Why Voluntary GST Registration is Beneficial in Assam

Even if your revenue is below the ₹20L/₹40L threshold, voluntary GST registration offers immense advantages:

  • B2B Billing: Corporate clients in Guwahati and across India demand GST invoices to claim input tax credit.
  • Current Bank Account: Banks require a GST certificate as a primary statutory entity document.
  • Input Tax Credit (ITC): Recover 18% GST paid on computers, laptops, cloud hosting, equipment, and raw materials.
