How frequently companies file taxes of employees?

 If you are an employee, your employer probably withholds income tax from your pay. The amount withheld is paid to the IRS in your name. Estimated tax is used to pay not only income tax, but self-employment tax and alternative minimum tax as well.

Sir,

I need to know how "Frequency= Monthly, yearly" taxes are filed by the company which can be traced by me using my PAN card number
