Income tax serves as a key revenue source for the government, levied on individuals' and businesses' earnings. In India, it follows the Income Tax Act, 1961, with updates for FY 2025-26. Taxpayers must file returns annually to report income and claim refunds.
What is Income Tax?
Income tax is a direct tax on annual earnings from salary, business, property, or capital gains during a financial year. Governed by the Income Tax Act, 1961, it mandates filing Income Tax Returns (ITR) by due dates, either online or offline via the official portal. Failure to file incurs penalties under Section 234F.

India offers old and new tax regimes; the new one is default for FY 2025-26 with higher exemption limits. Under the new regime, income up to Rs. 12.75 lakhs is tax-free for salaried individuals, with slabs at 5%, 10%, 15%, 20%, and 30% for higher brackets. Choose based on deductions available in the old regime.
