End-to-End GST Registration & Filing Services

The GST regime requires continuous vigilance. With automated cross-verification between GSTR-1, GSTR-2B, and GSTR-3B, even minor data mismatches trigger departmental scrutiny notices (ASMT-10) or blockage of Electronic Credit Ledgers under Rule 86A.

At Abinash & Co., we manage your complete GST lifecycle, conducting monthly purchase register audits to maximize eligible Input Tax Credit (ITC) while keeping your business immune from penal interest and late fees.

Frequently Asked Questions (GST)

What is the penalty for filing late GST returns?

Under Section 47 of the CGST Act, late fee is ₹50 per day (₹20 per day for Nil returns) up to a maximum of ₹5,000 per return. Additionally, 18% p.a. penal interest applies under Section 50 on unpaid tax liability.

Why is GSTR-2B Input Tax Credit (ITC) reconciliation essential?

Under Rule 36(4) of CGST Rules, businesses can only claim ITC that appears in their auto-drafted GSTR-2B statement. Claiming unverified ITC triggers automated GST ASMT-10 scrutiny notices and DRC-01 tax demands.

Can a cancelled GST registration be revoked?

Yes. An application for revocation of GST cancellation can be submitted under Section 30 by filing all pending returns and clearing outstanding tax liabilities within prescribed statutory timelines.
