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 GSTR-1 & GSTR-3B Monthly Filing for Mugalivakkam businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Sterling Avenue Main 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.
Mugalivakkam sits between Porur and Manapakkam, its AGS Colony, Sabari Nagar, Sakthi Nagar, Mahalakshmi Nagar and VGN Lakshmi Nagar layouts packed with apartment blocks over ground-floor shops on Mugalivakkam Main Road. Builders, interior and aluminium fabricators, hardware and tile dealers, supermarkets and PG operators trade here. Joint-development revenue recognition, the one-third land abatement, reverse charge on commercial rent and Rule 42 credit reversal on exempt flat sales are the standard questions. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Mugalivakkam businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Manapakkam and Ramapuram on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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 Mugalivakkam never leave marketplace deductions unclaimed.
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 Mugalivakkam never writes back to you as a demand years later.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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.
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.
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
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.
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.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Sterling Avenue Main Road is a residential street in Mugalivakkam, about 1.0 km north-west of the centre of Mugalivakkam. The same consultant covers the streets immediately around it — Ganesh Anenue 2nd Street (about 150 m); Ganesh Avenue 6th Street (about 150 m); 2nd Street (about 250 m); Parvathi Avenue 6th Street (about 250 m) — so a site visit on Sterling Avenue Main Road can usually be combined with other work in Mugalivakkam on the same trip. For GST purposes an address on Sterling Avenue Main Road falls under the Chennai South CGST Commissionerate, and the Mugalivakkam pincode is 600116.

GSTN Advisory, 2022 — Phase-II of mandatory HSN reporting in Table 12 of GSTR-1 from 1 November 2022 · 2022-11-01
Mandatory HSN reporting in Table 12 of GSTR-1 was introduced in phases from 1 April 2022, when the portal began flagging missing or short codes in warning mode. In Phase-II, from the November 2022 return period, taxpayers with annual aggregate turnover up to Rs 5 crore had to report at least four-digit HSN codes for all business-to-business supplies in Table 12, and taxpayers above Rs 5 crore had to report six digits for all supplies. Phase-III in 2025 went further and replaced manual entry with selection from a dropdown of valid codes.
What to do about it: Correct HSN codes once at the item-master level, so that each successive tightening of portal validation does not force fresh rework.
Circular No. 136/06/2020-GST dated 3 April 2020 · 2020-04-03
CBIC explained the relief notified through Notifications 30 to 36 of 2020-Central Tax after the first lockdown. It set out, return by return and class by class, the extended dates for GSTR-3B and GSTR-1, the conditional waiver of interest for the tax periods February to April 2020 with nil interest for the first fifteen days and nine per cent thereafter for larger taxpayers, the waiver of late fee, the relaxation of the rule 36(4) credit restriction, and the extension for composition taxpayers.
What it means for you: Interest and late fee demands for the early 2020 periods must be tested against these concessional rates before they are paid.
