Question 1

Which GST office handles St. Thomas Mount businesses?

Accepted Answer

Businesses in St. Thomas Mount (PIN 600016) generally fall under the CGST Chennai South Commissionerate, with state-jurisdiction cases handled by the Tamil Nadu Commercial Taxes Department. Your exact division and range can be confirmed from your GSTIN on the GST portal. We regularly appear before this jurisdiction for registrations, clarifications and hearings, so we know the local practice and documentation preferences.

Question 2

Can I get GSTR-1 & GSTR-3B monthly filing done online without visiting the office?

Accepted Answer

Yes, the entire process can be handled online. You share scanned documents on WhatsApp or email, we prepare and file everything on the GST portal, and you receive the acknowledgement and filed copies digitally. Businesses in St. Thomas Mount regularly complete monthly returns with us without a single office visit. If a physical verification or personal hearing is required by the department, we guide you through it.

Question 3

When is GSTR-1 due for my business in St. Thomas Mount?

Accepted Answer

GSTR-1, the statement of outward supplies, is due on the 11th of the following month for taxpayers filing monthly. If you have opted for the QRMP scheme, the quarterly GSTR-1 is due on the 13th of the month after the quarter ends. Filing on time matters because your invoices flow into your buyers' GSTR-2B, which decides their input tax credit. Our team in St. Thomas Mount tracks these dates for every client so nothing slips. Call +91 - 9600 606 444 if you need a filing reminder set up.

Question 4

How do I handle GST when expired medicines are returned to the distributor?

Accepted Answer

CBIC Circular 72/46/2018 gives two routes for time-expired drugs. The return can be treated as a fresh supply by the person returning them, with a tax invoice if that person is registered, or the original supplier can issue a credit note under Section 34; the tax adjustment on a credit note is available only if it is reported within the statutory window, now 30 November following the financial year of supply. Where the manufacturer ultimately destroys the expired stock, input tax credit relating to the destroyed goods must be reversed under Section 17(5)(h). Pharmacies should reconcile expiry returns quarterly; call +91 - 9600 606 444 for help.

Question 5

I generate e-invoices. Do I still have to prepare GSTR-1 separately?

Accepted Answer

If your aggregate turnover exceeds Rs.5 crore, e-invoicing is mandatory and the invoice details reported to the Invoice Registration Portal auto-populate into your GSTR-1. However, auto-population is not a substitute for review. B2C sales, exports without IRN issues, credit notes, amendments and advances still need to be verified or added manually before submission. We review the auto-drafted GSTR-1 against your books each month so that what is filed matches your accounts exactly. If you have just crossed the Rs.5 crore threshold, call +91 - 9600 606 444 and we will set up e-invoicing correctly.

Question 6

My medical shop also sells supplements, cosmetics and baby products. Do they all take the medicine rate?

Accepted Answer

No, and this is where pharmacies slip. Only items answering the description of drugs and medicaments take 5% or nil. Nutraceuticals and protein supplements generally attract 18%, beauty and makeup preparations 18%, while daily-use items such as soaps, shampoos and toothpaste came down to 5% in September 2025. Each product must be mapped to its own HSN code and rate in your billing software, and your GSTR-1 HSN summary must reflect that mix. A single wrong default rate applied across the counter creates either short payment or overcharging. ChennaiGST runs product-master audits for pharmacies in St. Thomas Mount; call +91 - 9600 606 444 to schedule one.

Question 7

My workshop bills customers for spare parts and labour together. How should GST be charged?

Accepted Answer

The accepted practice, supported by CBIC's clarification on servicing, is that where the invoice separately shows the value of parts and the value of labour, each takes its own treatment: parts as a supply of goods and repair labour as a service at 18%. Since auto components also moved to 18% from September 2025, both lines of a typical job card now carry the same rate, which removes the old temptation to shift value between parts and labour. Still keep the split, because HSN and SAC reporting in GSTR-1 differ for goods and services. Workshops can call +91 - 9600 606 444 for invoice-format templates.

Question 8

How should I raise invoices on foreign clients and report them in my returns?

