Fundamentals of Income Tax and Tax Administration

What this domain tests

This domain checks whether you know the legal framework behind the tax calculation: the charging provision, the annual rate-fixing mechanism, the five heads of income, and the administrative machinery. Questions often test definitions and the order in which income is aggregated.

Core rules and concepts

  • Income tax is charged under the Income Tax Act, 1961. The rates for a financial year are fixed by the annual Finance Act, so the Act creates the charge and the Finance Act supplies the rates.
  • The Central Board of Direct Taxes (CBDT) administers direct taxes. The Assessing Officer (AO) assesses income; returns and forms are filed electronically through the income-tax portal.
  • A “person” includes an individual, HUF, firm, company, association of persons, and local authority. “Assessee” means a person by whom tax or another sum is payable.
  • The previous year (PY) is the year in which income is earned; the assessment year (AY) is the next year, in which that income is assessed.
  • Income is classified under five heads: salaries; house property; business or profession; capital gains; and other sources. Gross total income is the aggregate after intra-head adjustments. Total income is gross total income minus eligible Chapter VI-A deductions.

Worked example

A salaried employee earns salary of ₹8,00,000 and bank interest of ₹20,000. She invests ₹1,00,000 in PPF and pays ₹25,000 for her own medical insurance. Gross total income = ₹8,20,000. Chapter VI-A deductions = ₹1,00,000 under section 80C plus ₹25,000 under section 80D = ₹1,25,000. Total income = ₹6,95,000. Tax is then computed on ₹6,95,000 under the regime she validly chooses. Reasoning: aggregate head-wise income first, deduct only eligible Chapter VI-A amounts, then apply rates, rebate, surcharge, and cess.

Traps that cost marks

Do not confuse PY with AY. Do not subtract personal expenses from salary without a specific provision. A receipt is not automatically income. Rebate and surcharge are not deductions from income; they operate on the tax.
