GST Return Filing (GSTR-1 & GSTR-3B)

Why GST filing never stops — and why that matters

Registration gets you a GSTIN; filing is what keeps it healthy. From the month your registration is active, the law expects a return on schedule — most commonly GSTR-1 and GSTR-3B — whether you had a hundred invoices or none at all. There is no "quiet month" in GST: a month with no sales still needs a Nil return.

This is the part businesses underestimate. The one-time registration is easy to remember; it is the relentless monthly rhythm — collect data, reconcile credit, pay the right tax, file before the date — that quietly eats time and, when missed, money. Our ₹499/month plan exists precisely to carry that rhythm for you so nothing slips.

GSTR-1 and GSTR-3B: what each return actually does

GSTR-1 is your statement of outward supplies — the detail of every sales invoice, credit note and debit note for the period. It is what flows into your buyers’ GSTR-2B and lets them claim input tax credit, so errors here quietly cost your customers and damage relationships.

GSTR-3B is the summary-and-payment return. In it you declare your total outward supplies, claim your eligible input tax credit, and pay the net tax. Think of GSTR-1 as the detailed ledger and GSTR-3B as the summary where money actually changes hands. The two must tell a consistent story; when the department sees GSTR-1 and GSTR-3B disagree, a notice usually follows.

Monthly filing or QRMP? Getting the frequency right

Businesses with turnover above ₹5 crore file monthly. Those up to ₹5 crore can opt for the QRMP scheme — Quarterly Return, Monthly Payment — where GSTR-1 and GSTR-3B are filed once a quarter but tax is still paid every month through a simple challan (PMT-06). QRMP cuts filing frequency without letting your tax dues pile up, and the optional Invoice Furnishing Facility (IFF) lets you still pass on credit to buyers in the first two months of a quarter.

The right choice depends on your turnover, your buyers’ credit needs and your cash flow. We set you up on the frequency that keeps your customers happy and your compliance light, and switch it if your business changes.

The due dates you cannot miss

For monthly filers, GSTR-1 is generally due by the 11th and GSTR-3B by the 20th of the following month. Under QRMP, quarterly GSTR-1 is due around the 13th of the month after the quarter, quarterly GSTR-3B around the 22nd or 24th depending on your state group (Gujarat falls in the 22nd group), with monthly tax paid via PMT-06 by the 25th in the first two months of each quarter.

These dates move occasionally through government notifications, especially around year-end. We track them for you and always work several days ahead, so a portal slowdown on the due date is never your problem.

Input tax credit reconciliation — where the money is won or lost

The single most valuable thing we do each month is reconcile your purchases against your GSTR-2B — the auto-drafted statement of credit your suppliers have actually reported. Claiming exactly what appears there means you capture every rupee of credit you are entitled to, and none that you are not.

This matters both ways. Under-claiming quietly inflates the tax you pay. Over-claiming — for example, on an invoice a supplier never filed — is what triggers demands for reversal with interest. Careful, monthly reconciliation is the difference between GST that costs you the right amount and GST that costs you a notice.

Nil returns are still mandatory

A surprising amount of avoidable late fee comes from one belief: "I had no sales, so I don’t need to file." You do. A Nil return must still be filed by the due date, and skipping it accrues a per-day late fee just the same. We file your Nil returns automatically in quiet months so a slow patch never becomes a bill.

Late fees and interest — the real cost of missing a date

File late and two separate charges can apply. A late fee accrues per day of delay — a lower rate for Nil returns and a higher rate for returns with transactions, subject to a cap. On top of that, interest (generally 18% per annum) runs on any tax you pay after the due date. Individually small, these add up fast across several returns, and persistent non-filing can get your GSTIN suspended, which stops you issuing valid tax invoices at all.

The cheapest late fee is the one you never incur. Our whole model is built around filing early, so you keep that money.

What we do for you every month

Each cycle follows the same disciplined routine so nothing depends on anyone remembering. Ahead of the due date we remind you on WhatsApp and collect your sales and purchase data — or pull it straight from the free billing software if you use it. We reconcile your input tax credit against GSTR-2B, prepare GSTR-1 and GSTR-3B, and confirm the exact net tax payable with you before anything is filed. Then we file within the due dates and send you the filed returns and acknowledgements for your records.

You approve the numbers; we handle the portal, the deadlines and the paperwork.

Switching from another consultant is easy

If your current accountant is slow, unresponsive, or leaves you chasing acknowledgements, moving to us is straightforward and common. We review your recent filings, flag anything pending or mismatched, and take over cleanly from the next return period — no gap, no double filing. You keep your GSTIN and your history; you just stop worrying about it.

How monthly filing feeds your annual return

Every monthly return you file is a building block of your annual return (GSTR-9), and larger taxpayers also file a reconciliation statement (GSTR-9C). When the monthly work is done accurately and reconciled through the year, the annual return is a summary, not a scramble — and full-year mismatches that would otherwise surface as notices simply do not arise. Clean monthly filing is the best protection against a painful year-end.

Free billing software that makes filing effortless

Good filing starts with good records. As an active monthly filing customer you get GST-ready billing software at no extra cost — raise proper tax invoices, track your customers, sales and purchases, and generate GST-ready summaries. Because your data is already organised, each month’s filing is faster, your input tax credit is captured accurately, and there is far less back-and-forth. It is one ecosystem: bill your customers and stay compliant from the same place.
