How Much Income Tax Can Salaried Professionals Save by Buying a Home in Chennai?

What is the Income Tax Benefit on a Home Loan?

A home loan can help you save income tax because part of your EMI includes principal and interest. 

Under the 2026 new tax regime, you don’t get benefits on principal or interest for a self-occupied house, but you can claim a full interest deduction if the property is rented, which helps reduce tax on rental income. 

Under the old tax regime, you can claim up to ₹1.5 lakh on principal (Section 80C) and up to ₹2 lakh on interest (Section 24), making it better for tax savings.

The report says about 72% of taxpayers chose the new tax regime in 2024–25 because it is simpler and has lower tax rates. (Source)

What Changed in the New Tax Regime (2026)

The new tax regime is now the default system. It focuses on lower tax rates and fewer deductions. Here’s what salaried individuals get in 2026:

• Standard deduction of ₹75,000
• Rebate benefits that can make income up to ₹12 lakh effectively tax-free
• Simplified tax slabs

At the same time, several deductions are no longer available:

• Section 80C (PF, LIC, ELSS, principal repayment)
• Interest deduction for self-occupied property (₹2 lakh benefit removed)

Because of this, many people assume that home loans no longer provide any tax benefit. But that is only true for self-occupied properties.

Documents Required for Home Loan Tax Exemption

• Interest certificate from the bank
• Loan sanction letter
• Loan repayment statement
• Sale deed / purchase agreement
• Possession certificate
• Completion certificate
• Rental agreement (if rented)
• Rent receipts or bank statements showing rent received
• Property tax receipts (if applicable)

How to Save Income Tax on a Home Loan?

1. Claim Interest Deduction Under Section 24(b)

The most important tax benefit in a home loan comes from the interest you pay, not the principal. Under Section 24(b), the treatment is different based on how you use the property.

If the property is self-occupied (you live in it), then under the new tax regime, you do not get any deduction on interest. This is a major change from earlier, when you could claim up to ₹2 lakh.

But if the property is rented out, you can claim 100% of the interest paid on your home loan. There is no upper limit.

Let’s say:

• Your annual home loan interest for apartment in Anakaputhur is ₹3 lakh
• Your rental income = ₹2.5 lakh

You can deduct the full ₹3 lakh from the rental income. This makes your taxable income from the property much lower (or even zero). This is the best way to save on tax through a home loan in 2026.

2. Use the 30% Standard Deduction on Rental Income

Before your rental income is taxed, the government allows a flat 30% deduction.

This is called the standard deduction for property income. It is given for maintenance, repairs, and other expenses, even if you don’t actually spend that amount.

Example:

• Rental income = ₹3 lakh
• 30% deduction = ₹90,000

So only ₹2.1 lakh is considered for tax. Now from this ₹2.1 lakh, you can still subtract your home loan interest. This double benefit (30% deduction + interest deduction) is what reduces your taxable income significantly.

3. Combine Interest and Standard Deduction for Maximum Benefit

The real advantage comes when you use both deductions together.

Example:

• Rental income for your flat in a 3 BHK flat in Velachery is ₹3 lakh
• After 30% deduction = ₹2.1 lakh
• Interest paid = ₹3 lakh

Now: ₹2.1 lakh – ₹3 lakh = ₹90,000 loss. This means you earned rent. But your taxable income from property becomes zero. So you don’t pay tax on your rental income.

This is how you make your property tax-efficient, even if it is not highly profitable on paper.

4. Understand What You Cannot Do (Very Important)

This is where most people misunderstand the rules.

Under the new tax regime:

• You cannot use this loss to reduce your salary income
• You cannot carry forward this loss to future years

Example:

If your loss is ₹90,000, earlier it reduced your salary’s taxable income. Now, it only applies to rental income. So the benefit is limited.

Understand, the goal is not to reduce your salary tax but to avoid paying tax on rental income.

5. Don’t Forget the ₹75,000 Standard Deduction (Salary)

Every salaried individual gets a ₹75,000 standard deduction. This is separate from your home loan. It directly reduces your taxable salary and requires:

• No investment
• No proof

For example: If your salary is ₹10 lakh, after deduction, only ₹9.25 lakh is taxable. This is the only fixed and guaranteed benefit available in the new tax regime.

To Note

This approach does not work equally in all cases. It works best under certain conditions. It works well when:

• Your loan interest is high (especially in the first few years)
• Your rental income is moderate
• Your property is in a high-demand rental area

In cities like Chennai:

• Rental yields are around 3 to 5%
• Loan interest is higher in early years

This naturally creates a gap where:

• Interest > Rent
• Result → Lower taxable income

Old vs. New Tax Regime: Which is Better in 2026?

Choosing between the two depends on your situation.

The old tax regime is better if:

• You rely on deductions like 80C and home loan principal
• You have a self-occupied property
• Your income is relatively lower
  

The new tax regime is better if:

• Your salary is ₹20 lakh or more
• You prefer lower tax rates
• You invest in rental property
  

One advantage is flexibility. You can choose between the old and new regimes every year when filing your income tax return. This allows you to compare and pick the better option.

Home Loan Benefits Lost in the New Tax Regime (AY 2026-27): To avoid confusion, you should clearly know what is not allowed under the new tax regime. You cannot claim:

• Section 80C (principal repayment, LIC, ELSS, PF)
• Interest deduction for self-occupied property
• Loss adjustment with salary

This is why many people feel tax savings are reduced. But the system is now simpler; you just need to use the remaining benefits correctly.

Conclusion

For salaried professionals in Chennai, tax planning in 2026 is no longer about simply investing in traditional deductions. It is about understanding how different financial decisions work together.

Buying a home and renting it out is one such approach. When done correctly, it can help you reduce tax, earn steady income, and build long-term wealth.
