GST Registration – Frequently Asked Questions

Explore commonly asked questions about GST Registration in India. Learn about the costs involved, legal formalities, and key advantages to help you make confident and informed choices.

GST return filing is the submission of a business’s sales, purchases, taxes paid, and input tax credits (ITC) in prescribed formats to tax authorities. It ensures proper ITC claims and compliance with GST laws.

Note: It’s not legally distinct from the owner, meaning the business and the individual are treated as one for taxation and liability.

A GST return is a document that details all sales, purchases, tax collected on sales, and tax paid on purchases. Every GST-registered taxpayer (identified by a GSTIN) is required to file these returns with the tax authorities. The tax department determines the taxpayer’s net tax liability with these returns.

Note: Registration helps in opening a current bank account, getting GST, and accessing business loans or government schemes.

The composition scheme allows small businesses with turnover up to ₹1.5 crores (₹75 lakhs for specific states) to pay a fixed percentage of turnover as tax instead of regular GST rates.

Note: Document requirements may vary depending on state rules and the type of business.

There are 22 types of GST returns, but only a few apply to most taxpayers, such as GSTR-1, GSTR-3B, GSTR-9, and GSTR-4 (for composition taxpayers).

Note: Timelines can vary based on your location and the responsiveness of government portals.

Late filing attracts a penalty of ₹50 per day (₹20 for NIL returns) and 18% annual interest on unpaid tax. Continuous non-filing may lead to GST registration cancellation.

Note: However, all employment-related compliance like TDS and labour law registration must be handled by the owner.

  • Costs vary based on the filing method:
  • Self-filing: ₹0 (only time cost)
  • Online platforms: ₹250 – ₹2,000 per month
  • Professional online CA consultation: ₹500 – ₹5,000 per return

Note: You can operate under your own name or a chosen business name, but make sure it’s not already in use.

Follow these steps to file GST returns on the GST portal:

  • Log in to www.gst.gov.in
  • Select the return type (e.g., GSTR-1, GSTR-3B)
  • Upload invoices and tax details
  • Preview, validate, and submit the return
  • Pay the required GST, if applicable.

No, GST returns cannot be revised. Corrections must be made in the next filing by adjusting errors in subsequent returns.

Note: Voluntary GST registration can also help you build business credibility and claim input tax credit.

The Quarterly Return Monthly Payment (QRMP) scheme allows taxpayers with turnover up to ₹5 crores to file GSTR-1 and GSTR-3B quarterly while making monthly tax payments, reducing compliance burden.

Note: This involves transferring assets, reapplying for registrations, and following MCA procedures.

Businesses with an annual turnover of up to ₹5 crores can opt for QRMP to file returns quarterly instead of monthly while paying tax monthly.

Note: It’s best suited for freelancers, small traders, local services, and early-stage entrepreneurs.
