Question 1

Are there any hidden charges for GSTR-1 & GSTR-3B monthly filing?

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 2

Can I get GSTR-1 & GSTR-3B monthly filing 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 Adyar regularly complete monthly returns 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 3

Can my company claim ITC on GST paid to a contractor building our new office?

Accepted Answer

Generally no. Section 17(5) blocks input tax credit on works contract services and on goods or services used for construction of immovable property on your own account, even when the building is used for business. The exception is plant and machinery, so credit on GST paid for installing machinery, equipment or apparatus fixed to earth remains available. The block does not apply within the construction chain itself: a sub-contractor's works contract service supplied to the main contractor is creditable for the main contractor, since it is used for an onward works contract supply. Classifying civil costs correctly during a project saves disputes at audit.

Question 4

How are B2B and B2C invoices reported differently in GST returns?

Accepted Answer

B2B invoices, meaning supplies to registered buyers, are reported invoice by invoice in Table 4 of GSTR-1 with the buyer's GSTIN, so each one flows into that buyer's GSTR-2B for credit. B2C supplies are split into two streams: large inter-state invoices above the threshold are reported invoice-wise in Table 5, while all remaining B2C sales are reported as consolidated, rate-wise totals per state in Table 7. This is why capturing the buyer's GSTIN correctly at billing matters so much; an invoice keyed as B2C by a cashier gives the registered buyer no credit and triggers correction requests later.

Question 5

What happens if I miss filing GSTR-3B this month?

Accepted Answer

A late fee of Rs.50 per day (Rs.20 per day for a nil return) accrues automatically, capped based on your turnover, and interest at 18 percent per annum applies on tax paid late. You also cannot file the next period's GSTR-1 until the pending GSTR-3B is filed, since returns must be filed sequentially. If two consecutive tax periods remain unfiled, e-way bill generation gets blocked, and continued default can lead to suspension of your GSTIN. File the pending return at the earliest; call +91 - 9600 606 444 and we can clear the backlog quickly.

Question 6

My shop was closed for a month. Can I skip filing GST returns for that period?

Accepted Answer

No. Once you hold an active GSTIN, returns must be filed for every tax period regardless of business activity. If there were no sales and no purchases, you must file nil GSTR-1 and nil GSTR-3B for that month. Skipping creates a break in the sequential filing chain, blocks future returns, accumulates late fees and can eventually lead to suspension of registration. Nil returns take only minutes and can even be filed by SMS. If your business in Adyar has periods of inactivity, ask us about our low-cost nil filing plan.

Question 7

What is the difference between CPIN and CIN, and how long is a GST challan valid?

Accepted Answer

When you generate a challan in Form PMT-06 on the portal, the system issues a fourteen-digit Common Portal Identification Number, the CPIN, which identifies the unpaid challan and remains valid for fifteen days. Once the bank receives your payment, a seventeen-digit Challan Identification Number, the CIN, is generated, comprising the CPIN plus the bank code, and the amount credits your electronic cash ledger. If a challan expires unpaid, simply generate a fresh one; no consequence follows. Payment modes include net banking, UPI, cards, NEFT or RTGS, and over-the-counter deposit up to Rs.10,000 per challan per tax period.

Question 8

Our Adyar factory hires lorries through a transport agency. Who pays the GST?

Accepted Answer

Under the reverse charge entry, when a GTA that has not opted for forward charge provides service to specified recipients, the recipient pays the 5 percent tax. Specified recipients include factories, registered persons, body corporates, partnership firms including AOPs, co-operative societies and casual taxable persons. Your factory therefore pays 5 percent in cash through GSTR-3B, reports it in the reverse charge tables, and claims the same amount as input tax credit since freight is a business expense. Confirm from the transporter's invoice or declaration whether it has opted for forward charge, because paying RCM on an FCM invoice creates double taxation. Call +91 - 9600 606 444 if your freight entries need a review.

Question 9

I received an intimation in DRC-01C about ITC mismatch. How do I respond?

Accepted Answer

DRC-01C is issued under Rule 88D when the ITC claimed in your GSTR-3B exceeds the ITC available in GSTR-2B beyond the permitted limits. You must respond within seven days, either by paying the excess with interest through DRC-03 or by explaining the difference in Part B of DRC-01C, citing valid reasons such as credits of earlier periods claimed within time, reclaims after Rule 37 payment, or import ITC not flowing through 2B. Until you respond, the portal can block filing of your next GSTR-1. Do not ignore the seven-day window; call +91 - 9600 606 444 the day it arrives.

