GST Late Fee Calculator — GSTR-3B, GSTR-1 & GSTR-9 Penalties

GST late fee — the basics

CGST Act §47 imposes a late fee if a registered taxpayer fails to file a GST return by its prescribed due date. The fee accrues every calendar day until the return is filed.

The fee is split equally between CGST and SGST — there is no IGST component for late fees on intra-state returns (GSTR-3B, GSTR-1). The combined per-day rates are:

Return	Non-nil	Nil
GSTR-3B	₹50/day (₹25 CGST + ₹25 SGST)	₹20/day (₹10+₹10)
GSTR-1	₹50/day	₹20/day
GSTR-9 (annual)	₹200/day (₹100+₹100)	₹200/day
GSTR-4 / CMP-08	₹50/day	₹20/day

Notification 7/2023 caps

Even if the raw fee accumulates to a large number for long delays, Notification 7/2023-Central Tax (31 March 2023) places a ceiling:

Annual turnover	Cap for GSTR-3B/1	Cap for GSTR-9
≤ ₹1.5 crore	Lower of ₹2,000 or 0.04% of turnover	0.25% of turnover
₹1.5 – ₹5 crore	Lower of ₹5,000 or 0.04% of turnover	0.25% of turnover
> ₹5 crore	Lower of ₹10,000 or 0.5% of turnover	0.25% of turnover

The calculator applies these caps automatically.

Late fee vs interest — don’t confuse them

	Late fee (§47)	Interest (§50)
Trigger	Late filing of return	Unpaid tax after due date
Rate	₹20–₹200/day flat	18% p.a. on unpaid tax
Applies to nil returns?	Yes	No (no tax = no interest)
Turnover cap?	Yes (Notification 7/2023)	No

A taxpayer who has a nil return but files 60 days late owes only the late fee (₹20/day × 60 = ₹1,200, subject to cap) — no interest, since there’s no unpaid tax.

Frequently Asked Questions

Is GST late fee the same as GST interest?

No — these are two separate levies. **Late fee** (§47) is charged per day for late filing of the return itself, regardless of whether there is a tax liability. **Interest** (§50) is charged at 18% p.a. on unpaid tax for every day the tax remains unpaid after the due date. Both may apply simultaneously. This calculator computes the late fee only.

Have there been amnesty schemes for past GST late fees?

Yes. CBIC has periodically issued amnesty notifications waiving or reducing late fees for older returns. The most recent was Notification 7/2023 (effective 1-Apr-2023), which capped late fees going forward based on annual turnover. Earlier amnesties covered backlog returns from 2017–2022. Always check the latest CBIC circular for any amnesty applicable to your period.

Why does annual turnover affect the late-fee cap?

Notification 7/2023-Central Tax created three turnover tiers: ≤₹1.5 cr (cap ₹2,000 for GSTR-3B/1), ₹1.5–5 cr (cap ₹5,000), and >₹5 cr (cap ₹10,000). The logic is proportionality — smaller taxpayers face a lower absolute ceiling. GSTR-9 uses a 0.25%-of-turnover cap. The caps are total (CGST + SGST combined); each component is half.

Are CGST and SGST components filed separately?

For GSTR-3B and GSTR-1, CGST and SGST late fees are equal halves paid to Central and State authorities respectively through a single GSTN payment. You see two separate line items in the challan — but you file one return. IGST late fee does not apply to GSTR-3B/1 (only CGST + SGST).

Can a late filing fee be challenged or waived?

Automatic waiver applies only through official amnesty notifications. Otherwise, late fees are system-computed by the GSTN portal and cannot be overridden except through a refund application. If the portal charged an incorrect fee (e.g., charged non-nil rate for a nil return), raise a ticket on the GSTN helpdesk or file a refund application under §54.

What is special about GSTR-9 late fees?

GSTR-9 (annual return) attracts a higher ₹200/day fee (₹100 CGST + ₹100 SGST) — four times the monthly GSTR-3B fee. The cap is 0.25% of annual turnover. GSTR-9 is mandatory for taxpayers with annual turnover above ₹2 crore; those at ₹2 cr or below are exempt from filing GSTR-9 (though they may file voluntarily).
