How home loan tax benefits stack

Under the old tax regime, your home loan EMI gives you two distinct tax breaks:

  • Section 71 (formerly 24(b)) - interest paid is deductible up to ₹2,00,000 per year for a self-occupied property. For a let-out property, there is no upper limit (but the set-off against other heads is capped at ₹2 lakh; balance carried forward).
  • Section 123 (formerly 80C) - principal repayment is deductible up to ₹1,50,000 per year. This is part of the overall ₹1.5 lakh 80C cap, not in addition to it.

What about the new tax regime?

Under the new tax regime (Section 202, default from FY 2026-27), Section 71 (24(b)) is not available for self-occupied property. For let-out property, interest is still set-off against rental income. Section 123 is also unavailable in the new regime.

FAQs

How is home loan EMI calculated?

EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual / 12), and n is the tenure in months.

How much of my EMI is tax-deductible?

The interest component is deductible under Section 71 (formerly Section 24(b)) up to ₹2,00,000 per year for self-occupied property. The principal repayment is deductible under Section 123 (formerly 80C), up to ₹1.5 lakh combined cap with other 80C investments.
