What is GSTR-3B?
GSTR-3B is a self-declared return where you report:
-
Your outward supplies (sales or services you provided).
-
Your inward supplies (purchases or services you received).
-
The GST you owe (output tax) and the GST credit you can claim (input tax credit, or ITC).
-
The net tax you need to pay to the government after adjusting the credit.
It’s a temporary return introduced to make GST compliance easier, but it has become a regular requirement for most taxpayers.
Who Needs to File GSTR-3B?
-
All regular GST-registered businesses (except those under the Composition Scheme or certain specific cases like Input Service Distributors or non-resident taxpayers).
-
Even if you had no transactions in a month, you still need to file a nil return.
What Information Goes into GSTR-3B?
The form has sections for:
-
Outward Supplies (Sales):
-
Details of taxable sales (goods or services) and the GST collected (CGST, SGST, or IGST).
-
Includes zero-rated supplies (like exports) and exempt/nil-rated supplies.
-
-
Inward Supplies (Purchases):
-
Details of purchases where you paid GST and can claim ITC.
-
You report the GST you’re eligible to claim as a credit.
-
-
Input Tax Credit (ITC):
-
The GST you paid on purchases that you can use to offset the GST you owe on sales.
-
You also report any ITC you’re reversing (e.g., if you used goods for non-business purposes).
-
-
Tax Payable:
-
The total GST you owe (output tax minus ITC).
-
If your ITC is more than your output tax, you carry forward the excess credit.
-
-
Tax Payment:
-
Details of the tax you’re paying in cash or using ITC.
-
Includes any interest or penalties, if applicable.
-
When is GSTR-3B Filed?
-
Deadline: Usually the 20th of the next month for the previous month’s transactions (e.g., June 20, 2025, for May 2025, as mentioned in your GST compliance list).
-
For businesses under the QRMP scheme (Quarterly Returns Monthly Payment), the deadline may vary slightly, but most still file GSTR-3B monthly.
How to File GSTR-3B?
-
Log in to the GST Portal (www.gst.gov.in) (www.gst.gov.in).
-
Fill in the details in the GSTR-3B form (sales, purchases, ITC, tax payable).
-
Verify the details and submit the return.
-
Pay any tax owed (if not fully covered by ITC) through the portal.
-
File the return with a digital signature or EVC (Electronic Verification Code).
Why is GSTR-3B Important?
-
Compliance: Filing GSTR-3B on time keeps you compliant with GST laws and avoids penalties (₹50/day for regular returns, up to ₹5,000, as of 2025).
-
Tax Payment: It ensures you pay the correct GST to the government.
-
Input Tax Credit: It allows you to claim credit for GST paid on purchases, reducing your tax burden.
-
Audit Trail: It helps the government track your GST transactions and ensures transparency.
Key Points to Remember:
-
Accuracy: Double-check your sales and purchase details to avoid errors. Mistakes can lead to notices from the GST department.
-
Form 26AS Link: GSTR-3B details should match your Form 26AS (for TDS) to avoid discrepancies.
-
No Revisions: Once filed, GSTR-3B can’t be revised, so be careful before submitting.
-
Late Filing: If you miss the deadline, you’ll face late fees and interest (18% per year on unpaid tax).
Example:
Let’s say you run a shop in May 2025:
-
You sold goods worth ₹1,00,000 and collected ₹18,000 GST (18% GST rate).
-
You bought supplies worth ₹50,000 and paid ₹9,000 GST.
-
In GSTR-3B, you report:
-
Output tax (GST on sales): ₹18,000.
-
Input tax credit (GST on purchases): ₹9,000.
-
Net tax to pay: ₹18,000 – ₹9,000 = ₹9,000 (in cash or from ITC balance).
-
Late Fee & Penalty for GSTR-3B
A late fee is charged for filing GSTR-3B of a tax period after the due date. It is levied as follows:
- Rs. 50 per day of delay
- Rs. 20 per day of delay for taxpayers having nil tax liability for the month
In case the GST dues are not paid within the due date, interest at 18% per annum is payable on the amount of outstanding tax to be paid.
