Tax shields are legal deductions that help reduce your taxable income, which in turn lowers the amount of tax you owe. These deductions come in various forms—like home loan interest, depreciation, business expenses, and medical premiums.


Whether you are a salaried individual or a business owner, understanding how to use tax shields effectively can help you save more and plan your finances better.

How are tax shield used?

Let’s break down some of the most common types of tax shields used in India:


1. Home Loan Interest Deduction (Section 24b)

If you're paying interest on a home loan, you can claim up to Rs. 2 lakh as a deduction under Section 24(b). This lowers your taxable income and offers considerable annual savings.

2. Depreciation on Capital Assets

Businesses can claim depreciation on assets like machinery and equipment. This deduction reduces taxable profits, allowing firms to reinvest more back into the business.


3. Interest on Business Loans

Interest paid on loans—like working capital loans or term loans—can be deducted as a business expense. It not only reduces your tax liability but also brings down the effective cost of borrowing.


4. Medical Premiums and Expenses

Premiums for health insurance (under Section 80D) and certain medical treatments (under Section 80DDB) can also act as tax shields. These not only safeguard your health but also reduce your tax outgo.


5. Investments in Tax-Saving Instruments

Options like Public Provident Fund (PPF), National Pension System (NPS), and Employee Provident Fund (EPF) offer deductions under Sections 80C and 80CCD. These promote long-term savings while cutting down taxes.

6. Charitable Donations (Section 80G)

Donations to eligible NGOs and relief funds can also be claimed as deductions. This provides a tax advantage while contributing to a social cause.


7. Day-to-Day Business Expenses

Salaries, rent, utilities, and marketing costs are all deductible for businesses. These tax shields help manage operating costs and optimise cash flow.

Tax Shield Formula

Here’s how to calculate the benefit from a tax shield:

Tax Shield = Deductible Expense × Tax Rate

This formula helps quantify your potential tax savings and make smarter financial choices.


Real-Life Example: Tax Shield on a Home Loan

Suppose you pay Rs. 2,00,000 in annual interest on your home loan. If you're in the 30% tax bracket, your tax savings would be:


Tax Shield = Rs. 2,00,000 × 30% = Rs. 60,000


That’s Rs. 60,000 saved—just from your home loan interest.

Business Use Case: Interest Tax Shield

Let’s say a company borrows Rs. 50 lakh at 10% interest. That’s Rs. 5 lakh in annual interest.

At a 30% tax rate, the tax shield is:


Rs. 5,00,000 × 30% = Rs. 1,50,000


This effectively lowers the cost of borrowing and improves the firm’s bottom line.

Conclusion

Tax shields are a powerful financial tool that can significantly reduce your tax burden—whether through home loan interest, business expenses, or medical premiums. By understanding how to use them strategically, individuals and businesses can improve cash flow, enhance savings, and plan better.
