Businesses in St. Thomas Mount looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. St. Thomas Mount combines the cantonment economy around Butt Road with airport-linked logistics, guest houses and retail on GST Road. Contractors and suppliers billing the Cantonment Board and defence establishments face 2 per cent GST TDS, which deductors report in GSTR-7 by the 10th, so vendors must accept and reconcile those credits monthly to avoid cash-flow leakage. We serve this belt — including Alandur and Guindy — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
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.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
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.
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 St. Thomas Mount always know exactly what the engagement costs them.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in St. Thomas Mount never leave marketplace deductions unclaimed.
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.
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.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
When a query or verification comes, you respond through a professional who deals with the department regularly, in the department's own language and format, instead of facing an officer's letter alone.
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.
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.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |

Circular No. 141/11/2020-GST dated 24 June 2020 · 2020-06-24
This circular explained Notifications 51, 52 and 53 of 2020-Central Tax issued on the recommendations of the 40th GST Council meeting. The rate of interest was reduced from eighteen to nine per cent for specified periods, and for small taxpayers it was staggered, with nil interest up to a specified date and nine per cent thereafter until 30 September 2020. The conditional waiver of late fee on GSTR-3B was given revised dates for February to April 2020 and extended to May, June and July 2020 for small taxpayers, and late fee on delayed GSTR-1 was waived if filed by the specified dates. Circular No. 136/06/2020-GST was modified to this extent.
Practical effect: The late fee waiver here is conditional: if the GSTR-3B was not filed by the notified date, late fee runs from the original due date, so the actual filing date decides whether any waiver survives.
M/s. New PSP Traders v. Deputy State Tax Officer — Madras High Court (Madurai Bench), W.P.(MD) No. 17026 of 2025, decided 25 June 2025 (C. Saravanan J.) · 2025-06-25
The assessment orders had denied input tax credit purely because the returns were filed after the Section 16(4) cut-off. The Court held that the challenge was squarely covered by newly inserted Section 16(5), which permits credit on invoices relating to the financial years 2017-18 to 2020-21 if taken in any return filed up to 30 November 2021, notwithstanding Section 16(4). The impugned orders were quashed and the matter remitted for fresh orders consistent with the amendment.
What to do about it: A Chennai dealer whose ITC for 2017-18 to 2020-21 was disallowed only for late filing should apply for rectification or move the High Court, since Section 16(5) now protects that credit.
23rd GST Council Meeting, Guwahati — 10 November 2017 (PIB Release ID 1509013) · 2017-11-10
The Council decided that all taxpayers would file GSTR-3B with payment of tax by the 20th of the succeeding month until March 2018, and that for GSTR-1 taxpayers would be divided by turnover. Those with annual aggregate turnover up to Rs 1.5 crore would file GSTR-1 quarterly, and those above that figure monthly, with a detailed table of due dates. Filing of GSTR-1 was to continue without requiring GSTR-2 and GSTR-3 for the previous period.
How we apply it: The turnover-based split between monthly and quarterly GSTR-1 that still determines a Chennai business's filing calendar was created here.
