GST Return Filing
End-to-end monthly and quarterly GST return filing — GSTR-1 and GSTR-3B prepared, reconciled and filed with expert review, so your input tax credit stays intact and you avoid late fees.
Quick answer
GST return filing is the periodic reporting every active GSTIN owes, trading or not. Regular taxpayers file GSTR-1 (outward supplies) and GSTR-3B (summary and tax payment) each period; turnover up to ₹5 crore may file quarterly under QRMP while still paying monthly. We prepare both from your data, reconcile against GSTR-2B, have a qualified professional review the position, and file before the due date.

Overview
What is GST Return Filing?
GST return filing is the periodic reporting of your sales, purchases, tax collected and tax paid to the GST system. Most regular taxpayers file two returns each tax period — GSTR-1 (a statement of outward supplies under section 37, filed in the form prescribed by Rule 59) and GSTR-3B (the summary return under section 39, where the net tax is computed and paid). We handle them as one job, and separately as GSTR-1 filing and GSTR-3B filing where you only need one.
Returns must be filed even when there is no business activity (a 'nil' return). The system links your returns to your customers' input tax credit, which is why accuracy and timeliness directly affect your buyers and your own credit. Section 39(10) now blocks a GSTR-3B for a period where that period's GSTR-1 has not been furnished, and section 37(4) blocks a GSTR-1 where a previous period's is outstanding — so one missed month blocks every month after it.
Two deadlines sit behind the monthly ones and are easy to miss. Input tax credit on an invoice cannot be taken after 30 November following the end of the financial year or the filing of the annual return, whichever is earlier (section 16(4)). And sections 37(5), 39(11) and 44(2), in force since 1 October 2023, bar filing at all three years after the due date — after which there is no return left to file. If you are carrying a backlog, that is the clock that matters. The full cycle is explained in our GST return filing guide.
MyFinancialAdvisory prepares your returns from your sales and purchase data, reconciles them against the auto-drafted GSTR-2B, has a qualified professional review the position, and files on the government portal before the due date — with everything tracked in your portal.

Benefits
Why it's worth doing right
Protect your input tax credit
Timely, reconciled returns keep your ITC and your customers' ITC intact, avoiding blocked credit and awkward conversations. See how input tax credit actually works for the eligibility conditions we check against.
Avoid late fees and interest
We file before the due date, so you don't pay the ₹50/day late fee (₹20/day for nil) under section 47 or the 18% annual interest under section 50 on tax paid late. The fee is capped; the interest is not — work out your own exposure with the GST late fee calculator.
Stay notice-free
Consistent, matched filings reduce the chance of GSTR-1 vs 3B mismatch notices and ITC scrutiny. If one has already arrived, that is a GST notice reply with a deadline on it.
Clean books
Monthly reconciliation keeps your sales, purchases and tax ledgers accurate and audit-ready — and makes the annual return a compilation rather than an investigation.

A clear path from start to filed
Official filing
How the GST Portal (gst.gov.in) flow works
GST returns are filed on the official GST portal. GSTR-1 reports your outward supplies and feeds your customers' GSTR-2B. GSTR-3B is the summary return where the net tax is calculated and paid using the electronic cash and credit ledgers.
The due dates come from the rules, not from custom. Monthly GSTR-1 is due on the 11th — section 37(1) says the 10th, and Notification 83/2020-Central Tax extends it to the 11th, and to the 13th for quarterly filers. Monthly GSTR-3B is due on the 20th under Rule 61(1)(i), uniformly, with no State variation; the 22nd and 24th dates apply only to quarterly QRMP filers under Rule 61(1)(ii). Under QRMP you still pay monthly, in FORM GST PMT-06 by the 25th, for the first two months of each quarter.
A worked example of what lateness costs, so the numbers are not abstract. Take a business with ₹2.4 crore of aggregate turnover in the preceding year that files one GSTR-3B 120 days late with ₹1,80,000 of net tax. The late fee is 120 × ₹50 = ₹6,000, capped at ₹5,000 for that turnover slab. Interest under section 50(1) at 18% for 120 days on ₹1,80,000 is about ₹10,652, and it is not capped. Total: roughly ₹15,652, of which the uncapped interest is more than twice the 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 returns and file them through the proper GST portal workflow. We do not claim any private 'direct API' filing or any arrangement that bypasses the official portal — filing follows the government's own systems and your authenticated access.

