Before computing Income from House Property, it is essential to clearly understand the concepts of Gross Annual Value (GAV) and Net Annual Value (NAV). These two terms form the foundation of house property taxation, and most numerical problems begin with their correct determination.
If you read this blog carefully, you will be able to understand:
- what Gross Annual Value actually represents,
- how Net Annual Value is derived from GAV, and
- why correct computation of GAV and NAV is crucial for calculating taxable income or loss from house property.
To make clear the concepts of Gross Annual Value (GAV) and Net Annual Value (NAV), let us take some numerical examples
GAV represents the maximum reasonable rent a property can earn.
Assume:
- Municipal Value = Rs. 3,20,000
- Fair Rent =Rs. 3,40,000
- Standard Rent (Rent Control Act) = Rs.3,30,000
- Actual Rent Received = Rs.3,50,000
Rule:
GAV = Higher of Municipal Value or Fair Rent,
but restricted to Standard Rent
Higher of MV & FR = RS.3,40,000
Standard Rent = Rs.3,30,000
Gross Annual Value = Rs.3,30,000
Net Annual Value (NAV)
Gross Annual Value xxxx
Less: Municipal Taxes (paid by owner)
- Municipal Taxes paid = Rs.30,000
NAV = GAV – Municipal Taxes
Rs.3,30,000 – Rs30,000 = Rs.3,00,000
Deductions under Section 24 – Reliefs allowed by law
Two deductions are allowed only after NAV is determined:
(a) Standard Deduction – 30% of NAV
30% of Rs.3,00,000 = Rs.90,000
(Allowed irrespective of actual expenses)

(b) Interest on Housing Loan
- Interest paid on loan = Rs.1,80,000 (assumed)
Computation of Income from House Property
Computation
| Particulars | Amount (Rs) |
| Net Annual Value | 3,00,000 |
| Less: Standard Deduction (30%) | (90,000) |
| Less: Interest on Loan | (1,80,000) |
| Income from House Property | 30,000 |
Result: Income from House Property = Rs. 30,000
Remember:
Key Takeaways for Beginners
- GAV = capacity of the house to earn rent
- NAV = real taxable value after municipal taxes
- Standard Deduction (30%) is automatic
- Interest on loan can convert income into loss
- Loss from house property reduces tax burden
Income from Self-Occupied House Property
Gross Annual Value (GAV) – Special rule for SOP
When a house is used for own residence, its Gross Annual Value is taken as NIL.
Even if:
- Municipal Value exists
- Fair Rent exists
- Market rent is high
All ignored and GAV = NIL
Net Annual Value (NAV)
Since:
- GAV = NIL
- Municipal taxes are irrelevant and
NAV = NIL
Deductions under Section 24 – Only Interest Matters
(a) Standard Deduction (30%)
Allowed only if NAV exists
NAV = NIL and therefore no standard deduction.
Interest on Housing Loan (Section 24(b))

This is the most important deduction for SOP.
Assume:
- Interest on housing loan during the year = Rs.2,50,000 (assumed)
- Loan taken for purchase of house
- Construction completed within 5 years
Maximum deduction allowed = Rs.2,00,000
Allowable interest = Rs.2,00,000
Excess Rs.50,000 is ignored
Income / Loss from Self-Occupied House Property
Computation of Income from
| Particulars | Amount (₹) |
| Net Annual Value | NIL |
| Less: Interest on Loan (allowed) | (2,00,000) |
| Income from House Property | (2,00,000) Loss |
Loss from SOP = Rs.2,00,000
Comparison Snapshot: Let-Out vs Self-Occupied
| Particulars | Let-Out Property | Self-Occupied Property |
| GAV | Based on rent rules | NIL |
| NAV | GAV – Municipal tax | NIL |
| Standard Deduction | 30% of NAV | Not allowed |
| Interest Deduction | Full amount | Max Rs.2,00,000 |
| Result | Income or Loss | Always loss or nil |
An individual / HUF can treat up to TWO house properties as self-occupied,
provided both are used for own residence or kept vacant for own use.
Mr. Sanjib Sen owns TWO residential houses:
| House | Usage |
| House A | Used for own residence |
| House B | Kept vacant for own use |
As per new rule
- Both House A and House B can be treated as Self-Occupied (SOP)
- No deemed let-out arises
Tax Treatment of Both SOPs
For each Self-Occupied Property:
- Gross Annual Value (GAV) = NIL
- Net Annual Value (NAV) = NIL
- Standard deduction = Not allowed
Interest on Housing Loan:
- Interest deduction allowed for each house
- Overall ceiling = Rs.2,00,000 (combined)
This is a very common exam trap:
Limit is NOT Rs. 2,00,000 per house,
It is Rs.2,00,000 in total for both SOPs.

Combined Computation (Illustration)
Assume:
- Interest on loan for House A = Rs.1,20,000
- Interest on loan for House B = Rs.1,10,000
- Total interest = Rs.2,30,000
- Allowable deduction = Rs.2,00,000 only
Income from House Property
| Particulars | Amount (Rs.) |
| GAV (Both SOPs) | NIL |
| Less: Interest (restricted) | (2,00,000) |
| Income from House Property | (2,00,000) Loss |
Revision Summary Chart
| Type | Meaning |
| Self-Occupied Property (SOP) | Used for own residence or kept vacant for own use |
| Let-Out Property (LOP) | Actually, given on rent |
| Deemed Let-Out (DLOP) | Vacant property (beyond 2 SOPs) treated as let-out |
| Maximum SOP allowed | TWO houses |
| 3rd house onwards | Deemed let-out |
