Home Loan Tax Benefit in the New Regime vs Old: ₹50 Lakh Loan, Year by Year

Nirav and Hetal picked up the keys to their 2BHK in Surat's Vesu area a week before Diwali. Joint loan of ₹50 lakh, 20 years, 8.5%, EMI ₹43,391 a month. The bank's sales executive had said it twice while they signed: "Tax benefit bhi milega, sir." In January, Nirav's HR portal asked him to pick old or new regime, and he realised nobody had told him what that benefit actually is, or whether it exists at all for someone filing in the new regime.

Here's the honest version, worked out on the site's calculators for exactly their loan. The old regime gives a deduction on interest and principal. The new regime gives nothing on a house you live in, and something on a house you rent out. And for most salaried people, even the full old-regime benefit doesn't make the old regime cheaper. The numbers below show where that line falls, and what changes when the loan is joint, the flat is let out, or the building is still under construction.

What a ₹50 lakh loan pays in interest, year by year

The tax rules treat interest and principal separately, so start with how much of each you pay in a year. On the home loan EMI calculator, ₹50 lakh at 8.5% for 20 years gives an EMI of ₹43,391, which is ₹5,20,694 a year. The split moves every year:

Assumptions: ₹50 lakh, 8.5% fixed for the whole term, 20 years, EMI from the first month. Over 20 years the interest adds up to ₹54,13,879, of which only ₹34,83,494 fits under the ₹2 lakh yearly cap. The other ₹19,30,385 gets no tax treatment in either regime.

About the 8.5%. On 7 October 2026 the RBI raised the repo rate by 0.25% to 5.50%, as per Business Today's report. On the same day the cheapest public sector bank home loans started at 7.0% to 7.35% for the best credit scores, with revisions expected after the hike. A couple with ordinary scores at a private bank lands closer to 8–8.5%, so that's the rate used here. The EMI side is covered in ₹50 lakh home loan EMI. This post is only about the tax.

What the old regime allows

From 1 April 2026 the Income-tax Act 2025 is in force. The familiar section numbers have changed, the rules haven't. The links below go to sites that reproduce the section text.

Interest: section 22, old 24(b)

For a self-occupied house, section 22 of the new Act allows the loan interest up to ₹2,00,000 a year, on two conditions: the house is bought or built within five years from the end of the tax year of borrowing (otherwise the cap drops to ₹30,000), and the lender certifies the interest. Nirav and Hetal's year-one interest is ₹4,21,182, so ₹2 lakh is the most this loan can claim in a year, and that stays true till year 14.

Principal: section 123, old 80C

The principal part of the EMI goes into the ₹1.5 lakh basket of section 123, shared with EPF, PPF, LIC premiums and ELSS. Stamp duty and registration also count, only in the year you pay them, inside the same ₹1.5 lakh. On a ₹62.5 lakh flat (₹50 lakh is 80% of it) stamp duty and registration cross ₹3 lakh in most states, so the cap is full in that one year on its own. After that it's the principal: ₹99,511 in year one, ₹1,39,641 in year five, above ₹1.5 lakh by itself from year six. Add a normal EPF deduction and the basket is full by year three or four.

80EEA: not for a loan taken now

Section 80EEA, now section 131, gave another ₹1.5 lakh of interest on a first house with a stamp duty value up to ₹45 lakh. It applies only to loans sanctioned between 1 April 2019 and 31 March 2022, as ClearTax's page on 80EEA also notes. A loan sanctioned in 2026 gets nothing from it.

What the new regime allows: nothing on your own house

The new regime is the default, and section 202 of the Income-tax Act 2025 (old 115BAC) lists what it switches off. Three items on that list matter for a home loan:

• The interest deduction of section 22(1)(b) for a self-occupied house. So the ₹2 lakh is gone.
• The deductions of Chapter VIII, which includes section 123. So the principal and stamp duty get nothing.
• Set-off of a loss under "income from house property" against any other head. So a loss on a let-out house can't reduce your salary income.

For a house you live in, that's the whole story: zero tax benefit. What you get in exchange is lower slab rates and a ₹75,000 standard deduction against the old regime's ₹50,000. Whether that exchange is good for you is what the next two sections work out.

For a house you rent out, there is still something. The interest is a deduction while working out the rental income under section 22, and that part is not switched off. Rent comes in, the 30% standard deduction and the full interest go out, and if the result is zero or negative the rent is untaxed. The loss just can't go further than that.

