Frequently Asked Questions

Is interest charged on a late GSTR-1?

No — GSTR-1 attracts only the late fee. Interest at 18% p.a. applies to GSTR-3B, on the tax paid late through the cash ledger.

What if I have several pending returns?

Late fee accrues per return, so dues compound quickly across months. We reconcile the ledger, compute the exact dues and bring filings current — often the fee shown on the portal can be reduced where amnesty schemes apply.

Can a late fee be waived?

Only through government-notified waivers or amnesty schemes announced from time to time; there is no general discretion to waive it. We track such notifications — see our compliance calendar.
