In India, one can obtain a free Employer Identification Number (EIN), also known as a Taxpayer Identification Number (TIN), by applying through the website of the Income Tax Department of India or a designated portal, where you'll find the application form for TIN registration. Fill out the required details accurately, including your business information and financial data. Attach any necessary documents, such as PAN cards or proof of address. After submission, the tax authorities will process your application, and upon approval, they will issue your TIN, allowing you to conduct business legally and in fulfilling your tax obligations.
