Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-1 & GSTR-3B Monthly Filing is completed on the portal from Rs.749 — by a Chennai team that businesses across Kathivakkam have relied on for years.
We serve businesses on and around Bharathiyar 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.
Kathivakkam is a fishing town wedged between the Ennore Creek and the Chennai-Ennore Expressway, where Thazhankuppam and Ernavur kuppams supply fish traders and ice plants, and works contractors serve the Ennore Thermal Power Station, Ennore Foundries and the container traffic moving down Manali High Road. Labour and works contractors here face reverse charge and GST-TDS issues, and fish traders need clarity on exempt versus processed supplies. That commercial character shapes the GST questions we see from Kathivakkam every week — registrations, monthly returns, credit mismatches and departmental queries. We deliver GSTR-1 & GSTR-3B Monthly Filing for businesses in Kathivakkam, and clients also reach us from Ennore and Ernavur nearby. Documents move over WhatsApp, drafts are approved before filing, and a senior consultant reviews every submission, so distance from our office never dilutes the quality of the work.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
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 Kathivakkam always know exactly what the engagement costs them.
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 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.
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.
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 Kathivakkam are comfortable with, and keeps written communication simple and jargon-free.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
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.
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.
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.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| 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. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
23rd GST Council Meeting, Guwahati — 10 November 2017 (PIB Release ID 1509013) · 2017-11-10
The Council decided that all taxpayers would file GSTR-3B with payment of tax by the 20th of the succeeding month until March 2018, and that for GSTR-1 taxpayers would be divided by turnover. Those with annual aggregate turnover up to Rs 1.5 crore would file GSTR-1 quarterly, and those above that figure monthly, with a detailed table of due dates. Filing of GSTR-1 was to continue without requiring GSTR-2 and GSTR-3 for the previous period.
How we apply it: The turnover-based split between monthly and quarterly GSTR-1 that still determines a Chennai business's filing calendar was created here.
The Bank of Nova Scotia - AAR Tamil Nadu, Order No. TN/23/AAR/2018, dated 31 December 2018 · 2018-12-31
The bank imported goods and stored them in a Free Trade Warehousing Zone before they were cleared. It asked whether integrated tax was payable again when the goods were removed from the zone to the domestic tariff area, over and above the tax collected at the time of customs clearance. The Authority, following Circular No. 3/1/2018-IGST dated 25 May 2018, held that the applicant is not liable to pay IGST at the time of removal, the levy arising once at clearance for home consumption.
What it means for you: Chennai importers using FTWZ facilities pay IGST once at clearance and should resist any demand for a second levy on removal.
Notification No. 38/2020-Central Tax · 2020-05-05
The Central Goods and Services Tax (Fifth Amendment) Rules, 2020 permitted a registered person with no outward supplies, no input tax credit and no tax liability to furnish a nil GSTR-3B through a short message service from the registered mobile number, verified by a one-time password. The same amendment allowed registered persons who are companies to verify returns using an electronic verification code instead of a digital signature certificate, a concession first given during the lockdown.
Why this matters: A dormant Chennai GSTIN can be kept compliant by SMS filing at no cost, which is far cheaper than allowing returns to lapse and inviting cancellation.
