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 Mandaveli 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 Mandaveli MRTS Station — 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.
Mandaveli is a dense middle-class trading strip along R.K. Mutt Road, where provision stores, sweet stalls, silk and readymade shops, banks and the MTC bus terminus serve Mylapore's southern flank, with the Mandaveli Market feeding daily vegetable trade. Most shops are family-run B2C businesses hovering near the Rs.40 lakh goods threshold, so registration timing, composition scheme choice and GSTR-3B late fees dominate consultations. Years of working in and around Mandaveli have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our GSTR-1 & GSTR-3B Monthly Filing is built to close precisely those gaps, and the same team supports businesses in Mylapore and Raja Annamalaipuram, each with one point of contact and a compliance calendar maintained on their behalf.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Mandaveli business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
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.
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 Mandaveli 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.
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.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Mandaveli always know exactly what the engagement costs them.
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

Practical outcomes our clients measure us by.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
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.
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.
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.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| Supplier defaults | Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit. | Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult. |
| 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. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
Saro Enterprises - AAR Tamil Nadu (2018), upheld by AAAR Tamil Nadu, order dated 6 February 2019 · 2018
The applicant made polypropylene and recycled plastic trays used by farmers to raise paddy and vegetable seedlings, and argued that they were agricultural implements. The Authority held that the trays are other articles of plastic under heading 3926 90 99 and are taxable at 9 percent central tax and 9 percent State tax. Use in agriculture does not by itself bring a product within the exempt agricultural implements entry, and the material and the tariff description prevail over the end use.
What to do about it: Chennai suppliers to the farm sector cannot assume exemption merely because the buyer uses the product in agriculture.
30th GST Council Meeting (video conference) — 28 September 2018 (PIB Release ID 1547891) · 2018-09-28
Meeting shortly after the Kerala floods, the Council discussed that State's proposal to impose a cess on SGST to fund rehabilitation and flood-related works. Because GST had removed the States' independent power to levy such a cess, the Council constituted a seven-member Group of Ministers convened by the Deputy Chief Minister of Bihar, with members from Assam, Kerala, Maharashtra, Odisha, Punjab and Uttarakhand, to examine modalities for revenue mobilisation in case of natural calamities and disasters, reporting by 31 October 2018.
How we apply it: This process produced the Kerala flood cess of 2019, the only State-specific GST cess so far, and set the template for how any similar Tamil Nadu levy would have to be approved.
Circular No. 136/06/2020-GST dated 3 April 2020 · 2020-04-03
CBIC explained the relief notified through Notifications 30 to 36 of 2020-Central Tax after the first lockdown. It set out, return by return and class by class, the extended dates for GSTR-3B and GSTR-1, the conditional waiver of interest for the tax periods February to April 2020 with nil interest for the first fifteen days and nine per cent thereafter for larger taxpayers, the waiver of late fee, the relaxation of the rule 36(4) credit restriction, and the extension for composition taxpayers.
Practical effect: Interest and late fee demands for the early 2020 periods must be tested against these concessional rates before they are paid.
