GST<\/a>R-3B is the most frequently filed GST return in India. Every regular GST-registered tax<\/a>payer files it monthly (or quarterly under the QRMP scheme) to declare their output tax liability and claim Input Tax Credit. Getting GSTR-3B right every month is the foundation of GST compliance for any business.<\/p>\n

What is GSTR-3B?<\/h2>\n

GSTR-3B is a monthly self-declaration summary return filed by regular GST taxpayers. It is not a detailed invoice-level return. Instead, it summarises:<\/p>\n

– Total outward taxable supplies and the GST collected.
\n– Inward supplies subject to reverse charge.
\n– Input Tax Credit claimed.
\n– Net tax payable or carried forward.<\/p>\n

Despite being a summary return, GSTR-3B has legal significance. It is the primary document through which GST is paid to the government each month.<\/p>\n

Who Must File GSTR-3B?<\/h2>\n

All GST-registered taxpayers except the following must file GSTR-3B:<\/p>\n

– Input Service Distributors (ISDs), who file GSTR-6.
\n– Non-resident taxable persons, who file GSTR-5.
\n– Composition scheme taxpayers, who file CMP-08 and GSTR-4.
\n– Online Information and Database Access or Retrieval (OIDAR) service providers.<\/p>\n

Due Dates for GSTR-3B<\/h2>\n

The due date depends on the taxpayer’s turnover and filing frequency:<\/p>\n

– **Monthly filers (turnover above Rs. 5 crore):** 20th of the following month.
\n– **QRMP scheme (quarterly filers) in Category 1 states:** 22nd of the month following the quarter.
\n– **QRMP scheme in Category 2 states:** 24th of the month following the quarter.<\/p>\n

QRMP (Quarterly Return Monthly Payment) scheme allows businesses with turnover up to Rs. 5 crores to file GSTR-3B quarterly while paying tax monthly via a challan (PMT-06).<\/p>\n

Key Sections of GSTR-3B<\/h2>\n

**Table 3.1: Outward Supplies**
\nReport total taxable value and tax collected for regular supplies, zero-rated supplies (exports), exempt supplies, and nil-rated supplies.<\/p>\n

**Table 3.2: Inter-State Supplies to Unregistered Persons, Composition Dealers, and UIN Holders**
\nBreak down of inter-state B2C and specific category supplies.<\/p>\n

**Table 4: ITC Available and Eligible**
\nShow all ITC available (from GSTR-2B) and separate eligible ITC from ineligible (blocked credits under Section 17(5)<\/a>).<\/p>\n

**Table 5: Exempt, Nil-Rated, and Non-GST Supplies**
\nSummarise all non-taxable supply values.<\/p>\n

**Table 6: Tax Payable**
\nCompute the net tax after setting off ITC against output liability.<\/p>\n

Payment of Tax Through GSTR-3B<\/h2>\n

Tax is paid before or along with GSTR-3B filing. The payment uses the Electronic Cash Ledger (cash deposited at bank) or the Electronic Credit Ledger (ITC balance). CGST and SGST credits can only be used against CGST and SGST liabilities<\/a> respectively. IGST<\/a> credit can be used for any liability.<\/p>\n

Late Filing and Penalties<\/h2>\n

If GSTR-3B is filed late:<\/p>\n

– Late fee: Rs. 50 per day (Rs. 20 per day for nil returns), subject to a maximum of Rs. 10,000 per return.
\n– Interest: 18% per annum on the unpaid tax from the due date to the actual payment date.<\/p>\n

Interest is also charged at 18% on excess ITC claimed without adequate GSTR-2B support.<\/p>\n

Practical Example<\/h2>\n

XYZ Traders is a monthly filer with turnover above Rs. 5 crores. For October 2024, its output liability is Rs. 4 lakhs and eligible ITC per GSTR-2B is Rs. 2.5 lakhs. Net tax payable = Rs. 1.5 lakhs. XYZ must pay Rs. 1.5 lakhs and file GSTR-3B by November 20, 2024.<\/p>\n

Key Takeaways<\/h2>\n

– GSTR-3B is a monthly summary GST return filed by all regular taxpayers.
\n– Due date: 20th of the following month for monthly filers; 22nd or 24th for quarterly QRMP filers.
\n– ITC claims must be based on GSTR-2B data under Rule 36(4).
\n– Late filing attracts Rs. 50\/day late fee (Rs. 20\/day for nil returns) and 18% interest on unpaid tax.
\n– Tax is paid via the Electronic Cash or Credit Ledger before or at the time of filing.
\n– Composition dealers, ISDs, and NRTPs do not file GSTR-3B.<\/p>\n

Filing GSTR-3B accurately and on time every month is the most basic and critical GST compliance obligation for any regular taxpayer. Errors in GSTR-3B can lead to demand notices, audits, and penalties.<\/p>\n","protected":false},"excerpt":{"rendered":"
