Filing GSTR-1 | You have to avoid these mistakes

As noted above, there is no facility provided under GST to amend the GSTR-1 return. Accordingly, it is important to be more precise while GSTR-1 filing.

Following are the lists of some common errors/ mistakes which the registered person should avoid while furnishing return in Form GSTR-1.

Non-filing of NIL GSTR-1 return

During the relevant period in case there are no transactions to be reported in GSTR-1, there is always a tempting misconception that GSTR-1, being NIL, is not required to be furnished for that relevant tax period.

However, importantly, filing of GSTR-1 return is mandatory even in case there are no transactions during the relevant tax period.

Resultantly, due to the non-filing of the NIL GSTR-1 return, the registered person will end up paying unwanted late fees. In order to avoid the same, the registered person should always keep in mind that filing of GSTR-1 is unavoidable/ mandatory even in case there are no transactions (NIL).

Furnishing of the information under the incorrect head

Details of outward supplies carried out in the relevant tax period are required to be furnished in GSTR-1 based on the type of outward supplies like

  • Taxable outward supplies to registered persons;
  • Taxable outward supplies to unregistered persons;
  • Zero-rated supplies and deemed exports; etc.

It is important to provide the details of outward supplies under the correct GST head. In the general case, it is noted that the registered person is concerned only about the correct reflection of total outward supplies in GSTR-1.

 Notably, there are several occasions where the registered person has provided the details of outward supplies under the wrong head. One such common mistake is reflecting wrong details under zero-rated supplies and deemed exports. Such mistake of mentioning details of outward supplies under the wrong head should be avoided while filing a GSTR-1 return.

Errors at the time of uploading invoice-wise data in GSTR-1

While furnishing invoice details in GSTR-1, the registered person needs to upload the details invoice-wise like date of invoice; invoice number; place of supply; GST rates; etc.

Tediously, invoice-wise details are to be furnished manually and hence there are high chances of committing mistakes while furnishing such important details.

Importantly, there is no facility available under GST to amend/ modify the errors committed while filing GSTR-1. Hence, it is important to be extra careful while furnishing invoice-wise details

Furnishing details of aggregate turnover

Section 2(6) of the Central Goods and Services Tax Act, 2017 defines the term ‘aggregate turnover’. Accordingly, it means all taxable supplies, export of goods/ services, exempt supplies and inter-state supplies of a person having the same PAN (to be computed on all India basis), however, excludes central tax, state tax, integrated tax, union territory tax and GST compensation cess.

Notably, at column 3(a) of GSTR-1, the registered person is required to furnish details of aggregate turnover in the preceding financial year. Accordingly, the registered person should not commit any error while furnishing such details.
