Reliable GSTR-1 & GSTR-3B Monthly Filing for Adyar businesses at a clear, fixed fee starting Rs.749. We handle the documentation, portal work and follow-up, you approve the draft before anything is filed, and the acknowledgement reaches you on WhatsApp the moment the filing goes through.
We serve businesses on and around Parameswari Nagar — 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.
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.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in Adyar would otherwise read about after it lapsed reaches our clients in time.
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.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
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 Adyar regularly visit us for registrations, notice discussions and annual return reviews.
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 Adyar are never held up by a compliance gap at the gate.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
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.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
| 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. |
| 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. |
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 5) · 2017-01-16
With the revised model law still to be brought back to the Council, the fitment of rates incomplete and taxpayers needing time to configure their accounting systems, the Council unanimously agreed to extend the GST rollout date to 1 July 2017. Maharashtra, Assam and Bihar had pressed for 1 April 2017, Assam adding that changing the tax regime in the middle of a financial year was undesirable, but the Chairperson observed that the legal and rate work would spill into March 2017 and that an April deadline had become a major challenge. Tamil Nadu and Karnataka supported 1 July 2017 as the more practical date.
How we apply it: GST law in India runs from 1 July 2017, so the first return periods, the first annual return and all transitional credit deadlines are measured from that date.
Notification No. 83/2020-Central Tax · 2020-11-10
From January 2021 the outward supply statement in Form GSTR-1 became due on the 11th day of the month following the tax period for monthly filers. For registered persons furnishing GSTR-1 quarterly under the new scheme, the statement became due on the 13th day of the month following the quarter. This replaced the earlier practice of notifying due dates a few months at a time and gave the return calendar a stable shape that has continued since.
What it means for you: The 11th and the 13th are the fixed GSTR-1 dates for a Chennai business, and missing them delays credit for every customer you supply.
Tamil Nadu Water Investment Company Ltd - AAR Tamil Nadu, advance ruling reported at 2019 (2) TMI 187 · 2019
The Chennai company provided management consultancy and detailed project report services to the Chennai Metro Water Supply and Sewerage Board for water related projects. It asked whether the service attracted GST. The Authority held that the supply was a pure service with no supply of goods involved, rendered in relation to a function entrusted to a municipality, and was therefore exempt from GST under the entry covering pure services supplied to government and local authorities.
What to do about it: Chennai consultants on government water and civic projects should test the pure services exemption before adding GST to their invoices.
