Question 1

Which GST office handles Mugalivakkam businesses?

Accepted Answer

Businesses in Mugalivakkam (PIN 600116) 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

What is the process for new GST registration?

Accepted Answer

The process runs in clear stages: Document collection; Application preparation; Filing and Aadhaar authentication; Query handling. 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.

Question 3

I am a doctor running my own clinic. Do I need GST registration at all?

Accepted Answer

If your entire income consists of exempt healthcare services, no. Section 23 provides that a person engaged exclusively in supplying exempt goods or services is not liable to registration, irrespective of turnover, so a practitioner earning even Rs.1 crore purely from consultations and treatment need not register. The position changes the moment taxable income enters the same PAN, such as commercial property rent, pharmacy sales to outpatients, aesthetic procedures or paid webinars for a company; then the normal Rs.20 lakh aggregate threshold applies, counting the exempt receipts too. Many doctors in Mugalivakkam cross the line through rental income without noticing.

Question 4

Is Aadhaar authentication compulsory for GST registration?

Accepted Answer

Aadhaar authentication is not compulsory, but it is strongly recommended. When the promoter and authorised signatory complete Aadhaar OTP authentication, the application is processed on the fast track and deemed approval applies if the officer does not act within seven working days. Without Aadhaar authentication, the department treats the application as higher risk, physical verification of the business premises is usually ordered, and approval can take up to thirty days. Most applicants in Mugalivakkam finish the OTP step in minutes, so there is rarely a reason to skip it unless the Aadhaar-linked mobile number is inactive.

Question 5

I am a consultant in Mugalivakkam with clients in Mumbai and Delhi. Does inter-state billing force GST registration?

Accepted Answer

Not for services. Although Section 24 makes registration compulsory for inter-state taxable supplies, Notification 10/2017-Integrated Tax specifically exempts persons making inter-state supplies of services from mandatory registration until aggregate turnover crosses Rs.20 lakh. So a freelancer or consultant in Mugalivakkam can bill clients anywhere in India without registering, as long as total turnover stays within the threshold. Note that this relief is only for services; inter-state supply of goods still requires registration from the first rupee. Once you do cross Rs.20 lakh, you must register within thirty days. Call +91 - 9600 606 444 to check your position.

Question 6

I sell only loose, unbranded grains and fresh vegetables. Do I need GST registration at all?

Accepted Answer

No. Under Section 23 of the CGST Act, a person engaged exclusively in supplying goods that are wholly exempt from tax is not liable to register, regardless of turnover. A trader in Mugalivakkam dealing only in loose cereals, pulses sold unpackaged, fresh fruits and vegetables therefore stays outside GST entirely. The position changes the day you add even one taxable line, such as pre-packaged branded packs, edible oil or packaged snacks; from then on the normal threshold rules apply to your aggregate turnover, which counts the exempt sales too. Review your product mix once a year, or call +91 - 9600 606 444 for a quick applicability check.

Question 7

I run two different businesses. Can both be under one GST number?

Accepted Answer

Yes, one GSTIN can cover multiple businesses of the same person within Tamil Nadu. You can show one location as the principal place of business and add the other as an additional place of business, and list multiple goods and services on the same registration. Remember that aggregate turnover for the threshold is computed by clubbing all businesses under the same PAN. Alternatively, GST law permits you to take separate registrations for separate places of business in the same state if you prefer independent billing and returns, though each GSTIN then carries its own full compliance calendar.

Question 8

Can I take GST registration using a virtual office address near me?

Accepted Answer

Yes, GST registration on a virtual office address is permitted provided you have valid documentation: an agreement with the virtual office provider, an NOC, and the provider's ownership proof such as an electricity bill. The premises must genuinely be accessible for departmental visits, and your name board and documents should be displayed there, because officers frequently conduct physical verification for virtual office applications. Choose a provider experienced with GST verifications, keep books or records accessible at the address, and respond promptly to any REG-03 query. We can advise on compliant virtual office setups in Mugalivakkam; call +91 - 9600 606 444 for guidance.

Question 9

In an exchange offer, a customer pays cash plus an old device. On what value do I charge GST?

Accepted Answer

On the full price of the new product before the exchange benefit. Where consideration is not wholly in money, Rule 27 of the valuation rules requires tax on the open market value of the supply, which in retail practice is the sticker price of the new phone or appliance; the old device taken in is part consideration, not a discount. Charging GST only on the net cash collected understates turnover and is a classic audit finding in electronics retail. Show the exchange value as a separate adjustment line after tax. Retailers running festival exchange melas should get invoice formats vetted; call +91 - 9600 606 444.

