Preparing Documents for Last 3 Years

Collect Form 16, TDS certificates, bank statements, investment proofs, and property details for each relevant financial year. Organizing these documents reduces errors and speeds up the ITR filing process.

Digital Access and Backup

Ensure you have digital copies of all documents stored securely in cloud storage or on encrypted devices. Verify that login credentials for the income tax portal are accessible to avoid delays.

Filling ITR Forms Correctly

Choosing the Right Form

Select ITR-1, ITR-2, or other appropriate forms based on your income sources and residency status. Each form has specific eligibility criteria that must be matched carefully.

Cross-Checking Data

Validate all figures entered, such as income, deductions, and tax paid at source. Mismatches can trigger notices or delay refunds, so accuracy is critical.

Use the acknowledgment number to track the processing status on the portal. Updates regarding refunds, scrutiny, or rectification requests appear in your account dashboard.
