Many business owners think GST return filings, GSTR 1 filings are complicated. But once you understand what information is needed, how to use automations for reports, how GST Portal works, and how to File GSTR 1 Online then process becomes much easier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">GSTR-1 contains details of goods and services your business has sold during particular tax period. Registered taxpayers generally need to report their sales invoices, credit notes, debit notes, exports, advances and other applicable outward supply details through GSTR-1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide explains how to file GSTR 1 online and how <a href=\"https:\/\/invocreto.com\/\">invoicing software<\/a> makes filing process easier.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is GSTR 1?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">GSTR 1 is GST return statement used to report taxpayer&#8217;s outward supplies (sales) of goods and services made by a registered taxpayer under the Goods and Services Tax (GST) regime in India. For small business, this means reporting sales made during the month or quarter, depending on filing frequency applicable to business.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It records all sales transactions, including Business-to-Business (B2B) invoices, Business-to-Consumer (B2C) sales, exports, and credit\/debit notes allowing the government to track outward tax liability. It also helps buyers claim their Input Tax Credit (ITC) as the data auto-populates into their GSTR-2B.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The information reported in GSTR 1 can include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sales made to registered businesses, also called B2B supplies<\/li>\n\n\n\n<li>Applicable sales to unregistered customers, or B2C supplies<\/li>\n\n\n\n<li>Export supplies<\/li>\n\n\n\n<li>Credit notes and debit notes<\/li>\n\n\n\n<li>Amendments to previously reported invoices<\/li>\n\n\n\n<li>Advances received and their adjustments, where applicable<\/li>\n\n\n\n<li>Nil-rated, exempt, and non-GST supplies<\/li>\n\n\n\n<li>HSN\/SAC-wise summary of outward supplies<\/li>\n\n\n\n<li>Details of documents issued, where applicable<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Businesses should still review the information carefully before filing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who Needs to File GSTR 1?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Normal and casual registered taxpayers making outward supplies of goods or services are required to file GSTR 1 electronically. But there are exceptions. For example, taxpayers such as composition taxpayers and certain other categories covered by separate provisions do not file GSTR-1 in normal manner.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are unsure whether GSTR 1 applies to your business, consult indiacorporates about <a href=\"https:\/\/indiacorporates.com\/services\/gst-filing\" rel=\"noopener\">GST return filings<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do I need to file GSTR 1 if there are no sales?<\/strong><br>Yes. GSTR 1 is generally required even when there is no business activity for the tax period. In such a situation, Nil GSTR 1 may need to be filed. So, having no sales does not automatically mean you can ignore the return.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">GSTR 1 Due Date<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For taxpayers filing GSTR-1 monthly, the normal due date is generally the 11th day of the following month.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For quarterly filers, GSTR-1 is generally due on the 13th day of the month following end of the quarter under the current quarterly filing process. Government notifications can change due dates, so businesses should always check the GST Portal for the applicable period.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>For example:<\/strong><br>January sales \u2192 monthly GSTR-1 generally due by February 11<br>April\u2013June quarter \u2192 quarterly GSTR-1 generally due by July 13<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always check the actual due date displayed on the GST Portal because the government may extend filing dates for specific periods or locations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Monthly vs Quarterly GSTR 1 Filing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Small businesses can generally file GSTR 1 either monthly or quarterly, depending on their eligibility and filing choice. Under the QRMP (Quarterly Return Monthly Payment) Scheme, eligible taxpayers can file GSTR-1 and GSTR-3B quarterly while paying their tax dues monthly.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Point<\/td><td><strong>Monthly GSTR-1 Filing<\/strong><\/td><td><strong>Quarterly GSTR-1 Filing (QRMP)<\/strong><\/td><\/tr><tr><td>Who can choose it?<\/td><td>Taxpayers who are required to file monthly returns and eligible taxpayers who choose monthly filing<\/td><td>Eligible taxpayers under the QRMP Scheme<\/td><\/tr><tr><td>Turnover eligibility<\/td><td>Monthly filing is available\/required where the taxpayer does not opt for quarterly filing or is not eligible for QRMP<\/td><td>Generally available to taxpayers with aggregate annual turnover up to \u20b95 crore, subject to QRMP conditions.

Check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Invoice number<\/li>\n\n\n\n<li>Invoice date<\/li>\n\n\n\n<li>Customer name<\/li>\n\n\n\n<li>Customer GSTIN, where applicable<\/li>\n\n\n\n<li>Place of supply<\/li>\n\n\n\n<li>Taxable value<\/li>\n\n\n\n<li>GST rate<\/li>\n\n\n\n<li>CGST<\/li>\n\n\n\n<li>SGST\/UTGST<\/li>\n\n\n\n<li>IGST<\/li>\n\n\n\n<li>Invoice total<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Credit and debit notes<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">If you issued any credit notes or debit notes, keep their details ready. These documents should be reported correctly in the relevant GSTR-1 sections.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Export details<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Businesses making export supplies should keep the required export invoice and shipping-related information ready, as applicable.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">HSN\/SAC details<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">GSTR-1 includes HSN\/SAC reporting requirements. The GST Portal has also introduced changes to Table 12, including separate tabs for B2B and B2C supplies and an updated <a href=\"https:\/\/invocreto.com\/tools\/hsn-code-search\">HSN\/SAC list<\/a>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Previous-period corrections<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Check whether any invoice from an earlier period needs to be amended. Correct reporting is important because mistakes in GSTR-1 can affect the buyer&#8217;s records and create reconciliation issues.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to File GSTR 1 Using Invoicing Software<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Using <a href=\"https:\/\/invocreto.com\/\">invoicing software<\/a> can make GSTR-1 filing much easier because your sales invoice data is already stored in one place. With software such as Invocreto, you can generate the <a href=\"https:\/\/invocreto.com\/\">GSTR-1 JSON report<\/a> and upload it to the GST Portal instead of entering invoices one by one.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Step 1: Create and Record Your GST Invoices<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Log in to your Invocreto account. Make sure all your sales invoices for the filing period are created in Invocreto.

(Make sure you select the correct filing period before exporting the report.)<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Step 4: Generate and Download the GSTR 1 File<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">After selecting the period, review the invoice data and click Export All. Invocreto generates the GSTR-1 report as a JSON file, which can then be used on the GST Portal. This saves you from manually entering every invoice into the GST Portal.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Step 5: Open the GST Portal<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Go to the official <a href=\"https:\/\/www.gst.gov.in\/\" rel=\"noopener\">GST Portal<\/a> and log in with your GST credentials.

The GST Portal processes the uploaded data and shows the relevant details in GSTR-1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Check the uploaded data<br><\/strong>Open the GSTR 1 details and verify the invoices, taxable values, GST amounts, credit\/debit notes and other applicable information.

The key is to keep your invoice records accurate and organised throughout the tax period. Start by collecting all sales invoices, checking GSTINs, confirming GST rates and place of supply, recording credit and debit notes, and reviewing HSN\/SAC information. Then log in to the GST Portal, select the correct return period, enter or upload your data, review the summary, and complete the filing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For small businesses, the best approach is not to wait until the GSTR 1 due date. Make GST record-keeping part of your regular billing process. With organised invoices and the right tools, GSTR-1 filing can become a simple monthly or quarterly routine instead of a last-minute task.
