LLC and tax id
As every state has different costs to register an LLC, the fees would vary depending on the state your business would be registered in. Some states may have additional requirements to the state filing fee, such as a mandatory state tax registration or newspaper publications.
Depending on the type of business you would be conducting, you may also require additional licenses/permits. Without knowing the nature of your business, I would not be able to give you an accurate cost amount to satisfy your business needs.
