Tax ID (EIN Number)
Almost all businesses need an EIN(Employer Identification Number). You can use your social security number as an EIN number if you are a sole proprietorship and if you do not have employees, but even then you still might want to consider getting an EIN since your social security number should be kept confidential. For all practical purposes you can consider the EIN number to be the Social Security Number for your business.
You will definitely need an EIN number if you have employees or have an advanced business type such as Corporation or LLC.
