Question 1

Which GST office handles Sembakkam businesses?

Accepted Answer

Businesses in Sembakkam (PIN 600073) 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 2

Are there any hidden charges for registration amendment REG-14?

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.

Question 3

I opened a godown in Sembakkam. Should I add it to my GST registration?

Accepted Answer

Yes, every warehouse, godown, branch or shop in Tamil Nadu from which you operate must be declared on your registration as an additional place of business. File a core field amendment in Form REG-14, add the godown address with supporting proof such as the rent agreement and owner's electricity bill, and submit; officer approval usually takes about fifteen working days. Declaring the godown matters practically: e-way bills can show it as a dispatch point, stock kept there is properly accounted, and you avoid penalties if officers inspect undeclared premises. Our Sembakkam team files these amendments regularly; call +91 - 9600 606 444.

Question 4

I am converting my proprietorship in Sembakkam into a private limited company. Can I amend my GST?

Accepted Answer

No, this cannot be done by amendment. A change in constitution that results in a new PAN, such as proprietorship to partnership or company, requires a fresh GST registration in the new entity's name and PAN. The practical sequence is: incorporate the company, obtain its new GSTIN, transfer stock and unutilised input tax credit from the old registration to the new one using Form ITC-02, and then cancel the proprietorship's registration citing change in constitution, followed by its final return GSTR-10 within three months. We manage this full transition for Sembakkam businesses; call +91 - 9600 606 444 to plan the sequence correctly.

Question 5

Can I add or change the trade name on my GST certificate without a new registration?

Accepted Answer

Yes. The trade name is a core field, so you file an amendment in Form REG-14 selecting Business Details, enter the new trade name, and give the reason and date of change. Officer approval typically comes within about fifteen working days, after which the updated certificate reflecting the new trade name can be downloaded. Your GSTIN does not change because it is linked to your PAN. This is useful when a proprietor starts branding the shop differently from their own name. Remember to update the new trade name on invoices, your name board and bank records once approved.

Question 6

How do I update the mobile number and email registered on the GST portal?

Accepted Answer

If the mobile and email belong to the authorised signatory, log in, go to Amendment of Registration Non-Core Fields, select the authorised signatory tab, enter the new contact details, and verify them with OTPs sent to the new number and email. Non-core amendments take effect without officer approval, so the change is quick. If the person who was authorised signatory has left the business, you may first need to add a new authorised signatory, or approach the jurisdictional officer if you have lost access entirely. Keeping these credentials current is important because all notices and OTPs flow to them.

Question 7

Where exactly on the GST portal do I file a core field amendment, and what happens after submission?

Accepted Answer

Log in and go to Services, then Registration, then Amendment of Registration Core Fields. The editable tabs cover business details, principal place of business, additional places and promoter or partner details; open the relevant tab, make the change, and enter the reason and date of amendment in the boxes provided, attaching supporting documents within the portal's size limits. Move to the Verification tab, select the authorised signatory and place, and submit with DSC or EVC. An ARN is generated, the application lands in your jurisdictional officer's queue, and its progress is visible under Track Application Status until approval.

Question 8

How do I add a new authorised signatory to my GST registration?

Accepted Answer

Adding or changing an authorised signatory is a non-core amendment, so it needs no officer approval. Log in, go to Services, then Registration, then Amendment of Registration Non-Core Fields, and open the Authorised Signatory tab. Click Add New, enter the person's name, PAN, Aadhaar, mobile, email and photograph, upload the authorisation letter or board resolution, and submit with DSC or EVC. The new signatory's mobile and email are verified by OTP. Businesses in Sembakkam should do this the moment an accountant or director handling GST changes, because every notice alert and filing OTP flows to the signatory on record.

Question 9

I billed customers while my GST registration was being processed. What is a revised invoice?

Accepted Answer

Registration takes effect from the date you became liable, but your GSTIN arrives only when the certificate is issued. For supplies made between the effective date of registration and the date the certificate was granted, Rule 53 allows you to issue revised invoices against the original bills, within one month from the date of issuance of the certificate. The revised invoice carries your GSTIN, is marked as a revised invoice, and references the original invoice number and date. This lets your registered buyers in Sembakkam claim input credit for that interim period. A consolidated revised invoice is permitted for unregistered buyers within a state.

Question 10

My shop in Sembakkam is on rent. What address proof do I upload for GST?

