Changes to existing businesses
If you're buying a business
Buying a business without verifying that the business is up to date on its taxes increases your risk of a surprise tax liability. Request a Successors' Liability clearance letter to verify whether the business has a sales/use tax debt for which you could be liable.
As the new owner, you should also apply for new Idaho tax permits for the business (e.g., sales, withholding, cigarette, wine). The prior owner is responsible for canceling the tax permits obtained while the owner of the business (see Idaho Sales and Use Tax Rule 70.04).
