When you actually have to register

GST registration becomes mandatory once aggregate turnover crosses ₹40 lakh for a supplier of goods or ₹20 lakh for a supplier of services. In the special category states those thresholds halve, to ₹20 lakh and ₹10 lakh. Turnover is not the only trigger. Registration is compulsory regardless of turnover if you make inter-state supplies of goods, operate an e-commerce platform or sell through one, are a casual taxable person, or are liable to pay tax under reverse charge. Plenty of startups also register voluntarily well below the threshold, because their customers want an invoice they can claim credit against.

Which returns you file, and when

A monthly filer files GSTR-1 by the 11th of the following month and GSTR-3B by the 20th. Businesses with turnover up to ₹5 crore can opt into QRMP, which makes GSTR-1 quarterly with an optional Invoice Furnishing Facility for the first two months of the quarter, and GSTR-3B quarterly on the 22nd or 24th depending on the state. The annual return, GSTR-9, is due by 31 December following the financial year, with the GSTR-9C reconciliation statement on top of it above ₹5 crore. Composition dealers file CMP-08 each quarter and GSTR-4 annually.

What late filing costs

The late fee is ₹50 a day for a normal return — ₹25 under CGST and ₹25 under SGST — and ₹20 a day for a nil return. It is capped by turnover: ₹2,000 up to ₹1.5 crore, ₹5,000 between ₹1.5 crore and ₹5 crore, and ₹10,000 above that. Tax paid late carries interest at 18% a year; input tax credit wrongly claimed and utilised carries 24%. The cash cost is rarely the real cost. GSTR-3B for a period cannot be filed until GSTR-1 for that period is filed, so one skipped return blocks the next one. And your customer cannot claim credit on an invoice you have not reported — which is how a missed filing turns into a collections conversation.

Input tax credit, reconciled every month

Most GST notices start life as a mismatch between what a business claimed in GSTR-3B and what its GSTR-2B actually shows. We reconcile the two every month, flag the suppliers who have not filed, and tell you which credits to hold back rather than claim now and reverse later with interest attached.

How Bentham runs it

Registration, monthly or quarterly filing, GSTR-2B reconciliation, the annual return, and e-way bills where you need them. A dedicated CA reviews each return before submission, and you get a reminder ahead of every due date. If a notice does arrive, the same person who filed the return drafts the reply.
When is GST registration mandatory?+

GST registration is mandatory when your aggregate turnover exceeds ₹20 lakhs (₹10 lakhs for special category states) in a financial year. It is also mandatory for inter-state suppliers, e-commerce sellers, and businesses required to deduct TDS regardless of turnover.

What is the penalty for late GST filing?+

Late filing of GSTR-3B attracts a late fee of ₹50/day (₹20/day for nil returns) capped at ₹5,000 per return, plus interest at 18% per annum on the tax liability. Consistent late filing can also lead to GST registration cancellation.

What is Input Tax Credit (ITC) and how does it work?+

ITC allows you to reduce your GST liability by claiming credit for GST already paid on business purchases. For example, if you collect ₹18,000 GST on sales and paid ₹10,000 GST on purchases, you only remit ₹8,000 to the government. Bentham auto-reconciles your ITC with GSTR-2B data.

Which GST returns do I need to file and when?+

Regular taxpayers file: GSTR-1 (outward supplies) by 11th of next month, GSTR-3B (summary return with tax payment) by 20th of next month, and GSTR-9 (annual return) by 31 December. Composition scheme taxpayers file CMP-08 quarterly instead.

How long does GST registration take?+

Once all documents are in order, the GSTIN is usually issued within about 7 working days, assuming no clarification (Form GST REG-03) is raised by the department. If the officer asks for a clarification, it can take an additional 4 working days.

Is GST registration mandatory for my business?+

Not always. It becomes mandatory once you cross the turnover threshold (₹40 lakh for goods, ₹20 lakh for services, lower in special-category states), or immediately — regardless of turnover — if you make inter-state supplies, sell through e-commerce platforms, or fall under a few other specified categories. If you're unsure, a quick call will tell you exactly where you stand.

Can I register voluntarily even if I'm below the threshold?+

Yes, and it's sometimes worth it. Voluntary registration lets you claim input tax credit and can make you more credible to larger clients who prefer GST-registered vendors. We can walk you through whether it makes sense for your business.

Can you help me claim input tax credit correctly?+

Yes. Claiming ITC accurately is where most businesses lose money or invite notices. We reconcile your purchase data against GSTR-2B before filing so you claim everything you're entitled to and nothing you're not.

I've received a GST notice. Can you help?+

Yes. Schedule a call with our team — we'll review the notice, explain what it means, and handle the response and any follow-up filings. https://cal.id/bentham/intro-call

Do you handle GST registration too, or only filing?+

Both. We get you registered and then manage your ongoing returns, so it's one continuous service.

What documents are required for GST registration?+

For a private limited company, you'll typically need: the company PAN, Certificate of Incorporation, MOA and AOA, the PAN, Aadhaar and a photograph of the authorized signatory and each director, a board resolution or authorization letter for the signatory, proof of the principal place of business (electricity bill, rent agreement, and a No Objection Certificate if the premises are rented), and bank account proof.
