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. GST compliance in a market like Kathivakkam rewards consistency — returns that match, credits that reconcile, and records that stand up to scrutiny. Our team provides GSTR-1 & GSTR-3B Monthly Filing to businesses throughout Kathivakkam and nearby Ennore and Ernavur on fixed, transparent fees. From the first document checklist to the final acknowledgement on WhatsApp, the process is structured so nothing depends on memory, luck or a due-date-evening scramble.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
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 Kathivakkam are never held up by a compliance gap at the gate.
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.
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.
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.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
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.
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.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
GSTN Advisory, November 2024 — 30-day IRP reporting limit for AATO Rs 10 crore and above · 2024-11
GSTN advised that from 1 April 2025, taxpayers with annual aggregate turnover of Rs 10 crore and above cannot report e-invoices on the Invoice Registration Portals beyond 30 days from the document date. The restriction, earlier applicable only to very large taxpayers of Rs 100 crore and above, covers invoices, credit notes and debit notes. The IRP validation simply rejects documents older than 30 days, so late reporting becomes impossible.
Practical effect: Automate same-day or same-week IRN generation, because an invoice missed beyond 30 days cannot be e-invoiced at all and endangers the buyer's ITC.
Notification No. 13/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
This notification specifies the categories of services under section 9(3) on which the whole of the tax is payable by the recipient rather than the supplier. The original list covers goods transport agency services, legal services by an individual advocate or firm of advocates, arbitral tribunal services, sponsorship, most services supplied by the Central or State Government or a local authority, services of a director to a company, insurance agent services, recovery agent services and certain transport and copyright services. Entries have been added over the years.
How we apply it: This is the working reverse charge checklist for a Chennai business, and lorry freight, advocate fees and director remuneration are the entries that most often go unreported.
LC Infra Projects (P) Ltd v. Union of India — Karnataka High Court, judgment dated 22 July 2019 · 2019-07-22
The department demanded interest for delayed payment of tax and attached the taxpayer's bank account without first issuing any show cause notice. The High Court held that issuance of a show cause notice is a mandatory pre-condition before recovery of interest, because the taxpayer must have an opportunity to dispute the period and the computation. The recovery action and the bank attachment were quashed, with liberty to the department to proceed afresh after proper notice.
What to do about it: Interest cannot be lifted from your bank account without warning — insist on a show cause notice and a chance to verify the calculation.
