Crucial

Before diving into the ‘how-to’, let’s quickly understand the ‘what’ and ‘why’ of GST returns.

What is GST Exactly?

GST, or Goods and Services Tax, is an indirect tax levied on the supply of goods and services across India. Think of it as a single, comprehensive tax that replaced multiple older indirect taxes like VAT, Service Tax, Excise Duty, etc. It simplifies the tax structure.

GST has different components:

• CGST (Central Goods and Services Tax): Collected by the Central Government on intra-state sales (within the same state).
• SGST (State Goods and Services Tax): Collected by the State Government on intra-state sales.
• IGST (Integrated Goods and Services Tax): Collected by the Central Government on inter-state sales (between different states) and imports.
• UTGST (Union Territory Goods and Services Tax): Collected by the Union Territory government on intra-union territory sales.

This structure ensures a uniform tax system, whether you are managing online GST filing in Delhi or handling the GST filing process Mumbai.

Why is Filing GST Returns Mandatory?

If you are registered under GST, filing returns is a legal obligation. It’s not just paperwork; it’s fundamental to the GST framework. Here’s why it’s crucial:

• Legal Compliance: It fulfills your legal duty as a registered taxpayer, preventing potential legal action or notices from the tax department.
• Input Tax Credit (ITC): Filing returns correctly is necessary to claim ITC on your business purchases. ITC allows you to reduce your final tax liability by deducting the tax already paid on inputs.
• Smooth Business Operations: Regular filing ensures your GST compliance rating remains good, which can be important for business reputation and relationships.
• Essential for Certain Activities: Banks often require proof of GST filing for loan approvals, and it’s frequently a prerequisite for participating in government tenders.

Understanding how to file GST returns accurately and on time is therefore essential for any registered entity or individual.

Prerequisites: Getting Ready to File GST Returns Online

Preparation is key to a smooth online filing experience. Before you log in to the GST portal, ensure you have the following ready:

• GSTIN (Goods and Services Tax Identification Number): You must be registered under GST and have your unique 15-digit GSTIN.
• Valid Login Credentials: Your Username and Password for the official GST Portal.
• Digital Signature Certificate (DSC) or Electronic Verification Code (EVC):
  • DSC: Mandatory for authenticating returns for Companies and Limited Liability Partnerships (LLPs).
  • EVC: Used by other taxpayers (like Proprietorships, Partnerships, Individuals). An OTP is sent to the registered mobile number and email address for verification.
• Accurate Records: This is perhaps the most crucial prerequisite. You need organized data of all your sales (outward supplies) and purchases (inward supplies) for the tax period. Keep invoices, credit notes, and debit notes handy.
• Bank Account Details: Ensure your bank account is linked to your GST profile for tax payments or potential refunds.
• Internet Connection & Compatible Browser: Basic technical requirements for accessing the online portal.

Actionable Tip: Gather all your sales registers, purchase registers, invoices, and financial statements for the relevant tax period before you start the online filing process. This saves significant time and reduces errors.

The Step-by-Step GST Filing Procedure India

This section provides the core steps to file GST returns online. We will primarily focus on filing GSTR-1 (details of outward supplies) and GSTR-3B (summary return and tax payment), as these are the most common returns for businesses and relevant individuals. Follow these steps carefully; this is the primary step-by-step GST filing procedure India.

Step 1: Login to the Official GST Portal

• Open your web browser and navigate to the official GST portal: https://www.gst.gov.in/.
• Click the ‘Login’ button located at the top right corner.
• Enter your Username and Password.
• Enter the characters shown in the CAPTCHA image and click ‘Login’.

Step 2: Navigate to the Returns Dashboard

• Once logged in, hover over the ‘Services’ menu.
• Click on ‘Returns’.
• Select ‘Returns Dashboard’ from the dropdown menu.

Step 3: Select Filing Period

• On the ‘File Returns’ page, select the ‘Financial Year’ (e.g., 2023-24).
• Select the ‘Return Filing Period’ (the specific month or quarter for which you are filing).
• Click the ‘Search’ button.

Step 4: Select the Return to File (GSTR-1)

• The dashboard will display various return tiles for the selected period.
• Locate the tile for ‘Details of outward supplies of goods or services (GSTR-1)’.
• Click on ‘Prepare Online’. (Alternatively, if you use the government’s offline utility tool to prepare your return data, you would click ‘Prepare Offline’ to upload the generated JSON file).

