Share your number — a senior GST consultant calls you back within 30 minutes.
Every locality in Chennai has its own commercial rhythm, and Koyambedu is no exception. Koyambedu hosts one of Asia's largest perishables markets, the Koyambedu Wholesale Market Complex, and the CMBT bus terminus, driving trade by vegetable and fruit wholesalers, flower merchants, commission agents and transporters. Fresh produce is largely exempt while packaged and labelled goods are taxable, so mixed supplies, commission income, GTA reverse charge and e-way bills for outstation consignments dominate compliance here. Our practice has shaped its GSTR-1 & GSTR-3B Monthly Filing work around exactly these realities, serving clients in Koyambedu as well as Arumbakkam and Anna Nagar. Registrations, returns, refunds and notice replies are handled by one accountable team, with fees fixed in writing before work begins and every filing reconciled against portal data before it is submitted.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
We tell you when the composition scheme stops making sense, when QRMP suits your cash flow, and when a supplier's non-compliance is quietly costing you credit. Filing is the minimum; helping you make better GST decisions is the actual job.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in Koyambedu would otherwise read about after it lapsed reaches our clients in time.
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 Koyambedu regularly visit us for registrations, notice discussions and annual return reviews.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
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.
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.
Continuous filing protects you from the suspension and cancellation proceedings that hit chronic non-filers, so your registration, e-way bill access and ability to issue tax invoices are never suddenly cut off.
When a query or verification comes, you respond through a professional who deals with the department regularly, in the department's own language and format, instead of facing an officer's letter alone.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

23rd GST Council Meeting, Guwahati — 10 November 2017 (PIB Release ID 1509013) · 2017-11-10
The Council decided that all taxpayers would file GSTR-3B with payment of tax by the 20th of the succeeding month until March 2018, and that for GSTR-1 taxpayers would be divided by turnover. Those with annual aggregate turnover up to Rs 1.5 crore would file GSTR-1 quarterly, and those above that figure monthly, with a detailed table of due dates. Filing of GSTR-1 was to continue without requiring GSTR-2 and GSTR-3 for the previous period.
How we apply it: The turnover-based split between monthly and quarterly GSTR-1 that still determines a Chennai business's filing calendar was created here.
Circular No. 99/18/2019-GST dated 23 April 2019 · 2019-04-23
Following Removal of Difficulty Order No. 05/2019-Central Tax, CBIC clarified that a person whose registration was cancelled on or before 31 March 2019 for non-filing of returns could apply for revocation up to 22 July 2019. Where cancellation took effect from the order date, all returns up to that date had to be filed first. Where it was cancelled retrospectively, returns for the whole period from the effective date of cancellation had to be furnished within thirty days of the revocation order.
How we apply it: This was the first revocation amnesty and set the pattern of every later one, so a Chennai business with a dormant cancelled GSTIN should watch for such windows.
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.
