Important Information

Why is it important to verify GSTIN?

Verifying a GST Number (GSTIN) is crucial. It prevents fraud from manipulated GSTINs, ensures transparency in business transactions, and helps in filing correct GST returns. Most importantly, proper verification allows you to claim Input Tax Credit (ITC) which you might otherwise lose due to fake GSTINs.

By verifying GSTINs, you ensure that your tax payments reach the government correctly and contribute to nation-building.
