Two Tax Deductions, Very Different Rules
A home loan gives you deductions under two separate sections of the Income Tax Act. Getting both right can save ₹1.5–2.5 lakhs annually for a buyer in the 30% tax bracket.
Section 80C: Principal Repayment Deduction
Under Section 80C, the principal component of your home loan EMI is deductible up to ₹1.5 lakh per year. This is part of the combined ₹1.5 lakh Section 80C limit (which also covers EPF, PPF, ELSS, life insurance premium, etc.).
**Key rules:**
Section 24(b): Interest Deduction
Under Section 24(b), the interest component of your home loan EMI is deductible:
This is the bigger deduction for high-ticket loans. On a ₹50 lakh home loan at 9%, annual interest in the first year is approximately ₹4.5 lakhs. You can deduct ₹2 lakhs for a self-occupied property — saving ₹60,000 in tax at 30% bracket.
Plot Loan: Limited Tax Benefit
A plot-only loan (before construction) does NOT get Section 24(b) interest deduction. The deduction is only available once construction is complete and a completion certificate is obtained.
Section 80C principal repayment deduction is also not available on a plot-only loan.
Strategy: Complete your construction and convert to a home loan as quickly as feasible to unlock both deductions.
The First-Time Buyer Additional Benefit
Section 80EEA (applicable to loans sanctioned before 31 March 2022 — check if extended in recent budget): Additional ₹1.5 lakh deduction on interest for first-time buyers if property value is below ₹45 lakhs. Combined with Section 24(b), total interest deduction could be ₹3.5 lakhs for qualifying buyers.
Joint Loan: Double the Benefits
For a joint home loan with a spouse where both are co-owners: each co-owner can claim the Section 80C and 24(b) benefits individually, effectively doubling the deductions. A couple filing separately can together claim ₹3 lakhs in 80C (₹1.5L each) and ₹4 lakhs in 24(b) (₹2L each) — saving ₹2.1 lakhs in tax annually at 30% combined bracket.
