When a property is partly self-occupied (SOP) and partly let out (LOP), the Income Tax Act treats it as two separate properties for computation purposes.
Step-by-Step Calculation
- Segregate the Property into Two Parts
- Self-Occupied Portion (SOP)→ Treated as one house property.
- Let-Out Portion (LOP)→ Treated as another house property.
- Compute Income for Each Portion Separately
(A) Self-Occupied Portion (SOP)
- Annual Value (AV)= Nil (since it is self-occupied).
- Deduction under Section 24(b):
- Interest on housing loan (if any) → Maximum ₹2 lakh(if loan taken after 1-4-1999).
- Taxable Income from SOP= 0 – Interest Deduction = Negative value allowed (loss).
(B) Let-Out Portion (LOP)
- Gross Annual Value (GAV)= Higher of:
- Actual Rent Received(for let-out portion).
- Expected Rent(Municipal Value / Fair Rent / Standard Rent, whichever is lower) proportionate to let-out area.
- Less: Municipal Taxes(if paid, proportionate to let-out portion).
- Net Annual Value (NAV)= GAV – Municipal Taxes.
- Deductions under Section 24:
- Standard Deduction= 30% of NAV.
- Interest on Housing Loan(proportionate to let-out portion) → No upper limit.
- Taxable Income from LOP= NAV – (Standard Deduction + Interest).
- Final Income from House Property
= Taxable Income from SOP (usually negative) + Taxable Income from LOP.
Example Calculation
Facts:
- A property has 60% self-occupiedand 40% let out.
- Municipal Value (MV)= ₹3,00,000 (Full Year).
- Fair Rent (FR)= ₹3,60,000 (Full Year).
- Standard Rent (SR)= ₹3,30,000 (Full Year).
- Actual Rent Received (Let-out portion)= ₹12,000/month (₹1,44,000/year).
- Municipal Taxes Paid= ₹20,000 (Full Year).
- Home Loan Interest= ₹2,50,000 (Full Year).
Step 1: Compute for Let-Out Portion (40%)
- Expected Rent= Lower of (MV, FR, SR) = ₹3,00,000 (MV).
- Proportionate Expected Rent (40%)= ₹1,20,000.
- Actual Rent (40%)= ₹1,44,000.
- Gross Annual Value (GAV)= Higher of (₹1,20,000 or ₹1,44,000) = ₹1,44,000.
- Less: Municipal Taxes (40%)= ₹8,000.
- Net Annual Value (NAV)= ₹1,44,000 – ₹8,000 = ₹1,36,000.
- Deductions:
- Standard Deduction (30% of NAV)= ₹40,800.
- Interest on Loan (40% of ₹2,50,000)= ₹1,00,000.
- Taxable Income (LOP)= ₹1,36,000 – (₹40,800 + ₹1,00,000) = ₹(4,800) [Loss].
Step 2: Compute for Self-Occupied Portion (60%)
- Annual Value= Nil.
- Interest on Loan (60% of ₹2,50,000)= ₹1,50,000.
- Deduction Allowed (Max ₹2 lakh)= ₹1,50,000 (fully allowed).
- Taxable Income (SOP)= 0 – ₹1,50,000 = ₹(1,50,000) [Loss].
Step 3: Final Income from House Property
= Loss from SOP (₹-1,50,000) + Loss from LOP (₹-4,800)
= Total Loss = ₹(1,54,800)
This loss can be adjusted against other heads of income (up to ₹2 lakh per year under Section 71).
Key Points to Remember
- Proportionate Calculation: All values (rent, municipal taxes, interest) must be split as per the let-out and self-occupied ratio.
- Interest Deduction Cap:
- SOP: Max ₹2 lakh (if loan taken after 1-4-1999).
- LOP: No limit.
- Loss Adjustment: Loss from house property can be set off against other income (salary/business).
