Question 1

What documents are required for e-invoice setup in T. Nagar?

Accepted Answer

For e-invoice setup you will generally need: GST portal login credentials, Turnover figures for financial years from 2017-18 onwards, Details of the billing or accounting software currently in use, Sample sales invoice with current format, HSN codes and rate list of goods or services supplied. The exact list depends on your constitution — proprietorship, partnership, LLP or company — and on the specifics of your case. Send what you have on WhatsApp to +91 - 9600 606 444 and we will confirm within the same working day exactly what else is needed, so nothing is rejected later for a missing paper.

Question 2

Is there a GST consultant near T. Nagar for e invoice registration?

Accepted Answer

Yes. We serve T. Nagar and the surrounding areas from our office at Porur, Chennai - 600 116, Tamil Nadu, and most e-invoice setup work is completed online — you send documents on WhatsApp and we handle the portal work. If you prefer in-person help, we offer doorstep document pickup across T. Nagar and you are welcome to visit our office. Reach us on +91 - 9600 606 444 between 9 AM and 8 PM, Monday to Saturday.

Question 3

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 4

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 T. Nagar facing frequent cancellations usually need billing process fixes; call +91 - 9600 606 444 for help streamlining it.

Question 5

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 T. Nagar 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 6

What exactly are the IRN and QR code on an e-invoice?

Accepted Answer

When you report an invoice to the Invoice Registration Portal, it validates the data and returns a unique 64-character Invoice Reference Number, which is a hash generated from your GSTIN, the document number and the financial year, along with a digitally signed QR code. The QR code embeds key details such as both GSTINs, invoice number and date, taxable value and the IRN, allowing anyone to verify the invoice offline. A B2B invoice issued by a mandated taxpayer without an IRN is not a valid tax invoice, and the printed copy must carry the QR code.

Question 7

How do I register on the Invoice Registration Portal and set up e-invoicing?

Accepted Answer

Registration is done on the e-invoice portal einvoice1.gst.gov.in using your GSTIN; the system verifies you through an OTP sent to your GST-registered mobile and email, after which you create IRP login credentials. Businesses already registered on the e-way bill portal can use the same credentials. You then choose how invoices will be reported: direct portal entry, the free offline utility, or API integration through your accounting software such as Tally or a GSP. ChennaiGST handles the complete setup including software configuration and staff training for businesses in T. Nagar for Rs.1,999; call +91 - 9600 606 444 to schedule 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 T. Nagar businesses design clean series structures; call +91 - 9600 606 444.

Question 9

I sell online courses from T. Nagar. Does GST treat live classes and recorded courses differently?

Accepted Answer

The rate is 18 percent either way for commercial training, but the classification can differ. Fully automated recorded courses delivered online with minimal human involvement can fall within OIDAR services, which matters for cross-border sales because OIDAR has its own place of supply and registration consequences. Live, trainer-led online classes are ordinary services. Sales to learners outside India can qualify as export of services under an LUT if the payment and recipient conditions are met, while sales to Indian learners are taxable domestically. Since platforms, payment gateways and learner locations vary, we map each channel separately for T. Nagar course creators. Call +91 - 9600 606 444 for a session.

Question 10

Is a monthly ITC reconciliation service worth it for a small business near me in T. Nagar?

Accepted Answer

For most businesses claiming more than a lakh of ITC a month, yes. A monthly reconciliation matches every purchase invoice in your books against GSTR-2B, flags suppliers who have not filed, identifies blocked credits under Section 17(5), tracks the 180-day payment rule and produces a vendor follow-up list before the GSTR-3B due date of the 20th. The cost is typically far below the value of a single missed or disputed credit. ChennaiGST offers monthly reconciliation for businesses in T. Nagar starting at Rs.1,999, including vendor reminder emails. Call +91 - 9600 606 444 for a sample reconciliation of your latest month.

Question 11

Can a jeweller resell old jewellery under the margin scheme and pay GST only on the profit?

Accepted Answer

Yes, with an important condition. Under Rule 32(5), a dealer in second-hand goods who sells used jewellery as it is, or after minor processing such as cleaning and polishing that does not change its nature, can pay GST on the margin, the difference between selling and purchase price, with no tax if the margin is negative. The concession is lost the moment you melt the old jewellery and manufacture a new ornament, because the goods change form; the new piece is then taxed at 3% on full value. Maintain separate stock registers for as-is resale and melting lots to protect the margin claim.

Question 12

What is the GST rate on a works contract for a commercial building?