Accepted Answer

You may invoice in foreign currency, but your GST records must state the value in rupees. An export invoice under LUT should carry the endorsement that the supply is meant for export under Letter of Undertaking without payment of integrated tax, along with your GSTIN, SAC code and the recipient's overseas address. In GSTR-1, these invoices go into Table 6A marked without payment of tax, and the turnover flows into GSTR-3B as zero-rated supplies. Match every invoice to a FIRC or bank credit. Our filing package for exporters in St. Thomas Mount includes this export documentation at Rs.749 per month.

Question 9

My supplier is delivering one order in several instalments. When can I claim the ITC?

Accepted Answer

Where goods against a single invoice are received in lots or instalments, the first proviso to Section 16(2) permits the credit only upon receipt of the last lot. So if machinery invoiced in March arrives in four consignments ending in May, the entire ITC is claimable only in May, even though the invoice is dated March. Claiming it earlier is a premature availment that can be flagged in scrutiny. Track part deliveries against invoices in your inward register, and defer the credit in your reconciliation working until the final consignment is booked. This timing point is routinely missed by businesses in St. Thomas Mount handling bulk orders.

Question 10

My buyer has not accepted my credit note. Does that affect my tax reduction?

Accepted Answer

Yes. Your output tax reduction on a credit note is conditional on the corresponding input tax credit being reversed by the recipient. On the portal, the Invoice Management System now presents your credit notes to the buyer for action, and a rejected credit note flows back into your liability computation. Practically, this means credit notes need commercial agreement before they are reported, not after. Keep an email trail with the buyer, confirm they will reverse the credit in their GSTR-3B, and reconcile IMS actions monthly. ChennaiGST tracks credit note acceptance for St. Thomas Mount clients as part of the monthly filing cycle.

Question 11

I make both taxable and exempt supplies. How is the Rule 42 credit reversal actually computed?

Accepted Answer

Rule 42 first removes credit exclusively for exempt supplies and non-business use, and credit exclusively for taxable supplies, leaving the common credit. From this common pool, you reverse the portion equal to exempt turnover divided by total turnover for the month, plus a flat five percent of the common credit where inputs are partly used for non-business purposes. The reversal is declared monthly in GSTR-3B, and a final recomputation for the whole year must be done, with any shortfall paid with interest, by the November return following the financial year. Traders in St. Thomas Mount dealing in items like unbranded foods alongside taxable goods need this working every month.

Question 12

We hire cabs monthly for employee transport in St. Thomas Mount. Who pays the GST?

Accepted Answer

If the cab operator is not a body corporate, charges 5 percent, and your business is a body corporate, the liability shifts to you under reverse charge. The entry covers renting of motor vehicles designed to carry passengers where the cost of fuel is included in the consideration. If the operator is itself a company, or bills at the higher rate with full ITC, 18 percent since the September 2025 rate rationalisation, forward charge applies and the operator collects the tax. Remember that even after paying RCM, the ITC on employee transport in vehicles seating up to thirteen is blocked under Section 17(5) unless providing the transport is obligatory for the employer under a law.

Question 13

We sponsored a trade event. Does reverse charge apply to the sponsorship amount?

Accepted Answer

If your business is a body corporate or partnership firm, sponsorship services received are notified under Section 9(3) and you must pay 18 percent GST under reverse charge, with ITC available since sponsorship is a marketing expense. One recent change matters: with effect from 16 January 2025, sponsorship services provided by a body corporate were moved to forward charge, so if the event organiser billing you is a company, it now charges GST on its invoice and RCM does not apply. Where the provider is a proprietor, trust or society, RCM continues. Verify the organiser's constitution before booking the entry, and raise a self-invoice where the provider is unregistered.

Question 14

What details must a GST tax invoice compulsorily contain?

