Complete GSTR-1 & GSTR-3B Monthly Filing in Chromepet from Rs.749 — documentation, preparation, filing and acknowledgement, all managed by one accountable team. One call or WhatsApp message starts the process, and you get a same-working-day response.
We serve businesses on and around MIT Road — 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.
Chromepet grew around the old Chrome Leather Company and now centres on the MIT campus, hospitals, private hostels and dense retail along GST Road and Radha Nagar. Hostels and coaching centres frequently misjudge GST applicability on accommodation and fees, and GST Road retailers see recurring GSTR-1 versus GSTR-3B turnover mismatches that invite ASMT-10 notices requiring an ASMT-11 reply within 30 days. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Chromepet businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Pallavaram and Tambaram on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
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.
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.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Chromepet business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
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.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
Rule 88C, CGST Rules, 2017, inserted by Notification No. 26/2022-Central Tax · 2022-12-26
Rule 88C requires the portal to intimate a taxpayer in Form GST DRC-01B whenever the output tax liability declared in GSTR-1 for a period exceeds the liability paid through GSTR-3B beyond the prescribed limit. The taxpayer must either pay the shortfall with interest through Form DRC-03 or furnish an explanation in Part B of DRC-01B within seven days. The facility went live on the portal from mid-2023 and an unanswered intimation blocks the next GSTR-1.
Why this matters: Reconcile GSTR-1 against GSTR-3B every month, because a DRC-01B intimation left unanswered for seven days will freeze your next outward supplies return.
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.
What it means for you: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
Circular No. 167/23/2021-GST dated 17 December 2021 · 2021-12-17
Following the 45th GST Council meeting, restaurant service supplied through an e-commerce operator was notified under section 9(5) with effect from 1 January 2022. CBIC clarified that the operator, and not the restaurant, is liable to pay the tax on such supplies, must discharge it in cash without using input tax credit, and issues the invoice for the service. The restaurant continues to pay tax on its own dine-in and direct sales, and the aggregate turnover of the restaurant still includes the supplies made through the platform.
How we apply it: Chennai restaurants listed on delivery platforms must separate platform sales from direct sales in their records, because the tax on the former is paid by the platform.
