Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Thirusulam businesses from Rs.749, matching every figure against portal data before anything reaches the department.
Share your number — a senior GST consultant calls you back within 30 minutes.
GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Thirusulam faces Chennai International Airport across GST Road, its quarried hill topped by the Tirusoolanathar Temple and its frontage taken by freight forwarders, air cargo agents, customs brokers, cab fleets and budget lodges near Tirusulam railway station and the Airport Flyover. Zero-rated export freight, place-of-supply calls on international transport and reverse charge on GTA services make these filings unusually technical. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Thirusulam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Meenambakkam and Pallavaram run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.
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.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in Thirusulam would otherwise read about after it lapsed reaches our clients in time.
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.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from Thirusulam regularly visit us for registrations, notice discussions and annual return reviews.
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.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
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.
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.
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.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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, 2021 — negative liability appearing in Form GSTR-4 filed by composition taxpayers · 2021
Composition taxpayers who left Table 6 of the annual return GSTR-4 blank found that the tax already paid through Form CMP-08 was treated as an excess payment, creating a negative liability that was then adjusted against later quarters. GSTN clarified that outward supply and reverse charge figures must be entered in Table 6 even though the tax has already been paid, and arranged for wrongly created negative balances to be reversed.
Practical effect: Composition dealers in Chennai must complete Table 6 of GSTR-4 each year, or the portal will show a false credit and later recover it.
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.
What it means for you: The principle that GSTR-3B is corrected in a subsequent month rather than revised still governs every rectification a Chennai business makes today.
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.
