GSTR-3B Filing

Reliable GSTR-3B filing — the monthly summary return where your net GST is computed and paid. We reconcile ITC with GSTR-2B, review the position and file on time so you avoid interest and late fees.

Quick answer

GSTR-3B is the self-assessed summary return under section 39 through which GST is actually paid. Monthly filers are due on the 20th under Rule 61(1)(i) — uniformly, with no State variation. The 22nd and 24th apply only to quarterly QRMP filers. We reconcile your input tax credit against GSTR-2B, compute the net tax, have the position reviewed and file before the due date. See GSTR-1 filing for the return that has to go in first.

Overview

What is GSTR-3B Filing?

GSTR-3B is a self-assessed summary return filed each tax period. It consolidates your outward supplies, eligible input tax credit and the net tax payable — and it's the return through which you actually pay GST.

Before filing, your input tax credit should be reconciled against GSTR-2B (the auto-drafted credit statement under Rule 60(7)). Over-claiming ITC or under-reporting output tax in 3B is a leading cause of notices and interest. Section 16(2) sets five conditions that must all hold before credit can be taken: you hold a tax invoice or debit note; the supplier has furnished those details and they have been communicated to you; you have received the goods or services; the credit has not been restricted in the statement communicated under section 38; and the tax has actually reached the Government. See input tax credit for how we test each one.

The due date is the single most misreported fact about this return. Rule 61(1)(i) fixes monthly GSTR-3B at the twentieth day of the following month — everywhere in India, with no State variation. The 22nd and 24th dates that appear in almost every published calendar come from the Table in Rule 61(1)(ii), which by its own terms applies only to registered persons furnishing a return every quarter under the proviso to section 39(1). The old staggering of monthly GSTR-3B by State lived in the provisos to Rule 61(6) and was limited to the October 2020 to March 2021 tax periods. It is dead law. If you file monthly, your date is the 20th.

Under QRMP the return is quarterly but the money is not. Rule 61(3) requires payment for each of the first two months of a quarter in FORM GST PMT-06 by the twenty-fifth of the succeeding month, and the proviso to section 39(7) offers two ways to fix that amount — actual self-assessment, or the prescribed fixed-sum route. QRMP halves your filing workload and changes nothing about how often cash leaves the business, which is worth being clear about before opting in.

We compute your liability, reconcile ITC, get the position reviewed, guide the tax payment via challan, and file GSTR-3B on time. Where the whole cycle is in scope, that is GST return filing; where returns have already fallen behind, section 39(10) means they have to be cleared in sequence.

Official filing

How the GST Portal (gst.gov.in) flow works

GSTR-3B is filed on the GST portal. Net tax is settled from your electronic credit ledger (ITC) and electronic cash ledger (deposits via challan). A return cannot be filed until any tax payable is paid.

Two provisions decide the order you can file in. Section 39(10) bars furnishing a return for a tax period if the return for any previous period has not been furnished, or if the details of outward supplies under section 37(1) for that same period have not been furnished. So a period's own GSTR-1 gates its GSTR-3B, and an old missed month gates everything after it. Section 39(11), commenced by Notification 28/2023-Central Tax from 1 October 2023, then bars furnishing the return at all three years after its due date — after which the period cannot be regularised.

A worked example, because the two charges behave very differently. Take a business with ₹2.4 crore of aggregate turnover in the preceding financial year that files one GSTR-3B 120 days late with ₹1,80,000 of net tax payable. The late fee is 120 × ₹50 = ₹6,000 on the face of it, capped at ₹5,000 for that turnover slab under Notification 19/2021-Central Tax. Interest under section 50(1) at the notified 18% per annum on ₹1,80,000 for 120 days is roughly ₹10,652 — and interest has no cap at all. Total exposure about ₹15,652, of which the uncapped interest is more than twice the capped fee. Had the same period been nil, the whole exposure would have been ₹500. Figures are illustrative; the GST late fee calculator computes your own.

We prepare and review your 3B and file it through the official portal workflow with your authenticated access. We make no claim of private API filing or any route that bypasses the government's systems.

Government and professional charges are shown separately on purpose. Our professional fee is the only amount that comes to us. Every late fee and interest amount above is a statutory sum paid directly to the government, computed transparently and never marked up — and each is the combined CGST + SGST figure that actually appears on your challan. The one number to watch is the interest: the fee is capped and the interest is not, so on a large liability the interest overtakes the fee within weeks. Rates and caps were checked against the operative notifications on 20 August 2026.

After this filing

What you need to stay compliant next

The credit ledger carries forward

Unutilised input tax credit sits in your electronic credit ledger and carries to the next period. We reconcile the closing balance each month so it does not quietly drift from your books.

Reversals under Rule 37

Where a supplier has not been paid within 180 days of the invoice, Rule 37(1) requires a proportionate reversal with interest in the GSTR-3B for the period immediately following those 180 days — and Rule 37(2) allows re-availment once you pay. We track the ageing rather than discovering it at year end.

Annual reconciliation

The year's GSTR-3B figures have to agree with your books and with GSTR-1 when the annual return is prepared. Monthly closes make that a compilation rather than an investigation — handled under our GST Annual Return service.

