Quick revision

  • Faceless assessment under section 273 applies to areas, persons, incomes or cases specified by the Board.
  • The National Faceless Assessment Centre assigns the case to an assessment unit, intimates the assessee and serves notices.
  • The assessment unit analyses material, identifies issues, seeks clarification and determines any variation prejudicial to the assessee.
  • The verification unit does enquiry, cross verification, examination of books and witnesses, and recording of statements.
  • The technical unit gives legal, accounting, forensic, IT, valuation, transfer pricing and data analytics advice.
  • The review unit reviews proposed variations where the Centre considers it necessary.
  • Communication among units, and with the assessee, goes through the Centre; with the assessee it is exclusively electronic.
  • The assessment unit makes the assessment by a written order after hearing the assessee, and may initiate penalty proceedings.
  • The Centre's head may transfer a case to the jurisdictional Assessing Officer at any stage with the Board's prior approval.
  • Faceless assessment means e-Proceeding through the assessee's registered account on the designated portal.
  • Section 279(3): Assessing Officer for sections 280 and 281 excludes the Centre and assessment units.
  • Under section 359, the appellate order must be in writing, with points for determination, decision and reasons.

Common mistakes

  • Treating self-assessment as an assessment order made by the officer. Fix: Self-assessment is the tax you pay yourself before filing. It appears as a credit under section 270(1)(c)(v). The orders are the intimation and the regular assessment order.
  • Counting the nine-month and three-month limits from the date of filing the return. Fix: Both run from the end of the financial year in which the return is made or furnished. Mark 31 March first, then add the months.
  • Saying every assessment is faceless. Fix: State that it applies only to the areas, persons, incomes or cases specified by the Board.
  • Writing about regional faceless assessment centres as part of section 273. Fix: Section 273(3) names the National Faceless Assessment Centre and the four types of units. Stick to that text.
  • Saying the assessment unit directly writes to the assessee. Fix: Under section 273(7), communication goes through NaFAC, which forwards your response to the assessment unit.
  • Treating all assessments as faceless. Fix: Section 273(2) limits it to what the Board specifies. State this condition.
  • Saying every faceless assessment order goes to the Commissioner (Appeals) only. Fix: Mention both. Section 356 applies to orders of an officer below Joint Commissioner rank, subject to the section 356(2) bar.
  • Ignoring the section 356(2) bar. Fix: Always check who passed the order or approved it. Above Deputy Commissioner rank means no appeal to the Joint Commissioner (Appeals).

Exam tips

  • Quote section 270 sub-section numbers in your answer. Examiners reward the provision first, then the facts.
  • Memorise the six adjustment heads and the three limbs of incorrect claim. These are the commonest short-answer asks.
  • Always compute time limits from the end of the financial year, and show the date you reach.
  • In numerical questions, list credits one by one from section 270(1)(c). It earns method marks even if the final figure slips.
  • Define self-assessment, processing and regular assessment in one line each, then distinguish them by hearing, evidence and nature of order.
  • Write answers in the order provision, analysis, conclusion, and quote sub-section numbers such as 273(3), 273(7) and 273(12).
  • Use a short list for the four units and give one function for each. Examiners look for all four.
  • Always state that scope is fixed by the Board under sub-section (2). It is an easy mark.
