Which Exam Do You Appear In?
✅ Who qualifies as a "New Candidate"?
  • Income Tax Inspectors who have passed the Departmental Exam for Inspectors
  • Office Superintendents who have passed the Inspector exam
  • Tax Assistants who have passed the Inspector exam
  • Steno Grade-I & II who have passed the Inspector exam
  • Anyone who has not yet attempted the ITO exam under old rules OR attempted but not qualified any paper
📋 Papers to Appear In
  • All 5 papers of the New Pattern (DE Rules 2026) are mandatory
  • Paper I — IT Law & Taxpayer Services (with books)
  • Paper II — Advance Accountancy (without books)
  • Paper III — Allied Laws & Office Administration (with books)
  • Paper IV — Computation & Drafting (subjective)
  • Paper V — IT Applications & Operations (without books)
  • No choice — old pattern is not available to new candidates from 2026
📌 Key Rules
  • Maximum 10 chances to qualify the examination
  • Chances counted from 2010 examination onwards
  • No age bar for appearing
  • Pass marks: 50% in each paper (45% for SC/ST/PwBD)
  • Once you pass a paper, exempt from re-appearing in that paper
  • Withdrawal not allowed once application is permitted
ℹ️ Simple rule for new candidates: You have no choice — the New Pattern (DE Rules 2026) with all 5 new papers is the only option. The old DE Rules 2009 pattern is discontinued from 2026 onwards.
⚠️ Who is a "Partially Qualified" Candidate?
  • Someone who attempted the exam under DE Rules 2009 (old pattern) and has already passed 1, 2, or 3 papers but not all 5
  • Specifically: 3 or fewer papers still unqualified under old pattern
  • You are NOT required to re-appear in already-qualified papers
  • Old DE Rules 1998 candidates who were mid-way through 2009 matching also fall here
📋 What Papers to Appear In?
  • Appear only in the unqualified papers — matched to new pattern equivalents (see table below)
  • You must also qualify Paper V (IT Applications & Operations) — compulsory for all regardless of old qualification status
  • If you have less than 3 chances left, a minimum 3 chances are guaranteed exclusively for Paper V
Unqualified Paper (Old Pattern 2009) Matching Paper to Appear In (New Pattern 2026) Type
Paper 1 — IT Law & Computation (Without Books) Paper I — IT Law & Taxpayer Services (With Books) Objective
Paper 2 — Advanced Accountancy (Without Books) Paper II — Advance Accountancy (Without Books) Objective
Paper 3 — Allied Laws (Without Books) Paper III — Allied Laws & Office Administration (With Books) Objective
Paper 4 — IT & Accountancy Combined Practical (With IT Act) Paper IV — Computation of Income & Drafting (With IT Act) Subjective
No equivalent in old pattern Paper V — IT Applications & Operations — compulsory for ALL partially qualified candidates Objective
⚠️ Important: Passing the matched papers does NOT complete your exam — you must also pass Paper V (new addition with no old equivalent). Note that matched papers in 2026 have broader syllabus — e.g. Paper III now includes Office Administration which was not in old Paper 3.
🔵 Who Can Avail Betterment Chance?
  • SC/ST/PwBD candidates who have already fully qualified the examination — but under relaxed standards (at 45% instead of 50%)
  • They can re-appear to improve their marks to general standard (50%+)
  • Candidates who have NOT fully qualified are NOT eligible for betterment — they must first complete all papers
📋 Papers for Betterment
  • If qualified under Old Pattern with relaxed standard: appear in the matching paper(s) as per the paper-matching table
  • If qualified under New Pattern with relaxed standard: appear in the specific paper(s) of the new pattern
  • Subject to overall ceiling of 10 total chances (inclusive of chances already used)
❌ What Betterment Candidates Cannot Do
  • Cannot appear in papers they have already qualified at general standard (50%+)
  • Cannot exceed the overall 10-chance limit
  • Betterment is only for SC/ST/PwBD — general candidates have no betterment provision
ℹ️ Purpose of betterment: SC/ST/PwBD candidates are allowed to pass at 45% (relaxed standard). Betterment gives them additional chances to reach the 50% general standard, which may help in merit/seniority considerations. This is optional, not mandatory.
