Effect on General Ledger if payroll changes a tax identification

cpashley

Our payroll department wants to bring one of our other affiliates into our payroll system. Each company has been doing their own payrolls under different tax identification numbers. They want to now have the one company be merged under the other company's tax id. Has anyone done this before and what effect would it have on the General Ledger? We currently use process levels to identify the separate companies within our organization.
