(Portland, OR) -- Multnomah County is sending notices to nearly 300-thousand households that they might need to pay the Preschool for All Personal Income Tax. It was approved by voters in 2020, and connects three- and four-year-olds with preschool programs. A little over 700 slots were funded in the first year. Students will be added until 2030 when the program will cover all children. The tax applies to single filers making over 125-thousand dollars a year or joint filers making over 200-thousand dollars. The tax needs to be paid separately at Pro.Portland.Gov. Some tax software does include the tax.
