The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Mylapore permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Papanasam Sivan Salai — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Choosing GSTR-1 & GSTR-3B Monthly Filing in Mylapore is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Mylapore runs on gold jewellery, silk sarees and temple-linked retail concentrated on North Mada Street, Luz Church Road and R.K. Mutt Road around Kapaleeswarar Temple. Jewellers face HSN and old-gold exchange valuation issues, while saree and provision traders approaching the Rs.40 lakh registration threshold or the Rs.1.5 crore composition ceiling need disciplined turnover tracking and punctual GSTR-1 filing. We earn that trust the unglamorous way — fixed fees honoured, drafts approved by you before filing, acknowledgements shared the same day, and strict confidentiality throughout. Clients across Mylapore, Alwarpet and Mandaveli have stayed with us for years on precisely this basis.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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 Mylapore through each of these so month one starts correctly.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
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.
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.
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 Mylapore are never held up by a compliance gap at the gate.
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.
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.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
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.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 3) · 2017-01-16
The dual-control deadlock that had stalled several earlier meetings was broken. The Council agreed that taxpayers would be divided between Central and State tax administrations for all administrative purposes: of taxpayers with turnover below Rs 1.5 crore, 90 per cent would go to the State administration and 10 per cent to the Centre, while taxpayers above Rs 1.5 crore would be split equally. Division was to be by computerised stratified random sampling at the State level, with both administrations retaining intelligence-based enforcement powers over the whole value chain. West Bengal recorded its dissent.
What to do about it: This is why a Chennai taxpayer is assigned either to the Tamil Nadu Commercial Taxes Department or to CGST Chennai, and why notices come from only one of them for routine matters.
GSTN Advisory dated 23 August 2024 — introduction of the RCM Liability/ITC Statement · 2024-08-23
GSTN introduced a new RCM Liability and ITC Statement on the portal so that reverse charge tax declared in Table 3.1(d) of GSTR-3B can be matched against the corresponding credit claimed in Table 4A(2) and 4A(3). It applies from the August 2024 tax period for monthly filers and from the July to September 2024 quarter for taxpayers under the quarterly scheme. Taxpayers were required to report an opening balance of reverse charge liability paid but credit not yet claimed, or credit claimed without payment, within the window announced by GSTN.
What to do about it: Reconcile reverse charge payments with the credit taken every month, since the department can now see an RCM ledger for your GSTIN.
Circular No. 26/26/2017-GST dated 29 December 2017 · 2017-12-29
This consolidated circular explained the return filing decisions of the 23rd GST Council meeting. It clarified the due dates, the quantum of late fee, and, most usefully, that errors in a GSTR-3B already filed cannot be revised but must be corrected by adjusting the figures in the return of a later month, with interest payable where tax was short paid. It also dealt with returns that were submitted but not filed because of portal problems.
Why this matters: The principle that GSTR-3B is corrected in a subsequent month rather than revised still governs every rectification a Chennai business makes today.
