Section 21 · was Section 23 in the 1961 Act
The annual value is the amount the property can reasonably be expected to fetch as annual rent. For a self-occupied property (up to 2), the annual value is nil. For let-out property, it is the higher of actual rent or expected market rent.
Who it applies to: All property owners — relevant for computing taxable income from house property.
Suresh rents his flat to his brother at ₹8,000/month. The market rent for similar flats in the area is ₹20,000/month.
Actual rent received: ₹8,000 × 12 = ₹96,000
Fair market rent: ₹20,000 × 12 = ₹2,40,000
Annual value = Higher of (actual rent, market rent)
= ₹2,40,000
Net annual value after municipal taxes (say ₹12,000):
= ₹2,40,000 – ₹12,000 = ₹2,28,000Result: Suresh is taxed on ₹2,28,000 (market rent basis), not on ₹96,000 (actual rent). The below-market rental to a family member does not reduce his tax.