Accepted Answer

Rule 46 of the CGST Rules prescribes the mandatory contents: your name, address and GSTIN; a consecutive serial number not exceeding sixteen characters, unique for the financial year; the date of issue; the recipient's name, address and GSTIN if registered; the HSN or SAC code; description, quantity and unit; total and taxable value; any discount; the rate and amount of CGST, SGST or IGST shown separately; place of supply with the state name for inter-state supplies; a declaration where tax is payable on reverse charge; and signature or digital signature of the supplier. Missing fields make the invoice defective and can jeopardise your buyer's credit.

Question 15

Can one invoice contain items taxed at different GST rates?

Accepted Answer

Yes, there is no requirement to issue separate invoices per rate. A single tax invoice can carry multiple line items, each with its own HSN code, taxable value, rate and tax amount, and the totals section simply aggregates the tax rate-wise. A hardware store in St. Thomas Mount can bill cement at 18 percent and certain tools at 5 percent on one document. What matters is that each line is classified and taxed correctly, and that mixed baskets are not collapsed into one rate. Be careful with genuine composite supplies, where one principal supply drives a single rate; that is a classification question, not an invoicing one.

Question 16

Something is malfunctioning on the GST portal. How do I raise a formal grievance ticket?

Accepted Answer

Use the GST Self-Service Grievance Redressal Portal at selfservice.gstsystem.in. Select Report Issue, type a keyword describing the problem, and the system suggests the matching category along with FAQs; if those do not resolve it, proceed to raise the ticket by entering your GSTIN or ARN, contact details and a description, and attach screenshots of the error. A ticket reference number is issued instantly by email and SMS. Raising a ticket also creates a record that the failure was on the system side, which helps later if a deadline was missed because of a portal outage. Our St. Thomas Mount office logs tickets for clients as part of retainer support.

Question 17

By when must I issue a tax invoice when I sell goods?

Accepted Answer

For goods, Section 31 requires the tax invoice to be issued before or at the time of removal of the goods, where the supply involves movement, or before or at the time of delivery or making the goods available in other cases. In simple terms, the invoice must travel with the goods; a lorry leaving your St. Thomas Mount godown without an invoice is exposed to detention even if the e-way bill exists. For continuous supplies of goods with successive statements or payments, the invoice must be issued when each statement is issued or each payment is received.

Question 18

What GST rate applies to cars and two-wheelers now?

Accepted Answer

Small cars, meaning petrol cars up to 1200cc and diesel cars up to 1500cc with length not exceeding 4 metres, attract 18 percent GST, down sharply from the earlier 28 percent plus cess. Larger cars, SUVs above these specifications, attract the 40 percent rate, but with the compensation cess gone, the overall burden on most of them is still lower than before. Motorcycles up to 350cc are at 18 percent, while those above 350cc attract 40 percent. Electric vehicles continue at a concessional 5 percent. Dealers must also apply these rates to demo vehicle sales.

Question 19

How much does GSTR-1 & GSTR-3B monthly filing cost in St. Thomas Mount?

Accepted Answer

Our fee for GSTR-1 & GSTR-3B monthly filing in St. Thomas Mount starts at Rs.749/month and is quoted in full before we begin — there are no hidden charges added later. The fee covers professional work end to end: document review, preparation, filing and follow-up until completion. Government fees or portal charges, where applicable, are separate and always shown to you upfront. For an exact quote based on your turnover and business type, call +91 - 9600 606 444 and a consultant will confirm it on the call.

Question 20

Do you provide gst return filing for small businesses and proprietorships in St. Thomas Mount?

Accepted Answer

Yes. A large share of our clients in St. Thomas Mount are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.749/month and the process are the same regardless of size, and we explain the compliance position in plain language — in Tamil or English — so you understand what is being filed on your behalf and why.

Question 21

What is the process for GSTR-1 & GSTR-3B monthly filing?

Accepted Answer

The process runs in clear stages: Monthly data collection; GSTR-1 preparation and filing; ITC reconciliation with GSTR-2B; Tax computation and confirmation. A senior consultant reviews your file at each stage rather than passing it to a data-entry desk, and you receive a confirmation with the filed documents once it is complete. You always know which stage your work is at — we update you on WhatsApp instead of leaving you to follow up.

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
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.
