Part 1: Legal Ways to Save Income Tax in India (FY 2026-27)

If you opt for the Old Tax Regime in India, the Income Tax Act provides multiple sections to claim deductions and lower your taxable income.
1. Key Deductions under Section 80C, 80D, and More
- Section 80C: Invest up to ₹1,50,000 annually in tax-saving instruments such as Public Provident Fund (PPF), Employee Provident Fund (EPF), Equity Linked Savings Scheme (ELSS) mutual funds, Life Insurance premiums, and National Savings Certificate (NSC).
- Section 80D (Health Insurance): Claim deductions on health insurance premiums paid for yourself, your family, and your parents (up to ₹25,000 for non-senior citizens and up to ₹50,000 for senior citizens).
- Section 24 (Home Loan Interest): Claim up to ₹2,00,000 on the interest paid towards a home loan for a self-occupied property.
- HRA (House Rent Allowance): Salaried individuals living in rented accommodations can claim HRA exemptions based on actual rent paid, salary structure, and city of residence.

Part 2: Legal Ways to Save Income Tax in the USA (Tax Year 2026)

In the United States, tax minimization revolves around maximizing pre-tax retirement contributions and utilizing IRS-approved deductions.
1. Smart Tax-Saving Strategies in the US
- Maximize Retirement Accounts: Contribute to a traditional 401(k), 403(b), or Individual Retirement Account (IRA). Contributions to these pre-tax accounts directly lower your adjusted gross income (AGI) for the year.
- Health Savings Account (HSA): If enrolled in a High-Deductible Health Plan (HDHP), contributions to an HSA are 100% tax-deductible, grow tax-free, and can be withdrawn tax-free for qualified medical expenses.
- Standard vs. Itemized Deductions: Choose between taking the standard deduction or itemizing deductions if your total deductible expenses (such as mortgage interest, state and local taxes up to limits, and charitable donations) exceed the standard threshold.
