Tax season rolls around and suddenly every loan you’re repaying starts looking like a potential deduction, whether or not that’s actually true. 

Two types of borrowing get lumped together in this confusion more than most, mainly because people assume any interest paid toward any loan should count for something on the tax return. It doesn’t work quite that simply, and the gap between the two is bigger than most borrowers expect.

Why Do People Assume Both Work the Same Way at Tax Time?

Mostly because interest is interest, in a loose sense, and it feels reasonable to expect similar treatment across the board. 

Tax rules don’t actually work off that logic though. What gets deducted depends entirely on what the money was used for and how clearly that purpose can be shown, not simply on the fact that interest was paid at all.

What Deduction Does a Home Loan Actually Offer?

A fairly generous one, historically. A home loan typically allows the interest portion to be claimed as a deduction under Section 22 of the Income Tax Act, 2025, set off against income from house property.

The principal repaid counts toward a separate deduction under Section 123 of the same act, provided you’re filing under the old tax regime that still recognizes these benefits. 

This is the reason home loans are so often discussed alongside tax planning in the first place.

Does This Benefit Apply No Matter Which Tax Regime You Pick?

No, and this is where a lot of people trip up. The new tax regime, now the default option most taxpayers fall into unless they actively choose otherwise, does away with several deductions that used to be standard, including the Section 22 interest benefit on a self-occupied property. 

The old tax regime still recognizes it, but only if you specifically opt into that structure while filing. Assuming the deduction applies automatically, regardless of which regime you’ve picked, is one of the most common mistakes people make here.

Where Does Principal Repayment Fit Into the Picture?

Separately from the interest benefit. Principal repaid toward the loan can be claimed under Section 123, again only under the old tax regime, and it sits within a broader combined limit shared with a handful of other savings and investment options.

Someone already using up that combined limit through other instruments might find the actual benefit from principal repayment smaller than expected.

Does a Personal Loan Ever Qualify for a Deduction?

Occasionally, yes, though not with the same automatic benefit that comes built into borrowing meant specifically for a house. A personal loan is generally treated as having no defined purpose as far as tax rules are concerned, which usually rules out any deduction entirely. 

The exception shows up when the borrowed amount can be clearly traced to a specific qualifying use, most commonly toward buying, constructing, or renovating a house, where the interest portion can then be claimed under Section 22 just as it would be otherwise, or toward a genuine business expense, deductible under the ordinary rules that apply to business costs.

What Would You Actually Need to Claim That Exception?

Solid proof, mainly. Simply saying the money went toward home repairs isn’t enough on its own. Bank statements, invoices from contractors, and a clear paper trail connecting the loan amount to the actual expense are usually necessary before a claim like this holds up.

Without that documentation, the deduction is unlikely to survive scrutiny even if the money genuinely was used that way.

Where the Two Genuinely Differ Here

One type of borrowing comes with a built-in tax benefit baked into the product itself, provided the right regime is chosen. The other requires you to actively prove a specific use before any benefit becomes available at all, and even then, the claim rests entirely on documentation rather than the nature of the loan. 

Treating both as equally deduction-friendly is where the real confusion starts.

Mistakes People Make Assuming Blanket Tax Benefits

• A lot of borrowers assume any loan repayment automatically reduces their tax bill, without checking which regime they’ve actually selected or whether the specific deduction still applies to them. 
• Some assume a personal loan used for a wedding or a vacation somehow qualifies simply because the funds eventually touched household expenses. 
• Others fail to keep any paperwork tracing how a personal loan was actually spent, then find themselves unable to support a claim they were confident about. 
• And plenty never revisit which regime suits them best, sticking with a default choice purely out of habit rather than an actual comparison.

The Simple Way to Think About This

One of these loans was built with a tax benefit in mind, though only under a specific set of rules you have to actively choose. The other offers nothing by default, and only occasionally earns a deduction when the purpose can be proven beyond doubt. 

Checking which regime you’re actually under, and keeping proper records regardless of which loan you’re repaying, matters far more than assuming either one automatically works in your favor.
