I am sorry, but while you should not do it, as stated, you need to be causcious because there are circusmtances in which you may not transfer the tax ID number from one business to another.
A tax id for a business is normally called an EIN number. Please follow:
If you already have an EIN, and the organization or ownership of your business changes, you may need to apply for a new number. Some of the circumstances under which a new number is XXXXX are as follows:
You may not transfer the tax id number form a seperate business to your business.
However you do not need a new EIN number If:
1. You change the name of your business.
2. You change the business location
3. You operate multiplel businesses.
BUT even if you acquire another business and bring it under your operation, you can change ownership. BUT if that business has a seperate EIN and you have an EIN for yours, you can not bring the two together. Each business has to be operated seperately or you have to retire one number.