Step 5: Enter Outward Supply Details in GSTR-1

• You will be taken to the GSTR-1 filing page. Here, you need to add details of your sales/outward supplies in various sections (tiles) based on the nature of the transaction:
  • B2B: Invoices issued to other registered taxpayers.
  • B2C Large: Invoices for inter-state sales to unregistered persons where the invoice value exceeds ₹2.5 lakh.
  • B2C Others: Consolidated details of smaller value sales to unregistered persons.
  • Credit/Debit Notes: Details of notes issued to registered/unregistered persons.
  • Exports: Details of exported goods or services.
  • Nil Rated Supplies: Details of supplies that attract zero tax.
  • HSN Summary: Summary of outward supplies based on Harmonized System of Nomenclature (HSN) codes.
• Click on each relevant tile and add the required invoice details accurately. Precision here is vital, whether you’re involved in GST return filing Chennai or managing the GST returns filing process Hyderabad.
• After entering all details, scroll down and click ‘Generate GSTR-1 Summary’. This may take a few minutes. Refresh the page periodically.
• Once generated, review the summary carefully to ensure all data is correct.

Step 6: Submit and File GSTR-1

• Once you are satisfied with the summary, tick the declaration checkbox acknowledging the correctness of the information.
• Click the ‘Submit’ button. Important Note: Once submitted, you cannot change the GSTR-1 details for that specific tax period. Any corrections must be made via amendments in subsequent returns.
• After successful submission, the ‘File Return’ button will be enabled. Click it.
• A pop-up will appear. Choose either ‘File with DSC’ or ‘File with EVC’.
  • Select DSC if applicable (Companies/LLPs) and proceed with your digital signature.
  • Select EVC if applicable. Enter the OTP received on your registered email and mobile number.
• Upon successful authentication, your GSTR-1 will be filed. You will receive an Acknowledgement Reference Number (ARN) on screen and via email/SMS.

Step 7: Prepare and File GSTR-3B (Summary Return)

• Go back to the ‘Returns Dashboard’ for the same filing period (Financial Year and Month/Quarter).
• Find the tile for ‘Monthly Return GSTR-3B’ (even if you file quarterly under QRMP scheme, GSTR-3B is filed based on the chosen frequency).
• Click on ‘Prepare Online’.
• A questionnaire might appear asking about NIL return filing or specific types of supplies/purchases made during the period. Answer appropriately.
• The system will display the GSTR-3B dashboard with various tables. Much of this data might be auto-populated based on your filed GSTR-1 and the details available in GSTR-2B (for ITC).
• Review these auto-populated figures carefully:
  • Table 3.1: Details of Outward Supplies and inward supplies liable to reverse charge.
  • Table 3.2: Details of inter-state supplies made to unregistered persons, composition dealers, and UIN holders.
  • Table 4: Eligible ITC (Input Tax Credit) – usually auto-populated from GSTR-2B. Verify this against your purchase records. Add any ITC not auto-populated if eligible (e.g., on imports). Ensure you do not claim ineligible ITC.
  • Table 5: Details of exempt, nil-rated, and non-GST inward supplies.
  • Table 5.1: Interest and late fee payable (auto-calculated if applicable).
• Make necessary manual entries if required (e.g., details of inward supplies liable to reverse charge, ineligible ITC reversal).

Step 8: Offset Liability and Make Payment (if applicable)

• Once all details in GSTR-3B are confirmed, click ‘Save GSTR-3B’ and then ‘Proceed to Payment’.
• The system will display your total tax liability (CGST, SGST/UTGST, IGST, Cess), the available ITC (from your credit ledger), and the balance in your cash ledger.
• The system shows how the liability is proposed to be offset: first using available ITC, and the remaining balance using cash. Review this carefully.
• If the available ITC and cash ledger balance are insufficient to cover the tax liability, you need to pay the deficit. Click ‘Create Challan’.
• The challan (PMT-06) will be generated with the required tax amounts. Choose your payment method (Net Banking, Credit/Debit Card, NEFT/RTGS, Over the Counter) and complete the payment.
• After successful payment, the cash ledger balance will be updated. Return to the payment screen. The system will now show sufficient balance to offset the liability.

