<h1>Income Tax Department Unveils Tool for Transition to Simplified 2025 Bill; Streamlines Sections and Chapters</h1> The Income Tax department has launched a section-wise mapping tool on its portal to align the Income Tax Act, 1961, with the new simplified Income Tax Bill, 2025. This Bill, introduced in the Lok Sabha, aims to replace the outdated 1961 Act with a more concise and user-friendly version. The new Bill reduces sections from 819 to 536 and chapters from 47 to 23, while adding more tables and formulae for easier tax calculation. It introduces the 'tax year' concept and eliminates redundant sections and complex language. The Bill is expected to be effective from April 1, 2026, pending parliamentary approval.
