What is Income Tax Declaration (ITD)?

An Income Tax Declaration is a document submitted by the employee to the employer. This document includes all the information about the total income and expenses of the employee Section 192 of the Income Tax Act of 1961 mandates employers to deduct the tax at source (TDS) while paying salaries to their employees. All income and expenses such as gross income, and proof of tax-saving investments such as insurance and PF, among others, for the year should also be provided. Employers use this information in the tax declaration to understand, determine, and deduct the TDS applicable based on the monthly income of the employees.
