- Section 10(13A)
- The Income Tax Act provision that exempts a portion of House Rent Allowance from tax for salaried employees who actually pay rent. Read with Rule 2A of the Income Tax Rules, 1962, which specifies the rule of three for computing the exempt amount.
- Basic + DA
- The basic salary plus Dearness Allowance components of your CTC, used as the denominator in the HRA formula. DA forms part of basic only when it forms part of retirement benefits per the employment terms; otherwise basic alone is used.
- Metro (for HRA)
- Strictly Mumbai, Delhi, Kolkata and Chennai per §10(13A). Bangalore, Hyderabad, Pune, Ahmedabad and other cities are non-metros for HRA purposes regardless of population, cost of living or municipal classification.
- Form 12BB
- The standard form an employee submits to their employer at the start of each financial year (and revised in January) declaring rent paid, landlord's name and PAN (if applicable), §80C investments, home loan interest and other tax-saving claims so that TDS can be computed accurately.
- Rule 2A
- The Income Tax Rules provision that operationalises §10(13A). It explicitly defines the three amounts and states that the least is exempt. It also clarifies that 'salary' for HRA purposes excludes overtime, commission (except commission on turnover at a fixed percentage), bonus and any other allowance.
- Old vs New Tax Regime
- The old tax regime allows deductions and exemptions including HRA, §80C and §80D, but applies higher slab rates. The new regime under §115BAC applies lower slab rates but disallows HRA, §80C investments (except employer NPS contribution) and most other deductions. Choice is made annually in the ITR.
- Rent Receipt
- A signed acknowledgement from a landlord confirming receipt of rent for a specified period. Income Tax authorities accept rent receipts plus, where applicable, the landlord's PAN as primary evidence of rent paid. Receipts on rent above ₹3,000 a month should bear a revenue stamp.