Question 10

How is interest calculated if I pay GST late?

Accepted Answer

Interest is charged at 18 percent per annum under Section 50 of the CGST Act, calculated day-wise from the due date until the date of payment. Following the amendment to Section 50, interest on delayed GSTR-3B filing applies only on the portion of tax paid through the electronic cash ledger, not on the amount settled using input tax credit. For example, a cash liability of Rs.1,00,000 paid 30 days late attracts roughly Rs.1,479 as interest. We compute this precisely before filing so clients in Mugalivakkam never overpay or underpay.

Question 11

When is GSTR-1 due for my business in Mugalivakkam?

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 Mugalivakkam tracks these dates for every client so nothing slips. Call +91 - 9600 606 444 if you need a filing reminder set up.

Question 12

Our company paid fees to a lawyer. Who pays the GST on this?

Accepted Answer

You do, as the recipient. Legal services supplied by an individual advocate, a firm of advocates or a senior advocate to a business entity are notified under Section 9(3), so the advocate does not charge GST and your business pays 18 percent under reverse charge in cash through GSTR-3B, claiming it back as ITC if otherwise eligible. Relief exists for small recipients: legal services to a business entity whose turnover is within the registration threshold are exempt. Since the advocate is usually unregistered, remember to raise a self-invoice and payment voucher for the transaction. Litigation-heavy businesses in Mugalivakkam should reconcile their legal expense ledger against RCM paid every quarter.

Question 13

What are the most common mistakes Chennai businesses make with GST refunds and ITC?

Accepted Answer

The recurring ones we see across Mugalivakkam are: missing the two-year limitation for RFD-01, mismatches between GSTR-1, GSTR-3B and shipping bill data that stall export refunds, forgetting the April LUT renewal, claiming ITC on invoices absent from GSTR-2B, ignoring blocked credits under Section 17(5), breaching the 180-day supplier payment rule, and treating deficiency memos as rejections instead of refiling within limitation. Each of these is preventable with a simple monthly checklist and a year-end reconciliation. ChennaiGST builds exactly this discipline into its retainer engagements; call +91 - 9600 606 444 if any of these sounds familiar.

Question 14

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 15

My customer in Mumbai asked me to deliver goods directly to his buyer in Mugalivakkam. 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 Mugalivakkam. 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 16

Can I transfer cash ledger balance from one GSTIN to another GSTIN of the same PAN?

Accepted Answer

Yes, within limits. Under Section 49(10), unutilised IGST and CGST balances in the electronic cash ledger can be transferred through PMT-09 to the cash ledger of a distinct person, that is, another GSTIN registered on the same PAN in the same or another state. SGST balances cannot be moved across states in this manner. The transfer is not permitted if the transferring GSTIN has any unpaid liability standing in its electronic liability register. Multi-state businesses headquartered in Mugalivakkam use this to shift idle deposits to the branch that actually needs the cash, avoiding fresh working capital outflow.

Question 17

Our head office in Mugalivakkam supports branches in other states. Is a cross-charge invoice really required?

Accepted Answer

Yes. Branches with separate GSTINs are distinct persons, and Schedule I treats supplies between them as taxable even without consideration. Services your head office renders to branches, such as accounting, IT support or management oversight, should be cross-charged through a tax invoice with IGST, which the branch claims as credit. On valuation, Rule 28 helps: where the recipient branch is entitled to full ITC, the value declared on the invoice is deemed to be the open market value, and Circular 199/11/2023 clarifies that internally generated services need not include the salary cost of head office employees. A documented cross-charge policy keeps audits short; call +91 - 9600 606 444 to set one up.

Question 18

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 19

How much does new GST registration cost in Mugalivakkam?

Accepted Answer

Our fee for new GST registration in Mugalivakkam starts at Rs.1,499 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 new gst registration for small businesses and proprietorships in Mugalivakkam?

Accepted Answer

Yes. A large share of our clients in Mugalivakkam are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.1,499 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

Do you provide new GST registration for businesses on Perumal Kovil Street?

Accepted Answer

Document pickup can be arranged at your premises, or you can send everything on WhatsApp and complete GST registration without leaving your counter. Call +91 - 9600 606 444 and mention your location; a consultant will confirm the fee and timeline immediately.

Aspect	With ChennaiGST	DIY / Unattended
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.
Risk of notices	GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices.	Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice.
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.
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.
Portal credentials and data	Logins handled by a small engaged team under strict confidentiality, with credentials stored securely and never passed onward.	Passwords circulating on chats with freelancers and part-timers, and no accountability for who has accessed your business data.
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.
