One of the most important compliances under GST is filing GST returns. GSTR 3B is a declaration filed by the registered business entity on a monthly basis as a summary of inward and outward supplies. The GST liabilities must be declared in a given tax period. So if you are a registered GST dealer, you are required to file it every month (by the 20th).

Some important points to keep in mind with regard to the tax:

  • It cannot be amended.
  • Separate GSTR 3B has to be filed for separate GSTIN.
  • Payment of the tax liability of it must be done by the last date of filing it.
  • NIL returns must be present in the filing.

Applicability For Filing GSTR 3B

All registered dealers must file the GSTR 3B except composition dealers, input supply distributors, online information suppliers, non-resident taxable individuals, and those whose business consists of online database or retrieval services.

Due Date

The GSTR 3B must be filed monthly, and its submission must be made by the 20th date of the succeeding month.

Fine and late fee provisions are there for delays and non-compliance of filing the form. An interest of 18% P.A. is to be paid on the due tax amount as a result of any delay. ₹50 per day as a fine is to be paid for the delay of each day. If the payment of taxes is done, but the filing of the form is done after the deadline, both interest and late fees will be levied.

Those taxpayers who have a nil tax liability for a month are subjected to a late fee of ₹20 per day for each day delayed.

Information Needed To File GSTR 3B

Total amounts of the following categories have to be noted:

  • Outward taxable supply
  • Zero-rated outward taxable supply
  • NIL rated and exempted outward taxable supply
  • Inward supply (liable to reverse-charge mechanism)
  • Non-GST outward supply
  • Interstate supply to unregistered persons, composition dealers, and UIN holders.
  • ITC available on imported goods and services
  • ITC available to inward supply liable to reverse-charge
  • Inward supply from Input Service Distributor

How is GSTR 3B manually calculated?

The amount due is a sum total of GST payable on reverse-charge, inward supplies, and outward supplies. It is calculated individually for each month, which is then filed through the GSTR 3B form and then paid as per the due dates.

Can I file GST myself?

Under the new GST regime, filing tax returns has turned into an automated process. It can be filed online using the software provided by Goods and Service Tax Network (GSTN) which will auto-populate the details on each GSTR form.

Is GST filing mandatory?

It is required to be filed by all taxpayers registered under GST. However, there are few exceptions such as taxpayers who opted for the composition scheme, casual taxable persons, input service distributors, non-resident taxable persons, and persons paying TDS under section 51 of the CGST Act.
