Who do I call about my Washington state tax return?

Who do I call about my Washington state tax return?

The correct answer to this question requires a definition of the tax type. Washington utilizes a business & excise tax structure — rather than a personal income tax system. The tax type maps the inquiry to the correct agency.

Do I need to file a Washington income tax return?

No. Washington statutes do not establish a personal income tax. Consequently, residents do not file a generic "Washington state return."

Which office handles Washington state tax returns and notices?

The Washington Department of Revenue (DOR) manages state excise filings, payments & notices.

Fast contact options:

  • Tax assistance: 360-705-6705
  • Online filing support (My DOR): 360-705-6709

Taxpayers who owe the capital gains excise tax should file the WA return & upload a copy of their filed federal income tax return — with required schedules/documentation — for the same year.