Step 9: File GSTR-3B

• After ensuring tax liability is fully offset (either through ITC, cash payment, or both), the ‘Proceed to File’ button will be active on the payment page. Click it.
• Tick the declaration checkbox.
• Select the Authorized Signatory from the dropdown list.
• Click either ‘File GSTR-3B with DSC’ or ‘File GSTR-3B with EVC’.
• Authenticate using your DSC or the EVC OTP.
• On successful filing, an ARN will be generated. Your GSTR-3B is now filed. This completes the core GST filing guide for businesses.

Step 10: Download Filed Returns

• It’s good practice to keep records. Navigate back to ‘Services’ > ‘Returns’ > ‘View Filed Returns’.
• Select the period and search. You can download PDF copies of your filed GSTR-1 and GSTR-3B for your records.

Understanding Different Types of GST Returns

While GSTR-1 and GSTR-3B are the most common, it’s good to be aware of other return types, as different taxpayers might have different filing obligations.

Here are some key returns relevant to our target audience:

• GSTR-1: Filed monthly or quarterly (under the QRMP scheme) to declare details of all outward supplies (sales) made during the period.
• GSTR-3B: A monthly summary return where taxpayers declare their summary GST liabilities, claim ITC, and pay the net tax due. (Filed quarterly by QRMP taxpayers, but payment is monthly).
• (Optional) GSTR-4: Filed annually by taxpayers registered under the Composition Scheme. They also need to pay tax quarterly via Form CMP-08.
• (Optional) GSTR-9: The Annual Return, consolidating information furnished in monthly/quarterly returns during the financial year. Required for taxpayers with turnover above a certain threshold (currently ₹2 crore, but subject to change). GSTR-9C is a reconciliation statement applicable for turnover above ₹5 crore.

Always check the official GST portal or consult with a tax professional to confirm which returns apply to your specific business based on turnover, registration type, and scheme chosen. This information is crucial for anyone needing a GST return online guide Bangalore or elsewhere.

Common Mistakes to Avoid When You File GST Returns Online

Errors in GST filing can lead to notices, penalties, and hassles. Here are some common pitfalls to watch out for:

• Incorrect Invoice Details: Mismatches in invoice numbers, dates, values, or GSTINs, especially in B2B transactions reported in GSTR-1. This can cause issues for your recipient claiming ITC.
• Delay in Filing: Missing the due dates attracts late fees and interest. Consistent delays can impact your compliance rating.
• Errors in ITC Claims: Claiming ITC for ineligible items (like blocked credit), claiming excess ITC than available in GSTR-2B, or forgetting to reverse ITC as required (e.g., for non-payment to suppliers within 180 days).
• Mismatch between GSTR-1 and GSTR-3B: Discrepancies between the total turnover declared in GSTR-1 and the summary figures reported in GSTR-3B can trigger scrutiny from the tax department.
• Ignoring GSTR-2A/2B Reconciliation: Failing to regularly reconcile your purchase records with the auto-populated data in GSTR-2B can lead to incorrect ITC claims. GSTR-2B is the key statement for determining eligible ITC for a period.
• Incorrect HSN/SAC Codes: Using wrong HSN (Harmonized System of Nomenclature) codes for goods or SAC (Services Accounting Codes) for services can lead to classification disputes and incorrect tax rates being applied.

Avoiding these mistakes can ensure smooth compliance, much like our Ultimate Guide to GST Registration for Small Businesses ensures clarity for new registrants.

GST Return Filing Deadlines and Penalties

Timeliness is critical in GST compliance. Missing deadlines can be costly.

Key Due Dates

While these are the general deadlines, always verify the latest dates on the official GST portal or CBIC website, as they can be subject to change via notifications.

• GSTR-1:
  • Monthly Filers: 11th of the next month. (e.g., GSTR-1 for May is due by June 11th).
  • Quarterly Filers (QRMP Scheme): 13th of the month following the end of the quarter. (e.g., GSTR-1 for the April-June quarter is due by July 13th).
• GSTR-3B:
  • Monthly Filers: 20th of the next month. (Some smaller taxpayers might have staggered due dates of 22nd or 24th based on their state/UT – check notifications).
  • Quarterly Filers (QRMP Scheme): Tax payment via PMT-06 is due by the 25th of the month following the first two months of the quarter. The quarterly GSTR-3B is due by the 22nd or 24th of the month following the quarter end (based on state/UT).

