GSTR – 1: Return of Outward supply

Why to file GSTR 1:

The need for filing GSTR 1 arises from section 37 of the CGST act and same is reproduced below:

Every registered person, other than:

  • An Input Service Distributor,
  • A non-resident taxable person and
  • A person paying tax under the provisions of section 10 or
  • A person paying tax under section 51 (Person deducting TDS) or
  • A person paying tax under section (Person collecting TCS) 52,
  • A person mentioned under section 14 of IGST act (supplier of online information and database access or retrieval services).

shall furnish, electronically, in such form and manner as may be prescribed, the details of outward supplies of goods or services or both effected during a tax period

  • on or before the 10th day of the month succeeding the said tax period and

such details shall be communicated to the recipient of the said supplies within such time and in such manner as may be prescribed:

Provided that the registered person shall not be allowed to furnish the details of outward supplies during the period from the 11th day to the 15th day of the month succeeding the tax period:

Provided further that the Commissioner may, for reasons to be recorded in writing, by notification, extend the time limit for furnishing such details for such class of taxable persons as may be specified therein. Hence, commissioner has extended the time limit for the months of July and August months

Provided also that any extension of time limit notified by the Commissioner of State tax or Commissioner of Union territory tax shall be deemed to be notified by the Commissioner

Hence, all taxable suppliers are liable to file GSTR 1 except those mentioned above including those cases where there is no sales in the relevant taxing month.

Meaning of details of outward supplies:

“details of outward supplies” shall include details of:

  1. Invoices,
  2. Debit notes,
  3. Credit notes and
  4. Revised invoices

Issued in relation to outward supplies made during any tax period

Importance of GSTR 1:

Normally every registered person required to furnished / validate following returns:

Return Forms GSTR – 1 GSTR – 1A GSTR – 2 GSTR – 2A GSTR -3
Activity recorded Outward supply Auto Drafted Inward Supply Auto Drafted GST Payment
Outcome GST liability Revise return ITC allowed Reconciled Monthly return
Basis of preparation Sales Invoice issued to recipient / consumer GSTR 2, 4 & 6 Part A, Part B and Part C of FORM GSTR-2A GSTR -1 of the corresponding suppliers from whom purchases are made GSTR 1 and GSTR 2

Thus, every other return except GSTR 1 is auto populated and needs to be validated by taxable registered person. Thus, every care must be made before filing the form as it would directly impact our taxable liability under
GSTR – 3.
