Voluntary Disclosure

Business voluntary disclosure

Our voluntary disclosure program helps resolve prior tax debt. If your business isn't in compliance with Oregon tax laws, we encourage you to come forward.

Written request

Contact us in writing to ask to enter into a voluntary disclosure agreement. You may do this anonymously through a third party such as an accountant or lawyer. The agreement is only an option if:

  1. you haven't already filed returns for which you are seeking a voluntary disclosure agreement;
  2. you haven't already been contacted by us; or
  3. you haven't already been contacted by the Multistate Tax Commission (MTC).

Your written request must include:

  • A company description, including entity type and business activity conducted in Oregon.
  • The date Oregon business activity began.
  • The reason(s) for not filing Oregon tax returns.
  • The company's year-end date (calendar or fiscal year).
  • A specific statement of the relief requested, or the proposal being made.
  • A statement indicating whether the company or an affiliate was contacted by us or the MTC.
  • Requests that include Corporate Activity Tax, provide a statement indicating whether the company has registered for the Corporate Activity Tax and whether the taxpayer has made quarterly estimated tax payments.

If you haven't filed tax returns in multiple states, the MTC can contact the states for you to fulfill your filing requirements. Contact the MTC for more information.
