India’s taxation system is built on laws that evolve with economic needs, digital advancements, and taxpayer convenience. The Income-tax Act, 1961, which governs direct taxation, continues to undergo amendments—most recently reflected in the Income-tax Act, 2025 (India) framework. Whether you are a salaried professional, business owner, or investor, understanding the latest updates, compliance procedures, and key sections is crucial for accurate tax filing and financial planning.
In this comprehensive guide, we break down important provisions of the Act, explain essential terms like income tax, e-filing, ITR notices, tax exemptions, deductions, and more.
What is Income Tax?
Income tax is a direct tax imposed by the Government of India on the income earned by individuals, Hindu Undivided Families (HUFs), firms, LLPs, and companies. It is managed by the Income Tax Department, operating under the Central Board of Direct Taxes (CBDT).
Every year, taxpayers must calculate their total taxable income, claim exemptions and deductions, pay the applicable tax, and file an Income Tax Return (ITR).
The Income-tax Act, 1961: The Parent Law
Although we refer to the Income-tax Act, 2025, it is not a separate act. Instead, it represents the latest version of the Income-tax Act, 1961 after the government introduces annual Finance Act amendments.
The Act defines:
-
What constitutes taxable income
-
How tax rates are determined
-
Powers of income tax authorities
-
Penalties for non-compliance
-
Exemptions, deductions, and reliefs
-
Rules for assessments and appeals
Recent Income-tax Act 1961 news updates focus heavily on digital tax administration, faster processing of returns, and strict monitoring of unreported income using data analytics.

Timely filing also helps establish financial credibility for:
