GST Registration & Returns — set up right, then filed on time, every month

Most GST trouble is not the tax, it is a missed return, a wrong registration category, or input credit lost because the supplier’s data didn’t match. We set the registration up correctly and run the monthly cycle so notices never start.

Quick summary. GST registration is compulsory once your aggregate turnover crosses ₹40 lakh (goods) or ₹20 lakh (services), and from day one, regardless of turnover, if you sell inter-state, supply through an e-commerce operator, or fall under reverse charge. After registration, the recurring work is GSTR-1, GSTR-3B and annual returns, with input-tax-credit matched against GSTR-2B. We handle registration end-to-end and run the monthly filing so deadlines and credit are never missed.

Frequently asked questions

When is GST registration compulsory?

Once your aggregate turnover (all-India, on one PAN) crosses ₹40 lakh for goods or ₹20 lakh for services, ₹20 lakh and ₹10 lakh respectively in special-category states. It is also compulsory from the first rupee, regardless of turnover, if you make inter-state supplies, supply through an e-commerce operator, are a casual or non-resident taxable person, or are liable under reverse charge.

Should I choose the regular scheme or the composition scheme?

The composition scheme (turnover up to ₹1.5 crore for goods, ₹75 lakh in special-category states; a separate ₹50 lakh route for service providers) means a low flat tax and a simple quarterly statement, but you cannot collect GST from customers or claim input tax credit, and you cannot make inter-state sales. Regular registration is the right choice if you sell inter-state, supply to businesses that want credit, or have significant input tax to recover. We assess which actually costs you less.

How long does registration take?

Usually 3 to 7 working days from a complete application, assuming the department raises no query. If a clarification (Form REG-03) is raised, we respond and the timeline extends by a few days.

Which returns will I have to file, and how often?

A regular taxpayer files GSTR-1 (sales) and GSTR-3B (summary and payment) either monthly, or quarterly under the QRMP scheme if turnover is up to ₹5 crore, plus an annual GSTR-9. GSTR-9C reconciliation applies above ₹5 crore. Composition dealers file a quarterly CMP-08 and an annual return instead.

What happens if I file late or miss a return?

A late fee of ₹50 per day (₹20 per day for nil returns) applies, along with interest at 18% per annum on any unpaid tax. Persistent non-filing can lead to your input credit being blocked, your e-way bills being stopped, and eventually a notice. Running the calendar on time is what avoids all of this.

Can I claim input tax credit on my purchases?

Yes, on goods and services used for business, provided the supplier has reported the invoice so it appears in your GSTR-2B, you hold a valid tax invoice, and you have paid the supplier within 180 days. We reconcile GSTR-2B every month so you claim exactly what is available and don’t carry mismatches.

Do I need a separate registration for each state?

Yes. GST is state-wise, you need a registration for every state from which you make taxable supplies, each with its own GSTIN under the same PAN. We handle multi-state registrations and keep the filing aligned across them.

Is e-invoicing applicable to me?

E-invoicing is mandatory once your aggregate turnover crosses ₹5 crore in any financial year. We set up the e-invoicing process and integrate it with your invoice format so it runs without disrupting billing.