Accepted Answer

For rented premises, upload the registered or notarised rent agreement in the name of the business or proprietor, along with a document proving the landlord's ownership, such as a recent electricity bill or property tax receipt for the same address. If the rent agreement is not available, a consent letter or No Objection Certificate from the owner together with their ownership proof is accepted. Ensure the address on the agreement matches the address entered in REG-01 exactly, including door number and pin code, because mismatches are the most common reason officers issue REG-03 clarification notices.

Question 11

I supply cement and steel on credit to local builders. What GST care do such B2B sales need?

Accepted Answer

Three things matter. First, issue proper B2B tax invoices with the builder's GSTIN and correct HSN codes, because your GSTR-1 feeds their credit claims and errors invite immediate calls. Second, watch consignment values, since movements above the e-way bill limits need bills generated before dispatch, and construction material loads cross the threshold easily. Third, monitor receivables: if a builder does not pay you, your own output tax has still been paid, and conversely builders who delay paying you beyond 180 days must reverse their credit, which often prompts them to settle. Hardware dealers in Sembakkam can call +91 - 9600 606 444 for a receivables-linked compliance routine.

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

Is GST payable under reverse charge on payments made to our company directors?

Accepted Answer

It depends on the capacity in which the director is paid. CBIC Circular 140/10/2020 settles the position: remuneration to a whole-time or executive director who is an employee, paid as salary with TDS under Section 192, is outside GST entirely as an employer-employee transaction. In contrast, sitting fees, commission and professional charges paid to independent or non-executive directors, typically suffering TDS under Section 194J, are taxable and the company pays 18 percent under reverse charge, claiming ITC. Companies in Sembakkam should split their director payments ledger accordingly, issue self-invoices for the RCM portion, and keep board resolutions and TDS treatment consistent as supporting evidence.

Question 14

Our small lodge in Sembakkam gets bookings through online travel apps. Who pays the GST?

Accepted Answer

It depends on your registration status. If the lodge is registered, you charge GST on the accommodation and the platform collects TCS on payments routed through it, which you claim back on the portal. If the lodge is not liable to be registered, the law shifts the liability to the e-commerce operator itself under Section 9(5), so the app pays the tax on accommodation booked through it and the small lodge need not register merely because it lists online. Direct walk-in business remains within your threshold computation. Keep the platform agreements and statements, since they determine who reported the tax.

Question 15

What are the rules for numbering GST invoices?

Accepted Answer

The invoice serial number must be consecutive, must not exceed sixteen characters, and may contain alphabets, numerals and the special characters hyphen and slash, in one or multiple series. Each number must be unique for a financial year, so most businesses restart their series every April with a year prefix such as 2026-27/001. Gaps in a series invite questions during audit because officers may suspect unreported invoices, and cancelled invoice numbers should be retained in records with the cancelled copy. The document series you use must also be declared in Table 13 of GSTR-1 each period.

Question 16

Is GST still charged on health insurance premiums?

Accepted Answer

Not on individual policies. With effect from 22 September 2025, premiums on all individual life insurance policies and individual health insurance policies, including family floater and senior citizen plans, are exempt from GST, along with their reinsurance. Earlier these attracted 18 percent, so the change directly reduces the premium outgo for households. Group policies taken by businesses for employees continue to be taxable, and the input tax credit position on such group covers still depends on whether the cover is statutorily obligatory. When renewing policies, check that the insurer has passed on the exemption rather than merely repricing the premium.

Question 17

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 Sembakkam 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 18

Is there really a penalty for not displaying my GST number at my shop?

Accepted Answer

Yes. Rule 18 of the CGST Rules requires every registered person to display the registration certificate in a prominent location at the principal place of business and every additional place, and to display the GSTIN on the name board at the entry of each such premises. There is no separate penalty provision for this lapse, so officers invoke the general penalty under Section 125, which can extend to Rs.25,000 under CGST with a matching state penalty. Inspection teams visiting Sembakkam markets routinely check name boards first, so a few hundred rupees of signage is the cheapest compliance in the entire GST law.

Question 19

How much does registration amendment REG-14 cost in Sembakkam?

Accepted Answer

Our fee for registration amendment REG-14 in Sembakkam starts at Rs.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

How long does registration amendment REG-14 take in Sembakkam?

Accepted Answer

Core field approval in about 15 days; non-core immediate. 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 21

What documents are required for registration amendment REG-14 in Sembakkam?

Accepted Answer

For registration amendment REG-14 you will generally need: GST portal login credentials, Current registration certificate REG-06, New address proof such as electricity bill or property tax receipt, for address changes, Rent agreement and owner NOC, if the new premises are rented, Amended partnership deed or board resolution, for constitution changes. 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.

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