You…

  • Haven't filed income tax returns for one or more years.

  • Live in another state but work in Idaho and haven't filed.
  • Conduct business in Idaho and haven't filed.
  • Have employees and need a withholding permit.
  • Make sales in Idaho and need a sales tax permit.
  • Are unsure about whether you have to file returns.

Penalties

Although we can't waive interest, we'll consider reducing any penalties that apply if you file your return voluntarily.
