So what do you think about corp to corp in and firm?

What?

I am sorry I just want to know about corp to corp in an firm

Never heard of it

It is related to taxes i.e, w2 and corp to corp

Are you saying a w2 is issued from one corp to another?

I don't know but I want to know about this so that I can manage things at my office

Since you don't know what terms you are referring to ask you question in simple terms.

It refers to w2 and I want to know about w2,w9 and FICA

Payroll taxes? OK now I know what you want. Since you know very little about payroll taxes and you have a corp, please contact a local accountant to handle your payroll taxes. It is very difficult to "teach"someone how to do payroll taxes on a computer. There are many payroll services such as paychex who can perform all payroll tasks including writing the checks to your employees.

Thanks for that but I want to know the meaning of this terms can u tell me please

Agreed! Your circumstances SCREAM for professional help.
