Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-9C Reconciliation is completed on the portal from Rs.9,999 — by a Chennai team that businesses across Mathur MMDA have relied on for years.
Share your number — a senior GST consultant calls you back within 30 minutes.
Mathur MMDA is the Housing Board and MMDA township laid out in numbered main, cross and serial streets off Kamarajar Salai, between the Inner Ring Road and Madhavaram Milk Colony Road. Contractors, fabricators, tanker operators and labour suppliers serving the Manali petrochemical belt at MFL and CPCL sit alongside colony supermarkets, bakeries and hardware shops. Works-contract classification, TDS under Section 51 from PSU buyers and GSTR-2B mismatches dominate the compliance load. Years of working in and around Mathur MMDA have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our GSTR-9C Reconciliation is built to close precisely those gaps, and the same team supports businesses in Manali and Manali New Town, 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.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
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.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
A new GSTIN comes with obligations nobody explains at approval — the invoice series rules, displaying the registration certificate and GSTIN at your premises, and the first return cycle. We walk new registrants in Mathur MMDA through each of these so month one starts correctly.
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 Mathur MMDA regularly visit us for registrations, notice discussions and annual return reviews.
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.
We collect audited financial statements, trial balance, filed returns and the ITC register, and confirm the GSTIN-wise turnover where the entity has multiple registrations.
Book turnover is adjusted for unbilled revenue, advances, credit notes and non-GST income to derive turnover as per GST, matching it against GSTR-9 declarations.
We reconcile rate-wise tax paid with the liability per financials, and map input tax credit claimed to expense heads in the books as GSTR-9C requires.
Each unreconciled amount is investigated, documented with reasons in the statement, and any genuine shortfall is quantified with interest for payment through DRC-03.
The final statement is walked through with you, self-certified, and filed on the portal along with GSTR-9 before 31 December, with working papers handed over.
Send these on WhatsApp (+91 - 9600 606 444) and we take it forward the same day.
Timeline: 7-10 working days; statutory due date 31 December · No hidden charges · GST invoice provided
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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 business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
| 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. |
| 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. |
| Registration and amendments | Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify. | Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
GSTN Advisory dated 9 December 2024 — GSTR-9/9C for FY 2023-24 · 2024-12-09
For FY 2023-24 onwards, Table 8A of the annual return GSTR-9 is auto-populated from GSTR-2B instead of GSTR-2A, following Notification No. 12/2024 and 20/2024-Central Tax. GSTN's advisory explains scenario-wise how invoices of one year appearing in the next year's GSTR-2B should be reported, why differences between Table 8A and manually entered Table 8C can legitimately arise, and how to reconcile ITC across Tables 8, 12 and 13.
Why this matters: Prepare a GSTR-2B based ITC reconciliation before filing GSTR-9, and document genuine 8A versus 8C timing differences to answer later scrutiny.
Circular No. 180/12/2022-GST · 2022-09-09
Following the Supreme Court directions in Union of India versus Filco Trade Centre, the Board issued guidelines allowing every aggrieved taxpayer to file or revise FORM GST TRAN-1 and TRAN-2 on the common portal during a special window from 1 October 2022 to 30 November 2022. The circular set out the declaration to be filed, the requirement to submit a self-certified copy to the jurisdictional officer, and the verification timelines that follow the filing.
What to do about it: Transitional credit disputes from 2017 that reached the courts were routed through this one-time window, and any pending verification of a Chennai taxpayer's TRAN filing is governed by these guidelines.
Notification No. 08/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
Section 9(4) of the CGST Act as originally enacted made a registered person liable to pay tax under reverse charge on all inward supplies received from unregistered persons. This notification granted a de minimis exemption where the aggregate value of such supplies received from all unregistered suppliers did not exceed Rs 5,000 in a day. The exemption proved unworkable in practice and section 9(4) was soon suspended altogether.
How we apply it: This threshold only matters for the July to October 2017 period, and Chennai businesses still facing scrutiny for those months should check the daily aggregate rather than invoice-wise values.