Avoid delays

Common mistakes & reasons for rejection

Common mistakes

  • Claiming ITC beyond GSTR-2B
  • Forgetting reverse-charge liability
  • GSTR-3B totals not matching GSTR-1
  • Filing late because tax wasn't arranged in time
  • Carrying forward wrong ledger balances

Why filings get rejected or delayed

  • Tax not paid (3B can't be filed with unpaid liability)
  • Prior period 3B not filed — section 39(10) bars filing out of sequence
  • That same period's GSTR-1 not filed — also section 39(10)
  • Ledger/computation validation errors
  • Period already more than three years past its due date, so section 39(11) bars it entirely

Risks

Penalties & risks of getting it wrong

Late filing

₹50 per day combined CGST and SGST under section 47, ₹20 per day where the total central tax payable in the return is nil, capped per return at ₹500 (nil), ₹2,000 (turnover up to ₹1.5 crore), ₹5,000 (₹1.5 crore to ₹5 crore) and ₹10,000 above that under Notification 19/2021-Central Tax and, in the top slab, section 47(1) itself.

Interest is the uncapped half

Section 50(1) charges 18% per annum, notified by Notification 13/2017-Central Tax, on tax paid after the due date. It runs alongside the late fee, not instead of it, and unlike the fee it has no maximum. On a large liability the interest passes the capped fee within a few weeks — the GST late fee calculator shows the crossover for your own numbers.

One missed period blocks the rest

Section 39(10) bars a return for a period where the return for any previous period, or that period's own GSTR-1, is outstanding. A single skipped month therefore compounds into a backlog that must be cleared oldest-first — see GSTR-1 filing.

Notice to a return defaulter

Section 46 requires a notice — FORM GSTR-3A under Rule 68 — giving fifteen days to furnish the return. Filing usually closes it; ignoring it does not, and it escalates to a demand. See GST notice reply.

Suspension, then cancellation

Rule 21A(2A) allows suspension where returns show significant differences or anomalies, with FORM GST REG-31 and thirty days to explain, and Rule 21A(3) bars you from making any taxable supply while suspended. Persistent non-filing then allows cancellation under section 29(2)(c) with Rule 21 after six months (two tax periods for a quarterly filer), which becomes a GST revocation problem.

The three-year bar

Section 39(11), in force from 1 October 2023, bars furnishing a return three years after its due date. Past that point there is no late fee, because there is nothing left to file — and the input tax credit for the period, already closed by section 16(4), is long gone.

FAQs

GSTR-3B Filing — frequently asked questions

What is GSTR-3B?

A monthly (or quarterly under QRMP) self-assessed summary return that consolidates your supplies and ITC and through which you pay your net GST.

When is GSTR-3B due?

Monthly filers: the 20th of the month following the tax period, under Rule 61(1)(i) — uniformly across India, with no State variation. Quarterly QRMP filers: the 22nd or 24th of the month following the quarter, split by the State or Union territory of the principal place of business under the Table in Rule 61(1)(ii), and separately a monthly payment in FORM GST PMT-06 by the 25th for the first two months of each quarter under Rule 61(3). Dates are extended by notification from time to time, so we confirm the live calendar for your GSTIN each period.

Is monthly GSTR-3B staggered by state?

No, and this is the most common mix-up in published GST calendars. The 22nd and 24th apply only to quarterly QRMP filers, split by State group under Rule 61(1)(ii). If you file monthly, your date is the 20th wherever your business sits. The old staggering of monthly GSTR-3B by State lived in the provisos to Rule 61(6) and applied only to the October 2020 to March 2021 tax periods. It has not been law for over five years, but it is still widely republished.

Can I file GSTR-3B without paying tax?

No. Any net tax payable must be paid via challan before the return can be filed.

How is input tax credit handled in 3B?

Eligible ITC reduces your tax payable. We reconcile your purchases with GSTR-2B so the credit you claim is correct and defensible.

What if my GSTR-3B doesn't match GSTR-1?

Mismatches between 1 and 3B are a top reason for GST notices. We keep them consistent and reconcile any differences before filing.

What is reverse charge in 3B?

For certain supplies, the recipient pays GST instead of the supplier. We identify reverse-charge liability and include it correctly.

Is there interest if I pay late?

Yes — 18% per annum under section 50(1), at the rate notified by Notification 13/2017-Central Tax, on tax paid after the due date. It is separate from the section 47 late fee and payable cumulatively with it. The important difference: the late fee is capped per return by turnover slab, and the interest is not capped at all. On a meaningful liability the interest overtakes the capped fee within weeks, which is why paying the tax early is worth more than filing early even when you cannot do both.

Can ITC be claimed in a later month?

Yes, within the outer limit in section 16(4): credit on an invoice or debit note cannot be taken after the thirtieth day of November following the end of the financial year to which it pertains, or the furnishing of the relevant annual return, whichever is earlier. So a March invoice has until roughly 30 November of the same calendar year — unless you file GSTR-9 before that, in which case the window shuts on the earlier date. We track eligible credit and claim it in the correct period rather than letting it drift toward the cut-off.

Do QRMP taxpayers file 3B monthly?

No — the return is quarterly, but the payment is monthly. Rule 61(3) requires payment for each of the first two months of the quarter in FORM GST PMT-06 by the twenty-fifth of the following month, and the proviso to section 39(7) offers two ways to fix that amount: actual self-assessment, or the prescribed fixed-sum route. So QRMP halves the number of returns and changes nothing about how often cash leaves the business. We manage both legs.

What makes a GSTR-3B nil for the lower late fee?

The test is that the total central tax payable in the return is nil — not that you made no sales. That matters because it differs from GSTR-1, where the nil test is no outward supplies in the period. A month where you invoiced customers but offset the entire liability with input tax credit is nil for GSTR-3B and not nil for GSTR-1: same month, two different late-fee slabs, and two different caps.

What do I receive after filing?

The filed GSTR-3B with ARN, the ITC reconciliation, a tax computation summary and the challan record — all in your portal.

Is filing done via a government API?

No. We file through the official GST portal with your authenticated access; we never claim a private API route.

Can you fix several months of pending 3B?

Yes. We file the pending periods in order, compute the late fees and interest, and bring you current.
