GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Adyar hosts IT services firms, coaching institutes, banks and premium retail along Lattice Bridge Road, Sardar Patel Road and Gandhi Nagar. Software exporters and freelance consultants billing overseas clients need a fresh LUT in RFD-11 every financial year to invoice without IGST, and many first encounter GST only when foreign receipts cross the Rs.20 lakh services threshold. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Adyar follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Besant Nagar and Thiruvanmiyur run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Adyar always know exactly what the engagement costs them.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Adyar are comfortable with, and keeps written communication simple and jargon-free.
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.
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 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.
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.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
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.
Consistent, reconciled returns give the department's matching systems nothing to flag. Clients who move to us after years of self-filing typically see scrutiny queries and mismatch notices fall away within a few filing cycles.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

GSTN Advisory dated 24 September 2024 — archival of GST returns data older than seven years · 2024-09-24
GSTN advised that return data on the common portal is retained for seven years only, after which it is archived and no longer available for viewing or download. Archival started with the earliest tax periods of 2017-18 and proceeds month by month, so one further month of data drops off the portal every month. Taxpayers were advised to download and preserve their returns and supporting data before the archival date for each period.
What it means for you: Download and store PDF and JSON copies of every GSTR-1, GSTR-3B and GSTR-9 filed since 2017, because archived returns cannot be retrieved from the portal during an audit or appeal.
3rd GST Council Meeting, New Delhi — 18-19 October 2016 (Signed Minutes, Agenda Item 2) · 2016-10-18
The Chairperson offered a compromise between a fixed 13 per cent growth rate, an average of three of the preceding five years' growth after removing the highest and lowest, and a 14 per cent rate pressed by Kerala and Assam. The Council unanimously agreed that projected State revenue for compensation purposes would grow at a flat 14 per cent per year from the 2015-16 base, with CST in that base counted at the actual 2 per cent. This single number determined the size of the compensation bill for the five-year guarantee period and, when actual GST collections fell short of it, drove the compensation cess extensions and the back-to-back borrowing arrangements of later years.
What it means for you: The 14 per cent guarantee is the reason compensation cess outlived its original five-year sunset, so cess-bearing goods remain costlier than the headline GST rate suggests.
Notification No. 33/2020-Central Tax · 2020-04-03
CBIC waived the late fee for furnishing the outward supply statement in Form GSTR-1 for the months of March, April and May 2020 and for the quarter ending 31 March 2020, provided the statement was filed on or before 30 June 2020. The relief covered both monthly and quarterly filers. Because GSTR-1 late fee is separate from GSTR-3B late fee, this notification had to be issued in addition to the GSTR-3B waiver of the same date.
What to do about it: A Chennai supplier who filed the March to May 2020 GSTR-1 by 30 June 2020 owes nothing by way of late fee, whatever the portal ledger may currently show.
