Important Updates to Multnomah County’s Preschool for All Income Tax

Multnomah County has adopted amendments to the Preschool for All income tax program aimed to improve tax administration and compliance. Some of these key changes include:

  • Electronic Filing: The County wants to authorize the Tax Administrator to require electronic filing of tax returns through administrative rules.
  • Pass-Through Income Deduction Clarity: The language regarding the deduction of pass-through income will be clarified to make it easier for taxpayers to understand and apply.

The Preschool for All income tax program was started in 2021 to fund universal, tuition free, voluntary, and high-quality preschool education for every three- and four-year-olds residing within Multnomah County.
