Our consultants provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Nanmangalam starting at Rs.749. Every file is reconciled and senior-reviewed before submission, which is why our clients see far fewer departmental queries than they did while self-filing.
We serve businesses on and around Medavakkam Bus Terminus — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
If you operate in Nanmangalam, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. Nanmangalam, ringed by the Nanmangalam Reserve Forest and its worked-out quarries, hosts blue-metal crushers, M-sand and ready-mix depots, lorry fleets and building-material yards along Dr. Ambedkar Main Road, Vadakkupattu Road and S.I.V.E.T. College Road towards Medavakkam Koot Road. Reverse charge on mining royalty and seigniorage, and e-way bills for short-haul aggregate lorries, are the recurring disputes here. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Nanmangalam and the adjoining Kovilambakkam and Medavakkam localities, maintaining a compliance calendar for every client so due dates are met without last-minute panic, late fees or interest at 18 percent per annum.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from Nanmangalam regularly visit us for registrations, notice discussions and annual return reviews.
When an ADT-01 audit intimation or a personal hearing date arrives, we compile the records, prepare the reconciliations and draft the submissions, and coordinate closely with your authorised representative. You walk into the proceeding prepared, not improvising in front of an officer.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Nanmangalam are comfortable with, and keeps written communication simple and jargon-free.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
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.
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.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
| 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. |
| 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. |
| Annual return preparation | Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year. | Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly. |
| 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. |
| 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. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
What to do about it: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
Entry 12, Notification No. 12/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
As originally notified, Entry 12 exempted renting of a residential dwelling for use as residence, without any condition about who the tenant was. From 1 July 2017 to 17 July 2022 a house or flat let out for residential use carried no GST, whether the tenant was an individual, a firm or a company. The entry was narrowed with effect from 18 July 2022 so that the exemption no longer applies where the tenant is a registered person.
What to do about it: For rent periods up to 17 July 2022 a Chennai landlord had no GST liability on residential letting, which is a useful defence if an old notice questions those years.
Mahadeo Construction Co. v. Union of India — Jharkhand High Court, W.P.(T) No. 3517 of 2019, judgment dated 21 April 2020, reported at [2020] 116 taxmann.com 262 (Jharkhand) · 2020-04-21
The department issued recovery notices for interest under Section 50 without any adjudication, treating the interest as automatically payable. The High Court held that although interest liability under Section 50 is automatic in principle, its computation and quantum are not. Where the taxpayer disputes the liability, the department must first initiate adjudication proceedings under Section 73 or 74 and pass an order before resorting to recovery under Section 79.
What it means for you: A bare recovery letter for interest, without a show cause notice and order, can be challenged if you genuinely dispute the amount.
