Home Loan Tax Benefits: Sections 80C and 24(b)
Updated 2026-10-26
A home loan EMI has two parts: principal and interest. Each part has its own tax deduction. On a ₹50 lakh loan, the two together can save about ₹90,000 in tax in the first year if you are in the 30% slab.
The two deductions in plain English
Section 80C covers the principal you repay. You can claim up to ₹1.5 lakh a year, but that limit is shared with other things you may already use, such as your provident fund, life insurance premium and ELSS funds. So if your PF already uses most of the ₹1.5 lakh, the home loan adds little.
Section 24(b) covers the interest you pay on a self-occupied home. You can claim up to ₹2 lakh a year. This limit is separate from 80C, which is why the interest deduction is usually the bigger win.
Stamp duty and registration charges also count under 80C, but only in the year you pay them and only within the same ₹1.5 lakh limit.
Who can claim
You need to be paying the loan yourself and the home should be in your name, fully or partly. The deductions work under the old tax regime. If you choose the new regime, you give up these deductions on a self-occupied home, so it is worth comparing both regimes each year. Joint borrowers who are also co-owners can each claim their own share, up to the limits. That can double the benefit for a couple.
For a home you rent out, the interest deduction is not capped at ₹2 lakh, but the loss you can set against other income is. Rules for under-construction homes are different too. Interest paid before you get possession is claimed in five equal parts starting from the year you move in.
A worked example
Say you borrow ₹50 lakh at 8.5% for 20 years. Your EMI is about ₹43,391 a month, or ₹5.2 lakh a year.
In the first year, about ₹4.21 lakh of what you pay is interest and ₹0.99 lakh is principal. Here is what you can claim:
- Interest under 24(b): the limit is ₹2 lakh, so you claim ₹2,00,000.
- Principal under 80C: you paid ₹99,000, so you claim up to that, assuming you have room under ₹1.5 lakh.
That is about ₹3 lakh of deductions. If you are in the 30% slab, you save roughly ₹90,000 in tax before cess. If you had no other 80C investments and paid the full ₹1.5 lakh of principal in later years, the best case is ₹3.5 lakh of deductions and about ₹1.05 lakh of tax saved in a year.
In the early years your interest is well above the cap. You get no tax benefit on the extra ₹2.21 lakh of interest. So don't let tax savings decide how much you borrow. Each rupee of interest costs you a full rupee, and the deduction returns at most 30 paise of it, up to the cap.
Mistakes to avoid
- Assuming the whole EMI is deductible. Only the principal under 80C and the interest under 24(b), within the limits.
- Forgetting the lender's certificate. Your bank issues an annual statement splitting interest and principal. Keep it for your tax filing.
- Claiming without being an owner. If you are not on the property papers, you cannot claim, even if you pay the EMI.
- Ignoring the regime choice. If your total deductions are small, the new regime's lower slab rates may leave you better off.
Check current rules
Tax rules change, and section numbers may be renumbered under the newer Income-tax Act. The limits above were the standard ones at the time of writing. Check the latest rules or ask a tax professional before you file.
Try it with your own loan
Use our EMI calculator to see how much of your EMI is interest and principal in each year. The year-by-year table gives you the numbers to compare against the ₹2 lakh and ₹1.5 lakh limits. If your interest is far above ₹2 lakh, consider whether a larger down payment or a shorter tenure would save you more than the tax benefit ever will.
