Campaign Finance in Candidate Elections

On November 6, 2018, voters amended the City of Portland Charter relating to the election of City of Portland candidates (Mayor, Commissioners, Auditor) by requiring contribution and expenditure limits in campaigns as well as requiring: disclosures on certain campaign communications, additional registration of expenditures with the Secretary of State, and employee political deductions via payroll. 

UPDATE ON LEGAL STATUS: Portions of the Charter Change currently valid and enforceable by the Auditor's Office due to recent legal proceedings are as follows: 

As of April 29, 2020:  Portland City Code Section 2.10.010 and City Charter Section 3-301, Contributions in City of Portland Candidate Elections. The Auditor's Office will enforce contribution limits as outlined in these regulations beginning Monday, May 4, 2020 in order to give campaigns and individuals time to comply. 

Contribution limits will not be enforced retroactively. 

As of September 1, 2019:

  • Independent Expenditure registration (via OR Secretary of State campaign finance database): City Charter Sections 3-302(b) and Portland City Code Sections 2.10.020(B).

  • Employee Political Committee donations through payroll deduction (for all Portland employers): City Charter Sections 3-301(c) and Portland City Code Sections 2.10.010(C).

Based on recent legal proceedings, the remaining portions of the Charter Change are invalid and not enforceable by the Auditor's Office.
