(INDIA) — Indian taxpayers with a Home Loan for property in the country face a stark choice before filing returns for FY 2025-26: the tax benefit many expect depends first on whether they choose the old tax regime or the new tax regime.

Salaried buyers, NRIs investing in Indian homes, returning residents and first-time apartment buyers often assume a housing loan automatically brings large income-tax relief. This assumption can be costly, because principal repayment, interest deduction and even treatment of house-property loss depend on the regime selected and the conditions attached to the property.

The distinction carries extra weight this year because India is in a transition phase in direct taxation. The Income-tax Act, 2025 came into force from April 1, 2026, replacing the older Income-tax Act, 1961 for future tax years, while returns for FY 2025-26, corresponding to AY 2026-27, continue to be filed under the provisions applicable to that year.

That creates two separate questions for filers. One is the statute that governs the year being filed. The other is whether the taxpayer chooses the concessional slab system known as the new tax regime, which restricts several deductions.

Under the old tax regime, the main Home Loan benefits generally sit in two areas. Principal repayment may qualify under section 80C, subject to the overall cap of ₹1.5 lakh, while interest on borrowed capital for a self-occupied house property may be deductible under section 24(b), generally up to ₹2 lakh where conditions are met.

Even that headline figure is not automatic. The commonly discussed combination of up to ₹1.5 lakh under section 80C and up to ₹2 lakh under section 24(b) depends on the nature of the property, the purpose of the loan, completion of construction, ownership, actual payment and the taxpayer choosing the old tax regime.

The section 80C benefit also shares space with other eligible items, including life insurance premium, employee provident fund, public provident fund, ELSS, children’s tuition fees and other section 80C investments. A borrower who has already exhausted the ₹1.5 lakh cap through provident fund or insurance may get no additional relief from principal repayment.

The new tax regime changes the picture sharply. It is the default regime for many individual taxpayers, though eligible taxpayers may opt out and choose the old regime, and the lower slab structure can look attractive until deductions tied to housing fall away.

For self-occupied house property, the usual Home Loan interest deduction under section 24(b) is not available in the same way under the new regime. Principal repayment under section 80C is also generally not available under the new regime, which is where many taxpayers make errors after declaring a housing loan to an employer but filing later under the concessional system.

That can catch several groups at once. A salaried employee may expect a deduction that disappears at return filing, while NRIs with Indian rental income or returning residents with new salary income in India may find the tax regime they assumed was cheaper no longer works once housing deductions are included.

Property use also shapes the outcome. A self-occupied property is generally one the owner uses for personal residence, though treatment may still be available in some cases when the owner lives elsewhere because of employment, business or profession.

A let-out property follows a different path because rent is taxed under the head “income from house property” after permitted deductions. Interest on borrowed capital matters in that computation, and set-off and carry-forward restrictions must be checked carefully.

Vacant property creates another layer of confusion, especially for NRIs who buy homes in India and leave them unused except for parents, later return or occasional visits. The tax result may depend on whether the property is treated as self-occupied, deemed let-out or otherwise, and owners with more than one house should take particular care because assumptions for one property may not apply to another.

Timing matters as well for under-construction homes. Many buyers start paying EMI or pre-EMI interest before possession or completion, but that interest is not always claimed immediately in the same year.

Pre-construction interest is typically accumulated and then claimed in instalments after construction is completed, subject to the applicable overall limit. That means the date payment starts and the date deduction starts can differ, a point that affects younger salaried buyers who expect tax relief as soon as the first EMI leaves the account.

Records are central to those claims. Taxpayers should keep the lender’s interest certificate along with completion or possession documents, because those papers may be needed to support a deduction tied to an under-construction property.

For NRIs, the tax analysis runs beyond the Home Loan itself. Indian rental income can trigger TDS obligations for a tenant paying rent to a non-resident landlord, and a later property sale can bring capital gains and TDS rules into play.

Indian tax benefits also do not automatically create matching relief in the country where the owner lives. An NRI working in the United States, Canada, the UAE, the UK, Australia or Singapore may have to separately examine local tax rules, foreign income reporting, foreign tax credit and disclosure requirements.

A cross-border owner in the United States, for example, may reduce taxable income in India in some situations through the treatment of the Indian property loan, while U.S. tax treatment follows different rules. That is a warning against assuming a deduction claimed in India produces the same result abroad.

Returning residents face another shift because their filing position can change after they move back to India. A property bought as an investment while living abroad may become self-occupied, rental arrangements may end, salary income may begin in India and the taxpayer may move from NRI status to resident status.

That switch can affect the filing form, reporting obligations, house-property computation and the old-versus-new tax regime decision. Someone who saw little value in the old regime while abroad may find it more useful after returning if housing-loan interest, life insurance, provident fund contributions, tuition fees or other eligible deductions now apply in India.

One example uses a salaried taxpayer who pays ₹1.8 lakh as home-loan interest and ₹1.2 lakh as principal repayment during FY 2025-26. If that taxpayer chooses the old regime and satisfies the conditions, those figures may be relevant for deduction, subject to statutory limits.

If the same taxpayer chooses the new tax regime, the expected relief from section 80C principal repayment and self-occupied home-loan interest may not be available. The new regime can still work better if the slab advantage outweighs the lost deductions, which turns the choice into a numerical comparison rather than a routine claim.

A second example concerns an NRI who lets out an apartment in India. Rental income, municipal taxes, standard deduction, interest on borrowed capital, TDS and return filing obligations all have to be examined together, rather than treating the loan in isolation.

Documentation can decide whether a claim survives scrutiny. The loan sanction letter, annual interest certificate from the lender, principal repayment details, possession or completion certificate, sale deed or allotment letter, proof of municipal tax payment where applicable, rental agreement and rent receipts for let-out property, TDS certificates and evidence of ownership and co-ownership share are relevant.

Co-borrowers face a separate test. Being named on the loan is not enough by itself, because the person claiming the deduction should also be an owner or co-owner and should actually bear the repayment burden.

Several recurring mistakes stand out. One is assuming every borrower gets a flat deduction, another is trying to combine old-regime deductions with new-regime slab benefits, and another is claiming interest on an under-construction property too early without checking the timing rules.

It also flags the section 80C cap as a point many filers overlook. Once the ₹1.5 lakh limit is already filled by other eligible items, principal repayment may add no extra benefit, even though borrowers often continue to count it in their tax planning.

A final error is failing to compare both systems before filing. Many taxpayers focus on deductions alone and do not calculate final tax liability under both the old tax regime and the new tax regime.

The practical filing exercise is straightforward: compute tax under the new regime, compute tax under the old regime after eligible deductions, check whether the property is self-occupied, let-out, vacant or under construction, verify interest and principal figures from the lender’s certificate, review whether section 80C is already exhausted and, for NRIs, examine rental TDS, return filing and foreign-country reporting implications.

That leaves no single answer for all buyers. A filer with few or no deductions may prefer the new tax regime, while a filer with a Home Loan, provident fund contributions, insurance, tuition fees, HRA or other eligible deductions may find the old structure more useful.

A Home Loan in India can reduce tax, but it does not do so automatically. The benefit survives only when the return matches the correct tax regime, the property’s status is classified correctly and the supporting records hold up.
