Idaho Payroll Tax and Registration Guide

To stay compliant with Idaho’s payroll tax laws, you’ll need to provide specific details before you can begin running payroll through Beyond:

  • State Employer ID Number along with any local or state-specific tax identification numbers
  • Tax rates assigned to your business by the state based on factors like industry, size, and history
  • Third-party authorization (TPA) and Power of Attorney – necessary for Beyond to file reports and make payments on your behalf

 

It’s your responsibility to supply and update this information to ensure Beyond can accurately manage and submit your payroll tax filings. Beyond is not liable for any late fees, penalties, or interest caused by missing or incorrect company data.
