Question 1

How long does e-invoice setup take in Tambaram?

Accepted Answer

1-2 working days. That assumes your documents are complete and there is no departmental query. We start the same day we receive your papers and tell you the realistic completion date upfront rather than an optimistic one. Where the GST portal or the officer causes delay — clarifications, physical verification or system issues — we track it daily and keep you informed on WhatsApp.

Question 2

Which GST office handles Tambaram businesses?

Accepted Answer

Businesses in Tambaram (PIN 600045) generally fall under the CGST Chennai Outer 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 3

Do I need to generate e-invoices for my retail B2C sales too?

Accepted Answer

No. The e-invoice mandate covers B2B supplies, supplies to SEZs, exports and credit or debit notes for such transactions. B2C invoices are not reported to the IRP at present. However, taxpayers with aggregate turnover above Rs.500 crore must print a dynamic QR code on B2C invoices to enable digital payment, which is a separate requirement from e-invoicing. So a retailer in Tambaram with Rs.8 crore turnover generates IRNs only for its B2B and export invoices while billing walk-in customers normally. Configuring your billing software to segregate the two flows avoids accidental non-compliance.

Question 4

What is the penalty if I am covered by e-invoicing but do not generate IRNs?

Accepted Answer

The consequences are serious. An invoice issued without an IRN by a mandated taxpayer is not a valid tax invoice, which exposes you to penalty under Section 122 of Rs.10,000 or the tax due, whichever is higher, per invoice for non-issuance, and Rs.25,000 per invoice for an incorrect invoice. Goods moving on such invoices can be detained, and, most damaging commercially, your B2B customers may lose their input tax credit and will quickly stop buying from you. Large buyers now routinely verify IRNs before releasing payments. If you have crossed Rs.5 crore and have not started, regularise immediately rather than waiting for a notice.

Question 5

Are any businesses exempt from e-invoicing even above Rs.5 crore turnover?

Accepted Answer

Yes. CBIC has exempted certain categories irrespective of turnover: banks, insurers and other financial institutions including NBFCs, goods transport agencies transporting goods by road, suppliers of passenger transportation services, admission to cinema exhibitions in multiplexes, SEZ units, and government departments and local authorities. Note that SEZ developers are covered by the mandate even though SEZ units are exempt. If you fall in an exempt category you should still verify vendor e-invoices you receive, because your ITC depends on their compliance. When in doubt about applicability, call +91 - 9600 606 444 for a quick assessment of your registrations.

Question 6

Is there a deadline for uploading invoices to the IRP after issuing them?

Accepted Answer

For taxpayers with aggregate annual turnover of Rs.10 crore and above, the IRP rejects invoices reported more than thirty days after the invoice date; this thirty-day window applies from 1 April 2025 and covers invoices as well as credit and debit notes. Smaller mandated taxpayers currently have no system-enforced limit, but best practice is to generate the IRN at the time of invoicing itself, since a B2B invoice without an IRN is not valid at all. Real-time generation through your accounting software removes this risk entirely, which is why integrated setup matters.

Question 7

I generated an e-invoice with a mistake. Can I cancel or correct it?

Accepted Answer

An IRN can be cancelled on the IRP within twenty-four hours of generation, provided a valid e-way bill is not active against it. After twenty-four hours, cancellation on the IRP is not possible; you must handle the correction through a credit note or debit note under Section 34, and any changes will also reflect when you file GSTR-1. Note that an e-invoice cannot be partially amended on the portal, and a cancelled invoice number cannot be reused for a fresh IRN. Businesses in Tambaram facing frequent cancellations usually need billing process fixes; call +91 - 9600 606 444 for help streamlining it.

Question 8

Can I run different invoice series for different branches or types of sales?

Accepted Answer

Yes. The rules expressly permit one or multiple series of invoice numbers, so you can run separate series for each branch, counter or category, for example RET/001 for retail billing and EXP/001 for exports, under the same GSTIN. Each series must independently be consecutive and unique within the financial year, and all series must be reported in the documents table of GSTR-1. For businesses under the e-invoicing mandate, the IRP validates that a document number is not repeated within the year for the GSTIN, so overlapping series will cause IRN rejections. We help Tambaram businesses design clean series structures; call +91 - 9600 606 444.

Question 9

How does ITC reversal work for capital goods used for both taxable and exempt supplies?

Accepted Answer

Rule 43 treats every commonly used capital good as having a useful life of five years, so its total credit is spread over sixty months for reversal purposes. Each month, one-sixtieth of the credit on all common capital goods is attributed to the period, and the exempt proportion, computed on the exempt-to-total turnover ratio, is reversed in GSTR-3B with applicable interest treatment. Capital goods used exclusively for taxable supplies need no reversal, while those used exclusively for exempt supplies get no credit at all. Keep a capital goods register with commissioning dates, because the sixty-month clock and any change in use must be tracked asset-wise.

Question 10

What happens if my goods are caught moving without a valid e-way bill?

