GST Return Filing (GSTR-1 & 3B) (₹499) | Mazco Corporate Services

Why Timely GST Return Filing is Vital

Under GST regulations, every registered business entity must submit periodic returns summarizing outward sales (GSTR-1) and monthly tax liability with input tax credit adjustments (GSTR-3B), irrespective of whether any business transactions occurred during the period.

Failing to file returns by the statutory due dates triggers mandatory daily compounding late fees (up to ₹50/day), 18% per annum statutory interest, and can lead to the freezing of your E-Way Bill portal and automatic GSTIN cancellation under Section 29.

Key Statutory Benefits & Business Advantages

Holding a verified, compliant registration delivers substantial commercial and legal protections:

100% ITC Claim Optimization

Match your purchase ledger with GSTR-2B to ensure not a single rupee of eligible input tax credit is lost or forfeited.

Avoid Daily Late Fee Penalties

Strict adherence to statutory monthly deadlines (11th for GSTR-1, 20th for GSTR-3B) prevents accumulated penalties.

Audit-Ready Reconciliations

Systematic matching of sales, e-way bills, and purchase registers to keep your books prepared for GST audits.

Maintain High Vendor Rating

Your buyers can only claim ITC if you file GSTR-1 on time. Timely filing protects your commercial credibility.

Uninterrupted E-Way Bill Access

Non-filing for two consecutive periods blocks E-Way Bill generation, halting goods transport and outward shipment delivery.

Dedicated Tax Accountant

A qualified compliance manager handles your filings, verifies invoices, and resolves vendor mismatch queries.

Key GST Return Types and Statutory Due Dates

Understanding the regular return filing framework under GSTN:

Return Form	Statutory Purpose	Filing Frequency & Due Date
GSTR-1	Details of Outward Supplies (Sales invoices)	Monthly by 11th / Quarterly by 13th (QRMP)
GSTR-2B	Auto-Drafted Input Tax Credit Statement	Generated by portal on 14th of each month
GSTR-3B	Summary Return & Net Tax Settlement	Monthly by 20th of succeeding month
CMP-08	Quarterly Statement for Composition Dealers	Quarterly by 18th of succeeding month
GSTR-9 & 9C	Annual GST Return & Reconciliation Statement	Annually by 31st December

Compliance Note: Nil Return Filing: Even if your business had zero commercial activity in a month, filing a Nil GSTR-1 and GSTR-3B is mandatory to prevent statutory penalties.

Frequently Asked Questions

Late filing attracts a statutory late fee of ₹50 per day of delay (₹20 per day for Nil returns) subject to a maximum cap. Additionally, interest at 18% per annum is payable on net cash tax liability.

GSTR-1 is an informational return where you report itemized sales invoices and debtor details. GSTR-3B is a summary return where you declare total sales, claim input tax credit (ITC), and pay net tax.

Under Section 16(2)(aa) of the CGST Act, you can only claim Input Tax Credit if the vendor has uploaded the invoice in their GSTR-1 and it reflects in your GSTR-2B.

GST returns cannot be revised once filed. However, any omissions or amendments (such as invoice values, GST numbers) can be rectified in the subsequent month's GSTR-1.

Quarterly Return Monthly Payment (QRMP) allows businesses with annual turnover up to ₹5 Crore to file GSTR-1 and GSTR-3B quarterly while paying estimated tax monthly.

You must file a Nil Return. Neglecting to file a Nil return will still trigger ₹20/day daily late fees until the filing is completed.
