Question 1

Which GST office handles Old Pallavaram businesses?

Accepted Answer

Businesses in Old Pallavaram (PIN 600117) 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

How long does new GST registration take in Old Pallavaram?

Accepted Answer

3-7 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 3

Is PAN compulsory for GST? Do I need separate GSTINs for different states?

Accepted Answer

Yes, PAN is mandatory for normal GST registration; the GSTIN itself embeds your PAN in characters three to twelve, with the first two digits denoting the state, which is 33 for Tamil Nadu. Registration is state-wise, so if you have a fixed place of business in Tamil Nadu and another in Karnataka, you need a separate GSTIN in each state under the same PAN. Merely selling to customers in other states does not require registration there; it is having an establishment in that state that triggers it. Within Tamil Nadu, you may also take separate registrations for distinct places of business.

Question 4

How do I apply for a new GST registration for my business in Old Pallavaram?

Accepted Answer

GST registration is done online on the GST portal in two parts. In Part A of Form REG-01 you validate your PAN, mobile number and email to generate a Temporary Reference Number. In Part B you upload your business details, promoter details, principal place of business proof, bank details and photographs, then sign with EVC or DSC. On submission you receive an ARN to track status. If Aadhaar authentication succeeds and the application is complete, approval normally follows within about seven working days. Our team in Old Pallavaram handles the entire filing end to end; call +91 - 9600 606 444 to get started.

Question 5

My turnover just crossed the GST limit. How much time do I have to register?

Accepted Answer

You must apply for registration within thirty days of becoming liable, that is, within thirty days of the date your aggregate turnover crossed Rs.40 lakh for goods or Rs.20 lakh for services in Tamil Nadu. Registering late has consequences: tax becomes payable from the date liability arose, you cannot recover that GST from past customers, input credit for the unregistered gap is largely lost, and a penalty of Rs.10,000 or the tax evaded, whichever is higher, can apply. If your books show you crossed the limit recently, act now; our Old Pallavaram office can file within a day. Call +91 - 9600 606 444.

Question 6

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 Old Pallavaram claim input credit for that interim period. A consolidated revised invoice is permitted for unregistered buyers within a state.

Question 7

How many days does it take to get a GST number?

Accepted Answer

If you complete Aadhaar authentication and the officer raises no query, registration is generally approved within seven working days of submission. If you skip Aadhaar authentication, or the application is flagged for risk, the officer may direct physical verification of your premises and the timeline can extend up to thirty days. If the officer seeks clarification through Form REG-03, you must reply in Form REG-04 within seven working days, after which the application is either approved or rejected. Keeping documents clean and consistent with your PAN records is the single biggest factor in fast approval.

Question 8

My shop in Old Pallavaram 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 9

What is the difference between GSTR-1 and GSTR-3B?

Accepted Answer

GSTR-1 is a detailed invoice-wise statement of your sales, filed by the 11th of the next month. It does not involve any tax payment but it feeds your customers' GSTR-2B for input tax credit. GSTR-3B is a self-declared summary return, due on the 20th, where you report total sales, claim input tax credit and pay the net tax in cash or through credit. Both must match; mismatches between GSTR-1 and GSTR-3B are a common trigger for notices from the department, which is why we reconcile them before every filing.

Question 10

What returns does a composition dealer have to file and by when?

Accepted Answer

Composition taxpayers have just two recurring obligations. First, Form CMP-08, a quarterly statement of self-assessed tax, due by the 18th of the month following each quarter, so 18 July for the April to June quarter, 18 October, 18 January and 18 April for the rest. Second, the annual return GSTR-4, due by 30 June following the end of the financial year. There is no monthly GSTR-1 or GSTR-3B. Delays attract late fees and 18 percent interest on unpaid tax, and prolonged non-filing can lead to cancellation. Our Old Pallavaram office files CMP-08 for composition clients each quarter for Rs.1,499; call +91 - 9600 606 444.

Question 11

Why is the portal not letting me file GSTR-1?

Accepted Answer

Under Rule 59(6) of the CGST Rules, the portal blocks GSTR-1 filing if the GSTR-3B of the preceding tax period has not been filed. GST returns are sequential, so a single skipped GSTR-3B stops the entire chain. The fix is to file the pending GSTR-3B along with its late fee and interest, after which GSTR-1 opens up again. If you are unsure which period is pending, we can check your dashboard and clear the sequence for you the same day from our office near Old Pallavaram.

Question 12

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 13

Why is there GST on an under-construction flat but not on a ready-to-move one?

Accepted Answer

Construction of an apartment intended for sale is a supply of service only when any part of the consideration is received before the completion certificate is issued or before first occupation. Such under-construction sales attract 1 percent for affordable residential apartments and 5 percent for other residential apartments, both without input tax credit to the builder. Once the completion certificate is issued, sale of the building is neither a supply of goods nor of services under Schedule III, so a ready-to-move flat carries no GST at all, only stamp duty and registration charges. Timing of booking therefore changes the buyer's cost materially.

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

We hire cabs monthly for employee transport in Old Pallavaram. 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 16

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

Accepted Answer

The recurring ones we see across Old Pallavaram 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 17

What documents must I prepare for reverse charge purchases from unregistered suppliers?

Accepted Answer

Two documents are required. First, a self-invoice: Section 31(3)(f) obliges you to issue an invoice on yourself for goods or services received from an unregistered supplier on which you pay tax under reverse charge, and under Rule 47A this self-invoice must be issued within thirty days of receiving the supply. Second, a payment voucher under Rule 52 at the time of making payment to the supplier. The self-invoice is the document on which you claim the input tax credit of the reverse charge tax paid. Freight from unregistered transporters and advocate fees are typical cases where businesses miss this paperwork.

Question 18

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 19

Can I get new GST registration 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 Old Pallavaram regularly complete GST registration 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 20

Are there any hidden charges for new GST registration?

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 21

Do you provide new GST registration for businesses on Mariamman Koil Street?

Accepted Answer

Yes. We serve businesses on and around Mariamman Koil Street in Old Pallavaram — shops, offices, godowns and home-run businesses alike. 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
Annual return preparation	Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year.	Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly.
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.
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.
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.
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.
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.
