What is Form 16?

Form 16 is given by the employer after the end of every financial year, usually on or before 15th June. This form contains details of how much salary you received and how much tax was deducted from it during the entire year. It also works as proof that your employer has deposited the TDS amount with the government.

Form 16 has two parts, called Part A and Part B. Part A only has the TDS details, such as the amount deducted and submitted. Whereas Part B contains a breakup of your salary, deductions under sections like 80C and 80D and your final taxable income. This form is very important for salaried individuals and should be checked properly to make sure all income details are correct before filing the return.

What is Form 26AS?

Form 26AS, also called as tax credit statement which gives you complete details about the taxes that have been deducted and deposited on your behalf by various parties. It includes information like TDS deducted from your employer, bank or any company. It includes various information such as TDS deducted from your salary, interest earned from banks, sale of property, any advance tax paid by you, and any assessment tax.

Form 26AS also includes basic details of your bank or company. You can check whether the tax that was deducted has been properly deposited into the government’s account or not with the help of this form. It is very useful during the calculation of your total tax liability.

What is AIS?

AIS stands for Annual Information Statement, introduced by the Income Tax Department in the year 2021. This form gives a complete picture of your financial activities throughout the year. It includes details about your income from various sources such as salary, interest from banks, dividend income, mutual fund transactions, stock market dealings and other high-value transactions.

You can view your AIS on the Income Tax e-filing portal. You can match your declared income with the information available to the tax department by using it. If there is any mismatch between your Income Tax Return and the AIS, then the Income Tax Department may send you a notice or query. So it is important to check this form properly before filing your return.