- 2Reconcile inward supplies with GSTR-2B

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 all of them are the combined CGST + SGST figure, which is what actually appears on your challan. Rates and caps were checked against the operative notifications on 19 August 2026.

Avoid delays
Common mistakes & reasons for rejection
Common mistakes
- Filing GSTR-3B but forgetting GSTR-1 (or vice versa), creating mismatches
- Claiming ITC not reflected in GSTR-2B, inviting scrutiny
- Ignoring nil periods — a nil return is still mandatory
- Reporting B2B invoices as B2C, breaking the customer's credit
- Missing the QRMP payment in months 1 and 2 of a quarter
Why filings get rejected or delayed
- Tax not paid — GSTR-3B cannot be filed until the liability is settled
- Previous period's return not filed (returns must be sequential)
- Invalid or cancelled GSTIN on B2B invoices
- Portal validation errors from mismatched HSN or place-of-supply data
Risks
Penalties & risks of getting it wrong
Late filing
₹50/day (₹20/day for nil) under section 47, capped per return by turnover slab, plus 18% annual interest under section 50 on tax paid late — which is not capped. Both are payable together.
One missed period blocks the rest
Section 37(4) and section 39(10) prevent filing a period while an earlier one is outstanding, so a single skipped month compounds into a backlog that must be cleared in sequence.
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. See GST notice reply.
Suspension of the GSTIN
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
Section 29(2)(c) with Rule 21 allows cancellation after six months of non-filing (two tax periods for a quarterly filer). Restoring it is a GST revocation application, and blocked e-way bills usually bite first.
The three-year bar
Sections 37(5), 39(11) and 44(2), in force from 1 October 2023, bar furnishing a return three years after its due date. Past that point the period cannot be regularised at all — this is the one deadline with no late fee attached, because there is nothing left to file.

