Donations up to $20 are matched 9-1 by the City of Portland which means a $20 contribution becomes $200. If you reside in the City of Portland and can donate $20, it means your entire donation is matched!
Donations up to $50 may be eligible for the Oregon Political Tax Credit, meaning you can get those funds back at the end of the calendar year. Income qualifications and other limitations may apply; more info can be found here: https://dpo.org/oregon-political-tax-credit/.