Accepted Answer

The vehicle and goods can be detained under Section 129 of the CGST Act. Release requires payment of a penalty equal to two hundred percent of the tax payable on the goods where the owner comes forward, with harsher terms where ownership is not claimed; for exempted goods the penalty is two percent of the value up to Rs.25,000. The officer issues notices in the MOV series, and orders can be appealed in APL-01, currently with a twenty-five percent pre-deposit of the penalty for Section 129 cases. Prevention is far cheaper, so tighten dispatch checks or call +91 - 9600 606 444 if a vehicle in Tambaram is detained.

Question 11

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 12

What is the difference between ISD and cross-charge, and when is each used?

Accepted Answer

They solve different problems. The Input Service Distributor mechanism distributes credit on third-party input services received at the head office but consumed by branches, such as an audit fee or software licence billed centrally; the ISD passes the credit itself through ISD invoices and GSTR-6, without charging tax again. Cross-charge applies where the head office performs a service for branches using its own resources; here the head office makes an outward supply, issues a tax invoice with tax, and the branch claims ITC. With ISD distribution mandatory for common third-party input services from 1 April 2025, businesses must now run both mechanisms side by side, each for its correct category.

Question 13

What is the GST treatment for an event management company handling corporate events?

Accepted Answer

Event management services attract 18 percent with full input tax credit. Place of supply rules deserve attention: for organising an event for a registered client, the place of supply is the client's location, so a Chennai company organising a Goa offsite for a Bengaluru-registered client charges IGST to Karnataka. For unregistered clients, the place of supply is where the event is actually held. Admission tickets are taxed where the event takes place. Getting the state wrong means the client's credit is jeopardised and the tax may need repayment under the correct head, so event companies serving multi-state clients should map each contract before invoicing.

Question 14

What is the place of supply for freight and courier charges on goods?

Accepted Answer

For transportation of goods, including by courier, Section 12(8) fixes the place of supply as the location of the recipient where the recipient is registered. Where the recipient is unregistered, it is the location where the goods are handed over for transportation. So a registered Tambaram manufacturer paying a transporter for a Chennai-to-Delhi movement has Tamil Nadu as the place of supply, and the RCM liability is paid as CGST plus SGST if the transporter is also in Tamil Nadu. This rule matters chiefly for paying reverse charge on GTA freight under the correct heads, because paying IGST where CGST and SGST were due creates a refund-and-repay exercise later.

Question 15

What are the GST rates on gold, silver and diamond jewellery?

Accepted Answer

The special rates on precious metals were retained in the GST 2.0 restructuring. Gold, silver and articles of jewellery attract 3 percent GST, rough and unworked diamonds attract 0.25 percent, and jewellery making charges billed separately attract 5 percent. When a jeweller bills a customer, the metal value and making charges can appear as separate line items with their respective rates on the same tax invoice. Old gold purchased from an unregistered customer in exchange transactions does not attract GST in the customer's hands, but valuation of the net supply must be documented carefully.

Question 16

I declare income under Section 44ADA. Does that mean I am exempt from GST?

Accepted Answer

No, this is a common myth. Section 44ADA is a presumptive taxation scheme under the Income Tax Act that lets professionals declare fifty percent of gross receipts as income; it has nothing to do with GST. GST liability depends solely on aggregate turnover crossing the registration threshold and the nature of your supplies. In fact, the two departments now cross-match data, so gross receipts reported in your ITR and Form 26AS that exceed the GST turnover you declared are a known trigger for notices. Treat the two laws as parallel obligations, each with its own limits and filings.

Question 17

My customer in Mumbai asked me to deliver goods directly to his buyer in Tambaram. How do I bill this?

Accepted Answer

This is a bill-to ship-to transaction under Section 10(1)(b). When goods are delivered to a third party on the instruction of your customer, the law deems your customer's principal place of business as the place of supply, not the actual delivery point. So you invoice the Mumbai customer with IGST even though the goods physically moved within Tamil Nadu, and the Mumbai customer raises a second invoice on the ultimate recipient in Tambaram. Only one e-way bill is needed for the movement, generated by either party with both invoice legs captured. Wrongly billing the delivery-point state is a classic error that misplaces the credit chain entirely.

Question 18

Which educational services are actually exempt from GST?

Accepted Answer

The exemption is confined to an educational institution as defined, meaning one providing pre-school education, education up to higher secondary school or equivalent, education as part of a curriculum for obtaining a qualification recognised by Indian law, or an approved vocational education course. Services by such institutions to their students, and specified input services to schools such as transport, catering and security, are exempt. Everything outside this boundary is taxable: private tuition, test preparation, hobby classes, skill courses without recognised certification, and training by ed-tech companies. The recognition of the qualification under Indian law is the decisive test, not the subject taught.

Question 19

How much does e-invoice setup cost in Tambaram?

Accepted Answer

Our fee for e-invoice setup in Tambaram starts at Rs.1,999 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

Can I get e-invoice setup 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 Tambaram regularly complete e-invoice setup 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 21

Are there any hidden charges for e-invoice setup?

Accepted Answer

No. The fee quoted before we start is the fee you pay. Government fees, portal charges or statutory late fees, where they apply, are separate and disclosed to you in advance with the exact amount. We issue a proper GST invoice for our professional fee. If the scope of work changes — for example, an unexpected notice or additional periods — we tell you the revised fee before doing anything further.

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
