Additionally, using a digital signature for income tax from the filing portal is crucial to reporting their earnings accurately and claiming deductions on business expenses.

Business Owners

Individuals running a business, a small enterprise, or a large corporation need to register DSC on the Income Tax portal to file returns. This is to report profits, losses, and other financial activities. In addition, different types of businesses have different tax obligations, such as sole proprietorships, partnerships, or corporations.


Individuals earning income from investments must report it on their tax returns. These include stocks, bonds, mutual funds, dividends, interest, real estate, and much more. Furthermore, tax rates for investment income can vary depending on factors like the duration of investment and the type of asset. Individuals may utilize a digital signature for income tax submissions to comply with tax regulations.

Who is Not Eligible for Income Tax in India?

Non-resident Indians (NRIs) follow special tax rules. They pay tax only on income earned in India as the revenue from abroad is not taxable in India.

NRIs might be eligible for certain exemptions and deductions similar to resident Indians based on the nature of income and investments.
