The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Chetpet permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.

Chetpet pairs premium healthcare with corporate offices: specialty hospitals and clinics cluster around Spur Tank Road while cafes, boutiques and professional firms occupy Harrington Road and McNichols Road. Landlords letting commercial space and clinics with mixed exempt and taxable income dominate the compliance workload, particularly GST on commercial rentals and input tax credit reversal under Rules 42 and 43. Against that backdrop, GSTR-1 & GSTR-3B Monthly Filing in Chetpet demands more than data entry — it needs reconciliation before filing, correct classification and awareness of what local officers examine. Our Chennai team provides exactly that to clients in Chetpet, Kilpauk and Egmore, with same-day responses on working days and WhatsApp updates at every stage. Most routine engagements complete within one to two working days once documents are in hand.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Chetpet. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
Every acknowledgement, challan, computation sheet and filed return is saved and shared with you in an organised folder. When a bank, buyer or GST officer asks for a document from two years ago, it reaches you the same day without any scrambling.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
At month end we remind you and collect sales invoices, purchase bills and credit notes in whatever format you maintain, including Excel, Tally exports or scanned copies.
We prepare invoice-wise outward supply details, validate GSTINs of your B2B customers, summarise B2C supplies and file GSTR-1 on the portal before the 11th.
We download your auto-drafted GSTR-2B, match it against purchase records, and claim only eligible input tax credit so that mismatches do not trigger scrutiny notices later.
We compute net tax payable after ITC set-off, share the working with you for approval, and generate the payment challan for any cash liability.
After your confirmation and tax payment, we file GSTR-3B before the 20th and send you both filed acknowledgements along with a one-page summary of the month.
Send these on WhatsApp (+91 - 9600 606 444) and we take it forward the same day.

Practical outcomes our clients measure us by.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| Due-date tracking | A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around. | Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| Risk of notices | GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices. | Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice. |
| Portal credentials and data | Logins handled by a small engaged team under strict confidentiality, with credentials stored securely and never passed onward. | Passwords circulating on chats with freelancers and part-timers, and no accountability for who has accessed your business data. |
| Supplier defaults | Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit. | Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult. |

The same consultant covers the streets immediately around it — 5th Avenue (about 50 m); 7th Avenue (about 50 m); 4th Avenue (about 100 m); 2nd Avenue (about 150 m) — so a site visit on 6th Avenue can usually be combined with other work in Chetpet on the same trip. For GST purposes an address on 6th Avenue falls under the Chennai North CGST Commissionerate, and the Chetpet pincode is 600031.

Eicher Motors Ltd v. Superintendent of GST and Central Excise — Madras High Court, 2024 · 2024-01-23
Eicher Motors had deposited tax amounts into its electronic cash ledger before the due dates but filed GSTR-3B belatedly owing to transitional credit issues, and the department demanded interest under Section 50. The Madras High Court held that once the amount is credited to the Government via the electronic cash ledger by the due date, the tax liability stands discharged to that extent, and no interest is leviable merely because the return was filed late. This reasoning has since been followed by other High Courts.
What to do about it: If cash was parked in your electronic cash ledger before the due date, contest any interest demand for delayed GSTR-3B filing on that amount.
GSTN Advisory, November 2024 — 30-day IRP reporting limit for AATO Rs 10 crore and above · 2024-11
GSTN advised that from 1 April 2025, taxpayers with annual aggregate turnover of Rs 10 crore and above cannot report e-invoices on the Invoice Registration Portals beyond 30 days from the document date. The restriction, earlier applicable only to very large taxpayers of Rs 100 crore and above, covers invoices, credit notes and debit notes. The IRP validation simply rejects documents older than 30 days, so late reporting becomes impossible.
Why this matters: Automate same-day or same-week IRN generation, because an invoice missed beyond 30 days cannot be e-invoiced at all and endangers the buyer's ITC.
Notification No. 19/2021-Central Tax · 2021-06-01
For the tax periods July 2017 to April 2021 the late fee on GSTR-3B was capped at Rs 1,000 per return, being Rs 500 each under the central and State laws, and at Rs 500 per return where the return was a nil return. The concession applied to returns furnished between 1 June 2021 and 31 August 2021. The same notification rationalised the late fee prospectively from June 2021, capping it at Rs 500 for nil returns, Rs 2,000 where turnover is up to Rs 1.5 crore, Rs 5,000 where turnover is between Rs 1.5 crore and Rs 5 crore, and leaving the normal Rs 10,000 ceiling for turnover above Rs 5 crore.
How we apply it: This scheme let a Chennai business clear four years of pending returns for a few thousand rupees, and it also fixed the low late fee ceilings that small taxpayers still enjoy today.
