How to Upload GSTR-1 JSON to the GSTN Portal

Once you have prepared and downloaded the GSTR-1 JSON file from EZTax.in GST Accounting, the final step is to upload it to the GSTN (Goods and Services Tax Network) portal for official filing. The GSTN portal is the government's official platform where all GST returns must be submitted. This guide walks you through the entire upload and filing process.

Follow these steps to access the GSTN portal and prepare for GSTR-1 upload:

1. 1
   Visit GSTN Website

   Open your web browser and navigate to the official GST portal at https://www.gst.gov.in/. You may also access this directly through EZTax.in which provides a direct link to the portal.

2. 2
   Login with GSTIN

   Click on the login section and enter your GSTIN (Goods and Services Tax Identification Number). This is a 15-digit unique identifier assigned to your business by the tax authorities. Use your registered username and password to access your GST account.

3. 3
   Verify OTP

   The portal will send a One-Time Password (OTP) to your registered mobile number or email. Enter this OTP to complete the authentication process and access your GSTN account dashboard.

4. 4
   Navigate to GSTR-1

   Once logged in, navigate to the "Returns" section and select "GSTR-1" from the available return types. The portal will display options for filing new returns or viewing filed returns for different periods.

The upload process involves several key steps. Follow this sequence for a successful submission:

1. 1
   Select Return Period

   Choose the month or quarter for which you are filing the GSTR-1 return. The portal displays all open periods for filing along with their respective due dates.

2. 2
   Upload JSON File

   Click on the "Upload" button and select your GSTR-1 JSON file downloaded from EZTax.in. The file must be in the exact JSON format as generated by EZTax.in for compatibility with the GSTN system.

3. 3
   System Processing

   The GSTN portal will process your uploaded JSON file. This typically takes a few seconds to complete. During processing, the portal validates the file format and structure to ensure compliance with GST regulations.

4. 4
   Review Uploaded Data

   After processing, the portal displays a summary of the data imported from your JSON file. This includes invoice counts, total taxable values, and tax summaries by invoice type (B2B, B2C, Credit/Debit Notes, etc.). Review this carefully before proceeding.

The GSTN portal performs automatic validation of your uploaded JSON file. This includes:

• Format Validation: Confirms the file is a valid JSON format recognized by GSTN
• Data Structure Check: Verifies all required fields are present and in correct format
• GSTIN Verification: Cross-references customer and supplier GSTINs against GST database (may show as unregistered if they are newly registered)
• HSN/SAC Validation: Checks HSN (Harmonized System of Nomenclature) and SAC (Service Accounting Code) codes for accuracy
• Tax Calculation Review: Validates that tax amounts are correctly calculated based on HSN/SAC codes and applicable rates

If you encounter errors during upload, follow these common troubleshooting steps:

Once your JSON file is validated and all issues are resolved, proceed with return finalization:

• Final Review: Review the data summary one last time before submission. This is your last opportunity to make changes.
• Submit Return: Click the "Submit" button to officially file your GSTR-1 return with GSTN. The return status changes to "Filed".
• Digital Signature: Some transactions may require DSC (Digital Signature Certificate) authentication. Use your certified DSC to authorize the filing.
• Download Receipt: After successful filing, the portal provides a unique filing receipt/acknowledgment number. Download and save this for your records.
• Confirmation Email: GST portal sends a confirmation email with the filing details and acknowledgment number to your registered email address.
