Income Tax Basics in India: Salary, Deductions, and Planning

Last updated: February 22, 2026

Tax confusion usually happens because people plan only in March. A better approach is to understand your taxable income early and spread decisions across the year.

Quick Answer

Start with annual salary breakup, identify your taxable income, compare old vs new tax regime, and track deductions monthly. This prevents last-minute mistakes and cash-flow stress.

Step-by-Step Framework

1. Collect CTC breakup: basic, HRA, allowances, bonus.
2. Estimate annual taxable income after exemptions.
3. Compare old and new regime with real numbers.
4. Plan deductions (if applicable) through the year.
5. Review Form 26AS/AIS and salary slips before filing.

Detailed Example

If your annual gross income is 10 lakh and eligible deductions are 1.5 lakh, your taxable base changes materially. Choosing the right regime based on actual deductions can save meaningful tax, while wrong regime selection may increase payable amount.

Action Checklist

• Maintain one tax folder: salary slips, investment proofs, rent proofs.
• Avoid tax products only for saving tax; match products to goals.
• Check TDS monthly and verify PAN details in payroll.
• File return on time even when refund is expected.

Common Mistakes

• Choosing tax regime without calculation.
• Submitting incomplete or incorrect investment proofs.
• Ignoring side-income tax impact.
