Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Whether you are a first-time registrant or an established trader, GSTR-1 & GSTR-3B Monthly Filing in Royapuram deserves a specialist rather than a side job. From Rs.749, our GST-focused Chennai practice runs the entire process on written checklists and senior-reviewed submissions.
We serve businesses on and around Kasimedu Fishing Harbour — 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.
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. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Royapuram, Tondiarpet and Old Washermanpet on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Royapuram compete with each other; complete confidentiality is a condition of our work.
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.
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.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
A new GSTIN comes with obligations nobody explains at approval — the invoice series rules, displaying the registration certificate and GSTIN at your premises, and the first return cycle. We walk new registrants in Royapuram through each of these so month one starts correctly.
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.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
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.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
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.
Filed returns, challans, reconciliations and working papers are archived in order from day one. If an audit or departmental verification comes, your file is ready the same week, not assembled in a panic.
| 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. |
| 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. |
| Late fees and interest | Filings go in ahead of statutory dates, so the Rs.50-per-day late fee and 18 percent interest never arise. | Late fees accumulate silently every delayed day, and interest on unpaid tax runs at 18 percent per annum. |
| 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. |
| 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. |

Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I entries for electrically operated vehicles and chargers · 2025-09-17
Electrically operated vehicles including two-wheelers and three-wheelers, fuel cell and hydrogen vehicles, e-bicycles and chargers or charging stations for electric vehicles remain in Schedule I at five per cent. Small petrol cars up to 1200 cc and up to 4000 mm, small diesel cars up to 1500 cc and up to 4000 mm and motorcycles up to 350 cc moved to eighteen per cent, while larger cars, hybrids above those limits and motorcycles above 350 cc were placed at forty per cent.
How we apply it: The tax gap between an electric two-wheeler at five per cent and a petrol motorcycle at eighteen per cent is now the single biggest pricing lever for Chennai vehicle dealers.
GSTN Advisory — negative values in Table 3.1 of GSTR-3B, January 2025 · 2025-01
GSTN enabled reporting of negative values in Table 3.1 of GSTR-3B from the January 2025 period onwards. Where credit notes issued in a month exceed outward supplies, the net negative figure now auto-populates instead of being forced to zero. The resulting negative liability is carried in the taxpayer's records and automatically adjusted against the liability of subsequent tax periods, removing a long-standing distortion for businesses with heavy sales returns.
What it means for you: Businesses with seasonal returns or large credit notes no longer need workarounds; let the negative figure flow and track its set-off next month.
Circular No. 123/42/2019-GST dated 11 November 2019 · 2019-11-11
CBIC explained the newly inserted rule 36(4). The restriction is not supplier-wise but is computed on a consolidated basis for all invoices not appearing in GSTR-2A. The amount of eligible credit is determined from GSTR-2A as on the due date for filing GSTR-1 by suppliers for that month. A taxpayer may therefore claim only twenty per cent more than the credit reflected in GSTR-2A, and the balance may be claimed in a later month once the supplier uploads the invoice.
How we apply it: This circular began the era of credit being tied to supplier filings, and monthly reconciliation of purchases with GSTR-2A or 2B is now unavoidable.