Tax saved in the old regime, year by year, for a 30% slab earner

Nirav earns ₹15 lakh a year. In the old regime, after the ₹50,000 standard deduction, his taxable income is ₹14.5 lakh, in the 30% slab (31.2% with cess). Every ₹1 of deduction saves him 31.2 paise. Say he already fills ₹1.5 lakh of section 123 with EPF and PPF, and pays ₹25,000 for health insurance. The income tax calculator gives his old regime tax without the loan as ₹2,02,800. With the loan's interest added:

Assumptions: salary ₹15 lakh every year (kept flat so the loan's effect shows), below 60, section 123 full at ₹1.5 lakh, ₹25,000 health insurance, FY 2026-27 slabs. New regime tax on the same salary: ₹97,500.

Two things jump out. The loan saves Nirav ₹62,400 a year for fourteen years and ₹10,86,860 over the full twenty, which is real money. And yet his old regime bill is still ₹42,900 higher than the new regime in every one of those years. The cheaper new slabs are worth more to him than the ₹2 lakh deduction, even with his section 123 basket full. The bank executive was right that the benefit exists, and wrong to suggest it matters to Nirav.

At ₹20 lakh the gap is wider, not narrower: ₹2,96,400 in the old regime with the same deductions and the full ₹2 lakh of interest, against ₹1,92,400 in the new. Higher income doesn't rescue the old regime. Only more deductions do.

The full tax at ₹8 to ₹25 lakh of salary in both regimes is in tax on salary from ₹8 to ₹25 lakh, and why salary up to ₹12.75 lakh pays nothing in the new regime is in zero tax up to ₹12 lakh.

Break-even: how much in deductions the old regime needs

So when does the loan tip it? Only when it's one of several large deductions. Here are the total deductions (over and above the standard deduction) at which the old regime's tax equals the new regime's, from the income tax calculator:

Assumptions: salaried, below 60, FY 2026-27 slabs, no surcharge. Deductions means everything in the old regime together: section 123, health insurance, NPS, HRA, home loan interest and so on. Below ₹12 lakh the new regime's tax is zero because of the rebate, so there's nothing to break even against.

A home loan brings at most ₹3.5 lakh to this pile: ₹2 lakh of interest and ₹1.5 lakh of principal (the principal only if nothing else is in section 123). Add ₹25,000 of health insurance and the extra ₹50,000 NPS deduction and Nirav reaches ₹4.25 lakh, still ₹1.19 lakh short at ₹15 lakh of salary. The calculator shows his old regime tax at ₹1,24,800 against ₹97,500 new. The deduction that usually closes the gap is HRA, and someone living in the house they just bought doesn't get it. Nirav's colleague, who bought in Surat but works in Ahmedabad on weekdays and pays ₹10,000 rent there, does: with ₹1.2 lakh of HRA on top, the old regime comes to ₹97,240, ₹260 less than new. A tie.

The clean rule: a home loan alone never makes the old regime win for a salaried person. It wins only when the loan sits next to HRA or a pile of other deductions. Run both regimes with your own numbers on the income tax calculator, and see new vs old tax regime for FY 2026-27 for the break-even at every income, without a home loan in the picture.

If the flat is rented out: the one case the new regime helps

Say Nirav and Hetal keep living with his parents and let the Vesu flat out for ₹15,000 a month. The house property calculation, under either regime, is:

Assumptions: rent ₹15,000 a month for 12 months, municipal tax ignored, year-one interest from the schedule above. The interest has no ₹2 lakh ceiling here. The ceiling is on the loss you can use.

Old regime: section 109 (old 71(3A)) lets ₹2,00,000 of this loss be set off against salary in the same year. The remaining ₹95,182 is carried forward under section 110, for up to eight years, but only against future rental income. Nirav's tax at ₹15 lakh with the ₹2 lakh set-off comes to ₹1,40,400, the same as the self-occupied case, with the rent itself untaxed on top.

New regime: the rent is still wiped out by the standard deduction and interest, so the ₹1.8 lakh comes in tax-free. That's the benefit. The ₹2,95,182 loss can't touch his salary, and his tax stays at ₹97,500. Whether the unused loss can be carried forward against future rent in the new regime is read differently by different practitioners, so ask your CA before counting on it. Either way, ₹97,500 beats ₹1,40,400 for Nirav, let out or not.

