GST Services, Registration & Filing in Mysore

GST registration is the process of enrolling your business with the Goods and Services Tax Network (GSTN) to obtain a unique 15-digit GSTIN. Once registered, you are authorised to collect GST from customers, claim Input Tax Credit on your purchases, and file periodic returns. In Karnataka, GST registration is mandatory if your aggregate annual turnover exceeds ₹40 lakhs for goods or ₹20 lakhs for services. Registration is also mandatory regardless of turnover if you make inter-state supplies, sell through e-commerce platforms, or are liable to pay tax under the Reverse Charge Mechanism. Businesses below the threshold can register voluntarily — which is often commercially advantageous.

The standard documents required for GST registration for a business in Mysore are:

• PAN card of the business / proprietor / partners / directors
• Aadhaar card of the authorised signatory
• Proof of business address — electricity bill, municipal tax receipt, or rent/lease agreement
• Bank account details — cancelled cheque or bank statement
• Photographs of proprietor / partners / directors
• Business constitution documents — partnership deed, LLP agreement, MOA & AOA for companies, or Certificate of Incorporation
• Digital Signature Certificate (DSC) for companies and LLPs

Our team collects and reviews all documents before filing to avoid rejections or officer queries.

Late filing of GST returns has a direct financial cost. For GSTR-3B, the late fee is ₹50 per day for returns with a tax liability (₹20 per day for nil returns), subject to a maximum of ₹10,000 per return. Additionally, any unpaid GST liability attracts interest at 18% per annum from the due date. Beyond fees and interest, repeated non-filing can lead to cancellation of your GST registration, blocking of your GSTIN on the e-way bill portal (preventing you from moving goods), and initiation of best judgement assessment by the GST officer. It also makes you ineligible for GST refunds until all pending returns are filed.

Yes, in most practical cases. If your startup's projected revenue will cross the threshold (₹20 lakhs for services, ₹40 lakhs for goods) within the year, early registration is advisable — you cannot retroactively claim ITC on purchases made before registration. More importantly, if your startup sells to GST-registered businesses (B2B), your customers will expect a GST invoice so they can claim ITC. An unregistered vendor creates a tax credit gap for the buyer — making you commercially less attractive than a GST-registered competitor. For startups in IT, SaaS, consulting, or manufacturing, GST registration is practically essential from day one. Startups may also benefit from the Composition Scheme if eligible, which simplifies compliance to a quarterly return and a fixed tax rate on turnover.

Under the regular GST scheme, your GST liability = Output GST (GST collected on sales) minus Input Tax Credit (GST paid on purchases and eligible expenses). You pay only the net amount to the government. For example: If you sell goods worth ₹10 lakhs attracting 18% GST, your output tax is ₹1,80,000. If you purchased inputs worth ₹6 lakhs with ₹1,08,000 of GST paid, your net GST payable is ₹72,000. Small businesses with turnover up to ₹1.5 crores (goods) may opt for the Composition Scheme, under which they pay a fixed percentage of their turnover as tax (1% for manufacturers and traders, 5% for restaurants, 6% for service providers) and file only a quarterly return. The trade-off is that Composition dealers cannot collect GST from customers or pass ITC to them — making it suitable mainly for B2C businesses. Our GST consultant team helps you evaluate which scheme best fits your business model before registration.