FAQs
GST Return Filing — frequently asked questions
Which GST returns does a regular taxpayer file?
Most regular taxpayers file GSTR-1 (outward supplies) and GSTR-3B (summary and tax payment) each tax period — monthly, or quarterly under the QRMP scheme. Annual return GSTR-9 applies above the turnover threshold.
What are the GST return due dates?
Monthly GSTR-1 is due on the 11th (section 37(1) says the 10th; Notification 83/2020-Central Tax extends it to the 11th) and monthly GSTR-3B on the 20th under Rule 61(1)(i) — uniformly, with no State variation. QRMP filers file GSTR-1 by the 13th after the quarter and GSTR-3B by the 22nd or 24th depending on the State of their principal place of business, under the Table in Rule 61(1)(ii), and pay monthly in PMT-06 by the 25th. Dates are routinely extended by notification, so we confirm the current calendar for your GSTIN each period.
Is GSTR-3B staggered by state like GSTR-1?
No, and this is a common mix-up. The 22nd and 24th dates apply only to quarterly QRMP filers, split by State group under Rule 61(1)(ii). If you file monthly, your GSTR-3B date is the 20th wherever you are. 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 periods.
What is GSTR-1A and when can I use it?
The proviso to Rule 59(1) lets you amend or add details already furnished in GSTR-1 for a period — at your option, in FORM GSTR-1A — but only after filing GSTR-1 and before filing GSTR-3B for that same period. It is the cleanest way to fix a wrong customer GSTIN or a missed B2B invoice before the error reaches your buyer's GSTR-2B. Once GSTR-3B is filed for the period, the correction moves to the amendment tables of a later GSTR-1.
Under QRMP, will my B2B customers wait a quarter for their credit?
Only if you do not use the invoice furnishing facility. Rule 59(2) lets a quarterly filer report B2B outward supplies for the first and second months of a quarter, up to a cumulative ₹50 lakh in each month, using the IFF from the 1st to the 13th of the following month — and Rule 59(3) means those invoices are not repeated in the quarterly GSTR-1. If your customers care about the timing of their credit, we use the IFF; if you sell mostly B2C, it is unnecessary.
Can I still file a return that is several years old?
Generally no. Sections 37(5), 39(11) and 44(2) bar furnishing outward-supply details, a return, or an annual return after three years from the due date, commenced by Notification 28/2023-Central Tax from 1 October 2023. Each carries a proviso allowing the Government to permit late filing by notification, but that is not something to plan on. If you have periods approaching three years old, tell us at the outset — those come first.
Do I have to file if there were no sales?
Yes. A nil return is still mandatory for an active GSTIN. Skipping it blocks the next period's filing and attracts late fees.
What is the late fee for GST returns?
₹50 per day combined CGST and SGST for a normal return, ₹20 per day for a nil return, under section 47 as reduced by notification. The cap on the total fee for that return is ₹500 for a nil return at any turnover, ₹2,000 where aggregate turnover in the preceding year was up to ₹1.5 crore, ₹5,000 above ₹1.5 crore and up to ₹5 crore, and ₹10,000 above ₹5 crore. On top of that sits interest at 18% per annum under section 50 on tax paid late, which is not capped. These are statutory government amounts, not our charge — the GST late fee calculator works out yours.
What is GSTR-2B and why does reconciliation matter?
GSTR-2B is an auto-drafted statement of the input tax credit available to you based on your suppliers' filings. We reconcile your purchases against it so you only claim eligible ITC and chase suppliers for anything missing.
Can I claim input tax credit not showing in GSTR-2B?
Generally, ITC should match GSTR-2B. Claiming credit not reflected there is risky and a common trigger for notices. We flag mismatches and help you resolve them with the vendor.
What is the QRMP scheme?
Quarterly Return Monthly Payment, notified by Notification 84/2020-Central Tax for registered persons with aggregate turnover up to ₹5 crore in the preceding financial year who opt in under Rule 61A. You file GSTR-1 and GSTR-3B quarterly but still pay tax every month in FORM GST PMT-06 by the 25th for the first two months of the quarter. Be clear about what it saves: it halves the filing workload and changes nothing about how often money leaves the business. The option window under Rule 61A(1) runs from the first day of the second month of the preceding quarter to the last day of the first month of the quarter — miss it and you carry your current cadence another quarter. We manage both the monthly payments and the quarterly returns.
What happens if my turnover crosses ₹5 crore while I am on QRMP?
You move to monthly filing, and it is not optional. Paragraph 2 of Notification 84/2020-Central Tax makes you ineligible for quarterly filing from the first month of the quarter succeeding the one in which turnover crossed ₹5 crore, and Rule 61A(2) independently requires the move from the first month of the quarter succeeding the one in which turnover exceeded ₹5 crore in the current financial year. We track the threshold so the switch is planned rather than discovered.
Will you remind me about due dates?
Yes. Your portal tracks every GSTIN's calendar and we remind you well before each due date, so nothing is missed.
Can you file returns for multiple GSTINs or states?
Yes. We handle multi-GSTIN and multi-state filing; pricing is quoted on combined volume under the Business plan.
What happens if I've missed several months?
We bring you back into compliance by filing the pending periods in sequence — sections 37(4) and 39(10) leave no other order — computing the late fee and interest for each, and then keeping you current. Three things we check first: whether any period is close to the three-year bar in sections 37(5) and 39(11), whether the GSTIN has been suspended under Rule 21A (in which case you may not make taxable supplies until it is resolved), and whether a GSTR-3A or cancellation show-cause is already running against you, because those carry their own deadlines and are handled as a GST notice reply.
Is GST filing done directly through a government API?
No. We prepare and review your returns and file them through the official GST portal workflow with your authenticated access. We don't claim any private API or any route that bypasses the government's systems.
Do you handle e-invoicing and e-way bills too?
Where they apply to you, our reviewers check e-invoice and e-way bill data as part of the return process, and we offer dedicated support for both.
Can I switch to you mid-year?
Yes. Share your past filed returns and current data; we'll reconcile the opening position and take over seamlessly.
What do I actually receive each month?
Filed GSTR-1 and GSTR-3B with ARNs, a GSTR-2B reconciliation, the tax payment challan record, and a clean monthly entry in your portal.
Are government late fees included in your fee?
No. Our fee is purely the professional fee. Any statutory late fee or interest is computed transparently and paid by you directly to the government.
How do I get started?
Tell us your GSTIN and monthly volume, share your data, and we'll set up your filing calendar and file the current period before its due date.