Joint loan: both can claim, but each picks their own regime

The flat is in both names and both are borrowers, which is the condition for both to claim. As this May 2026 note on Taxguru explains, each co-owner who is also a co-borrower claims their share of the interest up to their own ₹2 lakh, and of the principal under their own ₹1.5 lakh. Share means the ownership share in the registered deed, and the money must actually go from their own or a joint account.

At 50:50, year-one interest of ₹4,21,182 splits into ₹2,10,591 each, so both can claim the full ₹2 lakh, and principal of ₹99,511 splits into ₹49,756 each. On paper the couple can deduct ₹4 lakh of interest a year instead of ₹2 lakh, which is why CAs like joint loans.

The catch is that the regime choice is per person. Hetal earns ₹12 lakh. In the new regime her tax is ₹0, because the rebate covers taxable income up to ₹12 lakh. In the old regime, even with her basket full, ₹25,000 of health insurance and her ₹2 lakh of interest, she pays ₹70,200. Her share of the loan is worth nothing to her, and it can't be transferred to Nirav. A joint loan doubles the deduction only when both earners can use the old regime, which in practice means both well above ₹15 lakh with HRA or other big deductions. And if the loan is joint but the flat is in one name, only the owner can claim.

Under-construction flat: interest in five instalments

Suppose the Vesu building wasn't ready and possession came in March 2028, two years after the loan started. Interest paid before the year of possession is called pre-construction (or prior period) interest. Section 22 lets you claim it in five equal instalments starting from the year the house is completed. On this loan that's ₹4,21,182 plus ₹4,12,387, which is ₹8,33,569, so ₹1,66,714 a year for five years.

It sounds like a bonus, and for a let-out house it is. For a self-occupied house it's mostly on paper, because the ₹2 lakh cap covers that year's interest and the instalment together. In year three the regular interest alone is ₹4,02,813, twice the cap, so the ₹1,66,714 instalment gets nothing. On a ₹50 lakh loan the regular interest only drops below ₹2 lakh in year 15, and the five instalments are long over by then. On a smaller loan, where yearly interest is under the cap, the instalments do get used.

Two more rules. If construction isn't finished within five years from the end of the tax year of borrowing, the cap falls from ₹2 lakh to ₹30,000, which has caught many people in stalled projects. And nothing can be claimed until the year of completion, even in the old regime, even though the pre-EMIs go out every month.

What to keep: the interest certificate and three other papers

In January HR asks for proof of what you declared. For a home loan the main document is the interest certificate, which every bank and housing finance company gives from net banking or the app, usually under Loans, then Certificates or Tax Services. As this September 2026 note from Ujjivan Small Finance Bank describes, the provisional certificate shows the interest and principal you're expected to pay in the current year, and the final one, issued after 31 March, shows what you actually paid. Give HR the provisional one in January and use the final one for the return in July.

Keep three other things safe: the possession or completion letter from the builder (it fixes the year from which you can claim), the sale deed showing the ownership shares (it fixes who claims what), and the stamp duty and registration receipts (for section 123 in the year of purchase). For a joint loan, get the certificate with both names on it.

In the new regime you still need the certificate for one thing: a let-out house, where the interest goes into the house property schedule of the return.

What Nirav and Hetal ended up doing

Nirav stayed in the new regime. The loan deduction would have saved him ₹62,400 a year, and the old regime would still have cost ₹42,900 more after counting it. Hetal stayed in the new regime because her tax is zero there. They kept the joint loan for the bigger sanction and the clean ownership record, not for the tax.

What they did instead was look at the interest itself. Year one's ₹4,21,182 is the real cost, and no regime touches ₹2.21 lakh of it. A prepayment from Nirav's Diwali bonus, applied to the tenure, cuts more interest than any deduction. The post on prepaying to reduce EMI or tenure has those numbers. And prepaying doesn't waste the ₹2 lakh deduction until yearly interest falls below ₹2 lakh, which on this loan takes till year 15.

The decision isn't permanent either. A salaried person without business income picks the regime fresh every year in the return. So check each January, interest certificate in hand, both regimes side by side on the income tax calculator. The year your loan interest, HRA and other deductions together cross the break-even line for your salary is the year you switch. For a ₹15 lakh salary that line is ₹5.44 lakh. The loan gets you a little more than halfway.
