Home loan tax breaks split into two ideas: repayment of principal (potentially under Section 80C within an overall ₹1.5 lakh bouquet shared with PF, ELSS, etc.) and interest paid on a housing loan (Section 24(b) for self-occupied property up to stated limits, with rules for let-out property differing).
Section 24(b) traditionally offers a meaningful deduction for interest on loans for acquisition or construction, subject to conditions like completion within timelines and certification from the lender. Let-out property treatment changed in recent years; verify the current year’s rules because Finance Acts amend deemed rental income and loss set-off limits.
First-time buyers should also explore additional deduction sections introduced in specific years for affordable housing — these have ₹ thresholds on stamp duty value and loan sanction dates. Missing the sanction window by weeks can forfeit the benefit forever for that loan.
Joint owners can optimize by splitting EMI payments and registration proportions to match income slabs, but banks and sale deeds must reflect the same ownership share. Ad-hoc transfers between spouses without documentation will not satisfy assessing officers.
Do not assume the entire EMI is deductible: principal and interest components change every month in an amortization schedule. Your provisional interest certificate from the lender is the starting point; reconcile with Form 16 and 26AS before filing. Always revalidate each assessment year — this is one of the most amended parts of tax law.
