What is GSTR 3?

GSTR 3 is an auto-generated monthly return. It captures information from GSTR 1 (filed by seller) and GSTR 2 (filed by buyer). It contains a summary of sales and purchases during the month as well as the amount of tax liability under GST.

Who needs to file it?

  • Input Service Distributors
  • Composition Dealers
  • Non-resident taxable person
  • Persons liable to collect TCS
  • Persons liable to deduct TDS
  • Suppliers of OIDAR

Further, it is compulsory to file GSTR 3 even if there were no transactions during the month.

What is the last date for filing GSTR 3?

The last date for filing GSTR 3 has been extended to 10th November 2017 for the month of July.

Earlier due date for the month of August was 15th October which has been scrapped. The revised due date for the month of August and onward is yet to be notified.

What details do I need to provide?

There are two parts in GSTR 3. Part A consists of Columns 3 to 11 and it completely auto-populated from GSTR 1 and GSTR 2. Part B consists of Columns 12 to 15.

Below you can find detailed information about every section of GSTR 3 return.

Part A

This section is auto-populated from GSTR 1, 1A, and 2.


This section will consist of details of turnover from different activities. Turnover from exempted, nil rated, and Non-GST supplies also needs to be reported here.

Taxable supplies include regular sales to registered as well as unregistered buyers.

The second item is zero-rated supply on payment of tax. This means exports on which IGST has been paid (which is later claimed as a refund).

Zero-rated supplies without payment of tax are exports made under a bond or letter of undertaking.

Supplies to Special Economic Zones (SEZs) are deemed as exports.

Exempted goods and services are not chargeable to GST. Turnover from a supply of such items is reported here.

NIL rated items are chargeable to zero rate of tax.

Non-GST items are outside the purview of GST and turnover from supply of such items also needs to be reported here.

Tax Effect of Amendments in Respect of Outward Supplies

The main aim of this section is to keep track of any changes to invoices and the resulting changes in the tax liability.

Any changes to sales invoice will also change the amount of Input Tax Credit which may lead to excess payment of tax or even underpayment of tax.

In both cases, it is important to keep track of the changes in tax liability which is precisely what this section does.

The last step in filing GSTR 3 is to sign off the verification declaring that all information in the return is correct and does not conceal anything.

Is GSTR 3B a part of GSTR 3?

GSTR 3B is a temporary return which needs to be filed for the months of July and August.

It exempts the taxpayer from the requirement of filing 3 returns every month for the initial months of July and August.

GSTR 3B simplifies things a little and brings down the number of monthly returns from 6 to 2 for the initial 2 months. This gives considerable relief to the taxpayer.

It essentially combines the details to be filled in GSTR 1, 2, and 3 and familiarizes the taxpayer with the new return filing system.

Everyone who is liable to file GSTR 1, 2, and 3 need to file GSTR 3B.

Moreover, even after filing GSTR 3B for the months of July and August, you still need to file GSTR 3 for these two months.

If there is a difference between the liabilities declared in GSTR 3B and actual liabilities as per GSTR 3, the system will automatically update the difference. If the amount of actual liability is higher than the amount declared in GSTR 3B, then the taxpayer will need to pay this difference in amount along with interest.

How to file GSTR 3?

At present, there are two ways to file GSTR 3.

Online Filing through GST Portal

You can do this by logging onto your account on the GST common portal.

It’s an easy 4 step process.

Step 1

Log in to your account on the GST common portal.

Step 2

Fill the relevant information according to the type of return.

Step 3

Verify auto-populated information and add or edit details, if necessary.

Step 4

Digitally sign the return using a digital signature of the authorized person.

GST Suvidha Providers (GSPs)

The Suvidha Provider will prepare and upload your return using any of the above methods. You need to provide all relevant details to the Suvidha Provider to facilitate the filing of returns.

Can I revise GSTR 3?

It is not possible to revise any of the GST Returns. If there is any correction or revision, you can do it while filing the return for the next tax period. You need to make these revisions/corrections in next month’s GSTR 1 and GSTR 2 respectively.

GSTR 3 is an auto-populated return and it is not possible to make any edits to it.

What if I don’t file GSTR 3?

If you fail to file GSTR 3 on time, there is a penalty of Rs. 100 per day. Combine CGST and SGST and this penalty will reach Rs. 200 per day. There is no penalty in respect of IGST and the maximum chargeable penalty is Rs. 5000.

In case of non-filing of GSTR 3, you may also receive a default notice under section 46 of the CGST Act and will be liable to pay the tax amount along with interest on the outstanding amount.

Not only this, if you do not file GSTR 3, filing GSTR 1 for the next month will not be possible.

So, don’t be late in filing your GSTR 3 and don’t be a defaulter. Now when the due date
has been extended even further, there is plenty of time and opportunity to file your
GSTR 3 within time and with all available details.

Filing timely returns is beneficial for both you and your business. Your business gains credibility and you gain peace of mind by not having to worry about being a tax defaulter.
