Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete Composition & CMP-08 for Sithalapakkam businesses from Rs.499, matching every figure against portal data before anything reaches the department.
Share your number — a senior GST consultant calls you back within 30 minutes.
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. Years of working in and around Sithalapakkam have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our Composition & CMP-08 is built to close precisely those gaps, and the same team supports businesses in Medavakkam and Perumbakkam, each with one point of contact and a compliance calendar maintained on their behalf.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
E-invoicing is mandatory once turnover crosses Rs.5 crore and e-way bills apply to goods movements above Rs.50,000. We set up, train and troubleshoot both systems, so your despatches from Sithalapakkam are never held up by a compliance gap at the gate.
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.
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.
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.
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.
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.
We verify your turnover and business type against composition conditions, and file CMP-02 to opt in from the start of the financial year where applicable.
Each quarter we collect your sales summary, apply the correct composition rate, and add any tax payable under reverse charge on specified inward supplies.
The statement-cum-challan in Form CMP-08 is prepared, tax is paid, and the form is filed by the 18th of the month following the quarter.
After year end we consolidate the four quarters, reconcile with your books, and file the annual return in GSTR-4 before the 30 June due date.
We track your cumulative turnover through the year and, if the Rs.1.5 crore or Rs.50 lakh limit nears, manage a clean transition to the regular scheme.
Send these on WhatsApp (+91 - 9600 606 444) and we take it forward the same day.

Practical outcomes our clients measure us by.
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.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
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.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule II, heading 2523 · 2025-09-17
Portland cement, aluminous cement, slag cement, super sulphate cement and similar hydraulic cements, whether or not coloured or in the form of clinkers, appear in Schedule II at nine per cent central tax, giving a combined eighteen per cent from 22 September 2025. Cement had carried twenty-eight per cent since 2017 and was the single largest tax input in construction. Marble, granite and most other building materials also sit at eighteen per cent in the same schedule.
How we apply it: Builders and hardware dealers in Chennai must bill cement at eighteen per cent and should have revisited running contracts and price lists from 22 September 2025.
Tata Consultancy Services v. State of Andhra Pradesh — Supreme Court, (2005) 1 SCC 308, judgment dated 05-11-2004 · 2004-11-05
The Court examined whether canned or branded software sold on floppies and discs could be taxed as goods under sales tax law. It held that the term goods covers all types of movable property, tangible or intangible, provided the item can be abstracted, transmitted, transferred, delivered, stored and possessed. Branded software satisfies that test and is goods, even though the intellectual content is intangible. Customised software developed for a single customer stands on a different footing.
Practical effect: Chennai software and IT product businesses should classify off-the-shelf licences separately from bespoke development, since the goods or services character drives the rate, the place of supply and the e-invoice treatment.
GSTN Advisory, 2021 — negative liability appearing in Form GSTR-4 filed by composition taxpayers · 2021
Composition taxpayers who left Table 6 of the annual return GSTR-4 blank found that the tax already paid through Form CMP-08 was treated as an excess payment, creating a negative liability that was then adjusted against later quarters. GSTN clarified that outward supply and reverse charge figures must be entered in Table 6 even though the tax has already been paid, and arranged for wrongly created negative balances to be reversed.
What it means for you: Composition dealers in Chennai must complete Table 6 of GSTR-4 each year, or the portal will show a false credit and later recover it.
