This easy-to-understand guide will walk you through the entire GST return filing process on the GST Portal – step by step.


📌 What You Need Before Filing

Before you get started, keep the following ready:

  • Your GST Portal login credentials (GSTIN, username, password)

  • All invoices for sales and purchases during the return period

  • Access to DSC (Digital Signature Certificate) or OTP/EVC for verification

  • Bank details, if you’re expecting a refund


🧾 Step-by-Step Process to File GST Returns Online

Step 1: Visit the GST Portal

Go to the official website: https://www.gst.gov.in


Step 2: Login to Your Account

Use your GSTIN, username, and password to log in. Complete the CAPTCHA and hit Login.


Step 3: Access the Returns Dashboard

Click on Services > Returns > Returns Dashboard.
Then choose your Financial Year and Return Filing Period, and click Search.


Step 4: Choose the Return Form

You will now see the list of return forms applicable to your business. These may include:

  • GSTR-1 – for outward supplies

  • GSTR-2A / GSTR-2B – auto-generated inward supply data

  • GSTR-3B – summary return of tax liability and ITC

Click on the relevant form and choose Prepare Online.


Step 5: Fill in Return Details

Enter the required data such as:

  • Sales and outward supply details

  • Purchase and inward supply details

  • Input Tax Credit (ITC) claimed

Click Save after entering all information.


Step 6: Submit the Return

After saving, click Submit.
The return status will change to “Submitted” once the portal processes the data.


Step 7: Pay Your GST Liability

Click Payment of Tax.
You’ll see your available cash and credit balances.

Use the “Offset Liability” option to use your ITC and pay the remaining amount in cash, if required.


Step 8: File the Return

Tick the declaration checkbox, select the authorized signatory, and click either:

  • File with DSC, or

  • File with EVC

Once done, your return is officially filed.


Step 9: Download the Acknowledgment

Keep this safe for your records.
