GST Late Fee, Penalty, and Interest 2026 — What You Owe for Missing Deadlines | RushTax Blog

Missing GST filing deadlines is expensive. Late fees, interest, and penalties add up quickly. Here is the complete guide to GST late fees and interest for FY 2026-27, and how to minimise them.

GSTR-1 Late Fee

Condition	Late Fee
Nil return (no outward supplies)	₹20 per day (₹10 CGST + ₹10 SGST)
Return with outward supplies	₹50 per day (₹25 CGST + ₹25 SGST)
Maximum late fee	₹10,000 (₹5,000 CGST + ₹5,000 SGST)

Note: GSTR-1 late fee is waived if GSTR-3B is filed on time. But if GSTR-1 is filed late, the buyer cannot claim ITC on your invoices until you file.

GSTR-3B Late Fee

Condition	Late Fee
Nil return	₹20 per day
Return with tax liability	₹50 per day
Maximum late fee	₹10,000

GSTR-3B Interest on Unpaid Tax

If you file GSTR-3B on time but have unpaid tax (because you claimed excess ITC or underpaid):

Interest rate: 18% per annum
Period: From the due date to the date of payment
Calculated on: Net tax payable (after ITC)

Example:

Tax payable: ₹1,00,000
Filed on time but paid ₹80,000
Shortfall: ₹20,000
Interest (30 days): ₹20,000 × 18% × 30/365 = ₹296

Interest on Excess ITC Claim

If you claim ITC that is later found to be ineligible (not in GSTR-2B, blocked credit, etc.):

Interest rate: 18% per annum
Period: From the date of ITC claim to the date of reversal

GSTR-9 Late Fee

Condition	Late Fee
All taxpayers	₹200 per day (₹100 CGST + ₹100 SGST)
Maximum	0.25% of turnover in the state

GSTR-4 (Composition) Late Fee

Condition	Late Fee
Nil return	₹20 per day
Return with tax	₹50 per day
Maximum	₹2,000

Penalty for Non-Filing

If you do not file GST returns at all (not just late filing):

Penalty: ₹10,000 or the amount of tax evaded, whichever is higher
For each return: Separate penalty applies

Penalty for Fraud and Tax Evasion

Offence	Penalty
Tax evasion (fraud)	100% of tax evaded
Incorrect ITC claim (fraud)	100% of ITC wrongly claimed
Incorrect ITC claim (non-fraud)	10% of tax or ₹10,000, whichever is higher

How to Reduce Late Fees

GST Amnesty Schemes

The GST Council periodically announces amnesty schemes that waive or reduce late fees for past periods. Check the GST portal for current schemes.

Nil Return Late Fee Reduction

For nil returns (no business activity), the late fee is only ₹20/day — much lower than the ₹50/day for returns with transactions.

File Immediately

The longer you delay, the higher the late fee. File as soon as possible to stop the late fee from accumulating.

Frequently Asked Questions

Can late fees be waived?

Late fees can be waived only through GST Council notifications or amnesty schemes. You cannot request a waiver individually.

Is there interest on late fee?

No. Interest applies only on unpaid tax, not on late fees.

What if I cannot pay the full tax — should I still file?

Yes. File the return even if you cannot pay the full tax. Late filing attracts both late fee and interest. Not filing at all attracts additional penalties.

Can I file GSTR-3B without paying tax?

Yes, but interest at 18% per annum will apply on the unpaid amount from the due date.
