Question 1

What is the process for GSTR-1 & GSTR-3B monthly filing?

Accepted Answer

The process runs in clear stages: Monthly data collection; GSTR-1 preparation and filing; ITC reconciliation with GSTR-2B; Tax computation and confirmation. 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 2

Which GST office handles Mangadu businesses?

Accepted Answer

Businesses in Mangadu (PIN 600122) 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

Can I issue a single credit note against several invoices?

Accepted Answer

Yes. Since the amendment to Section 34 by the CGST (Amendment) Act, 2018, effective 1 February 2019, the law permits one or more credit notes to be issued against one or more tax invoices of a financial year. A distributor giving a season-end adjustment to a retailer can therefore issue one consolidated credit note covering dozens of invoices, rather than one note per bill. When reporting it in GSTR-1, the portal accepts credit notes without invoice-wise linking for this reason. Maintain a working annexed to the credit note listing the invoices covered, because in scrutiny the officer will ask you to establish the linkage and the arithmetic.

Question 4

A client paid me an advance. Do I raise an invoice or something else?

Accepted Answer

On receiving an advance, you issue a receipt voucher under Rule 50, not an invoice; the tax invoice follows when the service is actually supplied. GST is payable on advances received for services in the period of receipt, and the receipt voucher documents that liability. Advances for the supply of goods are not taxed at receipt for normal taxpayers under Notification 66/2017. If the rate is not determinable when the advance arrives, tax is paid at 18 percent, and if the nature of supply is not determinable, it is treated as inter-state. Service firms in Mangadu with retainer billing should map this into their monthly cycle.

Question 5

We hire security guards from an agency. Should they charge GST or should we pay it ourselves?

Accepted Answer

Check the agency's constitution. Since 1 January 2019, security services by way of supply of security personnel provided by any person other than a body corporate to a registered person fall under reverse charge, so your business pays the 18 percent directly and claims credit. If the agency is a body corporate, such as a private limited company, it charges GST under forward charge on its invoice. Recipients registered under the composition scheme are excluded from this reverse charge entry. Businesses in Mangadu commonly pay agencies' forward-charge invoices while also missing their own RCM cases, so an annual review of security and manpower bills is worthwhile.

Question 6

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 7

I generate e-invoices. Do I still have to prepare GSTR-1 separately?

Accepted Answer

If your aggregate turnover exceeds Rs.5 crore, e-invoicing is mandatory and the invoice details reported to the Invoice Registration Portal auto-populate into your GSTR-1. However, auto-population is not a substitute for review. B2C sales, exports without IRN issues, credit notes, amendments and advances still need to be verified or added manually before submission. We review the auto-drafted GSTR-1 against your books each month so that what is filed matches your accounts exactly. If you have just crossed the Rs.5 crore threshold, call +91 - 9600 606 444 and we will set up e-invoicing correctly.

Question 8

How does a GTA opt for forward charge, and by when must it be done?

Accepted Answer

The option is exercised by filing the Annexure V declaration on the GST portal. For an existing GTA, the window for a financial year runs from 1 January to 31 March of the preceding financial year, so the choice for the coming year must be locked in by 31 March. A newly registered GTA must file the declaration within forty-five days of applying for registration or one month from the date of obtaining registration, whichever is later. Once exercised, the option continues for future years automatically unless the GTA files Annexure VI to revert to reverse charge. Missing the window means remaining under the default reverse charge mechanism for the whole year.

Question 9

Our company spends on CSR activities. Is the GST paid on those purchases creditable?

Accepted Answer

Not any more. Section 17(5)(fa), inserted with effect from 1 October 2023, specifically blocks input tax credit on goods or services used for corporate social responsibility activities under Section 135 of the Companies Act. Before this date the position was contested, with advance rulings going both ways, so credits availed for earlier periods may still be defensible on merits if questioned. For current periods, GST on CSR purchases, whether school furniture donated or medical supplies distributed, is a cost. Companies in Mangadu should route CSR procurement through a separate expense code so their monthly reconciliation automatically excludes these invoices from the ITC claim.

