## Deductions from Net Annual Value — Section 24
Only two deductions are allowed from NAV. No other expense (insurance, ground rent, collection charges, etc.) is deductible.
### (a) Standard Deduction — 30% of NAV [Section 24(a)]
- A flat 30% of NAV, allowed for repairs/maintenance irrespective of actual expenditure.
- If NAV = 0 (e.g. an SOP), the 30% deduction is also NIL.
- If part of the property is used for business/profession, the attributable actual expenses are claimed under PGBP instead.
### (b) Interest on Borrowed Capital [Section 24(b)]
- Loan may be borrowed from any person.
- Interest is allowed on an accrual basis for acquisition, construction, repairs, renewal or reconstruction.
- A fresh loan to repay an original loan (used for the above) — interest on it is also deductible.
- Interest on late payment of interest is NOT deductible.
- If the sale price is payable in installments with interest to the seller, the unpaid price is treated as capital borrowed, and that interest qualifies u/s 24.
Interest has two components:
```
Total Interest = Pre-Construction Period Interest (PCPI) + Current Year Interest (CYI)
```
Pre-Construction Period Interest (PCPI):
- Pre-Construction Period (PCP) = from the date the loan is borrowed up to the end of the FY immediately preceding the FY in which construction is completed.
- PCPI is allowed in 5 equal annual installments, beginning in the PY in which the property is acquired/construction completed.
- If the date of borrowing and date of completion fall in the same FY, PCPI = Nil.
Current Year Interest (CYI):
- Interest from the year the construction is completed / property acquired — fully deductible in that very year.

## Interest Deduction Limits for SOP/UOP
### Under the Default (new) Tax Regime
- NO interest deduction for an SOP/UOP when the NAV = 0 benefit is claimed.
- No restriction on interest for LOP / DLOP.
### Under the Optional (old) Tax Regime — for SOP/UOP with NAV = 0
| Purpose of loan | Maximum deduction |
|---|---|
| Construction or Acquisition — subject to: (1) loan borrowed on or after 1/4/1999, and (2) construction/acquisition completed within 5 years from the end of the FY of borrowing | Lower of Total Interest or ₹2,00,000 |
| Other purposes (repairs, renovation, reconstruction) | Lower of Total Interest or ₹30,000 |
- These ceilings are per assessee, NOT per property.
- No limit applies to LOP / DLOP — full interest is deductible there.
