We serve businesses on and around Devadoss Street — 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. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Mugalivakkam for years, along with clients from Manapakkam and Ramapuram. 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.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
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 Mugalivakkam compete with each other; complete confidentiality is a condition of our work.
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.
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 Mugalivakkam regularly visit us for registrations, notice discussions and annual return reviews.
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.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
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.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Devadoss Street is a residential street in Mugalivakkam, about 1.5 km west of the centre of Mugalivakkam. The same consultant covers the streets immediately around it — Ponniamman Koil Salai (about 300 m); Sarojini Street (about 350 m); Othavadai Street (about 550 m); Ramasamy Nagar Main Road (about 550 m) — so a site visit on Devadoss Street can usually be combined with other work in Mugalivakkam on the same trip. For GST purposes an address on Devadoss Street falls under the Chennai South CGST Commissionerate, and the Mugalivakkam pincode is 600116.

Krishna Bhavan Foods and Sweets - AAR Tamil Nadu, Order No. TN/24/AAR/2021, dated 18 June 2021, upheld by AAAR Tamil Nadu, Order No. TN/AAAR/02/2022, dated 13 January 2022 · 2021-06-18
The applicant sold packaged ready to cook instant mixes for dosai, idli, tiffin items, sweets, health mix and porridge. It argued that these were only flours of cereals and pulses taxable at 5 percent. The Authority classified the products under heading 2106 90 as food preparations not elsewhere specified, attracting 18 percent GST, because the mixing and added ingredients took them out of the concessional flour entries. The Appellate Authority upheld that classification.
What it means for you: Chennai food manufacturers selling instant mixes should confirm whether the product is a plain flour or a preparation before applying 5 percent.
K.P. Mozika v. Oil and Natural Gas Corporation Ltd — Supreme Court, Civil Appeal No. 3548 of 2017, judgment dated 09-01-2024 · 2024-01-09
The Supreme Court examined contracts for supplying cranes, tankers and vehicles to ONGC. It held that a transfer of the right to use goods requires the customer to obtain effective control and legal right to use the goods to the exclusion of the owner. Where the owner retains the operator, control and responsibility, the arrangement is a service contract and not a deemed sale. Sales tax or VAT was therefore not attracted; service tax was.
How we apply it: Chennai transport, crane and equipment hire businesses should draft contracts carefully, since who controls the asset decides whether GST applies as a supply of service or of goods.
GSTN rollout of Form GSTR-1A pursuant to Notification No. 12/2024-Central Tax, dated 10 July 2024 · 2024-07
Through Notification No. 12/2024-Central Tax and subsequent portal rollout, Form GSTR-1A was reintroduced. It lets a taxpayer amend or add records of the same tax period after filing GSTR-1 but before filing that period's GSTR-3B, so the corrected liability auto-populates into GSTR-3B. Amendments flow to the buyer's GSTR-2B of the next period, and the recipient GSTIN itself cannot be changed through GSTR-1A.
Why this matters: Use GSTR-1A to fix invoice errors in the same month instead of carrying mistakes forward, especially now that GSTR-3B figures are hard-locked.
