Important Note

With effect from 1 April 2026, the provisions of the Income Tax Act, 2025 have come into force.

  For all transactions from April 2026 onwards, earlier section references such as 194C, 194J, 194H, etc. should no longer be used. These have now been consolidated under Sections 392, 393, and 394 of the new Act.

  Additionally, note that Form 16 has been renamed as Form 130 for Tax Year 2026–27 onwards—ensure systems and documentation are updated accordingly.

Stay on top of these deadlines to avoid costly penalties and late fees. Mark your calendars and plan ahead to ensure a smooth compliance process.
