📄 Understanding Section 143(3) & 144B of the Income Tax Act – Scrutiny Assessment in India
🔍 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.
💻 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)
- Communication only through electronic mode via the Income Tax portal
⏱️ Time Limits under Section 143(3) and 144B
1. 📬 Time Limit for Issuance of Notice (Section 143(2)):
- Notice under Section 143(2) must be issued within 3 months from the end of the financial year in which the return was filed.
Example:
If you filed your return for AY 2024-25 on 31 July 2024, then the last date to issue notice under Section 143(2) is 30 June 2025.
