๐ Understanding Section 143(3) & 144B of the Income Tax Act โ Scrutiny Assessment in India
๐ What is Section 143(3)?
Section 143(3) provides for a detailed scrutiny assessment by the Income Tax Department. In this assessment, the Assessing Officer (AO) examines the return filed by the taxpayer in depth to ensure the correctness of:
- Total income reported
- Claims of deductions, exemptions, expenses
- Transactions reported in Form 26AS, AIS/TIS, etc.
The AO may ask for further information, documents, and explanations before finalizing the assessment.
๐ป What is Section 144B?
Section 144B lays down the faceless assessment procedure, under which assessment is conducted digitally without physical interaction. It ensures:
- Complete transparency and accountability
- Assessment by specialized units (Assessment Unit, Verification Unit, Technical Unit, Review Unit)
