(Portland, OR) -- Portland City Council members are considering raising taxes on some businesses to help the city close its budget gap. The proposal would increase the city's climate tax from one-percent to one-point-three-percent. The tax is paid by retailers who bring in one-billion dollars in revenue nationally per year and at least 500-thousand dollars locally here in Portland. The city is currently trying to bring down a more-than-90-million-dollar budget gap.