Question 10

Why is my nil return SMS to 14409 not working?

Accepted Answer

SMS filing fails for a few common reasons. The message must come from the exact mobile number registered against an authorised signatory on the GST portal, the format must match precisely with single spaces, and all returns for earlier periods must already be filed since GST returns are sequential. It also fails if the return is not truly nil, for instance if an amendment or credit note is pending to be reported. If one number is registered for multiple GSTINs, each needs its own SMS. We can diagnose the exact reason and file it online instead.

Question 11

What is the last date to file GSTR-9 for a financial year?

Accepted Answer

GSTR-9 for a financial year is due by 31 December of the following financial year. For example, the annual return for FY 2024-25 is due by 31 December 2025, unless the government extends the date by notification. The reconciliation statement GSTR-9C, where applicable, has the same due date and is filed after GSTR-9. Since annual return preparation involves reconciling twelve months of returns with books, we recommend starting by October rather than December. Businesses in Adyar can call +91 - 9600 606 444 to book an early slot with our annual returns team.

Question 12

I returned an advance because the deal was cancelled. What document do I issue?

Accepted Answer

It depends on how far the paperwork went. If you had issued only a receipt voucher and no tax invoice, you issue a refund voucher under Rule 51 when returning the advance, and the tax paid on that advance can be adjusted. If a tax invoice had already been issued, the cancellation is handled through a credit note under Section 34 instead. The refund voucher records the original receipt voucher reference, the amount refunded and the tax involved. Event managers and contractors see cancellations regularly, and using the wrong document between these two is a common reconciliation error.

Question 13

How is the place of supply decided when I sell goods?

Accepted Answer

Section 10 of the IGST Act gives the tests. Where the sale involves movement of goods, the place of supply is the location where the movement terminates for delivery to the recipient, whoever arranges the transport. Where there is no movement, it is the location of the goods at the time of delivery, which covers over-the-counter sales and sales of installed machinery in place. Where goods are assembled or installed at site, the place of supply is the site of installation. Getting this right decides whether you charge CGST plus SGST or IGST, and a Adyar seller delivering to a Bengaluru buyer charges IGST because delivery terminates in Karnataka.

Question 14

Does buying from unregistered dealers attract reverse charge for everyone?

Accepted Answer

No. The general reverse charge on all unregistered purchases under Section 9(4) was never fully implemented and now applies only to notified classes, principally real estate. A promoter must procure at least eighty percent of inputs and input services from registered suppliers for a project; on any shortfall, the promoter pays 18 percent under RCM, and cement purchased from an unregistered dealer attracts RCM at the rate applicable to cement, 18 percent since the September 2025 rate rationalisation reduced it from 28 percent, irrespective of the eighty percent test. Transfer of development rights and long-term leases to promoters are also covered. An ordinary trader or service provider in Adyar buying stationery from an unregistered shop has no Section 9(4) liability at all.

Question 15

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 16

Why are so many businesses suddenly receiving GST notices these days?

Accepted Answer

Enforcement has shifted from manual selection to data analytics. The portal now automatically compares GSTR-1 with GSTR-3B and flags tax shortfalls through DRC-01B intimations under Rule 88C, and compares GSTR-2B with GSTR-3B to flag excess ITC through DRC-01C under Rule 88D. E-way bill, e-invoice, TDS and income tax data are also cross-matched, and limitation deadlines for older financial years have pushed departments to clear pending demands in batches. The practical lesson for Adyar businesses is that mismatches no longer go unnoticed, so month-wise reconciliation before filing is now essential hygiene rather than a year-end exercise.

Question 17

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 18

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 19

Do you provide gst return filing for small businesses and proprietorships in Adyar?

Accepted Answer

Yes. A large share of our clients in Adyar are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.749/month 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 20

What documents are required for GSTR-1 & GSTR-3B monthly filing in Adyar?

Accepted Answer

For GSTR-1 & GSTR-3B monthly filing you will generally need: Sales invoices or sales register for the month, Purchase invoices or purchase register, Credit notes and debit notes issued during the month, GST portal login credentials, Bank statement for the period, if reconciliation is needed. 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 21

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.

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
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.
