Deductions from NAV under Section 24 — standard deduction and interest on borrowed capital (with regime-wise SOP limits)

## 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 loanMaximum 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 borrowingLower 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.

Worked example

### Example 1

PCPI computation: Loan of ₹20,00,000 taken on 1 July 2021 at 10% p.a.; construction completed and property occupied as SOP on 15 September 2024.

Pre-construction period = 1 July 2021 to 31 March 2024 (end of FY preceding the FY of completion).

Interest for that period = ₹20,00,000 × 10% × (33/12 years) = ₹5,50,000.

PCPI allowed = ₹5,50,000 ÷ 5 = ₹1,10,000 per year for 5 years starting FY 2024-25.

Current year interest for FY 2024-25 (full year) = ₹2,00,000.

Total interest FY 2024-25 = ₹1,10,000 + ₹2,00,000 = ₹3,10,000.

Under the OLD regime for a self-occupied house (acquisition loan, completed within 5 years), deduction is capped at ₹2,00,000. Under the DEFAULT regime, no interest deduction for an SOP. If instead this were a LOP/DLOP, the full ₹3,10,000 would be allowed.

### Example 2

₹30,000 ceiling: A loan was taken for renovation (not construction/acquisition) of a self-occupied house; interest for the year is ₹45,000. Under the optional regime the deduction is restricted to ₹30,000.

⚠️ Common exam mistakes

  • Claiming the 30% standard deduction on a self-occupied house with NAV = 0 — 30% of zero is zero.
  • Deducting interest on a self-occupied house under the DEFAULT regime — interest on SOP/UOP is not allowed there; only LOP/DLOP interest survives.
  • Applying the ₹2,00,000 / ₹30,000 ceiling per property — the limit is per ASSESSEE across all eligible properties.
  • Forgetting that for the ₹2,00,000 limit the construction/acquisition must be completed within 5 years from the end of the FY of borrowing and the loan must be on or after 1/4/1999 — otherwise the limit drops to ₹30,000.
  • Including PCPI when the loan was borrowed and construction completed in the same financial year — PCPI is Nil in that case.
  • Deducting interest on late payment of interest, or restricting interest of a LOP/DLOP to ₹2,00,000 — neither is correct.
