The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Tambaram permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Darkas Road (Kishkinta Road) — 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.
Tambaram is the southern suburbs' trading hub: wholesale and retail clusters around Duraisamy Reddy Street and Gandhi Road in West Tambaram, MEPZ-SEZ exporters at Tambaram Sanatorium and institutions like Madras Christian College. Suppliers to MEPZ units must execute zero-rated supplies under LUT with proper endorsements, and wholesalers carry chronic ITC mismatch exposure from multi-supplier purchases. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Tambaram, Chromepet and Selaiyur on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
Every new client receives a review of their recent returns before we file anything — unclaimed credit, GSTR-1 versus GSTR-3B drift, and exposures worth correcting quietly. Businesses in Tambaram often discover in this first review exactly why their previous arrangement was costing them money.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in Tambaram never leave marketplace deductions unclaimed.
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.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
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.
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.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Time cost | Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours. | Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself. |
| Late fees and interest | Filings go in ahead of statutory dates, so the Rs.50-per-day late fee and 18 percent interest never arise. | Late fees accumulate silently every delayed day, and interest on unpaid tax runs at 18 percent per annum. |
| Refund claims | RFD-01 filed with complete statements and annexures, tracked from ARN to bank credit, with any deficiency memo answered promptly. | Incomplete claims bounce back as deficiency memos while the refund sits unclaimed for months and working capital stays blocked. |
| 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. |
| 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. |
Darkas Road (Kishkinta Road) is a secondary arterial road in Tambaram, about 2.8 km west of the centre of Tambaram.

11th GST Council Meeting, New Delhi — 4 March 2017 (PIB Release ID 1483622) · 2017-03-04
The Council approved the draft CGST and IGST Bills as vetted by the Law Ministry, clearing them for introduction in Parliament. The approved design provided for State-wise single registration, a single State-wise return covering intra-State, inter-State and export supplies, registration exemption below Rs 20 lakh turnover (Rs 10 lakh in Special Category States), a composition scheme up to Rs 50 lakh, broad input tax credit entitlement, and cross-utilisation of credit between CGST, SGST, UTGST and IGST in a prescribed order.
What it means for you: The structural features a Chennai business deals with every day, from one GSTIN per State to the credit set-off order, were locked in at this meeting.
GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
Why this matters: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
Circular No. 142/12/2020-GST dated 9 October 2020 · 2020-10-09
As a Covid relief measure, the rule 36(4) credit restriction was not applied separately for each of the tax periods February to August 2020. CBIC clarified that the taxpayer must instead apply the restriction cumulatively for those seven months while filing the GSTR-3B for September 2020, comparing the aggregate credit taken with the aggregate credit reflected in GSTR-2A for that whole span, and reversing any excess in that return.
What to do about it: Any scrutiny of credit for the first Covid year must be tested cumulatively for February to August 2020, not month by month.
