GSTR-1 is a crucial return that regular Goods and Services Tax (GST) taxpayers in India must file, either on a monthly or quarterly basis. This return provides a detailed account of a taxpayer's sales transactions, which is vital for compliance with the GST regulations. Essentially, if you're a registered GST taxpayer, it's your responsibility to file GSTR-1 to report your outward supplies. This ensures that your tax liabilities are accurately reflected, and helps maintain transparency in the tax system.

One significant update as of June 11, 2025, involves the GST Network's clarification on B2C supplies in Table 12 of GSTR-1. Previously, taxpayers faced issues when they had no B2B supplies and left the HSN Summary (Table 12A) blank. The GST department now requires at least one entry in Table 12A, allowing taxpayers to input any HSN code and mark other fields as '0'. This change is designed to simplify the filing process for those primarily engaged in B2C transactions, making it easier to stay compliant.

Filing GSTR-1 requires you to include several essential components. First, you need your GST Identification Number (GSTIN). Next, your legal entity details will automatically populate when you log in to the GST Portal. You'll also need to provide the Application Reference Number (ARN) and its submission date. Other critical sections include reporting B2B and B2C supplies, detailing zero-rated and deemed exports, and reporting nil-rated or exempt supplies. Additionally, don't forget the amendments section, where you can correct previously reported data as needed.

In GSTR-1, B2B supplies are reported in sections 4A and 4B. For section 4A, you need to provide invoice-wise details of B2B supplies that are not subject to reverse charge, including those made through e-commerce platforms. Section 4B is for outward supplies that attract a reverse charge. For B2C supplies, if your sales to unregistered individuals exceed Rs.2.5 lakh (which is now adjusted to Rs.1 lakh), detailed reporting is required. Ensure you summarize all B2C sales below this threshold in the appropriate section to maintain compliance.

Yes, you can amend your GSTR-1 return after submission. This includes making changes to previously reported data for B2B and B2C transactions, as well as exports. However, it’s important to note that corrections to invoices already accepted by the recipient cannot be made, as these will automatically reflect in the supplier's GSTR-1. Timely amendments are crucial to ensure that your tax records are accurate, so keep an eye on your reports and make necessary changes promptly.

If you do not have a GST Identification Number (GSTIN), you can use a provisional ID for the purpose of filing your GSTR-1 return. However, it's recommended that you apply for a GSTIN as soon as possible, as having a GSTIN is essential for compliance with the Goods and Services Tax framework in India. The GSTIN serves as your unique identifier in the tax system, and it helps streamline your filing process. You can apply through the GST Portal or consult a tax professional for assistance.

To ensure compliance when filing your GSTR-1, stay updated with the latest changes in GST regulations and requirements. Utilize software tools specifically designed for GST filing to streamline the process and minimize errors. Regularly review your sales transactions to ensure accurate reporting of B2B and B2C supplies. It may also be beneficial to consult with a tax professional or legal advisor who can provide guidance tailored to your specific situation. By being proactive and organized, you can effectively manage your GSTR-1 submissions and avoid penalties.
