Frequently asked questions
What is the difference between GST late fee and GST interest?
Late fee is a flat penalty for delayed filing — it accrues per day regardless of tax liability (nil returns also attract late fee). Interest at 18% p.a. applies only on unpaid tax liability and is calculated on the amount outstanding for the number of days it remains unpaid.
Is there any waiver or amnesty for old GST late fees?
The government has periodically announced GST amnesty schemes reducing late fees. Most recently, the GST Council reduced maximum late fees and offered waivers for delayed filings before specified dates. Check the GST portal for current amnesty notifications.
What happens if I don't file GSTR-1?
If GSTR-1 is not filed, your buyers cannot claim ITC (Input Tax Credit) on purchases from you. Non-filing also blocks your GSTR-3B filing for the same period, as GSTR-3B auto-populates from GSTR-1 data.
Can a suspended GSTIN file late returns?
Yes — suspended GSTINs can still file pending returns to regularize the registration. Once all pending returns are filed and dues cleared, suspension can be revoked. Cancellation of GSTIN requires filing all returns and paying all dues.

GST interest on unpaid tax
Interest at 18% per annum is charged on the gross tax liability not paid by the due date. For excess ITC claimed or ineligible ITC, the interest rate is 24% p.a. Interest must be paid along with the tax — failure to pay interest makes the taxpayer liable for further proceedings under the GST Act.
