Whether you're a salaried employee, freelancer, or small business owner, filing your ITR correctly for Assessment Year 2026–27 is important not only for tax compliance but also for maintaining a strong financial record.

1. A properly filed ITR helps you:
2. Claim tax refunds faster

In this step-by-step guide, you’ll learn everything you need to know about filing your ITR online in a simple and practical way.

Step 1: Understand the Financial Year and Assessment Year

Before filing your return, it’s important to understand these two terms:

• Financial Year (FY 2025–26): The year in which you earned your income
• Assessment Year (AY 2026–27): The year in which that income is assessed and taxed

For example, income earned between 1 April 2025 and 31 March 2026 will be filed in AY 2026–27.

Step 2: Collect All Required Documents

The most important part of smooth ITR filing is keeping your financial documents ready beforehand. Proper documentation reduces mistakes and helps you claim all eligible deductions.

Form 16

If you are salaried, your employer provides Form 16, which contains:

1. Salary details
2. Tax deducted at source (TDS)
3. Employer information

If you changed jobs during the financial year, collect Form 16 from all employers.

Form 26AS

Form 26AS shows:

1. TDS deducted
2. Tax payments

Always verify that your TDS matches your salary slips and bank records.
