How it is calculated
Worked example
GSTR-3B for a taxpayer with ₹3 crore turnover filed 40 days late: 40 × ₹50 = ₹2,000, below the ₹5,000 cap, so the late fee is ₹2,000 (₹1,000 CGST + ₹1,000 SGST). Interest on unpaid tax is extra.

Frequently asked questions
Does the late fee apply if I have no tax to pay?
Yes — a nil return still must be filed on time. The lower nil-return fee of ₹20 per day (capped at ₹500) applies.
How is the number of days counted?
From the day after the due date up to the date the return is filed. The portal computes this automatically when you file.
Can the late fee be waived?
Only through a government waiver or amnesty notification (these have been issued from time to time). Check the CBIC notifications page for any scheme open to you.
