Sub-clause (b) of section 24 read with the second proviso, and section 26 of the Income-tax Act, 1961 -- the per-co-owner ₹2 lakh cap; the requirement of definite and ascertainable shares; the contribution-based allocation; the practitioner's structuring of joint title plus joint loan plus joint EMI; and the Income Tax Appellate Tribunal jurisprudence on partial-EMI and single-EMI joint-ownership scenarios
Taxpayer Brief
Where a husband and wife jointly own a residential property and have jointly taken the home loan, each spouse can independently claim the section 24(b) interest deduction up to ₹2 lakh -- producing an aggregate family deduction of ₹4 lakh. The effective tax saving on a ₹4 lakh deduction at the 30%-plus-cess slab is approximately ₹1.25 lakh per year. Maximising this is one of the most lucrative tax-planning levers available to dual-income salaried families. The conditions are precise -- joint title with definite shares, joint loan, contribution-based EMI payment, separate documentation. This article maps the framework, the common structures, the partial-payment contingencies, and the practitioner's checklist.
Complexity Matrix
Feature | Complexity Level | Primary Risk |
|---|---|---|
Joint title 50:50, joint loan, joint EMI 50:50 | Low | Each spouse claims ₹2 lakh; aggregate ₹4 lakh |
Joint title 50:50, joint loan, single-spouse EMI | Medium | Income Tax Appellate Tribunal authority required for full claim by EMI-payer |
Unequal joint title (e.g., 70:30), joint loan, allocation by share | High | Section 24(b) follows ownership share; documentation critical |
Joint title with parents / siblings; multiple co-owners | Very High | Per-owner ₹2 lakh; aggregate up to ₹6L+; complex contribution mapping |
1. The Statutory Framework
Provision | Effect |
|---|---|
Section 26 of the Income-tax Act, 1961 | Where property is owned by two or more persons and their respective shares are definite and ascertainable, each co-owner is taxed individually on the portion of income attributable to his / her share |
Sub-clause (b) of section 24 | Interest on loan for property is deductible from House Property income; capped at ₹2 lakh for self-occupied property |
Second proviso to sub-clause (b) of section 24 | The ₹2 lakh cap applies per assessee (per co-owner), not per property |
The ₹2 lakh cap is per assessee, not per property This is the critical statutory point. Where a property is jointly owned by two persons (typically spouses), the ₹2 lakh cap is available to EACH of them separately. A property with joint title and joint loan can therefore support a combined ₹4 lakh interest deduction at the family level. With three co-owners, ₹6 lakh; with four, ₹8 lakh. Each co-owner files his / her own Income Tax Return claiming his / her own share of the deduction. |
2. The Three Conditions for the Per-Co-Owner Claim
Condition | Test | Documentation |
|---|---|---|
1. Joint Title with Definite Shares | Sale deed registers each co-owner's specific percentage share -- e.g., 50:50, 70:30, 25:25:25:25 | Sale deed; share-of-ownership clause |
2. Joint Loan | Both / all co-owners are co-borrowers on the loan agreement | Loan sanction letter; loan agreement |
3. Contribution-Based EMI Payment | Each co-owner pays his / her share of the EMI, ideally from his / her own bank account | Bank statement showing EMI debits by each spouse / co-owner |
Partial-EMI scenarios Where co-owners hold the property in definite and ascertainable shares, section 26 of the Income-tax Act, 1961 requires each co-owner's share of the income from the property to be computed under sections 22 to 25 and included in that co-owner's own total income, so each co-owner claims the section 24(b) deduction in computing his or her own share. Where the EMI is paid wholly from one spouse's account, the statute does not say how the interest is to be divided between co-borrowers; the outcome turns on the facts and the documents (gift, contribution, or family-financing agreement). The cleanest structure remains contribution-based EMI -- each spouse paying his / her own share. |
3. Worked Example -- Dual-Income Couple in Bangalore
Mr. Vikram (₹35 lakh annual salary) and Mrs. Asha (₹30 lakh annual salary) jointly purchased a 3 BHK apartment in Bangalore for ₹1.5 crore in April 2023. Both are 50:50 co-owners. Joint home loan of ₹1.2 crore at 8.5% annual interest; EMI ₹1,04,000 per month, paid 50:50 from each spouse's salary account. Annual interest in Tax Year 2026-27 (year 4 of the loan) -- approximately ₹9.6 lakh.