Accepted Answer

Under GST, a works contract relating to immovable property is treated wholly as a supply of services, and the standard rate is 18 percent on the contract value, with the contractor eligible for input tax credit on cement, steel and other inputs. This applies to construction, fabrication, erection, repair and renovation contracts for factories, offices and commercial buildings. The old VAT-plus-service-tax splitting of material and labour is gone; one rate applies to the whole consideration. Contractors should also note that free-issue materials supplied by the client can affect valuation, so contract drafting deserves attention before quoting.

Question 13

How do I decide whether to charge CGST plus SGST or IGST on an invoice?

Accepted Answer

Compare two data points: the location of the supplier and the place of supply determined under the IGST Act. If both fall in the same state, the supply is intra-state and you charge CGST plus SGST; if they fall in different states, it is inter-state and you charge IGST. The buyer's billing address alone is not the test; the place of supply rules for the specific goods or service govern. Common traps include hotel stays, property-linked services and bill-to ship-to chains, where the place of supply departs from the customer's address. Configuring these rules in your billing software saves T. Nagar businesses repeated corrections; call +91 - 9600 606 444 for a setup review.

Question 14

If I open a bulk bag and sell rice loose by weight, is that sale taxable?

Accepted Answer

No. The 5% levy on specified food items applies only when they are supplied in pre-packaged and labelled form in packs up to 25 kilograms. When a retailer opens bulk stock and weighs out loose quantities against each customer's order, the supply is not of a pre-packaged commodity, so it remains exempt. What you cannot do is sell an intact labelled retail pack and bill it as loose. Keep purchase records showing bulk procurement and maintain the loose counter separately from the packed shelf, because officers test this distinction during inspections of grocery businesses. When in doubt on a product, call +91 - 9600 606 444.

Question 15

We pay for foreign software subscriptions and overseas consultants. Is GST payable in India?

Accepted Answer

Yes. Import of services, meaning services from a supplier located outside India received by a person in India for business, attracts IGST under reverse charge in the recipient's hands, payable in cash and claimable as ITC if eligible. This catches cloud software, foreign professional fees, overseas advertising and licence fees. Two nuances matter: services from a related foreign party, such as your parent company, are taxable even without consideration under Schedule I, and OIDAR services supplied to unregistered consumers are taxed in the foreign supplier's own hands, not under RCM. Startups and IT firms in T. Nagar paying by card frequently miss these entries; reconcile foreign remittances against RCM paid annually.

Question 16

How do I round off tax amounts on a GST invoice?

Accepted Answer

Section 170 of the CGST Act prescribes normal rounding to the nearest rupee: where the tax contains a part of a rupee, fifty paise or more is rounded up to one rupee, and less than fifty paise is ignored. The rounding is applied to the tax amount on each invoice, separately for each tax head, so CGST and SGST are each rounded individually rather than rounding only the invoice total. Most billing software handles this automatically, but spreadsheets and manual bills often round the grand total instead, creating one-rupee mismatches that clutter reconciliations across thousands of invoices.

Question 17

What happened to the old 12 percent and 28 percent GST slabs?

Accepted Answer

Both slabs were abolished with effect from 22 September 2025. Nearly all goods that were at 12 percent moved down to 5 percent, and the bulk of the 28 percent items moved to 18 percent, with only a small set of luxury and demerit goods shifted up to the special 40 percent rate. This means old rate charts, printed price lists and software masters created before September 2025 are unreliable. Before quoting or billing, confirm the current rate against the CBIC rate notifications for your exact HSN code, or call +91 - 9600 606 444 and we will verify it for your product list.

Question 18

Which purchases commonly attract GST under reverse charge for a regular business?

Accepted Answer

Under Section 9(3), the recipient pays tax on notified supplies. The entries a typical business in T. Nagar encounters are: goods transport agency services, services of advocates and arbitral tribunals, sponsorship provided to companies and partnership firms, services of directors, security services from non-corporate providers, renting of passenger motor vehicles from non-corporate operators charging five percent, import of services, and renting of property from unregistered landlords in notified cases. Each month, scan your expense ledger for these heads, pay the tax in cash through GSTR-3B, and claim it back as ITC where eligible. Missed RCM is among the top audit findings; call +91 - 9600 606 444 for an RCM exposure review.

Question 19

Which GST office handles T. Nagar businesses?

Accepted Answer

Businesses in T. Nagar (PIN 600017) 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 20

Do you provide e invoice registration for small businesses and proprietorships in T. Nagar?

Accepted Answer

Yes. A large share of our clients in T. Nagar are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.1,999 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

How long does e-invoice setup take in T. Nagar?

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.

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
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.
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.
