Missed a GSTR-1 or GSTR-3B due date? A GST late fee calculator lets you work out the exact penalty you owe before you file, so there are no surprises on the GST portal. This guide walks you through using the calculator on ardhorajiya.com in under a minute.
Why GST Late Fees Add Up Quickly
Every day of delay in filing GSTR-1 or GSTR-3B attracts a fixed late fee under Section 47 of the CGST Act, split equally between CGST and SGST. Returns with a tax liability are charged ₹50 per day (₹25 CGST + ₹25 SGST), while Nil returns are charged ₹20 per day (₹10 CGST + ₹10 SGST), capped at ₹500. Composition dealers filing GSTR-4 face the same ₹50/₹20 per day rates, with regular filings capped at ₹2,000. Because the fee is calculated per day, even a short delay in a busy month can turn into a meaningful amount by the time you get around to filing.
Step-by-Step: Using the Calculator
- Choose your return type – select GSTR-1 / GSTR-3B for regular monthly or quarterly filings, or GSTR-4 if you’re a composition dealer filing your annual return.
- Select filing type – toggle to “Regular” if the return has a tax liability, or “Nil return” if there were no sales, purchases, or tax payable for that period.
- Enter the due date – this is the original deadline for that specific return period, as shown on the GST portal.
- Enter the filing date – pick the date you actually filed, or the date you’re planning to file. The calculator instantly works out the number of days delayed.
The results update instantly as you fill in each field – there’s no submit button to click.
Reading Your Results
Once you enter both dates, the calculator shows the number of days delayed along with the late fee split between CGST and SGST, plus the total. For Nil returns and GSTR-4, a bar underneath the day count also shows how close your fee is to the statutory cap. For regular GSTR-1/3B filings, the fee accrues at ₹50 per day for as long as the return stays unfiled; keep in mind the law itself caps this at anywhere between ₹2,000.
If you filed on or before the due date, the calculator simply confirms there’s no late fee to pay, so you can move on with confidence.
Quick FAQs
Does the late fee apply even to Nil returns?
Yes. Even with zero tax liability, a Nil GSTR-1 or GSTR-3B filed late attracts ₹20 per day, capped at ₹500.
Is IGST included in the late fee calculation?
No, the late fee is levied only under the CGST and SGST Acts.
Can the late fee be paid using Input Tax Credit?
No. Late fees must be paid in cash through the electronic cash ledger; ITC cannot be used for this payment.
