Deductions under Section 24 – Standard Deduction & Interest

From NAV to final income - Section 24 provides 2 crucial deductions! 30% flat (no proof) + home loan interest (unlimited for let-out!). Let's maximize your tax savings.


Section 24 - Two Key Deductions

From Net Annual Value (NAV), deduct:

Section 24(a)"30% Standard Deduction (flat, no proof)"
Section 24(b)"Interest on Home Loan (limits apply)"

Result: Income from House Property


Section 24(a) - Standard Deduction (30%)

Flat 30% of Net Annual Value

No proof required!

Covers: Repairs, maintenance, collection charges

Applicable to:

  • Let-out property: Yes
  • Self-occupied: Yes (but NAV is Nil, so 30% of Nil = Nil)
  • Deemed let-out: Yes

Calculation: 30% × NAV

Example:

NAV = ₹4,00,000

  • Standard deduction: ₹4,00,000 × 30% = ₹1,20,000

No ceiling! If NAV is ₹50 lakh, deduction is ₹15 lakh (30%)


Section 24(b) - Interest on Home Loan

Interest paid on loan taken for:

  1. Purchase of house property
  2. Construction of house property
  3. Repair/Renovation/Reconstruction

Conditions:

  • Loan from bank/housing finance company (or any source)
  • Interest actually paid (not accrued)

Limits:

Self-Occupied Property

  • Maximum: ₹2,00,000 per year
  • For purchase/construction
  • Pre-construction interest allowed (5 years)
  • Creates loss (NAV is Nil)
VS

Let-Out Property

  • For purchase/construction/repair
  • Pre-construction interest allowed (5 years)

Self-Occupied: ₹2 Lakh Limit

Maximum deduction: ₹2,00,000 per year

Even if actual interest paid is ₹5 lakh → Deduct only ₹2L

Exception - ₹30,000 limit:

If loan taken for repair/renovation (not purchase/construction):

  • Limit: ₹30,000 only

Example 1 (Purchase loan):

  • Home loan interest: ₹2,80,000

  • Balance ₹80,000: Not deductible

Example 2 (Renovation loan):
