All normal and casual registered taxpayers making outward supplies of goods and services with a yearly revenue exceeding the specified threshold limit must register for GST. The registered individuals or entities must follow the procedures for tax collection, payment of the taxes collected to the government, and periodic return filing through the GST portal as part of the compliance process.

The GST returns cover sales, purchases, GST received and paid, and input tax credits claimed. Ensuring the correct person gets credit is possible by accurately filing returns. The GSTR-1 is one such important return that has details on every sale the business made in the tax year. A report on each transaction made under the sales category in the preceding month is included in this return. All registered taxpayers (apart from composition dealers, input service distributors, non-resident taxable individuals, and those required to collect TDS and TCS) must file GSTR-1 either monthly or quarterly, depending on their turnover.

What is GSTR-1?

All registered taxpayers are required by Section 37 of the CGST Act to provide information about outward supplies through the filing of GSTR-1. It is a monthly return that must be electronically filed on the government-provided GST portal and includes information on all outward supplies of goods and services. It needs to be submitted by the 10th of the following month, following the conclusion of the relevant tax month. GSTR-1 is the sales report or sales summary for taxpayers.

Information to be provided in GSTR-1

The details that the taxpayer has to provide while filing GSTR-1 are as follows:

  • Invoice details of supplies to registered persons and summarize the details of supplies to unregistered persons.
  • Invoice details of interstate supplies with invoice values greater than R.25000/-.
  • Details of credit and debit notes issued by the supplier against invoices.
  • Details of the export of goods and services, including deemed exports.
  • Summary details of advances received related to future supply and their adjustment.

Generation of sales summary in GSTR-1

After entering all the details of sales in the return, the taxpayer can generate the summary by clicking on the ‘generate summary’ option provided in the portal. By clicking the ‘preview’ option, the taxpayer can view the summary to verify the correctness of the invoice details entered before submitting the return.

The HSN-wise summary of outward supplies in GSTR-1 will reflect the number of invoices added along with total value, total taxable value, and total tax liability.

Generating the sales summary is important to ensure that the supplier has collected accurate tax from the customers and has remitted the said tax to the government within the time specified under GST. Late payment or non-payment of tax will result in late fees and other penalties. It is also an important document for recipients to compute and claim their eligible input tax credit (ITC). Timely and accurate filing of GSTR-1 helps recipients claim the correct ITC.

Excel template for GSTR-1

An offline tool with an Excel template is provided by GSTN to help taxpayers when there are many invoices to be reported. It is part of GSTN’s attempt to make tax compliance easy and convenient for taxpayers. The Excel template can be easily downloaded from the GST portal and used by taxpayers to report all the invoice-related data accurately.

Businesses with numerous invoices in a tax period may find it difficult to upload the individual invoices. It is costly and time-consuming. In the offline facility, the invoices can be uploaded in bulk. In the returns offline tool, the taxpayer can add up to nineteen thousand-line items and upload them to the GST portal at a time. When there is more invoice data, the returns offline tool can be used multiple times to upload it. The uploaded invoice details can be edited in the GST portal through the returns offline tool before the return is submitted for processing. This tool can also be used to view and download data in GSTR-2A by recipients. The data in GSTR-2A is auto-populated based on the returns filed by the supplier in their respective GSTR.

Taxpayers can prepare separate Excel workbook templates with different names for different GSTINs. These different files can be imported into the returns offline tool and uploaded to the GST portal. Third-party accounting or billing software can be used for invoice generation. If the Excel file generated by the third party is in the same format as provided by GSTN’s Excel workbook, the same can be uploaded. Otherwise, the third-party accounting software can generate the details in .CSV format, which can be imported into the offline tool. The CSV is a comma-separated value format. The JSON file generated through the returns offline tool can be uploaded to the GST portal by the taxpayer logging into the portal using valid credentials. After the upload is successful, the summary of the invoices uploaded is displayed.
