What is GSTR 1?


GSTR 1 prescribes the details to be provided by the taxpayer in relation to outward supplies made to the buyer for the relevant period. GSTR 1 needs to be filed by every taxpayer except Composition Scheme taxpayers, Non-Resident Foreign taxpayers, TDS deductors, E-commerce Operators and Input Service Distributors as there are separate returns for them. This return is required to be filed by the 11th of the subsequent month. (Example: GSTR-1 for the transaction month of April has to be filed before 10th May).

The government has notified new GST Return formats in this regard and removed the mandatory requirement to quote HSN codes for goods and SAC codes for services in each table. The GST Return Formats have been updated to ease the process and simplify compliance for taxpayers under GST.
