GST Registration and Return Filing

From first-time GST registration to ongoing GSTR-1 and GSTR-3B filing, we keep your business compliant and help you avoid interest and late fees. We also handle input tax credit reconciliation, annual returns, refund claims and replies to GST department queries.

Who this is for

  • Traders, shops and distributors in Koderma and nearby districts
  • Manufacturers and contractors
  • Online sellers on marketplaces
  • Service providers crossing the registration threshold

What's included

  • New GST registration, amendments and cancellation
  • GSTR-1, GSTR-3B and QRMP scheme filing
  • Input tax credit reconciliation with GSTR-2B
  • Annual return (GSTR-9) and reconciliation statement (GSTR-9C) where applicable
  • GST refund claims and replies to notices and ASMT queries

Documents you will need

  • PAN and Aadhaar of the proprietor, partners or directors
  • Business address proof (electricity bill, rent agreement or NOC)
  • Bank account details (cancelled cheque or statement)
  • Photographs of the proprietor or partners
  • Sales and purchase invoices for ongoing return filing

Key deadlines

  • 111th of the following month: GSTR-1 (monthly filers)
  • 220th of the following month: GSTR-3B (monthly filers)
  • 313th and 22nd/24th of the month after the quarter: GSTR-1 and GSTR-3B under the QRMP scheme

Common mistakes we help you avoid

  • 1Claiming input tax credit that does not appear in GSTR-2B
  • 2Missing a nil return when there were no sales in a month
  • 3Assuming every online seller must register: small intra-state sellers of goods have conditional relief
  • 4Not amending the registration after a change of address or partners

Deadlines and procedures above reflect the law as we understand it on 9 November 2026. They change, and exceptions apply. Confirm the dates for your case with us before relying on them.

Do you need to register?

GST registration depends mainly on your aggregate turnover, and the limit is different for goods and for services. Some businesses must register regardless of turnover, for example those making certain inter-state supplies or selling through e-commerce platforms, subject to specific exceptions. We check which rule applies to your business before you apply, because registering unnecessarily brings monthly compliance, and not registering when required brings tax, interest and penalties.

Regular scheme or composition scheme

Small businesses can choose the composition scheme, which means paying tax at a fixed rate on turnover with simpler, less frequent returns. The trade-off is that a composition dealer cannot charge GST on invoices or claim input tax credit, and some kinds of business are not eligible. For a business that buys from GST-registered suppliers and sells to registered customers, the regular scheme is often better. We compare both with you.

The return cycle

  • GSTR-1 reports your sales invoice by invoice. Your customers’ input tax credit depends on it, so late or wrong GSTR-1 filing affects them too.
  • GSTR-3B is the summary return through which tax is actually paid.
  • QRMP scheme: smaller taxpayers can file returns quarterly while paying tax monthly.
  • Annual return (GSTR-9) and, where applicable, the reconciliation statement (GSTR-9C) close the year.

Exact due dates are in the Key deadlines list on this page and change from time to time.

Getting input tax credit right

Input tax credit is where most GST problems start. Credit can generally be claimed only when the supplier has reported the invoice so that it appears in your GSTR-2B, you have received the goods or services, you hold the invoice, and the supplier has paid the tax. We reconcile your purchase register with GSTR-2B every period, follow up on missing invoices and keep credits that are not yet eligible separate, so the books and returns agree.

E-invoices, e-way bills and records

Depending on turnover and the kind of goods, you may need to generate e-invoices or e-way bills. GST law also requires accounts and records to be kept for several years. Keeping invoices, credit notes and e-way bills organised month by month makes annual returns and any later enquiry much easier.

Notices and enquiries

GST notices usually arise from differences between returns: GSTR-1 against GSTR-3B, or credit claimed against GSTR-2B. Others relate to registration, refunds or assessments. Each notice has a reply deadline on the portal. We review the notice, reconcile the figures behind it and draft the reply with supporting statements.