Penalties for Late Filing

Failing to file GST returns online by the due date attracts penalties:

• Late Fee:
  • A late fee is levied per day of delay, per Act (CGST and SGST/UTGST), calculated from the due date until the return is filed.
  • For returns other than Annual Returns (like GSTR-1, GSTR-3B):
    • ₹50 per day (₹25 CGST + ₹25 SGST/UTGST) for returns with tax liability.
    • ₹20 per day (₹10 CGST + ₹10 SGST/UTGST) for NIL returns (returns with no tax liability).
  • These fees are subject to maximum caps based on turnover – check current notifications for exact caps.
• Interest: If you have tax liability and file late, interest is payable at 18% per annum on the outstanding tax amount, calculated from the due date until the date the tax is actually paid.
• Other Consequences: Persistent non-filing can lead to:
  • Blocking of e-way bill generation.
  • Your recipients being unable to claim ITC based on your invoices.
  • Lowering of your GST compliance rating.
  • Potential cancellation of GST registration after due process.

Frequently Asked Questions (FAQs)

Q1: Can I file GST returns myself, or do I need a professional?

Answer: You absolutely can file GST returns online yourself using the official GST portal, especially if your transactions are straightforward and you understand the process outlined above. However, for businesses with complex transactions, numerous invoices, or specific compliance needs (like export/import, reverse charge, etc.), hiring a professional like TaxRobo is highly recommended. Professionals ensure accuracy, help optimize ITC claims, keep track of changing rules, and save you valuable time, minimizing the risk of errors and penalties.

Q2: What is a NIL GST return, and do I still need to file it?

Answer: A NIL return is a GST return filed for a tax period during which you had absolutely no transactions – no sales (outward supplies), no purchases (inward supplies), no tax liability, and no Input Tax Credit (ITC) to claim or carry forward. Yes, it is mandatory to file a NIL return if you are registered under GST, even if there was zero business activity. Failure to file a NIL return by the due date will still attract late fees (though at a lower rate). The process to file GST returns online for NIL filings is simpler and quicker on the GST portal.

Q3: Can I revise a GST return after filing?

Answer: Currently, under the Indian GST law, filed GSTR-1 and GSTR-3B returns cannot be revised. If you discover a mistake (e.g., an incorrect invoice reported, or a sale missed) after filing, you generally need to correct it in the return of a subsequent tax period. For instance, incorrect details in a GSTR-1 invoice can be amended in the next month’s/quarter’s GSTR-1. Omissions can also be reported later. This makes accurate initial filing extremely important.

Q4: Is the online GST filing process different for different cities like Delhi, Mumbai, Bangalore, Chennai, or Hyderabad?

Answer: No, the process to file GST returns online is standardized across India. GST is governed by central laws (CGST Act, IGST Act) and corresponding state/UT laws (SGST/UTGST Acts) that are largely harmonized. The filing happens through the single, common national GST Portal (https://www.gst.gov.in/). Therefore, the step-by-step GST filing procedure India described in this guide applies equally whether your business operates in Delhi, Mumbai, Bangalore, Chennai, Hyderabad, or any other part of the country.

Q5: What is the difference between GSTR-2A and GSTR-2B?

Answer: Both GSTR-2A and GSTR-2B relate to Input Tax Credit (ITC) and are auto-generated based on the GSTR-1 filed by your suppliers.

• GSTR-2A: This is a dynamic, near real-time statement. It gets updated whenever a supplier uploads invoice details for supplies made to you. Because it’s dynamic, the figures can change throughout the month until the GSTR-1 filing deadline.
• GSTR-2B: This is a static statement generated for each tax period (monthly or quarterly for QRMP taxpayers) after the GSTR-1 filing due date (13th of the next month). It reflects the ITC available to you for that specific period based on the GSTR-1 filed by your suppliers by the cut-off date.

Crucially, GSTR-2B is the primary statement taxpayers should refer to for determining their eligible ITC when filing their GSTR-3B. It provides a stable view of ITC for the period, helping prevent excess or duplicate claims. Regular reconciliation of your purchase records with GSTR-2B is essential.
