Obtaining a Form 16 from your company is crucial since it provides information about your pay, deductions, and exemptions. Form 26AS, on the other hand, will be available in your income tax portal and will contain combined details of Form 16 part A and Form 16A. For example, you can use Form 26AS, which will have consolidated data of all the TDS done in the financial year, to claim the TDS rather than referring to each and every Form 16A.
