Form 16 Checks Before Filing ITR: 7 Crucial Details Salaried Taxpayers Must Verify
As the income tax return (ITR) filing season begins, most salaried employees eagerly wait for Form 16 from their employers. The document contains details of salary income, tax deductions and tax deducted at source (TDS), making it a key document for tax filing. However, relying on it blindly can be a costly mistake.
Tax experts warn that even minor discrepancies in Form 16 can lead to incorrect tax filings, missed deductions, loss of tax credits or even notices from the Income Tax Department. That is why performing a few essential Form 16 checks before filing ITR is critical for ensuring a smooth and error-free return filing process for Assessment Year (AY) 2026-27.
Understand the Difference Between Part A and Part B of Form 16