Question 10

My supplier filed GSTR-1 but never filed GSTR-3B. Does that affect my credit?

Accepted Answer

Yes, through Rule 37A. If your supplier reports the invoice in GSTR-1, the credit flows into your GSTR-2B and you may claim it, but if that supplier has not filed the GSTR-3B for the same period by 30 September following the end of the financial year, you must reverse the credit in a return filed on or before 30 November. Reversal done within this window carries no interest; delay beyond it attracts interest at 18 percent. The credit can be re-availed once the supplier eventually files GSTR-3B. A supplier filing-status check is therefore now part of any serious reconciliation for businesses in Mangadu.

Question 11

How do I pay tax monthly under QRMP if the return is only quarterly?

Accepted Answer

For the first two months of each quarter, tax is deposited through challan PMT-06 by the 25th of the following month. You can use the fixed sum method, paying 35 percent of the tax paid in cash in the previous quarter (or 100 percent of the tax paid in cash in the last month of the previous quarter if you were a monthly filer), or the self-assessment method, paying actual liability after adjusting input tax credit. The third month's tax is settled in the quarterly GSTR-3B itself. We compute the safer option for each client in Mangadu every month.

Question 12

We hire cabs monthly for employee transport in Mangadu. 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 13

Which everyday goods now attract 5 percent GST?

Accepted Answer

The 5 percent slab now covers most household essentials that earlier fell in the 12 or 18 percent brackets: soaps, shampoos, toothpaste and toothbrushes, hair oil, bicycles, kitchen utensils and tableware. Packaged foods such as butter, ghee, cheese, namkeens, sauces, pasta, biscuits and chocolates are also at 5 percent, as are most medicines, medical devices and agricultural machinery. Apparel and footwear priced up to Rs.2,500 per piece attract 5 percent as well. Retailers in Mangadu should update billing software rate masters item by item rather than assuming old rates continue.

Question 14

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 Mangadu paying by card frequently miss these entries; reconcile foreign remittances against RCM paid annually.

Question 15

Where is the place of supply for services connected to a building or land?

Accepted Answer

Services directly relating to immovable property, including those of architects, interior decorators, engineers, surveyors, construction and works contract services, renting, and accommodation in hotels, are supplied where the property is located, under Section 12(3). The recipient's location and registration are irrelevant. So a Mangadu architect designing a factory in Coimbatore charges CGST plus SGST of Tamil Nadu, but for a project in Kochi the place of supply is Kerala and IGST applies. For hotels, the state where the hotel stands is always the place of supply, which is why accommodation is invariably billed with that state's local taxes regardless of where the guest's business is registered.

Question 16

My customer says he cannot claim ITC because of my late filing. Is that correct?

Accepted Answer

Yes, he is right. A buyer can claim input tax credit only for invoices appearing in his GSTR-2B, which is generated from suppliers' GSTR-1 and IFF filings. If you file GSTR-1 after the 11th, your invoices miss that month's GSTR-2B and your customer's credit gets pushed to the next month, straining his working capital. Repeated delays lead buyers to withhold the GST portion of payments or move to more compliant vendors. Timely GSTR-1 filing is therefore a commercial necessity, not just a legal one. ChennaiGST ensures clients in Mangadu never face this complaint.

Question 17

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 Mangadu businesses repeated corrections; call +91 - 9600 606 444 for a setup review.

Question 18

Something is malfunctioning on the GST portal. How do I raise a formal grievance ticket?

Accepted Answer

Use the GST Self-Service Grievance Redressal Portal at selfservice.gstsystem.in. Select Report Issue, type a keyword describing the problem, and the system suggests the matching category along with FAQs; if those do not resolve it, proceed to raise the ticket by entering your GSTIN or ARN, contact details and a description, and attach screenshots of the error. A ticket reference number is issued instantly by email and SMS. Raising a ticket also creates a record that the failure was on the system side, which helps later if a deadline was missed because of a portal outage. Our Mangadu office logs tickets for clients as part of retainer support.

Question 19

Accepted Answer

Question 20

Accepted Answer

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
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.
