Sithalapakkam, between Medavakkam and Perumbakkam, has grown along the Medavakkam - Mambakkam - Sembakkam Road, Ottiambakkam Road and Nookampalayam Road into a belt of plotted layouts, apartment promoters, steel and hardware depots, schools and supermarkets around Skylab Avenue and TNHB Road. Layout promoters here confuse the sale of plots, which is outside GST, with taxable development, amenity and maintenance charges collected from buyers. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Sithalapakkam for years, along with clients from Medavakkam and Perumbakkam. The engagement is simple: one point of contact, a clear fee, documents over WhatsApp or in person at our Chennai office, and senior review before anything is submitted on the portal. What you get in return is clean filings, archived records and far fewer reasons for the department to write to you.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Sithalapakkam compete with each other; complete confidentiality is a condition of our work.
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.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Sithalapakkam never writes back to you as a demand years later.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
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.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
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.
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.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| 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. |
| 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. |
| 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. |
| 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. |
Sowmiya Nagar 1st Main Road is a residential street in Sithalapakkam, about 2.1 km north-east of the centre of Sithalapakkam.

Notification No. 66/2017-Central Tax dated 15.11.2017 · 2017-11-15
This notification exempted all registered persons other than those paying tax under the composition levy from paying GST at the time of receipt of an advance towards a supply of goods. Instead, tax is payable at the time of issue of the invoice, or when the invoice ought to have been issued, under section 12(2)(a). The earlier partial relief limited to suppliers with turnover up to Rs 1.5 crore was superseded and extended to everyone.
Practical effect: A Chennai manufacturer or trader taking booking advances on goods orders pays GST only on invoicing, though advances for services continue to attract tax on receipt.
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.
42nd GST Council Meeting (video conferencing) — 5 October 2020 · 2020-10-05
The Council approved what became the Quarterly Return Monthly Payment scheme. Registered persons with aggregate annual turnover up to Rs 5 crore were allowed to furnish GSTR-3B on a quarterly basis from 1 January 2021, while paying tax monthly through a challan. The due date for the quarterly GSTR-1 was fixed at the 13th of the month following the quarter, and an invoice furnishing facility was provided so that recipients could still see credit monthly. This remains the default compliance route for most small businesses.
What to do about it: A Chennai business under Rs 5 crore can file GSTR-3B four times a year instead of twelve, but must still deposit tax every month, and missing that monthly challan attracts interest.