Per-Spouse Computation | Mr. Vikram | Mrs. Asha |
|---|---|---|
Share of total interest paid -- 50% of ₹9.6 lakh | ₹4,80,000 | ₹4,80,000 |
Section 24(b) cap for self-occupied property | ₹2,00,000 | ₹2,00,000 |
Allowable section 24(b) deduction | ₹2,00,000 | ₹2,00,000 |
Tax saved at 30% slab + 4% Cess (each spouse) | ₹62,400 | ₹62,400 |
Combined family tax saving | ₹1,24,800 | (same) |
Without joint structure -- single-owner alternative Had Mr. Vikram alone been the title-holder and sole borrower, his deduction would have been capped at ₹2 lakh -- and the additional ₹2.8 lakh of interest paid (his share of ₹4.8 lakh minus the ₹2 lakh cap) would have been wasted from a tax perspective. The joint structure preserves the full benefit. The structuring decision must be made at the time of purchase -- joint title cannot be retrofitted to convert single-owned property to joint without triggering section 56(2)(x) gift implications. |
4. Unequal Share Scenario
Where the joint title shows unequal shares (e.g., 70:30 between spouses), the section 24(b) deduction must be allocated in the same ratio. Each co-owner can claim up to ₹2 lakh, BUT only on his / her share of the actual interest. If the 30%-share spouse's allocated interest is only ₹1.5 lakh, that is the ceiling of his / her claim -- the unused ₹50,000 of the ₹2 lakh cap cannot be transferred to the other spouse.
5. Multi-Co-Owner Structures
Co-Owner Profile | Aggregate Section 24(b) Cap |
|---|---|
2 co-owners (typical spouse case) | ₹4 lakh |
3 co-owners (parent + spouse + self) | ₹6 lakh |
4 co-owners (parent + spouse + self + sibling) | ₹8 lakh |
Hindu Undivided Family co-ownership with members | Per-member cap; HUF as single owner has its own ₹2 lakh |
The 4+ co-owner caveat Bringing in additional co-owners beyond the spouse pair (parents, siblings, adult children) to inflate the aggregate cap can be structured but invites scrutiny. The assessing officer can challenge whether the additional co-owners genuinely contributed to the purchase consideration and EMI payments. Each additional co-owner should have demonstrable funds-flow evidence supporting their share. Without genuine funds, the co-ownership is a façade. |
6. Section 80EEA / 80EE Layer
The additional ₹50,000 deduction under section 80EE (for first-time buyers, sanction in 2016-17) and the additional ₹1.5 lakh deduction under section 80EEA (for affordable housing, sanction in 2019-20 to 2022-23) are also per-assessee deductions and can be claimed independently by each co-owner subject to the eligibility conditions. HP-09 covers the section 80EEA framework in detail.
7. Practitioner Documentation Discipline
- Sale deed clearly recording each co-owner's percentage share.
- Loan sanction letter naming all co-borrowers.
- Loan agreement -- shareholder-wise interest schedule.
- Bank statement showing EMI debits from each spouse's / co-owner's separate account.
- Annual interest certificate from the lender, ideally with each co-borrower's share separately certified.
- Internal contribution agreement if EMI is paid disproportionate to ownership share -- explaining the contribution arrangement.
- Each co-owner's Income Tax Return claiming his / her share of section 24(b) deduction.
8. Key Takeaways
- Section 26 read with second proviso to section 24(b) -- the ₹2 lakh cap is per co-owner, not per property.
- Three conditions -- joint title with definite shares, joint loan, contribution-based EMI.
- Spouse pair structure produces ₹4 lakh aggregate deduction; family tax saving roughly ₹1.25 lakh per year.
- Mumbai Income Tax Appellate Tribunal accepts partial-EMI scenarios with documentary support of inter-spouse contribution.
- Multi-co-owner structures (3+) can scale aggregate cap; require genuine funds evidence per co-owner.
- Sections 80EE / 80EEA provide additional per-assessee deductions; co-owners can claim independently.
