Computation format and determination of Gross Annual Value (GAV) and Net Annual Value (NAV)

## Computation of Income from House Property

### The standard format

Gross Annual Value (GAV)XXXX
Less: Municipal Taxes paid(XXX)
Net Annual Value (NAV)XXX
Less: Deductions u/s 24
  (a) Standard Deduction — flat 30% of NAV(XXX)
  (b) Interest on borrowed capital(XXX)(XXX)

## Determining GAV — the 3-step approach

### Step 1 — Expected Rent (ER)

```

ER = Higher of (Fair Rent, Municipal Value), but RESTRICTED to Standard Rent

```

  • Fair Rent (FR): rent a similar property in the same locality would fetch.
  • Municipal Value (MV): value assessed by municipal authorities.
  • Standard Rent (SR): ceiling set under the Rent Control Act — ER can never exceed SR.
  • ER is computed for 12 months. Exception: if the property is purchased/constructed/sold during the year, ER is taken only for the period of existence and ownership (existence judged from the completion certificate).

### Step 2 — Actual Rent Received

```

Actual Rent Receivable (rent p.m. × months let out)

Less: Unrealised Rent (Rule 4)

= Actual Rent Received

```

### Step 3 — Gross Annual Value

Case 1 — Section 23(1)(c): Actual rent is lower than ER ONLY because of vacancy

  • First, recompute actual rent as if there were no vacancy (add back the vacancy-period rent).
  • If that rent-without-vacancy is higher than ER, then the loss is purely due to vacancy, and GAV = Actual Rent Received (Step 2) — the vacancy benefit is preserved.

Case 2 — Section 23(1)(b): Actual rent (even without vacancy) is STILL lower than ER

  • Here the shortfall is not due to vacancy.
  • GAV = higher of Step 1 (ER) or Step 2 (Actual Rent).

## From GAV to NAV — Municipal Taxes

ParticularsAmount
Gross Annual ValueXXXX
Less: Municipal taxes paid(XXX)
Net Annual ValueXXXX

Municipal taxes rules:

  • Deductible only if actually paid by the owner during the relevant PY (cash basis).
  • If the tenant bears municipal taxes → no deduction for the owner.
  • Taxes on a property outside India are also deductible if that property is chargeable u/s 23.

Unrealised Rent (Rule 4) — deductible from Actual Rent Receivable only if all conditions are met:

1. Tenancy is bona fide.

2. The defaulting tenant has vacated or steps have been taken to evict.

3. The tenant does not occupy any other property of the assessee.

4. Reasonable steps have been taken to recover the rent (legal proceedings if practical).

Worked example

### Example 1

Section 23(1)(c) — loss only due to vacancy: MV ₹1,20,000; FR ₹1,30,000; SR ₹1,25,000. Rent ₹12,000 p.m.; property let for 10 months and vacant 2 months.

Step 1 ER = higher of FR/MV (₹1,30,000) restricted to SR ₹1,25,000 → ER = ₹1,25,000.

Step 2 Actual rent received = 12,000 × 10 = ₹1,20,000.

Rent without vacancy = 12,000 × 12 = ₹1,44,000, which is HIGHER than ER ₹1,25,000 → shortfall is only due to vacancy → Section 23(1)(c) applies → GAV = ₹1,20,000.

### Example 2

Section 23(1)(b) — low rent not due to vacancy: ER (Step 1) = ₹1,25,000. Property let for the full 12 months at ₹9,000 p.m. → Actual rent = ₹1,08,000. No vacancy; actual rent is below ER for reasons other than vacancy → GAV = higher of ER (₹1,25,000) or Actual (₹1,08,000) = ₹1,25,000.

⚠️ Common exam mistakes

  • Letting Expected Rent exceed the Standard Rent — ER is always capped at SR under the Rent Control Act.
  • Deducting municipal taxes on an accrual/payable basis — only taxes ACTUALLY PAID by the owner in the PY are allowed (cash basis); tenant-borne taxes get no deduction.
  • Computing ER for only the let-out months in a part-year-let situation — ER is taken for 12 months (full year) unless the property itself did not exist/was not owned for the full year.
  • Allowing the GAV to be reduced below ER when the shortfall is NOT caused by vacancy — Section 23(1)(c) relief applies only when the low rent is purely due to vacancy.
  • Claiming unrealised rent deduction without satisfying all four Rule 4 conditions (bona fide tenancy, vacated/eviction steps, no other property occupied, reasonable recovery steps).
