We serve businesses on and around Jayachandran Nagar 1st Main 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.
Choosing GSTR-1 & GSTR-3B Monthly Filing in Medavakkam is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Medavakkam's junction links Velachery, Tambaram, Sholinganallur and Mambakkam, making it one of south Chennai's fastest-selling apartment markets, ringed by builders, hardware and sanitaryware dealers, supermarkets and tuition centres along Medavakkam Main Road and the Sholinganallur route. Promoters using the 1 and 5 per cent residential rates must source at least 80 per cent of inputs from registered suppliers or pay tax on the shortfall under reverse charge. 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 Medavakkam, Pallikaranai and Madipakkam 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.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
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.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
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 Medavakkam, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
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.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
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.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| Time cost | Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours. | Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself. |
| 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. |
| 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. |
Jayachandran Nagar 1st Main Road is a residential street in Medavakkam, about 950 m east of the centre of Medavakkam.

GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
Circular No. 186/18/2022-GST · 2022-12-27
The Board clarified two unrelated points. A no claim bonus allowed by an insurer is a permissible discount under Section 15(3)(a) and may be deducted from the value of the insurance service, provided it is shown in the invoice. Separately, where an entity is exempt from the requirement to issue e-invoices, that exemption attaches to the entity as a whole and covers all its supplies, including supplies unrelated to the activity that gave rise to the exemption.
Why this matters: An exempt category business such as a bank, insurer or goods transport agency in Chennai need not issue e-invoices for any of its supplies, not merely its core activity.
36th GST Council Meeting (video conferencing) — 27 July 2019 · 2019-07-27
The Council reduced GST on all electric vehicles from 12 per cent to 5 per cent and on chargers or charging stations for electric vehicles from 18 per cent to 5 per cent. Hiring of electric buses with carrying capacity of more than twelve passengers by local authorities was exempted. All these changes took effect from 1 August 2019. The Council also extended the last date for opting into the six per cent service composition scheme in CMP-02 to 30 September 2019.
Why this matters: Electric vehicle dealers and charging point operators in Chennai bill at five per cent, a rate that has survived every later rate revision including GST 2.0.
Entry 21, Notification No. 12/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
Entry 21 exempted goods transport agency services for agricultural produce, milk, salt, food grain including flour, pulses and rice, organic manure, registered newspapers and magazines, disaster relief materials and defence equipment. It also carried two value-based exemptions, for a single consignment charged at not more than one thousand five hundred rupees and for all goods for a single consignee charged at not more than seven hundred and fifty rupees. Both value limbs were withdrawn from 18 July 2022.
What to do about it: Chennai businesses should stop relying on the old rupees fifteen hundred and seven hundred fifty freight exemptions, since small freight bills after 18 July 2022 attract reverse charge.
