Form 16 Explained: How Part A and Part B Help Salaried Employees File ITR Correctly

Form 16 is one of the most important documents for salaried taxpayers while filing their Income Tax Return for FY 2025-26, because it shows how much salary was paid, how much tax was deducted and how taxable income was calculated by the employer. The document is divided into two key sections: Part A and Part B. Part A works like a TDS certificate and contains details such as the employer’s TAN, employer and employee PAN, assessment year, employment period, tax deducted at source and tax deposited with the government. This section helps taxpayers confirm whether the tax deducted from salary has actually been reported and paid by the employer. Part B, on the other hand, gives the detailed salary breakup and tax computation, including basic salary, allowances, perquisites, exemptions, standard deduction, deductions under Chapter VI-A such as 80C, 80D and other eligible sections, taxable income and final tax liability. For salaried employees, Part B is especially useful because it shows how the employer arrived at the taxable salary figure and which deductions were considered before deducting TDS. However, taxpayers should not blindly copy Form 16 details into the ITR without checking them. Salary income, TDS, deductions, exemptions, bank interest, capital gains, house property income and other details should be cross-verified with Form 26AS, AIS and TIS before filing. If there is a mismatch between Form 16 and the tax department’s records, the taxpayer should contact the employer or verify the source of the mismatch before submitting the return. Form 16 is a helpful starting point, but the responsibility for correct ITR filing remains with the taxpayer. For FY 2025-26, salaried individuals should carefully review both Part A and Part B, download supporting documents, check deductions properly and file before the due date to avoid last-minute errors, notices or refund delays.
