GSTR-1 & GSTR-3B Monthly Filing in Royapuram does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Amman Koil Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

If you operate in Royapuram, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. Royapuram lives off the sea and the port: the Kasimedu fishing harbour drives seafood traders, processors and exporters, while Cochrane Basin Road and Thiruvottiyur High Road host logistics yards, cold storages and marine hardware suppliers. Seafood exporters here must keep the LUT under RFD-11 renewed every financial year and chase RFD-01 refunds within the two-year window, which is the area's biggest GST task. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Royapuram and the adjoining Tondiarpet and Old Washermanpet localities, maintaining a compliance calendar for every client so due dates are met without last-minute panic, late fees or interest at 18 percent per annum.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in Royapuram, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
New GSTIN applications, core field amendments through REG-14, additional places of business — we prepare complete, query-resistant applications the first time. Clean paperwork is the difference between smooth approval and weeks lost answering clarification memos from the department.
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 Royapuram never leave marketplace deductions unclaimed.
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.
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.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
Amman Koil Street is a residential street in Royapuram, about 2.4 km south-west of the centre of Royapuram. The same consultant covers the streets immediately around it — Cochrane Basin Road (about 800 m); Old Jail Road (about 1.1 km); Dhakshina Murthy Koil Street (about 1.2 km); Monegar Choultry Road (about 1.3 km) — so a site visit on Amman Koil Street can usually be combined with other work in Royapuram on the same trip. For GST purposes an address on Amman Koil Street falls under the Chennai North CGST Commissionerate, and the Royapuram pincode is 600013.

Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I, renewable energy devices entry · 2025-09-17
Biogas plants, solar power based devices and generators, solar lanterns and lamps, windmills and wind operated electricity generators, waste-to-energy plants, ocean and tidal wave energy devices and photovoltaic cells whether or not assembled into modules or panels are all listed in Schedule I at five per cent from 22 September 2025, reversing the increase made in October 2021. The explanation deeming seventy per cent of a composite project contract to be the value of goods has been carried forward unchanged.
Practical effect: Rooftop solar installers in Chennai bill the goods component at five per cent using the 70:30 split, which materially lowers the delivered cost of a project.
Mr. Kannippan Arumugan v. Assistant Commissioner (ST) — Madras High Court, W.P. No. 2943 of 2026, decided 30 January 2026 (C. Saravanan J.) · 2026-01-30
The taxpayer had reported tax of Rs 2,54,040.30 against an invoice instead of the correct Rs 1,31,280.30, and a demand followed. The Court quashed the assessment order dated 21 July 2025 and remitted the matter for fresh adjudication within six months, permitting the petitioner to rectify the inadvertent error subject to compliance with Circular No. 212/6/2024-GST, and directing the officer to verify with the recipient's jurisdiction whether excess credit had in fact been availed.
What it means for you: A clerical overstatement in GSTR-1 by a Chennai supplier can still be corrected long afterwards, provided the recipient has not taken the excess credit and the Circular 212 procedure is followed.
GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
How we apply it: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
