GSTR-3B Filing Process

What Is GSTR-3B & Why It Matters

GSTR-3B is a self-declared summary return that every regular GST-registered taxpayer must file, reporting total outward supplies, eligible Input Tax Credit, and the net tax liability payable for the period.

Unlike GSTR-1, GSTR-3B is where actual tax payment happens — it is now largely auto-populated from GSTR-1 and GSTR-2B data, but still needs careful review before submission. Missing the due date attracts late fees, interest, and can even block subsequent return filing and e-way bill generation.

TrustMark IP Consultants manages the complete journey — liability computation, ITC reconciliation with GSTR-2B, challan generation, and timely GST portal filing — so your tax payments and compliance stay on track every period.

Have Questions?

Frequently Asked Questions

GSTR-1 reports invoice-level outward supply details, while GSTR-3B is a summary return where the actual tax liability is computed and paid, based largely on data auto-populated from GSTR-1 and GSTR-2B.

Monthly filers must file by the 20th of the following month, while QRMP scheme taxpayers file quarterly, with due dates of the 22nd or 24th depending on their registered state.

Yes, a Nil GSTR-3B must be filed for the period even with no sales, purchases, or tax liability, to remain compliant and avoid late fees.

No, GSTR-3B cannot be revised once filed; any correction must be made through adjustments in a subsequent period's return.

Late filing attracts a late fee for each day of delay along with interest on the unpaid tax amount, and can also block filing of subsequent returns and generation of e-way bills.

Eligible ITC is largely auto-populated in GSTR-3B from your GSTR-2B statement, and should be reconciled with your purchase records before the return is filed to ensure accuracy.
