GST Return Filing - accurate, every month
Every GSTIN holder has to file returns — monthly, quarterly and annually — whether or not there were any sales. Our CAs reconcile your invoices, match your input tax credit and file on the GST portal well before the due date, so late fees and blocked e-way bills never become your problem.
- GSTR-1 and GSTR-3B prepared and filed on the GST portal
- Monthly filing or QRMP quarterly filing, whichever applies to you
- Input tax credit reconciled against GSTR-2B before filing
- Nil returns filed for months with no sales — still mandatory
- GSTR-9 annual return and year-end reconciliation on the yearly plan
Our expert will connect with you for a detailed consultation.
What is GST Return Filing?
A GST return is the periodic statement every registered taxpayer files on the GST portal, declaring outward supplies, inward supplies, input tax credit claimed and tax paid. It is not a one-time formality — the moment you hold a GSTIN, the filing obligation runs every month or quarter for as long as the registration is active, and it continues even in a month where you made no sales at all.
Most businesses file two returns each period: GSTR-1 for outward supplies and GSTR-3B, a summary return through which tax is actually paid. Businesses with turnover up to ₹5 crore can opt for the QRMP scheme and file both quarterly while paying tax monthly, which is what most small businesses are on. Composition dealers file GSTR-4 annually with quarterly payments in CMP-08, and regular taxpayers close the year with the GSTR-9 annual return.
At LegalFidelity, a dedicated chartered accountant collects your sales and purchase data, reconciles your input tax credit against GSTR-2B, files the returns on the portal and sends you the acknowledgement. If you registered for GST elsewhere and your filings have fallen behind, we take over the GSTIN and bring it current.
Why timely GST return filing matters
Protect your input tax credit
Credit is claimed through GSTR-3B within the statutory window. File late and the credit for those purchases can be lost for good.
Keep your buyers happy
Your invoices only reach a buyer's GSTR-2B once you file GSTR-1. Until then they cannot claim credit — and B2B customers do notice.
Keep e-way bills working
Two consecutive missed returns and the portal blocks e-way bill generation, which means your goods stop moving.
No late fees or interest
Late fees accrue per return per day and interest runs on unpaid tax. Filing on time keeps both at zero.
Never miss a due date
A compliance calendar and reminders before every deadline, with a CA who chases you rather than the other way round.
Stay creditworthy
A clean filing history on the GST portal is what banks, tender committees and large buyers check before they deal with you.

Regular vs QRMP vs Composition
Your filing obligation depends on the scheme you are registered under. Here is what each one actually requires.
| Regular (monthly) | QRMP | Composition | |
|---|---|---|---|
| Turnover limit | Any turnover | Up to ₹5 crore | Up to ₹1.5 crore |
| GSTR-1 | Monthly | Quarterly (optional monthly IFF) | Not applicable |
| GSTR-3B | Monthly | Quarterly | Not applicable |
| Tax payment | Monthly with GSTR-3B | Monthly in PMT-06 | Quarterly in CMP-08 |
| Annual return | GSTR-9 | GSTR-9 | GSTR-4 |
| Input tax credit | Available | Available | Not available |
| Best for | B2B and high-volume sellers | Most small businesses | Small local retailers |
What a missed return actually costs
The late fee is only the visible part. Non-filing quietly blocks your e-way bills and strips your buyers of the credit they were expecting, which is what turns a small delay into a lost customer.
A late fee of ₹50 per day (₹20 per day for a nil return) accrues on every return you miss, and it runs separately on each pending return until it is filed.
Interest at 18% per annum runs on any unpaid tax from the day after the due date until the tax is actually paid.
Miss two consecutive tax periods and the portal stops you generating e-way bills — your goods cannot legally move until you file.
Until you file GSTR-1, your invoices never appear in your buyers' GSTR-2B and they cannot claim input tax credit on what they bought from you.
Zero sales does not mean zero filing. The return is still due, and skipping it accrues late fees exactly the same way.
Frequently asked questions
Most regular taxpayers file two returns per period:
- GSTR-1 — details of outward supplies (your sales).
- GSTR-3B — a summary return through which tax is actually paid.
The year is closed with the GSTR-9 annual return. Composition dealers instead pay quarterly in CMP-08 and file GSTR-4 annually.
Yes. A nil return is still mandatory. This is one of the most expensive misunderstandings in GST — skipping a nil month accrues a late fee of ₹20 per day per return, and two consecutive missed periods will block your e-way bills.
A late fee of ₹50 per day, per return (₹20 per day for a nil return), plus interest at 18% per annum on any unpaid tax. Beyond the money, non-filing blocks e-way bill generation and prevents your buyers from claiming input tax credit on your invoices.
Yes, on the higher tiers. Our GST registration Standard plan includes 3 months of return filing and the Premium plan includes 12 months. This service is for businesses that registered elsewhere, or whose bundled filing period has ended.
